Part 6: Bulk warrants Chapter 2: Bulk acquisition warrants Section 161: Requirements that must be met by warrants
This section sets out the information which must be specified on a bulk acquisition warrant.
	Subsection (3) requires that a warrant must set out the operational purposes for which any communications data obtained under the warrant may be selected for examination.
	Subsection (4) makes clear that any operational purpose specified on a bulk acquisition warrant must also be included on a separate, central list of all operational purposes to be maintained by the heads of the intelligence services. The maintenance of this list will assist the intelligence services in identifying new operational purposes that may need to be added to bulk warrants over time, such as where a new threat to national security has developed.
	Subsection (5) makes clear that a bulk acquisition warrant may specify however many operational purposes for which it is considered the examination of data obtained under the warrant will, or may, be necessary. This may include all of the operational purposes that are included on the central list maintained by the heads of the intelligence services. As a bulk acquisition warrant may lead to the collection of communications data that is relevant to a range of operational purposes, bulk acquisition warrants are likely to specify all operational purposes from the central list.
	Subsections (6) to (10) set out the processes by which the central list of operational purposes will be regulated and overseen. The addition of any operational purpose to the central list must be approved by the Secretary of State. These subsections also make clear that it is not sufficient for an operational purpose to use the wording of one of the statutory purposes: the Secretary of State must be satisfied that the purpose includes more detail before it may be added to the list. This ensures that intercepted content or secondary data may only be selected for examination for specific reasons.
	These subsections also specify that the central list of operational purposes must be shared with the Intelligence and Security Committee every three months and must also be reviewed at least annually by the Prime Minister.
