8.  The facts of the case, as submitted by the parties, may be summarised as follows. 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. 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. 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 obtained and it was then for SIAC to initiate the relevant enquiries. The House of Lords therefore allowed the applicants’ appeals and remitted each case to SIAC for reconsideration ([2005] UKHL 71). 28.  SIAC’s conclusions as regards each applicant’s case are set out in paragraphs 29-69 below. Of the sixteen individuals, including the eleven applicants, detained under Part 4 of the 2001 Act, one had his certificate cancelled by SIAC. 29.  The first applicant was born in a Palestinian refugee camp in Jordan, is stateless, and was granted indefinite leave to remain in the United Kingdom in 1997. On 17 December 2001 the first applicant was certified by the Secretary of State as a suspected international terrorist under section 21 of the 2001 Act. On 18 December 2001 a deportation order was made on the same grounds. 30.  The first applicant was taken into detention on 19 December 2001. He subsequently appealed to SIAC against certification and the decision to make a deportation order. On 24 July 2002 he was transferred to Broadmoor Secure Mental Hospital. 31.  The first applicant and his representatives were served with the Secretary of State’s “open” material, including a police report which showed that large sums of money had moved through the four bank accounts in his name. SIAC and the special advocate instructed on behalf of the first applicant were in addition presented with “closed” evidence. Assisted by an interpreter, the first applicant gave oral evidence to SIAC and called one witness to testify to his good character. He also filed four medical reports concerning his mental health. SIAC observed in its judgment of 29 October 2003:
“We are acutely aware that the open material relied on against the Applicant is very general and that the case depends in the main upon assertions which are largely unsupported. The central allegation is that he has been involved in fund-raising and distribution of those funds for terrorist groups with links to al-Qaeda. It is also said that he has procured false documents and helped facilitate the movement of jihad volunteers to training camps in Afghanistan. He is said to be closely involved with senior extremists and associates of Osama Bin Laden both in the United Kingdom and overseas. His case is and always has been that he is concerned and concerned only with welfare projects, in particular a school in Afghanistan for the children of Arab speakers there and projects such as construction of wells and provision of food to communities in Afghanistan. He has also raised money for refugees from Chechnya. Any contact with so-called extremists has been in that context and he had no reason to believe they were terrorists or were interested in terrorism.
We recognise the real difficulties that the Appellant has in making this appeal. We have made appropriate allowance for those difficulties and his mental problems. We note [his counsel’s] concerns that there has been gross oversimplification by the Security Service of the situation which is, he submits, highly complex and a tendency to assume that any devout Muslim who believed that the way of life practised by the Taliban in Afghanistan was the true way to follow must be suspect. We note, too, that initially the Respondent asserted that all the Appellant’s fund-raising activities were for the purpose of assisting terrorism and that it was only when evidence was produced by the Appellant to show that there were legitimate charitable objectives that he accepted that at least some money was raised for those purposes. In so far as connections with named individuals are relied on, we bear in mind that some of them, who are alleged to be involved in terrorism, have appeals pending ... and that allegations against others have not been tested nor have alleged links been able to be explained.
...
[The first applicant’s counsel] accepted, as he had to, the unreliability of the Applicant’s evidence about his movements in the 1990s, but asked us not to hold it against him because of his mental state. We do not accept that we can do that. The lies were a deliberate attempt to rebut the allegation that he had been a mujahid in Afghanistan, saying that he spent three years in a Jordanian prison. There was an overstatement by the police of the amount involved through the bank account. This we accept, but there was still a substantial sum of money going through them. And [the applicant’s counsel] submitted that the allegation was that he had provided false documents for others not for himself. Thus his false Iraq passport was not material. It does however show an ability to obtain a false passport. [The applicant’s counsel] attacked the reliability of the intelligence relied on against the Appellant since it was only belatedly accepted that he had been involved in genuine charitable work and that some of the money going through his account and raised by him was for such a purpose. We recognise the danger that all activities by one who is under suspicion may be regarded as themselves suspicious and that there may not be a fair consideration of all material to see whether it truly does support the suspicion. We have considered all the material, in particular that which is closed, with that danger in mind.
As we have said, the open evidence taken in isolation cannot provide the reasons why we are dismissing this appeal and we sympathise with [the first applicant’s counsel’s] concerns that he had a most difficult task. We were not impressed with the Appellant as a witness, even making all allowances for his mental state and the difficulties under which he was labouring. He was often evasive and vague and has admittedly told lies in relation to his movements in the 1990s. His explanations about some of the transactions recorded in his bank accounts we have found difficult to follow or accept. We should say that we do not consider that the Respondent’s case is significantly advanced by what has been said about the Appellant’s involvement with Algeria or Chechnya; the case depends essentially on the evidence about the Appellant’s dealings with Afghanistan and with terrorists known to have links with al-Qaeda.
It is clear that the Appellant was a very successful fund-raiser and, more importantly, that he was able to get the money to Afghanistan. Whatever his problems, he was able to and was relied on to provide an efficient service. His explanations both of who were the well known terrorists whose children were at the school and of the various of the more substantial payments shown in the bank accounts are unsatisfactory. He was vague where, having regard to the allegations made against him, we would have expected some detail.
...
We have considered all the evidence critically. The closed material confirms our view that the certification in this case was correct. There is both a reasonable belief that the Appellant’s presence in the United Kingdom is a risk to national security and a reasonable suspicion that he is a terrorist within the meaning of section 21 of the 2001 Act. This appeal is accordingly dismissed.” 32.  In accordance with the terms of the 2001 Act, the first applicant’s case was reviewed by SIAC six months later. In its judgment of 2 July 2004, SIAC found that:
“The updated open generic material ... continues to show that there is a direct terrorist threat to the United Kingdom from a group or groups of largely North African Islamic extremists, linked in various ways to al-Qaeda.
Although some of his contacts have been detained, the range of extremists prominent in various groups was such that he would have no difficulty and retains the will and ability to add his considerable experience of logistic support to them in pursuit of the extremist Islamic agenda in the UK. The certificate is properly maintained.” 33.  SIAC reviewed the case again on 15 December 2004 and again found that the certificate should be maintained. 34.  The second applicant is a citizen of Morocco born on 28 February 1963. He entered the United Kingdom as a visitor in 1985 and was granted leave to remain as a student. On 21 June 1988 he was granted indefinite leave to remain on the basis of his marriage to a British citizen, which subsequently broke down. In 1990 and again in 1997 he applied for naturalisation, but no decision was made on those applications. In 2000 he remarried another British citizen, with whom he has a child. 35.  On 17 December 2001 the second applicant was certified by the Secretary of State as a suspected international terrorist under section 21 of the 2001 Act. A deportation order was made on the same date. The second applicant was taken into detention on 19 December 2001. He appealed against the certification and deportation order but, nonetheless, elected to leave the United Kingdom for Morocco on 22 December 2001. He pursued his appeals from Morocco. 36.  In its judgment of 29 October 2003, SIAC summarised the “open” case against the second applicant as follows:
“...
