"A State is immune from the jurisdiction of the courts of the United Kingdom except as provided in the provisions of Part 1 of the Act."
"A court shall give effect to the immunity conferred even though the State does not appear in the proceedings in question."

"(b) the "members of the mission" are the head of the mission and the members of the staff of the mission; (c) the "members of the staff of the mission" are the members of the diplomatic staff, of the administrative and technical staff and of the service staff of the mission;... (f) the "members of the administrative and technical staff" are the members of the staff of the mission employed in the administrative and technical service of the mission; (g) the "members of the service staff" are the members of the staff of the mission in the domestic service of the mission"
"But we do not consider that there can be jurisdiction over claims by those engaged in carrying out the work of the mission in however humble a role. The factors which have led us to reach our conclusion on the general principle [and he refers back to page 228 of the decision] apply to all such employees. They are engaged in carrying out the public functions of the foreign state: an investigation of their claim might well require an investigation by the tribunal into the conduct of the diplomatic mission. Therefore, in our judgment, at common law a state is immune from claims for unfair dismissal brought by employees at a diplomatic mission who are engaged in carrying on the work of that mission."
