8.  The applicants have been indicted on various charges of terrorism in the United States of America. They are the subject of three separate sets of criminal proceedings in the United States federal courts. The first set concerns the first applicant, Mr Ahmad, and the third applicant, Mr Ahsan. The second set of proceedings concerns the second applicant, Mr Aswat, and the fourth applicant, Abu Hamza. The third set of proceedings concerns the fifth applicant, Mr Bary, and the sixth applicant, Mr Al Fawwaz. 9.  The details of each indictment are set out below. On the basis of each indictment, the United States Government requested each applicant’s extradition from the United Kingdom. Each applicant then contested his proposed extradition in separate proceedings in the English courts. 10.  The indictment against the first applicant was returned by a Federal Grand Jury sitting in Connecticut on 6 October 2004. It alleges the commission of four felonies between 1997 and August 2004: conspiracy to provide material support to terrorists; providing material support to terrorists; conspiracy to kill, kidnap, maim or injure persons or damage property in a foreign country; and money laundering. On 28 June 2006, a similar indictment was returned against the third applicant, save that the charge of money laundering was not included. For both indictments, the material support is alleged to have been provided through a series of websites, one of whose servers was based in Connecticut. The charge of conspiracy to kill, kidnap, maim or injure persons or damage property in a foreign country is based on two allegations: first, that the websites exhorted Muslims to travel to Chechnya and Afghanistan to defend those places; and second, that classified US Navy plans relating to a US naval battle group operating in the Straits of Hormuz in the Persian Gulf had been sent to the website. The plans are alleged to have discussed the battle group’s vulnerability to terrorist attack. 11.  The indictment against the fourth applicant was returned on 19 April 2004 by a Federal Grand Jury sitting in the Southern District of New York. It charges him with eleven different counts of criminal conduct. These cover three sets of facts. 12.  The first group of charges relates to the taking of sixteen hostages in Yemen in December 1998, four of whom died during a rescue mission conducted by Yemeni forces. The indictment charges the fourth applicant with conspiracy to take hostages and hostage taking and relates principally to his contact with the leader of the hostage takers, Abu Al-Hassan, before and during the events in question. 13.  The second group of charges relates to the conduct of violent jihad in Afghanistan in 2001. The indictment alleges that the fourth applicant provided material and financial assistance to his followers and arranged for them to meet Taliban commanders in Afghanistan. In this respect, four counts of the indictment charge him with providing and concealing material support and resources to terrorists and a foreign terrorist organisation and conspiracy thereto. A further count charges him with conspiracy to supply goods and services to the Taliban. 14.  The third group of charges relates to a conspiracy to establish a jihad training camp in Bly, Oregon between June 2000 and December 2001. Two counts charge the fourth applicant with providing and concealing material support and resources to terrorists and providing material support and resources to a foreign terrorist organisation (Al Qaeda); a further two counts charge him with conspiracy to the main two counts. 15.  On 12 September 2005, a superseding indictment was returned which named and indicted the second applicant as the fourth applicant’s alleged co-conspirator in respect of the Bly, Oregon charges (thus charging the second applicant with the same four counts as those faced by the fourth applicant in respect of the Bly, Oregon conspiracy). On 6 February 2006 a second superseding indictment was returned, which indicted a third man, Oussama Abdullah Kassir, as a co-conspirator in respect of the Bly, Oregon charges. 16.  Mr Kassir was extradited to the United States from the Czech Republic in September 2007. On 12 May 2009, Mr Kassir was convicted on five counts relating to the Bly, Oregon jihad camp conspiracy. He was also convicted of a further six counts relating to the operation of terrorist websites. On 15 September 2009, after submissions from Mr Kassir and his defence counsel, the trial judge sentenced Mr Kassir to the maximum permissible sentence on each count. As a life sentence was the maximum permissible sentence on two of the counts, Mr Kassir had effectively been sentenced to a term of life imprisonment. 17.  In 1999 a Federal Grand Jury sitting in the Southern District of New York returned an indictment against Osama bin Laden and twenty other individuals, including the applicants, inter alia alleging various degrees of involvement in or support for the bombing of the United States embassies in Nairobi and Dar es Salaam in 1998. 18.  The fifth applicant is charged with four counts: conspiracy to kill United States nationals, conspiracy to murder, conspiracy to destroy buildings and property, and conspiracy to attack national defence utilities. 19.  The sixth applicant is charged with two hundred and eighty-five counts of criminal conduct, including over two hundred and sixty-nine counts of murder. 20.  The first applicant was arrested in London on 5 August 2004.  On 23 March 2005, the United States Embassy in London issued Diplomatic Note No. 25. Where relevant, the note provides:
“Pursuant to Article IV of the Extradition Treaty Between the Government of the United States and the Government of the United Kingdom of Great Britain and Northern Ireland, the Government of the United States hereby assures the Government of the United Kingdom that the United States will neither seek the death penalty against, nor will the death penalty be carried out, against Babar Ahmad upon his extradition to the United States.
The Government of the United States further assures the Government of the United Kingdom that upon extradition to the United States, Babar Ahmad will be prosecuted before a Federal Court in accordance with the full panoply of rights and protections that would otherwise be provided to a defendant facing similar charges.
Pursuant to his extradition, Babar Ahmad will not be prosecuted before a military commission, as specified in the President’s Military Order of November 13, 2001; nor will he be criminally prosecuted in any tribunal or court other than a United States Federal Court; nor will he be treated or designated as an enemy combatant...” 21.  Similar Diplomatic Notes were provided in respect of the other applicants in the course of their respective extradition proceedings. 22.  At the extradition hearing before the Senior District Judge, the first applicant argued, inter alia, that, notwithstanding the Diplomatic Note, the risk of the death penalty being imposed remained since he could be tried on a superseding indictment. He further argued that he remained at risk of being designated as an “enemy combatant” pursuant to United States Military Order No. 1 and that he remained at risk of extraordinary rendition to a third country. He also argued that there was a substantial risk that he would be subjected to special administrative measures whilst in detention in a federal prison, which could involve, among other measures, solitary confinement in violation of Article 3 and restrictions on communication with lawyers in violation of Article 6 of the Convention. 23.  In a decision given on 17 May 2005, the Senior District Judge ruled that the extradition could proceed and that, inter alia, the first applicant’s extradition would not be incompatible with his rights under the Convention. The Senior District Judge found that, on the basis of the Diplomatic Note, there was no risk that the death penalty would be imposed, that the applicant would be designated as an enemy combatant, or subjected to extraordinary rendition. The Senior District Judge found the application of special administrative measures to be the greatest ground for concern but concluded that, having regard to the safeguards accompanying such measures, there would be no breach of the applicant’s Convention rights. 24.  The Senior District Judge concluded as follows:
“This is a difficult and troubling case. The [first applicant] is a British subject who is alleged to have committed offences which, if the evidence were available, could have been prosecuted in this country. Nevertheless the Government of the United States are entitled to seek his extradition under the terms of the Treaty and I am satisfied that none of the statutory bars [to extradition] apply.”
Accordingly, he sent the case to the Secretary of State for his decision as to whether the first applicant should be extradited. 25.  On 15 November 2005, the Secretary of State (Mr Charles Clarke) ordered the first applicant’s extradition. The first applicant appealed to the High Court (see paragraphs 29 et seq. below). 26.  On 7 August 2005 the second applicant was arrested in the United Kingdom, also on the basis of an arrest warrant issued under section 73 of the Extradition Act 2003, following a request for his provisional arrest by the United States. 27.  The Senior District Judge gave his decision in the second applicant’s case on 5 January 2006. He concluded that none of the bars to extradition applied, and sent the case to the Secretary of State for his decision as to whether the second applicant should be extradited. 28.  On 1 March 2006, the Secretary of State ordered his extradition. The second applicant appealed to the High Court. 29.  The first and second applicants’ appeals were heard together. In its judgment of 30 November 2006, the High Court rejected their appeals. The High Court found that, according to the case-law of this Court, solitary confinement did not in itself constitute inhuman or degrading treatment. Applying that approach, the evidence before it – which included an affidavit from a United States Department of Justice official outlining the operation of special administrative measures – did not “begin to establish a concrete case under Article 3”. 30.  The first and second applicants applied for permission to appeal to the House of Lords. This was refused by the House of Lords on 6 June 2007. 31.  The United States formally requested the extradition of the third applicant on 15 September 2006. The extradition hearing started on 20 November 2006 on which date the Senior District Judge determined that the third applicant was accused of offences for which he could be extradited. The case was then adjourned for evidence and argument, inter alia as to whether the third applicant’s extradition would be compatible with his Convention rights. The hearing resumed on 19 March 2007. By now bound by the High Court’s judgment in respect of the first and second applicants, the Senior District Judge found that the third applicant’s extradition would be compatible with the Convention. He accordingly sent the case to the Secretary of State for his decision as to whether the third applicant should be extradited. 32.  On 14 June 2007, the Secretary of State (Dr John Reid) ordered that the extradition could proceed. The third applicant appealed against this decision to the High Court and also sought judicial review of the alleged failure of the Director of Public Prosecutions for England and Wales (“the DPP”) to consider whether he should instead be tried in the United Kingdom. He relied on guidance agreed between the Attorney General of the United States and his United Kingdom counterparts for handling criminal cases with concurrent jurisdiction between the United Kingdom and the United States (see paragraph 63 below). 33.  On 10 April 2008 the High Court dismissed the third applicant’s human rights appeal, relying on its ruling in respect of the first and second applicants. In the same judgment, it also dismissed his application for judicial review, finding that the guidance had no application to the third applicant’s case. The guidance only applied to cases where there had been an investigation of the case in the United Kingdom and the DPP had been seized of the case as prosecutor. 34.  On 14 May 2008 the High Court refused to certify a point of law of general public importance which ought to be considered by the House of Lords and also refused leave to appeal to the House of Lords. 35.  The United States requested the fourth applicant’s extradition on 21 May 2004. He was arrested in London on 5 August 2004. 36.  The extradition proceedings were adjourned when he was convicted of offences in the United Kingdom and sentenced to seven years’ imprisonment (see Mustafa (Abu Hamza) v. the United Kingdom (no. 1) (dec.), no. 31411/07, 18 January 2011). The extradition proceedings resumed when the criminal appeals process was concluded.
