Self-determination has been defined as the right of people to freely determine their political status and pursue their economic, social, and cultural development. During decolonization, the right aimed towards the establishment of the self-government for the peoples – inhabitants of nonself-governed colonial territories. Over the last half century, the process of decolonization resulted in a successful attainment of formal sovereignty for the former colonies. However, the liberation movements reached self-determination externally but failed to reach it internally. Since the process of decolonization is formally over, there is a change in a right holder and the mode for practicing self-determination. Except for an aggregate population – people within the state that can practice an external form of self – determination, as a process internal self-determination can be granted to different subnational groups. The ones that reached external self-determination should accept legal norms that grant forms of internal self-determination.
