For the sole purposes of the application of the provisions of Articles 25 and 26, and of the domestic laws of the Contracting States, concerning the communication and the confidentiality of the information related to the case that results in the arbitration process, each arbitrator shall be designated as authorised representative of the competent authority that has appointed that arbitrator or, if that arbitrator has not been appointed exclusively by one competent authority, of the competent authority of the Contracting State to which the case giving rise to the arbitration was initially presented. For the purposes of this agreement, where a case giving rise to arbitration was initially presented simultaneously to both competent authorities, “the competent authority of the Contracting State to which the case giving rise to the arbitration was initially presented” means the competent authority referred to in paragraph 1 of Article 25.
