Bolivia (Plurinational State of) signs the United Nations Convention on Transparency in Treaty-based Investor-State Arbitration

VIENNA, 17 April (UN Information Service) - On 16 April 2018, Bolivia (Plurinational State of) signed the United Nations Convention on Transparency in Treaty-based Investor-State Arbitration ("The Mauritius Convention on Transparency").

The Convention entered into force on 18 October 2017 and has been ratified by Canada, Mauritius and Switzerland.

The Convention has further been signed by Australia, Belgium, Benin, Cameroon, Congo, Finland, France, Gabon, Germany, Iraq, Italy, Luxembourg, Madagascar, the Netherlands, Sweden, Syria, the United Kingdom and the United States.

The Convention is open for signature, ratification and accession by States and regional economic integration organizations. For up-to-date information on parties and signatories to the Convention, please see the UNCITRAL website.

The Mauritius Convention on Transparency aims to provide States and regional economic integration organizations with an efficient mechanism that extends the scope of the UNCITRAL Rules on Transparency in Treaty-based investor-State Arbitration ("Rules on Transparency") to investment treaties concluded before the Rules entered into force on 1 April 2014. The Rules on Transparency provide procedural rules that ensure transparency and public accessibility to treaty-based investor-State arbitration, the proceedings of which have traditionally been conducted behind closed doors. Together with the Rules on Transparency, the Mauritius Convention on Transparency takes into account both the public interest in such arbitrations and the interest of the parties to resolve disputes in a fair and efficient manner. It is expected that the Convention will significantly contribute to enhancing transparency in investor-State dispute resolutions.