a.  The District Court proceedings 37.  When the case came before the Senior District Judge for his decision as to whether the extradition could proceed, the fourth applicant argued, inter alia, that his extradition would give rise to a real risk of a violation of Article 3 of the Convention since he would be likely to be detained in a “supermax” detention facility such as the United States Penitentiary, Administrative Maximum, Florence, Colorado (“ADX Florence”). In this connection, he also relied on his poor health, specifically his type-two diabetes, his high blood pressure, the loss of sight in his right eye and poor vision in his left, the amputation of both his forearms (which frequently led to infections through abrasions), psoriasis on much of his body, hyperhydrosis (excessive sweating). A violation of Article 3, he claimed, would also result from the imposition of special administrative measures. 38.  The Senior District Judge, in his ruling of 15 November 2007, rejected all these submissions. In respect of detention at ADX Florence the Senior District Judge found that the fourth applicant’s poor health and disabilities would be considered and, at worst, he would only be detained there for a relatively short period of time. The Senior District Judge was also not satisfied that special administrative measures would be applied to the fourth applicant but even if they were, he was bound by the ruling of the High Court in respect of the first and second applicants. Having concluded that none of the bars to extradition applied, the Senior District Judge sent the case to the Secretary of State (Ms Jacqui Smith) for her decision as to whether the fourth applicant should be extradited. She ordered his extradition on 7 February 2008. The fourth applicant appealed to the High Court against the Secretary of State’s decision and against the decision of the Senior District Judge.
b.  The High Court proceedings 39.  Before the High Court, the fourth applicant again relied on his submission that conditions of detention at ADX Florence would not comply with Article 3. He also argued that the length of the possible sentence he faced in the United States would be contrary to Article 3 of the Convention. 40.  The High Court gave its judgment on 20 June 2008, dismissing the fourth applicant’s appeal. In relation to Article 3, the High Court found that, if convicted, the fourth applicant would be sentenced to very lengthy terms of imprisonment and that, in all likelihood, a life sentence would be imposed. It found that this, of itself, would not constitute a breach of Article 3. On the question of the compatibility of detention at ADX Florence with Article 3, the High Court relied in particular on the understanding of the prison warden, Mr Robert Wiley, to the effect that if, after a full medical evaluation, it was determined that the fourth applicant could not manage his activities of daily living, it would be highly unlikely that he would be placed at ADX Florence rather than at a medical centre. Accordingly, there was no risk of a violation of Article 3 on this ground. However, the High Court added:
“[T]he constitution of the United States of America guarantees not only ‘due process’, but it also prohibits ‘cruel and unusual punishment’. As part of the judicial process prisoners, including those incarcerated in Supermax prisons, are entitled to challenge the conditions in which they are confined, and these challenges have, on occasions, met with success.
...
We should add that, subject to detailed argument which may be advanced in another case, like Judge Workman [the Senior District Judge], we too are troubled about what we have read about the conditions in some of the Supermax prisons in the United States. Naturally, the most dangerous criminals should expect to be incarcerated in the most secure conditions, but even allowing for a necessarily wide margin of appreciation between the views of different civilised countries about the conditions in which prisoners should be detained, confinement for years and years in what effectively amounts to isolation may well be held to be, if not torture, then ill treatment which contravenes Article 3. This problem may fall to be addressed in a different case.” 41.  The fourth applicant then applied to the High Court for a certificate of points of law of general public importance and for leave to appeal to the House of Lords. On 23 July 2008, the High Court refused both applications. 42.  The United States Government requested the fifth and sixth applicants’ extradition from the United Kingdom in July 1999 and September 1998 respectively.
a.  The initial extradition proceedings 43.  At his committal hearing before the District Court, the sixth applicant contended that extradition was only permitted within the terms of the 1972 USA-UK Extradition Treaty for offences committed within the jurisdiction of the requesting State, and not when that State exercised jurisdiction over extra-territorial offences. He further argued that there was “insufficient evidence” to prove a prima facie case, which was a requirement for extradition under the Treaty. As part of that submission, he sought to have excluded two anonymous witness statements, which had been provided by two informants, “CS/1” and “CS/2”, and which the United States Government relied upon as part of their case against him. It was later revealed that CS/1 was a Mr Al-Fadl who had given evidence against the certain of the applicants’ co-defendants during their trial in the United States. 44.  In his ruling of 8 September 1999, the District Judge rejected these submissions. He considered that the proper construction of the Treaty did not prevent the exercise of jurisdiction over extra-territorial offences. The District Judge was also satisfied that there were real grounds for fear if the identities of CS/1 and CS/2 were revealed. Thus, their anonymous witness statements could be admitted as evidence of a prima facie case. He further found that there was a case for the sixth applicant to answer. 45.  The sixth applicant appealed to the High Court by way of an application for a writ of habeas corpus. The application was dismissed on 30 November 2000. The High Court held that it was necessary to show that the crime in respect of which extradition was sought was alleged to have been committed within the actual territory of the United States. The High Court was, however, satisfied that three overt acts alleged by the United States of America could be relied on to found territorial jurisdiction in the United States, namely (a) the setting up and operating of a secure telephone line in the United States by the sixth applicant through an organisation called MCI; (b) the purchase by the sixth applicant of a satellite phone system in the United States and (c) the issuing, in pursuance of the conspiracy of fatwas and jihads, allegedly prepared with the concurrence of the sixth applicant in the United States and elsewhere. The High Court also found that the District Judge had not erred in admitting the evidence of CS/1 or in finding that there was a prima facie case against the sixth applicant. It did not consider it necessary reach any conclusions in respect of CS/2, judging CS/1’s evidence to be “far the most significant”. 46.  While the sixth applicant’s appeal was pending before the High Court, a committal hearing before the District Court was held in respect of the fifth applicant. The District Judge gave his ruling on 25 April 2000 in which he reaffirmed the rulings he had made in respect of the sixth applicant and found that there was also a prima facie case against the fifth applicant. 47.  The fifth applicant also appealed to the High Court and, on 2 May 2001, a differently constituted court dismissed his appeal. Again the High Court found that the District Judge had not erred in admitting the anonymous evidence of CS/1; that there was sufficient evidence against the fifth applicant for the extradition to proceed, and that the United States had jurisdiction to try him. 48.  Both applicants appealed to the House of Lords. Their appeals were dismissed on 17 December 2001. The House of Lords found unanimously that the High Court had erred in its finding in respect of jurisdiction: it was sufficient that the offence for which extradition was sought was triable within the United States and an equivalent offence would be triable in the United Kingdom. Accordingly, the applicants were liable to extradition to the United States if a prima facie case of conspiracy to murder was established. This was the case for each applicant.
b.  The Secretary of State’s decision, the United States’ assurances, and the fifth and sixth applicants’ appeal to the High Court 49.  Between November 2001 and December 2005 there then followed voluminous representations by the fifth and sixth applicants to the Secretary of State as to why they should not be extradited to the United States. 50.  In the course of these exchanges, on 19 April 2002 the President of the United States designated the sixth applicant as a “specially designated global terrorist”, which had the effect of placing him on a list of persons maintained by the United States Department of the Treasury and available on its website. This was done pursuant to Executive Order 13224 which enables the American assets of any person so designated to be blocked. 51.  Subsequently, on 13 April 2004, the United States Embassy in London issued Diplomatic Note No. 018, which gave assurances that the United States Government would neither seek nor carry out the death penalty against the fifth and sixth applicants. It also gave assurances that they would be tried before a federal court and that they would not be prosecuted by a military commission or designated as enemy combatants. On 18 January 2008, the United States Embassy issued Diplomatic Note No. 002, which assured the United Kingdom Government that, if either applicant were acquitted or completed any sentence imposed or if the prosecution against them were discontinued, the United States authorities would return the men to the United Kingdom, if they so requested. 52.  The Secretary of State (Ms Jacqui Smith) rejected the fifth and sixth applicants’ representations on 12 March 2008. She found that assurances given by the United States in the Diplomatic Note of 13 April 2004 could be relied upon and thus that the fifth and sixth applicants were not at risk of the death penalty, indefinite detention or trial by a military commission. 53.  The fifth and sixth applicants also contended that they would not receive a fair trial in the United States owing to the unavailability of defence witnesses and evidence, adverse publicity, the possible imposition of special administrative measures before trial, and the sixth applicant’s designation as a global terrorist. The Secretary of State found none of these claims amounted to a “flagrant denial of justice” such as would act as a bar to extradition. 54.  The Secretary of State accepted that there was a real possibility that they would be sentenced to life imprisonment if convicted but, relying on the House of Lords’ judgment in R (Wellington) v. Secretary of State for the Home Department (see paragraphs 64–72 below), found that this would not amount to a breach of Article 3 of the Convention. 55.  The Secretary of State also considered that the conditions of the fifth and sixth applicants’ detention in the United States would not violate Article 3 whether they were subjected to “special administrative measures” before trial or detained at ADX Florence after trial. In the fifth applicant’s case, this conclusion was not affected by the fact that he suffered from a recurrent depressive disorder. There was also no risk that either applicant would be tortured, that evidence obtained by torture would be adduced at trial, or that they would be at real risk of torture as a result of extraordinary rendition or refoulement to a third State. 56.  The fifth and sixth applicants sought judicial review of the Secretary of State’s decision in the High Court. Before the High Court the applicants submitted that, if convicted, they would be detained at ADX Florence in violation of Article 3 of the Convention. In rejecting that contention, Lord Justice Scott Baker, delivering the judgment of the court on 7 August 2009, found that the decisions of the United States federal courts in Ajaj, Sattar and Wilkinson v. Austin (see paragraphs 109 and 110 below) demonstrated that there was effective judicial oversight of “supermax” prisons such as ADX. The fifth and sixth applicants would also have the possibility of entering ADX’s “step down program” (see paragraphs 84–88 below). He concluded:
(1)  It is reasonably likely that the claimants will be subjected to [special administrative measures] and will be held in ADX Florence following trial.
