If two or more charging documents are filed against the same defendant for the same offense in different courts, and if each court has jurisdiction, the court in which the first charging document was filed shall try the case. Upon motion by either party, or the court, the second or several charging documents shall be forwarded for consolidation and trial to the court in which a charging document was first filed.
