Experts to the Arbitral Tribunal
Unless otherwise agreed by the parties in writing, the Arbitral Tribunal:
may appoint one or more experts to report to the Arbitral Tribunal on specific issues, who shall be and remain impartial and independent of the parties throughout the arbitration proceedings; and
may require a party to give any such expert any relevant information or to provide access to any relevant documents, goods, samples, property or site for inspection by the expert.
Unless otherwise agreed by the parties in writing, if a party so requests or if the Arbitral Tribunal considers it necessary, the expert shall, after delivery of his written or oral report to the Arbitral Tribunal and the parties, participate in one or more hearings at which the parties shall have the opportunity to question the expert on his report and to present expert witnesses in order to testify on the points at issue.
The fees and expenses of any expert appointed by the Arbitral Tribunal under this Article shall be paid out of the deposits payable by the parties under Article 24 and shall form part of the costs of the arbitration.
