The Court of Justice of the European Union (CJEU) is the highest court in the European Union (EU) that ensures EU laws are interpreted and applied consistently across all member states. It helps resolve legal disputes between EU institutions, member countries, and individuals, making sure that everyone follows the same rules. Located in Luxembourg, the CJEU consists of two main courts: the Court of Justice and the General Court. The Court of Justice primarily handles cases brought by national courts and EU institutions, while the General Court deals with cases involving individuals and businesses. Together, they uphold the rule of law within the EU.
