5.01  This chapter considers various aspects of set-off between solvent parties.

A. Charterparties and Bills of Lading

(1)  Equitable set-off and abatement – freight under a voyage charter or bill of lading

5.02  Questions of set-off in the context of charterparties have been the subject of particular attention in recent years.1 In that regard the courts have drawn a distinction between, on the one hand, freight payable under a voyage charter or bill of lading, and on the other hire payable under a time charter or a charter by demise.2 In the former case, equitable set-off generally is not available, whereas it may apply in the latter.

5.03  There is a general common law principle whereby the defendant in an action for payment of the price of goods sold with a warranty, or of work to be performed according to a con-tract, can deduct the amount of any damage sustained by the defendant by reason of a breach of warranty or contract. This is not by way of set-off, but rather it is a means by which the defendant can defend him-or herself by showing how much less the subject-matter of the contract is worth as a result of the claimant's breach. This principle, known as abatement, or the rule in Mondel v Steel,3 was considered earlier.4 However, the right to abate does not apply to every contract for work and labour. It was established early in the nineteenth century5 that, in the case of a contract for the carriage of goods by sea, a bill of (p. 165) lading holder or a voyage charterer cannot make a deduction from the freight payable6 except to the extent specifically allowed by the contract.7 As a consequence of this exception,8 a defence of abatement has failed in cases involving damage done to the goods being shipped,9 short delivery10 and delay.11

5.04  It is unclear whether the rule against deductions from freight was originally thought to extend to the equitable defence of set-off as well as the common law defence. In Stimson v Hall12 a lighterman brought an action against the owner of goods for freight owing for the conveyance of the goods. The goods owner alleged that other goods had been lost as a result of the negligence of the lighterman,13 and said that his cross-claim for damages for the loss of those goods gave rise to an equitable defence to the claim. While the Court of Exchequer rejected this contention on the ground that the facts failed to disclose a natural equity sufficient to ground a set-off, there is nothing in the judgments or in the arguments of counsel to suggest that an equitable set-off was considered to be unavailable in any event against a claim for freight. However, the courts have since accepted that equitable set-off is subject to the same restriction as for common law abatement with respect to the payment of freight.14 The restriction is not confined to cases of loss of or damage to goods (p. 166) or delay,15 but applies to any damages claim available to the charterer or bill of lading holder.16 In Bank of Boston Connecticut v European Grain and Shipping Ltd,17 the House of Lords confirmed that the restriction extends to the situation in which the voyage was never completed as a result of the shipowner's wrongful repudiation of the charterparty, in circumstances where the right to freight had accrued under the charterparty before it was terminated by acceptance of the repudiation.18 Moreover, it applies equally to advance freight and to freight payable on delivery of the goods at the port of discharge.19 It has also been held to extend to a claim for additional freight, in circumstances where additional freight became payable because of the owner's own breach of contract.20

5.05  The principle precluding deductions is not limited to the situation in which a shipowner is suing a voyage charterer or a bill of lading holder for freight. An agent who collects freight on behalf of the shipowner or charterer must account for the freight without deduction or set-off.21 Similarly, a freight forwarder who arranges carriage as agent for a goods owner, and who pays the cost of carriage on behalf of the owner, is entitled to be reimbursed with-out a set-off in respect of an allegation of breach of duty as agent.22 The principle is also relevant when the right to freight has been assigned. The assignee is entitled to the freight undiminished by an equitable set-off.23

(p. 167) 5.06  Nor is the principle confined to shipping. Contracts for the carriage of goods by road pursuant to the Convention on the Contract for the International Carriage of Goods by Road (CMR) are subject to the rule,24 even though Articles 32 and 36 of the Schedule to the Convention seem to contemplate that set-offs are possible. Further, it has been held, albeit with reluctance, that the principle is equally applicable to a domestic contract for carriage by land.25 It would probably also apply to a contract for carriage of goods by air.26

5.07  In the Bank of Boston case,27 the House of Lords warned that the rules of procedure should not be used to bring about a result contrary to the principle. Lord Brandon of Oakbrook, who delivered their Lordships’ judgment, rejected an argument that the court could try both the claim and the counterclaim and then make an order pursuant to the former Ord. 15, r. 2(4) RSC. The rule provided that: ‘Where a defendant establishes a counterclaim against the claim of a plaintiff and there is a balance in favour of one of the parties, the court may give judgment for the balance …’ He said that to utilize the rule for that purpose would constitute a wrong exercise of the court's discretion. Similarly, a cross-claim available to a charterer ordinarily does not constitute a ground for staying execution on a judgment obtained against the charterer for payment of freight.28

5.08  While freight must be paid without deduction in respect of a damages cross-claim, Judge Diamond QC in the Commercial Court suggested that, in the case of an arbitration, when an arbitrator is called upon to exercise his or her discretion to make an interim award in respect of freight, he or she may make it a condition of the issue of the interim award that the owner provide reasonable security for the charterer's cross-claim. He also suggested that there ‘may perhaps’ be exceptional cases where an arbitrator in the exercise of his or her discretion may find a valid reason for refusing to issue an interim award in respect of a claim for freight, but he conceded that those cases would be rare.29

5.09  On the other hand, the freight rule does not apply when a shipowner has presented a petition to wind up a company for non-payment of freight and the company has a genuine and serious cross-claim against the petitioner. If the amount of the cross-claim exceeds the debt to the shipowner, the court may dismiss or stay the petition unless there are (p. 168) 30 special circumstances which make it inappropriate for the petition to be dismissed or stayed.

(2)  Equitable set-off – hire under a time charter

5.10  Different considerations apply to hire payable under a time charter.31 Admittedly, it was assumed in Russell v Pellegrini,32 after a concession by counsel to that effect, that a cross-claim for damages for breach of an implied warranty of seaworthiness could not be set off against a claim for hire,33 while more recently Donaldson J applied the freight rule in that context in two unreported decisions on interlocutory applications,34 and later in Seven Seas Transportation Ltd v Atlantic Shipping Co SA.35 Subsequently, however, Parker J in The Teno36 followed an unreported decision of Ackner J to the contrary,37 and held that the rule by which freight must be paid without deduction does not extend to hire. Parker J's judgment received the approval of the Court of Appeal in Federal Commerce & Navigation Co Ltd v Molena Alpha Inc,38 and the principle has since become accepted.39 It applies in the case of a charter by demise (sometimes called a bareboat charter),40 as well as when a time charter is expressed to be for the period of a particular voyage,41 so that in substance it resembles a voyage charter.42

(p. 169) 5.11  This right to an equitable set-off against a claim for hire is not confined to cases in which there has been a total withdrawal of the vessel for a specified time.43 A set-off against hire may take place when the master has wrongfully refused to load a full cargo,44 and when a speed warranty has been breached.45 An equitable set-off may also be available when the shipowner has failed to perform its hold-cleaning obligations resulting in a delay to the vessel at port,46 and when the vessel had to proceed to another port to discharge the cargo because of contamination which was caused by the owners’ breach of the charterparty.47 A time charterparty may contain a stipulation to the effect that the owner must provide and pay for all provisions and wages, insurance, and deck and engine-room stores. If the owner fails to make those payments and the charterer, in order to ensure the vessel's availability and use, instead expends the money, the charterer's damages claim against the owner for breach of the clause may be employed in a set-off against hire.48

5.12  It is not every cross-claim that can be set off. In Federal Commerce v Molena,49 Lord Denning suggested that the right of deduction should be limited to cases where the owner through its neglect or default has either deprived the charterer of the use of the vessel or has hindered or prejudiced the charterer's use.50 For example, both he and Lord Goff in that case said that a deduction would not be available when the cross-claim arises merely from damage to cargo. Similarly, a charterer may not set off the estimated value of bunkers remaining on re-delivery of the vessel, unless the charterparty specifically sanctions a deduction.51 The principle is illustrated by The Leon.52 Charterers alleged three breaches by the owners: (1) that the master had failed to keep full and accurate logs of the fuel consumption; (2) that the master had procured that invoices which did not represent the fuel actually taken on board should be sent to and paid for by the charterers; and (3) that the owners had breached their duty as bailees of the bunkers to use them during the charterparty in (p. 170) accordance with the charterer's orders. It was held that none of the breaches affected the use of the vessel, and that consequently they did not give rise to a set-off against hire. Hobhouse J emphasized, however, that there was nothing to show ‘overriding fraud’ on the part of the owners. If there had been, he suggested that the result may have been different.53

5.13  Lord Denning's later judgment in The Aliakmon Progress54 suggested a narrower scope to the set-off than that described in Federal Commerce v Molena. A vessel the subject of a time charter sustained damage while attempting to berth at a port in Iceland. Temporary repairs were effected there, and the vessel then sailed to Antwerp where permanent repairs were undertaken. Owing to the resulting delay the vessel lost an anticipated cargo at Antwerp and had to wait some thirty-nine days for a new cargo. Lord Denning, with whom Geoffrey Lane LJ agreed, doubted that the loss sustained by the charterers constituted a ground for equitable set-off. He cited Federal Commerce v Molena as authority for the proposition that equitable set-off is only available against a claim for hire ‘where the charterers have been deprived of the use of the ship by the fault of the owner’.55 He said that, in the case before him, the charterers did in fact have the use of the ship but could not get a cargo. There was no mention of whether a set-off may arise when the shipowner merely prejudiced the charterer in the use of the vessel, and there was no discussion of whether in the instant case there had been any such prejudice. Subsequently, however, the courts have reiterated that prejudice in the use of the vessel not amounting to total deprivation may ground a set-off.56

5.14  Counsel in The Leon57 attacked the proposition that equitable set-off in the context of time charters should be limited to cases in which the charterer has been deprived of or prejudiced in the use of the vessel. Rather, it was suggested that the allowance or otherwise of a set-off should be determined by reference to whether it would be unfair in the particular case to allow the owner to sue for hire without giving credit for the cross-demand. However, Hobhouse J declined to depart from the statements of the ambit of the set-off by Lord Denning and Goff LJ in Federal Commerce v Molena, and emphasized that the relevant principle is set out in Lord Cottenham's judgment in Rawson v Samuel,58 that the equity of the bill must impeach the title to the legal demand.59 In the case of a time charter, hire is paid for the right to use the vessel for a specified period of time, irrespective of whether the charterer chooses to use it for carrying cargo or instead lays it up out of use. The hire is required to be paid in advance, and failure to make punctual payment gives the owner the right to withdraw the vessel. In those circumstances, Hobhouse J said that it is not a coincidence that, in cases where the right to an equitable set-off was upheld, the cross-claim (p. 171) involved something which could be identified as depriving the charterer of the use of the vessel or which prejudiced or hindered that use, because, in the context of a time charter contract and a claim for time charter hire, it is that type of cross-claim which has the requisite effect of impeaching the plaintiff's demand.60

5.15  In a case where hire is payable periodically under a time charter, the charterer may have been prejudiced in the use of the vessel only in certain defined periods. In other periods the vessel may in fact have been made available in accordance with the contract. If the charterer's damages claim in such a case exceeds the amount of hire owing for the periods during which the use of the vessel was prejudiced, the charterer may wish to set off the excess against payments of hire relating to other periods. The question whether this is permissible was considered earlier.61

(3)  The justification for the freight rule

5.16  Given that there is this distinction between freight and hire as regards equitable set-off, the question arises whether there is any justification for it. It has been suggested that the original justification for the freight rule may have been based upon cash flow considerations, in that the master would require the freight to be paid in full at the end of the voyage in order to pay off the crew, and to refit and victual the ship. Communications in those days were slow, and the master could not wait a long time for funds to be remitted.62 Yet, in the context of building contracts, the courts have said that cash flow considerations are not a sufficient reason for denying a set-off.63 Lord Wilberforce, on the other hand, doubted whether the freight rule indeed is anything other than an arbitrary rule, ‘in the sense that no very clear justification for it has ever been stated and perhaps also in the sense that the law might just, or almost, as well have settled for a rule to the opposite effect’.64 Despite this, he concluded that the rule is too well established to be departed from now.65 There are, nevertheless, dicta to the effect that it should not be extended,66 and the attitude of the (p. 172) courts has been that voyage and time charters are sufficiently dissimilar in their operation to justify the application in the case of hire of the general rule permitting deductions, rather than having resort to the exception precluding deductions found in the freight rule. Thus, Lord Denning, in justifying the distinction, noted that freight is the sum payable for the carriage of goods from one place to another, while hire is paid for the right to use the vessel for a specified period of time irrespective of whether or not the charterer chooses to use it for carrying cargo.67 But even this as a basis for treating them differently becomes blurred when a time charter is for the period of a particular trip.68

(4)  The Statutes of Set-off

5.17  A question in respect of which conflicting opinions have been expressed is whether the principle which precludes a defence of equitable set-off against a claim for freight also extends to the defence provided by the Statutes of Set-off in the case of mutual debts.69

5.18  The cases favour the view that the freight rule does not apply in this context.70 In Wilson v Gabriel,71 the defendant in an action for payment of freight pleaded set-off as a defence, based upon an unconnected debt owing by the plaintiff. The plaintiff replied, on equitable grounds,72 that when the freight was in the course of being earned he had assigned it for value to a third party, and that the plaintiff brought this action as trustee for the third party. The Court of Queen's Bench held that this did not to constitute an answer to the plea, the defendant not having had notice of the assignment before the mutual debts arose.73 Cockburn CJ74 and Blackburn J each accepted that the defendant was entitled to a set-off at law against the liability for freight, and that it was not affected by the assignment. Since this was after the courts had adopted the principle that the common law defence of abatement does not extend to freight,75 it is evident that the statutory defence was thought to be subject to different considerations. The contrary view, however, was accepted in The Khian (p. 173) Captain (No. 2).76 Hirst J held in that case that set-off under the Statutes is subject to the freight rule, and suggested that Wilson v Gabriel was impliedly overruled by the House of Lords in Aries Tanker Corporation v Total Transport Ltd.77 The issue in the Aries Tanker case, however, was whether a damages claim in respect of cargo could be applied in reduction of a liability for freight either on the basis of equitable set-off or common law abatement. The House of Lords held that those defences did not apply. The statutory defence of set-off was not in issue, and nor was it considered. Subsequently, Hobhouse J at first instance in the Bank of Boston case78 disagreed with Hirst J. He accepted that a freight debt and another debt can be set off under the Statutes, and that Wilson v Gabriel was not overruled by Aries Tanker.

5.19  Apart from The Khian Captain, it is difficult to find authority for the proposition that the Statutes do not apply in this context.79 Two cases which have been said to support that view80 are explicable on other grounds.

