The Legal Service of the Council of the European Union issued its opinion, 1 March 2018, Directive 2009/73/EC of the European Parliament and of the Council of 13 July 2009 concerning common rules for the internal market in natural gas and repealing Directive 2003/55/EC – compatibility with UNCLOS, ST 6738 2018 INIT. The opinion states that:
“The Union does not have jurisdiction to apply energy law on unbundling, transparency, third-party access and regulated tariffs, which is unrelated to the economic exploitation of the EEZ, to pipelines crossing the EEZ of Member States. The application of the Gas Directive to the EEZ would be contrary to Articles 56 and 58 of UNCLOS as interpreted by the Court of Justice” (para. 21).
