Submission of Written Statements and Documents
Unless the parties have agreed otherwise under Article 14.1 or the Arbitral Tribunal should determine differently, the written stage of the proceedings shall be as set out below.
Within 30 days of receipt of written notification from the Registrar of the formation of the Arbitral Tribunal, the Claimant shall send to the Registrar a Statement of Case setting out in sufficient detail the facts and any contentions of law on which it relies, together with the relief claimed against all other parties, save and insofar as such matters have not been set out in its Request.
Within 30 days of receipt of the Statement of Case or written notice from the Claimant that it elects to treat the Request as its Statement of Case, the Respondent shall send to the Registrar a Statement of Defence setting out in sufficient detail which of the facts and contentions of law in the Statement of Case or Request (as the case may be) it admits or denies, on what grounds and on what other facts and contentions of law it relies. Any counterclaims shall be submitted with the Statement of Defence in the same manner as claims are to be set out in the Statement of Case.
Within 30 days of receipt of the Statement of Defence, the Claimant shall send to the Registrar a Statement of Reply which, where there are any counterclaims, shall include a Defence to Counterclaim in the same manner as a defence is to be set out in the Statement of Defence.
If the Statement of Reply contains a Defence to Counterclaim, within 30 days of its receipt the Respondent shall send to the Registrar a Statement of Reply to Counterclaim.
All Statements referred to in this Article shall be accompanied by copies (or, if they are especially voluminous, lists) of all essential documents on which the party concerned relies and which have not previously been submitted by any party, and (where appropriate) by any relevant samples and exhibits.
As soon as practicable following receipt of the Statements specified in this Article, the Arbitral Tribunal shall proceed in such manner as has been agreed in writing by the parties or pursuant to its authority under these Rules.
If the Respondent fails to submit a Statement of Defence or the Claimant a Statement of Defence to Counterclaim, or if at any point any party fails to avail itself of the opportunity to present its case in the manner determined by Article 15.2 to 15.6 or directed by the Arbitral Tribunal, the Arbitral Tribunal may nevertheless proceed with the arbitration and make an award.
