AND OTHERS v. THE UNITED KINGDOM   (Application no. 3455/05)                     JUDGMENT     STRASBOURG   19 February 2009       In the case of A. and Others v. the United Kingdom, The European Court of Human Rights, sitting as a Grand Chamber composed of: Jean-Paul Costa, President , Christos Rozakis, Nicolas Bratza, Françoise Tulkens, Josep Casadevall, Giovanni Bonello, Ireneu Cabral Barreto, Elisabeth Steiner, Lech Garlicki, Khanlar Hajiyev, Ljiljana Mijović, Egbert Myjer, Davíd Thór Björgvinsson, George Nicolaou, Ledi Bianku, Nona Tsotsoria, Mihai Poalelungi, judges , and Michael O’Boyle, Deputy Registrar , Having deliberated in private on 21 May 2008 and on 4 February 2009, Delivers the following judgment, which was adopted on the last-mentioned date: PROCEDURE 1.     The case originated in an application (no. 3455/05) against the United Kingdom of Great Britain and Northern Ireland lodged with the Court under Article 34 of the Convention for the Protection of Human Rights and Fundamental Freedoms (“the Convention”) by eleven non-United Kingdom nationals (“the applicants”), on 21 January 2005. The President acceded to the applicants’ request not to have their names disclosed (Rule 47 § 3 of the Rules of Court). 2.     The applicants were represented by Birnberg Peirce and Partners, a firm of solicitors practising in London. The United Kingdom Government (“the Government”) were represented by their Agent, Mr D. Walton, Foreign and Commonwealth Office. 3.     The applicants alleged, in particular, that they had been unlawfully detained, in breach of Articles 3, 5 § 1 and 14 of the Convention and that they had not had adequate remedies at their disposal, in breach of Articles 5 §   4 and 13 of the Convention. 4.     The application was allocated to the Fourth Section of the Court (Rule   52 § 1). On 11 September 2007 a Chamber of that Section, composed of Josep Casadevall, Nicolas Bratza, Giovanni Bonello, Kristaq Traja, Stanislav Pavlovschi, Lech Garlicki, Ljiljana Mijović, judges, and Lawrence Early, Section Registrar, relinquished jurisdiction in favour of the Grand Chamber, neither of the parties having objected to relinquishment (Article   30 of the Convention and Rule 72). 5.     The composition of the Grand Chamber was determined according to the provisions of Article 27 §§ 2 and 3 of the Convention and Rule 24. 6.     The applicants and the Government each filed observations on the merits. In addition, third-party comments were received from two London-based non-governmental organisations, Liberty and Justice, which had been given leave by the President to intervene in the written procedure (Article   36 § 2 of the Convention and Rule 44 § 2). 7.     A hearing took place in public in the Human Rights Building, Strasbourg, on 21 May 2008 (Rule 59 § 3).   There appeared before the Court: (a)     for the Government M r   D. Walton ,   Agent , M r   P. Sales QC, M s   C. Ivimy,   Counsel , M r   S. Braviner-Roman, M s   K. Chalmers, M r   E. Adams, M r   J. Adutt,   M r   L. Smith,   Advisers ; (b)     for the applicants Ms G. Pierce, Ms M. Willis Stewart, Mr D. Guedalla,   Solicitors , Mr B. Emmerson QC, Mr R. Husain, Mr D. Friedman,   Counsel .   The Court heard addresses by Mr Emmerson and Mr Sales and their answers in reply to questions put by the Court. THE FACTS I.     THE CIRCUMSTANCES OF THE CASE 8.     The facts of the case, as submitted by the parties, may be summarised as follows. A.     The derogation 9.     On 11 September 2001 four commercial aeroplanes were hijacked over the United States of America. Two of them were flown directly at the Twin Towers of the World Trade Centre and a third at the Pentagon, causing great loss of life and destruction to property. The Islamist extremist terrorist organisation al-Qaeda, led by Osama Bin Laden, claimed responsibility. The United Kingdom joined with the United States of America in military action in Afghanistan, which had been used as a base for al-Qaeda training camps. 10.     The Government contended that the events of 11 September 2001 demonstrated that international terrorists, notably those associated with al-Qaeda, had the intention and capacity to mount attacks against civilian targets on an unprecedented scale. Further, given the loose-knit, global structure of al-Qaeda and its affiliates and their fanaticism, ruthlessness and determination, it would be difficult for the State to prevent future attacks. In the Government’s assessment, the United Kingdom, because of its close links with the United States of America, was a particular target. They considered that there was an emergency of a most serious kind threatening the life of the nation. Moreover, they considered that the threat came principally, but not exclusively, from a number of foreign nationals present in the United Kingdom, who were providing a support network for Islamist terrorist operations linked to al-Qaeda. A number of these foreign nationals could not be deported because of the risk that they would suffer treatment contrary to Article 3 of the Convention in their countries of origin. 