Art. 1 IBA Rules
Article 1. Scope of Application
1. Whenever the Parties have agreed or the Arbitral Tribunal has determined to apply the IBA Rules of Evidence, the Rules shall govern the taking of evidence, except to the extent that any specific provision of them may be found to be in conflict with any mandatory provision of law determined to be applicable to the case by the Parties or by the Arbitral Tribunal.
2. Where the Parties have agreed to apply the IBA Rules of Evidence, in whole or in part, they shall be deemed to have agreed, in the absence of a contrary indication, to the version as current on the date of such agreement.
3. In case of conflict between any provisions of the IBA Rules of Evidence and the General Rules, the Arbitral Tribunal shall apply the IBA Rules of Evidence in the manner that it determines best in order to accomplish, to the extent possible, the purposes of both the General Rules and the IBA Rules of Evidence, unless the Parties agree to the contrary.
4. In the event of any dispute regarding the meaning of the IBA Rules of Evidence, the Arbitral Tribunal shall interpret them according to their purpose and in the manner most appropriate for the particular arbitration.
5. Insofar as the IBA Rules of Evidence and the General Rules are silent on any matter concerning the taking of evidence and the Parties have not agreed otherwise, the Arbitral Tribunal shall conduct the taking of evidence as it deems appropriate, in accordance with the general principles of the IBA Rules of Evidence.
