Request for Arbitration

Article 36

(1) Any Contracting State or any national of a Contracting State wishing to institute arbitration proceedings shall address a request to that effect in writing to the Secretary-General who shall send a copy of the request to the other party.

(2) The request shall contain information concerning the issues in dispute, the identity of the parties and their consent to arbitration in accordance with the rules of procedure for the institution of conciliation and arbitration proceedings.

(3) The Secretary-General shall register the request unless he finds, on the basis of the information contained in the request, that the dispute is manifestly outside the jurisdiction of the Centre. He shall forthwith notify the parties of registration or refusal to register.

Section 2
Constitution of the Tribunal

Article 37

(1) The Arbitral Tribunal (hereinafter called the Tribunal) shall be constituted as soon as possible after registration of a request pursuant to Article 36.

Article 38

If the Tribunal shall not have been constituted within 90 days after notice of registration of the request has been dispatched by the Secretary-General in accordance with paragraph (3) of Article 36, or such other period as the parties may agree, the Chairman shall, at the request of either party and after consulting both parties as far as possible, appoint the arbitrator or arbitrators not yet appointed. Arbitrators appointed by the Chairman pursuant to this Article shall not be nationals of the Contracting State party to the dispute or of the Contracting State whose national is a party to the dispute.

Article 39

The majority of the arbitrators shall be nationals of States other than the Contracting State party to the dispute and the Contracting State whose national is a party to the dispute; provided, however, that the foregoing provisions of this Article shall not apply if the sole arbitrator or each individual member of the Tribunal has been appointed by agreement of the parties.

Article 40

(1) Arbitrators may be appointed from outside the Panel of Arbitrators, except in the case of appointments by the Chairman pursuant to Article 38.

Powers and Functions of the Tribunal

Article 41

(1) The Tribunal shall be the judge of its own competence.

(2) Any objection by a party to the dispute that that dispute is not within the jurisdiction of the Centre, or for other reasons is not within the competence of the Tribunal, shall be considered by the Tribunal which shall determine whether to deal with it as a preliminary question or to join it to the merits of the dispute.

Article 42

(1) The Tribunal shall decide a dispute in accordance with such rules of law as may be agreed by the parties. In the absence of such agreement, the Tribunal shall apply the law of the Contracting State party to the dispute (including its rules on the conflict of laws) and such rules of international law as may be applicable.

(2) The Tribunal may not bring in a finding of non liquet on the ground of silence or obscurity of the law.

(3) The provisions of paragraphs (1) and (2) shall not prejudice the power of the Tribunal to decide a dispute ex aequo et bono if the parties so agree.

Article 43

Except as the parties otherwise agree, the Tribunal may, if it deems it necessary at any stage of the proceedings,

(a) call upon the parties to produce documents or other evidence, and

(b) visit the scene connected with the dispute, and conduct such inquiries there as it may deem appropriate.

Article 44

Any arbitration proceeding shall be conducted in accordance with the provisions of this Section and, except as the parties otherwise agree, in accordance with the Arbitration Rules in effect on the date on which the parties consented to arbitration. If any question of procedure arises which is not covered by this Section or the Arbitration Rules or any rules agreed by the parties, the Tribunal shall decide the question.

Article 45

(1) Failure of a party to appear or to present his case shall not be deemed an admission of the other party's assertions.

(2) If a party fails to appear or to present his case at any stage of the proceedings the other party may request the Tribunal to deal with the questions submitted to it and to render an award. Before rendering an award, the Tribunal shall notify, and grant a period of grace to, the party failing to appear or to present its case, unless it is satisfied that that party does not intend to do so.

Article 46

Except as the parties otherwise agree, the Tribunal shall, if requested by a party, determine any incidental or additional claims or counterclaims arising directly out of the subject-matter of the dispute provided that they are within the scope of the consent of the parties and are otherwise within the jurisdiction of the Centre.

Article 47

Except as the parties otherwise agree, the Tribunal may, if it considers that the circumstances so require, recommend any provisional measures which should be taken to preserve the respective rights of either party.

Section 5
Interpretation, Revision and Annulment of the Award

Article 50

(1) If any dispute shall arise between the parties as to the meaning or scope of an award, either party may request interpretation of the award by an application in writing addressed to the Secretary-General.

