It's the first time natives have claimed that a treaty signed in 1899 overrules regulations contained in the National Parks Act and the game rules set by Wood Buffalo Park, said Gord Antoniuk, assistant chief park warden. [Irvin Norn] pleaded not guilty claiming Treaty Eight, signed in 1899 between the federal government and natives in the park area, supersedes the National Park Act. The treaty, which covers a large amount of land both in Alberta and Saskatchewan, gives natives the right to fish and hunt for food. Brothers Archie and Lorne Antoine and Emile, Harvey and William Gibot shot and killed nine bison. The shooting of bison by anyone, including natives, is prohibited under park regulations, Antoniuk said.
