HomeEuropol Litigation Before the CJEU: Understanding Your Legal Rights and Court Remedies
Challenge Europol decisions at the Court of Justice. Expert Europol litigation lawyers. Free consultation: +357 96 447475
If Europol has made a decision affecting you—denying data access, refusing erasure, or sharing your information with third countries—you can challenge it directly before the General Court under Article 263 TFEU. The catch: you have exactly two months from the day you find out about the decision, and you’ll need to show it harms your legal position specifically. We’ve represented clients in multiple General Court cases involving unlawful data processing and proportionality breaches, securing annulments and damages awards across EU Member States.
Europol – the European Union Agency for Law Enforcement Cooperation, established by Regulation (EU) 2016/794, which supports criminal investigations by facilitating information exchange, operating databases containing personal data, and coordinating joint investigations among EU Member States (EUR-Lex, Official Journal L 135, 24 May 2016).
Key Takeaways
- Two-month filing deadline from notification—miss it, and your case is thrown out immediately (Article 263(6) TFEU).
- Kočner v. Europol (2025): Court of Justice awarded €2,000 in non-material damages and confirmed Europol can be held liable for unlawful data disclosure. This matters because it establishes a precedent for damages claims, not just annulments.
- General Court cases T-1180/23 and T-167/24 (hearings on 9 September 2025): applicants challenged fundamental-rights violations during the SkyECC encrypted-service operation. Decisions pending—these cases will likely reshape how courts scrutinize Europol’s operational role in law enforcement.
- Case T-578/22 (6 September 2023): The European Data Protection Supervisor lost standing to challenge the Europol Regulation itself. Only individuals or organisations directly harmed by a specific Europol decision can sue.
- Expect 18–24 months from filing to judgment. Preliminary phases can wrap in two to three months, but full proceedings take patience.
What Legal Powers Does Europol Actually Have That Can Be Challenged in Court?
Europol doesn’t just collect and store data—it processes it, analyses it, shares it with Member States and third countries, and integrates it into live investigations. Regulation (EU) 2016/794 authorizes all of this. That same regulation also requires legal safeguards: Europol must have a lawful basis, respect purpose limitation, and keep data accurate and only as long as needed.
The problem arises when those powers cross the line. Europol processes racial or ethnic origin, political beliefs, religion, biometric data, health records—all “special categories” under Article 18. When that processing happens without clear justification or when data gets shared with third countries lacking equivalent protections, individuals can invoke Articles 7, 8, and 47 of the Charter of Fundamental Rights. The General Court will ask: Did Europol have a legal basis? Was it proportionate? Were safeguards adequate?
Cooperation agreements with third countries and entities like Frontex add another layer of complexity. Data shared under these agreements can end up in jurisdictions where EU protections don’t apply—and Europol doesn’t always make it transparent who controls that data or how it’s used. That jurisdictional fog is where many successful challenges begin.
Can you challenge Europol’s decision-making powers at the Court of Justice?
Yes—but only certain decisions qualify. You need an individual administrative act that directly affects your legal position. That includes: refusal to grant you access to your own data (Article 37), rejection of your erasure request (Article 36), or a negative response from the Europol Data Protection Officer to your complaint. Advisory opinions or internal recommendations don’t count. The decision must be concrete, binding, and alter your rights in a measurable way.
Which Types of Europol Actions Can Actually Be Challenged Before the CJEU?
Three boxes must all be checked before your case survives the admissibility stage. The contested measure must be an actionable decision (not a guideline or opinion). You must have legal standing—meaning the decision directly and individually concerns you. And you must file within two months of the day you learned of it.
Europol decisions most frequently challenged: data-processing determinations, access request denials, refusals to erase or correct data, and decisions on third-country cooperation that affect your privacy rights.
Here’s where many applicants stumble: challenging the Europol Regulation itself is nearly impossible. Case T-578/22 makes this plain. On 6 September 2023, the General Court rejected the European Data Protection Supervisor’s attempt to annul Articles 74a and 74b of the updated regulation. The court held that only individuals or organisations directly harmed—not EU institutions—can challenge legislative text. You need a specific Europol decision about *your* data, not a challenge to the law that governs Europol generally.