(1)  he has links with both the GIA and the GSPC [Algerian terrorist groups: see paragraph 26 above] and is a close associate of a number of Islamic extremists with links to al-Qaeda and/or Bin Laden.
(2)  he has been concerned in the preparation and/or instigation of acts of international terrorism by procuring high-tech equipment (including communications equipment) for the GSPC and/or Islamic extremists in Chechnya led by Ibn Khattab and has also procured clothing for the latter group.
(3)  he has supported one or more of the GIA, the GSPC and the Ibn Khattab faction in Chechnya by his involvement in fraud perpetrated to facilitate the funding of extremists and storing and handling of propaganda videos promoting the jihad. 9.  The Secretary of State’s open case expands on those allegations and further indicates the use of at least one alias and a pattern of association with individuals known or assessed to be involved in terrorism [five individuals were identified]. All these were described by [counsel for the Secretary of State] as ‘known Algerian Islamic extremists’. 10.  Witness B [for the Secretary of State] confirmed that the allegation against [the second applicant] is that he is a member of a network, rather than a member of any particular organisation such as the GSPC or the GIA.”
SIAC continued by explaining the findings it had made against the applicant:
“Like the other Appellants, [the second applicant] is not charged in these proceedings with a series of individual offences. The issue is whether, taking the evidence as a whole, it is reasonable to suspect him of being an international terrorist (as defined). When we look at the material before us, as we do, we treat it cumulatively. It might be that the material relating to fraud alone, or to clothing alone, or to videos alone, or to associations, would not by itself show that a person was in any way involved in terrorism or its support. But we need to assess the situation when various factors are found combined in the same person. Those factors are as follows. First is his involvement in acts of fraud, of which he must be aware but of which he seeks to provide no explanation, excusing himself apparently on the ground that he is not aware which particular act or acts the Secretary of State has in mind. Secondly, he has been involved in raising consciousness (and hence in raising money) about the struggle in Chechnya, and has been doing so in a specifically Islamic (rather than a merely humanitarian) context, using and distributing films which, according to the evidence before us, tend to be found in extremist communities. In the generic evidence, we have dealt with the Chechen Arab Mujahaddin and the significance of support for it which we accepted is given in full knowledge of its wider jihadist agenda. ... [He] has done so as a close associate of Abu Doha. Given the information we have about Abu Doha which, as we have said, we have no reason to doubt, we regard [the second applicant’s] claim that Abu Doha was doing nothing illegal (save that he was hiding his activities from the Russians) as entirely implausible. ... [He] has had associations with a number of other individuals involved in terrorism. They are for the most part specified by name in the open case but are not mentioned in his own statement. ...
These are the five features which meet in [the second applicant]. No doubt the Secretary of State could have made his case by demonstrating various combinations of them in a single person. With all five, we regard the case as compelling. We are entirely satisfied that the Secretary of State is reasonable in his suspicion that [the second applicant] supports or assists the GIA, the GSPC, and the looser group based around Abu Doha, and in his belief that at any time [the second applicant] is in the United Kingdom his presence here is a risk to national security.” 37.  The third applicant is of Tunisian nationality, born in 1963 and resident in the United Kingdom from about 1994. He was certified by the Secretary of State on 18 December 2001 and detained the following day. 38.  In its judgment of 29 October 2003, dismissing the third applicant’s appeal against certification, SIAC observed:
“The case against the Appellant, as framed in the open material, is that he is a key member of an extreme Islamist group known as the Tunisia Fighting Group (TFG). It is said that this group was formed during 2000 and had its origins in the Tunisian Islamic Front (known as the FIT since the name is in French). Its ultimate aim is said to be to establish an Islamic State in Tunisia. It is further asserted that the Appellant has been in regular contact with a number of known extremists including some who have been involved in terrorist activities or planning. Both the FIT and the TFG are said to have links with al-Qaeda.
The open material deployed against the Appellant is not at all substantial. The evidence which is relied on against him is largely to be found in the closed material. This has meant that he has been at a real disadvantage in dealing with the case because he is not aware of those with whom he is alleged to have been in contact.
...
In his statement the Appellant says that he has never heard of the TFG and is certainly not a member of it. ... We have no doubts that the TFG exists ... [and] also that it has links to al-Qaeda. Our reasons for so concluding must be given in the closed judgment.
In May 1998 the Appellant and some ten others were arrested in a joint Special Branch and Security Service operation pursuant to warrants under the Prevention of Terrorism Act. The Appellant was released without charge and in due course received £18,500 compensation for wrongful arrest. The arrests were in connection with allegations of involvement in a plot to target the World Cup in France. We of course give weight to the absence of any admissible evidence to support the Appellant’s involvement in the alleged conspiracy, but it is not and cannot be the answer to this appeal. We have to consider all the material to see whether there are reasonable grounds for a belief or suspicion of the kind referred to in section 21(a) or (b) of the 2001 Act.
...
