If a district administrative court adjudicates an ordinary proceeding case through small claims proceeding or traffic adjudication proceeding, or if a district administrative court adjudicates a small claims case through a traffic adjudication proceeding, the high administrative court adjudicating the appeals shall rescind the original judgment and remand the case to the district administrative court with jurisdiction.

Except otherwise provided for in Article 259-1 and this Chapter, Chapter 1 of this Part and Chapter 1 of the preceding Part apply mutatis mutandis to the appellate trial proceedings of high administrative courts. In addition, Article 237-8 applies to the appeals of traffic adjudication cases.
