Principle of conferral The Principle of conferral is a foundational rule in European Union constitutional framework allocating powers from member states to the EU via treaties, treaties such as the Treaty of Paris (1951), Treaty of Rome (1957), Treaty on European Union and the Treaty on the Functioning of the European Union. It anchors competence distribution among entities including the European Commission, European Parliament, European Council, Council of the European Union, Court of Justice of the European Union and member states such as France, Germany, Italy, United Kingdom (historical), Spain and Poland. The principle intersects with instruments and actors like the Maastricht Treaty, Lisbon Treaty, Schengen Agreement, Single European Act and institutions including the European Central Bank, European Court of Auditors, European Investment Bank and national constitutional courts such as the Bundesverfassungsgericht, Conseil constitutionnel and the Corte Suprema di Cassazione.

Definition and Legal Basis

The legal basis appears explicitly in the Treaty on European Union and the Treaty on the Functioning of the European Union, and historically in the Treaty of Rome (1957), the Maastricht Treaty and the Lisbon Treaty. The principle holds that the EU may act only within competences conferred by member states, a rule applied by organs like the European Commission and adjudicated by the Court of Justice of the European Union in cases involving parties such as Ireland, Belgium, Netherlands and Greece. Foundational texts include instruments negotiated at events such as the Treaty of Nice and the Treaty of Amsterdam, with doctrinal elaboration by scholars connected to institutions like the College of Europe and the European University Institute.

Historical Development

Origins trace to post‑war arrangements including the Treaty of Paris (1951) creating the European Coal and Steel Community and the Treaty of Rome (1957) establishing the European Economic Community. Subsequent milestones—Single European Act, Maastricht Treaty, Amsterdam Treaty, Nice Treaty and Lisbon Treaty—refined conferral alongside policy projects like the Common Agricultural Policy, the Common Fisheries Policy, the European Monetary System and the Economic and Monetary Union. Judicial elaboration emerged through cases involving parties such as Germany before the Court of Justice of the European Union and national reviews by courts including the Bundesverfassungsgericht and the Supreme Court of the United Kingdom in litigation related to instruments like the European Communities Act 1972 and events such as Brexit.

Application in European Union Law

In practice the principle directs allocation among exclusive competences (eg Common Commercial Policy, Customs Union), shared competences (eg Internal Market, Environment, Transport), and supporting competences (eg Culture, Public Health), categories formalised in the Treaty on the Functioning of the European Union. Institutions such as the European Commission, European Parliament and Council of the European Union legislate, while enforcement involves the Court of Justice of the European Union, national courts like the Conseil d'État (France) and oversight by bodies such as the European Court of Auditors. Member states including Sweden, Denmark, Finland and Austria have invoked conferral in disputes over directives, regulations and decisions involving sectors like Justice and Home Affairs and programmes such as Horizon 2020 and the Common Foreign and Security Policy.

Limits and Scope of Competences

Conferral limits are expressed through treaty text, preserved by national constitutional norms in states such as Poland and Czech Republic and contested in cases involving Hungary and Slovakia. The scope differentiates exclusive competence (eg Customs Union), shared competence (eg Transport), and complementary action (eg Industry). Constraints arise from instruments like the European Charter of Fundamental Rights, fiscal rules related to the Stability and Growth Pact, and conditionalities in agreements with external partners such as Norway, Switzerland, Turkey and accession candidates like Serbia and North Macedonia.

Interaction with Subsidiarity and Proportionality

The principle operates alongside subsidiarity and proportionality as articulated in treaties and enforced by the Court of Justice of the European Union and national courts including the Supreme Court of Ireland and the Tribunal Supremo (Spain). Subsidiarity instruments include early warning mechanisms involving national parliaments such as the Bundesrat and chambers of the Italian Parliament, while proportionality is tested in litigation involving policies like Common Agricultural Policy reform, EU competition law enforcement by the European Commission against firms such as Microsoft and Google and measures in response to crises involving European Stability Mechanism operations.

Key Case Law and Precedents

Principal CJEU judgments shaping doctrine include Van Gend en Loos v Nederlandse Administratie der Belastingen, Costa v ENEL, Köbler v Austria, Commission v Luxembourg and later rulings such as Portugal v Council, United Kingdom v Council, Chernobyl case (Commission v UK), and landmark decisions like Opinion 2/13 and Opinion 1/91 concerning competence and external relations. National constitutional jurisprudence includes judgments from the Bundesverfassungsgericht (eg Solange I and Brunner v European Central Bank rulings), the Conseil constitutionnel (eg Decision No. 98-408 DC), the Supreme Court of the United Kingdom and the Constitutional Court of Italy. International agreements and accession jurisprudence have been influenced by disputes involving European Economic Area partners and cases referencing instruments such as the European Convention on Human Rights adjudicated by the European Court of Human Rights.
