No enactment or rule of law prohibiting or restricting the disclosure of information precludes a person from providing the First-tier Tribunal or the Upper Tribunal with information necessary for the discharge of—
its functions under the data protection legislation, or
its other functions relating to the Commissioner's acts and omissions.
But this section does not authorise the making of a disclosure which is prohibited by any of Parts 1 to 7 or Chapter 1 of Part 9 of the Investigatory Powers Act 2016.
Until the repeal of Part 1 of the Regulation of Investigatory Powers Act 2000 by paragraphs 45 and 54 of Schedule 10 to the Investigatory Powers Act 2016 is fully in force, subsection (2) has effect as if it included a reference to that Part.
