Apple has filed a legal challenge against the UK government over a Technical Capability Notice (TCN) that would force the company to give law enforcement access to encrypted iCloud backups belonging to British users. The case, working its way through the Investigatory Powers Tribunal (IPT), is shaping up to be one of the most consequential privacy battles in recent memory.
The encryption tug-of-war
The original TCN, issued in January 2025, demanded access to iCloud data on a worldwide basis, not just for British citizens. That order was reportedly withdrawn after pressure from the US government. A second, more narrowly targeted TCN was issued around September or October 2025, this time focusing specifically on iCloud user data within Britain.
Apple had rolled out its Advanced Data Protection (ADP) feature for UK users in 2024, giving them end-to-end encryption on their iCloud backups. In early 2025, in response to the first TCN, Apple withdrew that feature for UK users entirely rather than build a backdoor into it.