(2) The request shall, if possible, be submitted to the Tribunal which rendered the award. If this shall not be possible, a new Tribunal shall be constituted in accordance with Section 2 of this Chapter. The Tribunal may, if it considers that the circumstances so require, stay enforcement of the award pending its decision.

Article 51

(1) Either party may request revision of the award by an application in writing addressed to the Secretary-General on the ground of discovery of some fact of such a nature as decisively to affect the award, provided that when the award was rendered that fact was unknown to the Tribunal and to the applicant and that the applicant's ignorance of that fact was not due to negligence.

(2) The application shall be made within 90 days after the discovery of such fact and in any event within three years after the date on which the award was rendered.

(3) The request shall, if possible, be submitted to the Tribunal which rendered the award. If this shall not be possible, a new Tribunal shall be constituted in accordance with Section 2 of this Chapter.

(4) The Tribunal may, if it considers that the circumstances so require, stay enforcement of the award pending its decision. If the applicant requests a stay of enforcement of the award in his application, enforcement shall be stayed provisionally until the Tribunal rules on such request.

Article 52

(1) Either party may request annulment of the award by an application in writing addressed to the Secretary-General on one or more of the following grounds:

(a) that the Tribunal was not properly constituted;

(b) that the Tribunal has manifestly exceeded its powers;

(c) that there was corruption on the part of a member of
the Tribunal;

(d) that there has been a serious departure from a fundamental rule of procedure; or

(e) that the award has failed to state the reasons on which it
is based.

(2) The application shall be made within 120 days after the date on which the award was rendered except that when annulment is requested on the ground of corruption such application shall be made within 120 days after discovery of the corruption and in any event within three years after the date on which the award was rendered.

(3) On receipt of the request the Chairman shall forthwith appoint from the Panel of Arbitrators an ad hoc Committee of three persons. None of the members of the Committee shall have been a member of the Tribunal which rendered the award, shall be of the same nationality as any such member, shall be a national of the State party to the dispute or of the State whose national is a party to the dispute, shall have been designated to the Panel of Arbitrators by either of those States, or shall have acted as a conciliator in the same dispute. The Committee shall have the authority to annul the award or any part thereof on any of the grounds set forth in paragraph (1).

(4) The provisions of Articles 41-45, 48, 49, 53 and 54, and of Chapters VI and VII shall apply mutatis mutandis to proceedings before the Committee.

(5) The Committee may, if it considers that the circumstances so require, stay enforcement of the award pending its decision. If the applicant requests a stay of enforcement of the award in his application, enforcement shall be stayed provisionally until the Committee rules on such request.

(6) If the award is annulled the dispute shall, at the request of either party, be submitted to a new Tribunal constituted in accordance with Section 2 of this Chapter.

Section 6
Recognition and Enforcement of the Award

Article 53

(1) The award shall be binding on the parties and shall not be subject to any appeal or to any other remedy except those provided for in this Convention. Each party shall abide by and comply with the terms of the award except to the extent that enforcement shall have been stayed pursuant to the relevant provisions of this Convention.

(2) For the purposes of this Section, "award" shall include any decision interpreting, revising or annulling such award pursuant to Articles 50, 51 or 52.

Article 54

(1) Each Contracting State shall recognize an award rendered pursuant to this Convention as binding and enforce the pecuniary obligations imposed by that award within its territories as if it were a final judgment of a court in that State. A Contracting State with a federal constitution may enforce such an award in or through its federal courts and may provide that such courts shall treat the award as if it were a final judgment of the courts of a constituent state.

(2) A party seeking recognition or enforcement in the territories of a Contracting State shall furnish to a competent court or other authority which such State shall have designated for this purpose a copy of the award certified by the Secretary-General. Each Contracting State shall notify the Secretary-General of the designation of the competent court or other authority for this purpose and of any subsequent change in such designation.

(3) Execution of the award shall be governed by the laws concerning the execution of judgments in force in the State in whose territories such execution is sought.

Article 55

Nothing in Article 54 shall be construed as derogating from the law in force in any Contracting State relating to immunity of that State or of any foreign State from execution.
