The Court of Justice of the European Union (CJEU) is the judicial body of the EU that makes decisions on issues of EU law and enforces European decisions either in respect to actions taken by the European Commission against a member state or actions taken by individuals to enforce their rights under EU law. The CJEU consists of two courts: the Court of Justice and the General Court. The CJEU ensures the uniform interpretation and application of EU law across the EU and settles disputes between EU institutions, member states, and individuals.
The other options are not correct, as they are not the judicial bodies that make decisions on actions taken by individuals wishing to enforce their rights under EU law. The Court of Auditors is the EU's independent external auditor that checks the legality and regularity of the EU's revenue and expenditure, and the soundness of its financial management. The European Court of Human Rights (ECHR) is an international court that oversees the European Convention on Human Rights and Fundamental Freedoms of 1950. The ECHR is not linked to the EU institutions, and it covers human rights laws across Europe, including in many non-EU countries. The European Data Protection Board (EDPB) is an independent body that ensures the consistent application of the GDPR and issues opinions on various aspects of data protection, but it does not have judicial authority.
