UNCITRAL Arbitration Rules
The UNCITRAL Arbitration Rules were adopted in 1976 after extensive deliberations and consultations with various interested international organizations and leading arbitration experts. The General Assembly of the United Nations has recommended the use of the UNCITRAL Arbitration Rules in international commercial contracts. Revised UNCITRAL Arbitration Rules were adopted in 2010 and are intended to reflect the evolution in arbitral practice in the period since the adoption of the 1976 Rules.
The 2010 Rules are presumed to apply to arbitration agreements concluded after August 15, 2010, subject to the provisions of Article 1(2) of the 2010 Rules.
In order for these rules to function most efficiently, parties should specify an appointing authority in their arbitration agreement who will appoint arbitrators and decide challenges when necessary. If parties fail to designate an appointing authority in their arbitration agreement, or the designated appointing authority refuses or fails to act, both the 1976 and 2010 UNCITRAL Arbitration Rules provide that any party may request the Secretary-General of the PCA to make such designation. Under either the 1976 or 2010 Rules, the Secretary-General of the PCA may also serve directly as appointing authority if the parties so agree.
In 2013 a new paragraph was added to the 2010 Rules to incorporate the new UNCITRAL Rules on Transparency in Treaty-based Investor-State Arbitration. The Rules on Transparency will apply to treaty-based investor-state arbitration initiated under the UNCITRAL Arbitration Rules in respect of treaties concluded on or after 1 April 2014 unless the Parties to the relevant treaty have agreed otherwise. They will also apply in respect of investment treaties concluded before 1 April 2014 if the parties to the arbitration or the Parties to the relevant investment treaty have agreed to their application after 1 April 2014. In respect of multilateral investment treaties concluded before 1 April 2014, the Rules on Transparency will apply if the State of the claimant and the respondent State have agreed to their application.
In addition, the Rules on Transparency may be used in ad hoc proceedings or investor-state arbitrations instituted under rules other than the UNCITRAL Arbitration Rules.
