A single supermarket chain’s fight over price tags has produced one of the most consequential internal-market rulings of the year. The Court of Justice of the European Union has found that a Hungarian scheme forcing large food retailers to slash prices on selected goods breaches EU law, handing a defeat to a government that had cast the measure as consumer protection and a win to companies that argued it was an unlawful intrusion into how they run their business.
The dispute traces back to May 2023, when food inflation was still biting across much of the bloc. Budapest introduced mandatory promotional periods under which retailers above a certain turnover threshold had to sell listed products at least fifteen percent below the lowest price they had charged in the previous thirty days. Non-compliance carried fines. The government presented the rule as a shield for shoppers squeezed by rising grocery bills. Penny Market, one of the chains caught by the scheme, challenged the penalties and the case, C-658/24, worked its way up to the Luxembourg bench.
The judges were unpersuaded that the design matched the stated purpose. Their reasoning turned on the Services Directive, the instrument meant to guarantee that companies can compete across the single market without arbitrary national barriers. Forcing traders to price particular goods below a self-referential benchmark, the Court held, strips them of the freedom to set prices and volumes according to ordinary commercial judgment. That is a restriction, and a restriction can only survive if it is justified and proportionate.
On proportionality the scheme failed. The Court noted that the measure did not pursue its anti-inflation aim in a consistent or systematic way, targeting some products and some sellers while leaving others untouched, which undercut any claim that it was genuinely calibrated to protect consumers. A rule that bites unevenly looks less like a coherent policy and more like a blunt instrument, and blunt instruments rarely clear the bar EU law sets for interfering with commercial freedom.
The ruling matters well beyond one chain and one member state. Governments across the Union have reached for price controls, windfall levies and mandatory discounts during successive cost-of-living shocks, often under intense domestic pressure to be seen doing something. The judgment is a reminder that popular measures still have to respect the architecture of the single market, and that emergency framing does not suspend the proportionality test. Retail associations will read it as confirmation that Union law constrains how far national capitals can go in dictating shelf prices.
For the Hungarian government the timing is awkward. The Commission has separately moved to refer the country to the same court over its retail tax regime, arguing that the turnover-based levy discriminates against larger, often foreign-owned, chains. Taken together, the two files sketch a broader tension between a government keen to lean on big retailers and an EU legal order that treats such targeting with suspicion.
None of this settles the underlying question that made the discount scheme politically attractive: how to protect households when food prices spike. The Court did not say governments are powerless, only that whatever they do must be coherent, justified and applied without unwarranted discrimination. Critics of the ruling will argue it privileges corporate pricing freedom over vulnerable shoppers. Defenders will counter that predictable, market-wide rules serve consumers better in the long run than improvised interventions that distort competition. That debate will outlast this case, but retailers now have a precedent to point to the next time a capital reaches for the price-tag lever.
