1. If a prisoner is sentenced pursuant to NRS 176.035 to serve two or more concurrent sentences, whether or not the sentences are identical in length or other characteristics, eligibility for parole from any of the concurrent sentences must be based on the sentence which requires the longest period before the prisoner is eligible for parole.
2. Notwithstanding any other provision of law, if a prisoner is sentenced pursuant to NRS 176.035 to serve two or more consecutive sentences of life imprisonment with the possibility of parole:
(a) For offenses committed on or after July 1, 2009, but before July 1, 2014:
(1) All minimum sentences for such offenses must be aggregated;
(2) The prisoner shall be deemed to be eligible for parole from all such sentences after serving the minimum aggregate sentence; and
(3) The Board is not required to consider the prisoner for parole until the prisoner has served the minimum aggregate sentence.
(b) For offenses committed before July 1, 2009, in cases in which the prisoner has not previously been considered for parole for any such offenses:
(1) The prisoner may, by submitting a written request to the Director of the Department of Corrections before July 1, 2014, make an irrevocable election to have the minimum sentences for such offenses aggregated; and
(2) If the prisoner makes such an irrevocable election to have the minimum sentences for such offenses aggregated, the Board is not required to consider the prisoner for parole until the prisoner has served the minimum aggregate sentence.
