CHAPTER XI.
Report of the Committee of Detail, Continued.—The Remaining Powers of Congress.—Restraints Upon Congress and Upon the States.
In the last preceding chapter, the reader has traced the origin of the revenue and commercial powers, and of certain restrictions applied to them in the progress of those great compacts, by means of which they became incorporated into the Constitution. We have now to examine some other qualifications which were annexed to those powers after the first draft of the instrument had been prepared and reported by the committee of detail.
That committee had presented a naked power to lay and collect taxes, duties, imposts, and excises,[232] with a certain restriction as to the taxation of exports, the final disposition of which has been already described; but they had designated no particular objects to which the revenues thus derived were to be applied. The general clause embracing the revenue power was affirmed unanimously by the Convention, on the 16th of August, leaving the exception of exports for future action. At a subsequent period we find the words, "to pay the debts and provide for the common defence and general welfare of the United States," added to the clause which empowers Congress to levy taxes and duties; and it is a somewhat important inquiry, how and with what purpose they were placed there.
While the powers proposed by the committee of detail were under consideration, Mr. Charles Pinckney introduced several topics designed to supply omissions in their report, which were thereupon referred to that committee. The purpose of one of his suggestions was to provide, on the one hand, that funds appropriated for the payment of public creditors should not, during the time of such appropriation, be diverted to any other purpose; and, on the other hand, that Congress should be restrained from establishing perpetual revenues. Another of his suggestions contemplated a power to secure the payment of the public debt, and still another to prevent a violation of the public faith when once pledged to any public creditor.[233] Immediately after this reference, Mr. Rutledge moved for what was called a grand committee,[234] to consider the expediency of an assumption by the United States of the State debts; and after some discussion of the subject, such a committee was raised, and Mr. Rutledge's motion was referred to them, together with a proposition introduced by Mr. Mason for restraining grants of perpetual revenue.[235] Thus it appears that the principal subject involved in the latter reference was the propriety of inserting in the Constitution a specific power to make special appropriations for the payment of debts of the United States and of the several States, incurred during the late war for the common defence and general welfare; and not to make a declaration of the general purposes for which revenues were to be raised. Both committees, however, seemed to have been charged with the consideration of some restraint on the revenue power, with a view to prevent perpetual taxes of any kind. The grand committee reported first, presenting the following special provision:—"The legislature of the United States shall have power to fulfil the engagements which have been entered into by Congress, and to discharge, as well the debts of the United States, as the debts incurred by the several States during the late war for the common defence and general welfare."[236] On the following day, the committee of detail presented a report, recommending that at the end of the clause already adopted, which contained the grant of the revenue power, the following words should be added: "for payment of the debts and necessary expenses of the United States; provided that no law for raising any branch of revenue, except what may be specially appropriated for the payment of interest on debts or loans, shall continue in force for more than —— years."[237]
Two distinct propositions were thus before the Convention. One of them contemplated a qualification of the revenue power, the other did not. One was to give authority to Congress to pay the revolutionary debt, both of the United States and of the States, and to fulfil all the engagements of the Confederation; the other was to declare that revenues were to be raised and taxes levied for the purpose of paying the debts and necessary expenses of the United States, limiting all revenue laws, excepting those which were to appropriate specific funds to the payment of interest on debts or loans, to a term of years. When these propositions came to be acted upon, that reported by the grand committee was modified into the declaration that "all debts contracted and engagements entered into, by or under the authority of Congress, shall be as valid against the United States, under this Constitution, as under the Confederation." The State debts were thus left out; the declaration was prefixed, as an amendment, to the clause which granted the revenue power, and was thus obviously no qualification of that power.[238]
But it was thought by Mr. Sherman, that the clause for laying taxes and duties ought to have connected with it an express provision for the payment of the old debts; and he accordingly moved to add to that clause the words, "for the payment of said debts, and for the defraying the expenses that shall be incurred for the common defence and general welfare." This was regarded by the Convention as unnecessary, and was therefore not adopted.[239] But the provision reported by the committee of detail, which was intended as a qualification of the revenue power, by declaring the objects for which taxes and duties were to be levied, had not yet been acted upon, and on the 31st of August, this, with all other matters not disposed of, was referred to a new grand committee, who, on the 4th of September, introduced an amendment to the revenue clause, which made it read as follows:—"The legislature shall have power to lay and collect taxes, duties, imposts, and excises, to pay the debts, and provide for the common defence and general welfare of the United States." This amendment was unanimously adopted;[240] and when the Constitution was revised, at the close of the proceedings, the declaration which made the debts and engagements of the Confederation obligatory upon the new Congress, was separated from the context of the revenue clause, and placed by itself in the sixth article.
There is one other restraint upon the revenue, as well as upon the commercial power, the history of which now demands our inquiries. But in order to understand it correctly, it will be necessary for the reader to recur to the position in which the revenue and commercial powers were left by the sectional compromises described in the last chapter. The struggle between the Northern and the Southern States concerning the limitations of those powers turned, as we have seen, on certain restrictions desired by the latter. They wished to have exports excepted out of the revenue power; they wished to have a vote of two thirds made necessary to the passage of any commercial regulation; and three of them wished to have the slave-trade excepted from both the revenue and the commercial powers. We have seen that the result of the sectional compromises was to leave the commercial and revenue powers unlimited, excepting by the saving in relation to the slave-trade; that they left the revenue power unlimited, excepting by the restriction concerning exports and a capitation tax; and that the commercial power was to be exercised, like other legislative powers, by a majority in Congress. General commercial and revenue powers, then, without other restrictions than these, would enable Congress to collect their revenues where they should see fit, without obliging them to adopt the old ports of entry of the States, or to consider the place where a cargo was to be unladen. They might have custom-houses in only one place in each State, or in only such States as they might choose to select, and might thus compel vessels bound from or to all the other States to clear or enter at those places. But, on the other hand, a constitutional provision which would require them to establish custom-houses at the old ports of entry of the States, without leaving them at liberty to establish other ports of entry, or to compel vessels to receive on board revenue officers before they had reached their ports of destination, would create opportunities and facilities for smuggling.