5.20  In Weguellin v Cellier,81 consignees of cargo had accepted six-month bills of exchange at the request of the shipowner. The shipowner assigned the freight payable by way of security to the respondents, who then brought the present action seeking a declaration that they were entitled to be paid the freight. However, the consignees, having honoured the bills, had a claim against the shipowner, and argued that this gave rise to a set-off against the liability for freight and that the respondents as assignees took subject to the set-off. It is apparent that any right of set-off would have arisen under the Statutes, based upon mutual debts, given that the demands would not have been sufficiently closely connected to give rise to an equitable set-off. While Lord Chelmsford held that there was no such set-off which would defeat the respondent's right to the freight, this was not because of a general principle that a claim for freight is not susceptible to a defence of set-off under the Statutes. In the first place, as counsel for the respondents argued, the bills did not mature until after the consignees received notice of the assignment, so that at the date of notice there was no accrued debt owing by the shipowner. An assignee does not take subject to a cross-debt which arises after notice, albeit as a result of a prior contract.82 But even apart from that, the Statutes of Set-off only provided a procedural defence to an action for payment of a debt; until a judgment for a set-off is obtained, separate and distinct debts (p. 174) remain in existence.83 In Weguellin v Cellier, when the goods arrived at the port of discharge the respondents put a stop on them. They had a lien and, as Lord Chelmsford pointed out, the consignees could not have obtained the cargo without payment of the freight, and the master of the ship would have been bound to insist upon payment before delivery.84 Because of the procedural nature of the defence of set-off, the consignees could not have acted unilaterally to bring about a set-off so as to obtain the release of goods the subject of the lien. The circumstances in Weguellin v Cellier were different, in that the consignees after some correspondence had paid the amount of the freight to the dock company holding the goods so as to obtain their release, and the respondents then filed a bill seeking a declaration that the freight in the hands of the dock company should be applied towards payment of what was due to them by the shipowner.85 But it was still not a case of set-off under the Statutes, because it was not an action against the consignees for payment.

5.21  The second case, Tanner v Phillips,86 similarly may be explained on other grounds. The plaintiff was mortgagee of a ship, and as further security held a mortgage of freight. The ship was chartered to the defendant. The charterparty provided that the defendant could make advances not exceeding £150 to the master as agent for the mortgagor/owner on account of freight, though other advances in excess of that amount were made. Before the cargo was unloaded and freight became due, the mortgagee took possession of the ship. When the freight later became payable the mortgagee sued the defendant for payment, and it was held that the defendant could not set off the excess advances. This was so notwithstanding that the advances were made before the defendant had notice of the mortgage, whereas ordinarily, if there are mutual debts in existence before notice of an assignment, the assignee takes subject to a right of set-off under the Statutes.87 However, the mortgagee's entitlement to freight in Tanner v Phillips was not based upon an assignment of a debt. Rather, the mortgagee claimed payment of freight as mortgagee in possession. The mortgagee became entitled in his own right to freight which the ship was in the course of earning. As Lord Cairns pointed out in Keith v Burrows,88 the right of a mortgagee in pos-session to freight in the course of being earned does not arise by virtue of any contract or antecedent right, but rather it is payable to the mortgagee once he or she goes into possession because the mortgagee is then regarded as the master or owner of the ship.89 The (p. 175) mortgagee's right depends on property, not on contract.90 Tanner v Phillips was not, there-fore, a case in which there were mutual debts between the mortgagor and the charterer which would have given rise to a set-off available against the mortgagee, were it not for a supposed principle that there may not be a set-off under the Statutes against a claim for freight. Rather, mutuality for the purpose of the Statutes was lacking in that, on the one hand, the charterer had a claim against the mortgagor for the excess advances and, on the other, the mortgagee in his own right was entitled to the freight from the charterer.91

5.22  The better view is that the freight rule, which precludes an equitable set-off or a common law defence of abatement against a claim for freight, does not extend to the Statutes of Set-off. In the case of the Statutes, the defence is statutory in origin, and the Statutes specifically allowed a set-off in the case of mutual debts. While the Statutes themselves have been repealed, the repealing legislation preserved the right of set-off conferred by the Statutes.92 The proper approach in the case of a statutory-based defence is to interpret the legislation,93 and there is nothing in the language of the Statutes to suggest that there is an exception in the case of an action for freight.

(5)  Bill of lading freight when the vessel is chartered

5.23  When a ship has been chartered, and the master signs bills of lading with third party shippers for the carriage of goods, the question whether the shipowner or the charterer is entitled to the bill of lading freight depends upon whether the master signed as agent for the shipowner or the charterer. If the charter is by demise the contract will be with the charterer, but in other cases the question will depend upon the documents and circum-stances of the particular case.94 When the contract is with the shipowner, the shipowner can sue the shipper for freight. If the charterer has nevertheless appointed an agent to collect the freight, and the shipowner gives notice to the agent before the freight has been received requiring the freight to be paid to it rather than the charterer, the shipowner can sue the agent for the freight as money had and received.95 Any expenses incurred by the agent in carrying out the charterer's instructions cannot be set off by the agent,96 since mutuality for the purpose of the Statutes of Set-off is lacking. If, on the other hand, the owner as the contracting party is paid the bill of lading freight, the owner is only entitled to retain an amount equal to the hire or freight then unpaid under the charterparty. The surplus must be paid to the charterer. Channell J decided this in Wehner v Dene Steam Shipping Co.97 The reason is not that the owner is liable to the charterer for the bill of lading freight received (p. 176) and the charterer is liable for hire or freight under the charterparty, and that these obligations are set off.98 It is not a case of cross-demands at all. Rather, the owner had contracted by the charterparty that it would be satisfied with the payment of the freight or hire specified in the charterparty for the use of the ship, and accordingly if the owner receives the bill of lading freight it is part of their contract that it will account for any surplus to the charterer.99

5.24  When the contract is with the charterer rather than the shipowner, the shipowner may have reserved a lien on sub-freights, entitling the shipowner to require payment to it of the bill of lading freight that is otherwise due to the charterer.100 The lien can be exercised only before the freight has been paid to the charterer or the charterer's agent.101 Moreover, it can be exercised only in respect of sums due to the shipowner at the time that the demand for payment is made pursuant to the lien.102 The lien does not confer a proprietary interest in the freight. It is merely a personal right to intercept freight before it is paid. It is analogous to a right of stoppage in transitu.103 The lien therefore would be subject to a right of set-off available to the shipper against the charterer, including under the Statutes in the case of mutual debts, since the set-off would have the effect that nothing would be paid to the extent of the set-off which could be intercepted.

B. Negotiable Instruments, Letters of Credit and Direct Debits

(1)  Negotiable instruments – equitable set-off

5.25  An unliquidated cross-demand generally cannot be employed as an equitable set-off in an action to enforce payment of a bill of exchange or other negotiable instrument.104 The House of Lords affirmed the principle in Nova (Jersey) Knit Ltd v Kammgarn Spinnerei GmbH,105 (p. 177) and it is also accepted in Australia106 and New Zealand.107 The principle applies whether the parties are immediate or remote,108 and whether the cross-demand arose out of the transaction in respect of which the instrument was given or, a fortiori, in any other way.109

5.26  The principle typically is invoked when a cheque is given as payment for the price of goods sold, and the vendor has breached a term in the contract which amounts to a partial failure of consideration110 so as to give rise to a claim against him or her for unliquidated damages. The breach does not provide the purchaser with a defence to an action by the vendor for payment of the cheque. This is sometimes explained on the ground that the cheque is a separate contract from the contract of sale, although it is not an essential requirement of an equitable set-off that the claim and the cross-claim should have originated in the same contract.111 The cheque has also been described as constituting a separate transaction from the sale,112 and indeed in the case of letters of credit in sale transactions this principle has been expressly incorporated in the Uniform Customs and Practice for Documentary (p. 178) Credits.113 But the most commonly accepted explanation is that the rule precluding a defence of equitable set-off is based upon a policy consideration, that a cheque or bill of exchange given as payment is considered to be equivalent to cash, albeit with payment deferred, and if an unliquidated cross-demand could provide a defence to an action on the instrument there would be a substantial inroad upon this commercial principle.114

Stay of execution

5.27  Stays of execution are subject to a similar restriction. A defendant in an application for summary judgment who asserts a counterclaim not amounting to a set-off ordinarily would not be granted leave to defend. On the other hand, the court in its discretion may order a stay of execution115 on the claimant's judgment until the defendant's crossaction has been tried,116 so that if the defendant succeeds in the cross-action execution would only issue for the balance of the two claims. However, a different practice applies when the claimant's claim is on a cheque or bill of exchange. The fact that the defendant in an action to enforce payment of a cheque asserts a counterclaim for unliquidated damages is not usually regarded as a ground for staying execution.117 This is not an inflexible principle, however, because it is said that the court may grant a stay if there are exceptional circumstances.118 But while the existence of this exception is generally recognized, the courts have been reluctant to recognize ‘exceptional circumstances’ which may detract from the principle that cheques and bills of exchange should be treated as cash.119 Indeed, in (p. 179) Nova (Jersey) Knit Ltd v Kammgarn Spinnerei GmbH120 Viscount Dilhorne said that it would ‘seldom, if ever’121 be right to allow a cross-claim to operate as a bar to execution, while Lord Russell of Killowen said that an unliquidated cross-demand is not available as a counterclaim in an action on a bill of exchange without referring to an exception of ‘exceptional circumstances’ in relation to a stay.122 Certainly it is not sufficient for a stay that there is a counterclaim which is likely to succeed,123 or that the claim on the cheque and the cross-action for unliquidated damages are part of the same transaction.124

5.28  A stay was ordered in Barclays Bank Ltd v Aschaffenburger Zellstoffwerke AG.125 A German acceptor of bills of exchange had a cross-claim against the English drawer that was the subject of an arbitration to be held in Copenhagen. Judgment was given against the acceptor on the bills, but the Court of Appeal stayed execution until the result of the arbitration was known.126 The reason for the stay is not altogether clear, although it appears from the judgment of Harman LJ127 that the German acceptor had argued that there may have been some difficulty in obtaining payment if it succeeded. The case received a mixed reception when the Court of Appeal later considered it in Cebora SNC v SIP (Industrial Products) Ltd.128 Buckley LJ said that it should be regarded as turning on its own particular facts. Stephenson LJ was more positive. He said that he was ‘not surprised’129 that a stay was granted in the circumstances of the case. Sir Eric Sachs, on the other hand, was critical of the decision. He noted that the report of the case, ‘perhaps wisely’,130 had not been included in the Law Reports or the All England Reports, and suggested that it was out of line with other authorities. Notwithstanding that criticism, a first instance judge ordered a stay in similar circumstances in Montecchi v Shimco (UK) Ltd.131 The plaintiff was an Italian businessman who had sold some goods to the defendant English company. The goods (p. 180) were paid for by bill of exchange drawn by the defendant. The defendant alleged that the goods were defective, and refused to honour the bill. The plaintiff then sought, and obtained, summary judgment for the amount of the bill, though execution was stayed until after the hearing of the counterclaim on condition that the defendant pay the amount of the judgment into a joint account or into court. In addition, the judge granted a Mareva injunction restraining the plaintiff from dealing in any way with or disposing of the proceeds of the judgment. Subsequently, however, the Court of Appeal upheld an appeal by the plaintiff against the order, principally on the ground that a Mareva injunction was inappropriate because there was no evidence that the plaintiff would attempt to avoid enforcement of a judgment obtained against him on the cross-action. In delivering the judgment of the court,132 Bridge LJ emphasized that it is not sufficient for a stay that the plaintiff suing on the bill, and against whom there is a cross-claim for damages, is foreign.133 This would particularly be the case if the claimant has a substantial business in its own country.134 On the other hand, Bridge LJ said that he should not be taken as saying that in no circumstances whatever could an injunction be granted to restrain a plaintiff from dealing with the fruits of a judgment in a case such as that before him.

5.29  The size of the paid up capital of a foreign company is regarded as of little significance,135 while Sir Eric Sachs in Cebora SNC v SIP (Industrial Products) Ltd136 rejected a submission that it is material to inquire into the virtues or defects of legal procedures in the country of a foreign plaintiff to which recourse may be necessary to enforce any judgment obtained on a cross-action. It has been suggested that a stay may be granted if there are ‘real grounds’ for supposing that the foreign plaintiff would not be likely to meet the counterclaim.137 If Sir Eric Sachs was correct in the Cebora case in saying that it is not relevant to inquire into defects of the legal procedures of the plaintiff's country, it is difficult to see what could give rise to ‘real grounds’ for supposing that the counterclaim would not be met other than issues relating to the solvency of the claimant. But that circumstance should be just as relevant in the case of an English plaintiff. In Continental Illinois National Bank and Trust Co of Chicago v Papanicolaou (The Fedora),138 Parker LJ suggested, in the context of a guarantee given in circumstances such that it was the equivalent of a letter of credit, to which principles similar to those applicable to bills of exchange apply,139 that it ‘might be’ that a stay would be granted if there was a counterclaim which was likely to succeed, coupled with cogent evidence that the holder of the guarantee, if paid, would be unable to meet a judgment on the counterclaim. Even in those circumstances, however, it is (p. 181) suggested that the courts would be reluctant to grant a stay. Thus, it has been held that it is not sufficient for a stay that the claimant on the cheque is a company in administration.140

Can ‘exceptional circumstances’ affect the entitlement to judgment?

