Investigatory Powers Bill

Joanna Cherry Excerpts

Report: 1st sitting: House of Commons
Monday 6th June 2016 Commons Chamber

[Keir Starmer]

I am grateful to the Minister—that was what the Opposition pressed for.

There have been differences of approach to the test for judicial commissioners. On the one hand, colleagues on both sides of the House have made a powerful argument that the judicial commissioners should retake the decision. On the other hand, others have argued that the decision should be reviewed. The amendment strikes a third route, which is to apply a review test but to confine it to the stricter end of the judicial review principles.

As hon. Members know, I have been a lawyer for many years and have dealt with many public law cases, as other hon. Members have. The difference between strict scrutiny and long-arm judicial review is very real —it is a material difference. That is why the manuscript amendment is highly significant.

[Joanna Cherry (Edinburgh South West) (SNP)]

It has been a pleasure to work with the hon. and learned Gentleman on the Bill. Like me, as a lawyer, he will have advised clients frequently on judicial review. He will no doubt agree that judicial review looks to the reasons given for a decision. There is no duty on the Secretary of State to give reasons for her decision on whether or not to grant a warrant. How can there be judicial review when no reasons are given?

[Keir Starmer]

The hon. and learned Lady made that very important point in the Bill Committee. Normally when decisions are subject to judicial review, there are reasons for the decision. What is envisaged is that the decision itself, plus such material as has been looked at by the Secretary of State, will be put before the judicial commissioner. There will not be reasons, which makes the task more difficult, but what is important about the test set out in the manuscript amendment is that the judicial commissioner must ensure that the duties under the privacy clause are complied with, which means that he or she will have to look at that underlying material. It might well be a good point to say, “If there are reasons, it would be an easier task,” but I do not believe the task cannot be performed without reasons. In due course, the judicial commissioners may say, “We need further help on particular issues.”

[Mr Grieve]

I am grateful to the Minister. Clearly, the more targeted a power can be, the better. Indeed, that was one of the reasons that the Committee expressed concern about whether the bulk power was required in the case of equipment interference. However, in classified evidence to us, the Government made the compelling case that simply relying on thematic powers or targeted powers would be likely to be insufficient and unsatisfactory. In changing our position, we have acknowledged that. However, that makes it all the more important that the safeguards should be properly in place. Those are the key amendments in this group that I wanted to bring before the House. I simply reiterate my earlier comment that the Government have really co-operated and moved a great deal in relation to this legislation. They have responded positively, as I shall be able to illustrate as we come to the further amendments.

[Joanna Cherry]

I have unashamedly tabled a lot of amendments to the Bill, including to part 8, and the Scottish National party will also support amendments tabled by others.

I pay tribute to the hon. and learned Member for Holborn and St Pancras (Keir Starmer), with whom I worked closely in Committee. There are areas of divergence between the SNP and Labour on the Bill, but it was a pleasure to work with him and I hope that there will be other occasions on which Labour and the SNP can work together harmoniously.

I recognise that the Government have made significant concessions on part 1 of the Bill. I welcome their attempt in new clause 5 to introduce an overarching privacy requirement. Their belated conversion to the central recommendation of the Intelligence and Security Committee is a tribute to the arguments advanced by Opposition Members in Committee. I have to say, however, that I prefer new clause 21, tabled by the Labour party, which trenchantly states that regard must be given to the Human Rights Act 1998. For reasons that other hon. Members have already given, that is important. It is encouraging to see the Government making reference in their own amendments to the Human Rights Act. That gives me hope that they might have retreated from their plan to repeal the Act even further than we had hoped. That could be one of the little bits of good news to come out of this exercise.

I am also happy to welcome Government new clause 6, and I thank the Minister for Security for acknowledging that it reflects an amendment that was tabled by my hon. Friend the Member for Paisley and Renfrewshire North (Gavin Newlands) and me. It is quite an historic occasion when the Government accept an amendment tabled by the SNP, and I should like to mark it. I just wish that they would look at more of my amendments, but I fear that they will not do so. We are, however, pleased that the Government have seen fit to respond to a number of the concerns raised in Committee. That said, I want to be clear that they will have to go an awful lot further before the Scottish National Party can contemplate giving the Bill our support.

