The United Nations Convention on Transparency in Treaty-based Investor-State Arbitration (New York, 2014) (the Mauritius Convention on Transparency) entered into force on 18 October.
The convention has to date been ratified by Canada, Mauritius and Switzerland. None of the ratifying states made reservations and, as a result, the UNCITRAL Rules on Transparency in Treaty-based Investor-State Arbitration are now part of the investor-state dispute settlement regime created by investment treaties concluded by those three states.
The Mauritius Convention on Transparency aims to provide states and regional economic integration organizations with an efficient mechanism that extends the scope of the transparency rules to investment treaties concluded before the transparency rules entered into force on 1 April 2014.
The convention is open for signature, ratification, and accession by states and regional economic integration organizations. Other than the three state parties, there are 19 signatories to the convention.