5.30  The concept of exceptional circumstances is usually referred to in the context of a stay of execution, but there is authority suggesting that it might also be relevant in relation to the primary question, whether the holder of the instrument is entitled to judgment.141 In Barclays Bank v Aschaffenburger,142 Lord Denning said that, while the holder of a bill of exchange ordinarily is entitled to judgment notwithstanding a cross-claim for damages available against him or her, there may be exceptions to the rule,143 and similarly Salmon LJ indicated that the rule is not invariable.144 It is noticeable, however, that a stay of execution was granted to the defendant in that case, as opposed to a judgment recognizing that there was a defence to the extent of the cross-claim. Subsequently, in Brown, Shipley & Co Ltd v Alicia Hosiery Ltd,145 Lord Denning once again expressed the principle in terms that ‘in the ordinary way’ judgment should be given upon a bill notwithstanding a cross-claim, although the discussion later in his judgment concerned the possibility that the court in its discretion may grant a stay of execution, and indeed the availability of a stay was the issue in the case. In Saga of Bond Street Ltd v Avalon Promotions Ltd,146 the defendant against whom judgment had been given on a bill succeeded in an application to set aside the judgment because of a breach of contract by the plaintiff. In later cases, however, the courts have sought to distinguish the case (albeit unsatisfactorily).147 In view of the Nova (Jersey) Knit case,148 it is doubtful if it would now be followed.149

Circumstances which may provide a defence

5.31  The preceding discussion concerned the situation in which the unliquidated cross-demand either is unrelated to the transaction for which the bill of exchange or cheque constituted consideration or, if it arose out of the same transaction as the instrument, it merely gives rise to a case of partial failure of consideration. On the other hand, an acceptor of a bill of (p. 182) exchange has a defence to a claim brought against him or her by the drawer if his or her acceptance was procured by fraud, invalidity, or for a consideration which has totally failed.150 Therefore, if there has been a total failure of the consideration for which the bill was given,151 the acceptor has a defence.152 Similarly, fraud in relation to the transaction in respect of which the bill constituted payment or security may provide a defence to an action on the bill by the drawer,153 while it has been held in Australia that the principle under discussion does not apply where the cross-claim is to have the bill set aside or treated as a nullity pursuant to the Trade Practices Act 1974 (Cth), s. 87.154 In addition, in Australia the Full Court of the Federal Court has suggested that the rule might not apply where the bill was obtained as a result of conduct that was misleading or deceptive in breach of s. 52 of the Trade Practices Act.155

Debt on a negotiable instrument pleaded as a defence

5.32  The principle precluding an equitable set-off against a claim on a cheque or similar instrument should not apply in the converse situation in which the holder is seeking to employ the debt on the instrument in a set-off. In Williams v Davies156 Sir Lancelot Shadwell permitted a person who had obtained judgment on some promissory notes to set off the judgment against a damages liability to the maker of the notes. While the case has been criticized on the ground that the cross-demands were not sufficiently closely connected to give rise to an equitable set-off,157 it nevertheless suggests that a claim on a negotiable instrument may be employed defensively in a set-off.

(p. 183) (2)  Setting aside a statutory demand

5.33  Further, the existence of a cross-demand may provide a ground for setting aside a statutory demand served under the Insolvency Act 1986, s. 268 as a prelude to a bankruptcy petition based upon non-payment of a cheque. Pursuant to the Insolvency Rules 1986, r. 6.5(4)(a), the court may grant an application for an order setting aside a statutory demand if the debtor appears to have a ‘counterclaim, set-off or cross demand’ which equals or exceeds the amount of the debt. ‘Cross-demand’ has a wider meaning than the technical terms ‘set-off’ and ‘counterclaim’.158 The fact that the damages cross-claim would not have given rise to a defence to a claim on the cheque, and would not have constituted grounds for a stay of execution on a judgment on the cheque, does not mean that it is not a cross-demand for the purpose of r. 6.5(4)(a).159 A similar principle applies in the case of a petition to wind up a company for failure to pay a cheque or other instrument. If the company has a genuine and serious cross-claim in an amount which exceeds the debt to the petitioner, the petition may be dismissed or stayed unless there are special circumstances which make it inappropriate to do so.160

(3)  Insolvency set-off

5.34  Similarly, a claim on a cheque or other instrument may be the subject of a mandatory set-off under the insolvency legislation in the event of a bankruptcy or a liquidation of the party liable on the instrument, provided that the other requirements of the insolvency set-off section are satisfied.161

(4)  Negotiable instruments – Statutes of Set-off

5.35  While it is now settled that an equitable set-off based upon a cross-claim for damages is not available (save possibly in exceptional circumstances) as a defence to an action on a bill of exchange or other negotiable instrument, conflicting views have been expressed in relation to the availability of a set-off under the Statutes of Set-off in the case of mutual debts.

5.36  It is sometimes suggested that the principle which precludes an equitable set-off in respect of an unliquidated cross-demand also applies to the Statutes, so that generally the drawer of a cheque or the acceptor of a bill being sued for payment cannot raise as a defence an independent debt owing by the holder. There is one situation in which it is recognized that (p. 184) a set-off may arise under the Statutes, and that is when a cheque or other instrument is given as payment for goods sold or services performed and there is a liquidated cross-demand arising from a partial failure of consideration.162 That situation is referred to below.163 But if the cross-debt is not connected in that way, it has been suggested that it cannot be set off.164 This view is said to be supported by a comment by Sir Eric Sachs in Cebora SNC v SIP (Industrial Products) Ltd,165 which has been referred to by the courts on other occasions with evident approval.166 Sir Eric Sachs said that the courts will refuse to regard as a defence to a claim on a bill of exchange ‘any set off, legal or equitable, or any counterclaim, whether arising on the particular transaction upon which the bill of exchange came into existence, or, a fortiori, arising in any other way’.167 There are four points to note in relation to this comment. The first is that, in so far as it extended to legal set-offs, it was obiter. The second is that the reference to ‘legal’ set-off may have had in contemplation the common law cases which have held that the principle of abatement168 does not apply when the price had been paid by way of bill of exchange, as opposed to the form of set-off conferred by the Statutes of Set-off in the case of mutual debts.169 The third is that the decision of the House of Lords in Nova (Jersey) Knit Ltd v Kammgarn Spinnerei GmbH170 does not require the conclusion that the Statutes have a limited operation in the case of bills of exchange. The Nova (Jersey) Knit case concerned equitable set-off, not the statutory defence.171 The fourth point is that, if Sir Eric Sachs did intend to refer to the Statutes, it is not an accurate statement of the traditionally accepted position. The right of set-off in the (p. 185) case of mutual debts was not developed as an equitable or a common law doctrine, but rather it is statutory in origin. In the case of a defence conferred by statute the proper approach is to examine the words of the relevant legislation,172 and the Statutes of Set-off simply stipulated that a set-off could occur in the case of mutual debts. There is nothing in them to suggest that they were not intended to apply when the plaintiff is suing on a cheque or other instrument.

5.37  At least since the latter half of the eighteenth century the courts have recognized that an independent cross-debt may be set off under the Statutes against a claim on a negotiable instrument.173 In Baskerville v Brown174 Lord Mansfield accepted that Baskerville could have pleaded the debt owing to him as a defence in Brown's action against him on the promissory note, and Lord Kenyon allowed a set-off in a similar situation in Lechmere v Hawkins.175 In 1812 the Court of King's Bench in Wake v Tinkler176 did not dispute that a set-off under the Statutes was available in principle against a claim on a promissory note, although a set-off was denied on another ground. The availability of a set-off is also supported by the line of cases which developed in the middle of the nineteenth century dealing with overdue bills and promissory notes.177 The cases established the proposition that, when the indorsee of an overdue bill sues the acceptor, the indorsee does not take subject to a set-off under the Statutes in respect of an unconnected cross-debt owing to the acceptor by an earlier holder.178 Nevertheless, it was assumed that a set-off would have been available if instead the earlier holder had sued. For example, in Burrough v Moss179 the defendant gave a promissory note to a married woman. According to the then applicable law, this entitled her husband (one Fearn) to treat it as his own property. Fearn himself was indebted to the defendant on an unrelated matter. After the note became due, Fearn indorsed it to the plaintiff. When the plaintiff sued the defendant on the note, the defendant sought to set off Fearn's indebtedness to him. It was held that a set-off was not available against the plaintiff as indorsee. On the other hand, Bayley J considered that one of the consequences of Fearn treating the note as his own ‘would be, to let in by way of set-off to any claim by him, any debts due from him’,180 and he said that: ‘As to the other sum of (p. 186) 28l due from Fearn alone … it might have been set off had Fearn sued on the note.’181 That also accords with views expressed by counsel for both parties during argument. Oulds v Harrison182 was a similar case. In the course of giving the judgment of the Court of Exchequer, Parke B asked:183

[W]hat is the effect of an indorsement of an overdue bill under the circumstances mentioned in the plea? These though inaccurately stated, we think, amount to an averment, that both the indorser and indorsee, knowing that there was a debt due to the defendant, which would be set off if the action should be brought by the indorser against the defendant, in order to defeat that set-off, and fraudulently, so far as that was a fraud but no further, agreed that the bill should be indorsed, and it was therefore indorsed, without value, to the plaintiff.

It was held that the circumstances referred to did not prevent the application of the principle that an indorsee of an overdue note takes free from rights of set-off available against the indorser. Parke B nevertheless recognized that, if the indorser instead had been the party suing on the bill, he could have been met by a set-off under the Statutes in respect of the debt that he owed to the acceptor. Nor is there anything in the report to suggest that the indorser's debt to the acceptor was connected with the transaction in respect of which the bill was given. These cases were decided after some of the early cases which had established that a claim on a bill of exchange given as payment of the price of goods sold and delivered cannot be met by a defence based upon a cross-claim for damages for a defect in the goods,184 and it may be assumed that the judges were aware of those earlier cases.

5.38  There are instances in Victoria in which the courts have held that a debt arising otherwise than as a result of a partial failure of consideration could be set off under the Statutes against a claim on a negotiable instrument. One such case is Ingleton v Coates,185 a decision of Madden CJ, in which the debt sought to be set off originated in a loan made to the person to whom the promissory note being sued upon had been indorsed, the debt on the loan having been assigned to the maker of the promissory note. In Mobil Oil Australia Ltd v Caulfield Tyre Service Pty Ltd186 Young CJ, having quoted the passage from the judgment of Sir Eric Sachs in the Cebora case referred to above, suggested that the decision in Ingleton v Coates to allow the maker leave to defend may need to be reconsidered,187 though the better view is that it was correct. Two other Victorian cases support that view. The first is Nisbet v Cox,188 which concerned a set of bills. The report only takes the form of a short note, but it appears to have been accepted that a set-off under the Statutes was available once the last bill became due. The report simply states that a debt was alleged to be due from the plaintiff to the defendant acceptor. The nature of the debt is not mentioned, and presumably it was (p. 187) not regarded as significant. The second case is Woodroffe v Moss.189 The defendant in an action brought against him on a cheque pleaded by way of defence that the plaintiffs had been his agents for the sale of some goods, and in breach of their duty as agents themselves purchased the goods and sold them on their own account at enhanced prices without accounting for the difference in price. The Full Court of the Victorian Supreme Court held that this could be pleaded as a defence of set-off. It has been suggested that the case turned on the circumstance that it involved delinquency by a fiduciary.190 However, that point was not emphasized in argument or in any of the judgments. The whole discussion centred on whether the claim against the plaintiff was liquidated. It was held that it was. Therefore, a set-off was allowed under the Statutes.

5.39  Further, in Hongkong and Shanghai Banking Corporation v Kloeckner & Co AG191 Hirst J accepted as ‘well settled’ a general statement by counsel to the effect that a set-off is permissible against a claim on a bill of exchange when the cross-claim is liquidated though not when it is unliquidated.192

5.40  The case of freight payable to a shipowner provides an analogy.193 The position in relation to freight is similar to that applicable to bills of exchange, in that neither equitable set-off nor the common law defence of abatement may be asserted in answer to a claim for freight. But there is also authority in that context for the proposition that the principle which precludes those defences does not affect the application of the Statutes of Set-off when the case involves mutual debts.194

5.41  Nevertheless, recent comments in the Court of Appeal support the more restrictive view. In Safa Ltd v Banque du Caire195 Waller LJ, in a judgment with which Lady Justice Hale and Lord Justice Schiemann agreed, said in the context of bills of exchange that set-off is ‘only available between immediate parties in relation to liquidated sums’.196 This was not expressly limited to the case of a partial failure of consideration,197 although the discussion earlier in the judgment198 suggests that he also had in mind that limitation. Thus, Mance LJ, in delivering the judgment of the Court of Appeal199 in Solo Industries UK Ltd v Canara Bank,200 later referred to Waller LJ in Safa as having cited: ‘the principles governing bills of (p. 188) exchange, according to which set-off is not admissible, other than between immediate parties in cases of partial failure of consideration when the amount involved is both ascertained and liquidated …’ However, the justification for restricting the defence to immediate parties and to cases of partial failure of consideration remains unclear. When a bill of exchange is issued by reference to an underlying transaction,201 and there has been a partial failure of consideration where the amount involved is liquidated and ascertained,202 the case is one of mutual debts, and therefore the Statutes of Set-off prima facie apply. But the Statutes do not require any connection between the debts the subject of the set-off,203 and so the connection or otherwise between the debt sought to be set off and the transaction that gave rise to the instrument should not be relevant to the question whether the Statutes apply. For the same reason, it should not matter whether the parties are immediate or remote. The comments in the Safa and Solo Industries cases were obiter, and the point was not subjected to detailed analysis. In view of the earlier authorities suggesting that the defence is not so restricted, and in view of the language of the Statutes of Set-off themselves, those comments should not be regarded as having settled the issue.

(5)  Statutes of Set-off – set-off against a subsequent holder

5.42  If, as suggested, a set-off under the Statutes of Set-off may be asserted against a claim on a bill of exchange or other negotiable instrument, the further question may arise whether a subsequent holder of a bill takes subject to a right of set-off that would have been available against the prior holder under the Statutes if the prior holder had sued on the bill. If the subsequent holder is a holder in due course, he or she takes free from personal defences between prior parties, which include rights of set-off. This is a longstanding principle which has been codified in the Bills of Exchange Act 1882, s. 38(2). On the other hand, s. 38(2) does not state what happens when the subsequent holder is not a holder in due course, and opinions differ amongst text-writers as to whether a subsequent holder in such a case is bound by rights of set-off between prior parties.204 The issue is dealt with later.205 The better view is that the subsequent holder is not bound, even if he or she is a mere holder who has not given value.

(6)  Letters of credit

5.43  Letters of credit are generally treated in a similar manner to cheques and bills of exchange. An irrevocable letter of credit is regarded in mercantile practice as being the equivalent of (p. 189) cash in hand.206 In the absence of fraud, it must be paid regardless of any cross-claim available to the person at whose request the letter was issued against the holder, even if the cross-claim arose out of the transaction on which the letter was based.207 This is also the case for performance bonds and bank guarantees when they are given in circumstances such that they are equivalent to letters of credit.208

5.44  A transaction involving a letter of credit typically differs from a transaction in which a cheque or bill of exchange is given. A cheque or a bill is often given as payment for the price of goods or services. In that situation the person liable on the instrument is commonly a party to the transaction which gave rise to the instrument. A letter of credit also may be given in order to effect payment to the seller of goods, but it would be rare for the issuer of the letter of credit, typically a bank, to be involved in the underlying transaction. But what if, in a rare case, the bank is involved in the transaction?

