This third edition of the only work to focus on damages under the United Convention on Contracts for the International Sale of Goods (CISG) maintains its purpose as the primary reference source for this topic. Addressing global judicial and arbitral decisions, the book demonstrates the differences between uniform international instruments and domestic laws, and comparatively analyses the calculation of damages under civil and common law systems under the CISG. A new chapter on penalty clauses examines the impact of recent cases in England (Cavendish Square Holding BV v Makdesi) and Australia (Paccioco v Australia and New Zealand Banking Group Ltd) concerning the interpretation of penalty clauses and their relationship with the CISG. Further new material includes: an expanded discussion of the question of good faith; new approaches relating to attorneys' fees; consideration of states that have recently ratified the CISG; and an examination of the developments in the EU in relation to the attempt to introduce a new harmonised contract law.
