The High Court of Justice of Madrid refused on 23 March 2026 to suspend the €64 million fine imposed on Airbnb by Spain's Ministry of Consumer Affairs, allowing enforcement to proceed while the substantive appeal continues 1. The fine was issued in December 2025 for unlicensed listings, falsified registration numbers and misleading advertising. The procedural question the court answered was narrow. The precedent it set is not.
Every platform challenge to national short-term rental (STR) rules in the EU since 2019 has ended with the platform winning at some stage of the appeal chain. The Madrid ruling resets the reference price of non-compliance from notional to a real nine-figure euro number that a named platform is, for now, being made to carry. Other member states are watching. Germany has not yet transposed the underlying EU rules. France, Italy and the Netherlands have transposition in various stages of readiness but no test case of this scale.
Spain's legal basis for the fine is Royal Decree 1312/2024, the national implementing act for EU Regulation 2024/1028, the bloc-wide STR registration regulation that takes full effect on 20 May 2026 2. The royal decree came into force on 2 July 2025. The conduct the ministry sanctioned predates full implementation, which gives Airbnb a procedural opening on temporal grounds. The platform's substantive argument, advanced by its lawyers in off-record briefings to Spanish media, is that consumer-affairs ministries cannot use national STR rules to impose what amounts to prior authorisation on a cross-border digital service. That is the EU information-society-service doctrine, and it is the same argument that has won Airbnb and Uber cases at the Court of Justice since 2019.
The counter-reading, which Spain's Ministry of Consumer Affairs is relying on, is that the fine concerns the accuracy of what Airbnb was listing rather than whether it could operate in the Spanish market at all. That distinction has been accepted by the Court of Justice in narrow cases but not as a general principle. If the Madrid court accepts Spain's framing at substantive hearing, the €64m becomes a live precedent for every national regulator looking at the 20 May deadline. If it does not, the fine becomes a political embarrassment, and EU-wide enforcement reverts to a mechanism that does not yet exist at scale. Spain's enforcement action connects directly to the wider platform-regulation settlement tracked in .
