Outline of Final Research Achievements

In this study, I explored the functions that the so-called "intervention by invitation" has within the United Nations system. As a result of this study, following points emerged.First, interventions by foreign armed forces of a states in a civil war of another was traditionally justified by the self-preservation or self-defense of the former and accordingly any invitation by the established government of the latter state was not considered a condition sine qua non for the intervention. An invitation by the established government as a necessary condition for the intervention in a civil war was introduced as a consequence of the UN Charter prohibition on the use of force.
Second, in the post Cold War era, intervention by invitation has begun to play more positive function in the UN System. In particular it has been considered as complementary to the UN collective security system.
