IBA Rules on the Taking of Evidence in International Arbitration: The rules

• 1 These IBA Rules on the Taking of Evidence in International Arbitration are intended to provide an efficient, economical and fair process for the taking of evidence in international arbitrations, particularly those between Parties from different legal traditions. They are designed to supplement the legal provisions and the institutional, ad hoc or other rules that apply to the conduct of the arbitration.
• 2 Parties and Arbitral Tribunals may adopt the IBA Rules of Evidence, in whole or in part, to govern arbitration proceedings, or they may vary them or use them as guidelines in developing their own procedures. The Rules are not intended to limit the flexibility that is inherent in, and an advantage of, international arbitration, and Parties and Arbitral Tribunals are free to adapt them to the particular circumstances of each arbitration.
• 3 The taking of evidence shall be conducted on the principles that each Party shall act in good faith and be entitled to know, reasonably in advance of any Evidentiary Hearing or any fact or merits determination, the evidence on which the other Parties rely.
