The Court of Justice of the European Union (CJEU) (French: Cour de justice de l'Union européenne or "CJUE"; Latin: Curia[2]) is the judicial branch of the European Union (EU).

It has a sui generis court system, meaning 'of its own kind', and is a supranational institution.

[5] The CJEU is the chief judicial authority of the EU and oversees the uniform application and interpretation of European Union law, in co-operation with the national judiciary of the member states.

[6] The CJEU consists of two major courts:[7] Judges and advocate generals are appointed for a "renewable 6-year term, jointly by national governments".

[9] The CJEU's specific mission is to ensure that "the law is observed" "in the interpretation and application" of the Treaties of the European Union.
