The enforcement of EU law on non-compliant national authorities has, at its heart, infringement proceedings brought pursuant to Articles 258 to 260 TFEU. That focus is embedded in the scheme of the EU Treaties. In that regard, infringement proceedings are a particular feature of the EU legal order. As the Court of Justice stated in one of its first cases, ‘it is a procedure far exceeding the rules heretofore recognized in classical international law, to ensure that obligations of States are fulfilled’. Indeed, under the rules of public international law, there is no obligation to settle disputes or to establish formal and legal procedures for dispute resolution, which, where they exist, always depend on the consent of the parties concerned. By contrast, the jurisdiction of the Court in cases of EU law infringements by Member States is compulsory and constitutes a corollary to membership in the European Union.
