What the High Court Ruling Means for Meta, TikTok and X Under the Online Safety Act

Meta, TikTok and X must hand over detailed content-moderation data to Ofcom after the High Court dismissed their legal challenge on 30 October 2026.

A Divisional Court at London's High Court, sitting as Lord Justice Singh and Mrs Justice Collins Rice, refused to quash the information notices Ofcom issued in February 2026. The court rejected the platforms' arguments that the demands were unlawful, disproportionate or irrational. This was the first judicial review to test Ofcom's information-gathering powers under the Online Safety Act 2023.

The notices require the companies to report the number of posts removed or restricted in visibility, the number of users exposed to harmful content, user activity broken down by age group, and how they moderate harmful content seen by children. Those categories are now concrete reporting obligations, not broad regulatory requests.

For the platforms, the ruling means building or adapting data pipelines, audit logs and reporting dashboards to answer Ofcom's requests. That is an engineering and compliance burden as much as a legal one, and it now carries judicial backing.

The decision strengthens Ofcom's ability to compel granular moderation data from major platforms and sets an early precedent for how the UK's online safety framework will be enforced. It lands amid political tension over UK online regulation and free speech, with criticism of the country's approach coming from US President Donald Trump and Elon Musk.

What the ruling does not do is resolve every question. The specific metrics and formats the platforms must report, and on what timeline, have not been set out in the judgment. Whether Meta, TikTok or X will appeal is not yet known.

What is clear is that the first court test of Ofcom's information powers went the regulator's way. The notices stand, and the three platforms must now produce the data they sought to avoid.
