Brown and Others, Plaintiffs in Error, against The State of Maryland, Defendant in Error.
An act of a State legislature, requiring all importers of foreign-goods by the bale or package, &c. and other persons selling the same by wholesale, hale, or package, &c. to take out a license, for which they shall pay 50 dollars, and in ease of neglect or refusal' to take out such license, subjecting them to certain forfeitures and penalties, is repugnant to that provision of the constitution of the United States, which declares, that “ no State shall, without the consent of Congress, lay any impost, or duty on imports or exports, except what may be absolutely necessary for executing its inspection lawsand to that which declares that Congress shall have power “ to regulate commerce with foreign nations, among the several States, and with the Indian tribes.”
ERROR to the Court of Appeals of Maryland.
This was an indictment in the City Court of Baltimore, against the plaintiffs in error, upon the second section of an act of the legislature of the State of Maryland, passed in 1821, entitled, “¡An act supplementary to the act laying duties on licenses to retailers of dry goods, and for other purposes.” ' The second section of the act provides, “ That all importers of foreign articles, or commodities, of dry goods, wares, or merchandises, by bail or package, or of wine, rum, brandy, whiskey, and other distilled spirituous liquors, &c. and other persons selling the same by whole sa*ei bale» or package, hogshead, barrel, or fierce, shall, be ■ lore they are authorized to sell, take out a license as by the original act.is directed, for which they shall pay fifty dollars; and in case of neglect or refusal to take out such license, shall be subject to the same penalties an I forfeitures as arc prescribed by the original act, to which this is a supplement.” The penalties and forfeitures prescribed by the original act, which was passed in 1819, were, a forfeiture os the amount of the license tax, and a fine of 100 dollars, to be recovered by indictment.
Feb. 28th.
The defendants having demurred to the indictment, a judgment was rendered upon the demurrer against them, in the City Court, which was affirmed in the Court of Appeals, and the case was brought, by writ of error, to Ibis Court,
Mr. Meredith, for the plaintiffs in. error,
contended, that' the law in question was an unconstitutional exercise of the taxing power of Maryland. He did not deny the existence of such a power. As a necessary incident to sovereignty, it belonged to the several States before the adoption of the constitution, and it still belongs to them, subject, however, to the restrictions imposed upon its exercise by the paraimount authority of that instrument. With regard to .these Restrictions, he did not mean to contend, thuf the general .grant contained in the eighth section of the first article of the constitution, vested in the national government any thing more than a concurrent power of taxation, fie admitted the rule- of construction, that a grant of power to Congress does not, of itself, imply a prohibition of its exercise by the Slates. The powers granted to (he general government are never to be considered as exclusive, unless they are made so in express terms, or unless, from the nature of the power itself, its concurrent exercise must necessarily produce direct repugnancy or incompatibility. But he argued, that this was by no means the inevitable result from a concurrent exercise of the taxing power, because its peculiar nature rendered it often capable of being exercised by different authorities at the same time, and even upon the same subject, without actual collision or interference.
The restrictions which he had alluded to , were, to be found m other provisions of the constitution; and they were both express and implied. The former were all comprised in the tenth section of the first article, by which the States are prohibited, unless with the consent of Congress, from laying any imposts or duties oh imports or exports, except what may be absolutely necessary for executing their inspection laws; and are, also, without such consent, forbidden to impose any duty upon tonnage. The effect of this prohibition, coupled with the general grant of the taxing power before referred to, is to vest in the national government an exclusive right to the commercial imposts of the country. With the exception of these, however, the power to lay and collect taxes is a concurrent power.
But, like all the other concurrent powers of the States, this power of taxation is subject, in its exercise, to that general implied restriction which necessarily results from the supreme and paramount authority of the Union. This is a vital principle of the political system, and its direct opera ■ tion is to restrain the States from the exercise of any power’ repugnant to, or incompatible with, the constitution, or the constitutional laws of the national government. By which is to be understood, not merely a repugnancy growing our of a concurrent exercise, of the same power by Congress and a State legislature, but that which may arise from the exercise of one power by a State, with reference to a different power, whether exclusive or concurrent, express or implied, residing in the general government.
Having stated and illustrated the«e as the constitutional limits of the taxing power of the States, he insisted, that they had been transgressed by the legislative act under consideration. The second section comprises all the provisions of the law which are material to the. question. The true' construction of this section is somewhat doubtful; upon any interpretation,- however, it prohibits the importer from selling the imported merchandise without having first taken out a license to do so, for which he is required to pay a stipulated tax.
