Any order granting, denying, renewing, or revoking any license under the provisions of this chapter may be appealed to the district court of the county in the same manner as appeals from any order under the zoning ordinance of the city. Appeals must be taken within ten days after the order is issued. Upon any such appeal, the findings of fact of the city commission, if supported by substantial evidence, shall be conclusive. (Prior code § 19-9).
