THE CHIEF JUSTICE delivered the opinion of the Court with respect to Parts I and II–A–1:
Article I, Section 8, of the Constitution specifies that “The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises.” The Framers recognized the unique importance of this taxing power—a power which “very clear[ly]” includes the power to impose tariffs. Gibbons v. Ogden, 9 Wheat. 1, 201. And they gave Congress “alone . . . access to the pockets of the people.” The Federalist No. 48, p.310 (J. Madison). The Framers did not vest any part of the taxing power in the Executive Branch. See Nicol v. Ames, 173 U. S. 509, 515.
