Under CCP 1281.4, a court may stay an action in court pending arbitration “of a controversy which is an issue involved” in the action. This decision holds that the statute does not apply unless the court has ordered parties in the judicial action to arbitration, the arbitrable issue arises in the pending court action, and the parties in the arbitration are also parties to the court action. A court may not stay a party’s court action merely because an issue in that action is being decided in one or more arbitrations involving only one of the two parties to the court action. Here, plaintiff brought a PAGA suit raising an issue that was being arbitrated by the defendant in 50 different arbitration proceedings. Nevertheless, since plaintiff wasn’t a party to any of those arbitrations, the trial court had no authority to stay the plaintiff’s PAGA suit.
