DOCTRINAL BACKGROUND; WEBSTER'S CONTRIBUTION
The earliest, and the most successful, attempt to set forth a principle capable of guiding the Court in adjusting the powers of the States to unexercised power of Congress under the commerce clause was that which was made by Daniel Webster in his argument in Gibbons v. Ogden, in the following words: "He contended, * * *, that the people intended, in establishing the Constitution, to transfer from the several States to a general government, those high and important powers over commerce, which, in their exercise, were to maintain a uniform and general system. From the very nature of the case, these powers must be exclusive; that is, the higher branches of commercial regulation must be exclusively committed to a single hand. What is it that is to be regulated? Not the commerce of the several States, respectively, but the commerce of the United States. Henceforth, the commerce of the States was to be a unit; and the system by which it was to exist and be governed, must necessarily be complete, entire and uniform." At the same time Webster conceded "that the words used in the Constitution, 'to regulate commerce,' are so very general and extensive, that they might be construed to cover a vast field of legislation, part of which has always been occupied by State laws; and therefore, the words must have a reasonable construction, and the power should be considered as exclusively vested in Congress, so far, and so far only, as the nature of the power requires."[527]
Webster also dealt with the problem which arises when Congress has exercised its power. The results of its act, he contended, must be treated as a unit, so that when Congress had left subject matter within its jurisdiction unregulated, it must be deemed to have done so of design, and its omissions, or silences, accordingly be left undisturbed by State action. Although Marshall, because he thought the New York act creating the Livingston-Fulton monopoly to be in direct conflict with the Enrolling and Licensing Act of 1793, was not compelled to pass on either of Webster's theories, he indicated his sympathy with them.[528]
COOLEY v. BOARD OF PORT WARDENS
Aside from Marshall's opinion in 1827 in Brown v. Maryland,[529] in which the famous "original package" formula made its debut, the most important utterance of the Court touching interpretation of the commerce clause as a restriction on State legislative power is that for which Cooley v. Board of Wardens of Port of Philadelphia,[530] decided in 1851, is usually cited. The question at issue was the validity of a Pennsylvania pilotage act so far as it applied to vessels engaged in foreign commerce and the coastwise trade. The Court, speaking through Justice Curtis, sustained the act on the basis of a distinction between those subjects of commerce which "imperatively demand a single uniform rule" operating throughout the country and those which "as imperatively" demand "that diversity which alone can meet the local necessities of navigation," that is to say, of commerce. As to the former the Court held Congress's power to be "exclusive"—as to the latter it held that the States enjoyed a power of "concurrent legislation."
While this formula obviously stems directly from Webster's argument in Gibbons v. Ogden, it covers considerably less ground. Citation, nevertheless, of the Cooley case throughout the next half century eliminated the difference and brought the Curtis dictum abreast of Webster's earlier argument. The doctrine consequently came to be established, first, that Congress's power over interstate commerce is "exclusive" as to those phases of it which require "uniform regulation"; second, that outside this field, as plotted by the Court, the States enjoyed a "concurrent" power of regulation, subject to Congress's overriding power.[531]
JUDICIAL FORMULAS
But meantime other formulas had emerged from the judicial smithy, several of which are brought together into something like a doctrinal system, in Justice Hughes' comprehensive opinion for the Court in the Minnesota Rate Cases,[532] decided in 1913. "Direct" regulation of foreign or interstate commerce by a State is here held to be out of the question. At the same time, the States have their police and taxing powers, and may use them as their own views of sound public policy may dictate even though interstate commerce may be "incidentally" or "indirectly" regulated, it being understood that such "incidental" or "indirect" effects are always subject to Congressional disallowance. "Our system of government," Justice Hughes reflects, "is a practical adjustment by which the National authority as conferred by the Constitution is maintained in its fall scope without unnecessary loss of local efficiency."[533]
In more concrete terms, the varied formulas which characterize this branch of our Constitutional Law have been devised by the Court from time to time in an endeavor to effect "a practical adjustment" between two great interests, the maintenance of freedom of commerce except so far as Congress may choose to restrain it, and the maintenance in the States of efficient local governments. Thus, while formulas may serve to steady and guide its judgment, the Court's real function in this area of judicial review is essentially that of an arbitral or quasi-legislative body. So much so is this the case that in 1940 three Justices joined in an opinion in which they urged that the business of drawing the line between the immunity of interstate commerce and the taxing power of the States "should be left to the legislatures of the States and the Congress," with the final remedy in the hands of the latter.[534]
