What is the standard of review in a motion seeking to overturn a decision by the Court of Appeal allowing an inmate to stay in prison pending his release date?

Respondent's argument to the contrary is unpersuasive. Respondent draws an analogy to the standard of review in administrative mandamus actions, in which the trial court must exercise its independent judgment on the evidence when an administrative decision has affected a vested right. (See, e.g., Bixby v. Pierno (1971) 4 Cal.3d 130, 144-146, 93 Cal.Rptr. 234, 481 P.2d 242.) The fatal flaw in the analogy is that a prison inmate has no vested right in his or her prospective liberty on a parole release date. (Fain I, supra, 65 Cal.App.3d at p. 390, 135 Cal.Rptr. 543.)
