Parole hearings may not be held for inmates confined in a State mental hospital, unless the Commission, in its discretion, and upon the recommendation of the Maryland Department of Health, elects to hold a parole hearing at the State mental hospital where the inmate resides. Whenever an inmate is transferred back to the Department of Correction by the Maryland Department of Health, a hearing will be scheduled on the date set by the Commission at any prior parole hearing. If there has been no prior parole hearing, a hearing will be scheduled at the expiration of one-fourth of the sentence. If the transfer occurs subsequent to this date, the hearing shall be held at the next meeting of the Commission at the place of confinement.
