European Union Law
Summary
European Union law constitutes the legal framework that governs the EU as a unique supranational order. It arises from founding treaties that confer legislative, executive and judicial powers on EU institutions—principally the European Commission, Parliament, Council of the EU and Court of Justice—and interacts closely with the legal systems of member states. Primary sources include the Treaty on European Union and the Treaty on the Functioning of the European Union, while secondary law comprises regulations, directives and decisions. Regulations apply directly and uniformly, directives set policy objectives for national transposition, and decisions bind their addressees. Core principles of direct effect, supremacy over conflicting national law, proportionality and subsidiarity guide interpretation and ensure consistent application. Through the preliminary‐ruling procedure, the Court of Justice maintains legal coherence. Over decades EU law has expanded from economic integration and the single market to protect fundamental rights, environmental standards, digital governance and social policies. It operates through multilevel governance, balancing collective rule‐making with national discretion. Internationally, it shapes trade norms, climate frameworks and data‐protection standards. Contemporary research focuses on implementation dynamics, differentiated integration, enforcement strategies and adapting to digital transformation while preserving legitimacy in an evolving polity.
