Investigatory Powers Bill — House of Lords, 2016-10-17
Topic: Law and Crime
Richard Keen (Conservative, Centre-right): Amendment 137A seeks to insert a provision into the Bill that would require the Investigatory Powers Commissioner to notify the subject of a targeted interception or equipment interference warrant in certain circumstances. The amendment tries to tightly draw those circumstances, and I am grateful to the noble Lord, Lord Paddick, for recognising in drafting it that a significant number of factors should rightly preclude such notification from taking place. Nevertheless, I still think the amendment could threaten to undermine the capabilities that law enforcement and the security and intelligence agencies rely on to pursue the most serious wrongdoers. The amendment recognises that notifying a person that they have been the subject of surveillance may have an immediate impact on an investigation—or it may have damaging effects on the public interest or national security more broadly That being the case, it is extremely difficult to envisage a scenario where notification could responsibly be allowed to occur. Notifying a person that their communications have been intercepted, irrespective of whether that notification included any further details about the methods used, would necessarily risk hindering a future investigation. For example, there will be circumstances where a terrorist or serious criminal who was previously the subject of a warrant will no longer be an active suspect in an investigation. Advising that individual that they have been the subject of interception may help them to evade detection if they were minded to return to or resume criminal activity On one reading, then, the amendment would not provide for disclosure other than where a person has been the subject of deliberate wrongdoing or a serious error. If that is the intention behind the amendment—and I fear it is not—it is redundant, because there is already provision in the Bill to notify people who have been the subject of serious errors The alternative, of course, is that the amendment should provide for individuals to be notified in a wider range of circumstances. I find that prospect troubling. As I say, it is never possible to know whether an individual will return to criminality in the future. Even if they do not, revealing the fact that they were the subject of a warrant may provide some small insight into the techniques and capabilities used by law enforcement and the security and intelligence agencies. That, in turn, would provide an avenue for the most determined and capable actors to piece together a picture of the agencies and how they work, handing an advantage to those we are working hard to pursue—let alone the prospect that they might seek disclosure by way of a review of the conduct of the authorities in order to determine exactly what methodology had been employed. For all these reasons, I hope the noble Lord will be prepared to withdraw this amendment I turn to Amendments 137B to 137F, which, as the noble Lord indicated, are in a sense consequential on his primary amendment, and which deal with error reporting as provided for in Clause 209. Clause 209 is of the utmost importance. It provides that if a person has been the subject of a serious error, and it would not be contrary to the public interest, the commissioner must inform that individual of the error and their right to apply to the Investigatory Powers Tribunal. The judicial commissioner must provide such details as considered necessary for the person to bring a claim Clause 209 seeks to maintain a very delicate balance between two important but competing interests. On one hand, there is the right of the individual who has suffered harm as a result of the error to seek some sort of redress. On the other, there is the long-standing security and intelligence agency principle of neither confirming nor denying that an individual has been the subject of investigatory powers. This principle is vital to the security and intelligence agencies, as it prevents those who would wish to do us harm launching spurious complaints and claims in order further to understand the agencies’ most sensitive capabilities. I hope the noble Lord will agree that, given the fine balance between these two principles, it is right that the decision be taken on a case-by-case basis by the commissioner, a senior member of the judiciary who will have full access to the facts on which to base their decision Amendments 137B and 137C would remove the commissioner’s discretion to make that judgment. He would no longer be able to consider how the wider public interest would be best served, and would instead be compelled to tell an individual if they had been the subject of a serious error, regardless of the consequences and the harm that might be caused. I do not think that is right. It is, for example, conceivable that an investigation into a dangerous criminal gang may result in action mistakenly being taken against an innocent associate of one of the gang members. That would be unfortunate, and the commissioner would undoubtedly want to ensure that remedial action was taken at an appropriate time. But before doing so, it is right that the commissioner should consider the public interest in informing the person, balanced against the risk of undermining an ongoing investigation, and that is what the clause as drafted provides for Amendment 137D seeks to require notification where the error has not caused serious harm or prejudice but may do so in the future. I do not think it necessary or appropriate, given the difficult balance that has to be struck here, for persons to be informed when there is such an error. This would put the commissioner in the difficult position of speculating on potential future consequences. Additionally, the commissioner does not get only one opportunity to assess the harm that has occurred. We would of course expect the commissioner to keep under review the consequences of an error and, if it resulted in harm at some point in the future, it would be open to the commissioner to inform the individual at that point. This seems a more sensible approach than putting the commissioner in the position of second-guessing what potential future consequences may one day occur or not occur.
