(1) Any party other than the state may appeal from a judgment of the court to the supreme court in the manner provided by law. The appeal shall be heard by the supreme court upon the files, records, and transcript of the evidence of the juvenile court.
(2) The appeal to the supreme court does not stay the judgment appealed from, but the supreme court may order a stay upon application and hearing consistent with the provisions of this chapter if suitable provision is made for the care and custody of the youth. If the order appealed from grants the legal custody of the youth to or withholds it from one or more of the parties to the appeal, the appeal shall be heard at the earliest practicable time.