11 .     On 11 November 2001 the Secretary of State made a derogation order under section 14 of the Human Rights Act 1998 (“the 1998 Act” – see paragraph 94 below) in which he set out the terms of a proposed notification to the Secretary General of the Council of Europe of a derogation pursuant to Article 15 of the Convention. On 18 December 2001 the Government lodged the derogation with the Secretary General of the Council of Europe. The derogation notice provided as follows: “ Public emergency in the United Kingdom The terrorist attacks in New York, Washington, D.C. and Pennsylvania on 11   September 2001 resulted in several thousand deaths, including many British victims and others from seventy different countries. In its Resolutions 1368 (2001) and 1373 (2001), the United Nations Security Council recognised the attacks as a threat to international peace and security. The threat from international terrorism is a continuing one. In its Resolution 1373 (2001), the Security Council, acting under Chapter VII of the United Nations Charter, required all States to take measures to prevent the commission of terrorist attacks, including by denying safe haven to those who finance, plan, support or commit terrorist attacks. There exists a terrorist threat to the United Kingdom from persons suspected of involvement in international terrorism. In particular, there are foreign nationals present in the United Kingdom who are suspected of being concerned in the commission, preparation or instigation of acts of international terrorism, of being members of organisations or groups which are so concerned or of having links with members of such organisations or groups, and who are a threat to the national security of the United Kingdom. As a result, a public emergency, within the meaning of Article 15 § 1 of the Convention, exists in the United Kingdom. The Anti-terrorism, Crime and Security Act 2001 As a result of the public emergency, provision is made in the Anti-terrorism, Crime and Security Act 2001, inter alia , for an extended power to arrest and detain a foreign national which will apply where it is intended to remove or deport the person from the United Kingdom but where removal or deportation is not for the time being possible, with the consequence that the detention would be unlawful under existing domestic ‑ law powers. The extended power to arrest and detain will apply where the Secretary of State issues a certificate indicating his belief that the person’s presence in the United Kingdom is a risk to national security and that he suspects the person of being an international terrorist. That certificate will be subject to an appeal to the Special Immigration Appeals Commission (‘SIAC’), established under the Special Immigration Appeals Commission Act 1997, which will have power to cancel it if it considers that the certificate should not have been issued. There will be an appeal on a point of law from a ruling by SIAC. In addition, the certificate will be reviewed by SIAC at regular intervals. SIAC will also be able to grant bail, where appropriate, subject to conditions. It will be open to a detainee to end his detention at any time by agreeing to leave the United Kingdom. The extended power of arrest and detention in the Anti-terrorism, Crime and Security Act 2001 is a measure which is strictly required by the exigencies of the situation. It is a temporary provision which comes into force for an initial period of fifteen months and then expires unless renewed by Parliament. Thereafter, it is subject to annual renewal by Parliament. If, at any time, in the Government’s assessment, the public emergency no longer exists or the extended power is no longer strictly required by the exigencies of the situation, then the Secretary of State will, by order, repeal the provision. Domestic-law powers of detention (other than under the Anti-terrorism, Crime and Security Act 2001) The Government has powers under the Immigration Act 1971 (‘the 1971 Act’) to remove or deport persons on the ground that their presence in the United Kingdom is not conducive to the public good on national security grounds. Persons can also be arrested and detained under Schedules 2 and 3 to the 1971 Act pending their removal or deportation. The courts in the United Kingdom have ruled that this power of detention can only be exercised during the period necessary, in all the circumstances of the particular case, to effect removal and that, if it becomes clear that removal is not going to be possible within a reasonable time, detention will be unlawful ( R. v. Governor of Durham Prison , ex parte Singh [1984] All ER 983). Article 5 § 1 (f) of the Convention It is well established that Article 5 § 1 (f) permits the detention of a person with a view to deportation only in circumstances where ‘action is being taken with a view to deportation’ ( Chahal v. the United Kingdom (1996) 23 EHRR 413 at