Tasking
Tasking is the assignment given to the CHIS by the persons defined at sections 29(5)(a) and (b) of the 2000 Act, asking him to obtain, provide access to or disclose information. Authorisation for the use or conduct of a CHIS will be appropriate prior to any tasking where such tasking involves the CHIS establishing or maintaining a personal or other relationship for a covert purpose.
Authorisations should not be drawn so narrowly that a separate authorisation is required each time the CHIS is tasked. Rather, an authorisation might cover, in broad terms, the nature of the source’s task. If there is a step change in the nature of the task that significantly alters the deployment, then a new authorisation may need to be sought. If in doubt, advice should be sought from the Investigatory Powers Commissioner.
It is difficult to predict exactly what might occur each time a meeting with a CHIS takes place, or the CHIS meets the subject of an operation. There may be occasions when unforeseen action or undertakings occur. When this happens, the occurrence must be recorded as soon as practicable after the event, followed by an assessment as to whether the existing authorisation covers the unforeseen action or undertaking. Where initial assessment indicates the existing authorisation may be insufficient, a review should be submitted so that the Authorising Officer can decide whether the existing authorisation is sufficient or whether a new authorisation is required.
Similarly, where it is intended to task a CHIS in a significantly greater or different way than previously identified, the persons defined at section 29(5)(a) or (b) of the 2000 Act must refer the proposed tasking to the authorising officer, who should consider whether the existing authorisation is sufficient or needs to be replaced. This should be done in advance of any tasking and the details of such referrals must be recorded. Efforts should be made to keep the number of authorisations per CHIS to the minimum necessary in order to avoid generating excessive paperwork.
Security and welfare
Any public authority deploying a CHIS should take into account the safety and welfare of that CHIS when carrying out actions in relation to an authorisation or tasking, and the foreseeable consequences to others of that tasking.
Before authorising the use or conduct of a CHIS, the authorising officer should ensure that a risk assessment is carried out to determine the risk to the CHIS of any tasking and the likely consequences should the role of the CHIS become known. This should consider the risks relating to the specific tasking and circumstances of each authorisation separately, and should be updated to reflect developments during the course of the deployment, as well as after the deployment if contact is maintained.
The ongoing security and welfare of the CHIS, after the cancellation of the authorisation, should also be considered at the outset and reviewed throughout the period of authorised activity by that CHIS.
Consideration should also be given to the management of any requirement to disclose information which could risk revealing the existence or identity of a CHIS. For example this could be by means of disclosure to a court or tribunal, or any other circumstances where disclosure of information may be required, and strategies for minimising the risks to the CHIS or others should be put in place.
Additional guidance about protecting the identity of the CHIS is provided at paragraphs 9.26 to 9.29 of the Home Office CHIS guidance.
The CHIS handler is responsible for bringing to the attention of the CHIS controller any concerns about the personal circumstances of the CHIS, insofar as they might affect:
- the validity of the risk assessment
- the conduct of the CHIS
- the safety and welfare of the CHIS
Where appropriate, concerns about such matters must be considered by the authorising officer, and a decision taken on whether or not to allow the authorisation to continue.
