(b) The commutation of sentence, known as “good time”, shall be deducted from the maximum term of indeterminate sentences or from the fixed term of determinate sentences.

(c) Each inmate committed to the custody of the commissioner and incarcerated in a facility pursuant to that commitment shall be granted one day good time for each day he or she is incarcerated, including any and all days in jail awaiting sentence which are credited by the sentencing court to his or her sentence pursuant to §61-11-24 of this code or for any other reason relating to the commitment. An inmate may not be granted any good time for time served either on parole or bond or in any other status when he or she is not physically incarcerated.

(d) An inmate sentenced to serve a life sentence is not eligible to earn or receive any good time pursuant to this section.

The rules and policies shall describe acts that inmates are prohibited from committing, procedures for charging individual inmates for violation of the rules, and for determining the guilt or innocence of inmates charged with the violations, and the sanctions which may be imposed for the violations. A copy of the rules shall be given to each inmate. For each violation, by a sanctioned inmate, any part or all of the good time which has been granted to the inmate pursuant to this section may be forfeited and revoked by the superintendent of the institution in which the violation occurred. The superintendent when appropriate and with approval of the commissioner, may restore any forfeited good time.

(k) Prior to the calculated discharge date of an inmate serving a sentence for a felony crime of violence against the person, a felony offense where the victim was a minor child or a felony offense involving the use of a firearm, one year shall be deducted from the inmate’s accumulated good time to provide for one year of mandatory post-release supervision following the first instance in which the inmate reaches his or her calculated discharge date. All inmates released pursuant to this subsection shall be subject to electronic or GPS monitoring for the entire period of supervision. The provisions of this subsection are applicable to offenses committed on or after July 1, 2013.

(l) Upon sentencing of an inmate for a felony offense not referenced in §15A-4-17(k) of this code, the court may order that 180 days of the sentence, or some lesser period, be served through post-release mandatory supervision if the court determines supervision is appropriate and in the best interest of justice, rehabilitation, and public safety. All inmates released pursuant to this subsection shall be subject to electronic or GPS monitoring for the entire period of supervision. The provisions of this subsection are applicable to offenses committed on or after July 1, 2013.

(m) The commissioner shall adopt policies and procedures to implement the mandatory supervision provided for in §15A-4-17(k) and §15A-4-17(l) of this code, which may include terms, conditions, and procedures for supervision, modification, and violation applicable to persons on parole.