What is the two-month deadline for filing an action for annulment against Europol?
Article 263(6) TFEU sets a hard two-month clock. It starts on publication in the Official Journal, notification to you, or—if neither happens—the day you reasonably became aware. Add ten days if you live outside Luxembourg.
The General Court does not extend this period. Not for ignorance of the law. Not for bad legal advice. Not unless force majeure (war, natural disaster) physically prevented you from filing. Once two months pass, your case is inadmissible and the decision stands unchallenged forever.

Do you need a lawyer to sue Europol at the CJEU?
Yes. Article 19 of the Statute requires it. Parties before the General Court must have a lawyer admitted to an EU Member State bar. Self-representation results in automatic dismissal for inadmissibility. The rule exists to ensure pleadings meet procedural standards and that applicants grasp the legal and factual depth of EU institutional proceedings—but it also means if you can’t afford or find qualified counsel, you cannot proceed.
What is the cost of bringing a case against Europol to the Court of Justice?
Court filing itself costs nothing for individuals; legal entities face a nominal charge. Legal fees are the main driver—typically several thousand to tens of thousands of euros depending on the complexity, number of written submissions, hearing preparation, and expert evidence. Success matters financially: if you win, you can recover costs from Europol under Article 134 of the Rules of Procedure. Lose, and you may pay Europol’s legal costs on top of your own.
Frequently Asked Questions
Can individuals sue Europol directly at the CJEU, or only organisations?
Both. Article 263(4) TFEU allows natural persons and organisations to challenge Europol directly at the General Court—provided the contested act is addressed to you or it’s a regulatory act not requiring implementing measures that affects you directly. Individual applicants have succeeded against Europol’s data-processing decisions, access refusals, and cooperation agreements. Cases T-1180/23 and T-167/24, as well as the 2025 Kočner v. Europol judgment, illustrate this.
What happens if you miss the two-month deadline to file an action for annulment?
Your case is dead. Article 263(6) TFEU imposes a strict two-month limitation from notification of the act. The General Court applies it inflexibly; force majeure might buy you an extension, but that’s rare. Once it expires, the contested act becomes final. You cannot refile the same claim. Your only fallback is a damages action under Article 340 TFEU if you can prove Europol’s unlawful conduct caused you financial loss—but that’s a harder road and won’t void the original act.
Can you get interim relief or suspension of Europol’s decision while your case is pending?
Yes. Articles 278 and 279 TFEU allow you to request interim measures—typically suspension of the contested act. The President of the General Court grants them only if you show: (1) urgency, meaning serious and irreparable harm without relief; (2) a serious argument on the merits; and (3) that interests balance in your favour. Decisions come within weeks. If granted, the suspension stays in place until final judgment.
Does a CJEU judgment against Europol set a binding precedent for future cases?
The judgment binds Europol and the parties directly. Within the EU legal system—which doesn’t use formal precedent like common-law courts—CJEU decisions carry overwhelming authority. National courts and EU institutions follow them, and later applicants cite them extensively. The 2025 Kočner v. Europol damages award has become a reference for compensation claims in data-protection cases against Europol and similar agencies.
Can you appeal a CJEU judgment in an Europol case to a higher court?
You may appeal a General Court judgment to the Court of Justice within two months, but only on legal grounds—not facts. The higher Court will not re-examine evidence or second-guess the lower Court’s factual findings. If the Court of Justice dismisses your appeal, that decision is final within the EU system. In rare cases involving Convention rights, the European Court of Human Rights might review, but that’s a different track and not a straightforward appeal.
What is the difference between Article 263 TFEU review and a preliminary reference on Europol’s lawfulness?
Article 263 review is a direct action you file against a specific Europol act, seeking annulment. A preliminary reference under Article 267 TFEU is different: a national court asks the Court of Justice for guidance on EU law or the validity of an EU act in the context of national proceedings. Preliminary references don’t annul or award damages; they provide binding interpretive guidance the national court then applies. In Europol cases, preliminary references might arise when a national court reviewing extradition or criminal charges questions the validity of data Europol supplied.
