If an inmate, including an inmate whose sentence is subject to sections 12.1-32-02.1 and 12.1-32-09.1, and an inmate sentenced under subsection 1 of section 12.1-32-01, has a serious or terminal medical condition, the parole board may grant the inmate a medical parole. An inmate who receives a medical parole remains under the jurisdiction of the parole board until the expiration of the maximum term or terms of imprisonment for which the inmate was sentenced, less any sentence reduction the inmate has received.
