“2 Application of Vienna Convention. (1) Subject to section 3 of this Act, the Articles set out in Schedule 1 to this Act (being Articles of the Vienna Convention on Diplomatic Relations signed in 1961) shall have the force of law in the United Kingdom and shall for that purpose be construed in accordance with the following provisions of this section.”
“A diplomatic agent shall enjoy immunity from the criminal jurisdiction of the receiving State. He shall also enjoy immunity from its civil and administrative jurisdiction, except in the case of: (a) a real action relating to private immovable property situated in the territory of the receiving State, unless he holds it on behalf of the sending State for the purposes of the mission; (b) an action relating to succession in which the diplomatic agent is involved as executor, administrator, heir or legatee as a private person and not on behalf of the sending State; (c) an action relating to any professional or commercial activity exercised by the diplomatic agent in the receiving State outside his official functions”
“The functions of a diplomatic mission consist, inter alia, in: (a) representing the sending State in the receiving State; (b) protecting in the receiving State the interests of the sending State and of its nationals, within the limits permitted by international law; (c) negotiating with the Government of the receiving State; (d) ascertaining by all lawful means conditions and developments in the receiving State and reporting thereon to the Government of the sending State; (e) promoting friendly relations between the sending State and the receiving State, and developing their economic, cultural and scientific relations.”
“…. reflects the fact that acts so performed are in law the acts of the sending State. Denza “Diplomatic Law”, third edition, explains the position as follows (at 439): ‘The acts of a diplomatic agent in the exercise of his official functions are in law the acts of the sending State. It has therefore always been the case that the diplomat cannot at any time be sued in Britain in respect of such acts since this would be indirectly to implead a sending State.’ ”
“…the legal basis of immunity from jurisdiction of a State is different from the immunity of diplomatic agents. Immunity of foreign representatives is meant to protect their freedom in exercising their functions – “ne impediat legatio” (Stefko-Ehrlich), whereas the basis of the immunity from jurisdiction of foreign states is the democratic principle of their equality, irrespective of their size and power, which, in consequence, excludes jurisdiction of one State over another (“Par in parem non habet judicium”), unless there has been voluntary submission to such jurisdiction either by a definite document or by a conclusive action (Ehrlich, Law of Nations, p.96). …in examining questions concerning immunity from jurisdiction of foreign States, one has to base oneself directly on general principles universally adopted in international relations. The most essential of these principles is the principle of reciprocity among States which results from the fundamental principle of their equality (this principle must govern diplomatic immunity as well, not withstanding its different aspect). The principle of reciprocity is based on recognition or non-recognition of the immunity from jurisdiction by one State of another in the same measure as the latter recognises or refuses to recognise immunity from jurisdiction of other States.”
“The Article governs the personal immunity of diplomats. The extent of this immunity differs from that of State immunity; generally, it extends further. In principle, therefore, the extent of State immunity cannot be determined from that of diplomatic immunity”
“I therefore believe the employment of the Claimants and the way they were treated during the employment was outside the first respondent’s job functions…”
“The claims do not concern an employee of the State itself or even one who is involved in the diplomat’s work. They do not even concern a cleaner at the embassy. They involve low grade domestic workers in the respondents’ private residence. There is no obvious need to investigate or touch on the diplomatic or organisational policy of the State or its diplomats in any way in order to resolve the claims. Nor are these cases of recruitment of staff. It concerns the treatment of staff who have been taken on”
“It is not the tribunal’s ultimate role to investigate and make a finding as to whether trafficking has taken place and, although there may be some factual overlap, many different facts and legal issues would be involved in resolving the particular employment claims made. The connection with the claims involved here and the scope of art 4 appears to me to be too remote.”
