PARIS — For every French teenager who spent the past year watching Parliament debate whether to lock them off TikTok, Instagram, and Snapchat until they turned 15, the answer arrived on Thursday from the country’s highest legal body: not yet, and not like this.
France’s Constitutional Council struck down legislation that would have made France the first European country to ban social media access for anyone under 15. The ruling did not dispute that governments have an interest in protecting children online. What it found, instead, was that the bill as written had never solved the problem that sits at the centre of any such ban.
To enforce a minimum age on a platform, the platform must verify the age of everyone using it, including adults. The court was precise in identifying why this matters: “By prohibiting minors under the age of fifteen from accessing certain online services, the law inherently requires every person, even an adult, to prove their age before accessing them.” Parliament, the council said, had “failed to specify the conditions and limits under which such proof must be provided,” leaving no legal framework for a system that would, in practice, restrict the speech and privacy of the entire French adult population.
That is not a drafting oversight. It is a structural tension that any age-restriction system eventually arrives at: the mechanism capable of reliably identifying minors is, by definition, a mechanism that identifies everyone. Digital rights advocates in Paris had pointed to this conflict for two years. The Constitutional Council has now written it into law.
Australia handled the same problem differently. When Canberra passed the world’s first under-16 social media ban in December, it did so with explicit platform-liability provisions, a designated age-assurance regulator, and a technical framework specifying what verification systems were acceptable. France’s parliament wrote the ambition without the architecture, and the court found the gap fatal.
President Emmanuel Macron, constitutionally barred from seeking a third term and heading into a presidential election season that begins in spring 2027, ordered Prime Minister Sébastien Lecornu to rework the legislation and put revised rules in force before voters return to the polls. The political calendar is not incidental. A functioning social media protection bill would serve as a legacy marker for the Macronist political centre, which has faced sustained pressure from both left and right. A bill returned by the country’s highest court is a different kind of marker.
What Lecornu is being asked to rework is the hardest element of the original bill: the age-verification mechanism. The Constitutional Council’s ruling established that any new law must specify the technical conditions under which age proof is collected, the limits on what data platforms may retain, and the enforcement consequence for non-compliance. That is essentially asking Parliament to legislate the architecture of a privacy-preserving age-verification system that does not yet exist at commercial scale anywhere in Europe.
France is not alone in navigating this. The European Union’s own regulatory framework has been pushing platforms toward greater accountability at every level of the stack. The EU AI Act now requires AI providers to make their outputs technically traceable, placing disclosure obligations on companies that also rest on infrastructure the platforms must themselves build. The pattern holds across Brussels and Paris alike: both want platforms to be accountable for what happens on their services, and both keep discovering that accountability systems capable of addressing the harm also create surveillance architectures capable of enabling it.
The Constitutional Council left the door open explicitly. Its ruling stated that a revised law specifying the necessary technical conditions and privacy safeguards would not face the same constitutional objection. That is not a full endorsement; the court set no template. But it is an invitation.
In the meantime, French children under 15 remain able to create accounts on TikTok, Instagram, and Snapchat. The platforms are not currently required to take any additional protective action. France’s data protection authority, the CNIL, which had been developing technical recommendations for age-assurance systems in anticipation of the law’s entry into force, must now hold its guidance while the legislative process begins again.
Whether revised legislation makes it through the National Assembly before the spring 2027 electoral cycle determines who replaces Macron is a question no one in Paris appears ready to answer with confidence. France has been attempting to legislate social media for minors since 2023, and the bill the Constitutional Council just struck down was the third version of an effort that predates Macron’s most recent term. According to TRT World, which first reported the ruling’s details, Macron committed publicly to having the reformed legislation in force before the election.
What the ruling tells platforms is both relieving and precise. No enforcement action is coming in France on this issue in the near term. But the constitutional logic the council applied, that age-gating at scale requires universal verification which then triggers constitutional review, will apply identically to any successor law. Platforms that anticipated eventually having to implement robust age-assurance systems have not been released from that expectation. They have simply been given more time while France’s government works out how to write the legal mandate in a form the court will accept.
That is the gap every democracy attempting to limit children’s access to social media has eventually fallen into: the goal is defensible, the technology is not yet mature, and the law keeps arriving before the infrastructure does.
