to the constitution of the Commission, Tribunal or Committee to the extent it exceeds the amount paid toward such expenses under Article 5 of these Rules; and

(ii) if at any time the Secretary-General determines that the advances made by the parties will not cover a revised estimate of expenses for the applicable period, he shall request the parties to make a supplementary advance payment.

(b) The Secretariat shall not be required to provide any service in connection with a proceeding or to pay the fees, allowances or expenses of the members of any Commission, Tribunal or Committee, unless sufficient advance payments shall previously have been made.

Article 12
Quarterly Statements

As soon as possible after the end of each calendar quarter the Secretariat shall ascertain the actual expenses incurred and commitments entered into by it with regard to each proceeding and shall appropriately charge or credit the parties, taking into account the advance payments made by them.

Article 13
Division of Charges

In connection with every conciliation, arbitration or fact-finding proceeding each party shall pay one-half of each payment requested by the Secretariat, without prejudice to the final decision on the payment of the cost of an arbitration proceeding to be made by the Tribunal pursuant to Article 59 of the Arbitration (Additional Facility) Rules. All amounts shall be payable at the place and in the currencies specified by the Secretariat, as soon as a request for payment is made by it. If the amounts requested are not paid in full within 30 days, then the Secretariat shall inform both parties of the default and give an opportunity to either of them to make the required payment. At any time 15 days after such information is sent, the Secretary-General may move that the Commission, Tribunal or Committee stay the proceeding, if by the date of such motion any part of the required payment is still outstanding. If any proceeding is stayed for non-payment for a consecutive period in excess of six months, the Secretary-General may, after notice to and as far as possible in consultation with the parties, move that the competent body discontinue the proceeding.

Article 14
Special Services to Parties

The Secretariat shall only perform any special service for a party in connection with a proceeding (for example, the provision of translations or copies) if the party shall in advance have deposited an amount sufficient to cover the charge for such service.
