The result was the New York Arbitration Act of 1920, followed by the United States Arbitration Act of 1925 (now known as the Federal Arbitration Act). Both made agreements to arbitrate valid and enforceable (unless one party could show fraud or unconscionability or some other ground for rescission which undermined the validity of the entire contract). Due to the subsequent judicial expansion of the meaning of interstate commerce, the U.S. Supreme Court reinterpreted the FAA in a series of cases in the 1980s and 1990s to cover almost the full scope of interstate commerce. In the process, the Court held that the FAA preempted many state laws covering arbitration, some of which had been passed by state legislatures to protect their consumers against powerful corporations.
