40 HASSAN v. THE UNITED KINGDOM – JUDGMENT which the States decided, when drafting the Convention, to apply to territories overseas for whose international relations they were responsible. Article 56 § 1 provides a mechanism whereby any State may decide to extend the application of the Convention, ‘with due regard ... to local requirements’, to all or any of the territories for whose international relations it is responsible. The existence of this mechanism, which was included in the Convention for historical reasons, cannot be interpreted in present conditions as limiting the scope of the term ‘jurisdiction’ in Article 1. The situations covered by the ‘effective control’ principle are clearly separate and distinct from circumstances where a Contracting State has not, through a declaration under Article 56, extended the Convention or any of its Protocols to an overseas territory for whose international relations it is responsible (see Loizidou (preliminary objections), cited above, §§ 86-89 and Quark Fishing Ltd v. the United Kingdom (dec.), no. 15305/06, ECHR 2006-...). (δ) The Convention legal space (‘espace juridique’) 141. The Convention is a constitutional instrument of European public order (see Loizidou v. Turkey (preliminary objections), cited above, § 75). It does not govern the actions of States not Parties to it, nor does it purport to be a means of requiring the Contracting States to impose Convention standards on other States (see Soering, cited above, § 86). 142. The Court has emphasised that, where the territory of one Convention State is occupied by the armed forces of another, the occupying State should in principle be held accountable under the Convention for breaches of human rights within the occupied territory, because to hold otherwise would be to deprive the population of that territory of the rights and freedoms hitherto enjoyed and would result in a ‘vacuum’ of protection within the ‘Convention legal space’ (see Loizidou (merits), cited above, §78; Banković, cited above, § 80). However, the importance of establishing the occupying State’s jurisdiction in such cases does not imply, a contrario, that jurisdiction under Article 1 of the Convention can never exist outside the territory covered by the Council of Europe Member States. The Court has not in its case-law applied any such restriction (see amongst other examples Öcalan, Issa, Al-Saadoon and Mufdhi, Medvedyev, all cited above).” 75. In Al-Skeini, cited above, the Court found that the applicants’ relatives fell within United Kingdom jurisdiction because during the period 1 May 2003-28 June 2004 the United Kingdom had assumed authority for the maintenance of security in South East Iraq and the relatives were killed in the course of security operations carried out by United Kingdom troops pursuant to that assumption of authority (Al-Skeini §§ 143-150). In the light of this finding, it was unnecessary to determine whether jurisdiction also arose on the ground that the United Kingdom was in effective military control of South East Iraq during that period. However, the statement of facts in Al-Skeini included material which tended to demonstrate that the United Kingdom was far from being in effective control of the south-eastern area which it occupied, and this was also the finding of the Court of Appeal, which heard evidence on this question in the domestic Al-Skeini proceedings (see Al-Skeini, cited above, §§ 20-23 and § 80). The present case concerns an earlier period, before the United Kingdom and its coalition partners had declared that the active hostilities phase of the conflict had ended and that
