“The conclusion which emerges is that in considering, under the ‘restrictive’ theory whether state immunity should be granted or not, the court must consider the whole context in which the claim against the state is made, with a view to deciding whether the relevant act(s) upon which the claim is based, should, in that context, be considered as fairly within an area of activity … of a private law character, in which the state has chosen to engage, or whether the relevant act(s) should be considered as having been done outside that area, and within the sphere of governmental or sovereign activity.” 54 In the great majority of cases arising from contract, including employment cases, the categorisation will depend on the nature of the relationship between the parties to which the contract gives rise. This will in turn depend on the functions which the employee is employed to perform. 55 The Vienna Convention on Diplomatic Relations divides the staff of a diplomatic mission into three broad categories: (i) diplomatic agents, i e the head of mission and the diplomatic staff; (ii) administrative and technical staff; and (iii) staff in the domestic service of the mission. Diplomatic agents participate in the functions of a diplomatic mission defined in article 3, principally representing the sending state, protecting the interests of the sending state and its nationals, negotiating with the government of the receiving state, ascertaining and reporting on developments in the receiving state and promoting friendly relations with the receiving state. These functions are inherently governmental. They are exercises of sovereign authority. Every aspect of the employment of a diplomatic agent is therefore likely to be an exercise of sovereign authority. The role of technical and administrative staff is by comparison essentially ancillary and supportive. It may well be that the employment of some of them might also be exercises of sovereign authority if their functions are sufficiently close to the governmental functions of the mission. Cypher clerks might arguably be an example. Certain confidential secretarial staff might be another: … … In Cudak v Lithuania 51 EHRR 15, Sabeh El Leil v France 54 EHRR 14, Wallishauser vAustria CE:ECHR:2012:0717JUD000015604 and Radunovic v Montenegro CE:ECHR:2016:1025JUD004519713, all cases concerning the administrative and technical staff of diplomatic missions, the test applied by the Strasbourg court was whether the functions for which the applicant was employed called for a personal involvement in the diplomatic or political operations of the mission, or only in such activities as might be carried on by private persons. In Mahamdia v People’s Democratic Republic of Algeria (Case C-154/11 )[2013] ICR 1 , paras 55—57 the Court of Justice of the European Union applied the same test, holding that the state is not immune “where the functions carried out by the employee do not fall within the exercise of public powers”
“has to be viewed together with the principle that each state possesses sovereignty over its own territory and that there flows from that sovereignty the jurisdiction of the state over events and persons within that territory. Exceptions to the immunity of the state represent a departure from the principle of sovereign equality. Immunity may represent a departure from the principle of territorial sovereignty and the jurisdiction which flows from it”
“Sengupta v Republic of India was decided at an early stage of the development of the law in this area and, in my opinion, the test applied by the Employment Appeal Tribunal was far too wide. I agree with the criticism of the decision in Fox, The Law of State Immunity, p 199n, that the reasoning had more regard to the purpose than to the juridical character of the claimant’s employment.” 67. Against that important background, I turn to the narrow question of whether I should disapply s 4(2)(a) SIA by reference to article 47 of the Charter. There is a tension, in this case, between two competing principles: (1) that immunity should apply between a state and nationals of that state; and (2) immunity should not apply in respect of locally recruited staff who are nationals of and permanently resident in the forum state. From the Vienna Convention, it would seem that the latter is the dominant consideration. 68. In this case, the Claimant, although in both categories, is in any event, on the material facts, much more in the second. It is almost, although not quite, a coincidence that the Claimant had Spanish nationality (though it was essential that she was bilingual). She was, effectively, a member of locally recruited staff who spoke Spanish and happened to have dual Spanish nationality. 69. I therefore hold that, for the same reasons of principle as s 4(2)(b) was disapplied in Benkharbouche, s 4(2)(a) should be disapplied in respect of the Claimant’s EqA claims in this case.” “Sengupta v Republic of India was decided at an early stage of the development of the law in this area and, in my opinion, the test applied by the Employment Appeal Tribunal was far too wide. I agree with the criticism of the decision in Fox, The Law of State Immunity, p 199n, that the reasoning had more regard to the purpose than to the juridical character of the claimant’s employment.”