We are satisfied that the Appellant is a member of the TFG, itself an international terrorist organisation within the scope of the 2001 Act, and that he has links with an international terrorist group. We appreciate that our open reasons for being so satisfied are sparse. That is because the material which drives us to that conclusion is mainly closed. We have considered it carefully and in the context of knowing the Appellant denies any involvement in terrorism or any knowing support for or assistance to terrorists. We have therefore been careful only to rely on material which cannot in our judgment have an innocent explanation.” 39.  SIAC reached similar conclusions in its periodic reviews of the case on 2 July and on 15 December 2004. 40.  The fourth applicant was born in Algeria in 1971 and first entered the United Kingdom in 1994. In May 1997 he was arrested and charged with a number of offences, including a conspiracy to export to Algeria material which it was alleged was to be used for the purposes of terrorism. It was alleged that he was a member of GIA. The case against the applicant was abandoned in March 2000 when a key witness, a Security Service agent, who was to give evidence concerning the need for civilians to defend themselves against atrocities allegedly committed by the Algerian government, decided that it was too dangerous for him to give evidence. 41.  In 1998 the fourth applicant married a French national. He became a French citizen in May 2001, although he did not inform the United Kingdom authorities of this. The Secretary of State certified him under section 21 of the 2001 Act on 17 December 2001 and he was detained on 19 December 2001. On 13 March 2002 he left for France, where he was interviewed on arrival by security officials and then set at liberty. Since he had left the United Kingdom, the certificate against him was revoked and the revocation was backdated to 22 March 2002. 42.  In its judgment of 29 October 2003, SIAC held that the backdating of the revocation meant that the fourth applicant could not be regarded as having been certified at the time he lodged his appeal and that, therefore, he had no right of appeal. It nonetheless decided to consider the appeal on the basis that this conclusion might be wrong. Since the Secretary of State could not reasonably have known at the time the certificate was issued that the applicant was a French citizen and could safely be removed to France, it could not be said on that ground that the certificate should not have been issued. SIAC therefore continued by assessing the evidence against him:
“In reaching our decision, we will have to consider not only the open but also the closed material. The Appellant appears to have suspected that he was the subject of surveillance over much of the relevant period.
We are conscious of the need to be very careful not to assume guilt from association. There must be more than friendship or consorting with those who are believed to be involved in international terrorism to justify a reasonable suspicion that the Appellant is himself involved in those activities or is at least knowingly supporting or assisting them. We bear in mind [his solicitor’s] concerns that what has happened here is an attempt to resurrect the prosecution with nothing to add from his activities since. Detention must be regarded as a last resort and so cannot be justified on the basis of association alone and in any event the guilt of the associates has never been established. ...
Nonetheless, continued association with those who are suspected of being involved in international terrorism with links to al-Qaeda in the light of the reasonable suspicion that the Appellant was himself actively involved in terrorist activities for the GIA is a matter which can properly be taken into account. The GSPC, which broke away from the GIA, has links to al-Qaeda and the Appellant has continued to associate with those who took to the GSPC rather than the GIA. We are in fact satisfied that not only was the Appellant actively involved initially with the GIA and then with the GSPC but also that he provided false documentation for their members and for the Mujahaddin in Chechnya as is alleged in the open statement. But we accept that his activities in 2000 and 2001 justify the use of the expression that he had been maintaining a low profile, and we make that observation having regard to both open and closed material. Nonetheless, a low profile does not mean that he is not properly to be regarded as an international terrorist within the meaning of section 21. An assessment has to be made of what he may do in the light of what he has done and the fact that he has shown willingness and the ability to give assistance and support in the past and continues the associations and to provide some help (e.g. the use of his van) is highly relevant.
We have not found this aspect of the Appellant’s case at all easy. We have given full weight to all [his solicitor’s] submissions which were so persuasively put before us but in the end have reached the view that, looking at the evidence as a whole, the decision to issue a certificate was not wrong. Accordingly, we would not have allowed the appeal on the facts.” 43.  The fifth applicant was born in Algeria in 1969. In his statement to SIAC he claimed to have developed polio as a child which left him with a permanently weak and paralysed right leg. He was arrested and tortured by the Algerian government in 1991, whereupon he left Algeria for Saudi Arabia. In 1992 he moved to Pakistan and travelled to Afghanistan on several occasions. In August 1995 he entered the United Kingdom and claimed asylum, alleging in the course of that claim that his leg had been injured by a shell in Afghanistan in 1994. His asylum claim was refused and his appeal against the refusal was dismissed in December 1999. The applicant married a French citizen and had a child with her. 44.  He was certified by the Secretary of State under section 21 of the 2001 Act on 17 December 2001 and detained on 19 December 2001. In its judgment of 29 October 2003, dismissing the fifth applicant’s appeal against certification, SIAC observed:
“The open statements provided to justify the certification do not refer to a great deal of source material and so consist mainly of assertions. As with most of these appeals, the main part of the evidence lies in closed material and so, as we are well aware, the Appellants have been at a disadvantage in that they have not been able to deal with what might be taken to be incriminating evidence. The Special Advocates have been able to challenge certain matters and sometimes to good effect. That indeed was the case in relation to a camp in Dorset attended by a number of those, including the Appellant, of interest to the Security Service. ...
The case against the Appellant is that he was a member of the GIA and, since its split from the GIA, of the GSPC. He is associated with a number of leading extremists, some of whom are also members of or associated with the GSPC, and has provided active support in the form of the supply of false documents and facilitating young Muslims from the United Kingdom to travel to Afghanistan to train for jihad. He is regarded as having undertaken an important role in the support activities undertaken on behalf of the GSPC and other Islamic extremists in the United Kingdom and outside it. All this the Appellant denies and in his statement he gives innocent explanations for the associations alleged against him. He was indeed friendly with in particular other Algerians in the United Kingdom and, so far as [the fourth applicant] was concerned, the families were close because, apart from anything else, their respective wives were French. He attended [the eighth applicant’s] mosque. He was an impressive preacher and the Appellant says he listened but was never involved. Indeed he did not know [the eighth applicant] except through Chechen relief, which the Appellant and many hundreds of other Muslims supported, and he had never spoken to him on the telephone. He had on occasions approached [the eighth applicant] at Friday prayers at the mosque if he wanted guidance on some social problem.”
SIAC referred to “open” surveillance reports which showed the applicant to have been in contact with other alleged members of GIA and GSPC, including at a camp in Dorset in July 1999. Further “open” evidence concerned his “unhelpful” and “not altogether truthful” responses to questioning by officers of the Security Service in July and September 2001. SIAC continued:
“Reliance is placed on various articles found in his house when he was arrested. These include a copy of the fatwa issued by Bin Laden. The Appellant says he had never seen it and could not explain its presence. A GSPC communiqué was, he says, probably one handed out at the mosque. Analysis of the hard drive of his computer showed it had visited an Internet site that specialised in United States military technology. This was not something which could be relevant to the Appellant’s studies. And a hand-drawn diagram of a missile rocket he has not seen before. It might, he thinks, have been in a book about Islam he had bought second hand from the mosque.
