The Supreme Court of the United States announced one decision this morning:

AT&T Mobility v. Concepcion, No. 09-893: Respondents' cellular telephone contract provided for arbitration of disputes, but did not permit class arbitration. When respondents sued AT&T and AT&T sought to compel arbitration, the district court denied the motion to compel and the Ninth Circuit affirmed, finding the arbitration provision unconscionable under California law because it disallowed classwide arbitration. Today the Supreme Court held that the California law is preempted by the Federal Arbitration Act, and the case was remanded.
