Horace Gray, The Legal-Tender Cases — Opinion of the Court
“ That clause of the constitution which declares that 'the congress shall have power to lay and collect taxes, duties, imposts, and excises, to pay the debts and provide for the common defense and general welfare of the United States,' either embodies a grant of power to pay the debts of the United States or presupposes and assumes that power as inherent in the United States as a sovereign government. ”
