# Article 263 TFEU Explained: The Action for Annulment URL: https://eu-now.com/blog/article-263-tfeu-action-annulment-explained Published: 2026-07-11 · Updated: 2026-08-28 Category: Guides Tags: TFEU, Article 263, annulment, Court of Justice, EU Knowledge, EPSO How EU acts get struck down: reviewable acts, the four grounds, privileged vs individual applicants and the two-month limit — Article 263 for EPSO candidates. ## Key takeaways - Article 263 TFEU lets the Court of Justice review the legality of EU acts intended to produce legal effects — and strike them down - Four grounds, worth memorising verbatim: lack of competence, infringement of an essential procedural requirement, infringement of the Treaties or any rule of law relating to their application, and misuse of powers - Applicants come in tiers: Member States, Parliament, Council and Commission sue as of right; individuals must show the act is addressed to them or of direct and individual concern - The action must be brought within two months — one of the tightest deadlines in the treaty system [Article 258](/blog/article-258-tfeu-infringement-procedure-explained) polices Member States and [Article 267](/blog/article-267-tfeu-preliminary-rulings-explained) keeps interpretation uniform — but who polices the EU institutions themselves? That is Article 263 TFEU: the **action for annulment**, the procedure through which the Court of Justice strikes down unlawful EU acts. It completes the judicial-protection triangle, and the [EU Knowledge test](/test/eu_knowledge) treats the trio as one connected syllabus. ## What can be annulled The consolidated text (OJ C 202) gives the Court jurisdiction to "review the **legality** of legislative acts, of acts of the Council, of the Commission and of the European Central Bank, **other than recommendations and opinions**, and of acts of the European Parliament and of the European Council intended to produce **legal effects vis-à-vis third parties**" — plus acts of Union bodies, offices and agencies with such effects. Two details carry exam weight. The carve-out for recommendations and opinions is pure [Article 288](/blog/article-288-tfeu-legal-acts-explained) logic: no binding force, nothing to annul. And the "legal effects vis-à-vis third parties" filter explains why internal or purely political acts escape review — the question is always whether the act changes someone's legal position. ## The four grounds Annulment actions must stand on one of four grounds, and the list is worth knowing by heart because EPSO tests it as a list: 1. **Lack of competence** — the institution had no power to adopt the act. 2. **Infringement of an essential procedural requirement** — a mandatory procedural step was violated: the wrong [legislative procedure](/blog/article-294-tfeu-ordinary-legislative-procedure-explained), a skipped consultation, missing reasons. 3. **Infringement of the Treaties or of any rule of law relating to their application** — the broad substantive ground, covering everything from treaty articles to general principles and fundamental rights. 4. **Misuse of powers** — a power exercised for purposes other than those for which it was conferred. The classic distractor inserts a plausible fifth ground ("manifest error of political judgment", "breach of national constitutional law") or deletes one of the four. If a question shows you this list, count and verify. ![The three actions before the Court of Justice side by side: Article 258 infringement, Article 263 annulment and Article 267 preliminary ruling, each with who brings it and against what.](/photos/blog/tfeu-judicial-triangle.en.svg) ## Who can sue — the three tiers **Privileged applicants** — Member States, the European Parliament, the Council and the Commission — may challenge any reviewable act, no interest required. **Semi-privileged applicants** — the Court of Auditors, the European Central Bank and the Committee of the Regions — may sue *to protect their own prerogatives*. **Non-privileged applicants** — natural and legal persons — face the narrow gate: they may challenge acts **addressed to them**, acts of **direct and individual concern** to them, and **regulatory acts of direct concern not entailing implementing measures** (the Lisbon addition that slightly widened the gate). The "individual concern" test is famously strict, which is why the realistic route for individuals against EU-law problems usually runs through national courts and [Article 267](/blog/article-267-tfeu-preliminary-rulings-explained) — a connection sophisticated exam questions expect you to make. ## The clock and the consequence The action must be instituted within **two months** of the act's publication, notification, or the applicant's knowledge of it. If the action succeeds, the act is declared **void** — erased from the legal order, with the Court able to preserve specific effects where legal certainty demands. ## The two articles it is confused with **Article 265 — the mirror image.