Idaho Criminal Rule 54.3. Time for Filing Appeals.
(a) All appeals permitted or authorized by these rules, may be made only by the physical filing of a notice of appeal with the clerk of the district court of the county wherein the magistrate trial was held, within forty-two (42) days from the date evidenced by the filing stamp of the clerk of the court on the judgment, order or decree appealed. The time to appeal from any criminal judgment, order or decree in an action is terminated by the filing of a motion within fourteen (14) days of the entry of the judgment which, if granted, could affect the judgment or sentence in the action, in which case the appeal period commences to run upon the date of the clerk's filing stamp on the order deciding such motion.
(b) Time for filing cross-appeal. When a timely appeal is filed as matter of right, a cross-appeal may be filed by the opposing party within the time prescribed by these rules or within fourteen (14) days from the date the original notice of appeal is served, whichever is later.
