5 URGENT INTERIM OR CONSERVATORY MEASURES

5.1 Urgent Interim or Conservatory Measures before the Arbitration Tribunal has been constituted. If before the Arbitration Tribunal has been constituted a party deems urgent interim or conservatory measures necessary to prevent imminent harm or irreparable injury, the party shall submit a motion to this effect to the President of the Arbitration Chamber, who shall appoint a permanent member of the Arbitration Chamber to act as emergency arbitrator. The role of the emergency arbitrator is to take a decision regarding the motion for urgent interim or conservatory measures, which if granted shall remain in force until the Arbitration Tribunal decides upon the merits (“Emergency Arbitrator”).

5.1.1 The Emergency Arbitrator shall decide on the motion for urgent interim or conservatory measures after hearing the opposing party, who shall be summonsed to contest the motion within forty-eight (48) hours. Urgent interim or conservatory measures may be granted without hearing the opposing party if this is indispensable on grounds of efficacy, in which case the arbitrator shall have the party concerned notified of this decision immediately.

5.1.2 The Emergency Arbitrator shall be paid a specific fee established by the President of the Arbitration Chamber in accordance with the Schedule of Filing & Arbitrator Fees and settled in advance by the party that moves for urgent interim or conservatory measures. The Emergency Arbitrator shall not participate in the Arbitration Tribunal that issues the final award or in any other that involves a related dispute.

5.1.3 The Emergency Arbitrator can only be appointed in case the arbitration clause contains specific provision authorizing his participation. Otherwise, the party shall apply to a court of law for urgent interim or conservatory measures to prevent irreparable injury or threatened wrong. Such application shall not be deemed renunciation of arbitration.

5.1.4 Any decision taken by an Emergency Arbitrator or court of law may be upheld or modified by the Arbitration Tribunal when constituted.

5.2 Urgent interim or conservatory measures after the Arbitration Tribunal has been constituted. fter the Arbitration Tribunal is constituted and before an award is made, the parties may at any time submit a motion for urgent interim or conservatory measures to protect property or rights against imminent harm or threatened wrong.

6 JOINDER OF PARTIES AND CONSOLIDATION OF PROCEEDINGS

6.1 Joinder of parties. Before any arbitrators have been appointed, the parties may request the inclusion of one or more additional parties in the arbitration proceedings by filing a Motion for Joinder of Parties (“Motion for Joinder”). Third parties with a legitimate claim to join or intervene in the proceedings may request permission to do so by filing a Motion for Joinder.

6.1.3 The parties shall be directed to respond to the Answers to Motions for Joinder within ten (10) days.

Should any party object and if the President of the Arbitration Chamber overrides such objection, enforcing the Motion for Joinder, the Arbitration Tribunal shall review the matter and issue a final decision regarding the joinder.

6.2 Consolidation of proceedings. When Requests for Arbitration involve issues of fact or law in common with arbitration proceedings that are already under way and are governed by these Rules, the President of the Arbitration Chamber may direct that the proceedings be consolidated after hearing the parties and taking into consideration the circumstances and progress already achieved in the proceedings in question.

6.2.1 Consolidation of proceedings is possible only in evidence production stage of the arbitration proceeding.

6.2.2 If Arbitration Tribunals have not been set up in any of the proceedings to be consolidated, and if the parties fail to reach a consensus on the composition of the Arbitration Tribunal for the consolidated proceedings, all arbitrators shall be appointed by the President of the Arbitration Chamber.

6.2.3 If an Arbitration Tribunal has been set up in any of the proceedings to be consolidated, it shall be competent to judge all the consolidated proceedings. Because the parties to other arbitration proceedings relinquish the right to appoint arbitrators if they recognize the consolidation, the Secretary-General shall send them copies of the Terms of Reference signed by the arbitrators in the Arbitration Tribunal that has been set up. Consolidation shall be possible only if the parties to more recent proceedings agree to the composition of this Arbitration Tribunal.

6.2.4 Should the parties fail to challenge the arbitrators within five (5) days of being invited to do so, the evidence shall be heard and an award issued by the existing Arbitration Tribunal.

6.2.5 The challenges to which 6.2.4 above refers shall be judged as provided for in 3.12 above.
