Account of the ground-breaking Supreme Court Case, Guerin v. the Queen, in 1984. The lawyer for the Musqueam First Nation during this legal battle provides a detailed history of the case and the meaning behind the decision that compels the federal government to act in the best interests of First Nations. The government's breach of duty to First Nations, in this case the Musqueam, is documented. The author compares Canadian law with respect to fiduciary duty with that of Australia, New Zealand and the United States.