We note the denials, but we have to consider all the evidence. As will be clear from this judgment, we have reason to doubt some of the Appellant’s assertions. But the closed material confirms our view that there is indeed reasonable suspicion that the Appellant is an international terrorist within the meaning of section 21 and reasonable belief that his presence in the United Kingdom is a risk to national security. We have no doubt that he has been involved in the production of false documentation, has facilitated young Muslims to travel to Afghanistan to train for jihad and has actively assisted terrorists who have links with al-Qaeda. We are satisfied too that he has actively assisted the GSPC. We have no hesitation in dismissing his appeal.” 45.  On 22 April 2004, because of concerns about his health, the fifth applicant was released from prison on bail on strict conditions, which amounted to house arrest with further controls. In its review judgment of 2 July 2004, SIAC held:
“... in granting bail, [SIAC] did not revise its view as to the strength of the grounds for believing he was an international terrorist and a threat to national security. The threat could be managed proportionately in his case in view of his severe mental illness. That however is no reason to cancel the certificate. There might be circumstances in which he breaches the terms of his bail or for other reasons it was necessary to revoke it. The need for the certificate to continue must depend on whether the terms of the statute and of the derogation continue to be met.
A number of his contacts remain at large including some who are regarded as actively involved in terrorist planning. There is nothing to suggest that his mental illness has diminished his commitment to the extremist Islamic cause; he has the experience and capacity to involve himself once more in extremist activity. The bail restraints on him are essential; those are imposed pursuant to his certification and the SIAC dismissal of his appeal against it. The certificate is properly maintained.” 46.  On 15 December 2004, SIAC again reviewed the case and decided that the certificate should be maintained. 47.  The sixth applicant was born in Algeria in 1967 and was resident in the United Kingdom from 1989. The Secretary of State issued a certificate against him on 17 December 2001 and he was taken into detention on 19 December 2001. 48.  In its judgment of 29 October 2003, SIAC observed as follows:
“Although we have to make our decision on the basis both of the open and of the closed material, it is important to indicate the case against [the sixth applicant] as it has been set out by the Secretary of State in open material, because that is the case that [the sixth applicant] knows that he has to meet. In assessing his statement and the other evidence and arguments submitted on his behalf, we remind ourselves always that he is not aware of the Secretary of State’s closed material, but nevertheless that he is not operating entirely in a vacuum because of the open allegations; and we may test the Appellant’s own case by the way he deals with those allegations.
The Secretary of State’s case against [the sixth applicant] is summarised as follows:
(1)  he belongs to and/or is a member of the GSPC, and previously was involved with the GIA;
(2)  he has supported and assisted the GSPC (and previously the GIA) through his involvement in credit card fraud which is a main source of income in the United Kingdom for the GSPC;
(3)  from about August 2000, [the sixth applicant] took on an important role in procuring telecommunications equipment for the GSPC and the provision of logistical support for satellite phones by way of purchase and allocation of airtimes for those phones;
(4)  he has also played an important part in procuring telecommunications equipment and other equipment for the Mujahaddin fighting in Chechnya – that is to say the faction which until 2002 was under the command of Ibn Khattab.”
SIAC then reviewed the open evidence before it regarding the purchase by Abu Doha, assisted by the sixth and seventh applicants, of a number of satellite telephones and other telecommunications equipment to the value of 229,265 pounds sterling and the nature and extent of the connection between the sixth and seventh applicants. It concluded:
“In the circumstances we have set out, it appears to us that the Secretary of State has ample ground for suspicion that [the sixth applicant’s] procurement activities were directed to the support of the extremist Arab Islamist faction fighting in Chechnya. That support arises from [the sixth applicant’s] connections with and support of the GSPC. We emphasise, as is the case with other appeals as well, that it is the accumulation of factors, each lending support to the others rather than undermining other points, providing colour and context for the activities seen as a whole which is persuasive; it would be wrong to take a piece in isolation, thereby to diminish its significance and to miss the larger picture. The generic judgment supports these conclusions. These are activities falling centrally within the derogation. [The sixth applicant] has provided only implausible denials and has failed to offer credible alternative explanations. That is sufficient to determine his appeal, without making any further reference to the Secretary of State’s other allegations which, as was acknowledged in the open statement and in open evidence before [SIAC], can be properly sustained only by examination of the closed material.” 49.  SIAC reviewed the case on 2 July 2004 and on 28 February 2005 and, on each occasion, decided that there were still grounds for maintaining the certificate. 50.  The seventh applicant was born in Algeria in 1971 and apparently entered the United Kingdom using false French identity papers in or before 1994. On 7 December 2001 he was convicted of a number of driving offences and sentenced to four months’ imprisonment. He was certified by the Secretary of State on 5 February 2002 and taken into detention pursuant to the certificate as soon as his prison sentence ended on 9 February 2002. 51.  In its judgment of 29 October 2003, SIAC noted that the allegations against the seventh applicant were that he had been a member of GSPC since 1997 or 1998, and before that a member of GIA; that his contacts with leading GSPC members in the United Kingdom showed that he was a trusted member of the organisation; and that he had been involved with Abu Doha and the sixth applicant in purchasing telecommunications equipment for use by extremists in Chechnya and Algeria. It further noted that:
“[The seventh applicant] did not give evidence before [SIAC] and, indeed, chose not to attend the hearing of his appeal. His statement, which we have of course read, is in the most general terms, and, perhaps not surprisingly, [his counsel’s] submissions, both oral and written, were similarly general. [The seventh applicant’s] approach to the present proceedings of themselves and the fact that he did not give oral evidence or make any detailed written statement are not matters to be put in the scale against him. We well understand the difficulty that Appellants have in circumstances where the allegations against them are only summarised and where much of the evidence on which those allegations are based cannot, for reasons of national security, be communicated to the Appellants themselves. However, [the seventh applicant] is in the best position to know what his activities and motives have been in the relevant period. Nothing prevents him from giving a full description and account of those activities if he wishes to do so. The fact that he has chosen to provide no detailed account of his activities means that he has provided no material to counter the evidence and arguments of others.”
