In Faulkner v. Cal. Toll Bridge Authority (1953) 40 Cal.2d 317, the court reiterated the high burden with which respondents approach the court: "'The findings and the determination come before the reviewing court with a strong presumption as to their correctness and regularity. Thus, it is presumed, in the absence of evidence establishing . . . the contrary, that the necessary facts to support the determination were ascertained and found, that the agency duly considered the evidence adduced at the administrative hearing, that official duty was regularly performed, and that the agency applied the proper standard or test in reaching its decision.'" (Id., at p. 330.)
