Article 16 - Challenge procedure
(1) The parties are free to agree on a procedure for challenging an arbitrator, subject to the provisions of paragraph 16(3) of this Article.
(2) Failing such agreement, a party who intends to challenge an arbitrator shall, within fifteen days after becoming aware of the constitution of the
Arbitral Panel or after becoming aware of any circumstance referred to in Article 15(2), send a written statement of the reasons for the challenge to the Arbitral Panel. Unless the challenged arbitrator withdraws from his office or the other party agrees to the challenge, the Arbitral Panel shall decide on the challenge.
(3) If a challenge under any procedure agreed upon by the parties or under the procedure of paragraph 16(2) of this Article is not successful, the challenging party may request, within thirty days after having received notice of the decision rejecting the challenge, the
QFC Tribunal to decide on the challenge, which decision shall be subject to no appeal; while such a request is pending, the Arbitral Panel, including the challenged arbitrator, may continue the arbitral proceedings and make an Award.
