Administrative Litigation Act Article 228-2

When a party to the litigation has the right to dispose of the subject matter of the litigation, and the mediation of the litigation does not harm the public interest, the administrative court may, at the consent of both parties to the litigation, move the case to mediation when the case is pending. The commissioned or assigned judge of the administrative court may also attempt to mediate the case, as referred to in the preceding Paragraph.When necessary, mediation may include matters that are not the subject matter of the litigation.With permission granted by the administrative court, a third party may participate in the mediation. If the administrative court considers it necessary, it may instruct a third party to participate in mediation on its initiative or upon the application of a party.
