Samuel Freeman Miller,
United States v. Waddell — Opinion of the Court
“ It would, indeed, be strange if the United States, under the constitutional provisions we have cited, being the owner of unsettled lands larger in area than the most powerful kingdoms of Europe, and having the power 'to dispose of and make all needful rules and regulations respecting this territory,' cannot make a law which protects a party in the performance of his existing contract for the purchase of such land, without which the contract fails, and the rights, both of the United States and the purchaser, are defeated. ”
