Apple is appealing against a British government order to create a "back door" to its encrypted cloud storage systems, the Investigatory Powers Tribunal (IPT) confirmed on Monday.
The IPT said in a written judgment that it had refused an application by the British government that "the bare details of the case", including that it was brought by Apple, be kept private.
The ruling follows a hearing in London last month, which was held in secret with media not allowed to attend.
The Washington Post reported in February that Britain had issued a "technical capability notice" to Apple to enable access to encrypted messages and photos, even for users outside the country, Reuters reported.
The iPhone maker in response removed its most advanced security encryption for cloud data, called Advanced Data Protection, for new users in Britain.
Details of the case have been shrouded in
secrecy
and neither Apple nor the British government have publicly confirmed the technical capability notice.
