(a) This section applies to persons released from state prison on or after July 1, 2020, and who are subject to the jurisdiction of, and parole supervision by, the Department of Corrections and Rehabilitation pursuant to Section 3000.08 of the Penal Code.
(b) Except as provided in subdivision (d) and notwithstanding any other law, persons described in subdivision (a) shall serve a parole term as follows:
1. (1) Any inmate sentenced to a determinate term shall be released on parole for a period of two years. The inmate will be reviewed by the Division of Adult Parole Operations for possible discharge from parole no later than 12 months after release from confinement. If at the time of the review the inmate has been on parole continuously for 12 months since release from confinement without a violation and the inmate is not a person required to be treated as described in Section 2962, the inmate shall be discharged from parole.
2. (2) Any inmate sentenced to a life term shall be released on parole for a period of three years. The inmate will be reviewed by the Division of Adult Parole Operations and referred to the Board of Parole Hearings for possible discharge from parole no later than 12 months after release from confinement. If the Board of Parole Hearings determines the inmate should be retained on parole, the inmate will be reviewed again and referred to the Board of Parole Hearings for possible discharge from parole no later than 24 months after release from confinement.
(c) Upon successful completion of parole, or at the end of the maximum statutory period of parole specified in this section, whichever is earlier, the inmate shall be discharged from parole. The date of the maximum statutory period of parole under this section shall be computed from the date of initial parole and shall be a period chronologically determined. Time during which parole is suspended because the inmate has been returned to custody as a parole violator shall not be credited toward any period of parole unless the inmate is found not guilty of the parole violation.
1. (1) Except as provided in paragraph (4) of subdivision (a) of Section 3000 and Section 3064, in no case may an inmate who is released on parole for a period of two years be retained under parole supervision or in custody for a period longer than three years from the date of their initial parole.
