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.

"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.

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."

Unjustified enrichment has been one of the most intellectually vital areas of private law. There is, however, still no unanimity among civil-law and common-law legal systems about how to structure this important branch of the law of obligations. Several key issues are considered comparatively in this 2002 book, including grounds for recovery of enrichment, defences, third-party enrichment, as well as proprietary and taxonomic questions. Two contributors deal with each topic, one a representative of a common-law system, the other a representative of a civil-law or mixed system. This approach illuminates not just similarities or differences between systems, but also what different systems can learn from one another. In an area of law whose territory is still partially uncharted and whose borders are contested, such comparative perspectives will be valuable for both academic analysis of the law and its development by the courts.

General Principles and the Coherence of International Lawprovides a collection of intellectually stimulating contributions from leading international lawyers to the discourse on the role of general principles in international law. Offering a comprehensive analysis of the doctrines, practices, and debates on general principles of law, the volume assesses their role in safeguarding the coherence of the international legal system. This important book addresses the relationship between principles of law and the other sources of international law, explores the interplay between principles of law and domestic and regional legal systems and the role of principles of law with regard to three specific regimes of international law: investment law, human rights law and environmental law.

This book is the first in a series of essay collections on defences in private law. It addresses defences to liability arising in tort. The essays range from those adopting a primarily doctrinal approach to others that examine the law from a more theoretical or historical perspective. Some essays focus on individual defences, while some are concerned with the links between defences, or with how defences relate to the structure of tort law as a whole. A number of the essays also draw upon concepts and literature that have been developed mainly in relation to the criminal law, and consider their application to tort law. The essays make several original contributions to this complex, important but neglected field of academic enquiry.
