78. All statements, documents or other information supplied to, or applications made to, the Arbitral Tribunal by one Party will be communicated to the other Party, and any expert report or evidentiary document on which the Arbitral Tribunal may rely in making its decision must be communicated to the Parties. 79. Unless ordered by the Arbitral Tribunal, all hearings and meetings in arbitral proceedings, other than meetings of the Arbitral Tribunal, are open to the public. 80. The Arbitral Tribunal must schedule hearings to be held on consecutive days until completion. 81. All oral evidence must be taken in the presence of the Arbitral Tribunal and all the Parties unless a Party is absent by default or has waived the right to be present. 82. The Arbitral Tribunal may order any individual to be examined by the Arbitral Tribunal under oath or on affirmation in relation to the Disagreement and to produce before the Arbitral Tribunal all relevant documents within the individual's care, custody or control. 83. The document assemblies delivered under Section 74 will be deemed to have been entered into evidence at the hearing without further proof and without being read out at the hearing, but a Party may challenge the admissibility of any document so introduced. 84. If the Arbitral Tribunal considers it just and reasonable to do so, the Arbitral Tribunal may permit a document that was not previously listed under Section 67, or produced as required under Section 70 or 74, to be introduced at the hearing, but the Arbitral Tribunal may take that failure into account when fixing the costs to be awarded in the arbitration. 85. If the Arbitral Tribunal permits the evidence of a witness to be presented as a written statement, the other Party may require that witness to be made available for cross examination at the hearing. 86. The Arbitral Tribunal may order a witness to appear and give evidence, and, in that event, the Parties may cross examine that witness and call evidence in rebuttal. Default of a Party 87. If, without showing sufficient cause, the Applicant fails to communicate its statement of claim in accordance with Section 65, the Arbitral Tribunal may terminate the proceedings. 88. If, without showing sufficient cause, a respondent fails to communicate its statement of defence in accordance with Section 66, the Arbitral Tribunal must continue the proceedings without treating that failure in itself as an admission of the Applicant's allegations. 89. If, without showing sufficient cause, a Party fails to appear at the hearing or to produce documentary evidence, the Arbitral Tribunal may continue the proceedings and make the Arbitral Award on the evidence before it. 90. Before terminating the proceedings under Section 87, the Arbitral Tribunal must give all respondents written notice providing an opportunity to file a statement of claim in respect of the Disagreement within a specified period of time. 196
