Page contentsPage contents What is an infringement procedure? According to the EU treaties, the Commission may take legal action – an infringement procedure – against an EU Member State that implements EU law incompletely or incorrectly. The Commission may refer the issue to the Court of Justice, which can impose financial sanctions.The Commission identifies possible infringements of EU law on the basis of its own investigations, the communication of transposition measures submitted by Member States or following complaints from citizens, businesses or other stakeholders.You can find out more by visiting the dedicated section on Implementing EU law. The stages of an infringement procedure If a Member State fails to communicate measures transposing directives into their national legal order (e.g. adopting national laws fully implementing the content of a directive in the national legal order), or doesn’t rectify a violation of EU law (e.g. the breach/bad application of the EU Treaties, Regulations, Directives, Decisions etc.), the Commission may launch a formal infringement procedure. The procedure follows a number of steps laid out in the EU treaties, each ending with a formal decision: 1. Formal notice The Commission sends a letter of formal notice explaining the detected grievance to the Member State concerned, which must send a reply within a specified period, usually 2 months. Member States can provide further information and their arguments to reply to the Commission’s arguments.2. Reasoned opinionIf the Commission still concludes that the Member State is failing to fulfil its obligations under EU law, it may send a reasoned opinion. It explains why the Commission considers that the Member State is breaching EU law. Member States must reply within a specified period, usually 2 months.3. Referral to the Court of JusticeIf the Member State still doesn't comply or the explanations provided are deemed unsatisfactory, the Commission may decide to refer the matter to the Court of Justice. Most cases are settled before being referred to the court.4. Financial penaltiesIf the case concerns the failure by a Member State to communicate measures implementing the provisions of a directive, the Commission will ask the Court of Justice to impose financial penalties.5. Action to comply with the judgmentIf the court finds that a Member State has breached EU law, the national authorities must take action to comply with the Court of Justice judgment (and in the case in point 4, above, the court will impose financial penalties).6. Failure to rectify the situationIf, despite the court's judgment, the Member State still doesn't rectify the situation, the Commission may refer the Member State back to the Court of Justice.7. Second procedureThis second procedure begins by sending a letter of formal notice to the Member State concerned. If the Member State does not reply on time or the explanations are not satisfactory, the Commission may refer the case to the Court of Justice for a second time (there is no reasoned opinion stage).8. Second procedure financial penaltiesWhen referring a Member State to the Court of Justice for the second time, the Commission will request that the Court of Justice impose financial penalties, which will consist of a lump sum and/or a daily payment depending on the circumstances of the case. Annual report on monitoring the application of EU law The Commission also publishes an annual report reviewing key aspects of the application of EU law and presenting relevant implementation and enforcement actions by policy area and country.Annual reports on monitoring the application of EU law EU Home Affairs law infringement DG HOME is responsible for ensuring that Member States apply EU Home Affairs law correctly.