As I said on Second Reading, we would like to be able to support some aspects of the Bill, because they are necessary for law enforcement across these islands and reflect some powers that are already in force in Scotland. It is also a good idea to consolidate the powers and to have a modern, comprehensive law. However, we remain concerned about the legality of some of the powers that are still on the face of the Bill and the fact that they significantly exceed, such as with the retention of internet connection records, what is authorised in other western democracies. We continue to have severe concerns about the bulk powers enabled by parts 6 and 7 of the Bill. We are pleased that the Government have conceded that there should be a properly independent review of the bulk powers, which was argued for by both Labour and SNP Members in Committee, but we are yet to see confirmation of the review’s remit. I want to associate myself with what the hon. and learned Member for Holborn and St Pancras said about the review needing to look not at whether the bulk powers are useful, but at whether they are necessary. We look forward to the publication of the correspondence between the Government and the Labour party, so that we can see what is being proposed. My hon. Friends the Members for Paisley and Renfrewshire North and for Glasgow North East (Anne McLaughlin) will address bulk powers and internet connection records in more detail tomorrow.

I led for the SNP in Committee, where we tabled numerous amendments to try to get the principle of suspicion-based surveillance to run throughout the Bill. We support the idea that warrants should be focused and specific and that oversight should be robust and meaningful. Nearly all our amendments were opposed or ignored by the Government, which is why we cannot give the Bill our support at this stage.

On Second Reading, the right hon. and learned Member for Rushcliffe (Mr Clarke) sought to mock me for making what he described as

“combative and partisan speeches in support of an abstention”.—[Official Report, 15 March 2016; Vol. 607, c. 847.]

He expressed a degree of confidence in a shared consensus across this House about the principles that we should be adopting. I am afraid that my experience in Committee has shown his confidence to be misplaced. The amendments tabled by the Government for debate today are only a partial response to our legitimate concerns. The Government need to pay more than lip service to the importance of privacy and to the principles of necessity and proportionality.

[Mr Alistair Carmichael (Orkney and Shetland) (LD)]

I am grateful to the hon. and learned Lady for giving way, because I agree with what she is saying. May I suggest that there is one means by which the Government could demonstrate good faith? In order to get to a vote on new clause 21, we will first have to vote down new clause 5. If the Government are serious about listening to the House, could they not withdraw new clause 5 to allow us to have a vote on new clause 21?

[Joanna Cherry]

That is an excellent suggestion that the Government should consider carefully.

I also mentioned on Second Reading that the United Nations special rapporteur had expressed concern about the Bill’s provisions, especially the bulk powers. That is why it remains the SNP’s position that until such time as a case has been made for the necessity of bulk powers, they should be removed from the Bill.

I make no apology for tabling numerous amendments, because this is a constitutionally important Bill. Their purpose is to try to bring the Bill into line with international human rights norms and to make it properly lawful. If the Bill is passed in its current form, there is a real risk that it will be the subject of challenge. Many of the threads running through it, such as the retention of data and bulk powers, have already been the subject of successful challenges or are awaiting the outcome of decisions. We need to be careful about passing powers into law when their legality has already been questioned by the European Court of Human Rights in Strasbourg, the European Court of Justice in Luxembourg, and a court in England.

In reality, I know that our amendments will not be accepted because we are already running out of time. We simply have not had enough time to consider the Bill. We have two days for Report, which I know is unusual, but we have short periods of time to speak about important parts of the Bill. I am only at the stage of making some introductory remarks and will have to curtail what I say about part 8 in the interest of other Members getting the right to speak. That will happen as we go through each part of programme motion.

[Mr George Howarth]

I share the hon. and learned Lady’s concern that maybe there is not enough time to consider the Bill as fully as she or I would like, but I am a bit confused. If that is the case, why did she not oppose the programme motion?

[Joanna Cherry]

I knew that that was a pointless exercise that would have eaten into the time that we have, so not opposing it was a practical decision.

[Mr John Hayes]

More pointedly, the Committee stage finished a day early, so why did she not debate the Bill for another day in Committee?

