4 AUAD v. BULGARIA JUDGMENT place him in detention pending the carrying out of that measure. In support of the proposal he said that the applicant was a member of Usbat al-Ansar, which he described as a Sunni terrorist organisation acting in close cooperation with Hamas, Jund al-Sham, Ansar Allah and others (see paragraphs 54, 59-61 and 78 below). The applicant was alleged to have taken part in “wet jobs” for the organisation and in the assassinations of more than ten members of a Palestinian political party; he was being sought by the Lebanese authorities in connection with that. He was a relative of one of the leaders of Usbat al-Ansar. The available information showed that the applicant followed strictly the organisation’s ideas and would unhesitatingly follow the orders of its leaders. This had been confirmed by partner security services. It had also been established that the applicant kept contacts with two asylum seekers who were known to adhere to a terrorist organisation active in Ain al-Hilweh. One of them had been implicated in the killing of a member of a Palestinian political party and kept close contacts with Usbat al-Ansar and Fatah al-Islam (see paragraph 65, 72, 74, 78 and 81 below). All of that showed that the applicant by reason of his previous and current activities presented a serious threat to the national security of Bulgaria, and that his presence in the country discredited it as a reliable partner in the fight against international terrorism. 15. On 17 November 2009 the head of the State Agency for National Security made an order for the applicant’s expulsion. He also barred him from entering or residing in Bulgaria for ten years, “in view of the reasons set out in [the above-mentioned] proposal and the fact that his presence in the country represent[ed] a serious threat to national security”. The order relied on sections 42 and 44(1) of the Aliens Act 1998. No factual grounds were given, in accordance with section 46(3) of the Act (see paragraph 33 below). The order further provided that it was to be brought to the attention of the applicant and was immediately enforceable, as provided by section 44(4)(3) of the Act (see paragraph 34 below). 16. Concurrently with that order the head of the State Agency for National Security made an order for the applicant’s detention pending deportation (see paragraphs 42 and 43 below). He reasoned that the information featuring in the proposal showed that the applicant would try to prevent the enforcement of the expulsion order, and accordingly directed that the detention order should be immediately enforceable. He also instructed the immigration authorities urgently to take all necessary steps to enforce the expulsion order. 17. On 20 November 2009 the applicant was arrested and placed in a special detention facility pending enforcement of the expulsion order. He submits that when brought there he was informed about the two orders against him but was not given copies of them. 18. On 19 May 2011, in view of the impending expiry of the maximum permissible period of detention pending deportation – eighteen months (see
