R. v. Sioui
In R. v. Sioui, known as the Sioui Decision, Sioui won a unanimous decision at the Supreme Court of Canada in 1991. The ruling acknowledged that a 1760 document signed between British General James Murray and the Huron band, the Huron-British Treaty of 1760, is still valid as it was an international agreement entered into between sovereign nations.
