My Lords, I hope to provide the clarity that the noble Lord, Lord Kennedy, seeks and persuade the noble Lord, Lord Paddick, that this is not necessary in the Bill. The current authorisation period of 12 months is consistent with the authorisation for the use and conduct of CHIS, which will need to be in place before criminal conduct can be authorised. Keeping the Bill consistent with the powers laid out in Section 29 will ensure that this power remains operationally workable for the public authorities listed in the Bill.
In the updated CHIS code of practice that accompanies the Bill, it is clear that a criminal conduct authorisation should be relied upon for as short a duration as possible. There is also a requirement on authorising officers to undertake regular reviews to assess whether the authorisation remains necessary and proportionate, and is justified. An authorisation must be cancelled when that is no longer the case.
Authorisations will be specifically and narrowly drafted and, in many cases, the specificity of the authorisation will mean that the criminal conduct authorised is in effect narrowly time-limited. However, there will be occasions when this conduct necessarily extends longer than a four-month period; CHIS who are members of proscribed organisations is a good example of this.
