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 Court operates as the supreme authority on questions of EU law, and its judgments are binding on national courts and institutions throughout the Union.
The CJEU is based in Luxembourg and forms a central pillar of the EU's institutional framework. Its existence and mandate are grounded in the founding treaties of the European Union, and it plays an essential role in maintaining the rule of law within the EU legal order.
Structure of the Court
The Court of Justice of the European Union is composed of two principal courts: the Court of Justice itself and the General Court. Each of these bodies has a distinct jurisdiction and handles different categories of cases arising under EU law.
The Court of Justice deals primarily with 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, handles direct actions brought by individuals, companies, and, in certain circumstances, member states, particularly in areas such as competition law, state aid, trade, and intellectual property.
Judges and Advocates General are appointed to the Court of Justice by common accord of the governments of the member states. The Advocates General assist the Court by delivering impartial opinions on cases before judgment is rendered, contributing to the transparency and legal reasoning of the Court's decisions.
The preliminary ruling procedure
One of the most significant mechanisms through which the CJEU operates is the preliminary ruling procedure. Under this procedure, national courts of EU member states may — and in certain circumstances must — refer questions of EU law to the Court of Justice for interpretation before delivering their own judgments.
This mechanism ensures consistency in the application of EU law across all member states. When a national court is uncertain about the meaning or validity of a provision of EU law, it suspends its proceedings and submits the question to the CJEU. The Court's ruling on that question is then binding on the referring court and, by extension, guides the interpretation of EU law in similar cases across the Union.
The preliminary ruling procedure is a cornerstone of the cooperative relationship between the CJEU and national judiciaries, reinforcing the uniform application of EU law throughout the member states.
Accessing EU legal texts through EUR-Lex
EUR-Lex is the official portal providing free public access to European Union law. It is maintained by the Publications Office of the European Union and serves as the authoritative online source for EU legal documents, including treaties, regulations, directives, decisions, and case law.
Through EUR-Lex, users can access the Official Journal of the European Union, which is the publication in which all binding EU legal acts are formally published. The Official Journal 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 accessible to all citizens of the Union.
EUR-Lex also provides access to preparatory acts, international agreements, and consolidated versions of EU legislation, making it an essential resource for legal professionals, academics, public authorities, and citizens seeking to understand their rights and obligations under EU law.
The relationship between the CJEU and EUR-Lex
The judgments and orders of the Court of Justice of the European Union are published and made publicly accessible through both the CJEU's own website and EUR-Lex. This dual availability ensures that the Court's jurisprudence is transparent and accessible to all those with an interest in EU law.
The CJEU's case law, as published through these official channels, forms an integral part of the EU legal order. National courts, legal practitioners, and institutions across the member states rely on these published judgments to understand how EU law is to be interpreted and applied in practice.
Together, the CJEU and EUR-Lex represent the judicial and documentary foundations of the EU legal system, providing both the authoritative interpretation of EU law and the means by which that law — and its interpretation — is made publicly available.
Why this matters for understanding EU law
Understanding the role of the CJEU and the function of EUR-Lex is fundamental to engaging with EU law in any meaningful way. Whether one is a student of law, a legal professional, a business operating across borders within the EU, or a citizen seeking to understand their rights, these institutions and resources provide the authoritative framework within which EU law operates.
The CJEU's judgments shape the practical meaning of EU legislation, while EUR-Lex ensures that both the legislation and its judicial interpretation remain publicly accessible. This combination of judicial authority and documentary transparency is central to the rule of law in the European Union.
