Abstract: This article examines the principle of uti possidetis that originates from the Roman civil law and has transformed into the general principle of international law under the influence of practice of the states, international judicial bodies, and specialized international arbitration courts. The author reviews the fundamental role of the principle pertaining to the case of disintegration of the Socialist Federative Republic of Yugoslavia (SFRY): acknowledgement and retaining of domestic borders – former territorial units of the erstwhile state, and their transformation into the international boundaries of the newly formed sovereign nations. Special attention is given to the work of Badinter Commission established by the European Union for settling various legal issues within the framework of disintegration of the Socialist Yugoslavian State, including the boundary and territorial disputes and conflicts in the process.
