Rhode Island General Laws Title 13. Criminals--Correctional Institutions § 13-8-10. Prisoners subject to more than one sentence

(a) If a prisoner is confined upon more than one sentence, a parole permit may be issued whenever he or she has served a term equal to one-third ( 1/3 ) of the aggregate time which he or she shall be liable to serve under his or her several sentences, unless he or she has been sentenced to serve two (2) or more terms concurrently, in which case the permit shall be issued when he or she has served a term equal to one-third ( 1/3 ) of the maximum term he or she is required to serve.

(b) If a prisoner, whether in confinement or on parole, is sentenced to serve a term of imprisonment for an offense which was committed after imposition of the sentence then being served, a permit may not be issued until he or she has served in confinement at least one-third ( 1/3 ) of the term of imprisonment to which he or she is sentenced for the subsequent offense. In calculating the date the prisoner shall become eligible for a permit, the time spent in confinement on an earlier imposed concurrent sentence shall not be credited for the purposes of parole eligibility on the subsequent sentence. In the event a prisoner is convicted of two (2) or more subsequent offenses and is sentenced to multiple terms of imprisonment for those offenses, the standards contained in subsection (a) of this section shall be used to determine when he or she has served one-third ( 1/3 ) of the terms of confinement imposed for the subsequent offenses and thereby is eligible for issuance of a permit under this subsection.
