This is the third book in the 'Ius Commune Casebooks for the Common Law of Europe' series,developed for use throughout Europe and aimed at those who teach, learn or practice law with a comparative or European perspective. The book contains excerpts from legal commentaries, leading cases and legislation from the main legal traditions within Europe (English, French and German law), as well as the Netherlands, but also relying on the contribution of mixed legal systems such as those of Scotland and South Africa. Unjustified Enrichment concerns the law of restitution and contains a wide selection of extracts from the basic texts and commentaries. The materials are chosen and ordered so as to foster comparative study, prefaced by comparative introductions and complemented with annotations prepared by a multinational team. The whole Casebook is in English.

Increasingly, in both common law and civil law jurisdictions, lawyers are seeking to formulate a law of restitution that can provide a reliable remedy in unjust enrichment actions. This pursuit has generated renewed interest in how the law of obligations should be divided. The movement can be seen as both a product of the recent calls for, and recognition of, an English law of restitution and a consequence, in civil law jurisdictions (where traditionally taxonomy has been taken far more seriously), of the modern quest for a general remedy which will overcome the widely-felt disadvantages of existing alternatives. This collection of essays is concerned with these modern developments. It identifies what constitutes unjust enrichment at the plaintiff's expense, and its available remedies, in a number of jurisdictions. Authors explore the boundaries between the law of restitution, the law of torts, and the law of contract. Their analyses reveal how the principle of restitution has permeated, hesitatingly at first and then with greater force, on a case-by-case basis, not only private law but also administrative law, criminal law, and other branches of the law. In the final analysis, unjust enrichment proves to be anything but a Trojan horse smuggled into the well-built structure of the law of obligations; it is a fully-fledged cause of action deserving an appropriate and satisfactory remedy. Scholars and jurists from thirteen countries met in Amsterdam on 18-20 October 2000, for a conference commemorating the late Professor Marcel Henri Bregstein (1900-1957). This book, which presents revised versions of the papers read during this conference, greatly clarifies the status and primary trendsin this important area of legal theory and practice, and is sure to be of value to legal scholars and practitioners everywhere.
