Contracts for the Sale of Goods delivers detailed analysis and in-depth comparison of the substantive law for the sale of goods in domestic and international transactions. It provides comparative analysis of three major sources of sales law: The United Nations Convention on Contracts for the Sale of Goods, the UNIDROIT Principles of International Commercial Contracts (PICC), and the Sales of the Uniform Commercial Code.Practitioners, academics, and anyone involved in the sale or purchase of goods in the international market will need this thorough analysis of both the text of the United Nations Convention on Contracts for the International Sale of Goods (CISG) and the cases that have addressed and interpreted the CISG. The new edition examines the number of American cases on the CISG decided since the last edition, and the several hundred major non-American CISG cases, concentrating on the development of specific points of law that have become important and contentious areas. It continues to provide a complete discussion of the PICC including the latest provisions on set-off, assignment, and limitation periods, and timely coverage of the new supplementary model clauses for use with the Principles. This is the only text that compares and analyses the PICC, the CISG and the Uniform Commercial Code in a detailed way. It explores instances when one may be more applicable than the other, and enables further understanding of all three instruments and the options available under international and domestic US law.
