Article 6

Unless the parties have already agreed on the choice of an appointing authority, a party may at any time propose the name or names of one or more institutions or persons, including the Secretary-General of the Permanent Court of Arbitration at The Hague (hereinafter called the ‘PCA’), one of whom would serve as appointing authority.

If all parties have not agreed on the choice of an appointing authority within 30 days after a proposal made in accordance with paragraph 1 has been received by all other parties, any party may request the Secretary-General of the PCA to designate the appointing authority.

Where these Rules provide for a period of time within which a party must refer a matter to an appointing authority and no appointing authority has been agreed on or designated, the period is suspended from the date on which a party initiates the procedure for agreeing on or designating an appointing authority until the date of such agreement or designation.

Except as referred to in article 41, paragraph 4, if the appointing authority refuses to act, or if it fails to appoint an arbitrator within 30 days after it receives a party's request to do so, fails to act within any other period provided by these Rules, or fails to decide on a challenge to an arbitrator within a reasonable time after receiving a party's request to do so, any party may request the Secretary-General of the PCA to designate a substitute appointing authority.

In exercising their functions under these Rules, the appointing authority and the Secretary-General of the PCA may require from any party and the arbitrators the information they deem necessary and they shall give the parties and, where appropriate, the arbitrators, an opportunity to present their views in any manner they consider appropriate. All such communications to and from the appointing authority and the Secretary-General of the PCA shall also be provided by the sender to all other parties.

When the appointing authority is requested to appoint an arbitrator pursuant to articles 8, 9, 10 or 14, the party making the request shall send to the appointing authority copies of the notice of arbitration and, if it exists, any response to the notice of arbitration.

The appointing authority shall have regard to such considerations as are likely to secure the appointment of an independent and impartial arbitrator and shall take into account the advisability of appointing an arbitrator of a nationality other than the nationalities of the parties.
