Investigatory Powers Bill — House of Lords, 2016-10-11
Topic: Law and Crime
Frederick Richard Penn Curzon (Conservative, Centre-right): My Lords, I am most grateful to the noble Baroness for speaking to her amendments so clearly, as she always does. Perhaps I may first address Amendments 40 and 41, which relate to Clause 34. I do not believe that these amendments are in fact necessary. I agree that in circumstances where an agency seeks to add something to a warrant, that should be possible only where it is both necessary and proportionate. That is what the Bill provides, and that necessity and proportionality test applies whether a name or description is being added, or where a factor is being added However, I do not agree that a necessity and proportionality test is relevant where a name, description or factor is simply being varied. In such a case, the conduct authorised by the Secretary of State and approved by the judicial commissioner is not changing in substance. An example might be where an individual is identified initially by a nickname but their true identity subsequently becomes known. I will give another example, which I hope will reassure the noble Baroness. During Committee noble Lords expressed concern about warrants against premises. If an agency applies for a warrant against a premises at, let us imagine, 25 Acacia Avenue and it turns out that it actually intended to target 125 Acacia Avenue, in that sort of case the original warrant should be cancelled and the error reported to the Investigatory Powers Commissioner —and an entirely new warrant should be sought. So there are two types of variation, if I may put it that way. One, I suggest, should not require the process that the noble Baroness has suggested; the other also should not require the process because it should be subject to an entirely fresh warrant. I hope that that provides her with the necessary reassurance Turning now to Amendment 66, as the noble Baroness explained, the amendment seeks to limit the number of persons that a targeted examination warrant issued under Part 5 may relate to. The amendment would clearly mean that any individual targeted examination warrant that relates to multiple persons for the purposes of a single investigation or operation under Clause 96(2)(c) could not relate to more than 50 persons. I believe that inserting such an arbitrary limit would be a mistake—I know the noble Baroness realises that it is an arbitrary figure—and that it would not add to the strong safeguards already provided for in the Bill The decision on whether a warrant is necessary and proportionate is rightly one for the issuing authority and the judicial commissioner. There may be circumstances in which the case for examining the material of more than 50 persons is entirely proportionate to what is sought to be gained from that task. For example, if the security and intelligence agencies are investigating UK-based users of websites hosting illegal child pornography, it would be detrimental and dangerous to limit the number of people they could investigate to a particular figure. This could in some cases result in material relating to dangerous subjects of interest escaping entirely appropriate examination simply because they were past the relevant number that would be set out in statute if this amendment or something like it were accepted Mandating that a targeted examination warrant must not relate to more than 50 people would mean either that vital operations could not proceed or that the intelligence agencies would on some occasions need to submit multiple applications for warrants relating to a single investigation or operation. That would needlessly increase the bureaucratic burden placed upon the agencies and the issuing authority while also hampering the ability of the issuing authority and the judicial commissioner to consider the operation in full. Such a restriction would add no additional rigour to the already robust double-lock process Introducing an arbitrary restriction does nothing to ensure that the principles of necessity and proportionality are upheld, but the role of judicial commissioners, already provided for by the Bill, does. That is why the Bill requires both the issuing authority and the judicial commissioner to consider, on a case-by-case basis, whether the breadth of a warrant is appropriate without the imposition of indiscriminate limits. In summary, the amendment has the potential to be damaging, needlessly bureaucratic or both, and I invite the noble Baroness not to press it.