5.45  In Power Curber International Ltd v National Bank of Kuwait SAK,209 goods had been sold on terms that they were to be paid for by letter of credit issued by the defendant bank in favour of the seller. In the course of his judgment Lord Denning commented that: ‘A letter of credit is like a bill of exchange given for the price of goods. It ranks as cash and must be honoured. No set-off or counterclaim is allowed to detract from it …’210 Later, Hirst J, in Hongkong and Shanghai Banking Corporation v Kloeckner & Co AG,211 said of that statement that it must be interpreted as meaning a set-off or counterclaim by the buyer against the seller, and not one by the bank against the seller, the latter situation not being under consideration in the Power Curber case. In the Kloeckner case a bank had issued a standby letter of credit in relation to transactions in which the bank itself was involved. The transactions involved back-to-back sales, and the beneficiary of the letter of credit in turn had given a payment undertaking to the bank. One of the questions was whether the bank could set off its claim on the payment undertaking against its liability on the letter of credit. Hirst J said that the case before him had two striking features. The first was that the bank's claim arose out of the banking transactions which gave rise to the letter of credit, and the second was that the set-off in issue was a ‘liquidated set-off’. In those circumstances, he concluded that the case in favour of a set-off was overwhelming.

(p. 190) 5.46  Subsequently, the issue received the attention of the Court of Appeal in Safa Ltd v Banque du Caire.212 A bank had given a letter of credit to an insurance broker, the purpose of the letter of credit being to cover the premium payable to an insurance company which was to provide a financial insurance guarantee to the bank in relation to a facility to be provided by the bank to a third party. The broker made a claim on the letter of credit which the bank alleged was fraudulent. After a review of the authorities, including the Kloeckner case, Waller LJ formulated a number of propositions:213

  1. 1. The principle that letters of credit must be treated as cash is an important one, and must be maintained.

  2. 2. It is however unusual for a bank which has opened a letter of credit to be involved in the related transaction to the extent this bank was.

  3. 3. When a bank is involved in the related transaction it may be unjust for that bank to be forced to pay on a summary judgment where it has a real prospect of succeeding by reference to a claim on the underlying transaction, and particularly if that claim is a liquidated claim, the Court should not give summary judgment either because a set-off has a reasonable prospect of success or because there is a compelling reason to have a trial of the letter of credit issue.

  4. 4. If a bank can establish a claim with a real prospect of success, either that the demand was fraudulent even if it had no clear evidence of fraud at the time of demand, or that there was a misrepresentation by the beneficiary directed at persuading the bank to enter into the letter of credit, it may also be unjust to enter summary judgment against the bank either because the bank has a reasonable prospect of succeeding in a defence of set-off or because there is a compelling reason for a trial of the letter of credit issue.

In his third proposition, dealing with the situation in which the bank is involved in the underlying transaction, Waller LJ referred to a case in which the bank's claim is liquidated. But he seems to have regarded that factor as an additional reason for refusing summary judgment to the beneficiary of the letter of credit, as opposed to constituting a necessary element. He said that a set-off may be available, and the court should not therefore give summary judgment, if the bank has a claim on the underlying transaction which has a real prospect of success,214 and he continued that this particularly should be the case if the bank's claim is liquidated. This leaves open the possibility that the bank's claim in some cases may be unliquidated, though presumably subject to a requirement that the cross-claims must be sufficiently connected to give rise to an equitable set-off. Later, Mance LJ, in Solo Industries UK Ltd v Canara Bank,215 after referring to the propositions in Safa, commented that he agreed that: ‘special considerations arise in circumstances such as those in the Safa case itself, where the beneficiary and bank are both intimately involved in a wider underlying transaction.’ In the Safa case, Waller LJ said that if the bank in that case paid under the letter of credit it would have been entitled in the circumstances to immediate reimbursement by the broker. The claim would be for a liquidated (p. 191) sum, and he said that the connection between the claims would be such that a set-off would be allowed if the bank's claim were established.216 Any such set-off would not have been based on the Statutes of Set-off. For the Statutes to apply, there must be mutual debts. However, the bank's right to reimbursement would only have crystallized into a debt after the bank had paid under the letter of credit. But at that point there would no longer have been a debt owing by the bank. There would not therefore have been mutual debts, so that the set-off could not have been based on the Statutes. It could only have been an equitable set-off arising from the closeness of the connection of the claims, and equity has never regarded the distinction been liquidated and unliquidated claims as critical to the question whether the equitable defence should apply.

5.47  This view would give rise to a problem, however. If a bank which has issued a letter of credit is entitled to assert a set-off when it has a claim against the beneficiary arising out of the underlying transaction in respect of which the letter of credit was given, so as to justify refusing summary judgment to the beneficiary of the letter, and if that may apply also when the bank's claim is unliquidated, the letter of credit cases would depart from the principle applicable in the case of cheques and bills of exchange. In the case of a cheque or a bill of exchange given as payment of the price of goods sold or services performed, it is established that the fact that the drawer of the cheque or the acceptor of the bill may have a damages claim against the other party arising out of the underlying transaction is not sufficient to give rise to a set-off.217 The generality of the third proposition in the Safa case, therefore, may require reconsideration. In the Safa case, there were allegations of fraud. Fraud was the subject of the fourth proposition put forward by Waller LJ, but, as Mance LJ later remarked, this appears to have been an independent point and it is not clear that the case was decided by reference to it.218 In order to preserve the analogy with bills of exchange,219 the Safa case should be regarded as turning on its peculiar facts, in particular the allegation of fraud. Furthermore, in so far as the third proposition is to be regarded as an independent principle, it should be confined to liquidated claims, so as to accommodate set-off under the Statutes of Set-off. This reflects the circumstances in issue in the Kloeckner case, though in the case of the Statutes it is not clear why the availability of the defence should be limited to a claim arising out of the underlying transaction.220

5.48  In his fourth point in the Safa case, Waller LJ referred to a fraudulent claim on a letter of credit and to a situation in which there was misrepresentation inducing the bank to enter into the letter of credit. In both cases he suggested that it would suffice in a summary judgment application for the bank to establish a claim with a real prospect of success. (p. 192) Subsequently, the Court of Appeal in Solo Industries UK Ltd v Canara Bank221 declined to accept that view. Mance LJ, in delivering the judgment of the Court, drew a distinction between fraud going to the validity of the instrument itself and a fraudulent demand under the instrument. In the former case he said that the bank may be granted leave to defend in a summary judgment application if it can show that it has a real prospect of successfully defending the claim.222 A higher standard applies, however, in the case of a fraudulent demand. If the bank paid under a fraudulent demand, it would have a cause of action against the beneficiary for fraudulent misrepresentation.223 That cause of action may provide a defence to the bank, but in order to justify leave to defend the fraud must be established, or clear. It is not sufficient that the defence has a real prospect of success. Short of established fraud, a bank would not normally be allowed to raise an alleged impropriety affecting the demand as a defence.

(7)  Direct debit

5.49  In Esso Petroleum Co Ltd v Milton,224 the Court of Appeal held that the principle applicable to cheques extends also to a direct debit arrangement. The case concerned a purchaser of goods who had authorized payment by way of a direct debit to his bank account, but cancelled the bank's mandate to debit the account after the goods were delivered. The majority (Thorpe LJ and Sir John Balcombe, Simon Brown LJ dissenting on this point) considered that the vendor was entitled to summary judgment for the amount otherwise admitted to be due, and the purchaser was not granted leave to defend on the basis of an unliquidated damages cross-claim. This conclusion was justified by reference to a perception that in modern commercial practice a direct debit is treated in the same way as payment by cheque and, as such, as being the equivalent of cash.225 There is nevertheless much force in Professor Tettenborn's criticism of the decision,226 which expands on the dissenting judgment of Simon Brown LJ on this issue.227 A direct debit arrangement in truth differs in an important respect from payment by cheque or bill of exchange. When a cheque is given as payment for goods or services supplied, the vendor does not sue on the underlying contract for the price, but on the cheque. On the other hand, when a direct debit arrangement is cancelled, the vendor's action is for the price pursuant to the original contract. Unlike a cheque, a direct debit arrangement does not confer any rights upon the vendor which are independent of the original contract. Subsequently, a differently constituted Court of Appeal in Courage Ltd v Crehan228 followed the Milton case in the context of a commercial lease. In giving the court's judgment, Morritt LJ said that he was bound by the Milton case, and he declined to express a view on the merits of the decision.229

(p. 193) C. Building and Construction Contracts

(1)  General principle

5.50  A cross-claim for damages for delay,230 or bad workmanship, or failure to complete is capable in principle231 of being employed in a set-off against an amount due for work performed under a building contract.232 At one time it was thought that a set-off was not available in cases in which the price was to be paid by instalment on the certificate of an architect or engineer, or some other such person. In a series of cases, commencing in 1971 with the Court of Appeal decision in Dawnays Ltd v F. G. Minter Ltd,233 it was held that a certificate issued in respect of the work done to date by a contractor or a subcontractor under a building contract was to be regarded as equivalent to cash, and therefore the debt due under the certificate had to be paid save only for deductions permitted by the contract. A claim on the certificate by the contractor against the employer, or by a subcontractor against the contractor, could not be met by a set-off or a counterclaim in respect of an unliquidated cross-demand. Nor would the existence of the unliquidated cross-demand provide a ground for a stay of an action on the certificate pending arbitration. Provisions in the contract permitting certain deductions or set-offs were interpreted as referring only to liquidated ascertained sums which were established or admitted as being due.234 Unliquidated crossdemands had to be prosecuted separately. The impetus for these decisions was cash flow. It was said that, if the contractor or subcontractor failed to receive the money stipulated in the certificate, it might not be in a position to complete the contract works. The contracts in question, therefore, were construed so as to give effect to the presumed intention of the (p. 194) parties that cash flow should be preserved.235 However, Dawnays v Minter and the cases following it were the subject of trenchant criticism by one commentator,236 and it was overruled some two years later by the House of Lords in Gilbert-Ash (Northern) Ltd v Modern Engineering (Bristol) Ltd.237 The House of Lords held that there is no presumption in building cases in which the price is to be paid by instalment on certificate that the parties intend that the ordinary defences of set-off and abatement238 should not apply. The perceived desirability of facilitating cash flow was not considered to be something unique to the building industry, and it was not regarded as a sufficient justification for ousting those rights.239

(2)  Housing Grants, Construction and Regeneration Act 1996

5.51  The right to assert a defence of set-off or abatement in this context is now subject to Part II of the Housing Grants, Construction and Regeneration Act 1996.

5.52  Part II of the Act deals with payment and adjudication under a ‘construction contract’.240 It has a number of aspects. In cases where it is agreed that the duration of the contract is to be 45 days or more, s. 109 establishes a general entitlement to payment by instalments, stage payments or other periodic payments for work done under the contract. In the event of a dispute arising under a construction contract, s. 108 provides for adjudication. The decision of the adjudicator is to be binding until the dispute is finally determined by legal (p. 195) proceedings, arbitration or agreement. Pursuant to s. 110, the contract is required to provide a mechanism for determining what payments are due under the contract, and also for the giving of a notice specifying the amount of the payment made or proposed to be made and the basis on which that amount was calculated.241 Section 111 is of considerable importance. It precludes a party to a construction contract from withholding payment after the final date for payment of a sum due under the contract unless that party has given an effective notice of intention to withhold payment pursuant to the Act.242 If a timeous notice is not given under s. 111, summary judgment may be sought for the amount due.243 The purpose of the legislation has been said to be to introduce a speedy mechanism for settling disputes in construction contracts on a provisional interim basis and requiring the decisions of adjudicators to be enforced pending the final determination of disputes.244

5.53  Section 111 has been held to extend to an asserted right to withhold payment on account of equitable set-off245 or abatement,246 where the sum claimed is otherwise payable in accordance with the terms of the contract.247 On one view, this might be thought a surprising conclusion. For s. 111(1) to apply there must be a ‘sum due’, whereas if an equitable set-off is available there is nothing due, so far as equity is concerned, to the extent of the set-off.248 Similarly, nothing is due when there is a defence of abatement. Nevertheless, the adoption of that analysis to a considerable extent would denude the provision of effect, and the courts are likely to adhere to the view that s. 111 may apply when defences of equitable set-off and abatement are in issue.249 The intention is that valid adjudicators’ decisions are to be enforced without set-off.250 Set-offs should be raised in the adjudication, where the adjudicator may allow or disallow them, as opposed to the losing party raising set-offs in the enforcement proceedings.

(p. 196) 5.54  On the other hand, it is only a withholding from a sum which is due ‘under the contract’ which attracts the requirement of a notice under s. 111. This requires an identification of the amount payable under the terms of the contract. In considering this point, the courts have drawn a distinction between, on the one hand, a case where the circumstance which makes a sum due under the contract is the fact of the work having been done, and, on the other, the situation in which the contract provides that the amount payable is the amount certified by an architect or other such person. In the former case, the amount due under the contract is the value of the work done. A dispute about whether the work in respect of which the claim was made had been done, or about whether it was properly measured or valued, goes to the initial question whether the sum claimed indeed is due under the contract, and a withholding notice is unnecessary in respect of that dispute.251 But where the contract requires payment of an amount certified, it is not the actual work done which defines the sum payable but the amount in the certificate. Any withholding from that amount must be the subject of a notice under s. 111.252

5.55  As Jacob LJ observed in Rupert Morgan Building Services (LLC) Ltd v Jervis,253 s. 111 is a provision about cash flow. It does not purport to make a payment certificate conclusive, and it does not preclude a person who has paid from subsequently showing that he or she has overpaid. If the overpayment was made on an interim certificate, the matter can be put right in subsequent certificates. Otherwise, it can be raised by way of adjudication254 or, if necessary, arbitration or legal proceedings.255 However, as Jacob LJ also observed in the Rupert Morgan case,256 the statutory procedure has the disadvantage that a person who has overpaid a claimant is at risk of the claimant's insolvency. The claimant may not be able to repay the amount of an overpayment made pursuant to a certificate at a later date. Notwithstanding that risk, if a claimant who has obtained an adjudication in its favour is insolvent, the fact of the insolvency is not regarded as a sufficient ground for refusing an application for summary judgment for the amount of the adjudication,257 though (depending on the circumstances) it could provide a ground for a stay of enforcement of the judgment pending trial of the counterclaim.258 A stay might be refused, however, if the claimant was in the same or a similar financial position when the contract was (p. 197) entered into,259 or if the claimant's financial position is due, either wholly or in significant part, to the defendant's failure to pay the sum awarded by the adjudicator.260

5.56  The position is different if the claimant who succeeded in the adjudication is bankrupt or is in liquidation.261 In either of those cases, the cross-claims between the parties will be the subject of an automatic set-off pursuant to the mutual credit provision in the insolvency legislation.262 Under the insolvency set-off provision, an account is deemed to have been taken upon the occurrence of the bankruptcy or the liquidation so that, as between the insolvent and the other party, there is only a single claim for the balance. In those circumstances, Chadwick LJ in Bouygues (UK) Ltd v Dahl-Jensen (UK) Ltd263 considered that summary judgment should not be given on a claim arising out of an adjudication which is merely provisional.264

5.57  In a number of cases the question has arisen whether a claim for liquidated and ascertained damages under a contract can be set off against sums due pursuant to an adjudicator's decision. In Balfour Beatty Construction v Serco Ltd265 Jackson J (as he then was) derived the following principles from the authorities:

  1. (a)  Where it follows logically from an adjudicator's decision that the employer is entitled to recover a specific sum by way of liquidated and ascertained damages, then the employer may set off that sum against monies payable to the contractor pursuant to the adjudicator's decision, provided that the employer has given proper notice (in so far as required).

