The first round ended with Washington’s intervention and London quietly dropping the demand. The second round is narrower, quieter, and now on a tribunal calendar: Apple filed a fresh complaint in July challenging a revised British government order for access to the encrypted iCloud backups of UK users, and the Investigatory Powers Tribunal has scheduled a case management hearing for September.
The dispute turns on a tool called Advanced Data Protection, the optional setting that extends end-to-end encryption to iCloud backups, photos, notes, and other data categories. With it enabled, Apple does not hold the keys and cannot read the contents, even under legal compulsion. That is precisely what makes the government’s demand awkward: complying would mean weakening or redesigning the service rather than simply turning over files.
The current fight has its roots in the opening months of 2025, when the UK secretly issued a technical capability notice under the Investigatory Powers Act ordering Apple to provide access to ADP-protected backups. A technical capability notice is a classified order that can compel a company to build the technical means for law enforcement to reach data, encryption notwithstanding. Apple responded by pulling Advanced Data Protection from UK customers and contesting the order before the same tribunal. After pressure from the Trump administration, which argued the demand may have breached a bilateral privacy agreement, the UK withdrew the original notice in August 2025, only to issue a replacement two months later that applied to British accounts rather than American ones.
That replacement is what Apple now challenges. The company’s complaint, filed in July, contests the government’s powers to issue technical capability notices at all, according to details carried by the Financial Times. Because notices are subject to statutory secrecy, the substance of Apple’s arguments is not public. Neither the company nor the Home Office may discuss the matter, and neither responded to requests for comment.
The tribunal notified Privacy International, the human rights group, of the new complaint. That organization, together with the campaign group Liberty, already runs a parallel case at the tribunal challenging technical capability notices, and their earlier submissions asked for Apple’s claims to be heard in open session because the matter carries clear public interest, while questioning whether the reported notice was lawful, necessary, and appropriately secret, and whether the legal regime behind such notices is defensible at all. A case management hearing next month will decide how the two complaints proceed together. The tribunal has not indicated when it will rule.
Apple’s public position has been consistent through both rounds: it says it has never installed, and never will install, a mechanism that bypasses its own encryption, arguing that any such capability would weaken security for every customer, not just those under the order. When it removed Advanced Data Protection from the UK market last year, it said the move left British customers more exposed to data breaches.
The stakes extend beyond one company. If the UK compels Apple to weaken encryption, the same legal playbook becomes available to other governments, and privacy groups argue the outcome will set a precedent for how far states can push against end-to-end encryption. The September hearing is the first public milestone in a fight that has already outlasted one government demand and is now testing a second.