[Joanna Cherry]

If anyone reads the records of that Committee, they will see that I made more than my fair share of contributions. I do not have any problem with that. My issue is that other Members—the people sitting behind me, the Labour Members and Government Members—will not get a chance to speak and that we will not get a chance to vote on more than a handful of amendments. Given the degree of concern expressed about the Bill, it is frankly ridiculous that we will get to vote only on maybe eight or nine amendments over the next couple of days out of the hundreds of amendments that have been tabled. I am not ashamed to say that that is no way to legislate. We need to look at the way we go about things.

I am going to have to cut my cloth according to how much time is left, and I want to try to address some of the key SNP amendments to part 8 of the Bill, dealing first with amendment 465 and 466 to clause 194. Part 8 deals with oversight. At an earlier stage in the process, the Government said that they wanted to create a world-leading oversight body, but they have failed to do that. Our amendments seek to say that in addition to the investigatory powers and judicial commissioners there should be a separate body, known as the investigatory powers commission. It is not just some little notion of mine or of the SNP; it is what was recommended by the Royal United Services Institute’s independent surveillance review, the Joint Committee on the Draft investigatory powers bill, and by David Anderson QC’s investigatory powers review. David Anderson said that there should be a new independent surveillance and intelligence commission. It is a matter not only of what it is called; it is matter of what it actually does. Other hon. Members have tabled amendments relating to separating out the judicial and audit functions, and in the unlikely event that we get a chance to vote on them, the SNP will support them.

In written and oral evidence to the Bill Committee, we heard from Joanna Cavan, the head of the Interception of Communications Commissioner’s office. She reminded us that the judicial commissioners will deal only with some 2% of the applications falling within the remit of the oversight body. The remaining 98% will be subject to post-facto oversight only, so it is vital that that oversight is independent and robust. Creating a separate commission, as recommended by the three bodies I mentioned, would help to form a distinction between the approval and post-facto audit elements of the oversight body and would avoid the idea that judicial commissioners might be marking their own homework. That is what Labour’s amendment 146 seeks to address and the SNP will support it if we get a chance to do so. Joanna Cavan also told us that she had spoken to a number of the UK’s international oversight counterparts and that some had expressed surprised that the UK was going down the route of putting both the approval and the post-facto audit elements into the same body. Those amendments are crucial and I will be pressing them to a vote if I possibly can.

I turn now to the SNP’s amendments 467 and 469 and the question of the appointment of the judicial commissioners. I listened to what the hon. and learned Member for Holborn and St Pancras said in his speech, but the SNP does not think that Labour’s amendment goes far enough. The Government have made much of the main safeguard in the Bill being the role of judicial commissioners and the double lock, so it is vital that we get the judicial commissioner appointment process right. I suggest that, like the Justices of the United Kingdom Supreme Court, the commissioners should come from the jurisdictions and the judicial pool across the United Kingdom, not just the English Bench, and that the public must be confident that they are selected on merit, rather than because they can be trusted by government to be conservative or pro the state in their decision making. The SNP amendments therefore propose that, as well as having consultation with the Lord Chief Justice of England and Wales, the Lord Chief Justice of Northern Ireland and the Lord President in Scotland, these appointments should be subject to recommendations made by the independent Judicial Appointments Board of Scotland, the independent Judicial Appointments Commission in England and Wales, or the Northern Ireland Judicial Appointments Commission.

--- Later in debate ---

[Pete Wishart]

As usual, my hon. and learned Friend is making a powerful case. Does she agree that the judicial commissioners are the big flaw in the Government’s proposals today? This idea that somehow the Prime Minister could simply just agree with what has been suggested by judicial commissioners is concerning, because he could also disagree with what has been proposed and suggested. Does she have any concerns about that?

[Joanna Cherry]

I do, but let us suppose the judicial commissioners have been selected by an independent board. The Judicial Appointments Board of Scotland, the Judicial Appointments Commission—in England and Wales—and the Northern Ireland Judicial Appointments Commission are not made up just of lawyers; there are lay people and people from other walks of life on these bodies. That is to give the public confidence in the independent appointment process of the judiciary, and it is very important that the public—our constituents, who have concerns about how far the powers in this Bill are going—have confidence that the judicial commissioners who will be performing the oversight functions and enforcing the safeguards on this Bill are appointed independently, rather than being the right chap for the job being chosen. I choose my words advisedly there.

