Part 3: Authorisations for obtaining communications data Section 68: Use of filtering arrangements in pursuance of an authorisation
This section will apply in relation to the use of any request filter established under the power in section 67. The effect of subsection (2) is that the request filter may be used to obtain, process and disclose Part 3 data if, but only if, these uses have been specifically authorised by the authorisation.
	Subsection (3) sets out the matters which the designated senior officer must record within the authorisation to obtain Part 3 data. These include:
whether the Part 3 data may be obtained and disclosed by use of the filter; and
whether the processing of data under the filter is allowed.
	If the processing of data is allowed, then a description of data that may be processed must also be included.
	Subsections (4) and (5) reinforce the conditions that must be met before a designated senior officer can authorise the use of a request filter. These conditions are: that it is necessary to obtain the data for a public protection purpose; that it is necessary to obtain the data for a specific investigation or a specific operation; and that the conduct authorised by the authorisation, including specifically the use of the request filter, is proportionate to what an investigator is seeking to achieve.
	Subsections (2) to (5) will accordingly ensure that the use of any request filter under Part 3 is specifically authorised by the authorisation, is proportionate and is recorded within the authorisation.
