Abstract
This paper is aimed to analyse if the armed interventions of regional and sub-regional organizations in the territory of a Member State comply with international law from an overall point of view. The treaties of the regional and sub-regional organizations - which have performed armed interventions in the territory of a Member State until today – have been surveyed, in order to assess whether and how far they include such kind of armed interventions. The conducts more often performed by regional and sub-regional organizations on this matter have been then analysed, in order to appraise their compliance with international law. Lastly, the element of the consent from the Member State target of the armed intervention has been surveyed.