  2. (p. 198) (b)  Where the entitlement to liquidated and ascertained damages has not been determined either expressly or impliedly by the adjudicator's decision, then the question whether the employer is entitled to set off liquidated and ascertained damages against sums awarded by the adjudicator will depend upon the terms of the contract and the circumstances of the case.

The allowance of a set-off in this situation has been described as a ‘particular exception’266 which does not give a wider power to set off sums generally against an adjudicator's decision.267

(3)  ‘Security of payment’ legislation in Australia

5.58  In New South Wales, the Building and Construction Industry Security of Payment Act 1999 serves a similar function to the Housing Industry, Construction and Regeneration Act. Similar (but not identical) legislation exists in other Australian jurisdictions.268 The discussion below relates to the New South Wales Act, which was the first such legislation in Australia.

5.59  Briefly, the scheme of the New South Wales legislation is as follows. Section 8 provides that a person who has undertaken to carry out construction work under a construction contract is entitled to progress payments. Pursuant to s. 13, a person who is entitled to a progress payment (the ‘claimant’) may serve a payment claim on the person liable to make the payment (the ‘respondent’). The respondent may reply to the claim by providing a payment schedule to the claimant which sets out reasons for withholding payment. If the respondent does not provide a payment schedule to the claimant, the respondent becomes liable to pay the claimed amount.269 In proceedings by the claimant to recover the claimed amount, s. 15(4)(b) provides that the respondent is not entitled: (i) to bring any crossclaim against the claimant; or (ii) to raise any defence in relation to matters arising under the construction contract. Alternatively, if the respondent serves a payment schedule in (p. 199) response to the payment claim which provides for a lesser amount than the amount indicated in the payment claim, the claimant may apply for adjudication under s. 17.270 If the respondent fails to pay the adjudicated amount, the claimant may obtain an adjudication certificate which may be filed as a judgment debt in a court of competent jurisdiction.271 The respondent may apply to have the judgment set aside. In those proceedings, however, s. 25(4) provides that the respondent is not entitled to challenge the adjudicator's determination. Moreover, the respondent is subject to constraints similar to those set out in s. 15(4)(b) (above), in that the respondent cannot bring any cross-claim against the claimant or raise any defence in relation to matters arising under the construction contract.272 Section 32 emphasizes the provisional nature of the procedure under the Act. It provides that the procedure does not affect any right that a party to a construction contract may have under the contract or may have apart from the Act in respect of anything done or omitted to be done under the contract.

5.60  A curious aspect of s. 15(4)(b) (above) is that, while the prohibition in relation to crossclaims is absolute, the prohibition in relation to raising a defence is limited to matters arising under the construction contract.273 This would pick up an equitable defence of set-off arising from defects or delay. But defences which are not in relation to matters arising under the contract are not precluded. In Bitannia Pty Ltd v Parkline Constructions Pty Ltd,274 the New South Wales Court of Appeal accepted that s. 15(4)(b) did not preclude a defence based upon misleading or deceptive conduct contrary to the Trade Practices Act 1974 (Cth), s. 52, in circumstances where an essential element of the claimant's entitlement to judgment (the failure of the respondent to provide a payment schedule) had been brought about by the claimant's misleading conduct. The defence was not prohibited by s. 15(4)(b) (ii) because it did not arise ‘under the construction contract’, and nor was it in relation to a matter arising under the contract.275 Hodgson JA justified the defence in that case on the availability of an injunction under the Trade Practices Act,276 but both he and Basten JA accepted that a defence of equitable set-off could apply where damages are sought under the Trade Practices Act, ss. 82 or 87.277

(p. 200) 5.61  Similar to the view adopted in England in the Bouygues case,278 courts in New South Wales have said that the Building and Construction Industry Security of Payment Act 1999 (NSW) does not preclude a set-off in the liquidation of a contractor pursuant to the Corporations Act 1981 (Cth), s. 553C (or under a deed of company arrangement executed by the contractor which incorporates s. 553C).279 In particular, Young CJ in Eq held in Brodyn Pty Ltd v Dasein Constructions Pty Ltd280 that s. 25 of the New South Wales Act did not preclude a set-off where an adjudication certificate had been filed as a judgment debt. This view would seem correct. As a result of the operation of s. 553C, a set-off will have occurred automatically at the date of the liquidation (or the date of the deed),281 so that to the extent of the set-off the amount owing to the contractor under the contract will have been paid.282 Later cases support this view.283

(4)  Excluding or limiting equitable set-off and abatement by contract

5.62  In building and construction contracts, a cross-claim for damages for defective workmanship can give rise not only to a set-off in equity but also to the common law defence of abatement.284 Therefore, if in a particular case s. 111 of the Housing Grants, Construction and Regeneration Act 1996 (above) does not apply,285 and it is intended that the contract sum is to be paid in full without any deduction for cross-claims arising out of defects, or that a defined procedure should be followed before any such deduction is permitted, care must be taken to negative or limit both defences. In Acsim (Southern) Ltd v Danish Contracting and Development Co Ltd286 the contract provided that Danish Contracting (‘Dancon’) could set off against any moneys otherwise due to Acsim as contractor the amount of any cross-claim which Dancon had for loss suffered as a result of a breach by Acsim, but only if the cross-claim was quantified and notified to Acsim within a specified time limit. The contract went on to provide that this fully set out the rights of the parties in respect of set-off. The Court of Appeal considered that the contract was effective to prevent (p. 201) a cross-claim for damages for bad workmanship that was quantified outside the required period from being employed as an equitable set-off. On the other hand, there were not sufficiently clear and express words to exclude the common law defence of abatement.287 Pursuant to the common law principle, the subject of the cross-claim was not being raised as a set-off as such. Rather, Dancon was defending itself by showing that, by reason of Acsim's breaches of contract, the value of the work done was less than the sum claimed. That defence was not affected by the contract.

5.63  The question whether the parties have agreed to exclude the defences is one of interpretation of the contract, and in that regard it is often said that the intention to exclude must be evidenced by clear express words, or at least there must be a clear implication in the contract that they are not to apply. Contracting out of set-off is considered in greater detail later.288

D. Contracts of Employment

(1)  Failure to work

5.64  An employee may have refused or failed to work in accordance with the contract of employment for part of a period in respect of which a claim for wages is made. The analysis in such a case is not that the employee has a prima facie entitlement to wages for that period but subject to a set-off available to the employer, to the extent of a proportion of the wages equal to the proportion of the period during which the employee failed to work.289 Rather, the employee fails at the first hurdle, in that the employee is not entitled to wages to the extent that he or she was not ready and willing to perform the services required by the contract.290

(2)  Claim for damages

5.65  Alternatively, an employer may have suffered loss as a result of the actions of an employee which give rise to a claim in damages against the employee. There is authority supporting the availability of an equitable set-off in that circumstance,291 although it has been said that the principles upon which an equitable set-off can be effective in a claim for wages are (p. 202) extremely limited, and that it would depend upon a careful analysis of the nature of the breach relative to the nature of the employee's contractual claim.292 The Employment Rights Act 1996, s. 13 prohibits an employer from making a ‘deduction’ from wages except in certain defined circumstances,293 but on one view this would not preclude an equitable set-off. Equitable set-off is a substantive defence.294 If the defence is available, it would not be a case of the employer making a deduction from wages to which the employee was entitled. Rather, the set-off would render it unconscionable for the employee to regard the employer as being liable to pay wages to the extent of the cross-claim,295 so as to impugn the employee's right to claim wages. In other contexts, a stipulation in a contract that a payment is to be made ‘without any deduction’ has been held not to be effective to exclude an equitable set-off.296 Nevertheless, this would be contrary to the evident legislative intent in enacting a provision such as s. 13, and in Australia it has been doubted whether an equitable set-off is available against a claim for wages in the face of a statute to that effect.297

(3)  Insolvency set-off

5.66  In any event, if the employer becomes bankrupt or goes into liquidation,298 cross-demands between the employer and the employee, including a cross-demand in relation to wages, prima facie would come within the ambit of the insolvency set-off section.299 The prevail-ing view of insolvency set-off is that it is automatic and self-executing,300 and, provided that the requirements of the section are satisfied, a set-off should occur at the date of the bank-ruptcy or liquidation by force of law.301 It would not be a case of the employer making a deduction from wages.

(p. 203) E. Landlord and Tenant

(1)  Equitable set-off

5.67  At one time it was thought that special considerations applied to a landlord's claim for rent, in that a tenant could not raise an unliquidated cross-claim against the landlord, for example for breach of an obligation to repair, as a defence to an action by the landlord against the tenant for payment of arrears of rent.302 Whether indeed that view ever had a solid foundation in equity may be doubted. Thus, in Beasley v Darcy303 a landlord had served the tenant with an ejectment for non-payment of rent and duly recovered possession, but the tenant obtained an injunction restoring him to possession on the basis of a cross-claim in damages against the landlord for damage suffered as a result of timber on the demised land being cut down and carried away.304 But whatever the position formerly was, a tenant's liability to pay rent is now regarded as being no different in kind to other forms of indebtedness as regards set-off, so that an equitable set-off may proceed if the tenant's cross-demand is sufficiently closely connected with his or her liability to pay rent.305 The principle was confirmed in British Anzani (Felixstowe) Ltd v International Marine Management (UK) Ltd.306 The plaintiff had a leasehold interest in a plot of land. It agreed with the defendant that it would construct a warehouse on part of the land, after which it would grant an underlease (p. 204) to the defendant. Under the terms of the agreement, the plaintiff was obliged to make good any defects which appeared in the floor of the warehouse. The building was completed and a sub-lease entered into. The plaintiff subsequently sued the defendant for arrears of rent, whereupon the defendant raised as a defence a cross-demand against the plaintiff for breach of the agreement to repair defects in the floor. Forbes J held that there was a sufficiently close connection between the demands to give rise to an equitable set-off, notwithstanding that the cross-demand did not arise out of the lease itself, but rather pursuant to the original agreement.307

5.68  Equitable set-off against rent has been recognized in the case of a breach of a covenant to repair or other similar undertaking308 and a breach of a covenant for quiet enjoyment.309 It has been suggested that the set-off is available in the case of any cross-claim arising out of the provisions of the lease and the operation of the lease.310 Under modern formulations of the principle governing the availability of equitable set-off, a cross-claim arising out of the same contract as the claim would ordinarily give rise to an equitable set-off, but it is still the case that there is no universal principle that cross-claims arising out of the same contract (p. 205) may be set against one another in all circumstances.311 It should not therefore suffice that the cross-claim arises out of the provisions of the lease. The point is illustrated by the New South Wales decision in Phoenix Commercial Enterprises v City of Canada Bay Council.312 A local council had leased land to the plaintiff to be used for the purpose of erecting advertising structures. The leases contained a provision to the effect that, if the council approved the erection of a general advertising structure on other land within the council's local government area, it would be liable to pay an amount by way of compensation to the plaintiff fixed by reference to the rental. Subsequently, the council approved the erection of other advertising structures, thereby triggering the operation of the provision. The claim for rent and the cross-claim for compensation both arose out of the leases, but it was held that the circumstances did not give rise to an equitable set-off against the rent. The council's liability to pay compensation was not a consequence of a breach of the lease (there being no promise or undertaking by the council not to approve other advertising structures), and the physical enjoyment or use of the demised land for which the rent was payable was unaffected. Moreover, the lease provided for interest on both the amount payable by the council and on unpaid rent, but at different rates. This suggested that the claims were separate.313

5.69  In the Phoenix Commercial Enterprises case, the court emphasized the lack of any effect on the use and physical enjoyment of the demised premises. Earlier, Blackburne J considered a suggested limitation on the scope of the set-off in similar terms in Star Rider Ltd v Inntreprenneur Pub Co.314 Counsel had submitted that equitable set-off against a landlord's claim for outstanding rent is confined to a claim which relates to the quality of occupation of the demised premises. Blackburne J said that he was unwilling to attempt a definition of what must be established in order to give rise to an equitable set-off against unpaid rent, but that he would ordinarily expect the cross-claim to be of that nature. This is similar to the position that has been said to apply in the case of a time charter of a ship, that equitable set-off is confined to cases where the shipowner has wrongly deprived the charterer of the use of the ship or has prejudiced the charterer in the use of it.315 Subsequently, however, the Court of Appeal in Courage Ltd v Crehan316 rejected the proposition that equitable set-off against rent is limited to claims affecting the tenant's physical use or occupation of the premises, Morritt LJ (who gave the judgment of the court) commenting that, while the connection referred to is likely to be sufficient, it should not in all cases be necessary.317 For example, if (as in that case) the lease required the tenant to carry on a particular business with the landlord, he could see no reason why cross-claims arising out of the conduct of the business should not be set off against rent. In support of a broader view, Morritt LJ referred to the decision of the New Zealand Court of Appeal in Grant v NZMC Ltd.318 In that case (p. 206) an equitable set-off was allowed against rent in circumstances where tenants were induced to enter into the lease by a collateral contract with the lessor pursuant to which the lessor agreed to refer business to the tenants, and the lessor breached that agreement. The point is also illustrated by the later decision of the Court of Appeal in Fuller v Happy Shopper Markets Ltd,319 where a tenant liable for unpaid rent was allowed an equitable set-off in respect of a claim for earlier overpayments of rent under the lease.320 On the other hand, a set-off was denied in Courage Ltd v Crehan.321 The tenant of a public house was sued for arrears of rent. The lease contained a ‘beer tie’322 that was alleged to have infringed (the former) art. 85 of the EC Treaty. The Court of Appeal considered that the connection between the claim for rent and any claim in damages that may have resulted from the breach323 was tenuous and not such as to support a set-off. Of particular significance was the circumstance that art. 85 did not avoid one tie in isolation from other similar ties. The avoidance of one tie arose from the combined effect of that and other similar ties in foreclosing the market to outsiders, and the other ties which were necessary to avoid the tie in the present case had no connection with the tenant's obligation to pay rent. Further, the invalidity of the tie did not affect the validity of the lease or the covenant to pay rent. Therefore the right of the landlord to the rent was not impeached by the cross-claim.

