While the act was thus held to be within the constitutional powers of Congress in relation to a productive concern, the interruption of whose business by strike "might be catastrophic," the decision was forthwith held to apply also to two minor concerns;[457] and in a later case the Court stated specifically that "the smallness of the volume of commerce affected in any particular case" is not a material consideration.[458] Moreover, the doctrine of the Jones-Laughlin Case applies equally to "natural" products, to coal mined, to stone quarried, to fruit and vegetables grown.[459]

THE FAIR LABOR STANDARDS ACT; THE DARBY CASE

In 1938 Congress enacted the Fair Labor Standards Act.[460] The measure prohibits not only the shipment in interstate commerce of goods manufactured by employees whose wages are less than the prescribed minimum or whose weekly hours of labor are greater than the prescribed maximum, but also the employment of workmen in the production of goods for such commerce at other than the prescribed wages and hours. Interstate commerce is defined by the act to mean "trade, commerce, transportation, transmission, or communication among the several States or from any State to any place outside thereof." It was further provided that "for the purposes of this act an employee shall be deemed to have been engaged in the production of goods [that is, for interstate commerce] if such employee was employed * * *, or in any process or occupation necessary to the production thereof, in any State." Sustaining an indictment under the act, a unanimous Court, speaking by Chief Justice Stone, said: "The motive and purpose of the present regulation are plainly to make effective the congressional conception of public policy that interstate commerce should not be made the instrument of competition in the distribution of goods produced under substandard labor conditions, which competition is injurious to the commerce and to the States from and to which commerce flows."[461] In support of the decision the Court invokes Chief Justice Marshall's reading of the necessary and proper clause in McCulloch v. Maryland and his reading of the commerce clause in Gibbons v. Ogden.[462] Objections purporting to be based on the Tenth Amendment are met from the same point of view: "Our conclusion is unaffected by the Tenth Amendment which provides: 'The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.' The amendment states but a truism that all is retained which has not been surrendered. There is nothing in the history of its adoption to suggest that it was more than declaratory of the relationship between the national and State governments as it had been established by the Constitution before the amendment or that its purpose was other than to allay fears that the new National Government might seek to exercise powers not granted, and that the States might not be able to exercise fully their reserved powers. See e.g., II Elliot's Debates, 123, 131; III id. 450, 464, 600; IV id. 140, 149; I Annals of Congress, 432, 761, 767-768; Story, Commentaries on the Constitution, Sec. 1907-1908."[463] Commenting recently on this decision, former Justice Roberts said: "Of course, the effect of sustaining the Fair Labor Standards Act was to place the whole matter of wages and hours of persons employed throughout the United States, with slight exceptions, under a single federal regulatory scheme and in this way completely to supersede state exercise of the police power in this field."[464] In a series of later cases construing terms of the act, it had been given wide application.[465]

THE AGRICULTURAL MARKETING AGREEMENT ACT

Meantime Congress had returned to the task of bolstering agriculture by passing the Agricultural Marketing Agreement Act of June 3, 1937,[466] authorizing the Secretary of Agriculture to fix the minimum prices of certain agricultural products, when the handling of such products occurs "in the current of interstate or foreign commerce or * * * directly burdens, obstructs or affects interstate or foreign commerce in such commodity or product thereof." In United States v. Wrightwood Dairy Company[467] the Court sustained an order of the Secretary of Agriculture fixing the minimum prices to be paid to producers of milk in the Chicago "marketing area." The dairy company demurred to the regulation on the ground of its applying to milk produced and sold intrastate. Sustaining the order the Court said: "Congress plainly has power to regulate the price of milk distributed through the medium of interstate commerce, * * *, and it possesses every power needed to make that regulation effective. The commerce power is not confined in its exercise to the regulation of commerce among the States. It extends to those activities intrastate which so affect interstate commerce, or the exertion of the power of Congress over it, as to make regulation of them appropriate means to the attainment of a legitimate end, the effective execution of the granted power to regulate interstate commerce. See McCulloch v. Maryland, 4 Wheat. 316, 421; * * * The power of Congress over interstate commerce is plenary and complete in itself, may be exercised to its utmost extent, and acknowledges no limitations other than are prescribed in the Constitution. Gibbons v. Ogden, 9 Wheat. 1, 196. It follows that no form of State activity can constitutionally thwart the regulatory power granted by the commerce clause to Congress. Hence the reach of that power extends to those intrastate activities which in a substantial way interfere with or obstruct the exercise of the granted power."[468]

In Wickard v. Filburn[469] a still deeper penetration by Congress into the field of production was sustained. As amended by the act of 1941, the Agricultural Adjustment Act of 1938,[470] regulates production even when not intended for commerce but wholly for consumption on the producer's farm. Sustaining this extension of the act, the Court pointed out that the effect of the statute was to support the market. It said: "It can hardly be denied that a factor of such volume and variability as home-consumed wheat would have a substantial influence on price and market conditions. This may arise because being in marketable condition such wheat overhangs the market and, if induced by rising prices, tends to flow into the market and check price increases. But if we assume that it is never marketed, it supplies a need of the man who grew it which would otherwise be reflected by purchases in the open market. Home-grown wheat in this sense competes with wheat in commerce. The stimulation of commerce is a use of the regulatory function quite as definitely as prohibitions or restrictions thereon. This record leaves us in no doubt that Congress may properly have considered that wheat consumed on the farm where grown, if wholly outside the scheme of regulation, would have a substantial effect in defeating and obstructing its purpose to stimulate trade therein at increased prices."[471] And it elsewhere stated: "Questions of the power of Congress are not to be decided by reference to any formula which would give controlling force to nomenclature such as 'production' and 'indirect' and foreclose consideration of the actual effects of the activity in question upon interstate commerce. * * * The Court's recognition of the relevance of the economic effects in the application of the Commerce Clause, * * *, has made the mechanical application of legal formulas no longer feasible."[472]

Acts of Congress Prohibiting Commerce

FOREIGN COMMERCE; JEFFERSON'S EMBARGO

"Jefferson's Embargo" of 1807-1808, which cut all trade with Europe, was attacked on the ground that the power to regulate commerce was the power to preserve it, not the power to destroy it. This argument was rejected by Judge Davis of the United States District Court for Massachusetts in the following words: "A national sovereignty is created [by the Constitution]. Not an unlimited sovereignty, but a sovereignty, as to the objects surrendered and specified, limited only by the qualifications and restrictions, expressed in the Constitution. Commerce is one of those objects. The care, protection, management and control, of this great national concern, is, in my opinion, vested by the Constitution, in the Congress of the United States; and their power is sovereign, relative to commercial intercourse, qualified by the limitations and restrictions, expressed in that instrument, and by the treaty making power of the President and Senate. * * * Power to regulate, it is said, cannot be understood to give a power to annihilate. To this it may be replied, that the acts under consideration, though of very ample extent, do not operate as a prohibition of all foreign commerce. It will be admitted that partial prohibitions are authorized by the expression; and how shall the degree, or extent, of the prohibition be adjusted, but by the discretion of the National Government, to whom the subject appears to be committed? * * * The term does not necessarily include shipping or navigation; much less does it include the fisheries. Yet it never has been contended, that they are not the proper objects of national regulation; and several acts of Congress have been made respecting them. * * * [Furthermore] if it be admitted that national regulations relative to commerce, may apply it as an instrument, and are not necessarily confined to its direct aid and advancement, the sphere of legislative discretion is, of course, more widely extended; and, in time of war, or of great impending peril, it must take a still more expanded range. Congress has power to declare war. It, of course, has power to prepare for war; and the time, the manner, and the measure, in the application of constitutional means, seem to be left to its wisdom and discretion. * * * Under the Confederation, * * * we find an express reservation to the State legislatures of the power to pass prohibitory commercial laws, and, as respects exportations, without any limitations. Some of them exercised this power. * * * Unless Congress, by the Constitution, possess the power in question, it still exists in the State legislatures—but this has never been claimed or pretended, since the adoption of the federal Constitution; and the exercise of such a power by the States, would be manifestly inconsistent with the power, vested by the people in Congress, 'to regulate commerce.' Hence I infer, that the power, reserved to the States by the articles of Confederation, is surrendered to Congress, by the Constitution; unless we suppose, that, by some strange process, it has been merged or extinguished, and now exists no where."[473]

