Introduction to the Court of Justice of the European Union
The Court of Justice of the European Union (CJEU) is the judicial institution of the European Union. It is responsible for ensuring that EU law is interpreted and applied uniformly across all member states. The CJEU plays a central role in the EU's legal order, resolving disputes between member states, EU institutions, businesses, and individuals where EU law is engaged.
The official web presence of the CJEU is maintained at curia.europa.eu, which serves as the primary portal for accessing information about the court's composition, jurisdiction, procedures, and case law. This platform is an authoritative source for anyone seeking to understand how the court operates and how its decisions are made publicly available.
Structure of the CJEU
The Court of Justice of the European Union is not a single court but rather an institution comprising distinct judicial bodies. According to the official CURIA portal, the institution includes the Court of Justice itself, the General Court, and, historically, specialised courts. Each body has its own jurisdiction and procedural rules, allowing the institution as a whole to handle a wide range of legal matters arising under EU law.
The Court of Justice handles the most significant matters, including references for preliminary rulings from national courts, actions for failure to fulfil obligations brought against member states, and appeals from the General Court. The General Court, in turn, deals with direct actions brought by individuals, companies, and, in some cases, member states, particularly in areas such as competition law, state aid, and EU trademark matters.
Judges and Advocates General are appointed to the Court of Justice, with Advocates General playing a distinctive role by delivering impartial opinions on cases before the court issues its judgment. These opinions, while not binding, are influential in shaping the court's reasoning and are publicly accessible through the CURIA portal.
The preliminary ruling procedure
One of the most significant mechanisms through which the CJEU interacts with national legal systems is the preliminary ruling procedure. Under this procedure, national courts of EU member states may — and in some cases must — refer questions of EU law to the Court of Justice when such questions are necessary to resolve a dispute before them.
This mechanism ensures consistency in the interpretation of EU law across all member states. A ruling issued by the Court of Justice in response to a preliminary reference is binding on the referring national court and, by extension, guides the application of EU law throughout the member states. Information about this procedure and access to relevant case law is available through the CURIA portal.
Accessing EU law through EUR-Lex
EUR-Lex is the official portal providing free public access to European Union law. Maintained by the Publications Office of the European Union, EUR-Lex offers access to the full text of EU treaties, regulations, directives, decisions, and other legislative and non-legislative acts. It also provides access to the Official Journal of the European Union, which is the authoritative publication for EU legal acts.
The EUR-Lex platform is available in all official languages of the European Union, reflecting the multilingual character of EU law and the principle that EU legislation must be equally authentic in each official language. This accessibility is fundamental to ensuring that citizens, legal practitioners, businesses, and public authorities across member states can consult the legal texts that govern their rights and obligations.
In addition to legislative texts, EUR-Lex provides access to preparatory acts, international agreements to which the EU is a party, and case law from the Court of Justice of the European Union. This makes EUR-Lex a comprehensive resource for understanding not only what EU law says but also how it has been interpreted and applied by the CJEU.
The relationship between CURIA and EUR-Lex
The CURIA portal and EUR-Lex serve complementary functions within the EU's framework for legal transparency and public access. CURIA focuses specifically on the judicial institution — providing information about the court's composition, procedures, statistics, and the full text of its judgments, orders, and Advocate General opinions. EUR-Lex, by contrast, offers a broader legislative and regulatory repository covering the entire body of EU law.
Together, these two official platforms enable users to trace the full lifecycle of an EU legal provision — from its legislative origins and text as published in the Official Journal, through to its judicial interpretation by the Court of Justice. Both platforms are freely accessible to the public, consistent with the EU's commitment to openness and transparency in its legal processes.
Why these sources matter for legal understanding
For anyone seeking to understand EU law — whether as a student, researcher, legal professional, or interested citizen — the CURIA portal and EUR-Lex represent the most reliable and authoritative starting points. Because they are maintained by EU institutions themselves, the information they contain reflects the official position of those institutions and is not subject to the editorial interpretation that may affect secondary sources.
Consulting these official sources directly allows users to read legislative texts as enacted, access judgments as delivered by the court, and understand procedural rules as officially published. This is particularly important in a legal system as complex and multilayered as that of the European Union, where the interaction between EU law and national law can have significant practical consequences for individuals and organisations alike.