5.70  The Star Rider case concerned a similar fact situation to that in issue in Courage Ltd v Crehan. In similarly denying a set-off, Blackburne J commented that, at most, the tie affected the extent to which the plaintiff was able to derive profit from the use of the premises. This suggests that a cross-claim based upon conduct which merely affected the profit that the tenant could derive from the premises does not suffice for an equitable set-off.324 However, a general proposition expressed in those terms would not represent the law. The situations referred to by the Court of Appeal in Courage Ltd v Crehan325 in which it was accepted that a set-off may arise, being the circumstances in issue in Grant v NZMC Ltd326 and the case (p. 207) of a lease which required the tenant to carry on a particular business with the landlord and a cross-claim had arisen out of the conduct of the business, illustrate the point. In addition, there is early authority which suggests that a set-off may be available if the landlord's conduct affected the tenant's ability to get rent from the land, which is a function of profit-ability. In Beasley v Darcy327 a landlord brought an action against the tenant for ejectment for non-payment of rent. The tenant applied for relief from forfeiture, based upon a cross-claim against the landlord for damages occasioned by cutting down and carrying away timber on the demised land. The House of Lords affirmed a decree by the Lord Chancellor of Ireland328 granting the tenant relief from forfeiture on condition that he paid what was due for rent after deducting the damages. This was a case in which there was physical damage to the land. Nevertheless, the point that has been emphasized in later discussions of the case is the effect of the conduct on the tenant's ability to pay rent from the land. In O'Mahony v Dickson329 Lord Redesdale said that the money that was due to the tenant in Beasley v Darcy ‘ought, in point of conscience, under the circumstances, to have been paid by the landlord, in order to enable the tenant to pay his rent; the nature of the demand for damages, supposing a loss by the tenant of the produce of the land, arising from the act of the landlord’.330 Similarly, Bramwell B in Stimson v Hall,331 justified the decision on the ground that the landlord ‘had committed a trespass on the land which rendered it of less value, and prevented the tenant, to a certain extent, from getting the rent out of it’.

5.71  Where rent is payable periodically, the question may arise whether a cross-claim against the landlord which arises in one period may be set off against rent due for another period. The question of set-off in relation to periodic payments was considered earlier.332

5.72  The discussion above relates to equitable set-off of unliquidated cross-demands. If the tenant's cross-demand is for a liquidated sum, a set-off against a claim for rent may proceed on the basis of mutual debts under the Statutes of Set-off333 as a defence to an action for payment.

(2)  Forfeiture for non-payment of rent

5.73  Equitable set-off and the right of set-off conferred by the Statutes of Set-off differ in a fundamental respect. Equitable set-off is a substantive defence which may be set up by a person as an immediate answer to liability.334 The Statutes, on the other hand, only provided a procedural defence, in the sense that prior to judgment for a set-off the rights and (p. 208) obligations consequent upon being a creditor or a debtor still attach.335 This distinction may be important in the context of forfeiture and re-entry for non-payment of rent. Because of the substantive nature of equitable set-off, a landlord is not permitted to proceed on the basis that the tenant has defaulted in payment of rent to the extent that the tenant has available that form of set-off. As a result, the landlord would not be justified in claiming forfeiture, and the tenant would have a defence to an action for possession.336 However, given that the defence under the Statutes is merely procedural, a landlord should be entitled to assert that a tenant relying on this defence nevertheless has defaulted in payment of rent, and therefore under the contract the landlord has a ground for forfeiting the lease. The question then should be whether the court in its discretion would grant relief from forfeiture.337

(3)  Distress

5.74  Traditionally, a right of set-off under the Statutes of Set-off has not been regarded as a ground sufficient to protect a tenant against a landlord levying distress for rent.338 The Statutes only provided a procedural defence to an action at law,339 whereas distress is a form of self-help remedy to which a landlord is entitled without recourse to legal process. On the other hand, equitable set-off is a substantive defence which may be set up independently of an order of the court,340 in the sense that the circumstances render it unconscionable for a creditor to proceed on the basis that the debtor has defaulted in payment to the extent of the set-off.341 Therefore, when a tenant is possessed of a cross-claim that gives rise to an equitable set-off, the landlord should not be permitted to assert that the tenant is in arrears in payment of rent so as to entitle the landlord to distrain for non-payment. Consistent with that view, the Court of Appeal in Eller v Grovecrest Investments Ltd342 granted an (p. 209) injunction to a tenant to restrain the landlord from proceeding against the tenant's goods because of an equitable set-off. However, the substantive nature of the defence was not referred to, and there are indications that the court would have been sympathetic to the view that the availability of a procedural defence of set-off under the Statutes should have the same effect. Thus, Hoffmann LJ343 said that: ‘It is contrary to principle that a landlord should be able to recover more by distress than he can by action’,344 which would appear to be equally applicable when a tenant has a defence under the Statutes to an action for payment of rent. Hoffmann LJ concluded his judgment by commenting that ‘this court is free to hold that set-off is available against a claim to levy distress’,345 without drawing a distinction between the various forms of set-off. However, in his later judgment in Aectra Refining and Marketing Inc v Exmar NV,346 Hoffmann LJ appeared to distinguish between equitable set-off and set-off under the Statutes in this context, so as, apparently, to re-assert the traditional position in relation to the Statutes. More recently, Lightman J affirmed that view in Fuller v Happy Shopper Markets Ltd.347

(4)  Payment in satisfaction of an obligation of the landlord

5.75  Whatever the position in relation to a landlord's right to levy distress where the tenant is entitled to a set-off under the Statutes, it is necessary to distinguish the cases which have held that, where a sub-tenant is compelled by the superior landlord to pay a sum owing by the sub-tenant's immediate landlord for unpaid rent or other like charges, to the extent of the payment the immediate landlord cannot levy distress for unpaid rent.348 The principle applies where the subtenant's payment was such as to give rise to a right of action against the immediate landlord for money paid to his use,349 but the sub-tenant's right nevertheless is not characterized as a set-off.350 When a sub-tenant is compelled to make a payment to the superior landlord which ought to have been made by the immediate landlord, the sub-tenant is considered as having been authorized by the immediate landlord to apply rent which is either due or accruing due to the immediate landlord in this manner.351 Accordingly, the basis upon which the sub-tenant impugns a subsequent attempt by the immediate landlord to distrain for unpaid rent is that the rent alleged to be outstanding in fact has been paid.352

(p. 210) 5.76  The principle is not confined to sub-tenancies. It applies generally to payments made to encumbrancers having a title paramount to that of the landlord.353 Thus, it has been held to apply when a tenant paid sums owing by his or her landlord to a mortgagee or to a rentchargee with power to distrain.354 Indeed, in a passage which Millett LJ later quoted with approval in Mortgage Corporation Ltd v Ubah,355 Forbes J, in the British Anzani case,356 expressed the principle broadly in terms of a payment by the tenant ‘in respect of some obligation of the landlord connected with the land demised’. To a like effect, Millett LJ, in the Mortgage Corporation case,357 spoke in terms of ‘expenditure which it was the landlord's legal obligation to defray’, referring by way of example to the payment of insurance. Further, while the principle has been expressed in terms of a payment made under compulsion,358 in that same passage Forbes J referred instead to a payment made at the ‘request’ of the landlord. This is consistent with the explanation of the principle when expressed in terms of compulsion, that a landlord is presumed to have authorized the tenant to apply rent in satisfaction of paramount claims on the land.359 In the early case of Taylor v Beal,360 to which Forbes J referred, the report states that part of the rent in issue was paid by the tenant to a rentchargee ‘by the commandment of the lessor’, and this was held to provide a defence to an action by the lessor for payment of rent.

(5)  Recoupment

5.77  A principle which is analogous to, but which nevertheless is distinct from, set-off may apply where leased premises have fallen into disrepair and responsibility for the repairs is on the landlord.361 In such a case, the tenant may expend money in executing the repairs and recoup him or herself from future payments of rent or from arrears of rent.362 This is not bound up with technical rules of set-off, but rather it is an ancient common law right of recoupment which entitles the tenant to treat the amount expended on repairs as payment (p. 211) of rent.363 As early as 1591, Gawdy J in Taylor v Beal364 is reported to have said365 that: ‘the law giveth this liberty to the lessee to expend the rent in reparations, for he shall be otherwise at great mischief, for the house may fall upon his head before it be repaired; and therefore the law alloweth him to repair it, and recoupe the rent.’366 There is surprisingly little case law on this right, but its existence appears to have been accepted in 1795 in Waters v Weigall.367 The tenant in that case had covenanted to keep the premises in repair ‘accidents by fire and tempest excepted’. The house was damaged by tempest and, being in want of emergency repairs, the tenant repaired it himself in order to prevent further mischief.368 The landlord refused to allow the tenant to deduct the cost of repairs from the rent, and brought an action for payment of rent. The tenant then filed a bill in the equity side of the Exchequer, seeking relief in the form of a right to retain the amount of the repairs out of the rent. It appears from the report of the argument in support of the bill that the tenant proceeded in equity because there was no express covenant in the lease that the landlord was liable to repair in the case that happened, and it was thought that consequently the tenant did not have a cross-claim at law against the landlord.369 For that reason, MacDonald CB held that the tenant similarly was not entitled to relief in equity. Nevertheless, it seems clear that in the opinion of the Chief Baron a right of recoupment would have been available if the landlord had been bound to repair in consequence of the accident that happened.370

5.78  The next reported occasion on which it appears that English courts were called upon to consider the right of recoupment was in 1971, in Lee-Parker v Izzet.371 Goff J in that case (p. 212) granted a declaration to tenants to the effect that, in so far as repairs carried out by the tenants were within the express or implied repairing covenants of the landlord, including those imported by s. 32(1) of the Housing Act 1961,372 they were entitled to deduct373 the proper cost from future payments of rent, and, moreover, to the extent of such proper costs they were not liable to be sued for the rent. Further, if a tenant with a right of recoupment has, to the extent of the sum expended, a defence to a claim for rent, the availability of the right should also provide an answer to a claim to distrain,374 on the ground that the rent has been paid.375 Subsequently, Megarry VC held in Asco Developments Ltd v Gordon376 that a right of recoupment is available not only against future rent but also against arrears of rent.

5.79  A landlord must have information as to the existence of a defect in the premises, such as would put a reasonable man upon inquiry as to whether works of repair were needed, before an obligation arises to carry out the works.377 The landlord's obligation is to effect the repairs within a reasonable time of receiving notice.378 Consistent with that proposition, it has been said that the landlord must have notice of want of repair before the right of recoupment can be exercised.379 This may give rise to difficulty in a situation in which the damage is such that emergency repairs are necessary in order to prevent the premises sustaining further damage. There is much to be said for the view that, in cases of emergency, the tenant should be able to effect repairs and recoup the expense from rent despite the absence of prior notice to the landlord.380

5.80  Forbes J in British Anzani (Felixstowe) Ltd v International Marine Management (UK) Ltd381 suggested a limitation on the right of recoupment, that it must not be based upon a sum which is regarded as unliquidated damages. By this he meant that it must be in respect of a sum certain which has actually been paid, and of which, in addition, the quantum has either been acknowledged by the landlord or in some other way it can no longer be disputed by him. But, notwithstanding that Forbes J's suggestion has since been referred to with approval,382 the better view is that there is no such limitation, and that, as long as the (p. 213) expenditure was properly incurred by the tenant,383 it makes no difference that the quantum is disputed by the landlord.384 Forbes J based the suggested limitation upon the judgment of Lord Kenyon CJ in Weigall v Waters.385 Weigall v Waters was decided at common law, and was in respect of the same situation considered in the earlier proceedings in equity referred to above in Waters v Weigall. The landlord was suing for rent, and the tenant sought to set off his expenditure incurred in effecting the repairs. Lord Kenyon held against a set-off, inter alia on the ground that, if the landlord indeed was liable to repair the premises, the defendant's cross-demand would have had to be assessed by a jury and consequently it was for unliquidated damages. However, it is important to note that the only defence pleaded by the defendant was set-off, and a prerequisite to a set-off in an action at law under the Statutes of Set-off was mutual debts.386 The defendant had not pleaded the alternative defence that he was entitled to recoup his expenditure from rent, and that this recoupment constituted payment of the rent.

F. Specific Performance

5.81  The question may arise whether a right of set-off constitutes a defence to an action for specific performance of a contract. In Phipps v Child,387 the plaintiff and the defendant agreed that the defendant would purchase the plaintiff's interest in a colliery. The defendant failed to complete the purchase in accordance with the contract, whereupon the plaintiff sought an order for specific performance. The defendant argued that, as a result of dealings between the parties, the plaintiff was liable to him for a sum of money which should be set off against the purchase money. Sir Richard Kindersley VC rejected the defence, commenting: ‘There may be a right in the Defendant to bring an action against the Plaintiff. But, if there is such a right, that is not a reason for non-performance of the contract.’388 However, the decision, and the Vice Chancellor's comment, should be considered in the context that the monetary cross-demands in issue appear not to have been such as would have given rise to a set-off in an action for the price.389

5.82  This question of the availability of set-off as a defence to an action for specific performance came before the Court of Appeal in BICC Plc v Burndy Corporation.390 The plaintiff and the defendant had traded together for a number of years in a joint enterprise. They decided to dissolve the relationship, and accordingly entered into a number of agreements. (p. 214) One agreement provided for the continued sale of goods by the defendant to the plaintiff. According to a second agreement, the plaintiff was responsible for the processing and maintenance of the joint rights, and the defendant had to reimburse the plaintiff for half of any expenses thereby incurred. This second agreement further provided that, if either of the parties failed to fulfil its obligations under the agreement, the party not in default could require the party in default to assign to it the defaulter's interest in the joint rights. The plaintiff incurred expenses in relation to a number of joint rights and duly invoiced the defendant for half of that sum. When the defendant failed to make reimbursement within the stipulated time, the plaintiff claimed that it was entitled to an assignment of the defendant's interests in the joint rights pursuant to the second agreement, and brought an action seeking specific performance of the agreement. As a defence, the defendant argued that it had a right to set off against the sums owing by it the sums due to it from the plaintiff under the first agreement for the sale of goods. The form of set-off considered to be in issue was the right to set off mutual debts under the Statutes of Set-off.391 It was not regarded as a case of equitable set-off. Dillon LJ, with whom Ackner LJ concurred, considered that statutory and equitable set-off both constitute a good defence to a claim for specific performance. That view would seem to be correct with respect to equitable set-off.392 Equitable set-off is a substantive defence which may be invoked independently of an order of the court.393 If a person has a money obligation under a contract but also has a cross-demand which is suf-ficiently closely connected to give rise to an equitable set-off, the other party to the contract could not in good conscience assert that moneys are due to it from the first person to the extent of the value of the cross-demand, in which case that other party should not be entitled to an order for specific performance when the right to the equitable relief sought depends upon a recognition of the existence of that very debt. However, this explanation would not extend to the Statutes of Set-off.394 Unlike equitable set-off, the defence provided by the Statutes is procedural, in that the set-off depends for its effect upon a judgment. Prior to judgment for a set-off each of the parties is still indebted to the other, and the rights consequent upon being a creditor still attach, as do the obligations and liabilities consequent upon being a debtor.395

5.83  The third member of the Court of Appeal, Kerr LJ, similarly refused to grant specific performance, though he adopted a different approach. In his Lordship's opinion the existence of a right of set-off, whether legal or equitable, does not per se provide a defence to a claim for specific performance, though it does constitute a factor relevant to the exercise of the court's discretion in determining whether to grant the relief sought. The problem with this view, in so far as it applies to substantive equitable set-off, is that, if indeed the cross-demands are such that an equitable set-off would be available, it is difficult to see how (p. 215) a court could ever grant an order for specific performance without detracting from the substantive nature of the defence. On the other hand, there is much to commend Kerr LJ's analysis in relation to the availability of a statutory right of set-off upon an application for an order for specific performance. The better view is that it constitutes a factor which, along with other relevant circumstances, the court should take into consideration in the exercise of its discretion. Other cases support this approach.396 In the case before him, Kerr LJ noted that the conduct of the plaintiff throughout the negotiations between the parties had been inconsistent with the applicability of the agreement for an assignment, which it suddenly sought to impose without any warning.397 This factor, when combined with the defend-ant's claim for a set-off under the Statutes, led Kerr LJ to conclude that an order for specific performance was inappropriate.