paragraph 112). In that case the European Court of Human Rights indicated that detention will cease to be permissible under Article 5 § 1 (f) if deportation proceedings are not prosecuted with due diligence and that it was necessary in such cases to determine whether the duration of the deportation proceedings was excessive (paragraph 113). In some cases, where the intention remains to remove or deport a person on national security grounds, continued detention may not be consistent with Article 5 § 1 (f) as interpreted by the Court in the Chahal case. This may be the case, for example, if the person has established that removal to their own country might result in treatment contrary to Article 3 of the Convention. In such circumstances, irrespective of the gravity of the threat to national security posed by the person concerned, it is well established that Article 3 prevents removal or deportation to a place where there is a real risk that the person will suffer treatment contrary to that Article. If no alternative destination is immediately available then removal or deportation may not, for the time being, be possible even though the ultimate intention remains to remove or deport the person once satisfactory arrangements can be made. In addition, it may not be possible to prosecute the person for a criminal offence given the strict rules on the admissibility of evidence in the criminal justice system of the United Kingdom and the high standard of proof required. Derogation under Article 15 of the Convention The Government has considered whether the exercise of the extended power to detain contained in the Anti-terrorism, Crime and Security Act 2001 may be inconsistent with the obligations under Article 5 § 1 of the Convention. As indicated above, there may be cases where, notwithstanding a continuing intention to remove or deport a person who is being detained, it is not possible to say that ‘action is being taken with a view to deportation’ within the meaning of Article 5 § 1 (f) as interpreted by the Court in the Chahal case. To the extent, therefore, that the exercise of the extended power may be inconsistent with the United Kingdom’s obligations under Article 5 § 1, the Government has decided to avail itself of the right of derogation conferred by Article 15 § 1 of the Convention and will continue to do so until further notice.” The derogation notice then set out the provisions of Part 4 of the Anti-terrorism, Crime and Security Bill 2001. 12 .     On 12 November 2001 the Anti-terrorism, Crime and Security Bill, containing the clauses which were to eventually become Part 4 of the Anti-terrorism, Crime and Security Act 2001 (“the 2001 Act” – see paragraph 90 below), was introduced into the House of Commons. The Bill was passed by Parliament in two weeks, with three days of debate on the floor of the House of Commons set aside for its 125 clauses in a restrictive programming motion, prompting both the Joint Committee of Human Rights and the Home Affairs Select Committee to complain of the speed with which they were being asked to consider the matter. 13.     The 2001 Act came into force on 4 December 2001. During the lifetime of the legislation, sixteen individuals, including the present eleven applicants, were certified under section 21 and detained. The first six applicants were certified on 17 December 2001 and taken into detention shortly thereafter. The seventh applicant was certified and detained in early February 2002; the ninth applicant on 22 April 2002; the eighth applicant on 23 October 2002; the tenth applicant on 14 January 2003; and the eleventh applicant was certified on 2 October 2003 and kept in detention, having previously been held under other legislation. B.     The derogation proceedings 14.     In proceedings before the Special Immigration Appeals Commission (SIAC – see paragraphs 91-93 below), the first seven applicants challenged the legality of the derogation, claiming that their detention under the 2001 Act was in breach of their rights under Articles 3, 5, 6 and 14 of the Convention. Each, in addition, challenged the Secretary of State’s decision to certify him as an international terrorist. 15.     On 30 July 2002, having examined both open and closed material and heard submissions from special advocates in addition to counsel for the parties and for the third party, Liberty, SIAC delivered its ruling on the legality of the derogation. It held that, on the basis of the open material, it was satisfied that the threat from al-Qaeda had created a public emergency threatening the life of the nation, within the meaning of Article 15 of the Convention, and that the closed material confirmed this view. SIAC further held that the fact that the objective of protecting the public from international terrorists could possibly have been achieved by alternative methods did not demonstrate that the measures actually adopted were not strictly necessary. Moreover, since the purpose of the detention was the protection of the