Apple is launching a new legal challenge in response to a UK government effort to obtain access to encrypted user data, according to reports from the Financial Times, Bloomberg and Channel NewsAsia. The latest dispute follows another round of government demands that Apple says would require it to connect to or provide access to data stored in the cloud, including backups associated with British users.

The Financial Times reports that Apple files a complaint over an additional request aimed at getting access to encrypted information, specifically referencing cloud backups of UK users. Bloomberg, citing two people familiar with the matter, says Apple is again contesting the UK’s attempts to reach customers’ files that are protected by encryption. The reports indicate Apple is approaching the matter through court action, continuing its longstanding legal position that any requirement to assist with access to encrypted data would undermine security.

The outlets do not provide details on the UK government’s specific legal basis or the procedural status of the case. Overall, all reports describe the same core development: Apple continues to challenge UK demands related to encrypted data access, including through cloud-backed information.
