A. AND OTHERS v. THE UNITED KINGDOM JUDGMENT 29 an unspecified period without trial. While we recognise that the Special Advocate has a difficult task when he has and can obtain no instructions on closed material, he is able to test evidence from the Security Service and to draw our attention to material which assists the Appellant’s case.” SIAC found that there was ample evidence to support the view that the applicant was involved in fraudulent activities. The evidence before it, most of it closed, was sufficient to establish that he was doing it to raise money for terrorist causes and to support those involved in terrorism. It therefore dismissed the appeal against certification. 64. SIAC reached similar decisions in its review judgments of 4 August 2004 and 16 February 2005. In the latter judgment, it noted that although the applicant had been transferred to Broadmoor Secure Mental Hospital because of mental health problems, that made no difference to the assessment of the risk to national security which he would pose if released. 11. The eleventh applicant 65. The eleventh applicant is an Algerian national. He entered the United Kingdom in February 1998, using a false Italian identity card, and claimed asylum the following week. While his claim was pending, in July 2001, he travelled to Georgia using a false French passport and was deported back to the United Kingdom, where he was informed that his travel outside the United Kingdom had terminated his asylum claim. He made a second claim for asylum, which was refused on 21 August 2001. The applicant absconded. He was arrested on 10 October 2001 and held in an immigration detention centre, from which he absconded in February 2002. He was rearrested on 19 September 2002 and detained at Belmarsh Prison under immigration law provisions. 66. On 2 October 2003 the Secretary of State certified him as an international terrorist under section 21 of the 2001 Act and made a deportation order against him on grounds of national security. 67. In its judgment of 12 July 2004, dismissing the eleventh applicant’s appeal against certification, SIAC set out the open case against him. It was alleged that he was an established and senior member of the Abu Doha group (see paragraph 26 above). In July 2001 he had attempted to travel to Chechnya and, when arrested by the Georgian police, he had been found in possession of telephone numbers associated with a senior member of the Abu Doha group and a named member of GSPC, who was known to be involved in fund-raising for the Chechen Mujahaddin. He was alleged to have provided money and logistical support to a North African extremist Islamist network based in Pakistan and Afghanistan, with links to al-Qaeda, and to have assisted members of the Abu Doha group in travelling to Afghanistan, Pakistan and Chechnya. He had lived at the Finsbury Park Mosque for over a year in 1999/2000. He was very security-conscious and during a trip to St Albans in September 2001 he had taken measures to
