(a) Except as provided in subsections (b) and (c) of this section, any person sentenced to a term of imprisonment, on and after October 1, 1976, and while still serving such sentence whether such sentence is for a definite, indefinite or indeterminate term, and regardless of the institution wherein the prisoner is confined may, by good conduct and obedience to the rules which have been established for the service of his sentence, earn a commutation or diminution of his sentence in the amount of ten days for each month, and pro rata for a part of a month, of a sentence which is for not more than five years, and fifteen days for each month, and pro rata for a part of a month, for the sixth and each subsequent year of a sentence of more than five years. In the case of an indeterminate sentence, such credit shall apply to both the minimum and maximum term. In the case of an indefinite sentence, such credit shall apply to the maximum term only. Any act of misconduct or refusal to obey the rules which have been established for the service of his sentence shall subject the prisoner to the loss of all or any portion of such credit by the commissioner or his designee.

(b) Except as provided in subsection (c) of this section, any person sentenced to a term of imprisonment for an offense committed on or after July 1, 1981, may, while held in default of bond or while serving such sentence, by good conduct and obedience to the rules which have been established for the service of his sentence, earn a reduction of his sentence in the amount of ten days for each month and pro rata for a part of a month of a sentence up to five years, and twelve days for each month and pro rata for a part of a month for the sixth and each subsequent year of a sentence which is more than five years. Misconduct or refusal to obey the rules which have been established for the service of his sentence shall subject the prisoner to the loss of all or any portion of such reduction by the commissioner or his designee.

(c) Any person sentenced to a term of imprisonment for an offense committed on or after July 1, 1983, may, while held in default of bond or while serving such sentence, by good conduct and obedience to the rules which have been established for the service of his sentence, earn a reduction of his sentence as such sentence is served in the amount of ten days for each month served and pro rata for a part of a month served of a sentence up to five years, and twelve days for each month served and pro rata for a part of a month served for the sixth and each subsequent year of a sentence which is more than five years. Misconduct or refusal to obey the rules which have been established for the service of his sentence shall subject the prisoner to the loss of all or any portion of such reduction by the commissioner or his designee. In the event a prisoner has not yet earned sufficient good time to satisfy the good time loss, such lost good time shall be deducted from any good time earned in the future by such prisoner.

(a) and (b) by making technical changes.

Section satisfies the rational basis test consistent with command of the equal protection clause. 176 C. 638. Held that credits be calculated according to statute in effect at time of resentencing rather than according to statute effective at time of original sentence. 185 C. 124. Cited.

Prospective forfeiture of unearned good time credit is not permitted. 209 C. 191. Statutory good time calculation and credit discussed. 219 C. 269. Two statements in Seno v. Commissioner of Correction were factually and legally inaccurate, thus trial court decision construing Subsec. (b) based in part on Seno was inaccurate. 245 C. 423. “One continuous term” language of Sec. 18-7 is applicable to Subsec. and good time credits earned on an earlier sentence must be credited towards a controlling, subsequently imposed concurrent sentence. 254 C. 214.

Good time credit received under section must be interpreted as credit earned in the year it should have been given and in this case, adjustment of respondent's time was not a retroactive adjustment, but rather a correction. 86 CA 777. Habeas court found to have improperly determined that petitioner was not eligible for good time credits; court's interpretation of good time statutes has the potential of burdening defendant in such a manner so as to conclude that the statutes are penal in nature; in resolving a latent ambiguity as to whether defendant was eligible for good time credits, the rule of lenity applied. 101 CA 52. Viewed within context of section, the phrase “term of imprisonment” is susceptible only to one reasonable interpretation, which is that it should be afforded its customary and primary meaning, describing the physical confinement of a person in a correctional facility; there is no basis in law or logic to conclude that it describes or encompasses time spent on probation. 105 CA 210.
