The Wikimedia Foundation has lost its legal challenge against the Online Safety Act's categorization regulations, depriving it of immediate legal protections it wanted.

The High Court of Justice in London has dismissed a legal challenge presented by the Wikimedia Foundation in regards to the UK’s Online Safety Act (OSA) Categorization Regulations. This decision by the court means that Wikipedia doesn’t have the immediate legal protections that it had hoped for.

The Wikimedia Foundation’s challenge targeted regulations that risk imposing the OSA’s most stringent obligation (Category 1 duties) on Wikipedia. This case was notable as it was the first legal challenge against the OSA’s Categorization Regulations; however, the dismissal is a significant setback for the foundation’s proactive legal strategy.