It appears that the people of Maryland felt some apprehension that an unrestricted power to make commercial and fiscal regulations might result in compelling vessels bound to or from Baltimore to enter or clear at Norfolk, or some other port in Virginia. The delegates of Maryland accordingly introduced a proposition, which embraced two ideas; first, that Congress shall not oblige vessels, domestic or foreign, to enter or pay duties or imposts in any other State than in that to which they may be bound, or to clear from any other State than that in which their cargoes may be laden; secondly, that Congress shall not induce vessels to enter or clear in one State in preference to another, by any privileges or immunities.[241] This proposition became the basis of that clause of the Constitution, which declares that "no preference shall be given by any regulation of commerce or revenue to the ports of one State over those of another; nor shall vessels bound to, or from, one State, be obliged to enter, clear, or pay duties in another."[242]
It was while this subject of the equal operation of the commercial and revenue powers upon the different States was under consideration, that the further provision was devised and incorporated into the Constitution, which requires all duties, imposts, and excises to be uniform throughout the United States. This clause, in the final revision of the instrument, was annexed to the power of taxation.[243]
The commercial power, besides being subjected to the restrictions which have been thus described, was extended to a subject not embraced in it by the report of the committee of detail. They had included in it "commerce with foreign nations, and among the several States";—meaning, by the former term, not to include the Indian tribes upon this continent, but all other communities, civilized and barbarian, foreign to the people of the United States. By the system which had always prevailed in the relations of Europeans and their descendants with the Indians of America, those tribes had constantly been regarded as distinct and independent political communities, retaining their original rights, and among them the undisputed possession of the soil; subject to the exclusive right of the European nation making the first discovery of their territory to purchase it. This principle, incorporated into the public law of Europe at the time of the discovery and settlement of the New World, and practised by general consent of the nations of Europe, was the basis of all the relations maintained with the Indian tribes by the imperial government, in the time of our colonial state, by our Revolutionary Congress, and by the United States under the Confederation. It recognized the Indian tribes as nations, but as nations peculiarly situated, inasmuch as their intercourse and their power to dispose of their landed possessions were restricted to the first discoverers of their territory. This peculiar condition drew after it two consequences;—first, that, as they were distinct nations, they could not be treated as part of the subjects of any one of the States, or of the United States; and secondly, that, as their intercourse and trade were subjected to restraint, that restraint would be most appropriately exercised by the federal power. So general was the acquiescence in these necessities imposed by the principle of public law which defined the condition of the Indian tribes, that during the whole of the thirteen years which elapsed from the commencement of the Revolution to the adoption of the Constitution, the regulation of intercourse with those tribes was left to the federal authority. It was tacitly assumed by the Revolutionary Congress, and it was expressly conferred by the Articles of Confederation.
The provision of the Confederation on this subject gave to the United States the exclusive right and power "of regulating the trade and managing all affairs with the Indians not members of any of the States, provided that the legislative right of any State within its own limits be not infringed or violated." The exception of such Indians as were members of any State, referred to those broken members of tribes who had lost their nationality, and had become absorbed as individuals into the political community of the whites. With all other Indians, remaining as distinct and self-governing communities, trade and intercourse were subject to the regulation of Congress; while at the same time each State retained to itself the regulation of its commerce with all other nations. The broad distinction thus early established, and thus perpetuated in the Confederation, between commerce with the Indian tribes, and commerce with "foreign nations," explains the origin and introduction of a special provision for the former, as distinguished from the latter, in the Constitution of the United States.
For although there might have been some reason to contend that commerce with "foreign nations"—if the grant of the commercial power had not expressly embraced the Indian tribes—would have extended to those tribes, as nations foreign to the United States, yet the entire history of the country, and the peculiarity of the intercourse needful for their security, made it eminently expedient that there should be a distinct recognition of the Indian communities, in order that the power of Congress to regulate all commerce with them might not only be as ample as that relating to foreign nations, but might stand upon a distinct assertion of their condition as tribes. Accordingly, Mr. Madison introduced the separate proposition "to regulate affairs with the Indians, as well within as without the limits of the United States";[244] and the committee to whom it was referred gave effect to it, by adding the words, "and with the Indian tribes," to the end of the clause containing the grant of the commercial power.[245]
The remaining powers of Congress may be considered in the order in which they were acted upon by the Convention. The powers to establish a uniform rule of naturalization, to coin money and regulate the value thereof and of foreign coin, and fix the standard of weights and measures, were adopted without discussion and with entire unanimity, as they had been proposed in the draft prepared by the committee of detail. The power to establish post-offices was extended to embrace post-roads.[246]
These were succeeded by the subject of borrowing money and emitting bills on the credit of the United States; a power that was proposed to be given by the committee of detail, while they at the same time proposed to restrain the States from emitting bills of credit. I have not been able to discover upon what ground it was supposed to be proper or expedient to confer a power of emitting bills of credit on the United States, and to prohibit the States from doing the same thing. That the same thing was in contemplation in the two provisions reported by the committee, sufficiently appears from the debates and from the history of the times. The object of the prohibition on the States was to prevent the issue and circulation of paper money; the object of the proposed grant of power to the United States was to enable the government to employ a paper currency, when it should have occasion to do so. But the records of the discussions that have come down to us do not disclose the reasons which may have led to the supposition that a paper currency could be used by the United States with any more propriety or safety than by a State. One of the principal causes which had led to the experiment of making a national government with power to prevent such abuses, had been the frauds and injustice perpetrated by the States in their issues of paper money; and there was at this very time a loud and general outcry against the conduct of the people of Rhode Island, who had kept themselves aloof from the national Convention, for the express purpose, among others, of retaining to themselves the power to issue such a currency.
