Article 15
Replacement of Arbitrators after Constitution of the Tribunal
(1) After a Tribunal has been constituted and
proceedings have begun, its composition shall remain unchanged; provided, however, that if
an arbitrator should die, become incapacitated, resign or be disqualified, the resulting
vacancy shall be filled as provided in this Article and Article 18 of these Rules.
(2) An arbitrator who becomes incapacitated shall, as
soon as possible, notify the other members of the Tribunal, and the Secretary-General
thereof.
(3) An arbitrator may resign by submitting his
resignation to the other members of the Tribunal and the Secretary-General. If the
arbitrator was appointed by one of the parties, the Tribunal shall promptly consider the
reasons for his resignation and decide whether it consents thereto. The Tribunal shall
promptly notify the Secretary-General of its decision.
Article 16
Disqualification of Arbitrators
(1) A party may propose to a Tribunal the
disqualification of any of its members on account of any fact indicating a manifest lack
of the qualities required by Article 9 of these Rules, or on the ground that he was
ineligible for appointment to the Tribunal under Article 7 of these Rules.
(2) A party proposing the disqualification of an
arbitrator shall promptly, and in any event before the proceeding is declared closed, file
its proposal with the Secretary-General, stating its reasons therefor.
(3) The Secretary-General shall forthwith:
(a) transmit the proposal to the members of the Tribunal
and, if it relates to a sole arbitrator or to a majority of the members of the Tribunal,
to the Chairman; and
(b) notify the other party of the proposal.
(4) The arbitrator to whom the proposal relates may,
without delay, furnish explanations to the Tribunal or the Chairman, as the case may be.
(5) The decision on any proposal to disqualify an
arbitrator shall be taken by the other members of the Tribunal except that where those
members are equally divided, or in the case of a proposal to disqualify a sole arbitrator,
or a majority of the arbitrators, the Chairman shall take that decision.
(6) Whenever the Chairman has to decide on a proposal to
disqualify an arbitrator, he shall take that decision within 30 days after he has received
the proposal.
(7) The proceeding shall be suspended until a decision
has been taken on the proposal.
