Investor-State Dispute Settlement

In 2013, UNCITRAL amended the Arbitration Rules to incorporate the UNCITRAL Rules on Transparency in Treaty-based Investor-State Arbitration, application of which is promoted by United Nations Convention on Transparency in Treaty-based Investor-State Arbitration (New York, 2014) or the Mauritius Convention on Transparency. In 2017, the Mauritius Convention on Transparency entered into force. The Convention provides an efficient mechanism to supplement existing investment treaties (concluded prior to April 2014) with respect to transparency related obligations.

At its fiftieth session in 2017, the Commission entrusted Working Group III with a broad mandate to work on the possible reform of investor-State dispute settlement (ISDS).  Instruments resulting from that work, as adopted by the Commission, are presented on this page.