It is possible that the phrase "emit bills on the credit of the United States" might have been left in the Constitution, without any other danger than the hazards of a doubtful construction, which would have confined its meaning to the issuing of certificates of debt under the power to "borrow money." But this was not the sense in which the term "bills of credit" was generally received throughout the country, nor the sense intended to be given to it in the clause which contained the prohibition on the States. The well-understood meaning of the term had reference to paper issues, intended to circulate as currency, and bearing the public promise to pay a sum of money at a future time, whether made or not made a legal tender in payment of debts. It would have been of no avail, therefore, to have added a prohibition against making such bills a legal tender. If a power to issue them should once be seen in the Constitution, or should be suspected by the people to be there, wrapt in the power of borrowing money, the instrument would array against itself a formidable and probably a fatal opposition. It was deemed wiser, therefore, even if unforeseen emergencies might in some cases make the exercise of such a power useful, to withhold it altogether. It was accordingly stricken out, by a vote of nine States against two, and the authority of Congress was thus confined to borrowing money on the credit of the United States, which appears to have been intended to include the issuing of government notes not transferable as currency.[247]
The clauses which authorize Congress to constitute tribunals inferior to the Supreme Court,[248] and to make rules as to captures on land and water,[249]—the latter comprehending the grant of the entire prize jurisdiction,—were assented to without discussion.[250] Then came the consideration of the criminal jurisdiction in admiralty, and that over offences against the law of nations. The committee of detail had authorized Congress "to declare the law and punishment of piracies and felonies committed on the high seas, ... and of offences against the law of nations." The expression to "declare the law," &c. was changed to the words "define and punish," for the following reason. Piracy is an offence defined by the law of nations, and also by the common law of England. But in those codes a single crime only is designated by that term.[251] It was necessary that Congress should have the power to declare whether this definition was to be adopted, and also to determine whether any other crimes should constitute piracy. In the same way, the term "felony" has a particular meaning in the common law, and it had in the laws of the different States of the Union a somewhat various meaning. It was necessary that Congress should have the power to adopt any definition of this term, and also to determine what other crimes should be deemed felonies. So also there were various offences known to the law of nations, and generally regarded as such by civilized States. But before Congress could have power to punish for any of those offences, it would be necessary that they, as the legislative organ of the nation, should determine and make known what acts were to be regarded as offences against the law of nations; and that the power to do this should include both the power to adopt from the code of public law offences already defined by that code, and to extend the definition to other acts. The term "declare" was therefore adopted expressly with a view to the ascertaining and creating of offences, which were to be treated as piracies and felonies committed on the high seas, and as offences against the law of nations.[252]
The same necessity for an authority to prescribe a previous definition of the crime of counterfeiting the securities and current coin of the United States would seem to have been felt; and it was probably intended to be given by the terms "to provide for the punishment of" such counterfeiting.[253]
The power to "declare" war had been reported by the committee as a power to "make" war. There was a very general acquiescence in the propriety of vesting the war power in the legislature rather than the executive; but the former expression was substituted in place of the latter, in order, as it would seem, to signify that the legislature alone were to determine formally the state of war, but that the executive might be able to repel sudden attacks.[254] The clause which enables Congress to grant "letters of marque and reprisal" was added to the war power, at a subsequent period, on the recommendation of a committee to whom were referred sundry propositions introduced by Charles Pinckney, of which this was one.[255]
In addition to the war power, which would seem to involve of itself the authority to raise all the necessary forces required by the exigencies of a war, the committee of detail had given the separate power "to raise armies," which the Convention enlarged by adding the term to "support."[256] This embraced standing armies in time of peace, and, as the clause thus amended would obviously allow, such armies might be enlarged to any extent and continued for any time. The nature of the government, and the liberties and the very prejudices of the people, required that some check should be introduced, to prevent an abuse of this power. A limitation of the number of troops that Congress might keep up in time of peace was proposed, but it was rejected by all the States as inexpedient and impracticable.[257] Another check, capable of being adapted to the proper exercise of the power itself, was to be found in an idea suggested by Mr. Mason, of preventing a perpetual revenue.[258] The application of this principle to the power of raising and supporting armies would furnish a salutary limitation, by requiring the appropriations for this purpose to pass frequently under the review of the representatives of the people, without embarrassing the exercise of the power itself. Accordingly, the clause now in the Constitution, which restricts the appropriation of money to the support of the army to a term not longer than two years, was added to the power of raising and supporting armies.[259]
Authority "to provide and maintain a navy" was unanimously agreed as the most convenient definition of the power, and to this was added, from the Articles of Confederation, the power "to make rules for the government and regulation of the land and naval forces."[260]
The next subject which required consideration was the power of the general government over the militia of the States. There were few subjects dealt with by the framers of the Constitution exceeding this in magnitude, in importance, and delicacy. It involved not only the relations of the general government to the States and the people of the States, but the question whether and how far the whole effective force of the nation could be employed for national purposes and directed to the accomplishment of objects of national concern. The mode in which this question should be settled would determine, in a great degree, and for all time, whether the national power was to depend, for the discharge of its various duties in peace and in war, upon standing armies, or whether it could also employ and rely upon that great reservation of force that exists in all countries accustomed to enroll and train their private citizens to the use of arms.
The American Revolution had displayed nothing more conspicuously than the fact, that, while the militia of the States were in general neither deficient in personal courage, nor incapable of being made soldiers, they were inefficient and unreliable as troops. One of the principal reasons for this was, that, when called into the field in the service of the federal power, the different corps of the several States looked up to their own local government as their sovereign; and being amenable to no law but that of their own State, they were frequently indisposed to recognize any other authority. But a far more powerful cause of their inefficiency lay in the fact that they were not disciplined or organized or armed upon any uniform system. A regiment of militia drawn from New Hampshire was a very different body from one drawn from New York, or Pennsylvania, or New Jersey, or South Carolina. The consequence was, that when these different forces were brought to act together, there were often found in the same campaign, and sometimes in the same engagement, portions of them in a very respectable state of discipline and equipment, and others in no state of discipline or equipment at all.
The necessity, therefore, for a uniform system of disciplining and arming the militia was a thing well ascertained and understood, at the time of the formation of the Constitution. But the control of this whole subject was a part of the sovereignty of each State, not likely to be surrendered without great jealousy and distrust; and one of the most delicate of the tasks imposed upon the Convention was that of determining how far and for what purposes the people of the several States should be asked to confer upon the general government this very important part of their political sovereignty. One thing, however, was clear;—that, if the general government was to be charged with the duty of undertaking the common defence against an external enemy, or of suppressing insurrection, or of protecting the republican character of the State constitutions, it must either maintain at all times a regular army suitable for any such emergency, or it must have some power to employ the militia. The latter, when compared with the resource of standing armies, is, as was said of the institution of chivalry, "the cheap defence of nations"; and although no nation has found, or will be likely to find, it sufficient, without the maintenance of some regular troops, the nature of the liberties inherent in the construction of the American governments, and the whole current of the feelings of the American people, would lead them to the adoption of a policy that might restrain, rather than encourage, the growth of a permanent army. So far, therefore, it seemed manifest, from the duties which were to be imposed on the government of the Union, that it must have a power to employ the militia of the States; and this would of necessity draw after it, if it was to be capable of a beneficial exercise, the power to regulate, to some extent, their organization, armament, and discipline.
