Meta and TikTok lose High Court battle against Ofcom data demands

• The High Court has upheld Ofcom's powers to demand retroactive safety data from tech giants under the Online Safety Act. • Meta, TikTok and X jointly challenged formal information notices issued in February, arguing Ofcom circumvented the act's transparency framework. • The court refused permission for the claims in the first judicial review to test Ofcom's new powers, which include fines of up to £18m or 10 per cent of global turnover.