SIAC concluded that the open and closed material supported the allegations against the seventh applicant and it dismissed his appeal. 52.  In its review judgments of 2 July and 15 December 2004, SIAC decided that the certificate should be maintained. 53.  The eighth applicant is a Jordanian national, born in Bethlehem in 1960. He arrived in the United Kingdom on 16 September 1993 and claimed asylum. He was recognised as a refugee and granted leave to remain until 30 June 1998. On 8 May 1998 he applied for indefinite leave to remain but the application had not been determined at the time of the coming into force of the 2001 Act. 54.  The eighth applicant was convicted in absentia in Jordan for his involvement in terrorist attacks there and in relation to a plot to plant bombs to coincide with the millennium. He was investigated in February 2001 by anti-terrorism police officers in connection with a plot to cause explosions at the Strasbourg Christmas Market in December 2000, but no charges were brought against him. When the 2001 Act was passed he went into hiding. He was arrested on 23 October 2002 and was immediately made the subject of a section 21 certificate and taken into detention. On the same date, a deportation order was made against him. 55.  In its judgment of 8 March 2004, dismissing the eighth applicant’s appeal against certification, SIAC observed as follows:
“[The eighth applicant’s counsel], on instructions from the Appellant, informed us that his client had chosen not to attend the hearing or to participate in any way. He had read the decisions relating to the Appellants who had been certified when the 2001 Act came into force and the generic judgment and so felt certain that the result of his appeal was a foregone conclusion. There had been many references to his role in the other appeals and some had been certified and detained, at least in part, on the basis that they associated with him. Since that association was regarded as sufficient to justify their continued detention, he considered that the decision on his appeal had, in effect, already been taken. He had chosen not to play any part precisely because he has no faith in the ability of the system to get at the truth. He considered that the SIAC procedure had deliberately been established to avoid open and public scrutiny of the respondent’s case, which deprived individuals of a fair opportunity to challenge the case against them.
Having said that, [the eighth applicant’s counsel] made it clear that the appeal was not being withdrawn. It was accordingly necessary for us to consider it and to take into account the statement made by the Appellant. [His counsel] emphasised a number of matters which, he suggested, should be regarded as favourable to the Appellant’s contention that he was not and never had been involved in terrorism within the meaning of the 2001 Act. Furthermore, the allegations showed that a distorted and over-simplified view was being taken by the security services of the Appellant’s activities and his role as a respected teacher and believer in the rights of Islamic communication throughout the world.
We should make it clear that we have considered the case against the Appellant on its merits. We have not been influenced by any findings made in other appeals or the generic judgments. One of the reasons why this judgment has taken a long time to be prepared was the need for us to read through and consider the evidence, both open and closed, that has been put before us. There is much more of it than in most of the other appeals. That is a reflection of the fact that the Appellant has been associated with and had dealings with many of the others who have been certified and with individuals and groups themselves linked to al-Qaeda. We see no reason to dissent from the views expressed in the generic judgment of the significance of the various individuals and groups referred to in it. But that does not mean we have therefore automatically accepted its views. We draw attention to the fact that the panel which produced the generic judgment was not the same constitution as this panel and that such input as there was by the chairman of this panel to the generic judgment was limited to issues of law. We have considered the case against the Appellant on the material put before us in this appeal. ...
When it came to the closed session, the Special Advocates informed us that after careful consideration they had decided that it would not be in the Appellant’s interests for them to take any part in the proceedings. We were very concerned at this, taking the view that the decision was wrong. The appeal was still being pursued and the Appellant did not know what was relied on against him in the closed material. We were unable to understand how in the circumstances it could not be in his interests for the Special Advocates, at their discretion, to elicit or identify matters favourable to the Appellant and to make submissions to us to seek to persuade us that evidence was in fact unreliable or did not justify the assessment made. When we asked [one of the two Special Advocates appointed on behalf of the eighth applicant] to tell us why he had decided as he had he told us that he could not do so since to do so would not be in the Appellant’s interest. We adjourned to enable the Special Advocates to seek to discover from the Appellant through his representatives whether he did wish them to do what they could on his behalf and we also contacted the Solicitor-General who had appointed the Special Advocates to seek her help in trying to persuade them to assist us. The Appellant’s representatives indicated that they had nothing to say on the subject and the Solicitor-General took the view that it would be wrong for her to intervene in any way. Our further attempts to persuade the Special Advocates to change their minds were unsuccessful and since we could not compel them to act in any particular way we had to proceed without them. [Counsel for the Secretary of State], at our request, identified various matters which might be regarded as possibly exculpatory and we ourselves raised other matters in the course of the closed hearing.
We are conscious that the absence of a Special Advocate makes our task even more difficult than it normally is and that the potential unfairness to the Appellant is the more apparent. We do not doubt that the Special Advocates believed they had good reasons for adopting the stance that they did and we are equally sure that they thought long and hard about whether they were doing the right thing. But we are bound to record our clear view that they were wrong and that there could be no reason for not continuing to take part in an appeal that was still being pursued. ... As it happens, the evidence in this case against the Appellant is so strong that no Special Advocates, however brilliant, could have persuaded us that reasonable suspicion had not been established so that the certification was not justified. Thus the absence of Special Advocates has not prejudiced the Appellant. ...” 56.  SIAC then summarised the open case against the applicant, which was that he had associated with and acted as spiritual adviser to a number of individuals and groups linked with al-Qaeda. He held extreme and fundamentalist views and had been reported as having, in his speeches at a London mosque, given his blessing to the killing of Jews and Americans, wherever they were. SIAC concluded:
“We are satisfied that the Appellant’s activities went far beyond the mere giving of advice. He has certainly given the support of the Koran to those who wish to further the aims of al-Qaeda and to engage in suicide bombing and other murderous activities. The evidence is sufficient to show that he has been concerned in the instigation of acts of international terrorism. But spiritual advice given in the knowledge of the purposes for which and the uses to which it is to be put provides assistance within the meaning of section 21(4) of the 2001 Act.
...
