California Code, Penal Code - PEN § 3041.1

(a) Any time before an inmate's release, the Governor may request review of a decision by a parole authority concerning the grant or denial of parole to any inmate in a state prison.  The Governor shall state the reason or reasons for the request, and whether the request is based on a public safety concern, a concern that the gravity of current or past convicted offenses may have been given inadequate consideration, or on other factors.

(b) If a request has been made, the request shall be reviewed by a majority of commissioners specifically appointed to hear adult parole matters and who are holding office at the time.  In case of a review, a vote in favor of parole by a majority of the commissioners reviewing the request shall be required to grant parole to any inmate.  In carrying out any review, the board shall comply with this chapter.
