(a) Pre-indictment. A complaint may be administratively dismissed by the prosecutor without presentation to the grand jury in which event said prosecutor shall report the dismissal and the basis therefor to the Assignment Judge and shall notify the defendant.
(b) Post-indictment. Upon motion by the prosecuting attorney, an indictment, accusation or complaint, or any count thereof, may be dismissed prior to trial by order of the judge to whom the same has been assigned for trial. During trial an indictment or accusation, or any count thereof may be dismissed by the trial judge on motion by the prosecuting attorney with the consent of the defendant.
A defendant who has remained in custody awaiting trial on an indictment, other than for a capital offense, for at least 90 consecutive days after the return of that indictment may move for a trial date. The motion shall be on notice to the prosecutor and shall be accompanied by a certification that the defense is ready to proceed to trial. The court shall, after affording the prosecutor an opportunity to be heard, fix a date for trial. In the event the prosecutor is unable to proceed on the trial date, the court shall take such action and enter such orders as the interest of justice requires, which may include pretrial release.
If there is an unreasonable delay in presenting the charge to a grand jury or in filing an accusation against a defendant who has been held to answer upon a complaint, the Assignment Judge, or the Assignment Judge's designee, may dismiss the matter sua sponte or on motion of the defendant. If there is unreasonable delay in the disposition of an indictment or accusation, the judge to whom the case has been assigned may dismiss the matter sua sponte or on motion of the defendant.