United Kingdom, the fact that the detainee was at liberty to leave demonstrated that the measures were properly tailored to the state of emergency. SIAC rejected the applicants’ complaints under Article 3 of the Convention. It held that, in so far as they related to conditions of detention, the applicants should bring proceedings in the ordinary civil courts, and that SIAC had no jurisdiction to determine such a complaint as it was not a “derogation issue”. It further saw no merit in the applicants’ argument that detention for an indefinite period was contrary to Article 3. On this point, SIAC held that the detention was not indefinite, since it was governed by the time-limits of the 2001 Act itself and since the 2001 Act provided that each applicant’s certification was subject to automatic review by SIAC every six months. In any event, the mere fact that no term had yet been fixed for preventive detention did not give rise to a breach of Article 3. SIAC did not accept that Article 6 of the Convention applied to the certification process. The certification of each applicant as a suspected international terrorist was not a “charge” but instead a statement of suspicion and the proceedings before SIAC were not for the determination of a criminal charge. Furthermore, there was no relevant civil right at issue and Article 6 did not apply in its civil limb either. SIAC did, however, rule that the derogation was unlawful because the relevant provisions of the 2001 Act unjustifiably discriminated against foreign nationals, in breach of Article 14 of the Convention. The powers of the 2001 Act could properly be confined to non-nationals only if the threat stemmed exclusively, or almost exclusively, from non-nationals and the evidence did not support that conclusion. In paragraphs 94-95 of its judgment, SIAC held: “94.     If there is to be an effective derogation from the right to liberty enshrined in Article 5 in respect of suspected international terrorists – and we can see powerful arguments in favour of such a derogation – the derogation ought rationally to extend to all irremovable suspected international terrorists. It would properly be confined to the alien section of the population only if, as [counsel for the appellants] contends, the threat stems exclusively or almost exclusively from that alien section. 95.     But the evidence before us demonstrates beyond argument that the threat is not so confined. There are many British nationals already identified – mostly in detention abroad – who fall within the definition of ‘suspected international terrorists’, and it was clear from the submissions made to us that in the opinion of the [Secretary of State] there are others at liberty in the United Kingdom who could be similarly defined. In those circumstances we fail to see how the derogation can be regarded as other than discriminatory on the grounds of national origin.” SIAC thus quashed the derogation order of 11 November 2001 and issued a declaration of incompatibility in respect of section 23 of the 2001 Act under section 4 of the 1998 Act (see paragraph 94 below). It adjourned the first seven applicants’ individual appeals against certification (see paragraphs 24 - 69 below) pending the outcome of the Secretary of State’s appeal and the applicants’ cross-appeal on points of law against the above ruling. 16.     On 25 October 2002 the Court of Appeal delivered its judgment ( A. and Others v. Secretary of State for the Home Department [2002] EWCA Civ 1502). It held that SIAC had been entitled to find that there was a public emergency threatening the life of the nation. However, contrary to the view of SIAC, it held that the approach adopted by the Secretary of State could be objectively justified. There was a rational connection between the detention of non-nationals who could not be deported because of fears for their safety, and the purpose which the Secretary of State wished to achieve, which was to remove non-nationals who posed a threat to national security. Moreover, the applicants would be detained for no longer than was necessary before they could be deported or until the emergency was resolved or they ceased to be a threat to the country’s safety. There was no discrimination contrary to Article 14 of the Convention, because British nationals suspected of being terrorists were not in an analogous situation to similarly suspected foreign nationals who could not be deported because of fears for their safety. Such foreign nationals did not have a right to remain in the country but only a right, for the time being, not to be removed for their own safety. The Court of Appeal added that it was well established in international law that, in some situations, States could distinguish between nationals and non-nationals, especially in times of emergency. It further concluded that Parliament had been entitled to limit the measures proposed so as to affect only foreign nationals suspected of terrorist links because it was entitled to reach the conclusion that detention of only the limited class of foreign nationals with which the measures were concerned was, in the circumstances, “strictly required” within the meaning of Article 15 of the Convention. The Court of Appeal agreed with SIAC that the proceedings to appeal against certification were not “criminal” within the meaning of Article 6 § 1 of the Convention. It found, however, that the civil limb of Article 6 applied but that the proceedings were as fair as could reasonably be achieved. It further held that the applicants had not demonstrated that their detention amounted to a breach of Article 3 of the Convention. 