Dublin: The legal architecture of Europe’s flagship competition rulebook absorbed its first serious judicial blow on 3 June, when the General Court of the European Union annulled the European Commission’s decision to designate Meta’s Marketplace service as a gatekeeper under the Digital Markets Act. The ruling does not dismantle the regulation, but it punctures the assumption that the Commission’s designations would sail through the courts unexamined, and it forces a more rigorous conversation about where the law’s boundaries actually lie.
The Digital Markets Act works by naming a small number of very large platforms as gatekeepers and then binding them to a list of obligations and prohibitions intended to keep digital markets contestable. Designation is therefore the hinge on which the entire mechanism turns; without it, none of the substantive duties apply. The Commission had placed Marketplace, the classified-advertising feature embedded inside the social network, among the core platform services it judged to meet the law’s thresholds. The court found that reasoning wanting, and in annulling the designation it signalled that the quantitative gateways and qualitative assessments the regulation prescribes must be applied with more care than a presumption of inclusion.
For the company, headquartered for European purposes in Dublin, the immediate effect is relief from a specific set of obligations attached to that one service. The wider significance is precedential. Gatekeeper designations have been treated, in practice, as administrative determinations that platforms could contest but rarely overturn. A successful annulment establishes that the General Court will scrutinise the Commission’s market definitions and its reading of user metrics, and that the burden of demonstrating a service genuinely functions as an unavoidable gateway between businesses and consumers rests with the regulator, not merely with the regulated.
There is a candid limit to how far the judgment should be read. Annulling a single designation is not the same as weakening the Digital Markets Act as a whole, and the Commission retains the option to revisit Marketplace with a reinforced evidentiary basis or to appeal to the Court of Justice. The other designations that anchor the regime remain intact, and the substantive obligations on the platforms that clearly qualify are untouched. What the ruling does is raise the analytical bar, requiring that each contested service be measured against the statute’s criteria rather than swept in by association with a parent company that plainly is a gatekeeper elsewhere.
The deeper tension the case exposes is between speed and rigour. The Digital Markets Act was designed to act faster than traditional antitrust enforcement, which can take the better part of a decade to reach a remedy. Speed, however, is purchased by relying on bright-line rules and presumptions, and bright lines invite litigation precisely because they can sweep in cases that do not fit. The General Court has now reminded the Commission that procedural velocity does not excuse analytical shortcuts, and that the legitimacy of a novel regime depends on its decisions surviving exactly this kind of review.
The constructive reading is that judicial correction is a feature of a maturing legal order, not a failure of it. A regulation this consequential benefits from having its edges tested early, while the body of decisions is still small enough to adjust. The Commission emerges with a clearer sense of the evidence its designations must carry, the platforms with a clearer sense of their right to contest them, and the law itself with a sharper definition of what it means to hold the keys to a digital gateway. The rulebook stands; it now stands on firmer ground.
