50 HASSAN v. THE UNITED KINGDOM – JUDGMENT 2. The Court’s assessment (a) The general principles to be applied 96. Article 5 § 1 of the Convention sets out the general rule that “[e]veryone has the right to liberty and security of the person” and that “[n]o one shall be deprived of his liberty” except in one of the circumstances set out in sub-paragraphs (a) to (f). 97. It has long been established that the list of grounds of permissible detention in Article 5 § 1 does not include internment or preventive detention where there is no intention to bring criminal charges within a reasonable time (see Lawless v. Ireland (no. 3), 1 July 1961, §§ 13 and 14, Series A no. 3; Ireland v. the United Kingdom, 18 January 1978, § 196, Series A no. 25; Guzzardi v. Italy, 6 November 1980, § 102, Series A no. 39; Jėčius v. Lithuania, no. 34578/97, §§ 47-52, ECHR 2000-IX; and Al-Jedda, cited above, § 100). Moreover, the Court considers that there are important differences of context and purpose between arrests carried out during peacetime and the arrest of a combatant in the course of an armed conflict. It does not take the view that detention under the powers provided for in the Third and Fourth Geneva Conventions is congruent with any of the categories set out in subparagraphs (a) to (f). Although Article 5 § 1(c) might at first glance seem the most relevant provision, there does not need to be any correlation between security internment and suspicion of having committed an offence or risk of the commission of a criminal offence. As regards combatants detained as prisoners of war, since this category of person enjoys combatant privilege, allowing them to participate in hostilities without incurring criminal sanctions, it would not be appropriate for the Court to hold that this form of detention falls within the scope of Article 5 § 1(c). 98. In addition, Article 5 § 2 requires that every detainee should be informed promptly of the reasons for his arrest and Article 5 § 4 requires that every detainee should be entitled to take proceedings to have the lawfulness of his detention decided speedily by a court. Article 15 of the Convention provides that “[i]n time of war or other public emergency threatening the life of the nation”, a Contracting State may take measures derogating from certain of its obligations under the Convention, including Article 5. In the present case, the United Kingdom did not purport to derogate under Article 15 from any of its obligations under Article 5. 99. This is the first case in which a respondent State has requested the Court to disapply its obligations under Article 5 or in some other way to interpret them in the light of powers of detention available to it under international humanitarian law. In particular, in Al-Jedda, cited above, the United Kingdom Government did not contend that Article 5 was modified or displaced by the powers of detention provided for by the Third and Fourth Geneva Conventions. Instead they argued that the United Kingdom