17 .     The applicants were granted leave to appeal to the House of Lords, which delivered its judgment on 16 December 2004 ([2004] UKHL 56). A majority of the Law Lords, expressly or impliedly, found that the applicants’ detention under Part 4 of the 2001 Act did not fall within the exception to the general right of liberty set out in Article 5 § 1 (f) of the Convention (see Lord Bingham, at paragraphs 8-9; Lord Hoffman, at paragraph 97; Lord Hope, at paragraphs 103-05; Lord Scott, at paragraph 155; Lord Rodger, at paragraph 163; Baroness Hale, at paragraph 222). Lord Bingham summarised the position in this way: “9.     ... A person who commits a serious crime under the criminal law of this country may of course, whether a national or a non-national, be charged, tried and, if convicted, imprisoned. But a non-national who faces the prospect of torture or inhuman treatment if returned to his own country, and who cannot be deported to any third country, and is not charged with any crime, may not under Article 5 § 1 (f) of the Convention and Schedule 3 to the Immigration Act 1971 be detained here even if judged to be a threat to national security.” 18 .     The House of Lords further held, by eight to one (Lords Bingham and Scott with considerable hesitation), that SIAC’s conclusion that there was a public emergency threatening the life of the nation should not be displaced. Lord Hope assessed the evidence as follows: “118.     There is ample evidence within [the open] material to show that the government were fully justified in taking the view in November 2001 that there was an emergency threatening the life of the nation. ... [The] United Kingdom was at danger of attacks from the al-Qaeda network which had the capacity through its associates to inflict massive casualties and have a devastating effect on the functioning of the nation. This had been demonstrated by the events of 11 September 2001 in New York, Pennsylvania and Washington. There was a significant body of foreign nationals in the United Kingdom who had the will and the capability of mounting coordinated attacks here which would be just as destructive to human life and to property. There was ample intelligence to show that international terrorist organisations involved in recent attacks and in preparation for other attacks of terrorism had links with the United Kingdom, and that they and others posed a continuing threat to this country. There was a growing body of evidence showing preparations made for the use of weapons of mass destruction in this campaign. ... [It] was considered [by the Home Office] that the serious threats to the nation emanated predominantly, albeit not exclusively, and more immediately from the category of foreign nationals. 119.     The picture which emerges clearly from these statements is of a current state of emergency. It is an emergency which is constituted by the threat that these attacks will be carried out. It threatens the life of the nation because of the appalling consequences that would affect us all if they were to occur here. But it cannot yet be said that these attacks are imminent. On 15 October 2001 the Secretary of State said in the House of Commons that there was no immediate intelligence pointing to a specific threat to the United Kingdom: see Hansard (HC Debates, col 925). On 5 March 2002 this assessment of the position was repeated in the government’s response to the Second Report of the House of Commons Select Committee on Defence on the Threat from Terrorism (HC 348, para 13) where it was stated that it would be wrong to say that there was evidence of a particular threat. I would not conclude from the material which we have seen that there was no current emergency. But I would conclude that the emergency which the threats constitute is of a different kind, or on a different level, from that which would undoubtedly ensue if the threats were ever to materialise. The evidence indicates that the latter emergency cannot yet be said to be imminent. It has to be recognised that, as the attacks are likely to come without warning, it may not be possible to identify a stage when they can be said to be imminent. This is an important factor, and I do not leave it out of account. But the fact is that the stage when the nation has to face that kind of emergency, the emergency of imminent attack, has not been reached.” Lord Hoffman, who dissented, accepted that there was credible evidence of a threat of serious terrorist attack within the United Kingdom, but considered that it would not destroy the life of the nation, since the threat was not so fundamental as to threaten “our institutions of government or our existence as a civil community”. He concluded that “the real threat to the life of the nation ... comes not from terrorism but from laws such as these”. 