If the prosecution has imposed a plea deadline in a case in which an indictment or information has been filed in Superior Court, but does not provide the defense with material disclosure listed in Rule 15.1(b) at least 30 days prior to the plea deadline, the court, upon motion of the defendant, shall consider the impact of the failure to provide such disclosure on the defendant's decision to accept or reject a plea offer. If the court determines that the prosecutor's failure to provide such disclosure materially impacted the defendant's decision and the prosecutor declines to reinstate the lapsed plea offer, the presumptive minimum sanction shall be preclusion from admission at trial of any evidence not disclosed at least 30 days prior to the deadline.
