In this matter of first impression, the court considered whether the holding in State v. Cain, 224 N.J. 410 (2016), prohibiting expert witnesses from opining on a defendant's state of mind in drug cases, should also apply to grand jury proceedings. The court concluded that Cain's holding does apply to grand jury proceedings because concerns about the prejudicial effect of such testimony on petit jury deliberations are equally present during one-sided grand jury presentations, if not more so. Consequently, the court reversed in part the trial court order denying defendant's motion to dismiss the indictment charging defendant with numerous drug-distribution related offenses and remanded for further proceedings because a police officer testified before the grand jury, based on his training and experience, that defendant had possessed controlled dangerous substances with the intent to distribute them.
