The people of the United States, by the constitution, established a national government, with sovereign powers, legislative, executive, and judicial.—Juilliard vs. Greenman, 110 U. S. Reports, p. 438.
Also it calls the constitution:
A constitution, establishing a form of government, declaring fundamental principles, and creating a national sovereignty, intended to endure for ages.—p. 439.

The power, as incident to the power of borrowing money, and issuing bills or notes of the government for money borrowed, of impressing upon those bills or notes the quality of being a legal tender for the payment of private debts, was a power universally understood to belong to sovereignty, in Europe and America, at the time of the framing and adoption of the constitution of the United States. The governments of Europe, acting through the monarch, or the legislature, according to the distribution of powers under their respective constitutions, had, and have, as sovereign a power of issuing paper money as of stamping coin. This power has been distinctly recognized in an important modern case, ably argued and fully considered, in which the Emperor of Austria, as King of Hungary, obtained from the English Court of Chancery an injunction against the issue, in England, without his license, of notes purporting to be public paper money of Hungary.—p. 447.
