Court of Justice of the European Union
Introduction The '''Court of Justice of the European Union''' ('''CJEU''') ( or "''CJUE''"; Latin: '''Curia''') is the judicial branch of the European Union (EU). Seated in the Kirchberg quarter of Luxembourg City, Luxembourg, this EU institution consists of two separate courts: the Court of Justice and the General Court. From 2005 to 2016, it also contained the Civil Service Tribunal. It has a ''sui generis'' court system, meaning 'of its own kind', and is a supranational institution.The CJEU is the chief judicial authority of the European Union and oversees the uniform application and interpretation of European Union law, in co-operation with the national judiciary of the member states. The CJEU also resolves legal disputes between national governments and EU institutions, and may take action against EU institutions on behalf of individuals, companies or organisations whose rights have been infringed.
Composition The CJEU consists of two major courts:# the '''Court of Justice''', informally known as '''European Court of Justice (ECJ)''', which hears applications from national courts for preliminary rulings, annulment and appeals. It consists of one judge from each EU member country, as well as 11 advocates general.# the '''General Court''', which hears applications for annulment from individuals, companies and, less commonly, national governments (focusing on competition law, state aid, trade, agriculture and trade marks). Since 2020 the court is composed of 54 judges, though only 49 seats are currently filled.
Function 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. To achieve this, it:* reviews the legality of actions taken by the EU's institutions;* enforces compliance by member states with their obligations under the Treaties, and* interprets European Union law.The composition and functioning of the courts are regulated by the Rules of Procedure.
History The CJEU was originally established in 1951 as a single court called the '''Court of Justice of the European Coal and Steel Communities.''' With the Euratom and the European Economic Community in 1957 its name changed to the '''Court of Justice of the European Communities''' ('''CJEC''')). In 1988 the Court requested the Commission to create a Court of First Instance and in 2004 it added the Civil Service Tribunal. The Civil Service Tribunal are for issues of public employment. The Treaty of Lisbon in 2009 renamed the court system to the "Court of Justice of the European Union" and renamed the CJEC to the "Court of Justice".The working language of the Court of Justice of the European Union is French.
