In cases where people lack representation by a state's government, they also may be considered a separate people, but under current law cannot claim the right to self-determination. (Wikipedia)

Essentially, the right to self-determination is the right of a people to determine its own destiny. In particular, the principle allows a people to choose its own political status and to determine its own form of economic, cultural and social development. Exercise of this right can result in a variety of different outcomes ranging from political independence through to full integration within a state. (unpo.org)
