(a) the additional party shall not be joined after the appointment of the arbitral tribunal unless all parties to the arbitration and the additional party so agree in writing, and further agree that the additional party shall waive any right to participate in the selection of the arbitral tribunal that it would or might have had, had it been joined prior to the appointment of the arbitral tribunal;

(b) the arbitral tribunal shall, after consultation with the parties, determine in its sole discretion whether the additional party should be joined, taking into account the stage of the arbitration, whether joinder would serve the interests of justice and efficiency, and such other matters as it considers appropriate in the circumstances of the case; and

(c) the arbitral tribunal, if it permits joinder, shall determine the time, form and content of any Response to Request for Joinder.

28.5 If joined, the additional party shall be a party to the arbitration for all purposes.

Article 29: Consolidation

29.1 If two or more arbitrations subject to these Rules are commenced pursuant to the same arbitration agreement and between the same parties, the Chamber may, in its discretion and after consultation with the parties, consolidate the arbitrations into a single arbitration subject to these Rules, provided that no arbitral tribunal has yet been appointed in any of the arbitrations to be consolidated.

29.2 Following the appointment of the arbitral tribunal, the arbitral tribunal shall, on the application of any party, and having consulted all the parties, have the power to consolidate two or more arbitrations commenced under these Rules into a single arbitration, provided that no arbitral tribunal has been appointed in the other arbitration or arbitrations, or, if appointed, is the same arbitral tribunal as the arbitral tribunal appointed in the arbitration that commenced first; and

(a) all parties to the arbitrations to be consolidated have agreed in writing to consolidation; or

(b) all claims and counterclaims in the arbitrations are made under the same arbitration agreement; or

(c) if the claims and counterclaims in the arbitrations are made under more than one arbitration agreement, the arbitrations involve the same parties, the disputes in the arbitrations arise in connection with the same legal relationship and the arbitral tribunal determines that the arbitration agreements are compatible.

29.3 In determining whether to consolidate two or more arbitrations, the arbitral tribunal shall take into account the stage of the arbitrations, whether the consolidation of the arbitrations would serve the interests of justice and efficiency, and such other matters as it considers appropriate in the circumstances of the case.

29.4 When arbitrations are consolidated, they shall be consolidated into the arbitration that commenced first, unless otherwise agreed in writing by all parties or the arbitral tribunal determines otherwise.
