The fourth edition of this established work is a systematic study of the law of sale of goods with reference to UK and Commonwealth authorities and relevant UK and EU legislation. The book combines depth of treatment of problem areas with insightful commentary on possible lines of argument on traditionally difficult topics. It provides full coverage of content, interpretation, and performance issues relating to sale of goods agreements. The book also addresses the relevant aspects of consumer law, as well as issues such as recoverability of damages, currency, and interest. The work has been updated in its fourth edition to cover all recent developments in case law, most notably The Supreme Court in PST Energy 7 Shipping LLC v OW Bunker Malta Ltd (The Res Cogitans) [2016] UKSC 23, which has given rise to a new category of contract: the sui generis supply contract, for which no statutory model yet exists. Also examined in depth is the Consumer Rights Act 2015, which has profoundly affected the structure of sales law and, in a number of key instances, has also affected the substance of the law. This work remains the leading work of scholarship and an invaluable reference for all practitioners and scholars working in the field.
