Part 7: Bulk personal dataset warrants Section 215: Modification of warrants
This section explains the process by which class or specific BPD warrants can be modified, what constitutes a major or minor modification to a warrant and who is authorised to make or approve those modifications. The only modification that can be made to any warrant is to add, vary or remove an operational purpose. A major modification adds or varies an operational purpose; a minor modification removes one. This section also provides for major modifications in urgent circumstances. These provisions are consistent with equivalent sections in Part 6 of the Act.
	Subsection (11) provides that where it is not reasonably practicable for an instrument making a major modification to be signed by the Secretary of State, the instrument making the modification can be signed by a senior official designated by the Secretary of State to do so. But subsection (12) requires in such a case that the modification must be personally authorised by the Secretary of State. Such a modification is not an urgent modification and must still be approved by a Judicial Commissioner before taking effect.