(2)  Neither [special administrative measures] (see Ahmad and Aswat) or life without parole (see Wellington) cross the article 3 threshold in the present case. Although near to the borderline the prison conditions at ADX Florence, although very harsh do not amount to inhuman or degrading treatment either on their own or in combination with [special administrative measures] and in the context of a whole life sentence.
(3)  Whether the high article 3 threshold for inhuman or degrading treatment is crossed depends on the facts of the particular case. There is no common standard for what does or does not amount to inhuman or degrading treatment throughout the many different countries in the world. The importance of maintaining extradition in a case where the fugitive would not otherwise be tried is an important factor in identifying the threshold in the present case.
Had the claimants persuaded me that there was no prospect that they would ever enter the step down procedure whatever the circumstances then in my view the article 3 threshold would be crossed. But that is not the case. The evidence satisfies me that the authorities will faithfully apply the criteria [for entry to the program] and that the stringency of the conditions it imposes will continue to be linked to the risk the prisoner presents. Further, there is access to the US courts in the event that the [Federal Bureau of Prisons] acts unlawfully.” 57.  In respect of the fifth applicant’s submission that his recurrent depressive illness would deteriorate if extradited, the High Court considered that, to the extent that this affected his fitness to stand trial, this was a matter for the United States’ authorities and, if he were convicted, the fifth applicant’s mental health would be an important factor in deciding whether he should be sent to ADX Florence. 58.  The High Court also rejected the fifth and sixth applicants’ submissions that they were at real risk of violations of Articles 3, 6 and 14 of the Convention by virtue of the imposition of special administrative measures, relying on its previous judgment in respect of the first and second applicants (see paragraph 29 above). Having regard to the Diplomatic Note of 18 January 2008, the High Court found that there was no real risk of refoulement to Egypt or Saudi Arabia by the United States. The High Court was also satisfied that the United States would honour the assurances it had given in the Diplomatic Note of 13 April 2004. The mere fact that the sixth applicant had been designated as a global terrorist by the President of the United States did not mean he was at risk of a flagrant denial of justice within the meaning of Article 6: the designation added little to what was already known about him; it would be made clear to the jury at any trial what had to be proved as regards the indictment. 59.  The High Court also rejected the applicants’ submission that they should be tried in the United Kingdom, finding that this was neither viable nor appropriate and that any connection with the United Kingdom was “tenuous indeed”. 60.  Although the High Court refused leave to appeal to the United Kingdom Supreme Court, it certified two questions of general public importance. The first question was whether prison conditions at ADX Florence were compatible with Article 3; the second question was whether the relativist approach to Article 3 adopted by the majority of the House of Lords in Wellington should apply where the issue under Article 3 was one of the compatibility of prison conditions with Article 3. 61.  On 16 December 2009, the Supreme Court refused permission to appeal.
II.  RELEVANT DOMESTIC AND INTERNATIONAL LAW ON ARTICLE 3 AND EXTRADTITION 62.  At the material time, the applicable bilateral treaty on extradition was the 1972 UK – USA Extradition Treaty (now superseded by a 2003 treaty). Article IV of the 1972 treaty provided that extradition could be refused unless the requesting Party gave assurances satisfactory to the requested Party that the death penalty would not be carried out. 63.  Guidance for handling criminal cases with concurrent jurisdiction between the United Kingdom and the United States of America was signed on 18 January 2007 by the Attorney General of the United States of America, Her Majesty’s Attorney General and also, for its application to Scotland, by the Lord Advocate. It sets out a series of measures that prosecutors in each State should take to exchange information and consult each other in such cases and to determine issues which arise from concurrent jurisdiction. A case with concurrent jurisdiction is defined as one which has the potential to be prosecuted in both the United Kingdom and the United States. 64.  The United States requested the extradition of Ralston Wellington from the United Kingdom to stand trial in Missouri on two counts of murder in the first degree. In his appeal against extradition, Mr Wellington argued that his surrender would violate Article 3 of the Convention, on the basis that there was a real risk that he would be subjected to inhuman and degrading treatment in the form of a sentence of life imprisonment without parole. 65.  In giving judgment in the High Court ([2007] EWHC 1109 (Admin)), Lord Justice Laws found that there were “powerful arguments of penal philosophy” which suggested that risk of a whole-life sentence without parole intrinsically violated Article 3 of the Convention. He observed:
“The abolition of the death penalty has been lauded, and justified, in many ways; but it must have been founded at least on the premise that the life of every person, however depraved, has an inalienable value. The destruction of a life may be accepted in some special circumstances, such as self-defence or just war; but retributive punishment is never enough to justify it. Yet a prisoner’s incarceration without hope of release is in many respects in like case to a sentence of death. He can never atone for his offence. However he may use his incarceration as time for amendment of life, his punishment is only exhausted by his last breath. Like the death sentence the whole-life tariff is lex talionis. But its notional or actual symmetry with the crime for which it is visited on the prisoner (the only virtue of the lex talionis) is a poor guarantee of proportionate punishment, for the whole-life tariff is arbitrary: it may be measured in days or decades according to how long the prisoner has to live. It is therefore liable to be disproportionate – the very vice which is condemned on Article 3 grounds – unless, of course, the death penalty’s logic applies: the crime is so heinous it can never be atoned for. But in that case the supposed inalienable value of the prisoner’s life is reduced, merely, to his survival: to nothing more than his drawing breath and being kept, no doubt, confined in decent circumstances. That is to pay lip-service to the value of life; not to vouchsafe it.”
However, and “not without misgivings”, he considered that the relevant authorities, including those of this Court, suggested an irreducible life sentence would not always raise an Article 3 issue. 66.  Wellington’s appeal from that judgment was heard by the House of Lords and dismissed on 10 December 2008. Central to the appeal was paragraph 89 of this Court’s judgment in Soering v. the United Kingdom, 7 July 1989, § 89, Series A no. 161, where the Court stated that considerations in favour of extradition:
“.. must also be included among the factors to be taken into account in the interpretation and application of the notions of inhuman and degrading treatment or punishment in extradition cases.” 67.  A majority of their Lordships, Lord Hoffmann, Baroness Hale and Lord Carswell, found that, on the basis of this paragraph, in the extradition context, a distinction had to be drawn between torture and lesser forms of ill-treatment. When there was a real risk of torture, the prohibition on extradition was absolute and left no room for a balancing exercise. However, insofar as Article 3 applied to inhuman and degrading treatment and not to torture, it was applicable only in a relativist form to extradition cases. 68.  Lord Hoffmann, giving the lead speech, considered the Court’s judgment in the case of Chahal v. the United Kingdom, 15 November 1996, § 81, Reports of Judgments and Decisions 1996‑V, in which the Court stated that:
“It should not be inferred from the Court’s remarks [at paragraph 89 of Soering] that there is any room for balancing the risk of ill-treatment against the reasons for expulsion in determining whether a State’s responsibility under Article 3 (art. 3) is engaged.”
Lord Hoffmann stated:
“In the context of Chahal, I read this remark as affirming that there can be no room for a balancing of risk against reasons for expulsion when it comes to subjecting someone to the risk of torture. I do not however think that the Court was intending to depart from the relativist approach to what counted as inhuman and degrading treatment which was laid down in Soering and which is paralleled in the cases on other articles of the Convention in a foreign context. If such a radical departure from precedent had been intended, I am sure that the Court would have said so.”
For Lord Hoffmann, paragraph 89 of Soering made clear that:
“...the desirability of extradition is a factor to be taken into account in deciding whether the punishment likely to be imposed in the receiving state attains the ‘minimum level of severity’ which would make it inhuman and degrading. Punishment which counts as inhuman and degrading in the domestic context will not necessarily be so regarded when the extradition factor has been taken into account.”
