The Court of Justice of the European Union, formerly known as the Court of Justice of the European Communities, is one of the seven principal EU institutions.
It includes the Court of Justice, the General Court and the Civil Service Tribunal.
Its role is to ensure that EU law is correctly applied and that there is uniformity regarding its interpretation across the Union.
To do this, it monitors and controls the legality of acts from EU institutions and imposes relevant treaty obligations on EU Member States.
National judges can also refer a matter to the Court for interpretation of a point of EU law.