I am very conscious of not eating up too much time, Mr Deputy Speaker. I have discussed two crucial amendments that I would like to put to a vote on part 8. I have tabled other amendments that others will perhaps be able to speak about, such as the measures on post-notification following surveillance and the notification of errors. I briefly wish to turn to amendment 482, which is designed to put it beyond doubt that voluntary, unsolicited disclosures are protected and that a whistleblower is protected from criminal prosecution. The amendment reflects our concern that provisions in the Bill may inadvertently risk discouraging or preventing individuals within public authorities or agencies, or in communication services providers, from approaching the Investigatory Powers Commissioner with concerns or communicating with the commission frankly. Throughout the Committee process, we attempted to amend the Bill by inserting a public interest defence for whistleblowers. Regrettably, the Government were not prepared to accept it, but I was happy that when I proposed an amendment similar to this one to part 8, the Solicitor General said in Committee that he recognised the sentiment behind the amendment and was of a mind to give it further consideration. I urge the Government now to make a gesture by supporting this amendment, which I may push to a vote if I get the chance to do so.

[The Solicitor General]

The hon. and learned Lady is absolutely right in her recollection, and I am giving this matter anxious consideration. I would, however, point out that clause 203, dealing with the information gateway, underpins the important principles that she outlines about the rights of whistleblowers. I hope that is of some assistance.

[Joanna Cherry]

I hear what the Solicitor General says, but we took clause 203 into account when framing this amendment, and we remain of the view that it needs to be put beyond doubt in the Bill that whistleblowers will be protected from criminal prosecution and that there will be a public interest defence. I will mention that again when discussing other parts of the Bill.

Time prevents me from talking about the fact that the right of appeal in respect of the Investigatory Powers Tribunal is, regrettably, curtailed, but I do not think we are going to get to deal with that today. What I really want to say in conclusion is that this Bill seeks to put on a statutory footing very extensive powers, and it is vital that there is proper oversight of the way in which they are exercised. Part 8, as it stands, is pretty mealy-mouthed. It does not even implement the central recommendation of RUSI, the Joint Committee and David Anderson that there should be a separate investigatory powers commission. Without these amendments proposed by the SNP on key recommendations about oversight, we cannot support the Bill in its current form.

[Sir Simon Burns (Chelmsford) (Con)]

I am pleased to take part in this debate, although I shall only speak briefly because I know that many of my right hon. and hon. Friends, and Opposition Members, wish to participate. What we are debating in this group of amendments is crucial, because we are dealing with investigatory powers and, specifically, the role of technology in policing the modern age. Although I represent a constituency in Essex, which sometimes seems a world away from Westminster, I can tell hon. Members that my constituents and I worry about the same things: how we protect our country’s visible and invisible borders; how we keep our local community safe; and how we spot young people at risk of abuse or of going off the rails, so that we can do something about it before it is too late.

I certainly want to ensure that our liberties are fully understood and protected. That is why I welcomed the fact that during the Committee stage, which I took part in towards the end, the Government, my right hon. Friend the Home Secretary, the Solicitor General and the Minister for Security were prepared to listen to arguments—particularly those made by the hon. and learned Member for Holborn and St Pancras (Keir Starmer)—that sought to strengthen the protections without compromising the aims of the legislation. It was refreshing, in many ways, not to have the normal Punch and Judy politics, whereby everything the Opposition proposed must be wrong because the Government had not thought of it first. That give and take, which is shown in Government new clauses 5 and 6, and in some of the amendments, particularly amendments 33 to 38 and 45 to 48, is important in meeting concerns about protecting civil liberties without compromising the main aims of the Bill. Those amendments have been tabled to make it clear that warrants or other authorisations should not be granted where information could be reasonably obtained by less intrusive means.

