Article 14 Challenge of Arbitrators

A challenge of an arbitrator, whether for an alleged lack of impartiality or independence, or otherwise, shall be made by the submission to the Secretariat of a written statement specifying the facts and circumstances on which the challenge is based.

For a challenge to be admissible, it must be submitted by a party either within 30 days from receipt by that party of the notification of the appointment or confirmation of the arbitrator, or within 30 days from the date when the party making the challenge was informed of the facts and circumstances on which the challenge is based if such date is subsequent to the receipt of such notification.

The Court shall decide on the admissibility and, at the same time, if necessary, on the merits of a challenge after the Secretariat has afforded an opportunity for the arbitrator concerned, the other party or parties and any other members of the arbitral tribunal to comment in writing within a suitable period of time. Such comments shall be communicated to the parties and to the arbitrators.
