Obtained reversal of a trial court decision confirming arbitration award against a non-signatory to an arbitration agreement on the grounds that the non-signatory was the alter ego of the signatory corporation and the rules of the arbitral forum vested arbitrability decisions with the arbitrator; clarified that under California law the question of whether a non-signatory is bound by an arbitration agreement is always a question for the courts, even in instances in which the arbitration agreement or the rules of the tribunal delegate arbitrability questions to the arbitrator. Benaroya v. Willis, 23 Cal. App. 5th 462 (2018).