But the first draft of the Constitution, prepared by the committee of detail, contained no express power on this subject, excepting "to call forth the aid of the militia in order to execute the laws of the Union, enforce treaties, suppress insurrections, and repel invasions."[261] Possibly it might have been contended, after the Constitution had gone into operation, that the general power to make all laws necessary and proper for the execution of the powers specially enumerated, would enable Congress to prescribe regulations of the force which they were authorized to employ, since the authority to employ would seem to involve the right to have the force kept in a fit state to be employed. But this would have been a remote implication of power, too hazardous to be trusted; and it at once occurred to one of the wisest and most sagacious of the statesmen composing the Convention, who, though he never signed the Constitution, exercised a great and salutary influence in its preparation,—Mr. Mason of Virginia,—that an express and unequivocal power of regulating the militia must be conferred. He stated the obvious truth, that, if the disciplining of the militia were left in the hands of the States, they never would concur in any one system; and as it might be difficult to persuade them to give up their power over the whole, he was at first disposed to adopt the plan of placing a part of the militia under the control of the general government, as a select force.[262] But he, as well as others, became satisfied that this plan would not produce a uniformity of discipline throughout the entire mass of the militia. The question, therefore, resolved itself practically into this,—what should be the nature and extent of the control to be given to the general government, assuming that its control was to be applicable to the entire militia of the several States. This important question, involved in several distinct propositions, was referred to a grand committee of the States.[263] It was by them that the plan was digested and arranged by which Congress now has the power to provide for organizing, arming, and disciplining the militia, and for governing such part of them as may be employed in the service of the United States, reserving to the States the appointment of the officers, and the authority of training the militia according to the discipline prescribed by Congress;[264]—a provision that was adopted by a large majority of the States. The clause reported by the committee of detail was also adopted, by which Congress is enabled to provide for calling forth the militia to execute the laws of the Union, suppress insurrections, and repel invasions.[265]
The next subject in the order of the report made by the committee of detail was that general clause now found at the close of the enumeration of the express powers of Congress, which authorizes them "to make all laws which may be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by this Constitution in the government of the United States, or in any department or officer thereof."[266] Nothing occurred in the proceedings on this provision which throws any particular light upon its meaning, excepting a proposition to include in it, expressly, the power to "establish all offices" necessary to execute the powers of the Constitution; an addition which was not made, because it was considered to be already implied in the terms of the clause.[267]
The subjects of patents for useful inventions and of copyrights of authors appear to have been brought forward by Mr. Charles Pinckney. They gave rise to no discussion in the Convention, but were considered in a grand committee, with other matters, and there is no account of the views which they took of this interesting branch of the powers of Congress. We know, however, historically, that these were powers not only possessed by all the States, but exercised by some of them, before the Constitution of the United States was formed. Some of the States had general copyright laws, not unlike those which have since been enacted by Congress;[268] but patents for useful inventions were granted by special acts of legislation in each case. When the power to legislate on these subjects was surrendered by the States to the general government, it was surrendered as a power to legislate for the purpose of securing a natural right to the fruits of mental labor. This was the view of it taken in the previous legislation of the States, by which the power conferred upon Congress must of course, to a large extent, be construed.
Such are the legislative powers of Congress, which are to be exercised within the States themselves;—and it is at once obvious, that they constitute a government of limited authority. The question arises, then, whether that authority is anywhere full and complete, embracing all the powers of government and extending to all the objects of which it can take cognizance. It has already been seen, that, when provision was made for the future acquisition of a seat of government, exclusive legislation over the district that might be acquired for that purpose was conferred upon Congress.[269] In the same clause, the like authority was given over all places that might be purchased, with the consent of any State legislature, for the erection of forts, magazines, arsenals, dock-yards, and other needful buildings.[270] All the other places to which the authority of the United States can extend are included under the term "territories," which are out of the limits and jurisdiction of any State. As this is a subject which is intimately connected with the power to admit new States into the Union, we are now to consider the origin and history of the authority given to Congress for that purpose.
In examining the powers of Congress contained in the first article of the Constitution, the reader will not find any power to admit new States into the Union; and while he will find there the full legislative authority to govern the District of Columbia and certain other places ceded to the United States for particular purposes, of which I have already spoken, he will find no such authority there conferred in relation to the territory which had become the property of the United States by the cession of certain of the States before and after the adoption of the Articles of Confederation. If this power of legislation exists as to the territories, it is to be looked for in another connection; and although it is not the special province of this work to discuss questions of construction, it is proper here to state the history of those portions of the Constitution which relate to this branch of the authority of Congress.
In the first volume of this work, I have given an account of the origin of the Northwestern Territory, of its relations to the Union, and of the mode in which the federal Congress had dealt with it down to the time when the national Convention was assembled.[271] From the sources there referred to, and from others to which reference will now be made, it may be convenient to recapitulate what had been done or attempted by the Congress of the Confederation.
It appears that during the preparation of the Articles of Confederation an effort was made to include in them a grant of express power to the United States in Congress to ascertain and fix the western boundaries of the existing States, and to lay out the territory beyond the boundaries that were to be thus ascertained into new States. This effort totally failed. It was founded upon the idea that the land beyond the rightful boundaries of the old States was already, or would by the proposed grant of power to ascertain those boundaries become, the common property of the Union. But the States, which then claimed an uncertain extension westward from their actual settlements, were not prepared for such an admission, or such a grant; and accordingly the Articles of Confederation, which were issued in 1777 and took effect in 1781, contained no express power to deal with landed property of the United States, and no provision which could safely be construed into a power to form and admit new States out of then unoccupied lands anywhere upon the continent. Still, the Articles were successively ratified by some of the States, and finally became established, in the express contemplation that the United States should be made the proprietor of such lands, by the cession of the States which claimed to hold them. In order to procure such cessions, as the means of inducing a unanimous accession to the confederacy, the Congress in 1780 passed a resolve, in which they promised to dispose of the lands for the common benefit of the United States, to settle and form them into distinct republican States, and to admit such States into the Union on an equal footing with its present members.[272] The great cession by Virginia, made in 1784, was immediately followed by another resolve, for the regulation of the territory thus acquired.[273]
This resolve, as originally reported by Mr. Jefferson, embraced a plan for the organization of temporary governments in certain States which it undertook to describe and lay out in the Western territory, and for the admission of those States into the Union. In one particular, also, it undertook, as it was first reported, to regulate the personal rights or relations of the settlers, by providing that, after the year 1800, slavery, or involuntary servitude except for crime, should not exist in any of the States to be formed in the territory. But this clause was stricken out before the resolve was passed, and its removal left the measure a mere provision for the political organization of temporary and permanent governments of States, and for the admission of such States into the Union. So far as personal rights or relations were involved in it, the settlers were authorized to adopt, for a temporary government, the constitution and laws of any one of the original States, but the laws were to be subject to alteration by their ordinary legislature. The conditions of their admission into the Union referred solely to their political relations to the United States, or to the rights of the latter as the proprietor of the ungranted lands.
