I want to know the answer to the following question:
What legislative act provided that no Indian nation shall be acknowledged as an independent nation with whom the United States may contract by treaty?
All the background I'm provided with is that "563) had a rider (25 U.S.C. § 71) attached that effectively ended the President’s treaty making by providing that no Indian nation or tribe shall be acknowledged as an independent nation, tribe, or power with whom the United States may contract by treaty.". Is that enough to answer the question?
Answer: no
