SIAC Arbitration Rules (2025)
19.1 Unless otherwise agreed by the parties, the Tribunal shall comprise one or three arbitrators. In the event that the parties have not agreed on the number of arbitrators, a sole arbitrator shall be appointed unless the Registrar determines, after considering the views of the parties, that the dispute warrants the appointment of three arbitrators.
19.2 If the parties have agreed that an arbitrator is to be appointed by any or all of the parties, the arbitrators already appointed, or any third person, body or organisation, that agreement shall be deemed an agreement to nominate an arbitrator under these Rules and shall be subject to appointment by the President in accordance with Rule 19.4.
19.3 The President may appoint any arbitrator whose appointment has been suggested or proposed by any or all of the parties, the arbitrators already appointed, or any third person, body or organisation.
19.4 In all cases, any arbitrator nominated by any or all of the parties, the arbitrators already appointed, or any third person, body or organisation, shall be subject to appointment by the President. The President may, after considering the views of the parties, the arbitrators already appointed, or the relevant third person, body or organisation, refuse to appoint any arbitrator under this Rule 19.4.
19.5 In appointing an arbitrator under these Rules, the President shall take into account any agreed qualifications and such considerations that are relevant to the impartiality or independence of the arbitrator.
19.6 The President shall consider whether the arbitrator has sufficient availability to conduct the arbitration in a prompt and efficient manner appropriate to the nature of the dispute.
19.7 Where the parties are of different nationalities, the President shall appoint a sole arbitrator or a presiding arbitrator of a different nationality than the parties, unless the parties have otherwise agreed or the President determines it to be appropriate otherwise, taking into account any proposals by the parties and the circumstances of the case.
19.8 The Registrar may, after considering the views of the parties, extend any timelines for appointment prescribed under these Rules or otherwise agreed by the parties.
19.9 If, under the terms of an appointment procedure agreed by the parties, the appointment cannot be effected on those terms, the President shall appoint the arbitrator(s).
19.10 If, under the terms of an appointment procedure agreed by the parties, there is a substantial risk of unequal treatment that may risk affecting the validity or enforceability of the award, the President may, after considering the views of the parties, take any necessary measure to constitute an independent and impartial Tribunal. In such case, each party shall be deemed to have waived any right to nominate an arbitrator or otherwise participate in the constitution of the Tribunal, and the President may revoke the appointment of any arbitrators.
19.11 The terms of appointment of each arbitrator shall be fixed by the
Registrar in accordance with these Rules and the Practice Notes for the time being in force. Prior to the constitution of the Tribunal, the parties may agree to alternative methods of determining the Tribunal’s fees. No change to the method of determining the Tribunal’s fees will be allowed after the constitution of the Tribunal.
19.12 The Tribunal shall be deemed to be constituted on the date so notified by the SIAC Secretariat to the parties.
19.13 Any decision by the President or the Registrar on appointment shall be final and not subject to appeal.