There are a large number of allegations made. We see no point in dealing with them seriatim. We have indicated why we have formed the view that the case made against the Appellant is established. Indeed, were the standard higher than reasonable suspicion, we would have had no doubt that it was established. The Appellant was heavily involved, indeed was at the centre in the United Kingdom of terrorist activities associated with al-Qaeda. He is a truly dangerous individual and these appeals are dismissed.” 57.  The ninth applicant is Algerian, born in 1972. In 1991 he left Algeria for Afghanistan, where he taught Arabic in a refugee camp. He claimed asylum in the United Kingdom in 1993. In 1994 he was granted leave to remain for four years and in 2000 he was granted indefinite leave to remain, on the basis that he was to be regarded as a refugee. On four occasions, the last in May 1998, the applicant was arrested and released without charge. The first three arrests related to credit card fraud. The arrest in May 1998 related to alleged terrorist activities and the applicant was subsequently paid compensation by the police for false arrest. 58.  The ninth applicant was certified by the Secretary of State and made the subject of a deportation order on 22 April 2002. He was detained on the same day. According to the evidence of one of the witnesses for the Secretary of State, he was not certified, with the other applicants, in December 2001 because one of his files had been lost. 59.  In its judgment of 29 October 2003, SIAC noted that the allegations against the ninth applicant were that he was an active supporter of GSPC and had raised considerable sums of money for it through fraud. There was evidence that the applicant had in the past been found, by customs officers, attempting to enter the United Kingdom by ferry with large amounts of cash and that he had close links with others who had been convicted of credit card fraud. SIAC held that evidence of involvement in fraud did not establish involvement in terrorism. However, it noted that the applicant had been present at a camp in Dorset in the company of the fifth applicant and a number of others suspected of being GSPC supporters and that a telephone bill had been found at his house at the time of his arrest in the name of Yarkas, who had been arrested in Spain in November 2001 due to his alleged links with al-Qaeda. The applicant had given evidence but had not been a convincing witness and had not given a credible explanation for the foregoing. The closed evidence supported the Secretary of State’s allegations and SIAC therefore dismissed the applicant’s appeal against certification. 60.  In its review judgments of 2 July 2004 and 15 December 2004, SIAC held that the certificate was properly maintained. 61.  The tenth applicant is an Algerian national. Following a bomb explosion in Algeria, his left hand was amputated at the wrist and his right arm was amputated below the elbow. In 1999 he travelled to the United Kingdom, via Abu Dhabi and Afghanistan, and claimed asylum. His claim was refused on 27 February 2001. He was then in custody, having been arrested on 15 February 2001 and charged with possession of articles for suspected terrorist purposes, conspiracy to defraud and conspiracy to make false instruments. At the time of his arrest he was found to have in his possession approximately forty blank French driving licences, identity cards and passports, a credit card reader, laminators and an embossing machine. The charges were not, however, proceeded with and he was released on 17 May 2001. 62.  On 14 January 2003 the Secretary of State issued a certificate against him under section 21 of the 2001 Act and he was taken into detention. A deportation order was made against him on the same day. 63.  In its judgment of 27 January 2004, SIAC noted that the essence of the case against the tenth applicant was that since his arrival in the United Kingdom he had been closely associated with a network of extremists formerly led by Abu Doha (see paragraph 26 above). In particular, it was alleged that he had provided logistical support in the form of false documentation and money raised through credit card fraud. He had spent a lot of time at the Finsbury Park Mosque, a known centre of Islamist extremism, and was alleged to have attended a meeting there in June 2001 at which threats were made against the G8 summit in Genoa.
The applicant submitted a written statement on 28 June 2003 in which he denied the allegations against him. He did not, however, participate in the hearing of his appeal, as SIAC explained in its judgment:
“He was, said [his counsel], a genuine refugee, a member of no organisation or group and not involved in terrorism or in advocating terrorism. He had no knowledge of any planned terrorist attacks and could not understand why the accusations had been made against him. He had seen none of the underlying material and had no means of challenging it. In effect, he could do no more than assert that it could not justify the conclusion that he was an international terrorist within the meaning of the Act since he was not. He had had read to him the decisions of [SIAC] in the previous appeals. Given the relevance which was placed on the closed material and the statutory test applicable, he felt that the result was a foregone conclusion. He did not wish in participating in the appeal to give an impression which was false that he could deal with the matters which were being relied on against him. He had no confidence in the proceedings. Accordingly he would take no active part in them beyond the statement which [his counsel] made on his behalf.
He did not withdraw his appeal. While we appreciate the handicap under which he and indeed all the Appellants labour, we wish to make it clear that no appeal is a foregone conclusion. We have to and we do consider the evidence put before us, whether open or closed, with care because we recognise that the result is detention for an unspecified period without trial. While we recognise that the Special Advocate has a difficult task when he has and can obtain no instructions on closed material, he is able to test evidence from the Security Service and to draw our attention to material which assists the Appellant’s case.”
SIAC found that there was ample evidence to support the view that the applicant was involved in fraudulent activities. The evidence before it, most of it closed, was sufficient to establish that he was doing it to raise money for terrorist causes and to support those involved in terrorism. It therefore dismissed the appeal against certification. 64.  SIAC reached similar decisions in its review judgments of 4 August 2004 and 16 February 2005. In the latter judgment, it noted that although the applicant had been transferred to Broadmoor Secure Mental Hospital because of mental health problems, that made no difference to the assessment of the risk to national security which he would pose if released. 65.  The eleventh applicant is an Algerian national. He entered the United Kingdom in February 1998, using a false Italian identity card, and claimed asylum the following week. While his claim was pending, in July 2001, he travelled to Georgia using a false French passport and was deported back to the United Kingdom, where he was informed that his travel outside the United Kingdom had terminated his asylum claim. He made a second claim for asylum, which was refused on 21 August 2001. The applicant absconded. He was arrested on 10 October 2001 and held in an immigration detention centre, from which he absconded in February 2002. He was rearrested on 19 September 2002 and detained at Belmarsh Prison under immigration law provisions. 66.  On 2 October 2003 the Secretary of State certified him as an international terrorist under section 21 of the 2001 Act and made a deportation order against him on grounds of national security. 67.  In its judgment of 12 July 2004, dismissing the eleventh applicant’s appeal against certification, SIAC set out the open case against him. It was alleged that he was an established and senior member of the Abu Doha group (see paragraph 26 above). In July 2001 he had attempted to travel to Chechnya and, when arrested by the Georgian police, he had been found in possession of telephone numbers associated with a senior member of the Abu Doha group and a named member of GSPC, who was known to be involved in fund-raising for the Chechen Mujahaddin. He was alleged to have provided money and logistical support to a North African extremist Islamist network based in Pakistan and Afghanistan, with links to al-Qaeda, and to have assisted members of the Abu Doha group in travelling to Afghanistan, Pakistan and Chechnya. He had lived at the Finsbury Park Mosque for over a year in 1999/2000. He was very security-conscious and during a trip to St Albans in September 2001 he had taken measures to avoid being followed. When he was arrested in September 2002 he was found in possession of a false Belgian passport bearing the photograph of a senior member of the Abu Doha group. He was alleged to have been heavily involved in the supply of false documents and the fraudulent use of cheque books and credit cards. 68.  The applicant filed a written statement in which he denied being an international terrorist. He admitted that he had travelled to Afghanistan in 1999 and that he had attempted to go to Chechnya in 2001, but claimed that his interest in these countries was no more than that shown by many devout Muslims. He refused to participate in the hearing of his appeal or to be represented by a lawyer, in protest at the fundamental unfairness of the procedure. In view of the applicant’s position, the special advocates decided that his interests would best be served if they refrained from making submissions on his behalf or asking questions of the witnesses in the closed session. 69.  In dismissing the applicant’s appeal, SIAC held as follows:
“We recognise the difficulties faced by an Appellant who only sees only the open material and can understand [the eleventh applicant’s] perception that the procedures are unfair. However, each case will turn upon its own individual facts, and it would be wrong to give the impression, which [his solicitor] sought to do, that this particular Appellant had been placed in a position where he was prevented by reason of the procedures under the Act from mounting an effective defence in response to the case made against him.
