The United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) is a comprehensive statement addressing the human rights of Indigenous peoples. It was drafted and formally debated for over 20 years prior to being adopted by the General Assembly on 13 September 2007. The document emphasizes the rights of Indigenous peoples to live in dignity, to maintain and strengthen their own institutions, cultures and traditions and to pursue their self-determined development, in keeping with their own needs and aspirations. UN Declarations are generally not legally binding; however, they represent the dynamic development of international legal norms and reflect the commitment of states to move in certain directions, abiding by certain principles. The Declaration, however, is widely viewed as not creating new rights. Rather, it provides a detailing or interpretation of the human rights enshrined in other international human rights instruments of universal resonance – as these apply to indigenous peoples and indigenous individuals. It is in that sense that the Declaration has a binding effect for the promotion, respect and fulfillment of the rights of indigenous peoples worldwide.