FOREIGN COMMERCE; PROTECTIVE TARIFFS

Tariff laws have customarily contained prohibitory provisions, and such provisions have been sustained by the Court under Congress's revenue powers (see above) and under its power to regulate foreign commerce. Speaking for the Court in University of Illinois v. United States,[474] in 1933, Chief Justice Hughes said: "The Congress may determine what articles may be imported into this country and the terms upon which importation is permitted. No one can be said to have a vested right to carry on foreign commerce with the United States. * * * It is true that the taxing power is a distinct power; that it is distinct from the power to regulate commerce. * * * It is also true that the taxing power embraces the power to lay duties. Art. I, Sec. 8, cl. 1. But because the taxing power is a distinct power and embraces the power to lay duties, it does not follow that duties may not be imposed in the exercise of the power to regulate commerce. The contrary is well established. Gibbons v. Ogden, 9 Wheat. 1, 202. 'Under the power to regulate foreign commerce Congress impose duties on importations, give drawbacks, pass embargo and nonintercourse laws, and make all other regulations necessary to navigation, to the safety of passengers, and the protection of property.' Groves v. Slaughter, 15 Pet. 449, 505. The laying of duties is 'a common means of executing the power.' 2 Story on the Constitution, Sec. 1088."[475]

FOREIGN COMMERCE; BANNED ARTICLES

The forerunners of more recent acts excluding objectionable commodities from interstate commerce are the laws forbidding the importation of like commodities from abroad. This power Congress has exercised since 1842. In that year it forbade the importation of obscene literature or pictures from abroad.[476] Six years later it passed an act "to prevent the importation of spurious and adulterated drugs" and to provide a system of inspection to make the prohibition effective.[477] Such legislation guarding against the importation of noxiously adulterated foods, drugs, or liquor has been on the statute books ever since. In 1887 the importation by Chinese nationals of smoking opium was prohibited,[478] and subsequent statutes passed in 1909 and 1914 made it unlawful for anyone to import it.[479] In 1897 Congress forbade the importation of any tea "inferior in purity, quality, and fitness for consumption" as compared with a legal standard.[480] The act was sustained in 1904, in the leading case of Buttfield v. Stranahan.[481] In "The Abby Dodge" case an act excluding sponges taken by means of diving or diving apparatus from the waters of the Gulf of Mexico or Straits of Florida was sustained, but construed as not applying to sponges taken from the territorial waters of a State.[482] In Weber v. Freed[483] an act prohibiting the importation and interstate transportation of prize-fight films or of pictorial representation of prize fights was upheld. Speaking for the unanimous Court, Chief Justice White said: "In view of the complete power of Congress over foreign commerce and its authority to prohibit the introduction of foreign articles recognized and enforced by many previous decisions of this court, the contentions are so devoid of merit as to cause them to be frivolous."[484] In Brolan v. United States[485] the Court again stressed the absolute nature of Congress's power over foreign commerce, saying: "In the argument reference is made to decisions of this court dealing with the subject of the power of Congress to regulate interstate commerce, but the very postulate upon which the authority of Congress to absolutely prohibit foreign importations as expounded by the decisions of this court rests is the broad distinction which exists between the two powers and therefore the cases cited and many more which might be cited announcing the principles which they uphold have obviously no relation to the question in hand."[486]

INTERSTATE COMMERCE; CONFLICT OF DOCTRINE AND OPINION

The question whether Congress's power to regulate commerce "among the several States" embraced the power to prohibit it furnished the topic of one of the most protracted debates in the entire history of the Constitution's interpretation, a debate the final resolution of which in favor of Congressional power is an event of first importance for the future of American Federalism. The issue was as early as 1841 brought forward by Henry Clay, in an argument before the Court in which he raised the specter of an act of Congress forbidding the interstate slave trade.[487] The debate was concluded ninety-nine years later by the decision in United States v. Darby, in which the Fair Labor Standards Act was sustained. The resume of it which is given below is based on judicial opinions, arguments of counsel, and the writings of jurists and political scientists. Much of this material was evoked by efforts of Congress, from about 1905 onward, to stop the shipment interstate of the products of child labor.

ACTS OF CONGRESS PROHIBITIVE OF INTERSTATE COMMERCE

The earliest such acts were in the nature of quarantine regulations and usually dealt solely with interstate transportation. In 1884 the exportation or shipment in interstate commerce of livestock having any infectious disease was forbidden.[488] In 1903 power was conferred upon the Secretary of Agriculture to establish regulations to prevent the spread of such diseases through foreign or interstate commerce.[489] In 1905 the same official was authorized to lay an absolute embargo or quarantine upon all shipments of cattle from one State to another when the public necessity might demand it.[490] A statute passed in 1905 forbade the transportation in foreign and interstate commerce and the mails of certain varieties of moths, plant lice, and other insect pests injurious to plant crops, trees, and other vegetation.[491] In 1912 a similar exclusion of diseased nursery stock was decreed,[492] while by the same act, and again by an act of 1917,[493] the Secretary of Agriculture was invested with powers of quarantine on interstate commerce for the protection of plant life from disease similar to those above described for the prevention of the spread of animal disease. While the Supreme Court originally held federal quarantine regulations of this sort to be constitutionally inapplicable to intrastate shipments of livestock, on the ground that federal authority extends only to foreign and interstate commerce,[494] this view has today been abandoned. See pp. 248-249.

THE LOTTERY CASE

The first case to come before the Court in which the issues discussed above were canvassed at all thoroughly was Champion v. Ames,[495] involving the act of 1895 "for the suppression of lotteries."[496] An earlier act excluding lottery tickets from the mails had been upheld in the earlier case of In re Rapier,[497] on the proposition that Congress clearly had the power to see that the very facilities furnished by it were not put to bad uses. But in the case of commerce the facilities are not ordinarily furnished by the National Government, and the right to engage in foreign and interstate commerce comes from the Constitution itself, or is anterior to it.

How difficult the Court found the question produced by the act of 1895, forbidding any person to bring within the United States or to cause to be "carried from one State to another" any lottery ticket, or an equivalent thereof, "for the purpose of disposing of the same," is shown by the fact that the case was thrice argued before the Court, and the fact that the Court's decision finally sustaining the act was a five-to-four decision. The opinion of the Court, on the other hand, prepared by Justice Harlan, marked an almost unqualified triumph at the time for the view that Congress's power to regulate commerce among the States includes the power to prohibit it, especially to supplement and support State legislation enacted under the police power.[498] Early in the opinion extensive quotation is made from Chief Justice Marshall's opinion in Gibbons v. Ogden,[499] with special stress upon the definition there given of the phrase "to regulate." Justice Johnson's assertion on the same occasion is also given: "The power of a sovereign State over commerce, * * *, amounts to nothing more than, a power to limit and restrain it at pleasure." Further along is quoted with evident approval Justice Bradley's statement in Brown v. Houston,[500] that "the power to regulate commerce among the several States is granted to Congress in terms as absolute as is the power to regulate commerce with foreign nations."

NATIONAL PROHIBITIONS AND STATE POLICE POWER

Following in the wake of Champion v. Ames, Congress has repeatedly brought its prohibitory powers over interstate commerce and communications to the support of certain local policies of the States in the exercise of their reserved powers, thereby aiding them in the repression of the liquor traffic,[501] of traffic in game taken in violation of State laws,[502] of commerce in convict-made goods,[503] of the white slave traffic,[504] of traffic in stolen motor vehicles,[505] of kidnapping,[506] of traffic in stolen property,[507] of racketeering,[508] of prize-fight films or other pictorial representation of encounters of pugilists.[509] The conception of the Federal System on which the Court based its validation of this legislation was stated by it in 1913 in sustaining the Mann "White Slave" Act in the following words: "Our dual form of government has its perplexities, State and Nation having different spheres of jurisdiction, * * *, but it must be kept in mind that we are one people; and the powers reserved to the States and those conferred on the Nation are adapted to be exercised, whether independently or concurrently, to promote the general welfare, material, and moral."[510] At the same time, the Court made it plain that in prohibiting commerce among the States, Congress was equally free to support State legislative policy or to devise a policy of its own. "Congress," it said, "may exercise this authority in aid of the policy of the State, if it sees fit to do so. It is equally clear that the policy of Congress acting independently of the States may induce legislation without reference to the particular policy or law of any given State. Acting within the authority conferred by the Constitution it is for Congress to determine what legislation will attain its purposes. The control of Congress over interstate commerce is not to be limited by State laws."[511]

