Part 2: Lawful interception of communications Chapter 1: Interception and examination with a warrant Section 31: Requirements that must be met by warrants
This section deals with the information which needs to be contained in Part 2 warrants. Subsections (2) to (8) specify the information a warrant must contain. If a warrant relates to a single person, organisation or set of premises, the warrant must name that person or organisation or those premises.
	A warrant may relate to a group of persons linked by a common purpose or activity, or to more than one person, organisation or set of premises linked to a single operation or investigation. In such a case the link must be described and the warrant must name or describe as many of the persons, organisations or sets of premises as is reasonably practicable.
	The warrant must specify the factors that are to be used to identify the communications that are to be intercepted or selected for examination. This section does not include an exhaustive list of possible factors but a factor may be an address or a telephone number, for example.
	Subsection (10) makes clear that communications from or intended for a person or organisation includes communications from or intended for anything owned, controlled or operated by that person or organisation.
