European law is the body of supranational and regional legal norms, institutions, treaties, and judicial decisions that govern relations among European Union Member States, European Economic Area, and associated entities such as the European Free Trade Association. It encompasses primary treaties like the Treaty on European Union and the Treaty on the Functioning of the European Union, secondary legislation such as regulation (European Union), directive (European Union), and decisions, and a dense jurisprudence produced by the Court of Justice of the European Union. European law shapes policy across areas including the single market, competition law, state aid (EU), and data protection while interacting with national constitutions such as the Basic Law for the Federal Republic of Germany and constitutional courts like the Constitutional Court of Italy.

History

The legal architecture developed from post‑World War II projects like the Treaty of Paris (1951) establishing the European Coal and Steel Community and the Treaty of Rome (1957) creating the European Economic Community, through enlargements including the United Kingdom accession to the European Communities (1973) and the Treaty of Maastricht which founded the European Union. Subsequent milestones include the Single European Act (1986), the Treaty of Lisbon, and the incorporation of the Schengen Agreement and the Charter of Fundamental Rights of the European Union into the legal order. Judicial milestones such as the Van Gend en Loos and Costa v ENEL rulings by the European Court of Justice established doctrines of direct effect and supremacy that reconfigured relations with national legal systems and influenced national courts like the Conseil d'État (France) and the Supreme Court of the United Kingdom.

Sources and Legal Framework

Primary sources derive from treaties including the Treaty on European Union and the Treaty on the Functioning of the European Union, alongside foundational documents like the Maastricht Treaty and the Treaty of Nice. Secondary sources comprise regulation (European Union), directive (European Union), decisions, and acts of agencies such as the European Central Bank and the European Banking Authority. Soft law instruments, communications from the European Commission, and international agreements like the European Economic Area Agreement and the EU–US Privacy Shield (invalidated by the Schrems I and Schrems II contexts) also shape obligations. Doctrines articulated by the Court of Justice of the European Union—including direct effect, supremacy, and state liability—operate alongside national constitutional case law from courts such as the Bundesverfassungsgericht and the Constitutional Council (France).

Institutions and Enforcement

Key institutions include the European Commission as the executive guardian of the treaties, the Council of the European Union representing Member States, the European Parliament as a directly elected legislature, and the Court of Justice of the European Union as the judicial arbiter. Economic governance involves the European Central Bank, the European Stability Mechanism, and the European Investment Bank; regulatory enforcement engages agencies like the European Medicines Agency and the European Chemicals Agency. Enforcement actions can be initiated by the European Commission through infringement procedures leading to preliminary reference questions from national courts under Article 267 TFEU, and fines imposed pursuant to competition law adjudication by the General Court (European Union).

Areas of Law and Policy

Major substantive fields include the internal market (freedom of movement for goods, services, capital, and persons), competition law, state aid (EU), trade policy, and monetary policy within the Economic and Monetary Union. Social and fundamental rights areas feature employment law, social policy, environmental law, and data protection as embodied in the General Data Protection Regulation. External relations encompass common foreign and security policy and trade agreements such as the EU–Japan Economic Partnership Agreement and the Comprehensive Economic and Trade Agreement negotiation with Canada. Sectoral regulation addresses telecommunications, energy policy, agricultural policy under the Common Agricultural Policy, and financial services under frameworks like MiFID II and Bank Recovery and Resolution Directive.

Relationship with Member State Law

The legal order interacts with national systems through doctrines of supremacy and direct effect established by cases such as Costa v ENEL and Van Gend en Loos, obliging national authorities and courts to give precedence to EU norms. Tensions arise where national constitutional courts—exemplified by the Bundesverfassungsgericht and the Polish Constitutional Tribunal—contest EU measures, producing dialogue mechanisms like preliminary references and political responses including treaty revision or opt‑outs such as those held by the United Kingdom prior to Brexit and by Denmark. Implementation of directives relies on national transposition, while regulations apply uniformly, affecting domestic legal instruments including codes and statutes within Member States like France, Spain, and Sweden.

Judicial System and Case Law

The judiciary is anchored by the Court of Justice of the European Union and its chamber, the General Court (European Union), supplemented by the Civil Service Tribunal (historical) and specialized tribunals. Case law—ranging from foundational decisions like Costa v ENEL, Van Gend en Loos, and Francovich v Italy to recent rulings in Schrems II—creates binding principles for national courts and agencies. Preliminary rulings under Article 267 TFEU enable national courts such as the Supreme Court of Ireland and the Supreme Court of the Netherlands to seek interpretive guidance, producing a cohesive jurisprudence that regulates remedies, liability, and the scope of competences.

Criticisms and Reform debates

Critiques address democratic legitimacy (role of the European Commission and European Parliament), accountability of technocratic bodies like the European Central Bank, complexity of the acquis and subsidiarity controversies involving the Council of the European Union, and perceived overreach in areas contested by national constitutional courts. Reform proposals range from treaty amendment initiatives championed by actors such as the European Council to sectoral regulatory overhaul in response to cases like Google v CNIL and policy priorities articulated by the Conference on the Future of Europe. Debates engage legal scholars from institutions like European University Institute and advocacy groups including European Consumer Organisation and judicial actors within national judiciaries.
