Article 1, Section 8, Clause 3 (Indians)
James Madison, Federalist, no. 42, 284--8522 Jan. 1788
The regulation of commerce with the Indian tribes is very properly unfettered from two limitations in the articles of confederation, which render the provision obscure and contradictory. The power is there restrained to Indians, not members of any of the States, and is not to violate or infringe the legislative right of any State within its own limits. What description of Indians are to be deemed members of a State, is not yet settled; and has been a question of frequent perplexity and contention in the Foederal Councils. And how the trade with Indians, though not members of a State, yet residing within its legislative jurisdiction, can be regulated by an external authority, without so far intruding on the internal rights of legislation, is absolutely incomprehensible. This is not the only case in which the articles of confederation have inconsiderately endeavored to accomplish impossibilities; to reconcile a partial sovereignty in the Union, with compleat sovereignty in the States; to subvert a mathematical axiom, by taking away a part, and letting the whole remain.