More than anything, however, we have to ensure the liberty of my constituents to live quietly and peacefully, free from attack—that is, of course, the most fundamental liberty of all—and it must be protected from those who wish them harm. Today such people live everywhere, and they have the powers, through the internet and modern communication techniques, to be everywhere, plotting, planning and executing their evil deeds. That is why I was pleased to see the supporting provisions that this group of amendments address in ensuring that we have not only those protections for my constituents and others, but a sympathetic and reasonable approach to protecting people’s civil liberties.

This Bill goes further than ever before in terms of transparency, making clear the most sensitive powers available to the security and intelligence agencies and the strict safeguards that apply to them. The controls on bulk powers and the double lock protection, which requires a sign-off for action by not just the Home Secretary but independent commissioners, are extremely important in winning public confidence in the measures being proposed. That will be discussed in greater detail when those Committee provisions come before us later in our proceedings on this Report stage.

I ask those who worry about interception powers to remember the following simple facts relating to technical capability. Since 2010, the majority of MI5’s top priority British counter-terrorism investigations have used intercepted material in some form to identify, understand or disrupt plots to harm Britain and its citizens. In 2013, this material was estimated to form between 15% and 20% of the total intelligence picture in counter-terrorism investigations. Data obtained by the National Crime Agency suggested that in 2013-14, interception played a critical role in investigations that resulted in more than 2,200 arrests and the seizure of more than 750 kg of heroin and 2,000 kg of cocaine, more than 140 firearms, and more than £20 million.

I believe that the power to intercept communications from potentially very dangerous people has helped to keep my constituents and those of other right hon. and hon. Members much safer and much more secure in their homes, in their jobs and on the streets they walk every day; but I also recognise the calls from some that we must be careful not to risk the fundamental liberties of our democracy as we do battle with potential terrorists. The Government have clearly been mindful of the Wilson doctrine and have tabled amendments, which I welcome, to require that the Prime Minister approve, rather than just be consulted on, all equipment interference warrants relating to parliamentarians.

We must ensure that the powers that we give to our police and security agencies, while they are sufficiently transparent, are also fit for purpose. Terrorists and other threats to my constituents’ safety are constantly evolving and adapting their techniques to trump the safety system. They do not want to get caught; they want to catch us out, and that is why we must be prepared to adapt our rules to keep pace with technology. We cannot use an analogue approach to tackling criminals in a digital age. Such an attitude just is not safe, and I am not prepared to go back to Chelmsford and explain to my constituents there and in Great Baddow, Chelmer Village, Beaulieu Park and Old Moulsham that I was not prepared to support measures designed to make them all more secure.

I support the proposals that my right hon. Friend the Home Secretary has outlined to strengthen judicial commissioners’ oversight and give commissioners a role authorising national security notices and technical capability notices, but we must not lose sight of the essence of why we need these proposals: we need them to help our police and security agencies to better identify the internet activity of potential threats, and indeed victims of crime, so they can do their jobs more quickly and effectively.

The people outside Westminster who think this is about stopping people being rude on Twitter, or cleaning up the Facebook jungle, are wrong. The Bill is about protecting those rights—the right to be irreverent or to disagree; the right to surf the net without being at risk from those who would do us harm. The Government have acted properly by being prepared to listen and to think again to a degree that I have not often encountered in the past. They have considered carefully, and we should be careful not to assume that our police and security agencies do not need these powers as amended, with the new safeguards that have been promised today. For those reasons, I shall support my right hon. and hon. Friends in the Lobby tonight.

--- Later in debate ---

[Victoria Atkins (Louth and Horncastle) (Con)]

Will the right hon. and learned Lady give way?

[Joanna Cherry]

Will the right hon. and learned Lady give way?

[Ms Harman]

I will give way first to the hon. Member for Louth and Horncastle (Victoria Atkins) and then to the hon. and learned Member for Edinburgh South West (Joanna Cherry)

[Ms Harman]

It might well be useful for commissioners to have experience of both functions, but not at the same time and not using the same team of staff. I think ours is a relatively modest but important proposal. I am sure the hon. Lady can see that the arrangement could be clarified to create some sort of Chinese wall between the two functions. We are not suggesting that the functions be performed by separate organisations, but the hon. and learned Member for Edinburgh South West may be about to persuade us all that separate organisations are needed.