HAMMER v. DAGENHART

However, it is to be noted that none of this legislation operated in the field of industrial relations. So when the Court was confronted in 1918, in the case of Hammer v. Dagenhart,[512] with an act which forbade manufacturers and others to offer child-made goods for transportation in interstate commerce,[513] it held the act, by the narrow vote of five Justices to four, to be not an act regulative of commerce among the States, but one which invaded the reserved powers of the States. "The maintenance of the authority of the States over matters purely local," said Justice Day for the Court, "is as essential to the preservation of our institutions as is the conservation of the supremacy of the federal power in all matters entrusted to the Nation by the Federal Constitution."[514] As to earlier decisions sustaining Congress's prohibitory powers, Justice Day said: "In each of these instances the use of interstate transportation was necessary to the accomplishment of harmful results. * * * This element is wanting in the present case. * * * The goods shipped are in themselves harmless. * * * When offered for shipment, and before transportation begins, the labor of their production is over, and the mere fact that they were intended for interstate commerce transportation does not make their production subject to federal control under the commerce power. * * * 'When commerce begins is determined, not by the character of the commodity, nor by the intention of the owner to transfer it to another State for sale, * * *, but by its actual delivery to a common carrier for transportation, * * *' (Mr. Justice Jackson in In re Greene, 52 Fed. Rep. 113). This principle has been recognized often in this court. Coe v. Errol, 116 U.S. 517 * * *."[515]

The decision in Hammer v. Dagenhart was, in short, governed by the same general conception of the interstate commerce process as that which governed the decision in the Sugar Trust Case. Commerce was envisaged as beginning only with an act of transportation from one State to another. And from this it was deduced that the only commerce which Congress may prohibit is an act of transportation from one State to the other which is followed in the latter by an act within the normal powers of government to prohibit. Commerce, however, is primarily traffic; and the theory of the Child Labor Act was that it was designed to discourage a widespread and pernicious interstate traffic in the products of child labor—pernicious because it bore "a real and substantial relation" to the existence of child labor employment in some States and constituted a direct inducement to its spread to other States. Deprived of the interstate market which this decision secured to it, child labor could not exist.

INTERSTATE COMMERCE IN STOLEN GOODS BANNED

In Brooks v. United States,[516] decided in 1925, the Court, in sustaining the National Motor Vehicle Theft Act of 1919,[517] materially impaired the ratio decidendi of Hammer v. Dagenhart. At the outset of his opinion for the Court, Chief Justice Taft stated the general proposition that "Congress can certainly regulate interstate commerce to the extent of forbidding and punishing the use of such commerce as an agency to promote immorality, dishonesty or the spread of any evil or harm to the people of other States from the State of origin." This statement was buttressed by a review of previous cases, including the explanation that the goods involved in Hammer v. Dagenhart were "harmless" and did not spread harm to persons in other States. Passing then to the measure before the Court, the Chief Justice noted "the radical change in transportation" brought about by the automobile, and the rise of "elaborately organized conspiracies for the theft of automobiles * * *, and their sale or other disposition" in another police jurisdiction from the owner's. This, the opinion declared, "is a gross misuse of interstate commerce. Congress may properly punish such interstate transportation by anyone with knowledge of the theft, because of its harmful result and its defeat of the property rights of those whose machines against their will are taken into other jurisdictions."[518]

The Motor Vehicle Act was sustained, therefore, mainly as protective of owners of automobiles, that is to say, of interests in "the State of origin." It was designed to repress automobile thefts, and that notwithstanding the obvious fact that such thefts must necessarily occur before transportation of the thing stolen can take place, that is, under the formula followed in Hammer v. Dagenhart, before Congress's power over interstate commerce becomes operative. Also, the Court took cognizance of "elaborately organized conspiracies" for the theft and disposal of automobiles across State lines—that, to say, of a widespread traffic in such property.

THE DARBY CASE

The formal overruling of Hammer v. Dagenhart, however, did not occur until 1941 when, in sustaining the Fair Labor Standards Act, a unanimous Court, speaking by Justice Stone, said: "Hammer v. Dagenhart has not been followed. The distinction on which the decision was rested that Congressional power to prohibit interstate commerce is limited to articles which in themselves have some harmful or deleterious property—a distinction which was novel when made and unsupported by any provision of the Constitution—has long since been abandoned. * * * The thesis of the opinion that the motive of the prohibition or its effect to control in some measure the use or production within the States of the article thus excluded from the commerce can operate to deprive the regulation of its constitutional authority has long since ceased to have force. * * * And finally we have declared 'The authority of the Federal Government over interstate commerce does not differ in extent or character from that retained by the States over intrastate commerce.' United States v. Rock Royal Co-operative, 307 U.S. 533, 569. The conclusion is inescapable that Hammer v. Dagenhart, was a departure from the principles which have prevailed in the interpretation of the Commerce Clause both before and since the decision and that such vitality, as a precedent, as it then had has long since been exhausted. It should be and now is overruled."[519] And commenting in a recent case on the Fair Labor Standards Act, Justice Burton, speaking for the Court said: "The primary purpose of the act is not so much to regulate interstate commerce as such, as it is, through the exercise of legislative power, to prohibit the shipment of goods in interstate commerce if they are produced under substandard labor conditions."[520]

CONGRESS AND THE FEDERAL SYSTEM

In view of these developments the following dictum by Justice Frankfurter, was no doubt, intended to be reassuring as to the future of the Federal System: "The interpenetrations of modern society have not wiped out State lines. It is not for us [the Court] to make inroads upon our federal system either by indifference to its maintenance or excessive regard for the unifying forces of modern technology. Scholastic reasoning may prove that no activity is isolated within the boundaries of a single State, but that cannot justify absorption of legislative power by the United States over every activity."[521] While this may be conceded, the unmistakable lesson of recent cases is that the preservation of our Federal System depends today mainly upon Congress.

The Commerce Clause as a Restraint on State Powers

DOCTRINAL BACKGROUND

The grant of power to Congress over commerce, unlike that of power to levy customs duties, the power to raise armies, and some others, is unaccompanied by correlative restrictions on State power. This circumstance does not, however, of itself signify that the States were expected still to participate in the power thus granted Congress, subject only to the operation of the supremacy clause. As Hamilton points out in The Federalist, while some of the powers which are vested in the National Government admit of their "concurrent" exercise by the States, others are of their very nature "exclusive," and hence render the notion of a like power in the States "contradictory and repugnant."[522] As an example of the latter kind of power Hamilton mentioned the power of Congress to pass a uniform naturalization law. Was the same principle expected to apply to the power over foreign and interstate commerce?

Unquestionably one of the great advantages anticipated from the grant to Congress of power over commerce was that State interferences with trade, which had become a source of sharp discontent under the Articles of Confederation, would be thereby brought to an end. As Webster stated in his argument for appellant in Gibbons v. Ogden: "The prevailing motive was to regulate commerce; to rescue it from the embarrassing and destructive consequences, resulting from the legislation of so many different States, and to place it under the protection of a uniform law." In other words, the constitutional grant was itself a regulation of commerce in the interest of uniformity. Justice Johnson's testimony in his concurring opinion in the same case is to like effect: "There was not a State in the Union, in which there did not, at that time, exist a variety of commercial regulations; * * * By common consent, those laws dropped lifeless from their statute books, for want of sustaining power that had been relinquished to Congress";[523] and Madison's assertion, late in life, that power had been granted Congress over interstate commerce mainly as "a negative and preventive provision against injustice among the States,"[524] carries a like implication.

That, however, the commerce clause, unimplemented by Congressional legislation, took from the States any and all power over foreign and interstate commerce was by no means universally conceded; and Ogden's attorneys directly challenged the idea. Moreover, as was pointed out on both sides in Gibbons v. Ogden, legislation by Congress regulative of any particular phase of commerce would still leave many other phases unregulated and consequently raise the question whether the States were entitled to fill the remaining gaps, if not by virtue of a "concurrent" power over interstate and foreign commerce, then by virtue of "that immense mass of legislation," as Marshall termed it, "which embraces everything within the territory of a State, not surrendered to the general government,"[525]—in a word, the "police power."

