Apple is back in court against the UK government. The company filed a legal challenge at the Investigatory Powers Tribunal against a new Technical Capability Notice issued by the Home Office, which demands backdoor access to encrypted iCloud backups belonging to British users.
What the UK wants, and what Apple won’t give
The Technical Capability Notice, or TCN, is essentially a legal order from the UK’s Home Office compelling Apple to build a backdoor into its Advanced Data Protection feature. ADP is Apple’s end-to-end encryption system for iCloud backups, meaning only the user holds the keys to their data. Not Apple, not the government, not anyone else.
Apple has stated plainly that it has never built a backdoor or master key to its products and services, and never will. That’s a legal position the company is prepared to defend in court, again.
The original TCN was issued in January 2025, and Apple’s initial response was to disable Advanced Data Protection for UK users entirely. The broader global access demand that accompanied that first TCN was eventually withdrawn in August 2025, reportedly due to diplomatic pressure from the US. The Home Office then issued a revised, UK-specific TCN, and that’s the order Apple is now challenging. Apple filed its legal challenge at the IPT in July 2026.
