US lawmakers Ron Wyden and Warren Davidson are urging Britain's investigatory powers tribunal to increase transparency in Apple's legal challenge against a UK government demand to break encrypted iCloud backups. The dispute stems from January 2025 when the Home Office issued a technical capability notice requiring Apple to assist law enforcement, prompting Apple to withdraw its Advanced Data Protection feature from UK users. The American politicians argue the UK is improperly using secrecy directives to circumvent US Congressional oversight and constitutional powers.
