Cal. Pen. Code § 2977
A person committed to the care of the State Department of State Hospitals because he or she is a mentally disordered offender, including a person who is found not guilty by reason of insanity, is eligible for compassionate release pursuant to Section 4146 of the Welfare and Institutions Code. In any case in which the criteria for compassionate release apply, the State Department of State Hospitals shall follow the procedures and standards in Section 4146 of the Welfare and Institutions Code to determine if the department should recommend to the court that the person's commitment be suspended for compassionate release. This section applies to persons committed for treatment during parole and persons committed pursuant to Section 2970. If the person for whom compassionate release is recommended is on parole, notice shall be given to the Board of Parole Hearings.
