Select Committee on Constitution Tenth Report


CHAPTER 2: Pre-charge detention and questioning

6.  Under Part 2 of the Bill, it is proposed to permit an extension of the time a terrorist suspect may be detained and questioned by police before a decision is made to charge or release him or her. The chain of decision-making envisaged by the Bill is set out in Appendix 2. In Appendix 3 we set out further information about how prosecutors determine when there is sufficient evidence to permit a charge to be brought.

7.  In the United Kingdom, the only lawful purpose of pre-charge detention and interrogation is investigatory—to build a case for particular charges. Detention before charge may not be used for general intelligence-gathering (for which the police and other agencies have a range of surveillance powers). Nor are pre-charge detention powers intended directly to protect the public from those under suspicion of involvement in terrorism (for which purpose there are other powers such as making control orders under the Prevention of Terrorism Act 2005 or, in relation to non-nationals, excluding a person from the United Kingdom).

8.  There are two basic constitutional questions that need to be addressed in designing a system for pre-charge detention. What should be the maximum permitted time of pre-charge detention? And who should be empowered to authorise such detention?

What should be the maximum period of detention?

9.  In the current debate there is no disagreement about the need to have in place a legal requirement for police and prosecutors to decide to charge or release a suspect within a specified time. The point in issue is what, in the circumstances of an investigation of serious terrorist offences, may properly be regarded as a necessary and proportionate time for police to gather sufficient evidence, given the fundamental requirement that suspects be charged and brought before a court promptly. In 2000, the Terrorism Act set that time at 7 days. It was increased to 14 days in 2003. In 2006 it was further extended to 28 days. The Bill seeks to create powers for the limit to be increased to 42 days on a temporary basis.

10.  In a free society, the purpose of placing time limits on the detention and questioning of suspects in an investigation is to guard against arbitrary detention. A requirement that the police and prosecutors must, within a defined period of time, either decide to charge a suspect and then bring him or her before an independent and impartial judge for the trial process to begin, or to release the person, ensures compliance with the rule of law by placing the accused under the control of a court. Time limits also serve to prevent prolonged interrogation that may in and of itself amount to coercion, with the attendant risk of false confessions.

11.  Although a time limit on police detention is widely accepted as a basic aspect of liberty of the person, international human rights instruments do not lay down any specific time limit. This is no doubt because, in the legal systems of the world, the respective roles of the police, prosecutors and the judiciary in the criminal justice process vary widely. The European Convention on Human Rights requires that those arrested shall be informed "promptly" of the reasons for their arrest and of any charge against them, and then be brought "promptly" before a judge (Article 5(2) and 5(3)).

12.  The Joint Committee on Human Rights argues that the Bill

"is incompatible on its face with the right of a terrorism suspect in Article 5(2) to be 'informed promptly' of any charge against him. For a suspect to be informed of the charge against him only after more than 28 days detention cannot be considered 'prompt'".[2]

13.  The Government take a different view, arguing that

"There is no specific [European Court of Human Rights] jurisprudence on the length of time that a person can be detained before he is charged but there is the overarching principle that detention under Article 5 must not be arbitrary. Extended pre-charge detention under these provisions [i.e. those in the Bill] is not arbitrary".[3]

14.  It falls outside our remit to examine the specific question of whether pre-charge detention of 42 days is or is not compatible with Article 5 of the ECHR; ultimately that is a question for the courts. As well as analysis of the case law of the European Court of Human Rights, assessment of the substance of the proposal to increase time limits of police detention requires analysis of the factual background, including the risk that the police may be unable to gather sufficient evidence to charge suspects within 28 days in complex cases and that an extension in pre-charge detention may lead to hostility to the police and a lack of confidence in the criminal justice system within some minority communities. Views on these matters have been gathered and analysed by the House of Commons Home Affairs Committee[4] and the Joint Committee on Human Rights.[5] We do not seek to duplicate the valuable work of those committees.

15.  It will be for the House as a whole to consider the rival legal analyses of the Joint Committee on Human Rights and the Government in deciding whether the Government have made a compelling case for the necessity of reserve powers to detain and question suspects for 42 days. If the House approves the time limit set out in the Bill, it will do so in the knowledge that the question of compliance with Convention rights is likely to be heard and ultimately determined by the courts.

Who authorises detention?

