Adopted by UNCITRAL on 28 April 1976, the UNCITRAL Arbitration Rules provide a comprehensive set of procedural rules upon which parties may agree for the conduct of arbitral proceedings arising out of their commercial relationship and are widely used in ad hoc arbitrations as well as administered arbitrations. The Rules cover all aspects of the arbitral process, providing a model arbitration clause, setting out procedural rules regarding the appointment of arbitrators and the conduct of arbitral proceedings and establishing rules in relation to the form, effect and interpretation of the award.
