Today, the Seventh Circuit affirmed summary judgment against an automobile manufacturer that tried to compel a dealer to arbitrate their dispute under a contract that expired before the dispute arose. Nissan argued that the parties’ continuing to do business after contract expiration somehow revived the arbitration clause in the contract. The district court didn’t buy it, and neither did the Seventh Circuit. Nissan N. Am., Inc. v. Jim M’Lady Oldsmobile, Inc. , No. 05-1786 (7th Cir. May 11, 2007).