The commerce clause does not, therefore, without more ado, settle the question of what power is left to the States to adopt legislation regulating foreign or interstate commerce in greater or less measure. To be sure, in cases of flat conflict between an act or acts of Congress regulative of such commerce and a State legislative act or acts, from whatever State power ensuing, the act of Congress is today recognized, and was recognized by Marshall, as enjoying an unquestionable supremacy.[526] But suppose, first, that Congress has passed no act; or secondly, that its legislation does not clearly cover the ground which certain State legislation before the Court attempts to cover—what rules then apply? Since Gibbons v. Ogden both of these situations have confronted the Court, especially as regards interstate commerce, hundreds of times, and in meeting them the Court has, first and last, coined or given currency to numerous formulas, some of which still guide, even when they do not govern, its judgment.

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]

State Taxing Power and Foreign Commerce

BROWN v. MARYLAND; THE ORIGINAL PACKAGE DOCTRINE

The leading case under this heading is Brown v. Maryland,[535] decided in 1827, the issue in which was the validity of a Maryland statute requiring "all importers of foreign articles or commodities," preparatory to selling the same, to take out a license. Holding this act to be void under both article I, sec. 10, and the commerce clause, the Court, speaking through Chief Justice Marshall, advanced the following propositions: (1) that "commerce is intercourse; one of its most ordinary ingredients is traffic"; (2) that the right to import includes the right to sell; (3) that a tax on the sale of an article is a tax on the article itself—a conception of the incidence of taxation which has at times had important repercussions in other fields of Constitutional Law; (4) that the taxing power of the State does not extend in any form to imports from abroad so long as they remain "the property of the importer, in his warehouse, in the original form or package" in which they were imported—the famous "original package doctrine"; (5) that once, however, the importer parts with his importations "or otherwise mixes them with the general property of the State by breaking up his packages," the law may treat them as part and parcel of such property; (6) that even while in the original package imports are subject to the incidental operation of police measures adopted by the State in good faith for the protection of the public against apparent dangers. Lastly, in determining whether a State law amounts to a regulation of commerce the Court would, Marshall announced, be guided by "substance" and not by "form"—a proposition which has many times opened the way to extensive inquiries by the Court into the actualities both of commercial practice and of State administration.

The decision in Brown v. Maryland, but more especially the "original package doctrine" there laid down, has been sometimes criticised as going too far. It would have been sufficient, the critics contend, for the Court to have held the Maryland act void on account of its obviously discriminatory character; and they urge that original packages receiving the protection of the State ought to be subject to nondiscriminatory taxation by it. The criticism was partially anticipated by Marshall himself in the apprehensions which he voiced that any concession to "the great importing States" might be turned by them against the rest of the country. Indeed, he is uncertain whether the original package doctrine will prove sufficient for its purposes and accordingly offers it not as a rule "universal in its application," but rather as a stop-gap principle. History has proved, however, that in this he builded better than he knew. For in the field of foreign commerce the original package doctrine has never been disturbed, and it has scarcely been added to; and so confined, it has never been surpassed by any later piece of judicial legislation, whether in point of durability or in that of definiteness and easy comprehensibility.[536]

State Taxation of the Subject Matter of Interstate Commerce

GENERAL CONSIDERATIONS

The task of drawing the line between State power and the commercial interest has proved a comparatively simple one in the field of foreign commerce, the two things being in great part territorially distinct. With "commerce among the States" it is very different. This is conducted in the interior of the country, by persons and corporations that are ordinarily engaged also in local business; its usual incidents are acts which, if unconnected with commerce among the States, would fall within the State's powers of police and taxation; while the things it deals in and the instruments by which it is carried on comprise the most ordinary subject matter of State power. In this field the Court has, consequently, been unable to rely upon sweeping solutions. To the contrary, its judgments have often been fluctuating and tentative, even contradictory; and this is particularly the case as respects the infringement of the State taxing power on interstate commerce. In the words of Justice Frankfurter: "The power of the States to tax and the limitations upon that power imposed by the Commerce Clause have necessitated a long, continuous process of judicial adjustment. The need for such adjustment is inherent in a Federal Government like ours, where the same transaction has aspects that may concern the interests and involve the authority of both the central government and the constituent States. The history of this problem is spread over hundreds of volumes of our Reports. To attempt to harmonize all that has been said in the past would neither clarify what has gone before nor guide the future. Suffice it to say that especially in this field opinions must be read in the setting of the particular cases and as the product of preoccupation with their special facts."[537]

THE STATE FREIGHT TAX CASE

The great leading case dealing with the relation of the State's taxing power to interstate commerce is that of the State Freight Tax,[538] decided in 1873. The question before the Court was the validity of a Pennsylvania statute, passed eight years earlier, which required every company transporting freight within the State, with certain exceptions, to pay a tax at specified rates on each ton of freight carried by it. Overturning the act, the Court held: "(1) The transportation of freight, or of the subjects of commerce, is a constituent part of commerce itself; (2) a tax upon freight, transported from State to State, is a regulation of commerce among the States; (3) whenever the subjects in regard to which a power to regulate commerce is asserted are in their nature National, or admit of one uniform system or plan of regulation, they are exclusively within the regulating control of Congress; (4) transportation of passengers or merchandise through a State, or from one State to another, is of this nature; (5) hence a statute of a State imposing a tax upon freight, taken up within the State and carried out of it, or taken up without the State and brought within it, is repugnant to that provision of the Constitution of the United States, which ordains that 'Congress shall have power to regulate commerce with foreign nations and among the several States, and with the Indian tribes.'"[539]

GOODS IN TRANSIT

States, therefore, may not tax property in transit in interstate commerce. A nondiscriminatory tax, however, is permitted if the goods have not yet started in interstate commerce, or have completed the interstate transit even though still in the original package, unless they are foreign imports in the original package; and States may also impose a nondiscriminatory tax when there is a break in an interstate transit, and the goods have not been restored to the current of interstate commerce. Such is the law in brief. Two questions arise, first, when do goods originating in a State pass from under its power to tax; and, second, when do goods arriving from another State lose their immunity?

The leading case dealing with the first of these questions is Coe v. Errol,[540] in which the matter at issue was the right of the town of Errol, New Hampshire, to tax certain logs on their way to points in Maine, while they lay in the river before the town or along its shore awaiting the spring freshets and consequent rise of the river. As to the logs in the river, which had come from Maine on their way to Lewiston in the same State, but had been detained at Errol by low water, the Supreme Court of New Hampshire itself ruled that the local tax did not apply, the logs being still in transit. As to the logs which had been cut in New Hampshire and lay on the shore or in tributaries of the river, both courts were again in agreement that they were still subject to local taxation, notwithstanding the intention of their owners to send them out of the State. Said Justice Bradley: "* * * goods do not cease to be part of the general mass of property in the State, subject, as such, to its jurisdiction, and to taxation in the usual way, until they have been shipped, or entered with a common carrier for transportation to another State, or have been started upon such transportation in a continuous route or journey."[541]

STATE TAXATION OF MANUFACTURING AND MINING

Under the above rule, obviously, production is not interstate commerce even though the thing produced is intended for the interstate market. Thus a Pennsylvania ad valorem tax on anthracite coal when prepared and ready for shipment was held not to be an interference with interstate commerce although applied to coal destined for a market in other States;[542] and in Oliver Iron Company v. Lord[543] an occupation tax on the mining of iron ore was upheld, although substantially all of the ore was immediately and continuously loaded on cars and shipped into other States. Said the Court: "Mining is not interstate commerce, but, * * * subject to local regulation and taxation. Its character in this regard is intrinsic, is not affected by the intended use or disposal of the product, is not controlled by contractual engagements, and persists even though the business be conducted in close connection with interstate commerce."[544] Likewise an annual privilege tax on the business of producing natural gas in the State, computed on the value of the gas produced "as shown by the gross proceeds derived from the sale thereof by the producer," was held constitutional even though most of the gas passed into interstate commerce in continuous movement from the wells.[545] And in Utah Power and Light Co. v. Pfost[546] the generation of electricity in a State was held to be distinguishable from its transmission over wires to consumers in another State, and hence taxable by the former State. Likewise, a State statute imposing a privilege tax on the production of mechanical power for sale or use did not contravene the interstate commerce clause although applied to an engine operating a compressor to increase the pressure of natural gas and thereby permit it to be transported to purchasers in other States.[547] Similarly, a tax so much per pound on shrimp taken within the three-mile belt of the coast of the taxing State was valid, since the taxable event, the taking of the shrimp, occurred before they could be said to have entered the interstate commerce stream.[548]

