HASSAN v. THE UNITED KINGDOM – JUDGMENT 53 16070/90, 16071/90, 16072/90 and 16073/90, § 185, ECHR 2009), and it considers that these observations apply equally in relation to Article 5. Moreover, the International Court of Justice has held that the protection offered by human rights conventions and that offered by international humanitarian law co-exist in situations of armed conflict (see paragraphs 35-37 above). In its judgment Armed Activities on the Territory of the Congo, the International Court of Justice observed, with reference to its advisory opinion concerning The Legal Consequences of the Construction of a Wall in the Occupied Palestinian Territory, that “[a]s regards the relationship between international humanitarian law and human rights law, there are thus three possible situations: some rights may be exclusively matters of international humanitarian law; others may be exclusively matters of human rights law; yet others may be matters of both these branches of international law” (see paragraphs 36 and 37 above). The Court must endeavour to interpret and apply the Convention in a manner which is consistent with the framework under international law delineated by the International Court of Justice. 103. In the light of the above considerations, the Court accepts the Government’s argument that the lack of a formal derogation under Article 15 does not prevent the Court from taking account of the context and the provisions of international humanitarian law when interpreting and applying Article 5 in this case. 104. Nonetheless, and consistently with the case-law of the International Court of Justice, the Court considers that, even in situations of international armed conflict, the safeguards under the Convention continue to apply, albeit interpreted against the background of the provisions of international humanitarian law. By reason of the co-existence of the safeguards provided by international humanitarian law and by the Convention in time of armed conflict, the grounds of permitted deprivation of liberty set out in subparagraphs (a) to (f) of that provision should be accommodated, as far as possible, with the taking of prisoners of war and the detention of civilians who pose a risk to security under the Third and Fourth Geneva Conventions. The Court is mindful of the fact that internment in peacetime does not fall within the scheme of deprivation of liberty governed by Article 5 of the Convention without the exercise of the power of derogation under Article 15 (see paragraph 97 above). It can only be in cases of international armed conflict, where the taking of prisoners of war and the detention of civilians who pose a threat to security are accepted features of international humanitarian law, that Article 5 could be interpreted as permitting the exercise of such broad powers. 105. As with the grounds of permitted detention already set out in those subparagraphs, deprivation of liberty pursuant to powers under international humanitarian law must be “lawful” to preclude a violation of Article 5 § 1. This means that the detention must comply with the rules of international
