Order or decision when state appeals.

(1) When the state appeals from an order dismissing an indictment, information, or affidavit, or a count of it, or an order granting a new trial and the order is affirmed, the appellate court shall direct the trial court to implement the order. If an order dismissing an indictment, information, or affidavit, or a count of it, is reversed, the appellate court shall direct the trial court to permit the defendant to be tried on the reinstated indictment, information, or affidavit. If an order granting a new trial is reversed, the appellate court shall direct that judgment of conviction be entered against the defendant.

(2) A cross-appeal by the state is not jurisdictional. When the state cross-appeals from a ruling on a question of law adverse to the state, the appellate court shall decide the question if it is reasonably capable of repetition in any proceeding.