PRODUCTION FOR AN ESTABLISHED MARKET

But while the production of goods intended for the interstate market is taxable by the State where it takes place, their purchase for an established market in another State is interstate commerce and as such is neither regulatable nor taxable by the State of origin, provided at any rate their trans-shipment is not unduly delayed.[549] Thus, oil gathered into the pipe lines of a distributing company and intended for the most part for customers outside the State, is in interstate commerce from the moment it leaves the wells;[550] and a like result has been reached as to natural gas.[551] "The typical and actual course of events," says the Court, "marks the carriage of the greater part as commerce among the States and theoretical possibilities may be left out of account."[552]

REJECTION OF THE ORIGINAL PACKAGE CONCEPT IN INTERSTATE COMMERCE

But the question also arises as to when goods entering a State from another State become part of the mass of property of the former and hence taxable by it? In Brown v. Maryland,[553] Chief Justice Marshall, had remarked at the close of his opinion, "We suppose the principles laid down in this case, apply equally to importations from a sister State."[554] Forty-two years later, in Woodruff v. Parham,[555] an effort was made to induce the Court, in reliance on this dictum, to apply the original package doctrine against a Mobile, Alabama tax on sales at auction, so far as it reached "imports" from sister States. The Court refused the invitation; first on the ground that Marshall's statement was obiter, the point not having been involved in Brown v. Maryland; second, because usage contemporary with the Constitution and of the Constitution itself confined the term "imports" as employed in article I, section 10 to imports from abroad; third, because the tax in question was nondiscriminatory. At the same time, nevertheless, reference was made to the power of Congress to interpose at any time in exercise of its power over commerce, "in such a manner as to prevent the States from any oppressive interference with the free interchange of commodities by the citizens of one State with those of another."[556] The same result was reached a few years later in Brown v. Houston,[557] where it was held that coal transported down the Mississippi from Pennsylvania had been validly subjected by Louisiana to a general ad valorem property tax, having "come to its place of rest, for final disposal or use," and hence become "a part of the general mass of property in the State."[558] Again, however, a caveat was entered in behalf of the power of Congress to impose a different rule affording "a temporary exemption" of property transported from one State to another from taxation by the latter.[559]

INSPECTION CHARGES

Woodruff v. Parham and Brown v. Houston are still good law for the most part.[560] Nevertheless, there is one respect in which imports from sister States are treated as "imports" in the sense of the Constitution, and that is in being exempt from "unreasonable" inspection charges.[561] It is true, also, that in a series of cases involving sales of oil about 1920 the Court appeared to be contemplating reviving the original package doctrine,[562] but these holdings were presently "qualified" in a sweeping opinion by Chief Justice Taft, reviewing the cases.[563] But taxation is one thing, prohibition another. In the field of the police power, where its applicability was not so much as suggested in Brown v. Maryland, the original package doctrine has been frequently invoked by the Court against State legislation, and even today, perhaps retains a spark of life.[564]

LOCAL SALES: PEDDLERS

By the same token, local sales of goods brought into a State from another State are subject to a nondiscriminatory exercise of its taxing power. Such a tax, the Court has said, "has never been regarded as imposing a direct burden upon interstate commerce and has no greater or different effect upon that commerce than a general property tax to which all those enjoying the protection of the State may be subjected"; and this is true, even of goods immediately to be used in interstate commerce.[565] The commerce clause, therefore, does not prohibit a State from imposing special license taxes on merchants using profit sharing coupons and trading stamps although the coupons may have been inserted in retail packages by the manufacturer or shipper outside the State and are redeemable outside the State, either by such manufacturer or shipper, or by some other agency outside the State;[566] nor yet a nondiscriminatory tax upon local peddling of goods and sales thereof by peddlers even though the goods are foreign or interstate imports, since the sale occurs after foreign or interstate commerce thereof has ended.[567] And in Kehrer v. Stewart[568] it was held that a State tax upon resident managing agents of nonresident meatpacking houses did not conflict with the commerce clause, regardless of the fact that the greater portion of the business was interstate in character, the tax having been construed by the highest court of the State as applying only to the business of selling to local customers from the stock of "original packages" shipped into the State without a previous sale or contract to sell, and kept and held for sale in the ordinary course of trade. Contrariwise, a tax on sales discriminatory in its incidence against merchandise because of its origin in another State is ipso facto unconstitutional. The leading case is Welton v. Missouri,[569] decided in 1876, in which a peddler's license tax confined to the sale of goods manufactured outside the State was set aside. The doctrine of Welton v. Missouri has been reiterated many times.[570]

STOPPAGE IN TRANSIT

It also follows logically from Coe v. Errol,[571] and the cases deriving from it, that a State may impose a nondiscriminatory tax when there is a break in interstate transit, and the goods have not been restored to the current of interstate commerce. The effect of an interruption upon the continuity of an interstate movement depends upon its causes and purposes. If the delay is due to the necessities of the journey, as in the Coe case, where the logs were detained for a time within the State by low water, they are deemed "in the course of commercial transportation, and * * * clearly under the protection of the Constitution."[572] Intention thus often enters into the determination of the question whether goods from another State have come to rest sufficiently to subject them to the local taxing power. In a typical case the Court held that oil shipped from Pennsylvania and held in tanks in Memphis, Tennessee for separation, distribution and reshipment, was subject to the taxing power of the latter State.[573] The delay in transportation resulting from these proceedings on the part of the owners, the Court pointed out, was clearly designed for their own profit and convenience and was not a necessary incident to the method of transportation adopted, as had been the delay of the logs coming from Maine in Coe v. Errol. The distinction is fundamental.[574]

Applying this rule in more recent cases, the Court has upheld State taxation: on the use and storage of gasoline brought into the State by a railroad company and unloaded and stored there, to be used for its interstate trains;[575] on gasoline imported and stored by an airplane company and withdrawn to fill airplanes that use it in their interstate travel;[576] on supplies brought into the State by an interstate railroad company to be used in replacements, repairs and extensions, and installed immediately upon arrival in the taxing State;[577] on equipment brought into the State by a telephone and telegraph company for operation, maintenance, and repair of its interstate system.[578] In all these cases the Court applied the principle that "use and storage" are subject to local taxation when "there is an interval after the articles have reached the end of their interstate movement and before their consumption in interstate operation has begun."[579] On the other hand, in the absence of such an "interval," the Court declared invalid State gasoline taxes imposed per gallon of gasoline imported by interstate carriers as fuel for use in such vehicles, and used within the State as well as in their interstate travel.[580]

THE DRUMMER CASES; ROBBINS v. SHELBY COUNTY TAXING DISTRICT

But there is one situation in which goods introduced into one State from another have until recent years enjoyed a special immunity from taxation by the former, and that is when they were introduced in consequence of a contract of sale. The leading case is Robbins v. Shelby County Taxing District,[581] in which the Court, after a penetrating survey of commercial practices, ruled that "the negotiation of sales of goods"—in this instance by sample—"which are in another State, for the purpose of introducing them into the State in which the negotiation is made, is interstate commerce." In short, whereas in foreign commerce, importation is succeeded by the right to sell in the original package, in interstate commerce sale was succeeded by the right of importation, which continued until the goods reached the hands of the purchaser. The benefits of this holding were extended in a series of rulings in which it was held to apply whether solicitation of orders was or was not made with sample,[582] and to sales which were not, accurately speaking, consummated until the actual delivery of the goods, which was attended by local incidents. So, where a North Carolina agent of a Chicago firm took orders for framed pictures, which were then sent to him packed separately from the frames and then framed by him before delivery, the rule laid down in the Robbins case was held to apply throughout, with the result that North Carolina could tax or license no part of the transaction described;[583] so also as to a sewing machine ordered by a customer in North Carolina and sent to her C.O.D.;[584] so also as to brooms sent in quantity for the fulfillment of a number of orders, and subject to rejection by the purchaser if deemed by him not up to sample.[585] Said Justice Holmes in the case last referred to: "'Commerce among the States' is a practical conception not drawn from the 'witty diversities' * * * of the law of sales. * * * The brooms were specifically appropriated to specific contracts, in a practical, if not in a technical, sense. Under such circumstances it is plain that, wherever might have been the title, the transport of the brooms for the purpose of fulfilling the contracts was protected commerce."[586] Nor did it make any difference that the solicitor received his compensation in form of down payment by the purchaser.[587] Moreover, sales under a mail order business, with delivery taking place within the State to a carrier for through shipment to another State to fill orders, was held to be beyond the taxing power of the first State.[588] The fact that a concern doing a strictly interstate business had goods on hand within the State which were capable of being used in intrastate commerce, did not, the Court declared, take the business out of the protection of the commerce clause and allow the State to impose a privilege tax on such concern.

