What is the test for a judicial review of a final order or decision rendered by a state or local agency?

"Section 1094.5 of the Code of Civil Procedure provides the basic framework by which an aggrieved party to an administrative proceeding may seek judicial review of any final order or decision rendered by a state or local agency." (Bixby v. Pierno (1971) 4 Cal.3d 130, 137, fn. omitted.) Section 1094.5, subdivision (a) applies to review of "any final administrative order or decision made as the result of a proceeding in which by law a hearing is required to be given, evidence is required to be taken, and discretion in the determination of facts is vested in the inferior tribunal, corporation, board, or officer."