We have summarised the information made available to [the eleventh applicant] at the various stages of the procedure ... and [his] response to this information in his written statement. While some of the assessments in the open material can fairly be described as general assertions unsupported by any documentary evidence, in response to which [the eleventh applicant] would not have been able to give any more than an equally general denial, it is clear that in respect of other assessments [he] was provided with a great deal of detailed information: names, dates, places and supporting documents.
[The eleventh applicant] is in the best position to give an account of his whereabouts and activities since he first claimed asylum in 1998. His written statement is significant not so much for what it says, as for what it does not say. To take one example: the visit to St Albans and the photo-booth where [the eleventh applicant] says that the Respondent’s specific assertion is ‘completely wrong’ ... [The eleventh applicant] has not denied that he went to St Albans. He knows who accompanied him and why they went there. He has not explained why they went there, nor has he identified his companion, despite having been provided with the photographs taken during the surveillance operation. ...”
SIAC continued by noting the inconsistencies in the applicant’s various accounts of his trips to Afghanistan, Georgia and Dubai and his failure to deal with the Secretary of State’s allegations that he had associated with various members of the Abu Doha group, identified by name. SIAC continued:
“The matters referred to ... are not an exhaustive list, merely the most obvious examples of the way in which [the eleventh applicant’s] written statement fails to deal with the open case made against him. Given the unsatisfactory nature of the statement we do not feel able to give any significant weight to the general denials contained within it ... We have dealt with these matters in some detail because they are useful illustrations of the extent to which [the eleventh applicant] would have been able to answer the case against him, if he had chosen to do so. While we do not draw any adverse inference from [his] failure to give evidence, or otherwise participate in the hearing of his appeal, we do have to determine his appeal on the evidence and we are left with the position that there has been no effective challenge by way of evidence, cross-examination or submission to the open material produced by the Respondent.
...
The standard of proof prescribed by section 25(2) of the 2001 Act is relatively low: are there reasonable grounds for belief or suspicion. As explained above, we are satisfied that this low threshold is easily crossed on the basis of the open material alone. If the totality of the material, both open and closed, is considered, we have no doubt that [the eleventh applicant] was a senior, and active, member of the Abu Doha group as described in the Respondent’s evidence.” 70.  The detained applicants were all initially detained at Belmarsh Prison in London. The sixth applicant was transferred to Woodhill Prison and the first, seventh and tenth applicants were transferred to Broadmoor Secure Mental Hospital. 71.  They were held in prison under the same regime as other standard-risk Category A prisoners, which was considered the appropriate security classification on the basis of the risk they posed. They were allowed visitors, once those visitors had been security-cleared, and could associate with other prisoners, make telephone calls and write and receive letters. They had access to an imam and to their legal representatives. They had the same level of access to health care, exercise, education and work as any other prisoner of their security ranking.
Following a recommendation of the inspector appointed under the 2001 Act to review the detention regime, the Government created a Special Unit at Woodhill Prison to house the 2001 Act detainees. The Unit, which was refurbished in consultation with the detained applicants and their representatives and had a specially selected and trained staff, would have allowed for a more relaxed regime, including more out-of-cell time. The applicants, however, chose not to move to the Unit, a decision which the inspector found regrettable. 72.  The first applicant, who alleged a history of ill-treatment in Israeli detention and who had first been treated for depression in May 1999, suffered a severe deterioration in his mental health while detained in Belmarsh Prison. He was transferred to Broadmoor Secure Mental Hospital in July 2002. 73.  The seventh applicant reported a family history of psychiatric disorder and had experienced depression as an adolescent. He claimed to suffer increasingly throughout his detention from depression, paranoia and auditory hallucinations. He attempted suicide in May 2004 and was transferred to Broadmoor Secure Mental Hospital on 17 November 2004. 74.  The tenth applicant, a double amputee, claimed to have been detained and tortured in Algeria. He suffered a deterioration in his physical and mental health in Belmarsh Prison. He went on hunger strike in May/June 2003 and refused to use the prostheses which had been issued to him or to cooperate with his nurses. Early in November 2003, the prison authorities withdrew his nursing care. His legal representatives applied for judicial review of this decision and in December 2003 nursing care was resumed following the order of the Administrative Court. On 1 November 2004 the tenth applicant was transferred to Broadmoor Secure Mental Hospital. 75.  The European Committee for the Prevention of Torture and Inhuman or Degrading Treatment or Punishment (CPT) visited the detained applicants in February 2002 and again in March 2004, and made a number of criticisms of the conditions in which the detained applicants were held. The Government rejected these criticisms (see paragraphs 101-02 below). 76.  In October 2004, at the request of the applicants’ legal representatives, a group of eight consultant psychiatrists prepared a Joint Psychiatric Report on the detained applicants, which concluded:
“The detainees originate from countries where mental illness is highly stigmatised. In addition, for devout Muslims there is a direct prohibition against suicide. This is particularly significant given the number who have attempted or are considering suicide. All of the detainees have serious mental health problems which are the direct result of, or are seriously exacerbated by, the indefinite nature of the detention. The mental health problems predominantly take the form of major depressive disorder and anxiety. A number of detainees have developed psychotic symptoms, as they have deteriorated. Some detainees are also experiencing PTSD [post-traumatic stress disorder] either as a result of their pre-migration trauma, the circumstances around their arrest and imprisonment or the interaction between the two.
Continued deterioration in their mental health is affected also by the nature of, and their mistrust in, the prison regime and the appeals process as well as the underlying and central factor of the indefinite nature of detention. The prison health-care system is unable to meet their health needs adequately. There is a failure to perceive self-harm and distressed behaviour as part of the clinical condition rather than merely being seen as manipulation. There is inadequate provision for complex physical health problems.
Their mental health problems are unlikely to resolve while they are maintained in their current situation and given the evidence of repeated interviews it is highly likely that they will continue to deteriorate while in detention.
