France's court knocks back an under-15 social media ban. What does it mean for Australia?
For anyone watching how democracies are trying to wrestle Big Tech under control, the past fortnight in Paris has been instructive. France's Constitutional Council — the country's highest legal authority on the compatibility of laws with the constitution — has blocked a bill that would have banned children under 15 from using social media platforms without parental consent. The rejection is a blow to President Emmanuel Macron, who has spent much of the past two years arguing that unchecked platform access is harming a generation of French children.
It also lands at an awkward moment for Australia, which is pushing ahead with its own, even stricter under-16 ban. If a country as regulation-friendly as France can't get a youth social media law past its own judges, what does that tell us about the wave of similar proposals crashing across the democratic world?
What the French court actually decided
The bill, backed by Macron and passed by the French parliament earlier this year, would have required social media platforms to verify users' ages and block anyone under 15 unless a parent or guardian gave permission. According to reporting by The Guardian, Reuters, CNN and The Canberra Times, the Constitutional Council struck the law down before it could take effect.
The Council did not rule that protecting children online was unimportant — quite the opposite. Its objection was procedural and constitutional: the law, as drafted, raised concerns about free expression, the right to information, and how far the French state can go in restricting adults' and minors' access to online services without running afoul of European Union rules that govern digital services across the bloc.
In other words, France may still get an under-15 ban. But the version that emerges will have to be redrafted, likely coordinated with Brussels, and much more carefully justified against competing rights. That's not a small hurdle.
Why governments keep reaching for age limits
The political appeal of an age-based ban is obvious. Parents are anxious. Teachers report shorter attention spans and worsening mental health. High-profile testimony from former tech employees and a steady drumbeat of research linking heavy platform use to anxiety, sleep disruption and body-image issues have pushed the conversation from parenting forums into parliaments.
Macron has been one of the loudest voices in Europe on this. He has publicly called for a Europe-wide minimum age of 15 for social media, framed screen time as a child-development issue on par with alcohol or tobacco, and threatened unilateral French action if Brussels didn't move. The bill that has just been struck down was, in effect, his attempt to force the issue.
Australia has gone even further. Canberra's legislation, passed last year, sets the age floor at 16 and puts the compliance obligation squarely on the platforms rather than on parents. It is one of the most aggressive youth-protection frameworks in the world, and other governments — from the UK to several US states — are watching closely to see whether it actually works.
The case for age limits
Advocates of hard age floors make three main arguments.
- Developmental harm. Adolescent brains are unusually sensitive to social feedback loops. Algorithmic feeds tuned to maximise engagement are, by design, well-suited to exploit that sensitivity.
- Market failure. Platforms have known about harms for years and have not meaningfully changed their products. Voluntary safety features, age gates and parental controls have consistently under-delivered.
- Parental support. A blanket legal age gives parents cover. It is much easier to say "no" to a 13-year-old when the answer is "it's the law" rather than a family-by-family negotiation.
There is also a symbolic argument. Democracies routinely set minimum ages for driving, drinking, voting and gambling. If social media is genuinely psychoactive — and the evidence increasingly suggests it can be — then treating it like any other regulated product is not a radical proposition.
The case against — which the French court just partly endorsed
The counter-arguments are exactly the ones the Constitutional Council appears to have weighed.
Free speech and access to information. Social media is not just entertainment; for many young people it is where news, political debate, LGBTQ+ community, activist organising and access to minority-language content actually happens. Cutting under-15s off wholesale is not a neutral act. It removes them from the public square.
Age verification is invasive. To enforce a ban, platforms need to know how old every user is — which in practice means collecting government ID, biometric scans, or credit-card checks from everyone, adults included. Privacy advocates have warned that we may end up building a surveillance apparatus around a child-protection law.
Enforcement is leaky. Determined teenagers use VPNs, borrow older siblings' logins, or migrate to smaller platforms that fly under regulators' radar. A ban that pushes kids from mainstream platforms with (however imperfect) safety teams to obscure corners of the internet may actually make them less safe.
It lets platforms off the hook. If the policy response is "kids shouldn't be there," the pressure to fix the underlying product design — the algorithms, the dark patterns, the ad targeting — eases. Some critics argue governments should be regulating the platforms' behaviour, not the users' age.
What the French ruling means for Australia
Australia's under-16 ban is on a different legal foundation than France's. We do not have a single written constitution containing an explicit free-expression clause; the implied freedom of political communication is narrower than the protections available under the European Convention on Human Rights, which shapes French law. That makes an Australian court less likely to strike down the ban on rights grounds alone.
But the French decision matters for us in three practical ways.
- It shows the debate isn't settled — even in Europe. Australian officials have sometimes framed the local ban as part of an inevitable global consensus. The Paris ruling is a reminder that serious jurists, in a country whose president is one of the loudest advocates of a ban, can find such laws legally defective.
- It puts pressure on the design of enforcement. If Australian age-assurance technology proves invasive, inaccurate or discriminatory, we can expect legal challenges of our own. The government's ongoing age-assurance trial will be critical.
- It complicates cross-border coordination. A patchwork of national laws — 15 in France (eventually), 16 in Australia, 13 in most of the US under existing federal law — makes compliance messy for platforms and creates lobbying openings to water everything down to the lowest common denominator.
A more honest conversation
The most useful thing about the French court's intervention is that it forces lawmakers to be specific. "Protect kids online" is a slogan. Specifying which harms, on which platforms, at which ages, using which enforcement tools, tested against which rights — that is policy.
Australia is about to find out whether its own bold framework survives contact with reality. Platforms will resist. Parents will demand exemptions. Teenagers will route around the rules. Courts, sooner or later, will be asked to weigh in.
The lesson from Paris isn't that age limits are wrong. It's that if you're going to restrict a fundamental communications tool for millions of young citizens, the law had better be tight, proportionate and honest about its trade-offs. Anything less, and you end up where Macron just did — with a defeated bill and a debate that has to start over.
