N.D. Cent. Code § 12-47-25: Punishment for infraction may be alleviated

Whenever any inmate who is being punished for any infraction of the rules and regulations of the penitentiary by being deprived of any of the ordinary privileges enjoyed by the other inmates, periodically or otherwise, conducts himself in a peaceful, obedient, and industrious manner, the warden may suspend the further infliction of such punishment during his good behavior.
