Sec. 13. (a) Upon motion of the prosecuting attorney, the court shall order the dismissal of the indictment or information. The motion may be made at any time before sentencing and may be made on the record or in writing. The motion shall state the reason for dismissal.
(b) In any case where an order sustaining a motion to dismiss would otherwise constitute a bar to further prosecution of the crime charged, unless the defendant objects to dismissal, the granting of the motion does not bar a subsequent trial of the defendant on the offense charged.