In about a year from the passage of this measure introduced by Mr. Jefferson, and after he had gone on his mission to France, an effort was made by Mr. King to legislate on the subject of the immediate and perpetual exclusion of slavery from the States described in Mr. Jefferson's resolve. Mr. King's proposition was referred to a committee, but it does not appear that it was ever acted upon.[274] The cessions of Massachusetts and Connecticut followed, in 1785 and 1786. Within two years from this period, such had been the rapidity of emigration and settlement, and so inconvenient had become the plan of 1784, that Congress felt obliged to legislate anew on the whole subject of the Northwestern Territory, and proceeded to frame and adopt the Ordinance of July 13, 1787. This instrument not only undertook to make political organizations, and to provide for the admission of new States into the Union, but it also dealt directly with the rights of individuals. Its exclusion of slavery from the territory is well known as one of its fundamental articles, not subject to alteration by the people of the territory, or their legislature.[275]
The power of Congress to deal with the admission of new States was not only denied at the time, but its alleged want of such power was one of the principal reasons which were said to require a revision of the federal system. It does not appear that the subject of legislation on the rights or condition of persons attracted particular attention; nor do we know, from anything that has come down to us, that the clause relating to slavery was stricken from Mr. Jefferson's resolve in 1784, upon the special ground of a want of constitutional power to legislate on such a question. But Mr. Jefferson has himself informed us, that a majority of the States in Congress would not consent to construe the Articles of Confederation as if they had reserved to nine States in Congress power to admit new States into the Union from the territorial possessions of the United States; and that they so shaped his measure, as to leave the question of power and the rule for voting to be determined when a new State formed in the territory should apply for admission.[276] It seems, also, that although the power to frame territorial governments, to organize States and admit them into the Union, was assumed in the Ordinance of 1787, the Congress of the Confederation never acted upon the power so far as to admit a State.[277] Finally, we are told by Mr. Madison, in the Federalist, that all that had been done in the Ordinance by the Congress of the Confederation, including the sale of lands, the organization of governments, and the prescribing of conditions of admission into the Union, had been done "without the least color of constitutional authority";[278]—an assertion which, whether justifiable or not, shows that the power of legislation was by some persons strenuously denied.[279]
With regard to the powers of Congress, under the Confederation, to erect new States in the Northwestern Territory, and to admit them into the Union, the truth seems to be this. There is no part of the Articles of Confederation which can be said to confer such a power; and, in fact, when the Articles were framed, the Union, although it then existed by an imperfect bond, not only possessed no such territory, but it did not then appear likely to become the proprietor of lands, claimed by certain of the States as the successors of the crown of Great Britain, and lying within what they regarded as their original chartered limits. The refusal of those States to allow the United States to determine their boundaries, made it unnecessary to provide for the exercise of authority over a public domain. But in the interval between the preparation of the Articles and their final ratification, a great change took place in the position of the Union. It was found that certain of the smaller States would not become parties to the Confederation, if the great States were to persist in their refusal to cede to the Union their claims to the unoccupied Western lands; and although the States which thus held themselves back, for a long time, from the ratification of the Articles, finally adopted them, before the cessions of Western territory were made, they did so upon the most solemn assertion that they expected and confided in a future relinquishment of their claims by the other States. Those just expectations were fulfilled. By the acts of cession, and by the proceedings of Congress which invited them, the United States not only became the proprietors of a great public domain, but they received that domain upon the express trust that its lands should be disposed of for the common benefit, and that the country should be settled and formed into republican States, and that those States should be admitted into the Union. In these conveyances, made and accepted upon these trusts, there was a unanimous acquiescence by the States.
While, therefore, in the formal instrument under which the Congress was organized, and by which the United States became a corporate body, there was no article which looked to the admission of new States into that body, formed out of territory thus acquired, and no power was conferred to dispose of such lands or govern such territory, there were, outside of that instrument, and closely collateral to it, certain great compacts between the States, arising out of deeds of cession and the formal guaranties by which those cessions had been invited, and with which they had been received, which proceeded as if there were a competent authority in the United States in Congress to provide for the formation of the States contemplated, and for their admission into the Union. Strictly speaking, however, there was no such authority. It was to be gathered, if at all, from public acts and general acquiescence, and could not be found in the instrument that formed the charter and established the powers of the Congress. It was an authority, therefore, liable to be doubted and denied; it was one for the exercise of which the Congress was neither well fitted nor well situated; and it was moreover so delicate, so extensive, and so different from all the other powers and duties of the government, as to make it eminently necessary to have it expressly stated and conferred in the instrument under which all the other functions of the government were to be exercised.[280]
Such was the state of things at the period of the formation of the Constitution; and as we are to look for the germ of every power embraced in that instrument in some stage of the proceedings which took place in the course of its preparation, it is important at once to resort to the first suggestion of any authority over these subjects. In doing so, we are to remember that the United States had accepted cessions of the Northwestern Territory, impressed with two distinct trusts: first, that the country should be settled and formed into distinct republican States, which should be admitted into the Union; secondly, that the lands should be disposed of for the common benefit of all the States.[281]
Accordingly, we find in the plan of government presented by Governor Randolph at the opening of the Convention, a resolution declaring "that provision ought to be made for the admission of States lawfully arising within the limits of the United States, whether from a voluntary junction of government and territory or otherwise, with the consent of a number of voices in the national legislature less than the whole."[282] This resolution remained the same in phraseology and in purpose through all the stages to which the several propositions that formed the outline of the new government were subjected, down to the time when they were sent to the committee of detail for the purpose of having the Constitution drawn out. Looking to the manifest want of power in the Confederation to admit new States into the Union; to the probability that Vermont, Kentucky, Tennessee (then called Franklin), and Maine,—none of which were embraced in any cessions that had then been made to the United States,—might become separate States; and to the prospective legislation of the Ordinance of 1787 concerning the admission of States that were to be formed in the territory northwest of the Ohio, which had been ceded to the Union;—it seems quite certain that the purpose of the resolution was to supply a power to admit new States, whether formed from the territory of one of the existing States, or from territory that had become the exclusive property of the United States. The resolution contained, however, no positive restriction, which would require the assent of any existing State to the separation of a part of its territory; but as the States to be admitted were to be those "lawfully arising," it is apparent that the original intention was that no present State should be dismembered without its consent. But in order to make this the more certain, the committee of detail, in the article in which they carried out the resolution, gave effect to its provisions in these words:—"New States lawfully constituted or established within the limits of the United States may be admitted, by the legislature, into this government; but to such admission the consent of two thirds of the members present in each house shall be necessary. If a new State shall arise within the limits of any of the present States, the consent of the legislatures of such States shall be also necessary to its admission. If the admission be consented to, the new States shall be admitted on the same terms with the original States. But the legislature may make conditions with the new States concerning the public debt which shall be then subsisting."[283]
