SIAC Arbitration Rules (2025)
40.1 Prior to any hearing, the Tribunal may direct the parties to give notice of the identity of witnesses, including expert witnesses, whom the parties intend to produce, the subject matter of their testimony, and its relevance to the issues.
40.2 The Tribunal shall have the power to order or refuse to allow the appearance of witnesses to give oral evidence at any hearing or to limit oral witness testimony at any hearing.
40.3 Any witness who gives oral evidence may be questioned by each of the parties and their representatives and the Tribunal in such manner as the Tribunal may determine.
40.4 The Tribunal may direct the testimony of witnesses to be presented in written form, either as signed or sworn statements or any other form of recording. Subject to Rule 40.2, any party may request that such a witness attend a hearing for oral examination, whether in-person, by videoconference, teleconference, or any other form of electronic communication. If the witness fails to attend for oral examination, the Tribunal may determine the weight to be placed on such written testimony, disregard such written testimony, or exclude such written testimony altogether.
40.5 Subject to any applicable laws or regulations, in respect of any witness or potential witness whose evidence it intends to adduce, a party or its representatives:
(a) may interview any such witness or potential witness;
(b) assist such witness or potential witness in the preparation of a witness statement or expert report; and
(c) meet such witness prior to his or her appearance to give oral evidence at any hearing.
A party and its representatives should seek to ensure that the evidence of fact witnesses reflects their own account of the relevant facts and the evidence of experts reflects their genuinely held opinions.
