Calder v British Columbia (AG)
Calder v British Columbia (AG) [1973] SCR 313, [1973] 4 WWR 1 was a decision by the Supreme Court of Canada.In 1969, Frank Arthur Calder and the Nisga'a Nation Tribal Council brought an action against the British Columbia government for a declaration that aboriginal title to certain lands in the province had never been lawfully extinguished.The Supreme Court recognized that the Nisga'a had aboriginal title to the lands at the time when European settlers arrived.The two three-justice pluralities developed competing tests for extinguishment of aboriginal title and came to differing conclusions.With this decision the government of Canada overhauled much of the land claim negotiation process with aboriginal peoples.