LIMITATION OF THE ROBBINS CASE

On the other hand, it was early held that the rule laid down in the Robbins case did not prevent a State from taxing a resident citizen who engaged in a general commission business, on the profits thereof, although the business consisted "for the time being, wholly or partially in negotiating sales between resident and nonresident merchants, of goods situated in another State."[589] Also, it has been held that a stamp tax on transfers of corporate stock, as applied to a sale between two nonresidents, of the stock of foreign railway corporations, was not an interference with interstate commerce.[590] Likewise, the business of taking orders on commission for the purchase and sale of grain and cotton for future delivery not necessitating interstate shipment was ruled not to be interstate commerce, and as such exempt from taxation, although deliveries were sometimes made by interstate shipment.[591] And in Banker Bros. Co. v. Pennsylvania[592] it was held that a tax upon a domestic corporation selling automobiles built by a foreign corporation under an arrangement by which the latter agreed to build for and sell to the former, for cash, at a specified price less than list price, was not a tax on interstate transactions, there being nothing which connected the ultimate buyer with the manufacturer but a warranty and the buyer's agreement to pay the list price f.o.b. factory. Similarly, in Browning v. Waycross[593] it was held that the business of erecting lightning rods within the limits of a town by the agent of a nonresident manufacturer on whose behalf such agent had solicited orders for the sale of the rods, and from whom he had received them when shipped into the State, was validly subjected to a municipal license tax. "It was not," said the Court, "within the power of the parties by the form of their contract to convert what was exclusively a local business, * * *, into an interstate commerce business * * *"[594] Also, a municipal license tax upon persons engaged in the business of buying or selling cotton for themselves was found not to impose a forbidden burden upon interstate commerce even though the cotton was purchased with a view to ultimate shipment in some other State or country.[595] Nor was a gallonage tax imposed by a State upon a distributor of liquid fuel rendered repugnant to the commerce clause by the fact that the distributor caused fuel sold to customers in the State to be shipped from another State for delivery in tank cars—"deemed original packages"—on purchaser's siding, as agreed. Said the Court: "The contracts were executory and related to unascertained goods. * * * It does not appear that when they were made appellant had any fuels of the kinds covered, or that those to be delivered were then in existence. There was no selection of goods by purchasers. Appellant was not required by the contracts to obtain the fuels at Wilmington but was free to effect performance by shipping from, any place within or without Pennsylvania."[596]

THE ROBBINS CASE TODAY

In the cases reviewed in the preceding paragraph protestants against local taxation appealed, but unavailingly, to the Robbins case. So it would seem that the generative powers of that prolific precedent had begun to wane somewhat even before the Depression, an event which rendered judicial reaction against it still more pronounced. Indeed, by the Court's decision in McGoldrick v. Berwind-White Co.,[597] in 1940, the authority of the entire line of cases descending from Robbins v. Shelby County Taxing District was seriously impaired, for the time being, while a second holding the same year seemed to reduce the significance of the Robbins case itself to that of a reassertion of the elementary rule against discrimination. "The commerce clause," Justice Reed remarked sententiously, "forbids discrimination, whether forthright or ingenious."[598]

DEPRESSION CASES: USE TAXES

With a majority of the States on the verge of bankruptcy, extensive recourse was had to sales taxes and, as an offset to these in favor of the local economy, "use" taxes on competing products coming from sister States. The basic decision sustaining the use tax, in this novel employment of it, was Henneford v. Silas Mason Co.,[599] in which was involved a State of Washington two per cent tax on the privilege of using products coming from sister States. Excepted from the tax, on the other hand, was any property the sole use of which had already been subjected to an equal or greater tax, whether under the laws of Washington or any other State. Stressing this provision in its opinion, the Court said: "Equality is the theme that runs through all the sections of the statute. * * * When the account is made up, the stranger from afar is subject to no greater burdens as a consequence of ownership than the dweller within the gates."[600] There being no actual discrimination in favor of Washington products, the tax was valid.

DEPRESSION CASES: SALES TAXES

A companion piece of the Henneford case in motivation, although it occurred three years later, was McGoldrick v. Berwind-White Coal Mining Company,[601] in which it was held that in the absence of Congressional action, a New York City general sales tax was applicable to sales of coal under contracts entered into within the municipality and calling for delivery therein. Speaking for the majority, Justice Stone declared any "distinction * * * between a tax laid on sales made, without previous contract, after the merchandise had crossed the State boundary, and sales, the contracts for which when made contemplate or require the transportation of merchandise interstate to the taxing State," to be "without the support of reason or authority";[602] and the Robbins case was held to be "narrowly limited to fixed-sum license taxes imposed on the business of soliciting order for the purchase of goods to be shipped interstate, * * *"[603] Three Justices, speaking by Chief Justice Hughes, dissented. Three companion cases decided the same day were found to follow the Berwind-White pattern,[604] while a fourth was held not to, on the ground that foreign commerce was involved.[605] For the time being Robbins and family looked to be on the way out.

END OF THE DEPRESSION CASES

Two cases, decided respectively in 1944 and 1946, signalized the end of the Depression. In McLeod v. Dilworth Co.,[606] a divided Court ruled that a sales tax could not be validly imposed by a State on sales to its residents which were consummated by acceptance of orders in, and shipment of goods from another State, in which title passed upon delivery to the carrier. Said Justice Frankfurter for the majority: "A sales tax and a use tax in many instances may bring about the same result. But they are different in conception, are assessments upon different transactions, * * * A sales tax is a tax on the freedom of purchase * * * A use tax is a tax on the enjoyment of that which was purchased. In view of the differences in the basis of these two taxes and the differences in the relation of the taxing State to them, a tax on an interstate sale like the one before us and unlike the tax on the enjoyment of the goods sold, involves an assumption of power by a State which the Commerce Clause was meant to end."[607] He also "distinguished" the Berwind-White case—just as it had "distinguished" the Robbins case—but not to the satisfaction of three of his brethren, who found the decision to mark a retreat from the Berwind-White case.[608]

The second case, Nippert v. Richmond,[609] involved a municipal ordinance imposing upon solicitors of orders for goods a license tax of fifty dollars and one-half of one per cent of the gross earnings, commissions, etc., for the preceding year in excess of $1,000. Speaking for the same majority that had decided McLeod v. Dilworth Co., Justice Rutledge found that "as the case has been made, the issue is substantially whether the long line of so-called 'drummer cases' beginning with Robbins v. Shelby County Taxing District, 120 U.S. 489, shall be adhered to in result or shall now be overruled in the light of what attorneys for the city say are recent trends requiring that outcome."[610] The tax was held void, Berwind-White being not only "distinguished" this time, but also "explained." "The drummer," said Justice Rutledge, "is a figure representative of a by-gone day," citing Wright, Hawkers and Walkers in Early America (1927). "But his modern prototype persists under more euphonious appellations. So endure the basic reasons which brought about his protection from the kind of local favoritism the facts of this case typify."[611]

A year later a Mississippi "privilege tax" laid upon each person soliciting business for a laundry not licensed in the State, was set aside directly on the authority of the Robbins case.[612] It would appear that Robbins and his numerous progeny can once more claim full constitutional status.[613]

