Notes
(a) Reservation by the European Union pursuant to Article 3(l)(a) of the United Nations Convention on Transparency in Treaty-based Investor-State Arbitration (10 December 2014) (‘the Convention’): Pursuant to Article 3(l)(a) of the Convention, the European Union declares that it shall not apply the Convention when acting as a respondent in the case of a dispute under the Energy Charter Treaty, including as a result of the application of Article 47(3) of the Energy Charter Treaty, initiated against a Member State of the European Union which is not a party to the Convention, unless agreed upon otherwise with that Member State. The Energy Charter Treaty is a multilateral agreement. This reservation shall apply in respect to all parties to the Energy Charter Treaty that are parties to the Convention, including parties and former parties to the Energy Charter Treaty that made, have made and will make a notification pursuant to Article 47 of the Energy Charter Treaty.