19 .     The other Law Lords (Lords Bingham, Nicholls, Hope, Scott, Rodger, Carswell and Baroness Hale, with Lord Walker dissenting) rejected the Government’s submission that it was for Parliament and the executive, rather than the courts, to judge the response necessary to protect the security of the public. Lord Bingham expressed his view as follows: “42.     It follows from this analysis that the appellants are in my opinion entitled to invite the courts to review, on proportionality grounds, the derogation order and the compatibility with the Convention of section 23 [of the 2001 Act] and the courts are not effectively precluded by any doctrine of deference from scrutinising the issues raised. It also follows that I do not accept the full breadth of the Attorney-General’s submissions. I do not in particular accept the distinction which he drew between democratic institutions and the courts. It is of course true that the judges in this country are not elected and are not answerable to Parliament. It is also of course true ... that Parliament, the executive and the courts have different functions. But the function of independent judges charged to interpret and apply the law is universally recognised as a cardinal feature of the modern democratic State, a cornerstone of the rule of law itself. The Attorney-General is fully entitled to insist on the proper limits of judicial authority, but he is wrong to stigmatise judicial decision-making as in some way undemocratic. It is particularly inappropriate in a case such as the present in which Parliament has expressly legislated in section 6 of the 1998 Act to render unlawful any act of a public authority, including a court, incompatible with a Convention right; has required courts (in section 2) to take account of relevant Strasbourg jurisprudence; has (in section 3) required courts, so far as possible, to give effect to Convention rights and has conferred a right of appeal on derogation issues. The effect is not, of course, to override the sovereign legislative authority of the Queen in Parliament, since if primary legislation is declared to be incompatible the validity of the legislation is unaffected (section 4(6)) and the remedy lies with the appropriate minister (section 10), who is answerable to Parliament. The 1998 Act gives the courts a very specific, wholly democratic, mandate.” 20.     The majority therefore examined whether the detention regime under Part 4 of the 2001 Act was a proportionate response to the emergency situation, and concluded that it did not rationally address the threat to security and was a disproportionate response to that threat. They relied on three principal grounds: firstly, that the detention scheme applied only to non-nationals suspected of international terrorism and did not address the threat which came from United Kingdom nationals who were also so suspected; secondly, that it left suspected international terrorists at liberty to leave the United Kingdom and continue their threatening activities abroad; thirdly, that the legislation was drafted too broadly, so that it could, in principle, apply to individuals suspected of involvement with international terrorist organisations which did not fall within the scope of the derogation. On the first point, Lord Bingham emphasised that SIAC’s finding that the terrorist threat was not confined to non-nationals had not been challenged. Since SIAC was the responsible fact-finding tribunal, it was unnecessary to examine the basis for its finding, but there was evidence that “upwards of a thousand individuals from the UK are estimated on the basis of intelligence to have attended training camps in Afghanistan in the last five years”; that some British citizens were said to have planned to return from Afghanistan to the United Kingdom; and that the background material relating to the applicants showed the high level of involvement of British citizens and those otherwise connected with the United Kingdom in the terrorist networks. Lord Bingham continued: “33.     ... It is plain that sections 21 and 23 of the 2001 Act do not address the threat presented by UK nationals since they do not provide for the certification and detention of UK nationals. It is beside the point that other sections of the 2001 Act and the 2000 Act do apply to UK nationals, since they are not the subject of derogation, are not the subject of complaint and apply equally to foreign nationals. Yet the threat from UK nationals, if quantitatively smaller, is not said to be qualitatively different from that from foreign nationals. It is also plain that sections 21 and 23 do permit a person certified and detained to leave the United Kingdom and go to any other country willing to receive him, as two of the appellants did when they left for Morocco and France respectively ... Such freedom to leave is wholly explicable in terms of immigration control: if the British authorities wish to deport a foreign national but cannot deport him to country ‘A’ because of Chahal their purpose is as well served by his voluntary departure for country ‘B’. But allowing a suspected international terrorist to leave our shores and depart to another country, perhaps a country as close as France, there to pursue his criminal designs, is hard to reconcile with a belief in his capacity to inflict serious injury to the people and interests of this country. ... ... 35.     The fifth step in the appellants’ argument permits of little elaboration. But it seems reasonable to assume that those suspected international terrorists who are UK nationals are not simply ignored by the authorities. When [the fifth applicant] was released from prison by SIAC on bail ... it was on condition (among other things) that he wear an electronic monitoring tag at all times; that he remain at his premises at all times; that he telephone a named security company five times each day at specified times; that he permit the company to install monitoring equipment at his premises; that he limit entry to his premises to his family, his solicitor, his medical attendants and other approved persons; that he make no contact with any other person; that he have on his premises no computer equipment, mobile telephone or other electronic communications device; that he cancel the existing telephone link to his premises; and that he install a dedicated telephone link permitting contact only with the security company. The appellants suggested that conditions of this kind, strictly enforced, would effectively inhibit terrorist activity. It is hard to see why this would not be so. 36.     In urging the fundamental importance of the right to personal freedom, as the sixth step in their proportionality argument, the appellants were able to draw on the long libertarian tradition of English law, dating back to Chapter 39 of Magna Carta   1215, given effect in the ancient remedy of habeas corpus, declared in the Petition of Right 1628, upheld in a series of landmark decisions down the centuries and embodied in the substance and procedure of the law to our own day. ... In its treatment of Article 5 of the European Convention, the European Court also has recognised the prime importance of personal freedom. ... ... 43.     The appellants’ proportionality challenge to the order and section 23 is, in my opinion, sound, for all the reasons they gave and also for those given by the European Commissioner for Human Rights and the Newton Committee. The Attorney-General could give no persuasive answer.” 21.     In addition, the majority held that the 2001 Act was discriminatory and inconsistent with Article 14 of the Convention, from which there had been no derogation. The applicants were in a comparable situation to United Kingdom nationals suspected of being international terrorists, with whom they shared the characteristics of being irremovable from the United Kingdom and being considered a threat to national security. Since the detention scheme was aimed primarily at the protection of the United Kingdom from terrorist attack, rather than immigration control, there was no objective reason to treat the applicants differently on grounds of their nationality or immigration status. 22.     Although the applicants’ appeal had included complaints under Articles 3 and 16 of the Convention, the House of Lords did not consider it necessary to determine these complaints since it had found the derogation to be unlawful on other grounds. 23.     It granted a quashing order in respect of the derogation order, and a declaration under section 4 of the 1998 Act (see paragraph 94 below) that section 23 of the 2001 Act was incompatible with Articles 5 § 1 and 14 of the Convention in so far as it was disproportionate and permitted discriminatory detention of suspected international terrorists. C.     The certification proceedings: the “generic” judgment and appeals 24 .     Meanwhile, SIAC’s hearing of the applicants’ individual appeals against certification commenced in May 2003, after the Court of Appeal had given judgment in the derogation proceedings but before the above judgment of the House of Lords. 25.     For the purposes of each appeal to SIAC, the Secretary of State filed an “open statement” summarising the facts connected to the decision to certify each applicant and as much of the supporting evidence which the Secretary of State considered could be disclosed without giving rise to any risk to national security. A further, “closed” statement of facts and evidence was also placed before SIAC in each case. 26 .     