EU's supreme court, seated in Luxembourg; rules on EU law and member state compliance.

Background

The Court of Justice of the European Union is the EU's highest judicial body, seated in Luxembourg. It operates in two tiers: the Court of Justice, with 27 judges, one per member state, and the General Court, with 54 judges, which handles first-instance competition, state-aid and trade cases. It traces its origin to 1952, as the Court of Justice of the European Coal and Steel Community.

Its core functions are to ensure uniform application of EU law through preliminary rulings under Article 267 TFEU, infringement actions brought by the Commission, and challenges to the validity of EU acts. It grants interim relief, suspending an EU act pending full annulment proceedings, only where an applicant demonstrates urgency and a real risk of serious and irreparable harm; that threshold is deliberately high, and most suspension bids fail at the interim stage.

That structure makes the court an active enforcement lever across the full landscape of EU law, from sanctions and trade disputes to competition rulings and constitutional questions about voting thresholds in the Council, rather than a body confined to any single policy area.

Key Issues
Gas ban litigation

Slovakia stands alone against the ban

Viktor Orban's government filed the original February 2026 challenge to Regulation 2026/261, arguing the Russian pipeline gas ban needed unanimous Council approval as a sanction rather than a majority-vote trade act. Peter Magyar's Tisza government took office in May 2026 and withdrew the interim relief application, ending the dual-state pressure Budapest and Bratislava had built .

Robert Fico's government pressed on with Slovakia's own annulment claim after Hungary's withdrawal, but the court refused it an interim stay on 17-18 June 2026, and the ban bound on 17 June with no judicial relief granted. Fico's annulment case now proceeds on the merits alone, a track that runs for years while the ban already applies .

Competition rulings

Court dismisses an eight-year appeal

The Court of Justice dismissed a final appeal on 2 July 2026, confirming a EUR 4.1bn fine imposed over Android licensing practices dating to 2018. The ruling closes an eight-year case that tested how FAR a dominant platform's contractual bundling can go under EU competition law .

The dismissal lands as Brussels weighs a separate, more recent fine against the same company under newer EU digital-platform rules, illustrating how the court's competition docket and its digital-markets docket can run in parallel against the same defendant on different legal grounds.

Common Questions
What is the CJEU and how does it differ from the European Court of Human Rights?
The CJEU is the EU's own supreme court, seated in Luxembourg, and interprets EU law binding on all 27 member states. The European Court of Human Rights is a separate Council of Europe body (not an EU institution) covering 46 countries under the ECHR.
Can Hungary's CJEU challenge stop the EU Russian gas ban?
Hungary filed its challenge in February 2026 arguing the ban required unanimous approval as a sanction. No preliminary injunction has been issued, so the ban remains in force. A full ruling could take 18-24 months; the Commission's TurkStream derogation Deadline of 5 August 2026 arrives first.Source: Lowdown european-energy-markets briefing
How long does a CJEU infringement case take?
Infringement proceedings typically take 2-4 years from Commission letter to final judgment if a member state refuses to comply. Urgent cases with an interim measures application can be decided more quickly, but none has been sought in the Hungary gas ban challenge.
Which EU member states face CJEU referral for missing energy law deadlines?
Croatia, Poland, and Portugal received reasoned opinions in April 2026 for failing to transpose Directive 2024/1711 on consumer gas prices by the January 2025 Deadline, putting them one step from a formal CJEU referral and potential daily fines.Source: European Commission, April 2026 infringements package
Did the CJEU block the EU gas ban before it took effect?
No. The CJEU did not grant an interim stay to Slovakia. Regulation (EU) 2026/261's short-term pipeline import ban bound on 17 June 2026 without judicial relief. The substantive annulment case continues on a multi-year track.Source: European Energy Markets Update 19
Why is it hard to get an emergency suspension from the CJEU?
Interim relief from the CJEU requires the applicant to demonstrate urgency and the real risk of serious and irreparable harm. The bar is deliberately high; most suspension applications fail at the interim stage even when the underlying annulment case has merit.Source: CJEU procedural rules (Art. 160 Rules of Procedure)