TAXATION OF CARRIAGE OF PERSONS

Whether the carriage of persons from one State to another was a branch of interstate commerce was a question which the Court was able to side-step in Gibbons v. Ogden.[614] A quarter of a century later, however, an affirmative answer was suggested in the Passenger Cases,[615] in which a State tax on each passenger arriving on a vessel from a foreign country was set aside, though chiefly in reliance on existing treaties and acts of Congress. But similar cases arising after the Civil War were disposed of by direct recourse to the commerce clause.[616] Meantime, in 1865, the newly admitted State of Nevada, in an endeavor to prevent a threatened dissipation of its population, levied a special tax on railroad and stage companies for every passenger they carried out of the State, and in Crandall v. Nevada[617] this act was held void on the general ground that the National Government had at all times the right to require the services of its citizens at the seat of government and they the correlative right to visit the seat of government, rights which, if the Nevada tax was valid, were at the mercy of any State, the power to tax being without limit. Reference was also made to the right of the government to transport troops at all times by the most expeditious method. Two of the Justices, however, rejected this line of reasoning and held the act to be void under the commerce clause.[618] But it was not until 1885 that the Court, in deciding Gloucester Ferry Company v. Pennsylvania,[619] stated flatly that "Commerce among the States * * * includes the transportation of persons,"[620] and hence was not taxable by the States, a proposition which is still good law.[621] Four years earlier it had been held that the transmission of telegraph messages from one State to another, being interstate commerce, was something that the State of origin could not tax.[622]

State Taxation of the Interstate Commerce Privilege: Foreign Corporations

DOCTRINAL HISTORY

In the famous case of Paul v. Virginia,[623] decided in 1869, it was held that a corporation chartered by one State could enter other States only with their assent, which might "be granted upon such terms and conditions as those States may think proper to impose";[624] but along with this holding went the statement that "the power conferred upon Congress to regulate commerce includes as well commerce carried on by corporations as commerce carried on by individuals."[625] And in the State Freight Tax Case it is implied that no State can regulate or restrict the right of a "foreign" corporation—one chartered by another State—to carry on interstate commerce within its borders,[626] an implication which soon became explicit. In Leloup v. Port of Mobile,[627] decided in 1888, the Court had before it a license tax on a telegraph company which was engaged in both domestic and interstate business. The general nature of the exaction did not suffice to save it. Said the Court: "The question is squarely presented to us, * * *, whether a State, as a condition of doing business within its jurisdiction, may exact a license tax from a telegraph company, a large part of whose business is the transmission of messages from one State to another and between the United States and foreign countries, and which is invested with the powers and privileges conferred by the act of Congress passed July 24, 1866, and other acts incorporated in Title LXV of the Revised Statutes? Can a State prohibit such a company from doing such a business within its jurisdiction, unless it will pay a tax and procure a license for the privilege? If it can, it can exclude such companies, and prohibit the transaction of such business altogether. We are not prepared to say that this can be done."[628]

In Crutcher v. Kentucky[629] a like result was reached, without assistance from an act of Congress, with respect to a Kentucky statute which provided that the agent of an express company not incorporated by the laws of that State should not carry on business there without first obtaining a license from the State, and that, preliminary thereto, he must satisfy the auditor of the State that the company he represented was possessed of an actual capital of at least $150,000. The act was held to be a regulation of interstate commerce so far as applied to a corporation of another State in that business. "To carry on interstate commerce," said the Court, "is not a franchise or a privilege granted by the State; it is a right which every citizen of the United States is entitled to exercise under the Constitution and laws of the United States; and the accession of mere corporate facilities, as a matter of convenience in carrying on their business, cannot have the effect of depriving them of such right, unless Congress should see fit to interpose some contrary regulation on the subject."[630]

LICENSE TAXES

The demand for what in effect is a license is, of course, capable of assuming various guises. In Ozark Pipe Line v. Monier[631] an annual franchise tax on foreign corporations equal to one-tenth of one per cent of the par value of their capital stock and surplus employed in business in the State was found to be a privilege tax, and hence one which could not be exacted of a foreign corporation whose business in the taxing State consisted exclusively of the operation of a pipe line for transporting petroleum through the State in interstate commerce, and of activities the sole purpose of which was the furtherance of its interstate business. Likewise a Massachusetts tax based on "the corporate surplus" of a foreign corporation having only an office in the State for the transaction of interstate business was held in Alpha Portland Cement Co. v. Massachusetts to be virtually an attempt to license interstate commerce.[632] In the same category of unconstitutional taxation of the interstate commerce privilege, the Court has also included the following: a State "franchise" tax on a foreign corporation, whose sole business in the State consisted in landing, storing and selling in the original package goods imported by it from abroad, the tax being imposed annually on the doing of such business and measured by the value of the goods on hand;[633] a State privilege or occupation tax on every corporation engaged in the business of operating and maintaining telephone lines and furnishing telephone service in the State, of so much for each telephonic instrument controlled and operated by it, as applied to a company furnishing both interstate and intrastate service, and employing the same telephones, wires, etc., in both as integrated parts of its system;[634] a State occupation tax measured by the entire gross receipts of the business of a radio broadcasting station, licensed by the Federal Communications Commission, and engaged in broadcasting advertising "programs" for customers for hire to listeners within and beyond the State, since it did not "appear that any of the taxed income ... [was] allocable to interstate commerce";[635] a State occupation tax on the business of loading and unloading vessels engaged in interstate and foreign commerce;[636] an Indiana income tax imposed on the gross receipts from commerce inasmuch as the tax reached indiscriminately and without apportionment the gross income from both interstate commerce and intrastate activities;[637] an Arkansas statute making entry into the State of motor vehicles carrying more than twenty gallons of gasoline conditional on the payment of an excise on the excess.[638]

DOCTRINE OF WESTERN UNION TELEGRAPH v. KANSAS EX REL. COLEMAN

One of the most striking concessions ever made by the Court to the interstate commercial interest at the expense of the State's taxing power was that which appeared originally in 1910, in Western Union Telegraph. Co. v. Kansas ex rel. Coleman,[639] which involved a percentage tax upon the total capitalization of all foreign corporations doing or seeking to do a local business in the State. The Court pronounced the tax, as to the Western Union, a burden upon the company's interstate business and upon its property located and used outside the State, and hence void under both the commerce clause and the due process of law clause of the Fourteenth Amendment. The decision was substantially aided by the fact that the company had been doing a general telegraphic business within the State for more than fifty years without having been subjected to such an exaction.[640]

SPREAD OF THE DOCTRINE

The doctrine of the case, however, soon cast off these initial limitations. In Looney v. Crane Company[641] a similar tax by the State of Texas was disallowed as to an Illinois corporation, engaged in its home State in the manufacture of hardware, but maintaining in Texas depots and warehouses from which orders were filled and sales made, likewise, in International Paper Company v. Massachusetts,[642] it was clearly stated that "the immunity of interstate commerce from State taxation" is not confined to what is done by carriers in such commerce, but "is universal and covers every class of ... [interstate] commerce, including that conducted by merchants and trading companies." On the same occasion the general proposition was laid down that "the power of a State to regulate the transaction of a local business within its borders by a foreign corporation, ... is not unrestricted or absolute, but must be exerted in subordination to the limitations which the Constitution places on State action."[643]

STATUS OF THE DOCTRINE TODAY

The precise standing of this doctrine is, nevertheless, seriously clouded by certain more recent holdings. In Sprout v. South Bend,[644] decided in 1928, the doctrine was still applied, to disallow a license tax on concerns operating a bus interstate. Pointing to the fact that the ordinance made no distinction between busses engaged exclusively interstate and those engaged intrastate or both interstate and intrastate, the Court said: "In order that the fee or tax shall be valid, it must appear that it is imposed solely on account of the intrastate business; that the amount exacted is not increased because of the interstate business done; that one engaged exclusively in interstate commerce would not be subject to the imposition; and that the person taxed could discontinue the intrastate business without withdrawing also from the interstate business."[645] Likewise, in Cooney v. Mountain States Telephone and Telegraph Co., the Court asserted that to sustain a State occupation tax on one whose business is both interstate and intrastate, "it must appear * * *, and that the one [who is] taxed could discontinue the intrastate business without [also] withdrawing from the interstate business."[646] A year later, nevertheless, Justice Brandeis, speaking for the Court in Pacific Telephone and Telegraph Co. v. Tax Commission,[647] asserted flatly: "No decision of this Court lends support to the proposition that an occupation tax upon local business, otherwise valid, must be held void merely because the local and interstate branches are for some reason inseparable."[648] An occupation tax, like other taxes and expenses, lessens the benefit derived by interstate commerce from the joint operation with it of the intrastate business of the carrier; but it is not an undue burden on interstate commerce where, as in this case, the advantage to the carrier, and to the interstate commerce, of continuing the intrastate business is greatly in excess of the tax. And subsequent holdings in cases involving foreign corporations doing a mixed business, comprising both interstate and intrastate elements, have tended on the whole to restore the rule stated in Paul v. Virginia[649] shortly after the Civil War, that the Constitution does not confer upon a foreign corporation the right to engage in local business in a State without its assent, which it may give on such terms as it chooses.[650]