16.  A second basic constitutional question arising from the scheme of the Bill is "who should authorise pre-charge detention?" It is relatively uncontroversial that, in our system, the police should have initial decision-making power to determine that it is necessary to hold a suspect for a short length of time. In all cases, the general criminal law permits police officers—in the form of a custody officer unconnected with the investigation and later a more senior officer—to decide that it is necessary to hold a person for the purposes of gathering evidence for a short time. In the general law under the Police and Criminal Evidence Act 1984, that period is 36 hours. Application may then be made by police and prosecutors to a District Judge (Magistrates' Court) for a warrant authorising detention for up to a total of 96 hours (four days).

17.  Since the Terrorism Act 2000, a similar pattern of police then judicial authorisation has been followed in relation to terrorism investigations. The police have power to detain a suspect, subject to regular internal reviews by officers unconnected to the investigation, for an initial period of 48 hours. Thereafter, police and prosecutors may apply to a Magistrates' Court for warrants of further detention to detain a suspect for a maximum total period of (since amendments in 2006) 28 days.

18.  The Counter-Terrorism Bill proposes a triple layer of authorisations for extended detention: by the Home Secretary making a reserve power order; by Parliament approving an order; and finally by a senior judge hearing an application from the DPP under the terms of an order. At each stage, and almost certainly in rapid succession, broadly similar questions are decided: whether there is a need for extended detention and whether the police are conducting the investigation diligently and expeditiously.

19.  We now go on to consider whether the scheme of the Bill confuses the separate roles of the executive, Parliament and the judiciary.

The role of the executive in pre-charge detention

20.  Before the reforms introduced by the Terrorism Act 2000, when the main terrorism threats related to Northern Ireland, applications for detention beyond 48 hours (up to seven days in total) under the Prevention of Terrorism Acts were determined by the Secretary of State (i.e. a member of the executive). In 1988, the European Court of Human Rights held in Brogan and others v United Kingdom that detention authorised by the Secretary of State breached the requirement of Article 5(3) of the ECHR that a detained person "shall be brought promptly before a judge or other officer authorised by law to exercise judicial power" or released. In that case four suspects had been held for between 4 days and 6 hours and 6 days and 16 ½ hours. The Government of the day responded to this ruling by entering a derogation to permit the continuation of executive authorisation of detention for up to 7 days in relation to Northern Irish terrorism. The option of introducing judicial control of the authorisation process was rejected because the "Government concluded that no way could be found of doing so without undermining the independence of the judiciary particularly in Northern Ireland".[6]

21.  The Terrorism Act 2000 introduced judicial control in place of ministerial authorisation throughout the United Kingdom. The Government rejected calls for the retention of the Secretary of State's role in relation to Northern Ireland. For the Government, Lord Bassam of Brighton said that "I cannot accept that this matter is so inextricably linked to the executive that it cannot be transferred to the judiciary".[7] He added "Fundamentally, we believe that it is right in principle that matters relating to the liberty of the individual should be in the hands of the judiciary. Indeed, I should have thought that there would be general agreement on that point in this place".[8]

22.  We agree with the policy of the Terrorism Act 2000 that after an initial short period of detention authorised by police officers unconnected with the inquiry, any further authorisation should be a matter for the judiciary. That policy not only accords with the requirements of the ECHR but also reflects the basic constitutional principle that individual liberty is to be protected by the courts.

23.  We considered whether the proposals contained in the Bill undermined that principle. Lord West told us that they did not: "There is no change to the principle that the judiciary are responsible for authorising the continued detention of a suspect before charge" because "The Home Secretary's role is to decide if and when the 42 day higher limit should be made available as a matter of law" and "The Home Secretary will not be involved in the conduct of a particular investigation or the detention of individual suspects".

24.  Under the scheme of the Bill, there will be a connection between the decision of the Home Secretary to make a reserve power order and particular investigations which have led to the detention of one or more suspects. Indeed, the Home Secretary's decision to make an order will be prompted by a report from the DPP and a chief constable that there is an operational need to detain one or more suspects and that the particular police investigation is being conducted diligently and expeditiously (clause 24). Nonetheless, the Home Secretary's order will only provide the courts with the power to consider in individual cases whether detention up to 42 days is justified; the actual decision on whether to detain a particular suspect will continue to be taken by a judge.

