Section III. Arbitral proceedings

General Provisions

Article 15
1.  Subject to these rules, the arbitral tribunal may conduct the arbitration in such manner as it considers appropriate, provided that the parties are treated with equality and that at any stage of the proceedings each party is given a full opportunity of presenting his case.
 The arbitral tribunal may request the Centre to prepare with the parties a draft of terms of reference including all the necessary details for its consideration. It may also conduct a preliminary meeting for signing the terms of reference and to organize and schedule the subsequent proceedings with a view of expediting the resolution of the dispute.
2. If either party so requests at any stage of the proceedings, the arbitral tribunal shall hold hearings for the presentation of evidence by witnesses, including expert witnesses, or for oral argument. In the absence of such a request, the arbitral tribunal shall decide whether to hold such hearings or whether the proceedings shall be conducted on the basis of documents and other materials.
3. All documents or information supplied to the arbitral tribunal by one party shall at the same time be communicated by that party to the other party.