He went on to state:
“A relativist approach to the scope of article 3 seems to me essential if extradition is to continue to function. For example, the Court of Session has decided in Napier v Scottish Ministers (2005) SC 229 that in Scotland the practice of ‘slopping out’ (requiring a prisoner to use a chamber pot in his cell and empty it in the morning) may cause an infringement of article 3. Whether, even in a domestic context, this attains the necessary level of severity is a point on which I would wish to reserve my opinion. If, however, it were applied in the context of extradition, it would prevent anyone being extradited to many countries, poorer than Scotland, where people who are not in prison often have to make do without flush lavatories.” 69.  A minority of their Lordships, Lord Scott and Lord Brown, disagreed with these conclusions. They considered that the extradition context was irrelevant to the determination of whether a whole life sentence amounted to inhuman and degrading treatment. They found no basis in the text of Article 3 for such a distinction. Lord Brown also considered that the Court, in Chahal and again in Saadi v. Italy [GC], no. 37201/06, ECHR 2008‑..., had departed from the previous, relativist approach to inhuman and degrading treatment that it had taken in Soering. He stated:
“There is, I conclude, no room in the Strasbourg jurisprudence for a concept such as the risk of a flagrant violation of article 3’s absolute prohibition against inhuman or degrading treatment or punishment (akin to that of the risk of a ‘flagrant denial of justice’). By the same token that no one can be expelled if he would then face the risk of torture, so too no one can be expelled if he would then face the risk of treatment or punishment which is properly to be characterised as inhuman or degrading. That, of course, is not to say that, assuming for example ‘slopping out’ is degrading treatment in Scotland, so too it must necessarily be regarded in all countries (see para 27 of Lord Hoffmann’s opinion)... the Strasbourg Court has repeatedly said that the Convention does not ‘purport to be a means of requiring the contracting states to impose Convention standards on other states’ (Soering, para 86) and article 3 does not bar removal to non-Convention states (whether by way of extradition or simply for the purposes of immigration control) merely because they choose to impose higher levels or harsher measures of criminal punishment.
Nor is it to say that a risk of article 3 ill-treatment, the necessary pre-condition of an article 3 bar upon extradition, will readily be established. On the contrary, as the Grand Chamber reaffirmed in Saadi at para 142:
‘[T]he Court has frequently indicated that it applies rigorous criteria and exercises close scrutiny when assessing the existence of a real risk of ill-treatment . . . in the event of a person being removed from the territory of the respondent State by extradition, expulsion or any other measure pursuing that aim. Although assessment of that risk is to some degree speculative, the Court has always been very cautious, examining carefully the material placed before it in the light of the requisite standard of proof . . . before . . . finding that the enforcement of removal from the territory would be contrary to article 3 of the Convention. As a result, since adopting the Chahal judgment it has only rarely reached such a conclusion.’”
Therefore, for Lord Brown, if a mandatory life sentence violated Article 3 in a domestic case, the risk of such a sentence would preclude extradition to another country. 70.  However, despite these different views, none of the Law Lords found that the sentence likely to be imposed on Mr Wellington would be irreducible; having regard to the commutation powers of the Governor of Missouri, it would be just as reducible as the sentence at issue in Kafkaris v. Cyprus [GC], no. 21906/04, ECHR 2008‑.... All five Law Lords also noted that, in Kafkaris, the Court had only said that the imposition of an irreducible life sentence may raise an issue under Article 3. They found that the imposition of a whole life sentence would not constitute inhuman and degrading treatment in violation of Article 3 per se, unless it were grossly or clearly disproportionate. Lord Brown in particular noted:
“Having puzzled long over this question, I have finally concluded that the majority of the Grand Chamber [in Kafkaris] would not regard even an irreducible life sentence—by which, as explained, I understand the majority to mean a mandatory life sentence to be served in full without there ever being proper consideration of the individual circumstances of the defendant’s case—as violating article 3 unless and until the time comes when further imprisonment would no longer be justified on any ground—whether for reasons of punishment, deterrence or public protection. It is for that reason that the majority say only that article 3 may be engaged.”
Lord Brown added that this test had not been met in Wellington’s case, particularly when the facts of the murders for which he was accused, if committed in the United Kingdom, could have justified a whole life order. However, Lord Brown considered that, in a more compelling case, such as the mercy killing of a terminally ill relative, this Court “might well judge the risk of ill-treatment to be sufficiently real, clear and imminent to conclude that extradition must indeed be barred on article 3 grounds”. 71.  Finally, Lord Hoffmann, Lord Scott, Baroness Hale and Lord Brown all doubted Lord Justice Laws’ view that life imprisonment without parole was lex talionis. Lord Hoffman, Baroness Hale and Lord Brown did not accept his premise that the abolition of the death penalty had been founded on the idea that the life of every person had an inalienable value; there were other, more pragmatic reasons for abolition such as its irreversibility and lack of deterrent effect. Lord Scott rejected the view that an irreducible life sentence was inhuman and degrading because it denied a prisoner the possibility of atonement; once it was accepted that a whole life sentence could be a just punishment, atonement was achieved by the prisoner serving his sentence. 72.  Wellington’s application to this Court was struck out on 5 October 2010, the applicant having indicated his wish to withdraw it (Wellington v. the United Kingdom (dec.), no. 60682/08). 73.  Section 1 of the Canadian Charter of Rights provides that the Charter guarantees the rights and freedoms set out in it “subject only to such reasonable limits prescribed by law as can be demonstrably justified in a free and democratic society.” Section 7 provides:
“Everyone has the right to life, liberty and security of the person and the right not to be deprived thereof except in accordance with the principles of fundamental justice.”
Section 12 provides:
“Everyone has the right not to be subjected to any cruel and unusual treatment or punishment.” 74.  In United States v. Burns [2001] S.C.R. 283, Burns and another (the respondents) were to be extradited from Canada to the State of Washington to stand trial for murders allegedly committed when they were both eighteen. Before making the extradition order the Canadian Minister of Justice had not sought assurances that the death penalty would not be imposed. The Supreme Court of Canada found that the remoteness between the extradition and the potential imposition of capital punishment meant the case was not appropriately considered under section 12 but under section 7. However, the values underlying section 12 could form part of the balancing process engaged under section 7. The extradition of the respondents would, if implemented, deprive them of their rights of liberty and security of person as guaranteed by section 7. The issue was whether such a deprivation was in accordance with the principles of fundamental justice. While extradition could only be refused if it “shocked the conscience” an extradition that violated the principles of fundamental justice would always do so. The court balanced the factors that favoured extradition against those that favoured seeking assurances that the death penalty would not be sought. The latter included the fact that a degree of leniency for youth was an accepted value in the administration of justice, even for young offenders over the age of eighteen. The court concluded that the objectives sought to be advanced by extradition without assurances would be as well served by extradition with assurances. The court held therefore that assurances were constitutionally required by section 7 in all but exceptional cases. 75.  In United States of America v. Ferras; United States of America v. Latty, [2006] 2 SCR 77, the appellants were to be extradited to the United States to face charges of fraud (the Ferras case) or trafficking of cocaine (the Latty case). The appellants in the Latty case had argued that, if extradited and convicted they could receive sentences of ten years to life without parole and this would “shock the conscience”. In dismissing the appeals, the Supreme Court affirmed the balancing approach laid down in Burns to determining whether potential sentences in a requesting state would “shock the conscience”. The harsher sentences the appellants might receive if convicted in the United States were among the factors militating against their surrender but they had offered no evidence or case-law to back up their assertions that the possible sentences would shock the conscience of Canadians. The factors favouring extradition far outweighed those that did not. 76.  Article 7 of the ICCPR where relevant provides that “no one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment.” The Human Rights Committee’s most recent general comment on Article 7 (No. 20, of 10 March 1992) states the Committee’s view that: “States parties must not expose individuals to the danger of torture or cruel, inhuman or degrading treatment or punishment upon return to another country by way of their extradition, expulsion or refoulement.” (see also Chitat Ng v. Canada, CCPR/C/49/D/469/1991, 7 January 1994; A.J.R. v. Australia, CCPR/C/60/D/692/1996, 11 August 1997). 77.  Article 3 § 1 of the 1984 United Nations Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (“UNCAT”) provides:
“No State Party shall expel, return ("refouler") or extradite a person to another State where there are substantial grounds for believing that he would be in danger of being subjected to torture.” 78.  Article 16 § 2 provides:
“The provisions of this Convention are without prejudice to the provisions of any other international instrument or national law which prohibits cruel, inhuman or degrading treatment or punishment or which relates to extradition or expulsion.” 79.  The above guidelines (adopted by the Committee of Ministers on 11 July 2002) contain the following provisions on refoulement and extradition:
“XII.  Asylum, return (‘refoulement’) and expulsion
... 2.  It is the duty of a State that has received a request for asylum to ensure that the possible return (“refoulement”) of the applicant to his/her country of origin or to another country will not expose him/her to the death penalty, to torture or to inhuman or degrading treatment or punishment. The same applies to expulsion.
XIII.  Extradition 3.  Extradition may not be granted when there is serious reason to believe that:
(i)  the person whose extradition has been requested will be subjected to torture or to inhuman or degrading treatment or punishment...” 80.  Article 19 § 2 of the Charter of Fundamental Rights of the European Union provides:
“No one may be removed, expelled or extradited to a State where there is a serious risk that he or she would be subjected to the death penalty, torture or other inhuman or degrading treatment or punishment.” 81.  ADX Florence, a so-called “supermax” prison, is one of a number of detention facilities at the Federal Correctional Complex, Florence, Colorado. The parties have provided a great deal of evidence in respect of conditions of detention at ADX and general facilities at FCC Florence. The applicants have also submitted general evidence on “supermax” prisons and their effects on prisoners. The evidence submitted may be summarised as follows. 82.  The Government submitted a series of declarations, which had been prepared specifically for the present proceedings by officials at FCC/ADX Florence. Thereafter, in reply to a series of questions put by the Court in respect of the number of inmates entering ADX’s “step down program”, two further letters were provided by the United States Department of Justice (see paragraphs 93–97 below).
a.  The declarations 83.  Mr Louis J. Milusnic, the associate warden of ADX, outlined the regime which was in place at the special security unit (H Unit) for inmates who were subjected to special administrative measures. All cells were single occupancy, had natural light and measured 75.5 square feet (approximately 7 square metres). Showers were not in-cell but on a shared range. 84.  Inmates in H Unit were part of the special security unit program, which had three phases that inmates could work through.