25.  We are satisfied that the Bill preserves a constitutionally proper division of responsibilities between the Home Secretary and the judiciary. The Bill maintains the principle that in any given case it will be a judge, not a minister, who determines whether an individual suspect continues to be detained by the police. In this respect, the reserve power orders in this Bill are very different from the executive authorisation of detention included in earlier Terrorism Acts.

The role of Parliament in pre-charge detention

26.  Until now, Parliament has had two straightforward functions in relation to pre-charge detention. The first is to set the maximum permitted period of detention in primary legislation; we have noted above that in recent years Parliament has agreed to increase the time limit from 7 to 14 to 28 days. The second function is to have general oversight of the operation of counter-terrorism legislation, aided by the periodic reports of independent reviewers. Scrutiny of counter-terrorism policy falls particularly within the remit of the House of Commons Home Affairs Committee and the Joint Committee on Human Rights.

27.  Under the scheme proposed by the Bill, Parliament will be involved in several different ways:

(a)  The chairmen of three committees (the Home Affairs Committee, the Joint Committee on Human Rights and the Intelligence and Security Committee) will receive briefings on a Privy Counsellor basis about the Home Secretary's decision to make a reserve power order

(b)  Each House will debate and vote on a resolution approving a reserve power order, ahead of which the Home Secretary will lay a statement before Parliament and information about the independent legal advice she has received

(c)  If a reserve power order is approved by each House, Parliament will subsequently be informed by the Home Secretary on each occasion when a court grants an application by the DPP for a warrant authorising detention up to 42 days

(d)  Within six months of the reserve power order ceasing to be in force, Parliament will receive and scrutinise a report by the Independent Reviewer of Terrorism Legislation.

Tasks (a), (b) and (c) are new ones for Parliament.

Privy Counsellor briefings to three committee chairmen

28.  The Government will show the chairmen of the three committees mentioned above the police and DPP's report and the independent legal advice commissioned by the Home Secretary. In his letter, Lord West told us that "This will ensure that these key individuals are aware of the circumstances leading to the Home Secretary's decision and therefore able to participate fully in the subsequent debates on the issue" and that "Giving these documents to the chairs of these committees will therefore provide a level of reassurance to Parliamentarians and the public that the Home Secretary is acting properly and in accordance with the law".

29.  We are unconvinced that "Privy Counsellor briefings" to three committee chairmen will enhance the effectiveness of parliamentary scrutiny. The chairmen will be unable to share with their committees their assessment of the confidential information they have been shown—and may even refuse to view the information in the first place for this reason—or to consult their committees' legal and specialist advisers for guidance and analysis. It is also difficult to understand how having access to secret material will enable the chairmen to participate any more fully in parliamentary debates than other members. Moreover, we are concerned that there is a risk that the consensual ethos of select committees will be undermined if some members have privileged access to information not made available to others. In our view, this proposal is untenable and should be removed from the Bill.

Scrutiny and approval of the order declaring the reserve power exercisable

30.  Each House of Parliament will scrutinise, debate and within seven days decide whether or not to approve the reserve power order. Each House will have before it a statement by the Home Secretary that there is a "grave exceptional terrorist threat" (as defined by clause 22 of the Bill), that the reserve power is needed urgently and that the reserve power is compatible with Convention rights. The statement must not, however, include the name of the detained person or material that might prejudice the prosecution of that or any other person (clause 27(4)). Each House will also have a version of the independent legal opinion obtained by the Home Secretary, redacted to remove any sensitive or prejudicial material (clause 25(6)-(7)).

31.  Speaking at the Bill's Report Stage in the House of Commons, the Home Secretary explained that:

"Parliament's role in approving the order is not a negligible or an insignificant safeguard. I am constantly surprised at parliamentary colleagues who believe that their role is so insignificant in the thinking of a Home Secretary. Trust me—Home Secretaries think very carefully about what they have to explain to Parliament and what they need to have approved by Parliament … Parliament will be able to debate the general security threat; the progress of the investigation; the police numbers involved; the number of suspects detained; the outline of the plot; the what, why and when; the number of countries involved; whether the Home Secretary's decision was properly founded; and whether she had indeed received reports from the police and the DPP".[9]

32.  There are in our view significant difficulties with this stage of parliamentary scrutiny of the reserve power order. Although the order will, like normal legislation, be expressed in general terms—and will on the face of it merely permit the DPP to seek warrants for further detention from a court—the reality would be that the order would be made in relation to investigations into particular individuals. Indeed, as the Home Secretary acknowledged, the debate on the order is likely to include "the outline of the plot" and the "what, why and when". There are principled and practical objections to this arrangement.

