Indigenous people living within the territorial jurisdiction of a nation state face certain hazards in raising their voices for autonomy. A liberal State like India provides welfare oriented social services for the indigenous people either subsidised or as freebies to meet their development aspirations. Despite continuing for a long time, such measures fail to satisfy their aspiration for attaining autonomy. It is at this time, they come out with the demands for self rule. But they are bound by the rule of laws and Constitutional provisions within which they are expected to raise their demands for autonomy. The Constitution of India provides for limited autonomy for indigenous people to rule over their resources within the dominant territories in the form of a political system generated under the provisions of Sixth schedule. This set up is possible within the territory of a sub-national level which is controlled by an executive set-up more like a government regime and a legislative set-up more like a legislature. This framework is working effectively in case of three indigenous tribes namely Karbi, Dimasa (both hill tribes) and Bodo (plain tribe). But more and more tribes are now demanding autonomy within this framework. However, this is not an automatic mechanism to achieve by any tribe -the institutional set up of Sixth Schedule. The system of autonomy under sixth schedule is meant for this scheduled tribe only. Nevertheless, as the system involves both an institutional and territorial government, the creation of such a political system is subject to transfer of huge resources from government for running the show. This paper is an attempt to analyse the backdrop under which a Scheduled tribe namely Mising comes out of their traditional set up to demand for autonomy and the path and process it follows towards achieving this.
