statutory or constitutional construction as such and which is altogether precautionary is that the Court will declare no legislative act void unless a majority of its full membership so concurs.[292]
The cumulative effect of these limitations is difficult to measure. The limitation imposed by the case concept definitely has the effect of postponing judicial nullification, but beyond this the most that can be said is that constitutional issues affecting important issues can ordinarily be presented in a case and so will sooner or later reach the Court. The limitations of the presumptions of statutory validity, lack of concern with the wisdom of the legislation, alternative construction, separability of provisions and the like depend for their effectiveness upon the consciousness of the individual judge of the judicial proprieties and have been equally endorsed by those judges most frequently addressing themselves to the task of finding legislation invalid. The limitation imposed by the concept of political questions does not limit in any significant way the power of the federal courts to review legislation, but does remove from judicial scrutiny vast areas of executive action. In general, therefore, the extent to and manner in which the courts will exercise their power to review legislation is a matter of judicial discretion.
ALLEGATIONS OF FEDERAL QUESTION
The question of jurisdiction of cases involving federal questions is determined by the allegations made by the plaintiff and not upon the facts as they may emerge or by a decision of the merits.[293] Plaintiffs seeking to docket such cases in the federal courts must set forth a substantial claim under the Constitution, laws or treaties of the United States.[294] Nor does jurisdiction arise simply because an averment of a federal right is made, "if it plainly appears that such averment is not real and substantial, but is without color of merit."[295] The federal question averred may be insubstantial because obviously without merit, or because its unsoundness so clearly results from previous decisions of the Supreme Court as to foreclose the issue and leaves no room for the inference that the questions sought to be raised can be subjects of controversy.[296] In Gully v. First National Bank[297] the Court reviewed earlier precedents and endeavored to restate the rules for determining when a case arises. First there must be a right or immunity created by the Constitution, laws, or treaties of the United States which must be such that it will be supported if the Constitution, laws, or treaties are given one construction, or defeated if given another. Second, a genuine and present controversy as distinguished from a possible or conjectural one must exist with reference to the federal right. Third, the controversy must be disclosed upon the face of the complaint unaided by the answer.[298]
