AT&T Mobility v. Concepcion
Holding
California state contract law, which deems class-action waivers in arbitration agreements unenforceable when certain criteria are met, is preempted by the Federal Arbitration Act because it stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress.
Plain English Holding
Under the Federal Arbitration Act, California must enforce arbitration agreements even if the agreement requires that consumer complaints be arbitrated individually (instead of on a class-action basis).
Judgment
Ninth Circuit Reversed, 5-4, in an opinion by Antonin Scalia on Apr 27, 2011. Justice Thomas filed a concurring opinion. Justice Breyer filed a dissenting opinion, which was joined by Justices Ginsburg, Sotomayor, and Kagan.
