2006 Massachusetts Code - Chapter 127 — Section 133B. Parole of prisoners declared to be habitual criminals;conditions;revision; revocation.

Section 133B. In the case of every prisoner sentenced under the provisions of section twenty-five of chapter two hundred and seventy-nine except for those persons sentenced to a term of imprisonment as prescribed by the sentencing guidelines established by the sentencing commission, the parole board shall, within sixty days before the expiration of half of his maximum sentence, and thereafter at least once in each ensuing two-year period, consider carefully and thoroughly the merits of such case on the question of releasing such person on parole. After such consideration, the parole board may grant to such prisoner a parole permit to be at liberty upon such terms and conditions as it may prescribe for the unexpired term of his sentence. Such terms and conditions may be revised, altered and amended, and may be revoked by the parole board at any time. The violation by the holder of such permit of any of its terms or conditions, or of any law of the commonwealth, shall render such permit void, and thereupon, or if such permit has been revoked, the parole board may order his arrest and his return to prison, in accordance with the provisions of section one hundred and forty-nine. The period which must be served before such prisoner becomes eligible for parole shall be calculated with deductions applicable to other sentences for good conduct.