In the first draft of the Constitution, therefore, there was contained a qualified power to admit new States, whether arising within the limits of any of the old States, or within the territory of the United States. But in this proposition there was a great omission; for although the States to be admitted were to be those lawfully arising, and such a State might be formed out of the territory of an existing State by the legislative power of the latter, yet it was not ascertained how a State was "lawfully to arise" in the territory of the United States. Nor was there, at present, any provision introduced into the Constitution by which Congress could dispose of the soil of the national domain. These as well as other omissions at once attracted the attention of Mr. Madison, who, as we have seen, held the opinion that the entire legislation of the old Congress in reference to the Northwestern Territory was without constitutional authority. Before the article which embraced the admission of new States was reached, he moved the following among other powers:[284] "to dispose of the unappropriated lands of the United States"; and "to institute temporary governments for new States arising therein." These propositions were referred to the committee of detail, but before any action upon them, the article previously reported by that committee was reached and taken up, and there ensued upon it a course of proceeding which resulted in the provisions that now stand in the third section of the fourth article of the Constitution.[285]
The first alteration made in the article reported by the committee was to strike out the clause which declared that the new States should be admitted on an equal footing with the old ones. The reason assigned for this change was, that the legislature ought not to be tied down to such an admission, as it might throw the balance of power into the Western States.[286] The next modification was to strike out the clause which required a vote of two thirds of the members present for the admission of a State.[287] This left the proposed article a mere grant of power to admit new States, requiring the consent of the legislature of any State that might be dismembered, as well as the consent of Congress. An earnest effort was then made, by some of the members from the smaller States, to remove this restriction, upon the ground that the United States, by the treaty of peace with England, had become the proprietor of the crown lands which were situated within the limits claimed by some of the States that would be likely to be divided; and it was urged, that to require the consent of Virginia, North Carolina, and Georgia to the separation of their Western settlements, might give those States an improper control over the title of the United States to the vacant lands lying within the jurisdiction claimed by those States, and would enable them to retain the jurisdiction unjustly, against the wish of the settlers. But a large majority of the States refused to concede a power to dismember a State, without its consent, by taking away even its claims to jurisdiction. It was considered by them, that as to municipal jurisdiction over settlements already made within limits claimed by Virginia, North Carolina, and Georgia, the Constitution ought not to interfere, without the joint consent of the settlers and the State exercising such jurisdiction; that if the title to lands unoccupied at the treaty of peace, lying within the originally chartered limits of any of the States, was in dispute between them and the United States, that controversy would be within the reach of the judicial power, as one between a State and the United States, or it might be terminated by a voluntary cession of the State claim to the Union.[288]
The next step taken in the settlement of this subject was to provide for the case of Vermont, which was then in the exercise of an independent sovereignty, although it was within the asserted limits of New York. It was thought proper, in this particular case, not to make the State of Vermont, already formed, dependent for her admission into the Union on the consent of New York. For this reason, the words "hereafter formed" were inserted in the article under consideration, and the word "jurisdiction" was substituted for "limits."[289] Thus modified, the article stood as follows:—
"New States may be admitted by the legislature into the Union; but no new State shall be hereafter formed or erected within the jurisdiction of any of the present States, without the consent of the legislature of such State, as well as of the general legislature."
This provision was quite unsatisfactory to the minority. They wished to have the Constitution assert a distinct power in Congress to erect new States within, as well as without, the territory claimed by any of the States, and to admit such new States into the Union; and they also wished for a saving clause to protect the title of the United States to vacant lands ceded by the treaty of peace. Luther Martin accordingly moved a substitute article, embracing these two objects, but it was rejected.[290] A clause was then added to the article pending, which declared that no State should be formed by the junction of two or more States, or parts of States, without the consent of the States concerned, as well as the consent of Congress. This completed the substance of what is now the first clause of the third section of the fourth article of the Constitution.[291]
Mr. Carroll thereupon renewed the effort to introduce a clause saving the rights of the United States to vacant lands; and after some modification, he finally submitted it in these words: "Nothing in this Constitution shall be construed to alter the claims of the United States, or of the individual States, to the Western territory; but all such claims shall be examined into, and decided upon, by the Supreme Court of the United States." Before any vote was taken upon this proposition, however, Gouverneur Morris moved to postpone it, and brought forward as a substitute the very provision which now forms the second clause of the third section of article fourth, which he presented as follows: "The legislature shall have power to dispose of, and make all needful rules and regulations respecting, the territory or other property belonging to the United States; and nothing in this Constitution contained shall be so construed as to prejudice any claims, either of the United States or of any particular State." This provision was adopted, without any other dissenting vote than that of the State of Maryland.[292]
The purpose of this provision, as it existed at the time in the minds of the framers of the Constitution, must be gathered from the whole course of their proceedings with respect to it, and from the surrounding facts, which exhibit what was then, and what was afterwards likely to become, the situation of the United States in reference to the acquisition of territory and the admission of new States. There were, then, at the time when this provision was made, four classes of cases in the contemplation of the Convention. The first consisted of the Northwestern Territory, in which the title to the soil and the political jurisdiction were already vested in the United States. The second embraced the case of Vermont, which was then exercising an independent jurisdiction adversely to the State of New York, and the case of Kentucky, then a district under the jurisdiction of Virginia; in both of which the United States neither claimed nor sought to acquire either the title to the vacant lands or the rights of political sovereignty, but which would both require to be received as new and separate States, the former without the consent of New York, the latter with the consent of Virginia. The third class comprehended the cessions which the United States in Congress were then endeavoring to obtain from the States of North Carolina, South Carolina, and Georgia, and in which were afterwards established the States of Tennessee, Mississippi, and Alabama.[293] These cessions, as it then appeared, might or might not all be made. If made, the title of the United States to the unoccupied lands would be complete, resting both upon the cessions and upon the treaty of peace with England; and the political jurisdiction over the existing settlements, as well as over the whole territory, would be transferred with the cessions, subject to any conditions which the ceding States might annex to their grants. If the cessions should not be made, the claims of the United States to the unoccupied lands would stand upon the treaty of peace, and would require to be saved by some clause in the Constitution which should signify that they were not surrendered; while the claims of the respective States would require to be protected in like manner.