In phase one, the “baseline” phase, inmates had two non-legal telephone calls per month, five social visits, access to a commissary list and art and hobby craft items, and escorted shower time three times a week. They had ten hours per week of out-of-cell recreation time (increased from five hours per week in September 2009). As of November 2010, twelve inmates were in phase one.
In phase two, conditions were the same save that three non-legal telephone calls per month were permitted, the commissary list was expanded and inmates were permitted to go to the shower unescorted, five times per week. Eleven inmates were in phase two.
In phase three, group recreation was permitted five days a week (for a minimum of one and a half hours per day, in groups of four) and the number of non-legal telephone calls increased to four. Inmates ate one meal together and engaged in recreational activities together for one and a half hours per day. Access to showers was unrestricted and the commissary list was further expanded. Four inmates, who had all been convicted of terrorist activity, had progressed to phase three.
Advancement through the phases was authorised by a Program Screening Committee, whose six-monthly reviews the inmate attended. The Committee’s task was to determine whether an inmate could function with additional privileges without posing a security or safety risk. Advancement was subject to various factors including good conduct, participation in programmes recommended by the Unit, positive behaviour and respectful conduct and positive overall institutional adjustment. 85.  Recreation alternated daily between outside and inside recreation. Outdoor recreation took place in adjacent individual recreation areas, which allow an inmate full visual access to the recreation yard and other inmates. Conversations could be carried on in a normal tone of voice and most inmates spent the majority of their recreation time talking to other inmates. Each individual outdoor area measured 12 feet by 20 feet (approximately 3.66 metres by 6 metres) and contained pull-up bars and footballs. Individual indoor areas measured 14 feet by 10 feet. Recreation had only been cancelled once in thirteen months for security reasons. 86.  There was no limit on inmates’ correspondence with family members and special administrative measures could be modified to allow correspondence beyond the immediate family. There were also no limits on correspondence with legal representatives and access to a law library for up to two hours at a time. Inmates received a free, daily copy of USA Today. They had access to fifty television channels and seven FM radio channels. They could speak to inmates in adjacent cells using the air ventilation as a voice conduit. They had regular contact with prison staff – a member of the Unit Team visited every inmate every day – and there were visits from medical, education, religious service and psychology staff, including two Arabic speakers. Inmates could request to speak with an officer at any time. 87.  Mr Milusnic also outlined the criteria and procedures for placement at ADX Florence. An inmate either had to: (i) create a security risk at other correctional facilities; or (ii) as a result of his or her status, be unable to be safely housed in the general population of another institution. Referral to ADX was initiated by the staff at the inmate’s current institution. If the warden of that institution, the relevant regional director and the Bureau’s designation centre all concurred, a hearing took place. The inmate was given written notice at least twenty-four hours prior to the hearing. After the hearing, a report with a recommendation was prepared and given to the inmate. The final decision was taken on the basis of the report by an Assistant Director of the Federal Bureau of Prisons, with the possibility of appeal to the chief of the designation centre and thereafter the Office of the General Counsel. 88.  Ms Patricia Rangel is the Unit Manager for the General Population Units at ADX. She provided two declarations.
Her first declaration outlined the Federal Bureau of Prisons procedures for review of the status of inmates. There was an initial classification upon arrival at a new Bureau institution, which took place at a meeting attended by the inmate and which defined, inter alia, the work and educational programmes the inmate would follow, his or her release plans, and security/custody levels. Thereafter, there were six-monthly program reviews (including progress review reports, which were signed by the inmate and the Unit Manager) and more detailed, three-yearly progress reports, which were also made available to the inmate.
In her declaration Ms Rangel also outlined the different levels of security in ADX units and the step down program. The units followed a “stratified” system of housing from General Population Units to the Intermediate, Transitional and Pre-Transfer Units. It would take an inmate a minimum of thirty-six months to work through the system: the minimum stay in each unit was twelve months in a General Population Unit, six months in Intermediate, six in Transitional and twelve in Pre-Transfer. Specific conditions in each unit were as follows.
General Population Unit cells were 87 square feet (8 square metres) plus a sallyport (exit area) of 17 square feet. Showers were within the cells. There was a window with natural lighting and inmates could control the lighting in their cell via a dimmer switch. Lights on the range were switched off at night, but, as in all federal prisons, were briefly turned on for three cell counts during the night. Meals were delivered in-cell. Inmates received two fifteen minute telephone calls and up to five social visits per month. It was possible and permissible for inmates to talk to each other in their cells via the ventilation system or during their out-of-cell recreation.
Inmates had ten hours out-of-cell exercise each week in single-cell recreation areas, some of which were grouped together on large recreation yards. Ms Rangel gave the sizes of the two types of outdoor individualised recreation areas as 240 square feet and 315 square feet (22 and 29 square metres). The size of the indoor areas was 389 square feet (36 square metres). Recreation privileges could be restricted for violations of rules and regulations. Restrictions on outdoor recreation were in three-month increments (three months for a first offence, six for a second offence and so on).
Intermediate Unit cells were 75.5 square feet and did not have a sallyport or shower. There was a window with natural lighting; cell doors faced out onto a range. Inmates were assigned to a group of eight inmates with whom they recreated. Meals were provided to inmates one group at a time, meaning each group was allowed out of their cells to collect their meals in the range. Inmates received three fifteen-minute telephone calls and up to five social visits per month. Showers stalls were on the range, where inmates could shower any time they were out on the range.
Transitional Units had similar conditions to Intermediate Units save that inmates were assigned to groups of sixteen inmates. They received twenty‑one hours of out-of-cell recreation per week in their assigned group on the range or in a large recreation yard. Meals were consumed in groups on the range. Inmates were unrestrained when out of their cells. They received an extra fifteen-minute telephone call per month and could leave the unit unrestrained but escorted to purchase items from the commissary.
The Pre-Transfer Unit was located at another penitentiary at FCC Florence. As in the Intermediate and Transitional Units, inmates ate their meals and recreated within their assigned group. They received twenty-four and a half hours’ out-of-cell recreation time per week, and five visits and three hundred minutes of telephone calls per month.
In the General Population, Intermediate and Transitional Units, access to television, radio and books, contact with prison staff and rules on correspondence were as outlined by Mr Milusnic.
The rules governing the step down program were set out in an “institution supplement”, which had been updated in September 2009. An inmate’s placement in and advancement through the step down program were reviewed every six months, subject to the minimum periods in each unit, set out above, and other criteria such as participation in defined programmes, positive behaviour and overall institutional adjustment. According to the updated supplement, mitigation of the original reason for placement at ADX Florence was no longer a factor which was considered, but the Step Down Screening Committee, which made decisions on advancement, could have regard to the initial reasons for placement at ADX and other safety and security factors. The final decision was one for the Warden. Any negative decision had to be reasoned (unless providing reasons would pose a threat to individual safety or institutional security) and was subject to appeal through the Bureau’s administrative remedy programme. Since the implementation of the updated supplement, there had been a 56% increase in movement of inmates from the four General Population Units to the Intermediate Unit and a 135% increase in movement from the Intermediate to the Transitional Unit. Inmates had also completed the programme and been transferred out of ADX Florence. This included Arab-Muslim inmates. 89.  Mr Christopher B. Synsvoll is the Department of Justice Supervising Attorney at FCC Florence. His declaration outlined the application of special administrative measures. These measures were rare: of 210,307 Federal Bureau of Prison inmates, forty-one were subjected to them; twenty-seven of the forty-one were in H Unit at ADX Florence. Special administrative measures could be challenged through the Bureau’s administrative remedy programme, which led to a review of the need for the measures and which involved consultation with other agencies such as the FBI. This process had, on occasion, led to the modification of certain special administrative measures such as allowing greater communication for inmates with the outside world. 90.  The psychologist assigned to ADX Florence, Dr Paul Zohn, outlined the psychological and psychiatric care available at the prison. The preference was to treat inmates with mental health problems in situ rather than in hospitals where this was possible. Care was provided by one psychiatrist and two psychologists who made regular rounds through the housing units at ADX. Various treatment programs were available and inmates who needed psychotropic medication were seen regularly by a psychiatrist. Contrary to assertions previously made by the applicants, video-conferencing was not ordinarily used to assess an inmate’s mental health. The main mental health disorders such as bipolar affective disorder, depression, post-traumatic stress disorder and schizophrenia would not preclude a designation to ADX and could be managed successfully there. Conditions of confinement were largely determined by security needs and would be modified based on mental illness only if the inmate’s mental status warranted such a change. However, if necessary, inmates could be referred to one of the Bureau’s Psychiatric Referral Centers for acute psychiatric care. Inmates who would be considered “seriously mentally ill” would not be housed at ADX but at a Referral Center. All new inmates at ADX received an initial psychological evaluation and, if necessary, follow-up assessment and treatment planning. Thereafter, the psychological department monitored any treatment needs such as medication or modification to an inmate’s housing, work or program assignment. 91.  The prison chaplain at ADX, Michael S. Merrill, stated that an imam was available to inmates four days a month and would speak to inmates at their cell door. The chaplain had also significantly expanded the Islamic section of the religious library at the prison, which included 158 Arabic language books. There were also 320 videos and DVDs on Islam. The Religious Services Department provided Islamic-faith programming through its closed-circuit television channel, including four to five days of Sunni Muslim programming on Friday and recitations of the Qur’an on Friday and Saturday evenings. Inmates had access to a halal diet; special arrangements were made for meals during Ramadan. Although there could be no formal congregational prayer for any faith group, Muslim inmates could perform the Azan (call to prayer) and the Salat (five daily prayers) in their cells; they could also have access to prayer rugs, prayer oil, prayer beads and religious headgear in their cells. 92.  Ms Roxana Mack, the Assistant Supervisor of Education at ADX, stated that H unit inmates had access to approximately 900 books with no limit on the number of books an inmate could borrow. They had access to a law library for two hours at a time, including access to electronic databases. There were also educational courses.
