SIAC Arbitration Rules (2025)

33.1 Unless the Tribunal determines otherwise, after considering the views of the parties, the submission of written submissions shall proceed as set out in this Rule 33.
33.2 Unless already submitted pursuant to Rule 6.4, the Claimant shall, within a period of time to be determined by the Tribunal, deliver to the Respondent, the Tribunal, and the SIAC Secretariat, a Statement of Claim setting out:
(a) a statement of facts supporting the claim;
(b) the legal grounds or arguments supporting the claim; and
(c) the relief sought.
33.3 Unless already submitted pursuant to Rule 7.2, the Respondent shall, within a period of time to be determined by the Tribunal, deliver to the Claimant, the Tribunal, and the SIAC Secretariat, a Statement of Defence (and Statement of Counterclaim, if any) setting out:
(a) a statement of facts supporting the defence to the Statement of Claim and the Statement of Counterclaim (if any);
(b) the legal grounds or arguments supporting the defence, counterclaim, cross-claim, or set-off; and
(c) the relief sought.
33.4 If a Statement of Counterclaim is submitted, the Claimant shall, within a period of time to be determined by the Tribunal, deliver to the Respondent, the Tribunal, and the SIAC Secretariat, a Statement of Defence to Counterclaim setting out:
(a) a statement of facts supporting the Statement of Defence to Counterclaim;
(b) the legal grounds or arguments supporting the defence, crossclaim, or set-off; and
(c) the relief sought.
33.5 A party may amend its claim or defence, including a counterclaim, cross-claim, or set-off with leave of the Tribunal. The Tribunal shall grant such leave unless it considers it inappropriate to allow such amendment having regard to when it is requested or the prejudice to the other parties or any other circumstances. A claim or defence, including a counterclaim, cross-claim, or set-off, may not be amended in such a manner that the amended claim or defence, including a counterclaim, cross-claim, or set-off, falls outside the scope of the arbitration agreement.
33.6 The Tribunal may, after considering the views of the parties, decide which further written submissions are required from the parties or may be presented by them.
33.7 All submissions referred to in this Rule 33 shall be accompanied by copies of all supporting documents which have not previously been submitted by any party. The Tribunal may direct, after considering the views of the parties, that written submissions shall be accompanied by copies of supporting witness statements and expert reports.
