Chapter III
The Tribunal
Article 6
General Provisions
(1) In the absence of agreement between the parties regarding the number
of arbitrators and the method of their appointment, the Tribunal shall
consist of three arbitrators, one arbitrator appointed by each party and
the third, who shall be the President of the Tribunal, appointed by agreement
of the parties, all in accordance with Article 9 of these Rules.
(2) Upon the dispatch of the notice of registration of the request for
arbitration, the parties shall promptly proceed to constitute a Tribunal.
(3) The Tribunal shall consist of a sole arbitrator or any uneven number
of arbitrators appointed as the parties shall agree.
(4) If the Tribunal shall not have been constituted within 90 days after
the notice of registration of the request for arbitration has been dispatched
by the Secretary-General, or such other period as the parties may agree,
the Chairman of the Administrative Council (hereinafter called the "Chairman")
shall, at the request in writing of either party transmitted through the
Secretary-General, appoint the arbitrator or arbitrators not yet appointed
and, unless the President shall already have been designated or is to
be designated later, designate an arbitrator to be President of the Tribunal.
(5) Except as the parties shall otherwise agree, no person who had previously
acted as a conciliator or arbitrator in any proceeding for the settlement
of the dispute or as a member of any fact-finding committee relating thereto
may be appointed as a member of the Tribunal.
Article 7
Nationality of Arbitrators
(1) The majority of the arbitrators shall be nationals of States other
than the State party to the dispute and of the State whose national is
a party to the dispute, unless the sole arbitrator or each individual
member of the Tribunal is appointed by agreement of the parties. Where
the Tribunal is to consist of three members, a national of either of these
States may not be appointed as an arbitrator by a party without the agreement
of the other party to the dispute. Where the Tribunal is to consist of
five or more members, nationals of either of these States may not be appointed
as arbitrators by a party if appointment by the other party of the same
number of arbitrators of either of these nationalities would result in
a majority of arbitrators of these nationalities.
(2) Arbitrators appointed by the Chairman shall not be nationals of the
State party to the dispute or of the State whose national is a party to
the dispute.
Article 8
Qualifications of Arbitrators
Arbitrators shall be persons of high moral character and recognized competence
in the fields of law, commerce, industry or finance, who may be relied
upon to exercise independent judgment.
Article 9
Method of Constituting the Tribunal in the Absence
of Agreement Between the Parties
(1) If the parties have not agreed upon the number of arbitrators and
the method of their appointment within 60 days after the registration
of the request, the Secretary-General shall, upon the request of either
party promptly inform the parties that the Tribunal is to be constituted
in accordance with the following procedure:
(a) either party shall, in a communication to the other party:
(i) name two persons, identifying one of them, who shall not have
the same nationality as nor be a national of either party, as the
arbitrator appointed by it, and the other as the arbitrator proposed
to be the President of the Tribunal; and
(ii) invite the other party to concur in the appointment of the arbitrator
proposed to be the President of the Tribunal and to appoint another
arbitrator;
(b) promptly upon receipt of this communication the other party shall,
in its reply:
(i) name a person as the arbitrator appointed by it, who shall not
have the same nationality as nor be a national of either party; and
(ii) concur in the appointment of the arbitrator proposed to be the
President of the Tribunal or name another person as the arbitrator
proposed to be President; and

the initiating party shall notify the other party whether it concurs
in the appointment of the arbitrator proposed by that party to be the
