A. AND OTHERS v. THE UNITED KINGDOM JUDGMENT 91 found, as well as any special circumstances pertaining to the context of the case. 251. The Court reiterates that in the McCann and Others judgment (cited above, § 219), it declined to make any award in respect of pecuniary or nonpecuniary damage arising from the violation of Article 2 of the Convention, having regard to the fact that the three terrorist suspects who were killed had been intending to plant a bomb in Gibraltar. It considers that the present case is distinguishable, since it has not been established that any of the applicants has engaged, or attempted to engage, in any act of terrorist violence. 252. The decision whether to award monetary compensation in this case and, if so, the amount of any such award, must take into account a number of factors. The applicants were detained for long periods, in breach of Article 5 § 1, and the Court has, in the past, awarded large sums in just satisfaction in respect of unlawful detention (see, for example, Assanidze v. Georgia [GC], no. 71503/01, ECHR 2004-II, or the cases cited by the applicants in paragraph 235 above). The present case is, however, very different. In the aftermath of the al-Qaeda attacks on the United States of America of 11 September 2001, in a situation which the domestic courts and this Court have accepted was a public emergency threatening the life of the nation, the Government were under an obligation to protect the population of the United Kingdom from terrorist violence. The detention scheme in Part 4 of the 2001 Act was devised in good faith, as an attempt to reconcile the need to prevent the commission of acts of terrorism with the obligation under Article 3 of the Convention not to remove or deport any person to a country where he could face a real risk of ill-treatment (see paragraph 166 above). Although the Court, like the House of Lords, has found that the derogating measures were disproportionate, the core part of that finding was that the legislation was discriminatory in targeting non-nationals only. Moreover, following the House of Lords’ judgment, the detention scheme under the 2001 Act was replaced by a system of control orders under the Prevention of Terrorism Act 2005. All the applicants in respect of whom the Court has found a violation of Article 5 § 1 became, immediately upon release in March 2005, the subject of control orders. It cannot therefore be assumed that, even if the violations in the present case had not occurred, the applicants would not have been subjected to some restriction on their liberty. 253. Against this background, the Court finds that the circumstances justify the making of an award substantially lower than that which it has had occasion to make in other cases of unlawful detention. It awards 3,900 euros (EUR) to the first, third and sixth applicants; EUR 3,400 to the fifth and ninth applicants; EUR 3,800 to the seventh applicant; EUR 2,800 to the eighth applicant; EUR 2,500 to the tenth applicant; and EUR 1,700 to the eleventh applicant, together with any tax that may be chargeable.