** Article 263 attacks something the institutions *did*; Article 265 attacks something they failed to do. The action for failure to act requires the institution first to be called upon to act, and it is admissible only if the institution has not defined its position within two months of being called upon. A statement that uses Article 263 to compel an institution into action has inverted the pair. **Article 267 — validity from below.** Both articles can end with an EU act being found invalid, which is why they blur. The difference is the door. Under 263 an applicant sues directly, within two months, and must clear the standing tiers. Under [Article 267](/blog/article-267-tfeu-preliminary-rulings-explained) a national court refers the question of validity upward, with no standing requirement on the individual and no two-month clock — because the dispute is a national one and the question of EU law is incidental to it. That is precisely why 267 matters to applicants who could never satisfy the individual-concern test in 263. ## The exam patterns **Ground-list manipulation** — the invented fifth ground or the missing fourth. **Applicant inflation** — "any individual may challenge any EU regulation": false; the Plaumann gate stands. **Reviewability errors** — annulling a recommendation (nothing to annul) or immunising the European Council (its acts with third-party legal effects are reviewable since Lisbon). **Deadline drift** — six months, one year: no; **two months**. Test the triangle — 258 enforces, 267 interprets, 263 annuls — against [free weekly EU Knowledge questions](/test/eu_knowledge), and place judicial protection in your plan with the [EPSO Preparation 2026 complete guide](/blog/epso-preparation-guide-2026). ## FAQ ### Which acts can be annulled under Article 263? The Court reviews the legality of legislative acts; of acts of the Council, the Commission and the European Central Bank other than recommendations and opinions; and of acts of the European Parliament, the European Council and of Union bodies, offices or agencies intended to produce legal effects vis-à-vis third parties. The exclusion is logical: recommendations and opinions have no binding force (Article 288), so there is nothing to annul. ### What are the four grounds for annulment? Lack of competence (the author had no power to adopt the act); infringement of an essential procedural requirement (a mandatory step — like consulting the Parliament — was skipped); infringement of the Treaties or of any rule of law relating to their application (the catch-all substantive ground); and misuse of powers (a power used for a purpose other than the one it was granted for). EPSO questions frequently present this list with one invented ground swapped in. ### Can individuals challenge EU acts directly? Only within limits — the tightest part of the article. A natural or legal person may challenge an act addressed to them, an act of direct and individual concern to them, and a regulatory act which is of direct concern and does not entail implementing measures. That 'direct and individual concern' formula (the Plaumann case-law) makes direct individual challenges to general legislation exceptionally hard; the ordinary route for individuals runs through national courts and the preliminary ruling of Article 267. ### What is the deadline for an annulment action? Two months from publication of the act, its notification to the applicant or, failing that, from the day the applicant had knowledge of it. Miss the window and the act becomes unchallengeable by this route — which is why the two-month figure is one of the most tested numbers in the judicial-protection syllabus. ## Official sources - EUR-Lex — Consolidated version of the TFEU (OJ C 202, 7.6.2016): https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex%3A12016E%2FTXT - EU Careers — EPSO testing (official): https://eu-careers.europa.eu/en/selection-procedure/epso-tests ## This article in other languages - French: https://eu-now.com/fr/blog/article-263-tfeu-action-annulment-explained/llms.txt - German: https://eu-now.com/de/blog/article-263-tfeu-action-annulment-explained/llms.txt - Spanish: https://eu-now.com/es/blog/article-263-tfeu-action-annulment-explained/llms.txt - Italian: https://eu-now.com/it/blog/article-263-tfeu-action-annulment-explained/llms.txt Source of record: https://eu-now.com/blog/article-263-tfeu-action-annulment-explained — published by EU-now (eu-now.com), which is not EPSO and not affiliated with the European Commission.
