EU court upholds €68.5 million Turow fines, rejects Poland appeal

The Court of Justice of the European Union on Jan. 22, 2026 dismissed Poland’s last legal challenge to periodic penalty payments imposed over Warsaw’s failure to suspend operations at the Turów lignite mine, affirming the lawfulness of the recovery of roughly €68.5 million from Poland’s EU budget disbursements. The ruling concludes a multi-year enforcement saga that began with an interim order in May 2021 and centered on cross-border environmental harm and compliance with EU law.

The dispute began after the Czech Republic initiated proceedings in 2021, arguing that Poland’s expansion of mining at the Turów open-cast site near the Czech and German borders risked transboundary environmental damage. A Vice-President of the CJEU ordered Poland on May 21, 2021 to cease mining activities as an interim measure. Poland did not comply, and the court imposed a periodic penalty payment reported at €500,000 per day. Those penalties accumulated until the amounts were recovered.

Poland and Czechia later reached a bilateral settlement that removed the case from the court’s register. Poland argued that the settlement should retroactively extinguish the penalty amounts that had already accrued. The General Court rejected that position in 2024, concluding that removal of the case from the register did not erase obligations that had already fallen due.

Poland appealed to the CJEU in Case C-554/24 P seeking annulment of the daily penalties. The court dismissed the appeal and reiterated a core legal principle: "the actions of the parties to the dispute, including the conclusion of a settlement agreement, cannot have the effect of retroactively varying, annulling or setting aside an order imposing such a periodic penalty payment." The judgment added that the settlement "could not therefore extinguish Poland’s obligation to pay the periodic penalty payments that had already fallen due," confirming the Commission’s deductions from Poland’s EU payments as lawful.

The decision has immediate fiscal and legal consequences. The recovered sum of about €68.5 million represents roughly 137 days of penalties at €500,000 per day, providing a to-the-point illustration of the cost of non-compliance with interim court orders. More broadly, the ruling cements the European Commission’s authority to enforce compliance through financial recovery from EU funds when member states fail to meet court-mandated obligations.

The outcome also tightens legal clarity for future cross-border environmental enforcement. By closing the question of whether private or bilateral settlements can erase amounts already adjudicated by EU courts, the decision reduces a potential avenue for states to neutralize interim enforcement measures through later agreements.

Energy security arguments featured throughout the litigation. Polish officials had defended continued mining on grounds that the adjoining power plant supplied approximately 7 percent of the country’s electricity, underscoring the domestic trade-offs between short-term energy supply and compliance with EU environmental norms. The ruling forces policymakers in member states to reconcile those trade-offs with the reality of robust enforcement mechanisms at the EU level.

With the ECJ’s dismissal, the enforcement phase of the Turów dispute is effectively closed. The judgment establishes a precedent reinforcing the finality of court-imposed penalties and the Commission’s toolkit for ensuring compliance across the single market.
