The European Court of Justice (ECJ), officially just the Court of Justice (French: Cour de Justice), is the highest court in the European Union in matters of European Union law. As a part of the Court of Justice of the European Union it is tasked with interpreting EU law and ensuring its equal application across all EU member states. The Court was established in 1952 and is based in Luxembourg. It is composed of one judge per member state – currently 28 – although it normally hears cases in panels of three, five or 15 judges. The court has been led by president Koen Lenaerts since 2015.

The court was established in 1952, by the Treaty of Paris (1951) as part of the European Coal and Steel Community. It was established with seven judges, allowing both representation of each of the six member States and being an unequal number of judges in case of a tie. One judge was appointed from each member state and the seventh seat rotated between the "large Member States" (West Germany, France and Italy). It became an institution of two additional Communities in 1957 when the European Economic Community (EEC), and the European Atomic Energy Community (Euratom) were created, sharing the same courts with the European Coal and Steel Community.

The Maastricht Treaty was ratified in 1993, and created the European Union. The name of the Court did not change unlike the other institutions. The power of the Court resided in the Community pillar (the first pillar).

The Court gained power in 1997 with the signing of the Amsterdam Treaty. Issues from the third pillar were transferred to the first pillar. Previously, these issues were settled between the member states.
