Delegated and Implementing Acts: Articles 290–291 TFEU

Articles 290 and 291 TFEU, introduced by the Treaty of Lisbon, establish a hierarchy of EU legal acts by distinguishing between delegated acts and implementing acts. The distinction addresses the constitutional relationship between the legislature (Parliament and Council) and the executive (primarily the Commission). Articles 290 and 291 replaced the pre-Lisbon comitology system with a new constitutional framework that separates the delegation of legislative power from the conferral of implementing powers. The distinction has generated significant litigation as institutions and Member States have contested the boundary between the two categories.

Delegated Acts under Article 290 TFEU

Article 290(1) TFEU provides that a legislative act may delegate to the Commission the power to adopt non-legislative acts of general application to supplement or amend certain non-essential elements of the legislative act. The delegation is subject to two fundamental limits. First, the essential elements of an area must be reserved for the legislative act and cannot be delegated. Second, the delegation must be expressly defined as to objectives, content, scope, and duration.

The essential elements doctrine ensures that the legislature retains control over fundamental policy choices. The CJEU has held that essential elements include provisions whose adoption requires political choices falling within the responsibility of the EU legislature (European Parliament v Council (Biocides), Case C-427/12). Measures that implement the basic policy choices of the legislative act and do not require further political choices may be delegated. The determination of whether a matter is essential is subject to judicial review, and the Court has annulled provisions that delegated essential elements to the Commission.

Article 290(2) TFEU requires that legislative acts explicitly lay down the conditions of delegation. These conditions may include the power of the Parliament or Council to revoke the delegation, a time limit on the delegation, or an objection procedure under which delegated acts enter into force only if no objection is raised within a specified period. The Parliament and Council each have the right to revoke delegation or object to delegated acts, exercising democratic control over the exercise of delegated powers.

Implementing Acts under Article 291 TFEU

Article 291 TFEU addresses implementing acts, which are adopted where uniform conditions for implementing legally binding Union acts are needed. Article 291(2) provides that the Commission, or in duly justified specific cases and in cases provided for in Articles 24 and 26 TEU (CFSP), the Council, is conferred implementing powers. Implementing acts are executive measures that ensure the uniform application of EU law across Member States.

The comitology system under Article 291(3) TFEU regulates implementing acts. Regulation (EU) No 182/2011 (the Comitology Regulation) establishes two procedures for committees composed of Member State representatives: the examination procedure and the advisory procedure. Under the examination procedure, the Commission may adopt the proposed implementing measure only if the committee delivers a positive opinion by qualified majority. If the committee delivers a negative opinion, the Commission may not adopt the measure. Under the advisory procedure, the Commission adopts the measure but must take the utmost account of the committee’s opinion.

The examination procedure applies to implementing acts of general scope, measures with substantial budgetary implications, and policies in agriculture, fisheries, environment, health and safety, and trade. The advisory procedure applies in all other cases, particularly where the implementing act has limited scope. The Comitology Regulation also establishes an appeal committee to review implementing measures where the examination committee delivers no opinion and the measure concerns sensitive policy areas.

Distinction Between Delegated and Implementing Acts

The distinction between Articles 290 and 291 TFEU has been one of the most contested issues in EU constitutional law. Delegated acts supplement or amend non-essential elements of legislative acts, while implementing acts provide uniform conditions for implementation. The CJEU has provided guidance on the distinction in several important judgments.

In Commission v Parliament and Council (Case C-427/12, Biocides), the Court held that the choice between Articles 290 and 291 depends on whether the measure supplements or amends the legislative act. Implementing acts cannot amend legislative acts, even non-essential elements. In Commission v Parliament and Council (Case C-88/14, Visa reciprocity), the Court held that the legislature must respect the constitutional choices made by the Treaties and cannot freely choose between Articles 290 and 291.

In European Parliament v Council (Case C-65/13, Securitisation), the Court annulled a provision that conferred implementing powers on the Commission under Article 291 where the measure should have been adopted as a delegated act under Article 290. The Court emphasised that the choice between the two provisions depends on objective factors amenable to judicial review, not on the discretion of the legislature. The case confirms that the constitutional distinction is judicially enforceable.

The ESMA Short Selling Case

The UK v Parliament and Council (Case C-270/12, ESMA Short Selling) case is a landmark judgment on the limits of delegated and implementing powers. The UK challenged provisions of Regulation (EU) No 236/2012 on short selling that conferred powers on the European Securities and Markets Authority (ESMA) to adopt emergency measures, including prohibiting short selling, arguing that such powers could not be delegated to an agency under the Meroni doctrine.

The CJEU rejected the UK’s challenge, holding that the ESMA powers were consistent with the Treaties. The Court distinguished Meroni by noting that the ESMA powers were precisely defined, subject to judicial review, and limited to specific circumstances. The Court also held that Article 114 TFEU could provide a legal basis for conferring decision-making powers on agencies where the powers were necessary for the harmonisation of national laws and were subject to appropriate limits. The ESMA Short Selling judgment marked a significant development in EU agency law, allowing greater delegation of powers to agencies than had previously been thought permissible under the Meroni criteria.

The Comitology Regulation

The Comitology Regulation (Regulation (EU) No 182/2011) establishes the procedural framework for implementing acts. The regulation replaced the pre-Lisbon comitology system with a simplified structure that distinguishes between examination and advisory procedures. The examination procedure applies to implementing acts of general scope and certain specific categories. The advisory procedure applies to all other implementing acts. The regulation also gives the European Parliament and Council a right of scrutiny over draft implementing acts, allowing either institution to indicate that a draft exceeds the implementing powers provided for in the legislative act.

The regulation establishes an Appeal Committee composed of Member State representatives at senior level, chaired by the Commission. If the examination committee delivers no opinion, the Commission may adopt the implementing measure, except for specific sensitive areas (consumer protection, health, safety, and certain financial services) where the measure may not be adopted without a positive opinion. The Appeal Committee may be convened to reconsider the measure. The system balances the Commission’s executive role with Member State oversight through committee participation.
