Meta, TikTok and X Lose Court Challenge to Ofcom Data Notices in UK First

The UK High Court has dismissed legal challenges from Meta, TikTok and X against information notices issued by Ofcom, in the first court test of the regulator's data gathering powers under the Online Safety Act 2023. The Divisional Court ruled that the notices were lawful, in a decision reported on 2 November 2026. The case concerned notices sent to TikTok, X and Meta's WhatsApp service in February 2026, after months of discussion between Ofcom and the companies. For people in the UK, the ruling does not change how any app works overnight. It does settle an important question about how much information Ofcom can demand when it checks whether large platforms are meeting their online safety duties.

What the court decided

The court rejected arguments that the notices went beyond Ofcom's powers, were disproportionate, or were made for an improper purpose. Reporting says the court found most arguments unarguable in law or on the facts. On proportionality, the judges weighed Ofcom's aims, the relevance of the material, and the practical effect on the companies, and rejected that challenge too. The companies had not shown enough evidence about baselines or resource impact. The notices stand, and the companies must now comply.

The ruling is reported as case R (Meta Platforms and others) v Ofcom, citation [2026] EWHC 2779 (Admin), with Lord Justice Singh and Mrs Justice Collins Rice named as the judges. Because this was a judicial review, the court tested whether Ofcom acted lawfully in issuing the notices, rather than deciding whether any platform broke safety rules. A win for Ofcom here does not mean any company harmed users. It means the regulator's evidence gathering tool survived its first legal challenge.

What Ofcom asked for

Ofcom's notices asked for detailed information about how the platforms run content moderation. The requests covered the definitions each company uses for actions such as removals, restrictions and warnings. They also covered user activity broken down by age group, and the volumes, timelines and outcomes of moderation decisions. A further part of the request covered how UK users were exposed to material that had been actioned, along with appeals and reports submitted by users in the UK.

The point of that detail is to make oversight checkable. Without numbers on what was removed, when, and after how many reports, a regulator cannot test a claim of fast action. Age breakdowns matter because the Act emphasises protecting children. Exposure data shows how many people saw a post before it came down, and appeals data shows whether users have a realistic route to challenge a decision. Ofcom issued the notices under section 100 of the Act, which lets it require information to carry out its safety functions, provided it acts proportionately. That proportionality test became central to the case.

Why the companies challenged the notices

Meta, TikTok and X argued that the notices exceeded Ofcom's statutory powers and were disproportionate. They also argued that the notices served an improper purpose, that Ofcom had effectively decided the outcome in advance, and that the regulator had failed to carry out impact assessments or follow its own published policies. Those are standard grounds in judicial review cases, where a claimant asks a court to quash a public body's decision.

The court dismissed those arguments, finding them unarguable apart from proportionality. On proportionality, it weighed the regulator's aims against the burden on the companies and concluded that no notice was shown to be unfair or disproportionate. The claimants, the court said, did not sufficiently identify baselines or differential resource impact. In plain terms, they did not show compliance would impose an unreasonable extra burden.

Why this ruling matters for UK users

For ordinary users, the effect is indirect. Ofcom can now use the data to judge whether platforms meet their duties and to spot patterns that public statements might hide. High appeal success rates could point to over removal, slow handling of UK reports could point to weak processes, and high exposure among younger users could raise questions about age appropriate protections. None of those findings are in this judgment, which is about the power to ask, not about what the answers show.

The ruling also strengthens Ofcom's hand in future discussions with platforms, and may reduce appetite for similar challenges. It does not give Ofcom unlimited power. Any future notice must still be relevant, proportionate, and tied to a safety function. Much of the data will not be published in full, because it can include commercially sensitive detail. What users may see, over time, is firmer action or clearer public reporting based on those numbers.

What happens next

The notices are now legally in force, and the platforms named are obliged to comply. Next comes compliance: producing the data as requested, and answering follow up questions if Ofcom finds gaps. Failure to comply can lead to enforcement, with serious breaches attracting large fines. Reporting notes that fines under the Act can reach up to 10 percent of qualifying worldwide revenue or 18 million pounds, whichever is greater, although that ceiling applies to serious breaches and not to every failure.

For the platforms, the options now are to comply, to seek to narrow a request through engagement with Ofcom, or to challenge a future notice on its own facts. For Ofcom, the ruling removes a legal cloud over a main evidence tool. For users, the sensible expectation is not a sudden change in any app, but a regulator better able to check safety claims with real data. The case was about whether the regulator can ask the questions, and the court has said that it can.

Frequently Asked Questions

What did the court actually decide in the Ofcom case?

The court dismissed challenges from Meta, TikTok and X against Ofcom information notices under the Online Safety Act 2023. It found the notices lawful, rejecting claims they exceeded Ofcom's powers, were disproportionate, or served an improper purpose. The notices are now in force.

What information did Ofcom ask the platforms to provide?

Ofcom asked for definitions used for moderation actions, user activity by age group, and the volumes, timelines and outcomes of content moderation. It also asked about UK users' exposure to actioned material, and about appeals and reports submitted by users in the UK.

Does this ruling change how Meta, TikTok, X or WhatsApp work in the UK?

No, not directly. The ruling concerns Ofcom's power to gather evidence, not a finding that any platform broke safety rules. Change would come later, if Ofcom uses the data for enforcement or published findings.