[Joanna Cherry]

I agree with the right hon. and learned Lady to an extent. Does her argument not boil down to the basic principle of Scots law and English law that no one should be a judge in their own cause? If one person grants a warrant then puts a different hat on and looks over whether that warrant was granted properly, they are being a judge in their own cause and there simply is not the proper transparency or oversight needed for public confidence.

[Ms Harman]

That is precisely my point. The Joint Committee on Human Rights and the independent reviewer have been helpful to the Government and bent over backwards in saying that separate organisations are not necessary—prima facie, one would say separate organisations are needed—but there should at the very least be Chinese walls. I therefore introduced the proposal in an amendment, and I hope to receive a response from the Government before the Bill goes to the Lords so that the matter can be looked at again, because we are a Joint Committee, and there are Members in the Lords who are eager to look at this. In the meantime, the Government’s responsibility, if they table amendments, is to submit a European convention on human rights memorandum with them. They have failed to do so. We regard those things as important. They are important for the House, so I urge them to do that. They should not table shedloads of amendments without producing an ECHR memorandum.

--- Later in debate ---

[Joanna Cherry]

Bearing in mind that the protection is for parliamentarians across these islands, does the right hon. Gentleman agree that the Presiding Officers in the Scottish Parliament, the Northern Ireland Assembly and the Welsh Assembly would have to be involved, not just the Speaker in this House?

[Andy Burnham]

That is a fair point, and the amendment tabled by my right hon. and learned Friend the Member for Camberwell and Peckham seeks to ensure that. Perhaps this is an issue that the Government need to think about. Of course the provisions should apply to Members of the Scottish Parliament, the Welsh Assembly and the Northern Ireland Assembly. The point made by the hon. and learned Member for Edinburgh South West (Joanna Cherry) should be accepted.

On journalists and journalistic sources, we welcome the fact that the Government have moved to put protections originally in the codes underpinning the Bill into the measure itself. We note, however, that the National Union of Journalists believes that wider protections are still needed, and the Government should continue to work with it to get that right.

Finally, on legal privilege there has been the least progress of all. Serious concerns have been expressed by the Bar Council and the Law Society about the fact that the provisions would weaken privacy protections currently enjoyed by lawyers, but those concerns are not adequately reflected in the Bill. It is disappointing that Ministers have yet to meet the legal bodies. [Interruption.] I did not quite hear what the Solicitor General said. I am happy to give way if he wants to clarify the position.

--- Later in debate ---

[Sir Edward Leigh]

I can see what the difference would be in a time of national crisis. The information will be clearly set out by the Home Secretary and the Prime Minister. I do not believe that it would be beyond the abilities of any Speaker now or in future to take an informed decision and to be convinced by the Prime Minister and the Home Secretary that the interception was not a political interference but a matter of national security.

All hon. Members agree on that—that the communications can be intercepted if it is a matter of national security—and we all agree that they should not be intercepted because it is politically expedient to do so. All I am asking is that the Speaker, who by the nature of his office does not consider political expediency, can say, “Yes. This is a matter of national security.” I do not believe that that is beyond his abilities. After all, he is ably assisted—is he not?—by the Clerk of the House and a band of parliamentary Clerks, most of whom have spent years accumulating knowledge, wisdom and experience of the ways of the House. They are not radicals or people who will take decisions lightly or wantonly. Together, they form a deposit of institutional memory, which the Prime Minister and No. 10, by the nature of their daily tasks of government and political management, can never be. They must always, necessarily, take a short-term view. That is not a criticism but the nature of the office.

Each of the privileges of this House, in addition to being daily fought for and won over the centuries, exists for a reason. Like many traditions and customs, we interfere with them at our peril. I appeal to the Minister of State, who is deeply aware of the importance of traditions and customs. We may wonder today why this or that one exists, but if we disregard them, we will soon find that the dangers they protect us from are very real.

