SIAC Arbitration Rules (2025)
10.1 A party may be self-represented or represented or assisted by any person of its choice, including legal counsel, advocates, agents, or any other authorised representatives, subject to any applicable law.
10.2 Prior to the constitution of the Tribunal, the Registrar may direct any party representative to provide proof of authority in a form to be determined by the Registrar. Any question as to the validity of this proof of authority shall ultimately be determined by the Tribunal.
10.3 Prior to the constitution of the Tribunal, any change or addition by a party to its representatives must be communicated to the Registrar and the other parties.
10.4 After the constitution of the Tribunal, the Tribunal may direct any party representative to provide proof of authority in a form to be determined by the Tribunal.
10.5 After the constitution of the Tribunal, any change by a party to its representatives must be first proposed to the Tribunal. The Tribunal may, after considering the views of the parties, allow the proposed change of representatives. The Tribunal may withhold approval of any proposed change to a party’s representatives where such change could compromise the composition of the Tribunal or the integrity of the proceedings. In considering such a proposal, the Tribunal shall take into account, inter alia, the general principle that a party may be represented by a representative of its choice, the stage which the arbitration has reached, and the efficiency likely to result from maintaining the composition of the Tribunal.