State Taxation of Property Engaged in, and of the Proceeds From, Interstate Commerce

GENERAL ISSUE

In this area of Constitutional Law the principle asserted in the State Freight Tax Case,[651] that a State may not tax interstate commerce, is confronted with the principle that a State may tax all purely domestic business within its borders and all property "within its jurisdiction." Inasmuch as most large concerns prosecute both an interstate and a domestic business, while the instrumentalities of interstate commerce and the pecuniary returns from such commerce are ordinarily property within the jurisdiction of some State or other, the task before the Court in drawing the line between the immunity claimed by interstate business on the one hand and the prerogatives claimed by local power on the other has at times involved it in self-contradiction, as successive developments have brought into prominence novel aspects of its complex problem or have altered the perspective in which the interests competing for its protection have appeared. In this field words of the late Justice Rutledge, spoken in 1946, are especially applicable: "For cleanly as the commerce clause has worked affirmatively on the whole, its implied negative operation on State power has been uneven, at times highly variable. * * * Into what is thus left open for inference to fill, divergent ideas of meaning may be read much more readily than into what has been made explicit by affirmation. That possibility is broadened immeasurably when not logic alone, but large choices of policy, affected in this instance by evolving experience of federalism, control in giving content to the implied negation."[652]

DEVELOPMENT OF THE APPORTIONMENT RULE

At the outset the Court appears to have thought that it could solve all difficulties by the simple device of falling back on Marshall's opinion in Brown v. Maryland;[653] and on the same day that it set aside Pennsylvania's freight tax by appeal to that transcendent precedent, it sustained, by reference to the same authority, a Pennsylvania tax on the gross receipts of all railroads chartered by it, the theory being that such receipts had, by tax time, become "part of the mass of property of the State."[654] This precedent stood fourteen years, being at last superseded by a ruling in which substantially the same tax was held void as to a Pennsylvania chartered steamship company.[655] A year later the Court sustained Massachusetts in levying a tax on Western Union, a New York corporation, on account of property owned and used by it in the State, taking as the basis of the assessment such proportion of the value of its capital stock as the length of its lines within the State bore to their entire length throughout the country.[656] The tax was characterized by the Court as an attempt by Massachusetts "to ascertain the just amount which any corporation engaged in business within its limits shall pay as a contribution to the support of its government upon the amount and value of the capital so employed by it therein."[657] And drawing on certain decisions in which it had sought to limit the principle of tax exemption as applied in the case of railroads chartered by the United States, it expressed concern that "the necessary powers of the States" should not be destroyed or "their efficient exercise" be prevented.[658] Three years later Pennsylvania, still in quest of revenue, was sustained in applying the Massachusetts idea to Pullman's Palace Car Company, a "foreign" corporation.[659] Pointing to the fact that the company had at all times substantially the same number of cars within the State and continuously and constantly used there a portion of its property, the Court commended the State for taking "as a basis of assessment such proportion of the capital stock of the company as the number of miles over which it ran cars within the State bore to the whole number of miles, in that and other States, * * *" This, said the Court, was "a just and equitable method of assessment;" one which, "if it were adopted by all the States through which these cars ran, the company would be assessed upon the whole value of its capital stock, and no more."[660]

THE UNIT RULE

And pursuing the same course of thought, the Court, in Adams Express Company v. Ohio,[661] decided in 1897, sustained that State in taxing property worth less than $70,000.00 at a valuation of more than half a million, on the ground that the latter figure did not exceed, in relation to the total capital value of the company, the proportion borne by the railway mileage which the company covered in Ohio to the total mileage which it covered in all States. To the objection that "the intangible values" reached by the tax were derived from interstate commerce, the Court replied with the "cardinal rule * * * that whatever property is worth for purposes of income and sale it is also worth for purposes of taxation,"[662] which obviously does not meet the issue. What the case indubitably establishes is that a State may tax property within its limits "as part of a going concern" and hence "at its value as it is in its organic relations," although those relations constitute interstate commerce.[663] In short, values created by interstate commerce are taxed.

Thus emerged the concept of an "apportioned" tax, or as it is called when applied to the problem of property valuation, the "unit rule," which till 1938 afforded the Court its chief reliance in the field of Constitutional Law now under review. The theory underlying the concept appears to be that it is always possible for a State to devise a formula whereby it may assign to the property employed in interstate commerce within its limits, or to the proceeds from such commerce, a value which it may tax or by which it may "measure" a tax, without unconstitutionally burdening or interfering with interstate commerce, while at the same time exacting from it a fair return for the protection which the State gives it. The question in each case is, of course, whether the State has guessed right.

APPORTIONED PROPERTY TAXES

In reliance on the apportionment concept the Court has at various times sustained, in the case of a sleeping car company, as we have seen, a valuation based on the ratio of the miles of track over which the company runs within the State to the whole track mileage over which it runs;[664] in the case of a railroad company, a valuation based on the ratio of its mileage within the State to its total mileage;[665] in the case of a telegraph company, a valuation based upon the ratio of its length of line within the State to its total length;[666] in the case of an express company, as we have just seen, a valuation based upon the ratio of miles covered by it in the State to the mileage covered by it in all States.[667] Also, a tax has been upheld as to a railroad line whose principal business was hauling ore from mines in the taxing State to terminal docks outside the State, where the line and the docks were treated by the railway as a unit, the charge for the dock service being absorbed in the charge per ton transported; and where the evidence did not show that the mileage value of the part of the line outside of the taxing State, with the docks included, was greater than the mileage value of part within it.[668] Nor does the commerce clause preclude the assessment of an interstate railway within a State by taking such part of the value of the railroad's entire system, less the value of its localized property, such as terminal buildings, shops and nonoperating real estate, as is represented by the ratio which the railroad's mileage within the State bears to its total mileage.[669] To the objection that the mileage formula was inapplicable in this instance because of the disparity of the revenue-producing capacity between the lines in and out of the State, the Court answered that mathematical exactitude in making an apportionment had never been a constitutional requirement. "Wherever," it explained, "the State's taxing authorities have been held to have intruded upon the protected domain of interstate commerce in their use of a mileage formula, the special circumstances of the particular situation, in the view which this Court took of them, precluded a defensible utilization of the mileage basis."[670] The principle of apportionment is, moreover, applicable to the intangible property of a company engaged in both interstate and local commerce, as well as to its tangible property.[671]

APPORTIONED GROSS RECEIPTS TAXES

The first State to attempt to employ the apportionment device in order to tax the gross receipts of companies engaged in interstate commerce was Maine, in connection with a so-called "franchise tax," which was levied on such proportion of the revenues of railroads operating in the State as their mileage there bore to their total mileage. In Maine v. Grand Trunk Railway Company,[672] a sharply divided Court upheld the tax on the basis of its designation, giving scant attention to its apportionment feature. Said Justice Field for the majority: "The privilege of exercising the franchises of a corporation within a State is generally one of value, and often of great value, and the subject of earnest contention. It is natural, therefore, that the corporation should be made to bear some proportion of the burdens of government. As the granting of the privilege rests entirely in the discretion of the State, whether the corporation be of domestic or foreign origin, it may be conferred upon such conditions, pecuniary or otherwise, as the State in its judgment may deem most conducive to its interests or policy."[673] Four Justices, speaking by Justice Bradley, protested forcefully that the decision directly contradicted a whole series of decisions holding that the States are without power to tax interstate commerce;[674] and seventeen years later another sharply divided Court endorsed this contention when it overturned a Texas gross receipts tax drawn on the lines of the earlier Maine statute.[675] The Maine tax, however, the later Court suggested, had been in the nature of a commutation tax in lieu of all taxes, which the Texas tax was not.[676]
