What is the standard of review of an arbitration award?

apply a highly deferential standard of review to the award itself, insofar as our inquiry encompasses the arbitrator's resolution of questions of law or fact. Because the finality of arbitration awards is rooted in the parties' agreement to bypass the judicial system, ordinarily '"[t]he merits of the controversy between the parties are not subject to judicial review."'" (Cooper v. Lavely & Singer Professional Corp., supra, 230 Cal.App.4th at pp. 11-12.)
