Bilbao: The Spain state liability case is heading back to the Court of Justice of the European Union after the European Commission concluded that Madrid has not carried out a judgment the Court delivered on 28 June 2022. The Commission announced the step in its October 2026 infringement package, published on 1 October. It describes a bill that is still pending in the Spanish Parliament and a ruling that has not yet changed national law.

The history of the Spain state liability case shows how slowly some cases move. The Commission sent a letter of formal notice to Spain in June 2017 and a reasoned opinion in January 2018. It referred the country to the Court in November 2019, and the judges delivered their ruling in June 2022. The Commission then sent a further letter of formal notice in December 2025 after it concluded that Spain still had not complied.

At stake is a basic principle of the Union legal order. When a member state breaches EU law, individuals and businesses that suffer harm can claim compensation before national courts, and national rules must not make that right impossible or excessively difficult to use. The Court’s 2022 ruling found that Spain fell short of the principles of equivalence and effectiveness, and the Commission now says that Spain has not made the corrections that the judgment demands.

The Spain state liability case matters well beyond Spanish courtrooms. State liability is one of the few remedies that private parties can invoke when legislators themselves break EU rules, and the strength of that remedy depends on national procedure. If one large member state keeps rules that limit access to compensation, companies and citizens in other countries watch whether the Union tolerates the gap.

A second referral raises the stakes for Madrid because the Treaty gives the Commission a stronger tool when a country ignores a judgment. Article 260 of the Treaty on the Functioning of the European Union allows the Court to impose a lump sum or a daily penalty on a member state that fails to comply with an earlier ruling. The Commission’s published summary does not set out the amounts it seeks, so the financial exposure remains open.

Spain’s government can still end the Spain state liability case by finishing its legislation. The bill that sits before the Cortes Generales would change the rules on liability claims, and the pending text gives ministers a clear route to closing the file. The question is whether lawmakers act before the Court schedules a hearing, because a parliamentary vote after a referral does not automatically end the proceedings.

Lawyers who handle compensation claims against the state will follow the Spain state liability case closely. Many national systems still require claimants to clear procedural hurdles that the Court of Justice treats with suspicion, and each new ruling clarifies how far governments can go in shaping those hurdles. A decision against Spain would send a warning to other capitals that keep similar rules.

For now, the Spain state liability case remains in the procedural stage, and neither side has published a timetable for the hearing. The Commission has made its position plain: a judgment of the Union’s highest court binds Spain, and a bill that sits in Parliament for years does not meet that duty. The Spain state liability case will show how firmly Luxembourg enforces its own rulings.
