The contributors to this volume, well-known experts from Europe and the US, analyze various issues relating to the United Nations Convention on Contracts for the International Sale of Goods (CISG). With its current global network of 58 Contracting States, the CISG is widely applied in practice today. To make the growing case law on this subject matter readily accessible, the UNCITRAL Secretariat in Vienna has set up a reporting system for national court decisions relating to the CISG. The extensive documentation already collected there and elsewhere will surely have a lasting impact on the ongoing scholarly debate on this topic. The present book is intended to contribute to this debate by addressing controversial issues relating to the interpretation and application of some important provisions of the new sales law. In addition, several authors also deal with the development of international principles of contract law, such as the Principles of European Contract Law, the UNIDROIT Principles and the lex mercatoria . In view of the increasing number of such rules, a discussion of the CISG would be incomplete without taking account of the relationship of the Convention to these principles as well.
