The Tsilhqot'in Nation has never surrendered or ceded their lands.
The Tsilhqot'in Nation began legal proceedings against British Columbia in 1989 to stop the harvesting of timber in the Tachelach'ed (Brittany Triangle) and the Trapline Territory (geographically known as the Tsilhqot'in Claim Area).
The Judgement by Justice Vickers was proof of Aboriginal title and called to questions the legitimacy of Provincial government licensing policies within Tsilhqot'in territory.
In 2010 the Tsilhqot'in Nation appealed the ruling by Justice Vickers and in 2012 appealed the BC court of Appeal's judgment.
On June 26, 2014 the Supreme Court of Canada declared the Tsilhqot'in Nation aboriginal title to the proven title area and further declared that British Columbia breached its duty to consult with the Tsilhqot'in in its planning and forestry authorizations.
