Criminal Procedure

Rule 21.3 – Failure to Join Related Offenses

(a) Two (2) or more offenses are related offenses for the purposes of this rule if they are within the jurisdiction and venue of the same court and are based on the same conduct or arise from the same criminal episode.
(b) When a defendant has been charged with two (2) or more related offenses, his timely motion to join them for trial shall be granted unless the court determines that because the prosecuting attorney does not have sufficient evidence to warrant trying some of the offenses at that time, or for some other reason, the ends of justice would be defeated if the motion is granted. A defendant’s failure to so move constitutes a waiver of any right of joinder as to related offenses with which the defendant knew he was charged.
(c) A defendant who has been tried for one (1) offense may thereafter move to dismiss a charge for a related offense, unless a motion for joinder of these offenses was previously denied or the right of joinder was waived as provided in subsection (b). The motion to dismiss must be made prior to the second trial, and shall be granted unless the court determines that because the prosecuting attorney did not have sufficient evidence to warrant trying this offense at the time of the first trial, or for some other reason, the ends of justice would be defeated if the motion were granted.
(d) Entry of a plea of guilty or nolo contendere to one (1) offense does not bar the subsequent prosecution of a related offense. A defendant may enter a plea of guilty or nolo contendere on the basis of a plea agreement in which the prosecuting attorney agrees to seek or not to oppose dismissal of other related charges or not to prosecute other potential related charges.