The reader will now be prepared to understand the following explanation of the third section of the fourth article of the Constitution. First, with reference to the Northwestern Territory, the soil and jurisdiction of which was already completely vested in the United States, it was necessary that the Constitution should confer upon Congress power to exercise the political jurisdiction of the United States, power to dispose of the soil, and power to admit new States that might be formed there into the Union. Secondly, with reference to such cases as that of Vermont, it was necessary that there should be a power to admit new States into the Union without requiring the assent of any other State, when such new States were not formed within the actual jurisdiction of any other State. Thirdly, with reference to such cases as that of Kentucky, which would be formed within the actual jurisdiction of another State, it was necessary that the power to admit should be qualified by the condition of the consent of that State. Fourthly, with reference to such cessions as were expected to be made by North Carolina, South Carolina, and Georgia, it was necessary to provide the power of political government, the power to admit into the Union, and the power to dispose of the soil, if the cessions should be made; and at the same time to save the claims of the United States and of the respective States as they then stood, if the cessions anticipated should not be made. None of these cases, however, were specifically mentioned in the Constitution, but general provisions were made, which were adapted to meet the several aspects of these cases. From the generality of these provisions, it is held by some that the clause which relates to "the territory or other property of the United States," was intended to be applied to all cessions of territory that might ever be made to the United States, as well as to those which had been made, or which were then specially anticipated; while others give to the clause a much narrower application.[294]
There now remain to be considered the restraints imposed upon the exercise of the powers of Congress, both within the States and in all other places; both where the authority of the United States is limited to certain special objects, and where it is unlimited and universal, excepting so far as it is narrowed by these constitutional restraints. Some of them I have already described, in tracing the manner in which they were introduced into the Constitution. We have seen how far the commercial and revenue powers became limited in respect to the slave-trade, to taxes on exports, to preferences between the ports of different States, and to the levying of capitation or other direct taxes. These restrictions were applicable to these special powers. But others were introduced, which apply to the exercise of all the powers of Congress, and are in the nature of limitations upon its general authority as a government.
One of these is embraced in the provision, "that the privilege of the writ of habeas corpus shall not be suspended, unless when, in cases of rebellion or invasion, the public safety may require it."[295] The common law of England, which recognizes the right to the writ of habeas corpus for the purpose of delivery from illegal imprisonment or restraint, was the law of each of the American States; and it appears from the proceedings of the Convention to have been the purpose of this provision to recognize this right, in the relations of the people of the States to the general government, and to secure and regulate it. The choice lay between a declaration of the existence of the right, making it inviolable and absolute, under all circumstances, and a recognition of its existence by a provision which would admit of its being suspended in certain emergencies. The latter course was adopted, although three of the States recorded their votes against the exception of cases of rebellion or invasion.[296]
The prohibition upon Congress to pass bills of attainder, or ex post facto laws, came into the Constitution at a late period, and while the first draft of it was under consideration. Bills of attainder, in the jurisprudence of the common law, are acts of legislation inflicting punishment without a judicial trial. The proposal to prohibit them was received in the Convention with unanimous assent. With regard to the other class of legislative acts, described as "ex post facto laws," there was some difference of opinion, in consequence probably of different views of the extent of the term. In the common law, this expression included only, then and since, laws which punish as crimes acts which were not punishable as crimes when they were committed. Laws of a civil nature, retrospective in their operation upon the civil rights and relations of parties, were not embraced by this term, according to the definition of English jurists. But it is manifest from what was said by different members, that, at the time when the vote was taken which introduced this clause into the Constitution, the expression "ex post facto laws" was taken in its widest sense, embracing all laws retrospective in their operation. It was objected, therefore, that the prohibition was unnecessary, since, upon the first principles of legislation, such laws are void of themselves, without any constitutional declaration that they are so. But experience had proved that, whatever might be the principles of civilians respecting such laws, the State legislatures had passed them, and they had been acted on. A large majority of the Convention determined, therefore, to place this restraint upon the national legislature, and at the time of the vote I think it evident that all retrospective laws, civil as well as criminal, were understood to be included.[297] But when the same restraint came afterwards to be imposed upon the State legislatures, the attention of the assembly was drawn to the distinction between criminal laws and laws relating to civil interests. In order to reach and control retrospective laws operating upon the civil rights of parties, when passed by a State, a special description was employed to designate them, as "laws impairing the obligation of contracts," and the term "ex post facto laws" was thus confined to laws creating and punishing criminal offences after the acts had been committed.[298] What is now the settled construction of this term, therefore, is in accordance with the sense in which it was finally intended to be used by the framers of the Constitution before the instrument passed from their hands.
The committee of detail had reported in their draft of the Constitution a clause which restrained the United States from granting any title of nobility. The Convention, for the purpose of preserving all officers of the United States independent of external influence, added to this a provision that no person holding an office of profit or trust under the United States shall, without the consent of Congress, accept of any present, emolument, office, or title, of any kind whatever, from any king, prince, or foreign state.[299]
In addition to the special powers conferred by the Constitution upon the national government, it has imposed certain restraints on the political power of the States, which qualify and diminish what would otherwise be the unlimited sovereignty of each of them. These restraints are of two classes;—a part of them being designed to remove all obstructions that might be placed by State legislation or action in the way of the appropriate exercise of the powers vested in the United States, and a part of them being intended to assimilate the nature of the State governments to that of the Union, by the application of certain maxims or rules of public policy. These restraints may now be briefly examined, with reference to this classification.
The idea of imposing special restrictions upon the power of the separate States was not expressly embraced in the plan of government described by the resolutions on which the committee of detail were instructed to prepare the instrument of government. Such restrictions, however, were not unknown to the previous theory of the Union. They existed in the Articles of Confederation, where they had been introduced with the same general purpose of withdrawing from the action of the States those objects, which, by the stipulations of that instrument, had been committed to the authority of the United States in Congress. But the inefficacy of those provisions lay in the fact, that they were the mere provisions of a theory. The step now proposed to be taken was to superadd to the prohibitions themselves the principle of their supremacy as matters of fundamental law, and to enable the national judiciary to make that supremacy effectual.
Almost all the restraints imposed by the Articles of Confederation upon the States could be removed or relaxed by the consent of the Congress to the doing of what was otherwise prohibited. In the first draught of the Constitution, the committee of detail inserted four absolute prohibitions, which could not be removed by Congress itself. These related to the coining of money, the granting of letters of marque and reprisal, the making of treaties, alliances, and confederations, and the granting of titles of nobility. All the other restraints on the States were to be operative or inoperative, according to the pleasure of Congress.[300] Among these were included bills of credit; laws making other things than specie a tender in payment of debts; the laying of imposts or duties on imports; the keeping of troops or ships of war in time of peace; the entering into agreements or compacts with other States, or with foreign powers; and the engaging in war, when not invaded, or in danger of invasion before Congress could be consulted. The enactment of attainder and ex post facto laws, and of laws impairing the obligation of contracts, was not prohibited at all.
