The United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) was adopted by the General Assembly on Thursday, 13 September 2007, by a majority of 144 states in favour, 4 votes against (Australia, Canada, New Zealand and the United States) and 11 abstentions (Azerbaijan, Bangladesh, Bhutan, Burundi, Colombia, Georgia, Kenya, Nigeria, Russian Federation, Samoa and Ukraine).
In May 2016 Canada officially removed its objector status to UNDRIP, almost a decade after it was adopted by the General Assembly. By now also the other 3 objectors have, to various degrees, turned their vote with the United states fully endorsing the UNDRIP and working on implementation with Tribes in the U.S.
While as a General Assembly Declaration it is not a legally binding instrument under international law according to a UN press release, it does "represent the dynamic development of international legal norms and it reflects the commitment of the UN's member states to move in certain directions"; the UN describes it as setting "an important standard for the treatment of indigenous peoples that will undoubtedly be a significant tool towards eliminating human rights violations against the planet's 370 million indigenous people and assisting them in combating discrimination and marginalization.
UNDRIP codifies "Indigenous historical grievances, contemporary challenges and socio-economic, political and cultural aspirations" and is the "culmination of generations-long efforts by Indigenous organizations to get international attention, to secure recognition for their aspirations, and to generate support for their political agendas. Canada Research Chair and faculty member at the University of Saskatchewan, Ken Coates, argues that UNDRIP resonates powerfully with Indigenous peoples, while national governments have not yet fully understood its impact.
