(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.
(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.
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 enquiries there as it may deem appropriate.
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.
(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.
Except as the parties otherwise agree, the Tribunal shall, if requested by a party, determine any incidental or additional claims or counter-claims 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.
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.
