Apple is challenging a secret UK Home Office directive that mandates a backdoor for encrypted iPhone and iCloud data. The government issued this Technical Capability Notice under the Investigatory Powers Act for national security and law enforcement purposes.

Apple argues that weakening encryption compromises security for its global user base and violates core privacy commitments. Human rights groups Liberty and Privacy International have joined Apple in the legal challenge at the Investigatory Powers Tribunal.

The lawsuit seeks to force the UK government to publicly acknowledge the order. Apple describes the current secrecy as farcical and claims it prevents public debate on matters of significant public interest.
