How have the facts been determined in a personal injury case?

1 The facts stated are taken primarily from the arbitrator's award and memoranda of decision. As the parties recognize, courts may not review for sufficiency the evidence supporting an arbitrator's award. (Moncharsh v. Heily & Blase, supra, 3 Cal.4th at p. 11, 10 Cal.Rptr.2d 183, 832 P.2d 899.) We therefore take the arbitrator's findings as correct without examining a record of the arbitration hearings themselves; indeed, the appellate record contains neither a reporter's transcript of the hearings nor the exhibits introduced therein.