But when these various subjects came to be regarded more closely, it was perceived that the list of absolute prohibitions must be considerably enlarged. Thus the power of emitting bills of credit, which had been the fruitful source of great evils, must either be taken away entirely, or the contest between the friends and the opponents of paper money would be transferred from the State legislatures to Congress, if Congress should be authorized to sanction the exercise of the power. Fears were entertained that an absolute prohibition of paper money would excite the strenuous opposition of its partisans against the Constitution; but it was thought best to take this opportunity to crush it entirely; and accordingly the votes of all the States but two were given to a proposition to prohibit absolutely the issuing of bills of credit.[301] To the same class of legislation belonged the whole of that system of laws by which the States had made a tender of certain other things than coin legal satisfaction of a debt. By placing this class of laws under the ban of a strict prohibition, not to be removed by the consent of Congress in any case, the mischiefs of which they had been a fruitful source would be at once extinguished. This was accordingly done, by unanimous consent.[302]
At this point, the kindred topic of the obligation of contracts presented itself to the mind of Rufus King, suggested doubtless by a provision in the Ordinance then recently passed by Congress for the government of the Northwestern Territory.[303] The idea of a special restraint on legislative power, for the purpose of rendering inviolate the obligation of contracts, appears to have originated with Nathan Dane, the author of that Ordinance. It was not embraced in the resolve of 1784, reported by Mr. Jefferson, which contained the first scheme adopted by Congress for the establishment of new States in the Northwestern Territory; and it first appears in our national legislation in the Ordinance of 1787. Its transfer thence into the Constitution of the United States was a measure of obvious expediency, and indeed of clear necessity. In the Ordinance, Congress had provided a system of fundamental law, intended to be of perpetual obligation, for new communities, whose legislative power was to be moulded by certain original maxims of assumed justice and right. The opportunity thus afforded for shaping the limits of political sovereignty according to the requirements of a preconceived policy, enabled the framers of the Ordinance to introduce a limitation, which is not only peculiar to American constitutional law, but which, like many features of our institutions, grew out of previous abuses.
In the old States of the Confederacy, from the time when they became self-governing communities, the power of a mere majority had been repeatedly exercised in legislation, without any regard to its effect on the civil rights and remedies of parties to existing contracts. The law of debtor and creditor was not only subjected to constant changes, but the nature of the change depended in many of the States upon the will of the debtor class, who formed the governing majority. So pressing were the evils thus engendered, that, when the framers of the Ordinance came to provide for the political existence of communities whose institutions they were to dictate, they determined to impose an effectual restraint on legislative power; and they accordingly provided, in terms much more stringent than were afterwards employed in the Constitution, that no law should have effect in the Territory which should in any manner whatever interfere with or affect private contracts or engagements previously made.[304]
The framers of the Constitution were not engaged in the same work of creating new political societies, but they were to provide for such surrenders by existing States of their present unquestioned legislative authority, as the dictates of sound policy and the evils of past experience seemed to require. When this subject was first brought forward in the Convention, the restriction was made to embrace all retrospective laws bearing upon contracts, which were supposed to be included in the term "ex post facto laws." It being ascertained, however, that the latter phrase would not, in its usual acceptation, extend to civil cases, it became necessary to consider how such cases were to be provided for, and how far the prohibition should extend. The provision of the Ordinance was regarded as too sweeping; no legislature, it was said, ever did or can altogether avoid some retrospective action upon the civil relations of parties to existing contracts, and to require it would be extremely inconvenient. At length, a description was found, which embodied the extent to which the prohibition could with propriety be carried. The legislatures of the States were restrained from passing any "law impairing the obligation of contracts";—a provision that has been found amply sufficient, and attended with the most salutary consequences, under the interpretation that has been given to it.[305]
Bills of attainder and ex post facto laws, which had not been included in the prohibitions on the States by the committee of detail, were added by the Convention to the list of positive restrictions, which was thus completed.
In the class of conditional prohibitions, or those acts which might be done by the States with the consent of Congress, the committee of detail had placed the laying of "imposts or duties on imports." To this the Convention added "exports," in order to make the restriction applicable both to commodities carried out of and those brought into a State. But this provision, as thus arranged, would obviously make the commercial system extremely complex and inconvenient. On the one hand, the power to lay duties on imports had been conferred upon the general government, for the purposes of revenue, and to leave the States at liberty, with the consent of Congress, to lay additional duties, would subject the same merchandise to separate taxation by two distinct governments. On the other hand, if the States should be deprived of all power to lay duties on exports, they would have no means of defraying the charges of inspecting their own productions. At the same time, it was apparent that, under the guise of inspection laws, if such laws were not to be subject to the revision of Congress, a State situated on the Atlantic, with convenient seaports, could lay heavy burdens upon the productions of other States that might be obliged to pass through those ports to foreign markets. Again, if the States should be deprived of all power to lay duties on imports, they could not encourage their own manufactures; and if allowed to encourage their own manufactures by such State legislation, it must operate not only upon imports from foreign countries, but upon imports from other States of the Union, which would revive all the evils that had flowed from the want of general commercial regulations. To prevent these various mischiefs, the Convention adopted three distinct safeguards. They provided, first, by an exception, that the States might, without the consent of Congress, lay such duties and imposts as "may be absolutely necessary for executing their inspection laws"; second, that the net produce of all duties and imposts laid by any State, whether with or without the consent of Congress, shall be for the use of the Treasury of the United States; third, that all such State laws, whether passed with or without the previous consent of Congress, shall be subject to the revision and control of Congress.[306] There is, therefore, a twofold remedy against any oppressive exercise of the State power to lay duties for purposes of inspection. The question whether the particular duties exceed what is absolutely necessary for the execution of an inspection law, may be made a judicial question; and in addition to this, the law imposing the inspection duty is at all times subject to the revision and control of Congress. Any tendency to lay duties or imposts for purposes of revenue or protection, is checked by the requirement that the net produce of all duties or imposts laid by any State on imports or exports shall be paid over to the United States, and such tendency may moreover be suppressed by Congress at any time, by the exercise of its power of revision and control.
In order to vest the supervision and control of the whole subject of navigation in Congress, it was further provided that no State, without the consent of Congress, shall lay any duty of tonnage. An exception, proposed by some of the Maryland and Virginia members, with a view to the situation of the Chesapeake Bay, illustrates the object of this provision. They desired that the States might not be restrained from laying duties of tonnage "for the purpose of clearing harbors and erecting light-houses." It was perhaps capable of being contended, that, as the regulation of commerce was already agreed to be vested in the general government, the States were restrained by that general provision from laying tonnage duties. The object of the special restriction was, to make this point entirely certain; and the object of the proposed exception was to divide the commercial power, and to give the States a concurrent authority to regulate tonnage for a particular purpose. But a majority of the States considered the regulation of tonnage an essential part of the regulation of trade. They adopted the suggestion of Mr. Madison, that the regulation of commerce was, in its nature, indivisible, and ought to be wholly under one authority. The exception was accordingly rejected.[307]
The same restriction, with the like qualification of the consent of Congress, was applied to the keeping of troops or ships of war in time of peace, entering into agreements or compacts with another State or a foreign power, or engaging in war, unless actually invaded or in such imminent danger as will not admit of delay.[308]
