Article 39

1. The fees of the arbitral tribunal shall be reasonable in amount, taking into account the amount in dispute, the complexity of the subject-matter, the time spent by the arbitrators and any other relevant circumstances of the case.

2. If an appointing authority has been agreed upon by the parties or designated by the Secretary-General of the Permanent Court of Arbitration at The Hague, and if that authority has issued a schedule of fees for arbitrators in international cases which it administers, the arbitral tribunal in fixing its fees shall take that schedule of fees into account to the extent that it considers appropriate in the circumstances of the case.

3. If such appointing authority has not issued a schedule of fees for arbitrators in international cases, any party may at any time request the appointing authority to furnish a statement setting forth the basis for establishing fees which is customarily followed in international cases in which the authority appoints arbitrators. If the appointing authority consents to provide such a statement, the arbitral tribunal in fixing its fees shall take such information into account to the extent that it considers appropriate in the circumstances of the case.

4. In cases referred to in paragraphs 2 and 3, when a party so requests and the appointing authority consents to perform the function, the arbitral tribunal shall fix its fees only after consultation with the appointing authority which may make any comment it deems appropriate to the arbitral tribunal concerning the fees.
