03-208-1 Me. Code R. § VI
An individual's parole is terminated on his parole discharge date, which is mathematically determined in accordance with sentence and institutional good conduct deductions. A prisoner paroled on a life sentence must successfully complete ten (10) years of supervision before discharge ( 34-A M.R.S.A. §5809) . However, the Board may otherwise discharge a parolee before his parole discharge date if it appears that the person is no longer in need of supervision. Either a parole officer or a parolee may request that the Board grant an early discharge by contacting the Board in writing stating the reasons for such request ( 34-A M.R.S.A. §5809) .
Normally, the Board will not discharge a parolee unless he successfully abides by the conditions of his parole for a period of at least one year. The Board considers discharges in less than one year under special circumstances.
Once a decision is made granting early discharge, the Board shall notify the appropriate institution of the discharge, stating the reason for the discharge (Form entitled, "Authorization to Discharge Parolee", Appendix page 39).
