If a possible infringement of EU law is identified by the Commission or reported in a complaint, the Commission attempts to quickly resolve the underlying problem with the Member State concerned by means of a structured dialogue (EU Pilot).
Member States can provide further factual or legal information on a potential case of violation of Union law – the goal being to find a quick solution in compliance with EU law and thus to avoid the need for formal infringement procedure.
If the Member State does not agree with the Commission or fails to implement a solution to rectify the suspected violation of EU law, the Commission may launch formal infringement procedure. These contain a number of steps foreseen by the Treaties, each of which is laid down in a formal decision:
|1. letter of formal notice||
|2. reasoned opinion||
|3. referral to Court of Justice||
|4. judgment by Court of Justice||
|5. case returned to Court of Justice||
