Chateau, a Canadian winery, contracted over the phone to buy 1.2 million wine corks from Sabate USA, the U.S. subsidiary of Sabate France. The parent company shipped the corks from France to Canada, along with a pre-printed invoice. The invoice contained a forum selection clause providing that any dispute would be heard in a French court. When Chateau realized that the corks altered the taste of its wine, it sued Sabate in California for breach of contract. Chateau argued that the forum selection clause was not part of the original deal. Furthermore, it had an enforceable oral agreement with Sabate USA, which was governed by the CISG because both Canada and the United States were signatories. Did the CISG govern the dealings between Chateau and Sabate USA? If so, did the contract between Chateau and Sabate USA have to be in writing? Was the forum selection clause enforceable against Chateau?