b.  The Department of Justice’s letters 93.  In the course of proceedings before the Court, the respondent Government were asked to provide information as to:
 (i)  how long inmates in the Special Security Unit program had spent at ADX and how long they had been in each phase of the program;
(ii)  how many inmates were in each phase of the step down program;
(iii)  how long each inmate had spent at ADX and how long they had been in each phase of the program; and
(iv)  how many inmates had completed the program, how long they had spent at ADX and how long they had been in each phase of the program 94.  The questions were forwarded to the United States authorities. By letter dated 26 September 2011, the Department of Justice stated that there were 252 inmates in ADX’s General Population Unit. The Special Security Unit program could house up to 32 inmates. There were 17 inmates in phase I, nine in phase II and six in phase III. For the step down program, 32 inmates were in J Unit, 32 in K Unit and 25 in D/B Unit. The Department of Justice stated that the Bureau of Prisons obligations under United States law prevented disclosure of information as to the length of time inmates had spent at each stage of the two programs. 95.  By letters dated 29 September and 7 October 2011, the Section Registrar clarified that the questions put by the Court were not intended to obtain information on specific inmates but rather to provide meaningful assistance as to: the length of time an inmate was likely to spend at ADX before being admitted to either program; how long he was likely to spend in each phase of either program; and how long he was likely to spend in either program before transfer out of ADX. 96.  On 24 October 2011 the Agent of the Government of the United Kingdom replied, forwarding a letter of the same date from the Department of Justice, which set out the results of a statistical analysis conducted by the Bureau of Prisons. The analysis was based on a random sample of thirty inmates selected from the General Population at ADX and/or each phase of the step down program. On the basis of that sample, an inmate was likely to spend three years at ADX before being admitted to the Step Down or Special Security Unit programs. The likely times in each phase were: nine months in intermediate, eleven months in transition and nine months in pre-transfer. Thus, an inmate was likely to spend three years in General Population followed by two years and five months progressing through either program. 97.  The Department of Justice’s letter of 26 September 2011 also stressed that, while generally inmates who were subject to special administrative measures were housed in the Special Security Unit, it was possible for such inmates to be housed at other prisons. Furthermore, if special administrative measure were vacated for an inmate at ADX, he could be transferred from ADX to other prison. This had occurred for seven of the thirteen inmates whose special administrative measures had been vacated. 98.  The applicants submitted general evidence as to the effect of solitary confinement on prisoners and specific evidence as to the prison regime at ADX Florence. 99.  The applicants also provided a report by a psychiatrist, Dr Terry Kupers, which had been prepared specifically for the present proceedings. He considered that a supermax prison regime did not amount to sensory deprivation but there was an almost total lack of meaningful human communication. This tended to induce a range of psychological symptoms ranging from panic to psychosis and emotional breakdown. All studies into the effects of supermax detention had found such symptoms after sixty days’ detention. Once such symptoms presented, it was not sufficient to return someone to normal prison conditions in order to remedy them. If supermax detention were imposed for an indeterminate period it also led to chronic despair. Approximately half of suicides in United States prisons involved the 6‑8% of prisoners held in such conditions. The effects of supermax conditions were worse for someone with pre-existing mental health problems. There was also evidence of solitary confinement leading to a range of physical illnesses. Dr Kuper’s conclusions were supported by a number of journal articles by psychologists and criminologists, which the applicants provided.[1] 100.  The specific evidence on ADX Florence included a series of statements by Professor Laura Rovner, Director of the Civil Rights Clinic at the University of Denver, which had acted for a number of prisoners at ADX Florence. Professor Rovner’s statements were based on her experience of ADX, the evidence of her clients, and various affidavits which had been prepared for litigation in the federal courts regarding ADX Florence. Her latest statement, of 27 May 2011, responded to the six declarations submitted by the Government. Her statement, and the other evidence provided by the applicants, may be summarised as follows. 101.  Professor Rovner recalled that one of the former wardens of ADX had publicly described the prison as “a clean version of hell”. Professor Rovner stated that, despite the evidence set out in the six declarations, conditions at ADX Florence had not changed significantly in the last two years. Solitary confinement for long periods continued. One lawyer, Mr Mark H. Donatelli, had conducted a survey which had found that at least forty-three inmates of ADX Florence had spent eight years or more in “lock-down” conditions there and at previous prisons.
Contact with staff could be as little as one minute per day. Some prisoners were placed on “single recreation status”, meaning no one else was permitted to be in adjoining recreation cells at the same time. Recreation privileges could be terminated for minor infractions: one prisoner was denied outdoor exercise for sixty days for trying to feed crumbs to birds. When he challenged this sanction through the grievance process, it was increased to ninety days. Upon further appeal he was told that the decision was not punitive but a managerial strategy to impress upon him the importance of adhering to institutional procedures. Indoor recreations were little more than cages with a single pull-up bar for exercise. There was nothing to do in outdoor recreation cages save to pace up and down. There was limited visibility – all that could be seen was the sky through chain linking. Recreation was frequently cancelled owing to staff shortages.
The evidence also showed that, despite the consensus in the medical profession that prisoners with mental illnesses should not be held in solitary confinement, ADX continued to house seriously mentally ill prisoners, including those with severe schizophrenia and bipolar disorder. Several inmates were too sick to communicate properly with their representatives; a report had been received of one prisoner who was too ill to write, but was living a cell that he had covered in six inches of rubbish and faeces. Several prisoners had stated in witness statements prepared for litigation in the United States courts, that there were mentally ill prisoners at ADX Florence who, because of their conditions, screamed all night, making sleep difficult for others. General medical facilities were also inadequate: there were only two doctors for 3,200 inmates at FCC Florence, and only basic healthcare needs were met. There were also reports from Human Rights Watch which indicated that force feeding of hunger strikers took place in an unnecessarily punitive and painful way.
Religious services were extremely limited – one Muslim inmate had only seen an imam three times – and one inmate in a general population unit had received an incident report for intoning the Azan. Books and educational activities were also limited.
For inmates, particularly those subjected to special administrative measures, telephone calls, and social visits were highly restricted and subject to monitoring. Contact with other inmates was generally prohibited and, when they were not, communication between cells could only be carried out by yelling, which was prohibited. Visits were limited to one adult visitor at a time, with no physical contact, and required fourteen days’ written notice. Evidence in cases brought by inmates who had been subjected to special administrative measures indicated that letters could be limited to three sheets of paper per week and certain family members could be refused clearance to write to or speak with an inmate. Special administrative measures could also mean that an inmate was prohibited from watching news channels on television, from receiving recent newspapers or any Arabic publications whatsoever; one inmate received his newspaper with whole sections removed. International telephone calls were expensive and liable to disruption.
Despite the adoption of objective criteria for placement at ADX, it remained the case that all those subjected to special administrative measures or convicted of terrorism offences were liable for placement, regardless of their security risk or their disciplinary record in other institutions. The placement hearing was window dressing: one hearing officer had carried out one hundred hearings and never found an inmate to be unsuitable for placement. There was evidence of hearings taking place post facto, in some cases many years after the transfer to ADX had been carried out. Inmates also received only twenty-four hours’ notice of a hearing and did not have the right to legal representation. There was evidence that hearing officers did not read all of the evidence submitted and based their decisions on unreliable evidence. Inmates did not see all the evidence against them. Professor Rovner also provided declarations by Arab Muslim clients, in which they stated that they had never been told the reasons for their placement at ADX and had been sent there after 9 September 2011, despite years of good conduct in other, much less restrictive prisons, both in the United States and elsewhere.
Although there had been an increase in the number of admissions to the step down program, the fact remained that many inmates were spending significant periods of time in solitary confinement prior to admission, despite having met the criteria for admission for years. Four clients of the Clinic had only been admitted to the program after periods of between seven and thirteen years in solitary confinement and only then after commencing litigation against the Bureau of Prisons. Another two clients had never been admitted, despite their clean disciplinary records and despite periods of eight to nine years at ADX. Even after the changes to procedures governing entry to the program, an inmate’s original crime continued to serve as the basis for placement at ADX; thus it was possible for an inmate to be unable to sufficiently mitigate the original reason for placement and so gain admission to the program. Moreover, if an inmate had never been told the reasons for his placement, he could not know what he had to do to gain admission to the program. The program required three years to complete and a prisoner needed one year of clear conduct in general population before being eligible for step down. Even eligibility for the program did not mean that a prisoner would be allowed into it.
Conditions in the first phase of the step down program did not differ significantly from general population units. According to one inmate, Mr Rezaq, lockdowns occurred frequently in J Unit, which meant inmates were confined to their cells, and could last days or even weeks. Inmates could also be removed from the program at any time without explanation or due process, even for the most minor infractions. Some had been removed from the program without receiving an incident report or were removed after receiving a report for an incident for which they were soon found not guilty. Yet, following such removals, they were either denied re-admission to the program or forced to spend years going through it again. The Bureau itself had estimated that only 5% of inmates progressed though the program in the minimum three years. Even successful completion of the step down program might only result in a transfer to a “communications management unit”, such as those housed at USP Terre Haute or USP Marion, where conditions remained restrictive.