33.  In the House of Commons the Speaker, and in the House of Lords the Leader, so far as normal practice provides, will advise on the parameters of permissible debate, but it is easy to foresee that members and select committees of both Houses will, in their questions, speeches and reports, have to tread a tightrope between on the one hand exercising parliamentary privilege of free speech to ensure that there is as full scrutiny as possible of the Home Secretary's course of action and on the other hand avoiding remarks—individual and collective—that may serve to prejudice fair trials and threaten the independence of the judiciary. Moreover, members of both Houses may be contacted by the families and legal representatives of the detained suspects—indeed, the proposed scheme might encourage such people to make representations to their MP and others.

34.  In their 1999 report, the Joint Committee on Parliamentary Privilege stated:

"The proper relationship between Parliament and the courts requires that the courts should be left to get on with their work. No matter how great the pressure at times from interest groups or constituents, Parliament should not permit itself to appear as an alternative forum for canvassing the rights and wrongs of issues being considered by the judicial arm of the state on evidence yet to be presented and tested. Although the risk of actual prejudice is greater in a jury trial, it would not be right to remove appeal cases or other cases tried without a jury from the operation of the rule. Restrictions on media comment are limited to not prejudicing the trial, but Parliament needs to be especially careful: it is important constitutionally, and essential for public confidence, that the judiciary should be seen to be independent of political pressures. Thus, restrictions on parliamentary debate should sometimes exceed those on media comment".[10]

35.  Even though reserve power orders do not engage the strict application of the sub judice rules, given that no charge will have been brought, the principle set out by the Joint Committee that Parliament should demonstrate respect for the role of the courts in debate should nonetheless apply in the context of these orders. Indeed, as the Joint Committee recognised, drawing the line in the application of the sub judice rules at the point of charge "does not remove the obligation on individual members and select committees to act responsibly and avoid actions which impede criminal investigations or abort trials".[11]

36.  In our letter, we asked Lord West to provide greater details—amplifying or adding to the matters referred to by the Home Secretary in the House of Commons on 11 June 2008—of what matters would in the Government's view be (a) appropriate and (b) inappropriate for debate in Parliament on a resolution to affirm a reserve power order. No such further details have been provided. We are unconvinced that the Government have properly thought through this aspect of their proposed scheme.

37.  Effective debates in Parliament would not only need to avoid touching on potentially prejudicial matters, they would also need to ensure that the order is subject to a degree of scrutiny commensurate with the fact that individual liberty would be at stake. Parliament will, however, almost certainly need to operate without fully knowing the factual background. The Home Secretary's legal advice is likely to be redacted to remove material the disclosure of which would be damaging to the public interest or might prejudice the prosecution of any person (clause 25(7)). We are concerned that Parliament would be asked, under the scheme of the bill, to make decisions that in the circumstances it is institutionally ill-equipped to determine.

38.  There has been little discussion as to whether the votes in each House to affirm a reserve power order will be subject to the guidance of party whips in the usual way or whether members will be permitted to have a free vote. If (as would seem likely) it is the former, we are concerned that a judge determining an application for extended detention will be called upon to exercise powers a matter of days or perhaps hours after a highly politically charged debate in Parliament in which there has been a clear division on party lines and over which there continues to be party political controversy. There is a risk that this will be perceived to undermine the independence of the judiciary.

39.  In developing this scheme, the Government have sought to devise ways in which Parliament may be involved in decision-taking about police detention of terrorist suspects. Insofar as the motivation is to ensure democratic accountability, this is understandable; in our view, however, it is muddled. The Bill risks conflating the roles of Parliament and the judiciary, which would be quite inappropriate. It is ill-advised to create a decision-making process that requires Parliament and the judiciary to ask and answer similar questions within a short space of time—or at all. Far from being a system of checks and balances, this is a recipe for confusion that places on Parliament tasks that it cannot effectively fulfil and arguably risks undermining the rights of fair trial for the individuals concerned.

