Apple has reportedly lodged a ‘first of its kind’ appeal to the Investigatory Powers Tribunal (IPT), an independent judicial body which oversees legal complaints made against public authorities or intelligence agencies in the UK if they commit a potentially unlawful action.

Apple has begun legal action to resist a secret demand by the U.K. government for access to iPhone users’ data. Citing “people familiar with the matter,” the Financial Times reports that the company has made an appeal to the Investigatory Powers Tribunal, seeking (likely on grounds of U.S. national security) to have the order quashed.

Apple told TechRepublic it is “gravely disappointed” to remove Advanced Data Protection in the U.K., as it fights government demands for an iCloud backdoor.

Apple is pushing back against the UK’s secret order to give the government access to encrypted iCloud files. The company has filed an appeal with the Investigatory Powers Tribunal, which deals with complaints about the “unlawful intrusion” of UK intelligence services and authorities, according to a report from the Financial Times.

Company wants to discourage other governments from using the same tactics; the appeal also likely objects to Apple being singled out for this requirement, analysts said.

Reason reported on the United Kingdom's demand for access to any Apple user's digital information stored in its cloud storage service, iCloud. Since those data are end-to-end encrypted by default, this would require the tech giant to create an intentional vulnerability in its security protocols—the likes of which could be exploited by sophisticated criminals or hostile governments.

Elon Musk has endorsed Apple's legal challenge against the UK government's demand for access to encrypted iCloud data. Apple has appealed the order, which they argue compromises user security, and has disabled its Advanced Data Protection feature for UK users in the meantime.

A first-of-its-kind legal challenge set to be heard this month, per reports Apple has reportedly filed a legal complaint with the UK's Investigatory Powers Tribunal (IPT) contesting the UK government's order that it must forcibly break the encryption of iCloud data.
