Judicial Review of EU Acts under Article 263 TFEU

The action for annulment under Article 263 TFEU is the principal mechanism for the judicial review of the legality of EU acts. It enables the Court of Justice of the European Union to review the lawfulness of legislative, regulatory, and administrative acts of EU institutions, bodies, offices, and agencies. The procedure is the constitutional remedy of EU law, analogous to judicial review in national legal systems, ensuring that EU institutions act within the limits of their powers and respect the rule of law.

Reviewable Acts

Article 263 TFEU permits review of “legislative acts, acts of the Council, of the Commission, and of the European Central Bank, other than recommendations and opinions, and acts of the European Parliament and of the European Council intended to produce legal effects vis-à-vis third parties.” The CJEU has interpreted this broadly to include any measure that produces binding legal effects, regardless of its form or designation.

The Plaumann doctrine on reviewable acts, established in ERTA (Case 22/70), provides that an action for annulment lies against all measures adopted by institutions that are intended to have legal effects. This includes regulations, directives, decisions, and atypical acts such as communications, guidelines, and notices that produce legal effects. Acts of bodies, offices, and agencies of the Union are reviewable under Article 263(5) where they are intended to produce legal effects. Non-binding acts such as recommendations, opinions, and purely internal measures are not reviewable.

Standing Requirements

Article 263 TFEU distinguishes between three categories of applicants with different standing requirements. Privileged applicants — Member States, the European Parliament, the Council, and the Commission — may bring an action without having to demonstrate any interest or standing. They are deemed to have an institutional interest in the legality of EU measures. The Court of Auditors, the European Central Bank, and the Committee of the Regions are semi-privileged applicants: they may bring actions only to protect their own prerogatives.

Non-privileged applicants — natural and legal persons — face more restrictive standing requirements. Under Article 263(4), an individual may challenge: an act addressed to that person; a regulatory act that is of direct concern to them and does not entail implementing measures; or a legislative act that is of direct and individual concern to them. The distinction between regulatory and legislative acts, introduced by the Treaty of Lisbon, reflects the different democratic legitimacy of legislative acts adopted through the ordinary legislative procedure.

The Plaumann test for individual concern, established in Plaumann v Commission (Case 25/62), requires that the applicant be affected by reason of certain attributes peculiar to them or by circumstances that differentiate them from all other persons, thereby individualising them in the same way as the addressee. This test is notoriously strict: it has been described as making it nearly impossible for individuals to challenge general acts unless they are part of a closed class. The General Court attempted to liberalise standing in Jégo-Quéré (Case T-177/01), but the CJEU reaffirmed the Plaumann test in UPA (Case C-50/00 P), emphasising that the EU legal order provides alternative remedies including preliminary references on validity.

Direct concern requires that the contested measure directly affect the legal position of the applicant and leave no discretion to the addressees charged with its implementation. Where implementation is automatic or leaves no real discretion, the measure is of direct concern. Where the Member State has discretion, the measure is not of direct concern unless the state applies the measure exactly as required.

Grounds for Review

Article 263(2) TFEU sets out four grounds for review. Lack of competence concerns whether the EU institution had the legal authority to adopt the measure, reflecting the principle of conferral under Article 5 TEU. Infringement of an essential procedural requirement covers procedural irregularities including inadequate reasoning (Article 296 TFEU), failure to consult as required, failure to publish or notify, and breach of the right to be heard. The duty to give reasons requires that the measure disclose in a clear and unequivocal fashion the reasoning of the institution so that the CJEU can review its legality and the person concerned can understand the grounds.

Infringement of the Treaties or of any rule of law relating to their application is the broadest ground, covering violations of primary law, general principles of EU law including proportionality, legal certainty, legitimate expectations, fundamental rights, and the Charter of Fundamental Rights. Misuse of powers (détournement de pouvoir) requires that the institution adopted the measure for purposes other than those for which it was granted, a ground that is rarely successful because of the evidentiary burden.

Time Limits and Procedure

Proceedings must be instituted within two months of the publication of the measure, its notification to the applicant, or, in the absence thereof, the day on which it came to the applicant’s knowledge. The time limit is strict and cannot be extended; it is calculated from the fifteenth day after publication in the Official Journal. Late applications are inadmissible unless the delay is excusable under exceptional circumstances.

The action is brought before the General Court, with an appeal on points of law only to the CJEU. The procedure comprises written and oral stages, with the applicant lodging the application and the defendant institution lodging a defence. Interventions by other institutions, Member States, and interested persons are permitted. The Court may adopt interim measures under Articles 278–279 TFEU, suspending the operation of the contested act pending judgment, where the applicant demonstrates urgency and a prima facie case.

Consequences of Annulment

If the action is well founded, the CJEU declares the act void under Article 264 TFEU. The annulment has erga omnes effect: the act is void from the moment of its adoption (ex tunc). The institution concerned is required to take the necessary measures to comply with the judgment under Article 266 TFEU. The Court may, if it considers it necessary, specify which effects of the annulled act are to be considered definitive, preserving legal certainty for past transactions.

The annulment may be total or partial. Where only part of an act is annulled, the Court must determine whether the severable parts can stand independently. If the annulled provision is essential to the act, the entire act falls. The institution may adopt a new act to replace the annulled measure, provided it cures the defect identified by the Court and does not retroactively validate the original act.

Relationship with Other Remedies

The action for annulment forms part of a complete system of legal remedies under the Treaties. It coexists with the plea of illegality under Article 277 TFEU, which enables a party to challenge the applicability of a general act in proceedings before the CJEU, and with the preliminary reference on validity under Article 267 TFEU, which enables national courts to refer questions about the validity of EU acts. The principle of effective judicial protection under Article 47 of the Charter requires that these remedies together provide a complete system of legal protection, as confirmed in Les Verts v Parliament (Case 294/83).