5.84  In BICC v Burndy, set-off was raised as a defence to an application for an order for specific performance. Alternatively, the applicant for the order could assert a set-off. This could arise where the applicant's obligation under the contract is to pay money. In order to obtain specific performance the applicant must show that he or she is ready and willing to perform his or her own obligations under the contract, but because of an equitable set-off the applicant may assert that he or she need only tender a reduced amount, after taking into account the set-off, in order to satisfy that requirement. This issue is considered below.398

5.85  Consider that a vendor has entered into a contract to sell land to a purchaser, who happens to be separately indebted to the vendor, but the vendor becomes bankrupt before conveyance. In Re Taylor, ex p Norvell,399 the Court of Appeal400 held that the purchaser in such a case is entitled to specific performance of the contract on terms that the purchase price should be reduced to the extent of a set-off available to the purchaser pursuant to the set-off section in the insolvency legislation.401 Buckley LJ in his judgment402 noted that title had been accepted before the bankruptcy, so that, when the bankruptcy occurred, there was nothing to be done but for the purchaser to pay the money and the vendor to execute the conveyance. However, the preferred view was expressed by Cozens-Hardy MR,403 that it was not material when title was accepted as long as a good title had in fact been made. A similar result should follow when the vendor is not bankrupt or in liquidation, so that the insolvency set-off section does not apply, but the purchaser has a cross-action which is available as an equitable set-off.404

(p. 216) G. Set-off as a Sword

(1)  Equitable set-off

5.86  It is sometimes said that set-off is a shield, not a sword,405 an aphorism that, in Australia, has been said to have the same meaning in this context as it has in the case of equitable estoppel. In other words, it is capable of being used offensively, but whether or not it can be used offensively it is also capable of being pleaded as a ground for absolution, as a shield.406 When a substantive defence of equitable set-off is in issue,407 the set-off should be capable in an appropriate case of being used offensively. For example, an applicant for a decree of specific performance must show that he or she is ready and willing to perform his or her own essential obligations under the contract. If this involves the payment of money, the applicant should be entitled to assert that the liability in question is reduced because of an equitable set-off available against the defendant.408 In that regard, in contracts for the sale of land where there is a deficiency in the quantity or quality of the estate agreed to be transferred, for example, because the vendor does not have title to part of the land,409 or because the vendor's title is different to that which he or she represented,410 or because the property deteriorated as a result of the vendor's neglect between the date of the contract and the date the purchaser obtained possession,411 the purchaser may obtain an abatement in the price by way of compensation for the deficiency. Further, there is authority for the proposition that a purchaser seeking specific performance need only prove a readiness and a willingness to tender the contract price less the amount of the abatement.412 This right to an abatement (p. 217) was developed independently of the principles of set-off. It does not apply where there is a breach of contract by the vendor which does not have the effect of lessening the value of the property as such.413 However, in the cases in which that proposition was accepted, the possible application of equitable set-off was not considered. If the circumstances are such as to give rise to an equitable set-off, the vendor's title to the claim for the price is impeached in equity to the extent of the set-off, such that the vendor to that extent is not permitted in equity to assert that any moneys are owing by the debtor.414 Given this substantive operation, it is suggested that a purchaser entitled to an equitable set-off should be in a similar position in an application for specific performance as a purchaser entitled to an abatement in the purchase money, in that the purchaser should only be required to show that he or she is ready and willing to pay the price as reduced by the set-off.415

(2)  Statutes of Set-off

5.87  It is more difficult to see how the availability of a right of set-off under the Statutes of Set-off could be used offensively. The nature of this defence is such that it has a procedural operation,416 in the sense that the Statutes only authorized a set-off if it is pleaded as a defence to an action for payment of a debt. Until such time as judgment for a set-off is obtained, each of the parties has the rights and obligations of creditor and debtor in relation to the cross-debts. Therefore, if in the example referred to the applicant seeking specific performance merely tendered the balance after deducting a separate debt owing to him or her by the defendant, the applicant would not have shown that he or she was ready and willing to perform the applicant's own obligation.

H. Foreign Currencies

5.88  It may be that one or both of the claims in a proposed set-off is in a foreign currency. The question of how a set-off should proceed is considered, first, in the context of the Statutes of Set-off, and then in relation to equitable set-off.

(1)  Statutes of Set-off

5.89  Until comparatively recently it was a settled principle of English law that, when a foreign currency obligation was enforced in an English court, any judgment for the plaintiff had to be in sterling measured at the rate of exchange prevailing at the date when the obligation became due and payable.417 However, in 1975 the House of Lords held in (p. 218) Miliangos v George Frank (Textiles) Ltd418 that this restriction no longer applies. An English court may give judgment for a sum of money expressed in a foreign currency and, if the defendant fails to tender payment in that currency, execution may issue for the sterling equivalent. Conversion for this purpose theoretically should take place at the rate prevailing at the date of actual payment.419 But, as Lord Fraser of Tullybelton pointed out,420 theory must yield to practical necessity to the extent that, if the judgment has to be enforced in England, it must be converted before enforcement.421 Accordingly, the date of conversion was said to be the date that the court authorizes enforcement of the judgment in sterling.422

5.90  The effect of this development upon set-off under the Statutes of Set-off has yet to be deter-mined. The Law Commission, in its report on Private International Law Foreign Money Liabilities,423 suggested that a right of set-off should not be available in an action when different currencies are involved. Each party should obtain judgment for the amount of his or her claim expressed in the appropriate currency, though, as a qualification, it suggested that neither judgment should be enforceable without the other judgment being taken into account. The problem with this proposal is that it may have the effect of making the parties to mutual debts vulnerable to an assignment or other intervening third party interest. If one of the claims is assigned, the debtor on that claim would not have a right of set-off available as a defence to an action brought by the assignor which could be asserted against the assignee.424 The recommendation that the judgments themselves should be capable of being set off at the date of enforcement would not assist in this situation, since an assignee only takes subject to prior equities, or defences. A right of set-off that only accrues upon the enforcement of a judgment could not be classed as a defence. Nor, on one view, would it be a prior equity. An alternative, and the preferable, approach is to convert the foreign currency into sterling at the rate prevailing at the date of judgment for a set-off. If both demands are in foreign currencies, the currency of the lesser debt should be converted into the currency of the greater debt at the date of judgment, and a set-off should then be effected.425 This is consistent with the Miliangos principle, since the set-off effectively constitutes payment and, to the extent of the set-off, conversion accordingly takes place at the time of payment. Once the balance is struck in this manner, if the currency of the balance is not sterling and payment is not forthcoming in that currency, it should be converted into sterling at the date that leave is given to enforce the judgment, in accordance with the Miliangos case.

(p. 219) (2)  Equitable set-off

5.91  Equitable set-off differs from set-off under the Statutes of Set-off in that it provides a substantive rather than a procedural defence.426 This does not mean that it operates as an automatic extinction of cross-demands prior to judgment for a set-off. Rather, the notion that the defence is substantive is a consequence of the closeness of the connection between the cross-claims, and its effect is to render it unconscionable for the creditor to assert that moneys are due to it from the debtor to the extent of the debtor's cross-claim while the circumstances exist which support the set-off. Therefore, where a contract permits a credior to take a particular course of action if the debtor defaults in payment, for example a shipowner's right to withdraw the vessel in the event of non-payment of hire, or a landlord's right to terminate the lease in the event that rent is not paid, the creditor would not be permitted to take that course of action if the debtor has an equitable set-off overtopping the claim.427

5.92  There is little authority on the question of foreign currency claims in the context of equitable set-off,428 but the following is consistent with the true nature of the defence. When an equitable set-off is pleaded as a defence to an action and one or both of the claims is in a foreign currency, the principle should be the same as that suggested above for the Statutes of Set-off, in that conversion should take place by reference to the exchange rate applicable at the date of judgment for a set-off. However, the creditor's conscience is affected even before judgment, so that to the extent of the defence the creditor is not permitted to proceed on the basis that the debtor has defaulted in payment. In the determination at any point in time prior to judgment whether the debtor has defaulted, and whether the creditor can take action on the basis that a default has occurred, regard should be had to the exchange rate at that time.429

5.93  What if foreign currency cross-claims are interest bearing? The analysis in that circumstance should be as follows. Conversion of the principal amounts (and accrued interest) should take place at the date of judgment for a set-off. Interest, on the other hand, ordinarily would accrue on the daily balance. When a creditor has an interest bearing debt the subject of an equitable set-off, the sum upon which interest accrues is reduced to the extent of the cross-claim while circumstances exist which support the set-off.430 Therefore, when foreign currency cross-claims are interest bearing, prima facie there should be a notional conversion and set-off of the principal amounts on each day during the relevant period, and interest should be calculated each day on the notional daily balance at the rate applicable to the currency of the greater of the claims on that day.

(p. 220) 5.94  However, a different procedure was adopted in New South Wales in a case concerned with a statutory power to include interest in the sum for which judgment was given, calculated from the time when the cause of action arose. In Gilsan v Optus (No. 3),431 the plaintiff had foreign currency claims against the defendant, and the defendant had a cross-claim in Australian dollars against the plaintiff. It was accepted that equitable set-off applied, and one of the questions in issue was the calculation of interest for the purpose the court's statutory power to award interest on judgments. The defendant had provided services to the plaintiff which facilitated the business conducted by the plaintiff, and by carrying on its business the plaintiff became entitled to receive payments from the defendant.432 The defendant supplied the services to the plaintiff month by month, and the defendant was obliged to pay the plaintiff, in respect of the business generated by the plaintiff by use of those services, month by month.433 McDougall J considered that a monthly set-off should occur, with the requisite currency conversion taking place as at the end of the month. Interest was to accrue on the monthly balance in favour of the party to whom the balance was owing at the rate applicable to the currency of the balance.434

I. Contracting Out of Set-off

(1)  Equitable set-off and common law abatement

General principle

5.95  It may be important for cash flow reasons that a party should receive payment in full under a contract so that, if the other party has a cross-claim which otherwise would give rise to an equitable set-off or a common law defence of abatement, that other party should not be entitled to rely upon it as a justification for tendering a reduced amount, but should be required to seek his or her remedy in separate proceedings. There is no ground of public policy which would preclude parties to a contract from agreeing to exclude defences of equitable set-off and abatement,435 including in relation to a cross-claim based on fraud.436

5.96  Different views have been expressed as to the approach to be adopted in the interpretation of a contract which, it is asserted, operates to exclude or restrict defences of set-off and (p. 221) abatement. On the one hand, Lord Diplock in Gilbert-Ash (Northern) Ltd v Modern Engineering (Bristol) Ltd437 said that there is a presumption that the defences are not excluded, and that clear words are required to rebut the presumption:

It is, of course, open to parties to a contract for sale of goods or for work and labour or for both to exclude by express agreement a remedy for its breach which would otherwise arise by operation of law or such remedy may be excluded by usage binding upon the parties … But in construing such a contract one starts with the presumption that neither party intends to abandon any remedies for its breach arising by operation of law, and clear express words must be used in order to rebut this presumption.438

Lord Morris, on the other hand, considered that the question depends simply and solely upon the interpretation of the contract,439 an approach that was reflected in the judgment of Lord Cross of Chelsea (with whom Lord Hodson and Lord Wilberforce agreed) a year later, in Mottram Consultants Ltd v Bernard Sunley & Sons Ltd,440 Lord Cross said that: ‘one should approach each case without any “parti pris” in favour or against the existence of a right of set-off …’ While there is support for that view,441 the tendency in subsequent cases has been to refer to Lord Diplock's judgment as setting out the relevant principle. In other words, it is said that there is a presumption that the parties to a contract do not intend to give up rights of set-off and abatement otherwise available at law in the event of a breach by the other,442 and if they intend to exclude those rights they must use clear words.443 (p. 222) Clauses which refer expressly to set-off have been held to be effective to exclude the defence,444 but it is not necessary that the word ‘set-off’ be specifically used if it is otherwise clear from the language that the defence is intended to be excluded.445

5.97  There was no such clear implication in BOC Group plc v Centeon LLC,446 and the Court of Appeal therefore held that the contract did not exclude set-offs. Evans LJ, with whose judgment Brooke LJ agreed, framed the relevant question in terms of whether the clause in (p. 223) that case provided ‘with sufficient clarity’ that the purchaser was to pay the price regardless of any cross-claim that it may have had, and he emphasized that the court should take account of all the surrounding circumstances.447 He regarded this as consistent with the approach advocated by Lord Hoffmann in relation to the interpretation of contractual documents in Investors Compensation Scheme Ltd v West Bromwich Building Society.448 BOC v Centeon concerned the sale of a research and development company, Delta Biotechnology Ltd. The sale agreement provided for the payment of the price by way of instalments, and the present action was for payment of one of the instalments. The purchaser asserted a set-off in respect of cross-claims for damages for breach of the agreement and misrepresentation, but the vendor responded that set-off was precluded by the terms of clause 2.7 of the agreement. The clause provided that the purchaser's payment obligation was:

absolute and unconditional and shall not be affected by any transfer of any of the equity interest in Delta, the transfer of any or all of Delta's assets or business, the dissolution of Delta, the termination of the business of Delta (or any part thereof), the success or failure of any research projects undertaken by Delta, the future commercialization or otherwise of any products, Delta's future business prospects or technological or technical successes or by any other matter whatsoever.449

The vendor sought to justify its argument that set-off was excluded by reference to the inclusion of ‘whatsoever’, which, it said, is a word of the widest possible import.450 The difficulty with the argument was that the other matters listed were all concerned with the subsequent fate of Delta and its project, and the general words that followed the list were capable of referring to other factors concerned with the future progress of the venture. The word ‘whatsoever’, therefore, was ambivalent. Moreover, the parties were legally represented during the negotiation of the contract, and so they were aware of their legal rights. In that context the question was, what words might they have used to make their meaning clear if they had intended to exclude set-off? Evans LJ regarded the absence of words such as ‘deduction’, ‘withholding’ or ‘payment in full’ as an ‘eloquent silence’451 in that regard. In the circumstances, he considered that the clause did not provide with sufficient clarity that the right to invoke the defence was excluded.

