This book presents an account of attribution in unjust enrichment. Attribution refers to how and when two parties – a claimant and a defendant – are relevantly connected to each other for unjust enrichment purposes. It is reflected in the familiar expression that a defendant be 'enriched at the claimant's expense'. This book presents a structured account of attribution, consisting of two requirements: first, the identification of an enrichment to the defendant and a loss to the claimant; and, secondly, the identification of a connection between that enrichment and that loss. These two requirements must be kept separate from other considerations often subsumed within the expression 'enrichment at the claimant's expense' which in truth have nothing to do with attribution, and which instead qualify unjust enrichment liability for reasons that should be analysed in their own terms. The structure of attribution so presented fits a normative account of unjust enrichment based upon each party's exchange capacities. A defendant is enriched when he receives something that he has not paid for under prevailing market conditions, while a claimant suffers a loss when he loses the opportunity to charge for something under the same conditions. A counterfactual test – asking whether enrichment and loss arise 'but for' each other – provides the best generalisation for testing whether enrichment and loss are connected, thereby satisfying the requirements of attribution in unjust enrichment.

Présentation de l'éditeur : "Goff & Jones is the leading work on the law of unjust enrichment. The first edition appeared fifty years ago, in 1966, and successive editions have played a major role in establishing the central importance of the subject for private and commercial law. The text is comprehensive in coverage and written by highly respected scholars who analyse and explain the principles governing claims in unjust enrichment, demonstrating how these principles have been applied through detailed discussion of case-law. The book is frequently cited in court and continues to set the agenda for future developments in the field. The new 9th Edition is completely up-to-date and contains detailed discussion of important decisions since the last edition. Many chapters have been rewritten to take account of significant new cases, and their impact on topics including the valuation of enrichments, the recovery of benefits from remote recipients, the recovery of benefits transferred by mistake, the recovery of money paid as tax that is not due, and the content of the tracing rules and their significance for the award of proprietary remedies."

"This book discusses developments in scholarship dedicated to reinvigorating the study of the broad domain of private law. This field, which embraces the traditional common law subjects-property, contracts, and torts-as well as adjacent, more statutory areas, such as intellectual property and commercial law, also includes important subjects that have been neglected in the United States but are beginning to make a comeback. The book particularly focuses on the New Private Law, an approach that aims to bring a new outlook to the study of private law by moving beyond reductively instrumentalist policy evaluation and narrow, rule-by-rule, doctrine-by-doctrine analysis, so as to consider and capture how private law's various features fit and work together, as well as the normative underpinnings of these larger structures. This movement is resuscitating the notion of private law itself in United States and has brought an interdisciplinary perspective to the more traditional, doctrinal approach prevalent in Commonwealth countries. The book embraces a broad range of perspectives to private law-including philosophical, economic, historical, and psychological- yet it offers a unifying theme of seriousness about the structure and content of private law."--

This highly-praised textbook provides detailed and incisive coverage of all aspects of restitution. The author's expert analysis and clarity of style will be invaluable to both students and practitioners with an interest in this area of law.

This book is the second in a series of essay collections on defences in private law. It addresses defences to liability arising in unjust enrichment. The essays are written from a range of perspectives and methodologies. Some are doctrinal, others are theoretical, and several offer comparative insights. The most important defence in this area of the law, change of position, is addressed in detail, but many other defences are treated too, as well as the interrelations between these defences within the law of unjust enrichment. The essays offer novel claims and ways of looking at problems in this challenging area of legal study.

This Restatement presents a distillation of the current state of the common law of unjust enrichment into a coherent set of doctrines. Written by an authority in the area, assisted by senior judges, academics, and practitioners, the Restatement offers a persuasive statement of the law in this newly recognized and uncertain branch of the common law.

This comprehensive yet accessible Research Handbook offers an expert guide to the key concepts, principles and debates in the modern law of unjust enrichment and restitution.
