Uncitral Rules on Transparency in Treaty-Based Investor-State Arbitration

Abstract

On July 11, 2013, the United Nations Commission on International Trade Law (UNCITRAL) adopted the UNCITRAL Rules on Transparency in Treaty-based Investor-State Arbitration (Transparency Rules). The new Transparency Rules are the product of three years of negotiations in UNCITRAL. The Transparency Rules will be available in two forms: (1) as part of the UNCITRAL Arbitration Rules, for use in arbitrations conducted under those rules, and (2) as a free-standing set of rules, available for use in arbitrations conducted under other arbitral rules, such as the Rules of the International Centre for Settlement of Investment Disputes (ICSID), or in ad hoc proceedings. The Transparency Rules, as well as the new version of the UNCITRAL Arbitration Rules that incorporates the Transparency Rules, will come into effect on April 1, 2014. The Transparency Rules are for use only in treaty-based investor-State arbitration – not in traditional commercial arbitration.
