Administrative Litigation Act Article 185

The fact that both parties failed to appear in the oral-argument sessions without giving a justifiable reason will be deemed a consent to stay the proceeding, unless the stay is detrimental to protecting the public interest. If the parties fail to continue the proceeding within four months thereafter, the case will be deemed dismissed involuntarily. Nonetheless, the administrative court may, as it considers necessary, continue the proceeding on its own initiative.When the administrative court orders to continue the litigation in accordance with the proviso of the preceding Paragraph, if both parties still fail to appear without giving a justifiable reason, the case shall be deemed dismissed voluntarily.When the administrative court deems that the stay of proceeding as provided in the first Paragraph is detrimental to protecting the public interest, unless otherwise provided in applicable laws, the court shall order by a ruling to continue the action within one month after such date.No appeal may be taken from the ruling provided in the preceding Paragraph.
