The scope of the national spending power was brought before the Supreme Court at least five times prior to 1936, but the Court disposed of four of them without construing the "general welfare" clause. In the Pacific Railway Cases[282] and Smith _v._ Kansas City Title and Trust Company,[283] it affirmed the power of Congress to construct internal improvements, and to charter and purchase the capital stock of federal land banks, by reference to the powers of the National Government over commerce, the post roads and fiscal operations, and to its war powers. Decisions on the merits were withheld in two other cases--Massachusetts _v._ Mellon and Frothingham _v._ Mellon[284]--on the ground that neither a State nor an individual citizen is entitled to a remedy in the courts against an unconstitutional appropriation of national funds. In United States _v._ Gettysburg Electric Railway Co.,[285] however, the Court had invoked "the great power of taxation to be exercised for the common defence and the general welfare,"[286] to sustain the right of the Federal Government to acquire land within a State for use as a national park. Finally, in United States _v._ Butler,[287] the Court gave its unqualified endorsement to Hamilton's views on the taxing power. Wrote Justice Roberts for the Court: "Since the foundation of the Nation sharp differences of opinion have persisted as to the true interpretation of the phrase. Madison asserted it amounted to no more than a reference to the other powers enumerated in the subsequent clauses of the same section; that, as the United States is a government of limited and enumerated powers, the grant of power to tax and spend for the general national welfare must be confined to the enumerated legislative fields committed to the Congress. In this view the phrase is mere tautology, for taxation and appropriation are or may be necessary incidents of the exercise of any of the enumerated legislative powers. Hamilton, on the other hand, maintained the clause confers a power separate and distinct from those later enumerated, is not restricted in meaning by the grant of them, and Congress consequently has a substantive power to tax and to appropriate, limited only by the requirement that it shall be exercised to provide for the general welfare of the United States. Each contention has had the support of those whose views are entitled to weight. This court had noticed the question, but has never found it necessary to decide which is the true construction. Justice Story, in his Commentaries, espouses the Hamiltonian position. We shall not review the writings of public men and commentators or discuss the legislative practice. Study of all these leads us to conclude that the reading advocated by Justice Story is the correct one. While, therefore, the power to tax is not unlimited, its confines are set in the clause which confers it, and not in those of Sec. 8 which bestow and define the legislative powers of the Congress.
