My Lords, I with begin with some of the observations made in your Lordships’ House regarding judicial oversight. On the observations of the noble Lord, Lord Strasburger, I have a double lock on my front door. The two locks work differently but they are equally effective. That really is the point of the double lock in the context of this legislation: the locks do indeed work differently but they are equally effective at the end of the day. I would adopt the observation of the noble and learned Lord, Lord Brown of Eaton-under-Heywood, that judicial oversight as it has developed provides us with a flexible standard of oversight, which in many senses is wide-ranging, as has been observed. But, of course, it is judicial oversight, and that is what we have to emphasise.
Turning to a point raised by the noble Baroness, Lady Hamwee, on working days a week, we consider that the present provision is appropriate. As to the calculation of the working day, the third working day will be calculated from the day after the warrant is issued. For example, if a warrant is issued on a Monday, it must be authorised by the commissioner by the close of Thursday. So it is the date of issue plus three working days.
Amendments 39 to 42, 165A, 167 and 168A would significantly change the so-called double-lock safeguard, such that the judicial commissioner would be taking their own decision rather than reviewing the Secretary of State’s conclusions as to whether the warrant is necessary and proportionate. The Committee will appreciate that the issue of authorisation has been a central feature in the debate on the Bill. Perhaps I might just give a brief potted history of its development.
The three reviews that shaped the draft Bill—by David Anderson QC, the Intelligence and Security Committee of Parliament and the Royal United Services Institute surveillance panel—made different recommendations in respect of authorisation. One called for full Secretary of State authorisation and the other two called for a hybrid judicial/executive model. It is noteworthy that none of them called for full judicial authorisation for all warrants. The Joint Committee that undertook pre-legislative scrutiny of the draft Bill supported the double-lock approach set out in the Bill, including the use of the well-established principles of judicial review. At Second Reading in the other place, there was very strong cross-party support for a government amendment that preserved the double
lock and the role of the judicial commissioner, while linking the judicial commissioner’s scrutiny to the new privacy clause, to put beyond doubt, if it needed to be, that the judicial commissioner would need to apply a sufficient degree of care to ensure that he or she had complied with duties imposed by the new protection of privacy clause in Part 1 of the Bill. So we are on well-trodden ground, and it is clear that there is strong support—including from senior members of the judiciary—for the approach set out in the Bill.
These amendments would confuse the distinct roles of the Executive and the judiciary and undermine democratic accountability—a point touched on by the noble Lord, Lord Rooker. It is surely right that a Secretary of State, who is accountable to Parliament and ultimately to the public, should be making the decision as to whether a warrant for the most intrusive powers is necessary and proportionate. Equally, it is entirely appropriate that a judicial commissioner should be carefully reviewing that decision. While the commissioner’s role is to review the original decision, your Lordships should be clear that this is a robust safeguard. Also, the judicial commissioners will have held or will be holding high judicial office and will be familiar with the principles of judicial review.
As amended in the other place, Clause 23 makes it clear that the commissioners’ review must involve careful consideration and ultimately if the Investigatory Powers Commissioner does not approve the decision to issue the warrant, it cannot come into force. The amendments I have referred to would also require the judicial commissioner to consider the reasons given for the decision to issue the warrant. The amendment is based on a misunderstanding of how warrants operate. The Secretary of State will receive a detailed application setting out the necessity and proportionality considerations. If they agree, they will issue the warrant. They do not have to give reasons for the decision beyond confirming that they personally consider that the warrant is necessary and proportionate. The judicial commissioner will review the decision of the Secretary of State based on the evidence provided to the Secretary of State in the application. If the commissioner thinks that the evidence in the application is not a sufficient basis for the decision that has been made, the commissioner will refuse to approve the decision. We would submit that it is in these circumstances that the double-lock mechanism is appropriate in this context, and accordingly I invite the noble Baroness to withdraw the amendment.
On Amendments 16 and 19, I have already touched on the reference to removing the term “working days”. Our position is that that is an appropriate way forward with these provisions, and I again invite the noble Baroness not to press these amendments.
Amendments 97 to 99 would significantly alter the double-lock safeguard for notices, such that the judicial commissioner would be taking their own decision rather than reviewing the conclusions of the Secretary of State as to whether the notice under Part 9 of the Bill is necessary and proportionate. The amendments would accordingly also remove the requirement for the judicial commissioner to apply the same principles as would be applied by a court in an application for
judicial review. As discussed during scrutiny by this House of similar clauses in Part 2 of the Bill, these amendments would confuse the distinct roles of the Executive and the judiciary, as I mentioned earlier. It is right that a Secretary of State, who is accountable to Parliament and ultimately the public, should make the decision whether it is necessary and proportionate to impose obligations on operators through the giving of a notice. Equally, it is entirely appropriate that a judicial commissioner should be carefully reviewing that decision. As I stated previously, the commissioner’s role is to review the original decision, and your Lordships should be clear that this is a robust safeguard.
One of the amendments would also require the judicial commissioner to consider the reasons given for the decision to give a notice, and again as I indicated before, this amendment appears to be based on a misunderstanding of the process of giving a notice because the reasons are not provided. In other words, under the Bill there is no need to give written reasons over and above those set out in the application itself. Again, in that context I would invite the noble Baroness not to press the amendments.
