This is an Opinion Statement prepared by the CFE ECJ Task Force on Case C-172/13, European Commission v United Kingdom, which was decided by the Grand Chamber of the Court of Justice of the European Union (ECJ) on 3 February 2015. This case is in some ways a follow-up to the ECJ’s decision in Marks & Spencer and comments on whether the legislative amendments introduced by the United Kingdom are sufficient to ensure compliance with European Union law. After illustrating the case, arguments of the parties and decision of the Court, this Opinion Statement will focus on selected critical points from the Courts decision and Advocate General Kokott’s opinion.