According to Professor Rovner, it was difficult to dispute the evidence provided by the Government on special administrative measures (owing to restrictions contained in the measures themselves) but, on the basis of public information, she was able to state that the effect of the measures could amount to solitary confinement, even if an inmate was not detained at ADX. The indefinite prolongation of special administrative measures meant that certain Arab-Muslim inmates had spent between five and thirteen years in solitary confinement both before and after trial. Challenging such measures was impossible for inmates without access to legal representation. Legal aid was not available and, even if pro bono legal representation was obtained, the Department of Justice could still refuse to give the lawyers the necessary clearance; this had happened to her Clinic. 102.  The applicants also relied on two letters from Human Rights Watch. The first, dated 2 May 2007 to the Director of the Federal Bureau of Prisons, followed a tour the organisation had been given of ADX Florence. The letter expressed concerns that a number of prisoners convicted of terrorism offences had been sent to the prison based on the nature of their crimes and, despite good conduct since their arrival, had remained in general population units and thus outside the step-down programme for up to nine years. The letter made suggestions for improvement in respect of recreation, mail, telephone use, the library. It also noted that progress was to be made on better meeting prisoners’ religious needs, such as the provision of a full-time imam and commended the educational programmes available through the prison’s television system. In the letter Human Rights Watch expressed serious concerns as to prisoners’ inability to do any meaningful exercise in the indoor and outdoor recreation areas, owing to the size of these areas and the lack of any proper equipment. The letter urged the prison authorities to investigate reports of retaliation against prisoners who were on hunger strike in the form of transfer to harsher cells. The letter also said that Human Rights Watch was extremely concerned about the effects of long-term isolation and highly limited exercise on the mental health of prisoners and criticised reports of rushed consultations between prisoners and psychologists, as well as the fact that evaluations were carried out via closed circuit television. 103.  The applicants obtained a second letter from Human Rights Watch, dated 21 August 2008, which stated that Human Rights Watch considered conditions at ADX violated the United States’ treaty obligations under the International Covenant on Civil and Political Rights and the United Nations Convention against Torture. It was unremarkable that “minor adjustments” had been made to the regime but it remained in essence one of “long-term and indefinite incarceration in conditions of extreme social isolation and sensory deprivation”. 104.  The Eighth Amendment to the Constitution provides, inter alia, that cruel and unusual punishments shall not be inflicted. 105.  The Eighth Amendment requires prison officials to provide humane conditions of confinement, to ensure inmates receive adequate food, clothing shelter and medical care, and to take reasonable measures to guarantee their safety (Farmer v. Brennan 511 US 825 (1994). Only those deprivations denying the minimal civilized measure of life’s necessities are sufficiently grave to form the basis of an Eighth Amendment violation (Wilson v. Seiter 501 U.S. 294, 304 (1991); Rhodes v. Chapman 452 U.S. 337, 347 (1981)). A serious deprivation is necessary, because routine discomfort is part of the penalty inmates pay for their crimes (Hudson v. McMillan 503 US 1 (1992); Sandin v. Conner 515 US 472 (1995)). Thus, in order to establish that a deprivation violates the Eighth Amendment, a prisoner must satisfy: (i) an objective test by demonstrating a sufficiently serious deprivation; and (ii) a subjective test by showing that the conditions of confinement involve the deliberate imposition of pain or deliberate indifference to it (Wilson, cited above). 106.  In Hutto v. Finney 437 US 678 (1978), the Supreme Court upheld a lower court order limiting periods of punitive isolated confinement to thirty days, in circumstances where the lower court had found that conditions in the prison in question amounted to cruel and unusual punishment. The court recognised that confinement in an isolation cell was a form of punishment which was subject to scrutiny under Eighth Amendment standards but rejected the submission that indeterminate sentences to punitive isolation always constituted cruel and unusual punishment. 107.  Lower federal courts have found that whether an extended term of solitary confinement violates the Eighth Amendment will depend on the particular facts of each situation, including the circumstances, nature and duration of the confinement (DeSpain v. Uphoff 264 F.3d 965 (10th Cir. 2001)). Although they have recognised that prolonged conditions of solitary confinement may cause significant psychological damage (Davenport v. DeRobertis 844 F.2d 1310, 1313 (7th Cir. 1988)), the lower courts have, for the most part, rejected Eighth Amendment claims arising either from conditions of solitary confinement or from periods of confinement to cells for twenty-two or twenty-three hours per day (see, inter alia, Five Percenters 174 F.3d 471 (4th Cir. 1999); In re Long Term Admin. Segregation 174 F.3d 464 (4th Cir. 1999); Anderson v. County of Kern 45 F.3d 1310 (9th Cir. 1995); Peterkin v. Jeffes 855 F.2d. 1021 (3d cir. 1988); Smith v. Romer 107 F.3d 21 (10th Cir. 1997)). However, in Ruiz v. Johnson 37 F. Supp 2d 855 (1999), the highest level of administrative segregation in the Texan prison system was found to reach levels of psychological deprivation that violated the Eighth Amendment. There, the court found there had been deliberate indifference to a systemic pattern of extreme social isolation and reduced environmental stimulation. The objective test was found to have been met in respect of three prisoners who had been in solitary confinement for between twenty-nine and thirty-five years: Wilkerson v. Stalder 639 F. Supp. 2d 654 M.D.La., 2007. 108.  Lower courts outside the Tenth Circuit (which has jurisdiction over ADX Florence) have ruled that solitary confinement of prisoners with pre-existing serious mental illness can be sufficiently harmful to violate the objective test laid down in Wilson, cited above: see Jones ‘El v. Berge 164 F. Supp. 2d 1096 (2001) (concerning Wisconsin’s “supermax” prison) and Madrid v. Gomez 889 F. Supp 1146 (1995) (concerning detention at Pelican Bay State Prison, California). However, the subjective test laid down in Wilson may not be satisfied unless a plaintiff can show that prison officials attributed any deterioration in his mental state to the conditions of his confinement. Negligence in this respect does not suffice; deliberate indifference is required (Scarver v. Litscher 434 F. 3d 972 (7th Cir. 2006)). 109.  The Fifth Amendment protects against deprivation of life, liberty or property without due process of law. In the context of prison discipline, due process rights are triggered by an atypical and significant hardship on the inmate in relation to the ordinary incidents of prison life (Sandin v. Conner, cited above). This will include transfer to a “supermax” security prison (Wilkinson v. Austin 545 US 209 (2005)). In Wilkinson, the court upheld a system which gave notice of the reasons for placement in the supermax prison, an opportunity to reply and multiple levels of review. Periodic review of administrative segregation is also required to ensure that it is not used as a pretext for indefinite confinement (Hewitt v. Helms 459 US 460 (1983)).
Sandin has been interpreted by the Tenth Circuit as requiring prisoners to show that their conditions of confinement deviate substantially from the baseline accepted treatment of prisoners (Estate of DiMarco v. Wyoming Department of Corrections 473 F. 3d 1334 (10th Cir. 2007)). This test was found not to be satisfied by fourteen months’ solitary confinement in DiMarco because the prisoner in question had been provided with the ordinary essentials of prison life. 110.  In Sattar v. Gonzales 2009 WL 606115 (D.Colo.2009) the United States District Court for the District of Colorado dismissed a challenge to conditions of detention at ADX Florence and to the imposition of special administrative measures. The plaintiff had limited contact with his family and attorneys and so the court found that the “severe limitations of ADX confinement” did not amount to the necessary deprivation required by the objective test.
A constitutional challenge to the imposition of special administrative measures at ADX was also dismissed by the District Court in Al-Owhali v. Holder 1011 WL 288523 (D. Colo. 2011); the case is now the subject of an appeal.
In Georgacarakos v. Wiley, 2010 WL 1291833 (D.Colo. 2010) the District Court found that detention at ADX for five years did not amount to atypical and significant hardship, given the availability of social visits and phone calls, the opportunity to converse with other inmates in the recreation areas, and the possibility of transfer out of ADX via the step down program. Georgacarakos was recently followed in Matthews v. Wiley 744 F. Supp. 2d 1159 (D. Colo. 2010).
