  The judicial branch of the European Union is formally called the Court of Justice of the European Union (CJEU) and consists of two courts: the Court of Justice and the General Court. The Court of Justice is the supreme court of the European Union in matters of European Union law. As a part of the CJEU, it is tasked with interpreting EU law and ensuring its uniform application across all EU member states under Article 263 of the Treaty of the Functioning of the European Union (TFEU). The Court was established in 1952, and is based in Luxembourg. It is composed of one judge per member state – currently 27 – although it normally hears cases in panels of three, five or fifteen judges. The Court has been led by president Koen Lenaerts since 2015. The CJEU is the highest court of the European Union in matters of Union law. Its case-law provides that EU law has supremacy over any national law that is inconsistent with EU law. It is not possible to appeal against the decisions of national courts in the CJEU, but rather national courts refer questions of EU law to the CJEU. However, it is ultimately for the national court to apply the resulting interpretation to the facts of any given case. Although, only courts of final appeal are bound to refer a question of EU law when one is addressed. The treaties give the CJEU the power for consistent application of EU law across the EU as a whole. The court also acts as an administrative and constitutional court between the other EU institutions and the Member States and can annul or invalidate unlawful acts of EU institutions, bodies, offices and agencies.
  
  The General Court is a constituent court of the European Union. It hears actions taken against the institutions of the European Union by individuals and member states, although certain matters are reserved for the Court of Justice. Decisions of the General Court can be appealed to the Court of Justice, but only on a point of law. Prior to the coming into force of the Lisbon Treaty on 1 December 2009, it was known as the Court of First Instance.
