"Classification of Rights and Wrongs" from Christopher Columbus Langdell. American jurist (1826-1906).

It is now well established that the law of unjust enrichment forms an important and distinctive part of the English law of obligations. Restitutionary awards for unjust enrichment and for wrongdoing are clearly recognised for what they are. But these are recent developments. Before the last decade of the twentieth century the very existence of a separate law of unjust enrichment was controversial, its scope and content matters of dispute. In this collection of essays, a group of leading scholars look back and reappraise some of the landmark cases in the law of restitution. They range from the early seventeenth century to the mid-twentieth century, and shed new light on some classic decisions. Some argue that the importance of their case has been overstated; others, that it has been overlooked, or misconceived. All persuasively invite the reader to think again about some well-known authorities. The book is an essential resource for anyone, scholar, student or practitioner, with an interest in this fascinating area of the law.

This reprint delves into restitution of benefits obtained by mistake. The work is divided into three parts. The first chapter explores the different kinds of mistakes & seeks to classify them & the remedies available to settle them. Chapter two concentrates on mistakes in assumptions & how to avoid them. Chapter three discusses the difference between unilateral & mutual mistakes. William S. Hein & Co., Inc., 1993

Derived from the renowned multi-volume International Encyclopaedia of Laws, this practical analysis of the law of contracts in Japan covers every aspect of the subject - definition and classification of contracts, contractual liability, relation to the law of property, good faith, burden of proof, defects, penalty clauses, arbitration clauses, remedies in case of non-performance, damages, power of attorney, and much more. Lawyers who handle transnational contracts will appreciate the explanation of fundamental differences in terminology, application, and procedure from one legal system to another, as well as the international aspects of contract law. Throughout the book, the treatment emphasizes drafting considerations. An introduction in which contracts are defined and contrasted to torts, quasi-contracts, and property is followed by a discussion of the concepts of 'consideration' or 'cause' and other underlying principles of the formation of contract. Subsequent chapters cover the doctrines of 'relative effect', termination of contract, and remedies for non-performance. The second part of the book, recognizing the need to categorize an agreement as a specific contract in order to determine the rules which apply to it, describes the nature of agency, sale, lease, building contracts, and other types of contract. Facts are presented in such a way that readers who are unfamiliar with specific terms and concepts in varying contexts will fully grasp their meaning and significance. Its succinct yet scholarly nature, as well as the practical quality of the information it provides, make this book a valuable time-saving tool for business and legal professionals alike. Lawyers representing parties with interests in Japan will welcome this very useful guide, and academics and researchers will appreciate its value in the study of comparative contract law.
