Each Member State is responsible for the implementation of EU Law within its own legal system. Non-compliance means failure by a Member State to fulfil its obligations under EU Law. An action for failure to fulfil obligations directed against a Member State which has failed to comply with its obligations under European Union law may be brought by the Commission or by another Member State. In the history of European integration only six times one Member State has directly brought infringement proceedings against another State. Of the six cases, only four proceeded to judgment. The European Institutions and the Member States should continue to develop their work to ensure that EU law is correctly applied and implemented.
