Article 1124: Constitution of a Tribunal When a Party Fails to Appoint an Arbitrator or the Disputing Parties Are Unable to Agree on a Presiding Arbitrator

1. The Secretary-General shall serve as appointing authority for an arbitration under this Section.

2. If a Tribunal, other than a Tribunal established under Article 1126 (TLCAN: Art. 1126), has not been constituted within 90 days from the date that a claim is submitted to arbitration, the Secretary-General, on the request of either disputing party, shall appoint, in his discretion, the arbitrator or arbitrators not yet appointed, except that the presiding arbitrator shall be appointed in accordance with paragraph 3.

3. The Secretary-General shall appoint the presiding arbitrator from the roster of presiding arbitrators referred to in paragraph 4, provided that the presiding arbitrator shall not be a national of the disputing Party or a national of the Party of the disputing investor. In the event that no such presiding arbitrator is available to serve, the Secretary-General shall appoint, from the ICSID Panel of Arbitrators, a presiding arbitrator who is not a national of any of the Parties.

4. On the date of entry into force of this Agreement, the Parties shall establish, and thereafter maintain, a roster of 45 presiding arbitrators meeting the qualifications of the Convention and rules referred to in Article 1120 (TLCAN: Art. 1121) and experienced in international law and investment matters. The roster members shall be appointed by consensus and without regard to nationality.