5.98  Evans LJ in BOC v Centeon discussed the issue without recourse to the label ‘presumption’, and indeed he exhibited a degree of hesitancy in adopting that term.452 However, the rele vant passage in Lord Diplock's judgment in Gilbert-Ash has since been cited with evident approval in the House of Lords,453 and ‘presumption’ would seem to be accepted as an accurate description of the approach to be adopted in these cases.

(p. 224) 5.99  One should distinguish a provision to the effect that one party must pay ‘all sums immediately when due, without deduction or set-off’. The better view is that a contract in those terms would be ineffective to preclude an equitable set-off in relation to a damages cross-claim which is inseparably connected with a debt the subject of the plaintiff's claim, because the substantive nature of the set-off454 would mean that the plaintiff could not assert that the debt is ‘due’ for the purpose of the clause.455 That reasoning would not apply, however, in relation to set-off under the Statutes of Set-off. The statutory form of set-off has a procedural operation in that, prior to judgment for a set-off, the rights consequent upon being a creditor still attach, as do the obligations and liabilities consequent upon being a debtor.456 The availability of the set-off would not mean that the debt to the plaintiff is not due, in which case the clause should be effective to preclude reliance on that form of set-off.

5.100  If a contract provides that a debt is payable without set-off, contractual interest on the debt ordinarily should also be payable without set-off.457

Payment ‘without deduction’

5.101  Contracts often provide that payment is to be made ‘without deduction’, which invites the question whether those words are apt to exclude a defence of equitable set-off. The issue came before the Court of Appeal in Connaught Restaurants Ltd v Indoor Leisure Ltd.458 In dispute was a lease which provided that rent was to be paid ‘without any deduction’. The word ‘deduction’ is sometimes used by the courts to describe the result which follows when a right of set-off is exercised,459 and indeed Lord Salmon, in the Gilbert-Ash case,460 rejected the view that it does not describe the process of set-off in the case of a contract for the sale of goods where the purchaser sets up a cross-claim for damages under the contract in extinction of the purchase price. In the Connaught Restaurants case, however, Waite LJ considered that the term was ambiguous. He said that ‘deduction’ may be used in its strict sense to describe the ordinary process of subtraction, in other words the action of taking (p. 225) something away. The process of subtraction may encompass contractual or statutory deductions, where the contract or the statute authorizes a subtraction from rent.461 Alternatively, ‘deduction’ may be used in a broader sense, to describe the result which follows when one claim is set against another and a balance is struck. Because clear words are needed to exclude the remedy of equitable set-off, he considered that the word ‘deduction’ in the lease before him was insufficiently clear to achieve that result. In a short judgment Neill LJ agreed with Waite LJ's reasons, and Simon Brown LJ agreed with both judgments. The decision subsequently was followed by a differently constituted Court of Appeal in Edlington Properties Ltd v J. H. Fenner & Co Ltd.462

5.102  The Court of Appeal in the Connaught Restaurants case followed an earlier decision of the New Zealand Court of Appeal463 in which it was held that ‘deduction’ does not in its natural sense embrace a set-off. This view has been adopted in Australia,464 although there is also support there for the contrary view,465 and in Singapore.466 It is also consistent with the view expressed in relation to a stipulation in a time charter of a ship that hire was to be paid ‘without discount’,467 and similarly a stipulation that payment is to be made ‘without abatement’ has been said to be insufficiently precise to exclude set-off.468

5.103  While Waite LJ considered that the expression ‘without any deduction’ in the case before him was insufficient to exclude equitable set-off, he nevertheless contemplated that there (p. 226) may be instances where the context suggests by implication that the words were intended to have that effect.469 An illustration is Marubeni Corp v Sea Containers Ltd.470 It concerned a sale of containers by Marubeni to Sea Containers. The contract provided for payment of the price by instalments on the nominated due dates ‘without any deductions or withholdings whatsoever’. There were defects in some of the containers, and Sea Containers sought to ‘deduct’ by way of equitable set-off from an instalment of the price an amount corresponding to the damages flowing from the defects. Waller J accepted that neither ‘deduction’ nor ‘withholding’ is a term of art, and they could not be described as clear words. The question was one of construction in the context of the contract as a whole, and looking at the contract as a whole he held that the purported ‘deduction’ in respect of an equitable set-off was precluded by the exclusion of deductions and withholdings. In the first place, he said that the court has to find some meaning for the words and, in contrast to the Connaught Restaurants case, it was difficult in this case to see to what else they could apply. Moreover, the price was to be paid over a substantial period of nine years after delivery. Marubeni, therefore, in substance was providing finance, and it was likely that a finance party would insist that instalments should be paid without deducting for a cross-claim arising from a breach of warranty. In that respect he considered that the context was different from a building contract or a lease or a charter of a ship. Furthermore, the contract provided for a bank guarantee to secure payment of some of the instalments. If a claim were made against the bank on the guarantee, Sea Containers could not have exercised a right of set-off, and it would produce consistency in the contract if the same position were held to apply in relation to other instalments not secured by a bank guarantee.

5.104  In BOC v Centeon,471 Evans LJ referred to ‘payment in full without deduction or with-holding of any sort’ as being familiar words in the context of agreements which purport to exclude rights of set-off. If ‘deduction’ or ‘withholding’ is insufficiently precise to exclude set-off, the addition of ‘of any sort’ would hardly add the necessary clarity.472 It may also be queried whether ‘payment in full’ would overcome the perceived difficulty. It begs the question as to what constitutes ‘payment in full’, in circumstances where there is an equitable defence of set-off which renders it unconscionable for the creditor to assert that moneys are due from the debtor to the extent of the set-off.473 Evans LJ emphasized, how-ever, that there is not necessarily a magic formula, and where the parties do not expressly refer to set-off one should have regard to the surrounding circumstances of the case.474

(p. 227) 5.105  A stipulation in a lease that rent is to be paid without deduction ordinarily should not extend to the right of recoupment considered by Goff J in Lee-Parker v Izzet.475 This right of recoupment may apply where leased premises have fallen into disrepair, and the tenant expends money in executing the repairs in circumstances where responsibility for the repairs is on the landlord. The tenant in such a case may recoup the cost from future payments of rent or from arrears of rent. Goff J admittedly referred in his order to the right of the tenant to ‘deduct’ the cost of repairs from future payments of rent,476 though that expression may have been used for the sake of brevity.477 The exercise of the right does not involve a deduction from rent otherwise due, but rather the tenant is entitled to treat the amount expended on repairs as a payment of rent.478 Accordingly, a stipulation for payment ‘without deduction’ should not be relevant.479

5.106  On the other hand, in Totsa Total Oil Trading SA v Bharat Petroleum Corp Ltd480 Clarke J considered that the common law defence of abatement to an action for the price of goods sold and delivered or of work performed481 involves a ‘deduction’ from the price.482 The Totsa Oil case concerned a contract for the sale of oil on FOB terms. The contract provided that payment was to be made against the seller's invoice ‘without discount, deduction, set-off or counterclaim’. This was held to preclude a deduction from the price for short delivery.483

The effect of specifying some deductions

5.107  Because of the need for clear words to exclude equitable set-off, the fact that a contract makes provision for certain specified deductions from contract payments is not regarded as sufficient to give rise to an implication that a right of set-off in respect of other sums is excluded,484 though there is authority in Australia which suggests (p. 228) the contrary.485 The contract may go further, however, and stipulate that payments are to be made ‘less only’ a list of specified deductions.

5.108  In Mottram Consultants Ltd v Bernard Sunley & Sons Ltd,486 a building contract provided that the employer was to pay the amount specified in an architect's certificate ‘less only’ retention money and any sum previously paid. The printed form which the parties used originally provided for a third item, being any amount which the employer was entitled to deduct from or set off against any money due to the contractor by virtue of any breach of the contract by the contractor. However, the third item had been deleted. Lord Cross (with whom Lord Hodson and Lord Wilberforce agreed) said that: ‘When the parties use a printed form and delete parts of it one can, in my opinion, pay regard to what has been deleted as part of the surrounding circumstances in the light of which one must construe what they have chosen to leave in.’487 He said that the fact that the parties had deleted the third item showed that they had turned their minds to the question of deductions under the common law principle of abatement, and had decided that no such deductions should be allowed.488 That reasoning would apply equally to equitable set-off.489

5.109  Mottram v Sunley was complicated by the deletion. That factor was not present in relation to the clause in a standard RIBA building contract490 considered earlier in Gilbert-Ash.491 The clause appeared in the main contract, between the employer and the contractor, though it dealt with the contractor's obligation to pay the sub-contractor. It provided that the contractor had to pay the sub-contractor the amount stated in a certificate less only a list of a specified deductions. Lord Diplock said that this did not seem to him to be strong enough to amount to an undertaking by the contractor to the employer that the contractor (p. 229) would not rely on a common law defence of abatement in an action by a sub-contractor for payment. He considered that it was directed simply at calculating the amount of the instalment due to the sub-contractor, and not to defences available to the contractor if sued by the sub-contractor for payment.492 While those comments were expressed in the context of a defence of abatement, the view that Lord Diplock also expressed in his judgment, that clear words are required in order to rebut the presumption that neither party to a contract intends to abandon any remedies for its breach arising by operation of law, suggests that he would have regarded the provision similarly as being ineffective to preclude a defence of equitable set-off.493 As Mr Duncan Wallace commented in a note on Mottram v Sunley:

the right of set-off is so fundamental, and the potential injustices and anomalies of departing from it so great, that the mere use of the words ‘less only’ when referring to certain inevitable deductions required by the scheme of the contract (prior payment, retention money, and so on) should not be construed as intending to apply to and exclude other contingent situations which might justify a deduction under the general principles of law relating to defence, set-off, or counterclaim.494

With respect, there is much to commend that view.

Stay of execution

5.110  If there is an effective agreement excluding equitable set-off, this would not only preclude the defendant from being able to defend a claim for payment on the basis of a cross-claim, but in addition in a summary judgment application the court ordinarily would regard it as inappropriate to order a stay of execution pending adjudication on the cross-claim.495 As the Court of Appeal noted in Continental Illinois National Bank & Trust Co of Chicago v Papanicolaou496 when it allowed an appeal against an order granting a stay in this situation, the contrary conclusion would negate the very purpose of inserting a provision excluding rights of set-off, the purpose being to prevent a situation arising in which the creditor is (p. 230) kept waiting for payment. Admittedly, the contract in that case specifically stated that the debt should be paid without counterclaim as well as set-off, but Parker LJ's analysis suggests that the same result would have followed if the contract had only excluded set-off. The court nevertheless has a discretion to grant a stay, and his Lordship postulated that a stay may be granted in exceptional circumstances notwithstanding the exclusion.497 In that regard he said that it would not be enough that the defendant has a counterclaim which is likely to succeed, though he contemplated that it might suffice if there is such a counterclaim coupled with cogent evidence that the plaintiff would, if paid, be unable to meet a judgment on the counterclaim.498 But in the absence of special circumstances, execution on a judgment should not be stayed pending determination of a cross-claim if the contract has excluded defences of set-off.

Negligence claims

5.111  The Court of Appeal in the Continental Illinois case also noted that a clause which purports to exclude rights of set-off is not subject to the same rule of construction applicable to exclusion of liability clauses in relation to claims for negligence.499 In order to be effective to exclude liability for negligence it is usually necessary that the clause should refer specific-ally to negligence, or (possibly) use a sufficiently wide term such as ‘whatsoever’.500 However, it is not necessary that similar terminology be employed in order to exclude an equitable set-off based upon a cross-claim for negligence. The clauses serve different functions. An exclusion clause purports to exclude liability altogether, whereas a clause excluding set-off does not touch liability. The debtor can still prosecute the cross-claim to judgment, but in a separate action.

Arbitration clauses

5.112  While conceding that comments by Lord Salmon in the Gilbert-Ash case501 were against his view, Wood has suggested that a party to a contract might perhaps be taken to have agreed to exclude equitable set-off in relation to a disputed cross-claim if he or she has agreed to submit disputes to arbitration, and no arbitration has been held.502 Whether this is the case would depend upon the terms of the particular arbitration clause, but the usual clause providing for disputes to be referred to arbitration ordinarily should not require the debtor to pay in full if a cross-demand available as an equitable set-off has not been arbitrated. (p. 231) Indeed, the availability of an equitable set-off would mean that the debt is also in dispute, so that both the debt and the cross-claim should be referred.503 This is a consequence of the substantive nature of the defence.504

Conclusive evidence certificate

5.113  A contract may provide that a certificate from an authorized officer of one of the parties as to the amount owing to that party by the other shall be conclusive evidence of the amount owing. Conclusive evidence clauses are not contrary to public policy, and the courts will give effect to them in the absence of some factor such as fraud.505 On the other hand, subject to the specific terms of the agreement, a conclusive evidence certificate ordinarily should not have the effect of precluding recourse to an equitable set-off,506 which admits the existence of the debt at law, in the sense that an equitable set-off does not operate as an automatic extinction of cross-demands, but renders it unconscionable in equity for the creditor to treat the debtor as being indebted.507

5.114  The Unfair Contract Terms Act 1977 prohibits in certain situations contract terms which exclu
