Constitutional Law in 1927–1928: The Constitutional Decisions of the Supreme Court of the United States in the October Term, 1927

A protective tariff is constitutional. While most of us—Democratic party platforms to the contrary notwithstanding—had suspected that this was true, the Supreme Court, curiously enough, never passed on the question until its decision in Hampton v. United States. In that case the plaintiffs attacked the validity of the Tariff Act of 1922 on two grounds. In the first place, the so-called flexible tariff provision embodied in Section 315 was alleged to authorize an unconstitutional delegation of legislative power to the President. That section provides, in substance, that when the President, upon investigation, finds that differences in the cost of production here and abroad of articles produced in this country are not equalized by the tariff duties fixed by the act, he shall thereupon fix such new rates as will equalize these differences. The Court had no difficulty in rejecting this contention under the authority of Field v. Clark, in which the reciprocity sections of the Tariff Act of 1890 were sustained. Chief Justice Taft, speaking for a unanimous Court, reviews the general theory of the separation of powers and the doctrine that legislative power may not be delegated. He emphasizes, however, that each department may properly call upon the others for assistance “so far as the action invoked shall not be an assumption of the constitutional field of action of another branch.†The scope and character of this assistance, furthermore, “must be fixed according to common sense and the inherent necessities of the governmental coördination.â€
