To be a Treaty Tribe they must cite a specific treaty which includes them such as: Treaty With The Nisqualli, Puyallup, etc., 1854. pp 661-664
or
Treaty of Neah Bay, 1855
Else they are just another tribe whose existence is Federally but not Constitutionally recognized.
Federal recognition entitles a tribe to certain benefits; a Treaty Tribe has legal and Constitutional Rights. There is a vast difference.
Good point. Unfortunately, much of what is Constitutionally recognized can be unrecognized by as little as one warped federalista judge . . . until and if it works its way to the supreme court.
