Where appeal to the district court from an action or decision of any officer, body or board is provided for by statute and the statute does not provide for the formulation of the issues either before such officer, body or board, or in the district court, the appellant shall file a petition in the district court within ten days after perfecting the appeal, or within such time as may be prescribed by the court. The appellee shall file motion or an answer to such petition within 20 days thereafter, or within such further time as may be prescribed by the court. Thereafter the rules of pleading and procedure in actions in the district court shall be applicable.
