It is a pleasure to deal with the second group of amendments. It is a large group, which some hon. Members have described to me as “unprecedented”. I would not be so bold as to say that, having served a mere six years in this place. I concede, however, that the group is considerable. That perhaps reflects the huge and legitimate interest of Members of all parties in these particular parts of the Bill.
Parts 2 and 5 of the Bill were debated at length in Public Bill Committee. The Government have listened to what was said in those debates and we have brought back a number of amendments in response. These changes will strengthen protections for parliamentarians; enhance the safeguards for targeted thematic warrants; and provide greater assurances in respect of the obligations that might be placed on communications service providers.
Before I come on to the detail of the Government amendments, let me say a few words about one of the most important issues that we will discuss in this group: the authorisation of warrants.
When the Government published the draft Bill in November last year, my right hon. Friend the Home Secretary announced the intention that warrants for the most sensitive powers available to the security and intelligence agencies would be authorised by the Secretary of State and approved by a senior independent judge. This would maintain democratic accountability and introduce a new element of judicial independence into the warrant authorising process. This double lock represents the most significant change in our lifetimes to the way in which the security and intelligence agencies exercise their vital powers. This is ground-breaking, innovative and important in striking a balance between the public interest in protecting our citizens and the interests of privacy. There is a range of views in the House on the question of authorisations, and I am sure that we will have a productive and weighty debate on these matters this evening.
The amendments tabled by the hon. and learned Member for Holborn and St Pancras (Keir Starmer) seek to remove the reference to judicial review principles. The House will be aware that the Joint Committee that considered the draft Bill said that it was “satisfied” with the wording of the Bill and that judicial review principles would
“afford the Judicial Commissioner a degree of flexibility.”
That flexibility is important. It provides that judicial commissioners can undertake detailed scrutiny of decisions where appropriate, but it does not oblige judges to undertake forensic scrutiny of even the most straightforward warrants, because to do so would be unnecessary and would threaten the operational agility of the security and intelligence agencies.
In our debate on the first group of amendments, we had a mini-debate—we might have strayed slightly off piste—on the language that should be used in relation to the scrutiny that we want the judicial commissioners to deploy when considering their part in the double-lock mechanism. However, I believe that the manuscript amendment provides precisely the assurance that Opposition Members were seeking in Committee and in subsequent correspondence, and I am grateful to the hon. and learned Member for Holborn and St Pancras and other Opposition Members for agreeing to it. I am also grateful to the right hon. Member for Leigh (Andy Burnham)
for his involvement in these important matters. I believe that we now have an amendment that will satisfy the concerns of all hon. Members and provide the robust safeguard that we were all looking for. The wording that the parliamentary draftsmen have come up with ties in the privacy provision that we debated in the last group of amendments and puts this matter right at the heart of the Bill. We now have a robust double lock that will maintain the important distinction between the Executive and the judiciary. As I have said, this is truly ground-breaking.
I shall speak to the other Government amendments as quickly as I can, to ensure that other hon. Members can be accommodated in the debate. New clauses 9 and 13 will deliver on our commitment to strengthen the safeguards around so-called thematic warrants—that is, those targeted warrants that apply to a group of suspects rather than to an individual. They will introduce a new requirement that major modifications to warrants—adding the name of a gang member, for example—must be notified to a judicial commissioner as well as to the Secretary of State.
Amendments 97 and 54 will strictly limit the operation of modifications, making it clear that a warrant targeted at a single suspect cannot be modified to expand its scope to target several suspects. This builds on the assurances that I gave in Committee, and the provision will now be on the face of the Bill, should the amendments be accepted. New clauses 8 and 12 make it clear that modifications that engage the Wilson doctrine or legal professional privilege should be subject to the full double-lock authorisation.
