Právo národů na sebeurčení jako faktor mezinárodních vztahů

This paper explores the current understanding of the right of peoples to self-determination and its impact on international relations. A number of new states have gained international recognition outside the scope of decolonisation, several of which have not fulfilled the usual criteria for statehood, based on existing state practice. In addition, the parent states of Bangladesh, Croatia, Bosnia and Herzegovina as well as Kosovo have not consented to the secession of these territories. The main purpose of this paper is to determine whether based on the stipulations of international documents and mainly on existing state practice, it is possible to verify the existence of a customary law enabling peoples to unilaterally secede. Such a right would pose a threat to the future application of the principle of territorial integrity as one of the basic principles of international relations. In order to answer this question I compare case studies of successful and unsuccessful nations striving for their own state outside the realm of decolonisation. Based on this comparison I analyse the current understanding of the right to self-determination and its impact on international relations. I conclude by stating that it is not possible to unambiguously confirm the existence of such a right. However, in practice the principle of territorial integrity is being breached nonetheless, due to persisting uncertainties regarding the possible application of secession by peoples whose internal right to self-determination was not respected. Together with the fact that the current concept of self-determination ignores collective rights of national groups, this poses a threat to international stability.
