Outline of Final Research Achievements

The rules on State immunity ensure that States are able to properly perform their sovereign functions and maintain a stable inter-State relationship. The decision whether to grant immunity to a State has been based not on the classic application of jure imperii or jure gestionis criteria but on the consideration of different factors which vary according to the type of the case in question, in order to achieve the rationale of State immunity.
The rationale of immunity of State officials is the same as State immunity. In order to achieve this rationale, international law has recognized that Heads of State, Heads of Government and Ministers for Foreign Affairs (the “troika”) enjoy immunity ratione personae, while other State officials basically enjoy at least immunity ratione materiae. However, views remain especially divided on immunity ratione materiae from the exercise of foreign criminal jurisdiction in respect of crimes under international law.
