What is the legal test for judicial review of a final decision or order rendered by an administrative agency?

"Section 1094.5 of the Code of Civil Procedure governs judicial review by administrative mandate of any final decision or order rendered by an administrative agency. A trial court's review of an adjudicatory administrative decision is subject to two possible standards of review depending upon the nature of the right involved. [Citation.] If the administrative decision substantially affects a fundamental vested right, the trial court must exercise its independent judgment on the evidence. [Citations.] The trial court must not only examine the administrative record for errors of law, but must also conduct an independent review of the entire record to determine whether the weight of the evidence supports the administrative findings. [Citation.] If, on the other hand, the administrative decision neither involves nor substantially affects a fundamental vested right, the trial court's review is limited to determining whether the administrative findings are supported by substantial evidence."
