Investigatory Powers Bill — House of Commons, 2016-06-06
Topic: Law and Crime
Joanna Catherine Cherry (Scottish National Party, Centre-left): The Scottish National party has tabled a significant number of amendments to parts 2 and 5, and chapter 1 of part 9, which are under discussion, but given the constraints of time I will focus my fire on only a few of them, and mainly on part 2 and the system of judicial warrantry The Government have put their new double-lock system of warrantry at the heart of their arguments that there are sufficient safeguards in the Bill. In the SNP, we believe that the system of warrantry is too limited in scope and seriously deficient. We have tabled extensive amendments to extend the system of judicial warrantry beyond part 2, so that it would cover warrants to obtain, retain and examine communications data and police hacking warrants. We think the nature and scope of those warrants, and the grounds on which they are granted, are very important Amendments 267, 268, 272 and 306 to clause 15 deal with the scope of warrants. The problem with clause 15 as currently drafted is that it permits warrants to be issued in respect of people whose names are not known or knowable when the warrant is sought. This is confirmed by clause 27, which provides that a thematic warrant must describe the relevant purpose or activity and that it must "name or describe as many of those persons as is reasonably practicable" Our amendments would retain the capacity of a single warrant to permit the interception of multiple individuals, but require an identifiable subject matter or premises to be provided. We have tabled associated amendments to clause 27. Taken together, they would narrow the current provisions, which effectively permit a limitless number of unidentified individuals to have their communications intercepted It is not just the SNP who are concerned about the scope of the thematic warrants. We heard evidence in Committee from Sir Stanley Burnton, the Interception of Communications Commissioner, and from Lord Judge, the chief surveillance commissioner. Both expressed detailed concerns about the breadth of clause 15 as currently drafted. They said it was too wide and needed to be more focused. David Anderson QC, although in favour of thematic warrants, said that clause 15 as currently drafted is "considerably more permissive" than he had envisaged. There we have three very distinguished experts working in this field underlining the necessity of the amendments That is a real concern, because it takes us back to our old friend, or in our case our old enemy, bulk powers. If we create thematic warrants, communications intercepted under bulk powers can be trawled through thematically to look for groups of people sharing a common purpose or carrying out a particular activity. One difficulty with that is that it provides for an open-ended warrant that could encompass many hundreds or thousands of people. That is just not right. It is suspicionless interference. It is not targeted and it is not focused. I urge hon. Members on both sides of the House, if they are concerned about supporting an SNP amendment, to comfort themselves with the fact that it is an amendment the necessity of which has been underlined by persons as distinguished as the Interception of Communications Commissioner, the Chief Surveillance Commissioner and the independent reviewer of terrorism I now turn to the grounds, set out in clause 18, on which warrants may be granted, and to SNP amendments 212 and 213. The purpose of the amendments is to remove the economic wellbeing of the UK as a separate purpose for granting a warrant and to require that grounds for interception are tied to a threshold of reasonable suspicion of criminal behaviour. We have tabled similar amendments to the grounds for seeking warrants in relation to communications data under parts 3 and 4, and hacking under part 5. If these amendments are not allowed, people simply will not be able to predict when surveillance powers may be used against them, because the discretion granted to the Secretary of State is so broad as to be arbitrary The Joint Committee on the draft Bill recommended that the Bill include a definition of national security, which, of course, is the first ground. I call on the Government, not for the first time, to produce an amendment that defines national security. The Bill is sprinkled liberally with the phrase "national security". The Government need to tell us what they mean by that phrase, so I call on them to define it. This is not just theoretical or, as the hon. Member for North Dorset (Simon Hoare) called it, merely a law faculty debate; it is a serious issue about language being precise so that there can be some predictability. In the past, the courts have responded with considerable deference to Government claims of national security; they view them not so much as matters of law but as Executive-led policy judgments. As a legal test, therefore, "national security", on its own, is meaningless unless the Government attempt to tell us what they mean by it.
