Enrichment is key to understanding the law of unjust enrichment and restitution. This book provides a comprehensive analysis of the concept of enrichment and its implications for restitutionary awards. Dr Lodder argues that enrichment may be characterised either factually or legally, and explores the consequences of that distinction. In factual enrichment cases, the measure of enrichment is the objective value received. This is the basis of many awards of money had and received, quantum meruit, quantum valebat and money paid. In legal enrichment cases, the benefit is the acquisition of a specific right or the release of a specific obligation. The remedy is restitution of that right or reinstatement of that obligation. It is demonstrated that specific restitution of the defendant's legal enrichment is often the basis for resulting trusts, rescission, rectification and subrogation. This book has profound implications for understanding restitutionary awards and the relationship between the enrichment inquiry and other aspects of the law of unjust enrichment, including the 'at the expense of' inquiry and the defence of change of position.

"Although it is often referred to as "the third branch of private law", alongside contract and tort, the law of unjust enrichment and restitution is not well understood. That is true for a variety of reasons. The subject is seldom taught in law school. Many of the traditional cases speak in a language that is incomprehensible to modern ears. Most significantly, until now, there has not been a text that is structured in accordance with the modern Canadian principle of unjust enrichment.

Restitution is the body of law concerned with taking away gains that someone has wrongfully obtained. The operator of a Ponzi scheme takes money from his victims by fraud and then invests it in stocks that rise in value. Or a company pays a shareholder excessive dividends or pays them to the wrong person. Or a man poisons his grandfather and then collects under the grandfather’s will. In each of these cases, one party is unjustly enriched at the expense of another. And in all of them the law of restitution provides a way to undo the enrichment and transfer the defendant’s gains to a party with better rights to them. Tort law focuses on the harm, or costs, that one party wrongfully imposes on another. Restitution is the mirror image; it corrects gains that one party wrongfully receives at another’s expense. It is an important topic for every lawyer and for anyone else interested in how the legal system responds to injustice. In Restitution, Ward Farnsworth presents a guide to this body of law that is compact, lively, and insightful—the first treatment of its kind that the American law of restitution has received. The book explains restitution doctrines, remedies, and defenses with unprecedented clarity and illustrates them with vivid examples. Farnsworth demonstrates that the law of restitution is guided by a manageable and coherent set of principles that have remarkable versatility and power. Restitution makes a complex and important area of law accessible, understandable, and interesting to any reader.

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.

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 new edition of Unjust Enrichment by the editor of the Clarendon Law Series, is a fully updated, clear and concise account of the law of unjust enrichment. It attempts to move away from the use of obscure terminology inherited from the past. This text is the first book to insist on the switch from restitution to unjust enrichment, from response to event. It organises modern law around five simple questions: Was the defendant enriched? If so, was it at the claimant's expense? If so, was it unjust? The fourth question is then what kind of right the claimant has, and the fifth is whether the defendant has any defences. This second edition was revised and updated by Peter Birks before his death from cancer on 6 July 2004 at the age of 62. It represents the final thinking of the world's leading authority on the subject.

The publication of the Restatement Third: Unjust Enrichment and Restitution by the American Law Institute in July 2010 was an event of major importance, not only for the development of the law of unjust enrichment in the US, but also for global scholarship relating to this area of private law. The Restatement First appeared in 1937, and the Restatement Second was abandoned; hence the Restatement Third is the most significant survey of the American law on this topic for over 70 years. Private law has been a comparatively neglected area of study in US law schools for several decades, and this is particularly true of the law of unjust enrichment. However, the appearance of the Restatement Third has prompted a renewal of interest in the subject among US scholars, and it is hoped that the present volume of essays will contribute to this revival, while reflecting on the lessons to be learned from the Restatement by other legal systems. Featuring the work of leading scholars from the UK, Germany, South Africa, Canada, Hong Kong and Australia, the essays undertake critical and comparative analysis of the Restatement, and offer fresh insights into the rules that it articulates.
