The U.S. Supreme Court on Monday ruled for DirecTV Inc, backing the satellite television provider’s efforts to enforce arbitration agreements signed by its customers in California. Consumer advocates have criticized the increased use of such arbitration agreements that they contend deny customers the opportunity to vindicate their rights in court. The high court, on a 6-3 vote, overturned a state appeals court decision in California that found that consumers were not bound by a provision in DirecTV’s customer agreement preventing disputes from being resolved on a class-wide basis.
