1) Where the parties have agreed to submit to arbitration under the Rules, they shall be deemed to have submitted ipso facto to the Rules in effect on the date of commencement of the arbitration, unless they have agreed to submit to the Rules in effect on the date of their arbitration agreement.
2) By agreeing to arbitration under the Rules, the parties have accepted that the arbitration shall be administered by the Court.
3) If any party against which a claim has been made does not submit an Answer, or if any party raises one or more pleas concerning the existence, validity or scope of the arbitration agreement or concerning whether all of the claims made in the arbitration may be determined together in a single arbitration, the arbitration shall proceed and any question of jurisdiction or of whether the claims may be determined together in that arbitration shall be decided directly by the arbitral tribunal, unless the Secretary General refers the matter to the Court for its decision pursuant to Article 6(4).
4) In all cases referred to the Court under Article 6(3), the Court shall decide whether and to what extent the arbitration shall proceed. The arbitration shall proceed if and to the extent that the Court is prima facie satisfied that an arbitration agreement under the Rules may exist. In particular:
(i) where there are more than two parties to the arbitration, the arbitration shall proceed between those of the parties, including any additional parties joined pursuant to Article 7(1), with respect to which the Court is prima facie satisfied that an arbitration agreement under the Rules that binds them all may exist; and
(ii) where claims pursuant to Article 9 are made under more than one arbitration agreement, the arbitration shall proceed as to those claims with respect to which the Court is prima facie satisfied (a) that the arbitration agreements under which those claims are made may be compatible, and (b) that all parties to the arbitration may have agreed that those claims can be determined together in a single arbitration.
The Court’s decision pursuant to Article 6(4) is without prejudice to the admissibility or merits of any party’s plea or pleas.
5)In all matters decided by the Court under Article 6(4), any decision as to the jurisdiction of the arbitral tribunal, except as to parties or claims with respect to which the Court decides that the arbitration cannot proceed, shall then be taken by the arbitral tribunal itself.
6)Where the parties are notified of the Court’s decision pursuant to Article 6(4) that the arbitration cannot proceed in respect of some or all of them, any party retains the right to ask any court having jurisdiction whether or not, and in respect of which of them, there is a binding arbitration agreement.
7)Where the Court has decided pursuant to Article 6(4) that the arbitration cannot proceed in respect of any of the claims, such decision shall not prevent a party from reintroducing the same claim at a later date in other proceedings.
8) If any of the parties refuses or fails to take part in the arbitration or any stage thereof, the arbitration shall proceed notwithstanding such refusal or failure.
9)Unless otherwise agreed, the arbitral tribunal shall not cease to have jurisdiction by reason of any allegation that the contract is non-existent or null and void, provided that the arbitral tribunal upholds the validity of the arbitration agreement. The arbitral tribunal shall continue to have jurisdiction to determine the parties’ respective rights and to decide their claims and pleas even though the contract itself may be non-existent or null and void.

2. Any party making a claim pursuant to Article 8(1) shall provide the information specified in Article 4(3) subparagraphs c), d), e) and f).

Article 23 – Terms of Reference
1) As soon as it has received the file from the Secretariat, the arbitral tribunal shall draw up, on the basis of documents or in the presence of the parties and in the light of their most recent submissions, a document defining its Terms of Reference. This document shall include the following particulars:
a) the names in full, description, address and other contact details of each of the parties and of any person(s) representing a party in the arbitration;
b) the addresses to which notifications and communications arising in the course of the arbitration may be made;
c) a summary of the parties’ respective claims and of the relief sought by each party, together with the amounts of any quantified claims and, to the extent possible, an estimate of the monetary value of any other claims;
d) unless the arbitral tribunal considers it inappropriate, a list of issues to be determined;
e) the names in full, address and other contact details of each of the arbitrators;
f) the place of the arbitration; and
g) particulars of the applicable procedural rules and, if such is the case, reference to the power conferred upon the arbitral tribunal to act as amiable compositeur or to decide ex aequo et bono.
2) The Terms of Reference shall be signed by the parties and the arbitral tribunal. Within 30 days from the date on which the file has been transmitted to it, the arbitral tribunal shall transmit to the Court the Terms of Reference signed by it and by the parties. The Court may extend this time limit pursuant to a reasoned request from the arbitral tribunal or on its own initiative if it decides it is necessary to do so.
3) If any of the parties refuses to take part in the drawing up of the Terms of Reference or to sign the same, they shall be submitted to the Court for approval. When the Terms of Reference have been signed in accordance with Article 23(2) or approved by the Court, the arbitration shall proceed.
4) After the Terms of Reference have been signed or approved by the Court, no party shall make new claims which fall outside the limits of the Terms of Reference unless it has been authorized to do so by the arbitral tribunal, which shall consider the nature of such new claims, the stage of the arbitration and other relevant circumstances.
