2933.  (a) It is the intent of the Legislature that persons convicted of a crime and sentenced to the state prison under Section 1170 serve the entire sentence imposed by the court, except for a reduction in the time served in the custody of the Secretary of the Department of Corrections and Rehabilitation pursuant to this section and Section 2933.05.(b) For every six months of continuous incarceration, a prisoner shall be awarded credit reductions from his or her term of confinement of six months. A lesser amount of credit based on this ratio shall be awarded for any lesser period of continuous incarceration. Credit should be awarded pursuant to regulations adopted by the secretary. Prisoners who are denied the opportunity to earn credits pursuant to subdivision (a) of Section 2932 shall be awarded no credit reduction pursuant to this section. Under no circumstances shall any prisoner receive more than six months’ credit reduction for any six-month period under this section.(c) Credit is a privilege, not a right. Credit must be earned and may be forfeited pursuant to the provisions of Section 2932. Except as provided in subdivision (a) of Section 2932, every eligible prisoner shall have a reasonable opportunity to participate.(d) Under regulations adopted by the Department of Corrections and Rehabilitation, which shall require a period of not more than one year free of disciplinary infractions, credit which has been previously forfeited may be restored by the secretary. The regulations shall provide for separate classifications of serious disciplinary infractions as they relate to restoration of credits, the time period required before forfeited credits or a portion thereof may be restored, and the percentage of forfeited credits that may be restored for these time periods. For credits forfeited as specified in paragraph (1) of subdivision (a) of Section 2932, the Department of Corrections and Rehabilitation may provide that up to 180 days of lost credit shall not be restored and up to 90 days of credit shall not be restored for a forfeiture resulting from conspiracy or attempts to commit one of those acts. No credits may be restored if they were forfeited for a serious disciplinary infraction in which the victim died or was permanently disabled. Upon application of the prisoner and following completion of the required time period free of disciplinary offenses, forfeited credits eligible for restoration under the regulations for disciplinary offenses other than serious disciplinary infractions punishable by a credit loss of more than 90 days shall be restored unless, at a hearing, it is found that the prisoner refused to accept or failed to perform in a credit qualifying assignment, or extraordinary circumstances are present that require that credits not be restored. “Extraordinary circumstances” shall be defined in the regulations adopted by the secretary. However, in any case in which credit was forfeited for a serious disciplinary infraction punishable by a credit loss of more than 90 days, restoration of credit shall be at the discretion of the secretary.The prisoner may appeal the finding through the Department of Corrections and Rehabilitation’s review procedure, which shall include a review by an individual independent of the institution who has supervisorial authority over the institution.(e) The provisions of subdivision (d) shall also apply in cases of credit forfeited under Section 2931 for offenses and serious disciplinary infractions occurring on or after January 1, 1983.(Amended by Stats. 2011, 1st Ex. Sess., Ch. 12, Sec. 16. (AB 17 1x) Effective September 21, 2011. Operative October 1, 2011, by Sec. 46 of Ch. 12.)
