Competences of the European Union

Distribution of competences in the European Union is the system by which powers and responsibilities are allocated between the European Union (EU) and its member states. Under the EU's founding treaties, the Union may act only within the limits of competences conferred upon it by the member states, while all remaining powers are retained by the member states.

Upon entry into force in 2009, the Treaty of Lisbon clarified and codified the main categories of Union competence, commonly grouped as exclusive, shared, and supporting, coordinating or supplementing competences (Articles 2–6 TFEU). This new system replaced the former pillar system.