On 29 October 2003 SIAC issued a “generic” judgment in which it made a number of findings of general application to all the appeals against certification. As regards preliminary issues, it found, inter alia , that it had jurisdiction to hear an appeal against certification even where the person certified had left the United Kingdom and the certificate had been revoked. It held that the tests whether reasonable grounds existed for suspicion that a person was a “terrorist” and for belief that his presence in the United Kingdom was a risk to national security, within the meaning of section 21 of the 2001 Act, fell “some way short of proof even on the balance of probabilities”. It further held that “reasonable grounds could be based on material which would not be admissible in a normal trial in court, such as hearsay evidence of an unidentified informant”. The weight that was to be attached to any particular piece of evidence was a matter for consideration in the light of all the evidence viewed as a whole. Information which might have been obtained by torture should not automatically be excluded, but the court should have regard to any evidence about the manner in which it was obtained and judge its weight and reliability accordingly. SIAC held that the detention provisions in the 2001 Act should be interpreted in the light of the terms of the derogation. The threat to the life of the nation was not confined to activities within the United Kingdom, because the nation’s life included its diplomatic, cultural and tourism-related activities abroad. Moreover, attacks on the United Kingdom’s allies could also create a risk to the United Kingdom, given the interdependence of countries facing a global terrorist threat. The derogation identified the threat as emanating from al-Qaeda and its associates. It was therefore necessary, in respect of both the “national security” and the “international terrorist” limbs of section 21 of the 2001 Act, to show reasonable grounds for suspicion that the person certified was part of a group which was connected, directly or indirectly, to al-Qaeda. Even if the main focus of the group in question was a national struggle, if it backed al-Qaeda for a part of its agenda and the individual nonetheless supported the group, it was a legitimate inference that he was supporting and assisting al-Qaeda. SIAC also made a number of findings of fact of general application concerning organisations alleged by the Secretary of State to be linked to al ‑ Qaeda. These findings were based on both “open” and “closed” material. Thus, it held, for example, that the Salafist Group for Call and Combat (GSPC), which was formed in Algeria in 1998, was an international terrorist organisation linked to al-Qaeda through training and funding, but that the earlier Algerian organisation, Armed Islamic Group (GIA), was not. The Egyptian Islamic Jihad (EIJ) was either part of al-Qaeda or very closely linked to it. The Chechen Arab Mujahaddin was an international terrorist group, pursuing an anti-West agenda beyond the struggle for Chechen independence, with close links to al-Qaeda. SIAC also identified as falling within the terms of the derogation a group of primarily Algerian extremists centred around Abu Doha, an Algerian who had lived in the United Kingdom from about 1999. It was alleged that Abu Doha had held a senior role in training camps in Afghanistan and had many contacts in al-Qaeda, including a connection with the Frankfurt cell which had been accused of plotting to bomb the Strasbourg Christmas Market in December 2000. Abu Doha was arrested in February 2001, following an extradition request from the United States of America, but his group remained active. 27.     The applicants appealed against SIAC’s ruling that evidence which might have been obtained by torture was admissible. For the purposes of the appeal, the parties agreed that the proceedings before SIAC to challenge certification fell within Article 5 § 4 of the Convention and as such had to satisfy the basic requirements of a fair trial. It was not, therefore, necessary to decide whether Article 6 also applied and the issue was left open. On 11 August 2004 the Court of Appeal, by a majority, upheld SIAC’s decision ([2004] EWCA Civ 1123). On 8 December 2005 the House of Lords held unanimously that the evidence of a suspect or witness which had been obtained by torture had long been regarded as inherently unreliable, unfair, offensive to ordinary standards of humanity and decency and incompatible with the principles on which courts should administer justice. It followed that such evidence might not lawfully be admitted against a party to proceedings in a United Kingdom court, irrespective of where, by whom and on whose authority the torture had been inflicted. Since the person challenging certification had only limited access to the material advanced against him in the proceedings before SIAC, he could not be expected to do more than raise a plausible reason that material might have been so obtai
