When will a parole board make a parole decision that does not require a judicial review?

²Absent this state-created expectancy, parole decisions do not implicate due process concerns. Decisions of the Executive Branch, however serious their impact, do not automatically invoke due process protection; there simply is no constitutional guarantee that all executive decisionmaking must comply with standards that assure error-free determinations. [Citations.] This is especially true with respect to the sensitive choices presented by the administrative decision to grant parole release. ( Greenholtz v. Nebraska Penal Inmates, supra, 442 U.S. at p. 7, 99 S.Ct. 2100.)