The problems described by the detainees are remarkably similar to the problems identified in the literature examining the impact of immigration detention. This literature describes very high levels of depression and anxiety and eloquently makes the point that the length of time in detention relates directly to the severity of symptoms and that it is detention per se which is causing these problems to deteriorate.” 77.  For the purposes of the present proceedings, the Government requested a Consultant Psychiatrist, Dr J., to comment on the above Joint Psychiatric Report. Dr J. was critical of the methodology and conclusions of the authors of the Joint Report. In particular, he wrote (references to other reports omitted):
“I would comment that I find many of the assertions made do not bear close inspection. For example in the case of [the first applicant] it was my finding after a careful and detailed assessment that his mental state after imprisonment and then detention in Broadmoor Hospital was, overall, no worse and arguably no better than it had been before he was arrested. Nor do his records suggest initial improvement followed by deterioration in Broadmoor Hospital. I found he deteriorated in HMP Belmarsh [Prison] because he chose to go on hunger strike and that he had a fluctuating course in Broadmoor Hospital despite agreeing to eat, his histrionic behaviour in both places being essentially the same. In his case I found the diagnosis to be one of personality disorder, diagnoses of major depressive disorder, psychosis and PTSD not being sustainable. Moreover, it was my finding that his frequent self-harming was indeed manipulative.
...
I am not alone in finding the diagnoses claimed by the authors of this report to be mistaken and have drawn attention in my own report to the scepticism of some others who have reported on [the first and seventh applicants]. It is not the case therefore that there is the consensus of opinion claimed in the report and I note that in both the cases I assessed [the first and seventh applicants], their so-called psychotic symptoms claimed by some reporters and said not to be present before they were detained, were in fact present before they were arrested.
An issue I find to be of the greatest concern relates to the tacit acceptance of information gained by self-report. It appears to be accepted by the authors of the report, for example, that three of the detainees had been the victims of detention and torture and all felt themselves seriously threatened prior to migration. Nowhere have I seen any evidence to corroborate these claims or indeed any attempt to check them. As it is the case that immigrants and asylum-seekers need to justify their attempts to gain entry to another country, is it not possible or even probable that some may not always be entirely truthful in what they claim about their past experiences or their current symptoms? Where alleged terrorists are concerned it should be borne in mind that they have denied such allegations in spite of the open and closed evidence against them, which has been considered at the highest level. Surely this should raise doubts about their truthfulness?” 78.  On 20 January 2004, SIAC decided that it should, in principle, grant bail to the fifth applicant. The Secretary of State attempted to appeal against this decision but was informed by the Court of Appeal in an interim decision dated 12 February 2004 that it had no jurisdiction to entertain an appeal. 79.  SIAC explained its reasons for granting bail in greater detail in a judgment dated 22 April 2004. It held that under the 2001 Act it had a power to grant bail only in an exceptional case, where it was satisfied that if bail were not granted the detainee’s mental or physical condition would deteriorate to such an extent as to render his continued detention a breach of Article 3 of the Convention on grounds of inhumanity, or Article 8 on grounds of disproportionality. 80.  SIAC noted that there had been concerns about the fifth applicant’s mental health among prison staff from May 2002, although these concerns had not been communicated to his legal representatives. In December 2003 he had suffered a serious relapse into severe depression with psychotic symptoms, including auditory hallucinations and suicide ideation. A number of psychologists and psychiatrists had examined him, at the request of his legal representatives and at the initiative of the Home Office, and had agreed that he was seriously ill and that his mental health would be likely to improve if he were allowed to go home. SIAC concluded:
“We do not think that the threshold has been crossed so that there is a breach of [the fifth applicant’s] human rights. The jurisprudence of the [European Court of Human Rights] emphasises the high threshold which must be crossed and that detention is unlikely to be regarded as disproportionate unless it at least verges on treatment which would constitute a breach of Article 3. But we are satisfied that, if he were not released, there would be such a breach. To permit someone to reach a state whereby he requires treatment in a special hospital or continuous care and attention to ensure he does not harm himself can constitute a breach of Article 8, unless perhaps there is no possible alternative to detention, and probably of Article 3. As we have said, we do not have to wait until that situation exists. Provided that we are persuaded, as we are, that the conditions we impose are sufficient to minimise the risk to the security of the State if [the fifth applicant] is released, we can act as we have.
We must emphasise that the grant of bail is exceptional. We are only doing so because the medical evidence is all one way and the detention has caused the mental illness which will get worse. ...” 81.  The fifth applicant was, therefore, released on bail on 22 April 2004 on conditions amounting to house arrest. He was not permitted to leave his home address and had to wear an electronic tag at all times. He had no Internet access and a telephone link to the Security Service only. He was required to report by telephone to the Security Service five times a day and allow its agents access to his home at any time. He was not permitted contact with any person other than his wife and child, legal representative and a Home Office-approved doctor or see any visitor except with prior Home Office approval. 82.  The declaration of incompatibility made by the House of Lords on 16 December 2004, in common with all such declarations, was not binding on the parties to the litigation (see paragraph 94 below). The applicants remained in detention, except for the second and fourth applicants who had elected to leave the United Kingdom and the fifth applicant who had been released on bail on conditions amounting to house arrest. Moreover, none of the applicants was entitled, under domestic law, to compensation in respect of their detention. The applicants, therefore, lodged their application to the Court on 21 January 2005. 83.  At the end of January 2005, the Government announced their intention to repeal Part 4 of the 2001 Act and replace it with a regime of control orders, which would impose various restrictions on individuals, regardless of nationality, reasonably suspected of being involved in terrorism. 84.  Those applicants who remained in detention were released on 10‑11 March 2005 and immediately made subject to control orders under the Prevention of Terrorism Act 2005, which came into effect on 11 March 2005. 85.  The Government withdrew the derogation notice on 16 March 2005. 86.  On 11 August 2005, following negotiations commenced towards the end of 2003 to seek from the Algerian and Jordanian governments assurances that the applicants would not be ill-treated if returned, the Government served notices of intention to deport on the fifth, sixth, seventh, eighth, ninth, tenth and eleventh applicants. These applicants were taken into immigration custody pending removal to Algeria (the fifth, sixth, seventh, ninth, tenth and eleventh applicants) and Jordan (the eighth applicant). On 9 April 2008 the Court of Appeal ruled that the eighth applicant could not lawfully be extradited to Jordan, because it was likely that evidence which had been obtained by torture could be used against him there at trial, in flagrant violation of his right to a fair trial. At the date of adoption of the present judgment, the case was pending before the House of Lords.
