Book excerpt: This book describes and analyses the rules and provisions of the United Nation Convention on the International Sale of Goods of 1980 - CISG-. The authors explain the details of the CISG’s text, report the essence of the scholarly discussions of its issues, and, in particular, present numerous cases decided by courts and arbitration tribunals both as illustrations of problems arising under the CISG and as case law interpreting the Convention. The book is mainly intended to be used in teaching, but it can also help practitioners to understand the structure and basic solutions of sales law issues encoded in the CISG.
