54 A. AND OTHERS v. THE UNITED KINGDOM JUDGMENT having to choose between conditions of detention which they found intolerable and the risk of whatever treatment they might have to suffer if they consented to deportation. Moreover, their previous experiences and pre-existing mental and physical problems made them particularly vulnerable to the ill effects of arbitrary detention. The discrimination they suffered, since only foreign nationals were subject to detention under the 2001 Act, compounded their anguish. 116. The high security conditions of detention, in Belmarsh Prison and Broadmoor Secure Mental Hospital, were inappropriate and damaging to their health. More fundamentally, however, the indeterminate nature of the detention, with no end in sight, and its actual long duration gave rise to abnormal suffering, in excess of that inherent in detention. This was compounded by other unusual aspects of the regime, such as the secret nature of the evidence against them. The fact that the indifference of the authorities to the applicants’ situation was sanctioned by parliamentary statute did not mitigate their suffering. 117. Taken cumulatively, these factors caused the applicants an intense degree of anguish. The medical evidence and reports of the CPT and group of consultant psychiatrists (see paragraphs 101 and 76 above) demonstrated that the detention regime also harmed or seriously risked harming all of them and, in the case of the first, fifth, seventh and tenth applicants, did so extensively. 118. The applicants claimed that SIAC’s power to grant bail did not effectively function during the period when they were detained: firstly, because the scope of the remedy was jurisdictionally unclear; secondly, because the procedure was subject to delay; thirdly, because the threshold for granting bail was too high. An applicant for bail was required to demonstrate an “overwhelming likelihood” that his continued detention would lead to a physical or mental deterioration, such as to constitute inhuman and degrading treatment contrary to Article 3 of the Convention. The jurisdiction was described as “exceptional”, requiring the “circumstances to be extreme”. Even then, the only available remedy was to substitute house arrest for detention (see paragraph 79 above). 2. The Government 119. The Government denied that the applicants’ rights under Article 3 had been infringed. They pointed out that SIAC and the Court of Appeal had rejected the applicants’ complaints under Article 3 and that the House of Lords had not found it necessary to determine them (see paragraphs 15, 16 and 22 above). 120. Detention without charge was not in itself contrary to Article 3 and in many instances it was permitted under Article 5 § 1. The detention was indeterminate but not indefinite. The legislation remained in force for only five years and was subject to annual renewal by both Houses of Parliament.
