My Lords, Amendments 201ZA, 210ZB, 217A and 231ZA seek to insert a provision into the clauses that enable the modification of bulk interception, acquisition, equipment interference or bulk personal dataset warrants. The amendments would require that persons who can make a minor modification to remove an operational purpose from a warrant must keep under review the operational purposes on each bulk warrant. The intended effect of these amendments, as I understand it, is that such persons will be aware when one of those purposes is no longer necessary and can remove it from the warrant.
These amendments are not necessary because the relevant draft codes of practice, which were published when the Bill was introduced to Parliament, already make clear that the security and intelligence agencies must keep bulk warrants under ongoing review. In addition, the draft codes set out specific requirements in relation to operational purposes. This includes a requirement that the security and intelligence agencies will need to ensure that bulk warrants are relevant to
the current threat picture and will therefore need to identify operational purposes that need to be added to or removed from bulk warrants.
Further to the requirements in the draft codes, the government amendments, as I explained earlier, would create a requirement in the Bill that the heads of the intelligence services must maintain a list of all operational purposes. I set out the rationale and utility of that list in the preceding group of amendments. The provisions in the Bill and the detailed requirements set out in the draft codes of practice already make clear that the operational purposes on any bulk warrant will be kept under review. This will ensure that where an operational purpose is no longer necessary on a particular warrant it can be identified and removed. I hope the noble Lord will feel able to withdraw these amendments.
Amendments 201ZB, 210ZC, 217B and 231ZB make a modification to remove an operational purpose from a bulk warrant a major modification. Currently, a modification removing an operational purpose is a minor modification, meaning that it may be made by a Secretary of State or a senior official acting on their behalf. This amendment intends that such a modification would instead be subject to the double lock and must therefore be made by a Secretary of State and approved by a judicial commissioner before taking effect. That would be entirely unnecessary. A modification removing an operational purpose from a bulk warrant reduces the scope of the conduct that the warrant authorises, conduct that will already have been approved by the Secretary of State and a judicial commissioner. Subjecting such a modification to the double lock is superfluous. Accordingly, I invite the noble Lord to withdraw these amendments.
Amendments 201ZC and 217C relate to the modification of bulk warrants for the purpose of allowing examination of material after acquisition has ceased. These amendments would remove important technical provisions from the Bill. The Bill enables a bulk interception or bulk equipment interference warrant to be modified such that it no longer authorises the acquisition of any material but continues to authorise the selection of material for examination. This provision caters for limited circumstances where it may no longer be necessary or possible to continue the collection of data, such as where a communications service provider who is providing assistance in giving effect to the warrant goes out of business but where the data collected up to that point remain pertinent. In such circumstances, it may continue to be necessary and proportionate to examine data that have already been collected under the warrant.
The subsections that these amendments would remove simply clarify that a warrant that has been modified in this way remains a valid bulk warrant in spite of the provisions in Clauses 127(2) and 162(1). This is necessary because these clauses state that one of the conditions of the warrant is that its main purpose is to acquire data, but, of course, a warrant that has been modified in the manner I have described will no longer meet this condition, given that it will no longer authorise the collection of data. I hope the noble Lord will agree that these provisions are necessary and recognise that they serve only to reduce the activity that would have been authorised by the original unmodified warrant.
On Amendment 201ZJ, Clause 142 prohibits the selection for examination of intercepted content using criteria referable to an individual known to be in the British Islands, except where a targeted examination warrant—subject to the double lock—has been issued. I hope it is helpful if I draw the noble Lord’s attention to Clause 142(5), because there is one additional exception to this prohibition. That subsection addresses cases where there is a change of circumstances such that a person whose content is being selected for examination enters, or is discovered to be in, the British Islands. The subsection provides that selection for examination may continue in these circumstances for five working days with the approval of a senior official. This is vital to cater for circumstances such as where a member of an organised crime group travels into the British Islands. Any selection for examination after the five-day period will require the issuing of a targeted examination warrant.
I hope and believe that that explanation addresses the query the noble Lord, Lord Paddick, put to me. I understand his amendment as intended to capture the set of circumstances I just outlined, but it would also lead to a diminution in safeguards, given that it would enable selection for examination to continue for what I would judge to be an unnecessarily long period—in the absence of a targeted examination warrant—where there is a change of circumstances and someone has entered or is discovered to be in the UK. I hope that explanation will allow the noble Lord to feel comfortable in not pressing this amendment.
