In 1980, the United Nations Convention for the International Sale of Goods (CISG) came into being as an attempt to create a uniform commercial sales law. This book, first published in 2007, compares two major restatements - the UNIDROIT Principles and the Principles of European Contract Law (PECL) - with CISG articles. This work has gathered scholars and legal practitioners from twenty countries who contribute analysis on the various issues covered in the articles of the CISG comparing them with how the issue is treated in the UNIDROIT and PECL restatements.The introductory section of the book addresses theoretical and practical issues of the appropriate interpretive methodology as mandated in CISG Article 7 and it is followed by individual analyses of the Convention's provisions.
