As already indicated, however, the nature and effect of a statute must ordinarily be determined from the form and contents of the act itself, rather than from outside sources, and the measure under consideration purports to be a revenue act. In the light of the decisions and principles of interpretation to which reference has been made, the case against the constitutionality of the act may seem well-nigh hopeless. The fact remains, however, that Congress has not met the fundamental objection raised by the Supreme Court. The Court declared the former act unconstitutional, not only because it transcended the power of Congress under the particular provision of the Constitution then invoked, viz., the Commerce Clause, but also on the broad ground of state rights, because it "exerts a power as to a purely local matter to which the federal authority does not extend." It is difficult to see how this objection is obviated by reënacting the act as a revenue measure. Under the circumstances perhaps the apprehensive foes of federal encroachment should withhold their lamentations until the Supreme Court has spoken again.[1] [Footnote 1: Since this chapter was put into print the Court has spoken. In _Bailey v. The Drexel Furniture Co._ (decided May 15, 1922) the Child Labor Tax Law was pronounced unconstitutional. The Court, while conceding that it must interpret the intent and meaning of Congress from the language of the act, held that the act on its face is an attempt to regulate matters of state concern by the use of a so-called tax as a penalty. The opinion of the Court, written by Chief Justice Taft, is an emphatic assertion of the duty and function of the Court to preserve the constitutional equilibrium between nation and states.] VII STATE RIGHTS AND THE SUPREME COURT A century ago the United States Supreme Court was the bulwark of national power against the assaults and pretensions of the states. To-day it is the defender of the states against the encroachments of national power. Let no one suppose, however, that this is because the Court itself has faced about. On our revolving planet a ship may be sailing toward the sun at sunrise and away from the sun in the afternoon without having changed its course. The Supreme Court has been the most consistent factor in our governmental scheme. While there have been differences of viewpoint between liberal constructionists and strict constructionists among its members, the Court on the whole has steered a fairly straight course. What has really altered is the environment in which the Court moves. The earth has been turning on its axis. The frame of mind of the people who compose states and nation has changed.