The role of the judiciary in pre-charge detention

40.  In the scheme envisaged by the Bill, there may be judicial involvement in two main ways: in hearing applications by the DPP for warrants to detain suspects; and adjudicating on any judicial review challenge that might be brought against the reserve power order itself.

DPP's applications for a warrant to detain

41.  Under the scheme of the Bill, Schedule 8 to the Terrorism Act 2000 will be amended to set out amended procedures for seeking pre-charge detention warrants (Schedule 2 to the Bill). In England and Wales, the judge hearing the application by the DPP for detention beyond 28 days will be either a High Court judge or a designated circuit judge.

Judicial review of a reserve power order

42.  A second way in which the judiciary may be involved is if a judicial review challenge is made to the legality of the reserve power order on grounds that it is incompatible with Convention rights or is unlawful under domestic grounds of judicial review (illegality, irrationality and procedural impropriety).

43.  In relation to the Human Rights Act, the Joint Committee on Human Rights has considered whether a 42-day limit is compatible with Convention rights. They have concluded that "the legal framework which will be created by the Bill is both not compatible with the right to liberty in Article 5 of the ECHR and will inevitably lead to breaches of the rights in Article 5 in individual cases".[12]

44.  In relation to domestic grounds of review, the fact that an order has been passed by affirmative resolution in Parliament will not prevent the Administrative Court considering whether the order is ultra vires. In R (on the application of Javed) v Secretary of State for the Home Department [2001] EWCA Civ 789, the Court of Appeal quashed the Asylum (Designated Countries of Destination and Designated Safe Third Countries) Order 1996—which created a "white list" of countries to which failed asylum seekers could be returned without serious risk of persecution— on the ground that the Home Secretary had, in designating Pakistan, acted irrationally in his evaluation of the position of women and members of the Ahmadi community. Lord Phillips of Worth Matravers, for the court, said:

"The fact that, in the course of debate, the Secretary of State or others make statements of fact that support the legitimacy of the subordinate legislation, and that the House thereafter approves the subordinate legislation, cannot render it unconstitutional for the Court to review the material facts and form its own judgment, even if the result is discordant with statements made in parliamentary debate" (paragraph 37).

45.  The court held that Article 9 of the Bill of Rights 1689—"that the freedom of speech and debates or proceedings in Parlyament ought not to be impeached or questioned in any Court or place out of Parlyament"—did not prevent the court reviewing the delegated legislation. Lord Phillips stated:

"Subordinate legislation derives its legality from the primary legislation under which it is made. Primary legislation that requires subordinate legislation to be approved by each House of Parliament does not thereby transfer from the Courts to the two Houses of Parliament the role of determining the legality of the subordinate legislation" (paragraph 33).

46.  While there may be formidable practical difficulties in obtaining instructions from a detained suspect to question the legality of a reserve power order, there are a number of interest groups who would have standing to bring a public interest challenge. In determining whether the order is valid, the Administrative Court would make its own assessment as to whether there is "a grave exceptional terrorist threat" and whether the need for the reserve power is urgent. The court would not be precluded from reaching different views from that of the Home Secretary or Parliament. The elaborate decision-making scheme, involving delegated legislation, set out in the Bill provides far greater opportunities for legal challenge than would a straightforward statement in primary legislation of the maximum permitted detention period. It is a weakness of the Bill, not a strength, that it is likely to lead to high-profile litigation during a time when the response to terrorism will be a matter of high controversy.

Habeas corpus

47.  At the Third Reading of the Bill in the House of Commons, the Home Secretary undertook to look carefully at a new clause proposed by William Cash MP who sought to ensure that habeas corpus would not be restricted.[13] Habeas corpus is an ancient writ available from the High Court where an applicant or his legal representatives allege that he has been unlawfully deprived of his personal liberty. It is, in other words, a type of judicial review. In recent years it has fallen out of favour with practitioners; the modern judicial review procedure under Part 54 of the Civil Procedure Rules is generally seen as a more effective means of challenging detention. Habeas corpus also provides much narrower grounds of review since the courts have held that it may only be used to challenge "jurisdictional error" a mistaken view of legal pre-conditions for the exercise of a power) by the minister or other public authority responsible for the detention. We do not regard habeas corpus as significant to the debate about judicial control over extensions of detention time. Modern judicial review provides an equally robust mechanism for dealing with legal challenge.