We also may doubt the day will ever come when a Prime Minister would dare to authorise the monitoring of Members’ communications for politicised reasons, but it is therefore better to remove even the possibility of that temptation existing by simply requiring the Secretary of State to consult the Speaker. It has been said before but it is worth saying again. Nearly 375 years ago, William Lenthall reminded the sovereign that the Speaker had

“neither eyes to see nor tongue to speak in this place but as the House is pleased to direct me, whose servant I am here.”

All I am asking in amendment 1 is that that tradition be maintained. We would do well to continue to put our trust in that defender of our law and our liberties.

[Joanna Cherry]

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.

[Dr Murrison]

I am listening with great interest to the hon. and learned Lady. She will be aware that the Joint Committee on the National Security Strategy has long been trying to define “national security” but has failed to come up with an answer. Will she not accept that the term must necessarily remain loose?

[Joanna Cherry]

No, I do not accept that. As I say, the phrase is sprinkled throughout the Bill to justify very broad and intrusive powers, and it is incumbent on the Government to explain what they mean by it. We have heard powerful speeches and interventions from Labour Members about how these loose phrases can sometimes be misinterpreted to enable individuals who have done absolutely nothing wrong, such as trade unionists going about their lawful business, to have their livelihoods and communications interfered with. So if the Government want these powers, they have to define the grounds on which they can be exercised.

That takes me to economic wellbeing. The Joint Committee on the Bill said that economic wellbeing should be defined, but the Intelligence and Security Committee went further and said that it should be subsumed within the national security definition and that otherwise it was “unnecessarily confusing and complicated”. It was basically saying that if economic harm to the wellbeing of the UK was so serious that it amounted to a threat to national security, it would be covered by clause 18(2)(a). That was the point the ISC made. We do not need a separate category.

[Mr Grieve]

I intend to touch on this briefly when I speak. It is right to point out that, after making that recommendation, the Committee had the opportunity to hear considerable further evidence provided by the Government, and as a result we were unanimously persuaded that keeping “economic wellbeing” as a separate category was justified. I will amplify my remarks when I speak later, but that was the conclusion we reached.

[Joanna Cherry]

I do not wish to quibble with the right hon. and learned Gentleman’s conclusion, but unfortunately the rest of us have not been favoured with the basis on which he and his Committee reached it. I am yet to be convinced that the “economic wellbeing” ground is a stand-alone ground that cannot be subsumed within “national security”. If the Government can convince me otherwise, or want to try, I will listen, but I have yet to be convinced, despite having sat through many days of the Bill Committee.

Another problem with the grounds relates to the lack of any “reasonable suspicion” threshold. This recurs throughout the Bill. Our amendments would insert such a requirement. At present, intrusive powers can be authorised to prevent and detect serious crime and, in the case of communications data, even just to collect tax, prevent disorder or in the interests of public safety. These general purposes, however, are left wide open to broad interpretation and abuse if one does not also require a threshold of suspicion. A requirement of reasonable suspicion, when one invokes the purpose of preventing and detecting serous crime, would have the benefit of preventing the abusive surveillance of campaigners, unionists and victims by undercover police; police surveillance of journalists’ lawful activities; and surveillance by the agencies of law-abiding non-governmental organisations and MPs. This is not fanciful. We have seen law-abiding NGOs and MPs having their correspondence and activities interfered with in recent times, so these are not just theoretical examples.

The “reasonable suspicion” threshold was recently held to be necessary by the European Court of Human Rights in a case concerning the Russian interception regime, Zakharov v. Russia, with which many hon. Members will be familiar. The Solicitor General will try to make a distinction—if we had time, we could argue about that—but there is a widely held view that the standard set by the ECHR in that case is not met by the grounds in clause 18. I therefore urge fellow hon. Members to support our amendment to clause 18 to ensure that the United Kingdom’s investigatory powers regime meets international human rights standards.

It will be clear from what I have said already that the SNP very much shares Labour’s concerns about the monitoring of legitimate trade union activity. I understand that the Home Secretary has acknowledged those concerns and given some sort of assurance to the shadow Home Secretary. However, like Labour, the SNP will require an amendment to make that absolutely clear on the face of the Bill. If Labour Members want to push their amendment to a vote this evening, we will support it.
