This book is a collection of articles based on Understanding Unjust Enrichment,a symposium held at the University of Western Ontario in January 2003. The articles, written from the perspective of English, Australian, Canadian, German and Jewish law, deal with numerous theoretical and practical issues that surround restitution and unjust enrichment. The articles outline recent developments across the Commonwealth, explain the unjust enrichment principle and its component parts, and address discrete issues such as tracing, choice of law, disgorgement damages for breach of contract, and the use of unjust enrichment in the cohabitation context. The contributors are Kit Barker, Peter Benson, Jeffrey Berryman, Michael Bryan, Andrew Burrows, Robert Chambers, Gerald Fridman, Peter Jaffey, Dennis Klimchuk, Thomas Krebs, John McCamus, Mitchell McInnes, Stephen Pitel, Stephen Waddams and Ernest Weinrib.
