Frank Boomer received a contract in the mail from his long-distance carrier, AT&T, that stated in unambiguous language that his rates were changing and that he should contact AT&T immediately if this was not acceptable. The agreement also contained a clause stating that any dispute concerning the contract would be settled by binding arbitration. Boomer did nothing initially and continued to make long-distance calls. Later, he decided to file a classaction suit against AT&T for overcharging him and other customers. Will Boomer be successful in getting his case heard by a court instead of an arbitrator? [Boomer v. AT&T Corp., 309 F.3d 404 (7th Cir. 2002).]