In Magluta v. United States Federal Bureau of Prisons, 29 May 2009, the District Court held that the plaintiff’s allegation that detention at ADX had led to a significant deterioration of his mental condition failed to satisfy the objective test in Wilson cited above. The plaintiff had not shown that conditions at ADX, even if lonely or uncomfortable, failed to provide basic human necessities; ADX was a prison and confinement was “intended to punish inmates, not coddle them”. 111.  In Hill v. Pugh 75 Fed. Appx. 715 (10th Cir. (2003)) United States Court of Appeals for the Tenth Circuit rejected an Eighth Amendment claim that ADX conditions were cruel and unusual. The plaintiff was isolated in his cell twenty-three hours a day for five days a week and twenty-four hours the remaining two days. However, his minimal physical requirements of food, shelter, clothing and warmth had been met and so the conditions showed neither an “unquestioned and serious deprivation of basic human needs” nor “intolerable or shocking conditions”. Similar conclusions were reached in Jordan v. the Federal Bureau of Prisons 191 Fed. Appx 639 (10th Cir. 2006), Ajaj v. United States 293 Fed.Appx. 575 (10th Cir. 2008). 112.  In Rezaq, et al. v. Nalley, et al, the plaintiffs brought Eighth Amendment claims concerning their placements at ADX at various dates between 1997 and 2003. The District Court granted the Bureau of Prisons’ motions for summary judgment: 2010 WL 5157317 (D. Colo. 2010); 2010 WL 5464294 (D. Colo. 2010). The court, following the recommendations of the Magistrate Judge, found that the plaintiff’s terrorist backgrounds and convictions provided a legitimate penological interest for transferring them to ADX, particularly when only thirty-five of the two hundred and six inmates in federal prisons with international terrorism convictions had been assigned to ADX. The plaintiffs’ conditions of confinement there were not so extreme as to be atypical and significant. The conditions were also different from those in Wilkinson v. Austin (see paragraph 109 above) in that ADX offered more opportunities for outdoor exercise, interaction with other inmates and educational programmes. There was also insufficient evidence of significant mental harm: there was no evidence that one of the plaintiff’s depression could be attributed to ADX; the remainder of the plaintiffs’ emotional problems were typically experienced by prisoners. Finally, owing to the availability of periodical reviews and the step down program, confinement at ADX was not indeterminate. The plaintiffs have appealed to the Court of Appeals for the Tenth Circuit, though they have all been transferred out of ADX. 113.  In Silverstein v. Federal Bureau of Prisons 704 F Supp. 2d 1077 (2010), before the District Court the plaintiff alleges that he has been held in solitary confinement at ADX Florence and other institutions since 1983. The Bureau of Prisons has sought summary judgment in its favour in respect of the plaintiff’s claims. A decision is awaited; a six-day jury trial was set to begin on 23 January 2012. 114.  The Council of Europe Guidelines on human rights and the fight against terrorism contain the following provision:
“XI.  Detention 1.  A person deprived of his/her liberty for terrorist activities must in all circumstances be treated with due respect for human dignity. 2.  The imperatives of the fight against terrorism may nevertheless require that a person deprived of his/her liberty for terrorist activities be submitted to more severe restrictions than those applied to other prisoners, in particular with regard to:
(i)  the regulations concerning communications and surveillance of correspondence, including that between counsel and his/her client;
(ii)  placing persons deprived of their liberty for terrorist activities in specially secured quarters;
(iii)  the separation of such persons within a prison or among different prisons, on condition that the measure taken is proportionate to the aim to be achieved.” 115.  The European Prison Rules (contained in Recommendation Rec(2006)2 of the Committee of Ministers of the Council of Europe to Member States) where relevant, provide as follows:
Security
 “51.1  The security measures applied to individual prisoners shall be the minimum necessary to achieve their secure custody. 51.2  The security which is provided by physical barriers and other technical means shall be complemented by the dynamic security provided by an alert staff who know the prisoners who are under their control. 51.3  As soon as possible after admission, prisoners shall be assessed to determine:
a.  the risk that they would present to the community if they were to escape;
b.  the risk that they will try to escape either on their own or with external assistance. 51.5  The level of security necessary shall be reviewed at regular intervals throughout a person’s imprisonment.”
Safety 52.1  As soon as possible after admission, prisoners shall be assessed to determine whether they pose a safety risk to other prisoners, prison staff or other persons working in or visiting prison or whether they are likely to harm themselves. 52.2  Procedures shall be in place to ensure the safety of prisoners, prison staff and all visitors and to reduce to a minimum the risk of violence and other events that might threaten safety. 52.3  Every possible effort shall be made to allow all prisoners to take a full part in daily activities in safety. 52.5  National health and safety laws shall be observed in prisons.
Special high security or safety measures 53.2  There shall be clear procedures to be followed when such measures are to be applied to any prisoner. 53.3  The nature of any such measures, their duration and the grounds on which they may be applied shall be determined by national law. 53.4  The application of the measures in each case shall be approved by the competent authority for a specified period of time. 53.5  Any decision to extend the approved period of time shall be subject to a new approval by the competent authority. 53.7  Any prisoner subjected to such measures shall have a right of complaint in the terms set out in Rule 70.
Requests and complaints 70.1  Prisoners, individually or as a group, shall have ample opportunity to make requests or complaints to the director of the prison or to any other competent authority. 70.3  If a request is denied or a complaint is rejected, reasons shall be provided to the prisoner and the prisoner shall have the right to appeal to an independent authority.” 116.  The 21st General Report of the European Committee for the Prevention of Torture, 10 November 2011, addressed solitary confinement, which it defined as whenever a prisoner is ordered to be held separately from other prisoners or was held together with one or two other prisoners. The Committee observed:
 “[Solitary confinement] can have an extremely damaging effect on the mental, somatic and social health of those concerned. This damaging effect can be immediate and increases the longer the measure lasts and the more indeterminate it is. The most significant indicator of the damage which solitary confinement can inflict is the considerably higher rate of suicide among prisoners subjected to it than that among the general prison population.”
The report therefore urged States to minimise the use of solitary confinement. It should be proportionate and, the longer it was used, the stronger the reasons for it had to be. It should be lawful and subject to accountability, with the fullest possible reasons given and records kept. It should be necessary and non-discriminatory. It should never be imposed as part of a sentence and, if imposed as a disciplinary sanction, the maximum period should be fourteen days. In that period, a prisoner should have at least one hour’s outdoor exercise per day and other appropriate mental stimulation.
The report also stated that the Committee’s recommended procedural safeguards should be rigorously followed where administrative solitary confinement was used for preventative purposes, including periodical and external reviews which considered, among other things, whether some of the restrictions imposed were strictly necessary. In such situations, prisoners should have an individual regime plan which attempted to maximise contact with others. Resources should also be made available to attempt to reintegrate the prisoner into the main prison community.
For material conditions in solitary confinement, the Committee stated that the cells used should meet the same minimum standards as those applicable to other prisoner accommodation. These included a cell of no less than six square metres, proper cell furnishings, adequate natural and artificial light, heating and ventilation, and sufficiently large exercise areas to allow genuine exertion.
The Committee also stated that medical personnel should never participate in decisions on solitary confinement and should report to the prison director whenever a prisoner’s health was put seriously at risk by solitary confinement. 117.  The Inter-American Commission on Human Rights has found that isolation could in itself constitute inhuman treatment, and a more serious violation could result for someone with a mental disability (Victor Rosario Congo v. Ecuador, case 11.427, 13 April 1999).
In Montero Aranguren et al (Detention Center of Catia) v. Venezuela, judgment of 5 July 2006, the Inter-American Court of Human Rights stated:
“...solitary confinement cells must be used as disciplinary measures or for the protection of persons only during the time necessary and in strict compliance with the criteria of reasonability, necessity and legality. Such places must fulfil the minimum standards for proper accommodation, sufficient space and adequate ventilation, and they can only be used if a physician certifies that the prisoner is fit to sustain it. (footnotes omitted)” 118.  Isolation for twenty-three hours a day in a two by two metres cell with ten minutes of sunlight per day was found by the United Nations Human Rights Committee to violate Article 7 of the ICCPR in Polay Campos v. Peru, CCPR/C/61/D/577/1994, 6 November 1997. 119.  In its recommendations to State parties, the United Nations Committee against Torture has recommended that:
- solitary confinement be strictly and specifically regulated by law and applied only in severe circumstances, with a view to its abolition (Conclusions and Recommendations in respect of Luxembourg, CAT/C/CR/28/2, at paragraph 6(b));
- there should be adequate review mechanisms relating to the determination and duration of solitary confinement (Conclusions and Recommendations in respect of Denmark, CAT/C/CR/28/1 at paragraph 7(d));
- solitary confinement for long periods of time may constitute inhuman treatment (Conclusions and Recommendations in respect of Switzerland, A/49/44, paragraph 133). 120.  The United Nations Special Rapporteur for Torture has found that isolation for twenty-two to twenty-four hours per day may amount to ill-treatment and, in certain instances, torture (Interim Report of 28 July 2008, A/63/175, at paragraphs 77-85). The report included a copy of the Istanbul statement on the use and effects of solitary confinement, which was adopted at the International Psychological Trauma Symposium in December 2007. The statement included the following on the effects of solitary confinement:
“It has been convincingly documented on numerous occasions that solitary confinement may cause serious psychological and sometimes physiological ill effects. Research suggests that between one third and as many as 90 per cent of prisoners experience adverse symptoms in solitary confinement. A long list of symptoms ranging from insomnia and confusion to hallucinations and psychosis has been documented. Negative health effects can occur after only a few days in solitary confinement, and the health risks rise with each additional day spent in such conditions.
Individuals may react to solitary confinement differently. Still, a significant number of individuals will experience serious health problems regardless of the specific conditions, regardless of time and place, and regardless of pre-existing personal factors. The central harmful feature of solitary confinement is that it reduces meaningful social contact to a level of social and psychological stimulus that many will experience as insufficient to sustain health and well being.” 121.  In his Interim Report of 5 August 2011, A/66/268, the current Special Rapporteur for Torture found that where the physical conditions and the prison regime of solitary confinement caused severe mental and physical pain or suffering, when used as a punishment, during pre-trial detention, indefinitely prolonged, on juveniles or persons with mental disabilities, it could amount to cruel, inhuman or degrading treatment or punishment and even torture. The report highlighted a number of general principles to help to guide States to re-evaluate and minimise its use and, in certain cases, abolish the practice of solitary confinement. He stated that the practice should be used only in very exceptional circumstances, as a last resort, for as short a time as possible. He further emphasised the need for minimum procedural safeguards, internal and external, to ensure that all persons deprived of their liberty were treated with humanity and respect for the inherent dignity of the human person.
