If both a prosecuting attorney and the attorney general file an information or indictment charging a defendant with substantially the same offense(s), the court shall, upon motion of either the prosecuting attorney or the attorney general:
(1) Determine whose prosecution of the case will best promote the interests of justice and enter an order designating that person as the prosecuting authority in the case; and
(2) Enter an order dismissing the information or indictment filed by the person who was not designated the prosecuting authority.
