Parliament gives its consent to the conclusion of the United Nations Convention on Transparency in Treaty-based Investor-State Arbitration, which increases public access to documents and hearings in investor-state disputes. The Convention applies UNCITRAL Transparency Rules to investment treaties concluded before 1 April 2014, requiring public documents, open hearings, and civil society submissions. Ratification is a first step toward broader reform, including a Multilateral Investment Court, and its method should be replicated in other forums.

Committee position. The Committee on International Trade recommends that Parliament give its consent to the conclusion of the agreement.

Key points

  1. Parliament consents to the conclusion of the agreement.
  2. The Convention marks a step towards greater public access to documents and hearings, and inclusion of civil society in investor-state disputes.
  3. Under common arbitration rules, disputes can remain hidden from public view; one party can demand secrecy even when cases target democratically decided measures and lead to billion-dollar awards.
  4. The Mauritius Convention facilitates application of UNCITRAL Transparency Rules to investment treaties concluded before 1 April 2014.
  5. The rules require all documents, including tribunal decisions and party submissions, to be made public; hearings open to the public; and interested parties allowed to make submissions.
  6. The Convention retroactively applies to investment treaties signed before the introduction of the transparency rules, without need for individual renegotiation.
  7. Approximately 1,200 agreements involving EU Member States fall under the Convention's scope; the Energy Charter Treaty is the only treaty covered at EU level.
  8. Ratification is a first step in broader reform for a Multilateral Investment Court; its method should be replicated, for instance in OECD work to align investment treaties with Paris Agreement climate goals.