The question then is, whether this is such a law as the legislature of Maryland have a righ* to pass. Under colour of 0 license law. he contended that this statute was a palpable evasion of the express restriction upon the States to “lay duties on importsan indirect attempt to do that which the constitution has explicitly inhibited. And he said this, because he'thought it might be clearly shown, that a law, laying a tax on the importer for'lhe privilege of selling the merchandise he has himself imported, which is this law, and this case, is equivalent, in all substantial respects, to a duty on imports, since, with a few slight and unimportant differences, it answers all the purposes, and produces all the effects of a concurrent power in the States to impose such a duty.
.What are the apparent differences between this and a tax directly on imports ? It may be said, in the first place, that the one is a tax for the privilege ofbringing the foreign article into the country, and the other a tax for the privilege of selling it aftér it is so brought in. ' But these privileges are indissolubly connected; the right to sell is a necessary incident to the right of importing. The grant of á privilege to import would bé of no value, unless it implies a right to sell. Prohibit sale, and importation necessarily ceases. He maintained that, on a fair and just construction of the whole revenue system, thé implication was irresistible. That the duties exacted by the general government were paid, not for the privilege to import simply, but for the privilege of importing foreign commodities, and using them in the way of merchandise, might be incontestably proved, by showing that no goods were dutiable, unless imported with the intention, and for the purpose of traffic. With this view, he referred to various provisions of the act of March, 1799, (ch. 128. s. 30. 32. 45, 46. 60. and 107.) and to the case o£ the Concor:d. This is the principle, also, of the English law of customs, from which our system is mainly borrowed. It-was likewise worthy of remark, that the legislation of Maryland, upon this subject, before the adoption of the constitution, was in strict accordance with the same principle, and carried it so far as to permit the merchant to try the market by an actual sale, and paying the duties only on the portion sold, to export the residue free of duty. There is, then, no difference in this respect between these two modes of taxation.
It may be said that these taxes are payable at different times; in the one case, at the time of 'importation, in the other, at the time of sale. But if they are both paid substantially for the same privilege, surely this is not a material difference. It is a matter that simply concerns the safety, certainty, and convenience of collection; but it gives no distinctive character to the law. In point of fact, however, the duty imposed by the revenue system is not payable, except it is less than fifty dollars, until after the importation.
A third apparent difference may be said to consist in this: that the import duty is a charge upon the goods, the license upon the person; but the one is as much a charge upon the goods as the other, if by that is meant an increase of their actual cost. The import duty is, however, a personal charge, upon the importer; it is not the bond that alone makes him personally liable ; without' having given a bond, he is still answerable for the duties.
These are the only differences in the operation of the two taxes, and they are apparent, but not substantial; they are the disguise thrown about the law to elude detection. The true test, however, is, to consider the effect of this law upon the exclusive grant to the general government, to raise', revenue from imposts. The reasons for such a grant arc obvious. The objects committed by the constitution to the general government are of immense magnitude, and require corresponding means. Of ail species of taxation, that upon imports is most fruitful and least oppressive. It is sound policy, therefore, to cherish and extend this branch of the public revenue; because, whenever it fails, other modes of taxation must necessarily be resorted to of a more odious and 1 oppressive nature. Now, the consequence of the right claimed by this law on the part of Maryland, is, to place this branch of the public revenue completely in her power; as entirely so, as if she had constitutionally a concurrent right
to tax imports. It is to enable her, at her pleasure, by means of license laws, to annihilate, as it regards her own territory, the commercial revenues of the country. What is to ¡prevent her from' prohibiting altogether the importation of foreign merchandise into any of her ports ? It is only to increase the price of the license until the commodity will no longer bear the burden, and the end is accomplished. Importation must, in that case, necessarily cease, and with it revenue. It is not pretended that these consequences are produced by this particular law; it is not necessary that this should be the case. We are not to look at the particular exercise of power so much as at the principle upon which the power is assert ■ ed. We are not to judge of the constitutionality of this law by the amount of tax which it imposes; it is not the degree of taxation, in the particular instance, that determines the right to tax. That the public revenue is, to a certain degree, affected by the operation of this law, is incontestable, .But if, on principle, Maryland has a right to demand fifty dollars as the price of a license to sell imported merchandise, she has a right to demand any sum for the same privilege. If, in other words, she is within the proper sphere of her taxing power, that power is, in its nature, unlimited, and she may carry it to what extent she pleases. A power to tax, this Court has emphatically said, is a power to destroy. In this case, it is a power to prohibit ; a power to deprive the government of the means to accomplish its great objects, and conduct all its important operations ; a power to defeat the intention of the exclusive grant of commercial revenue.
If Maryland has a fight to enact laws of this description, she has a right to regulate her own foreign commerce, although, by the constitution, it is exclusively vested in Congress. The imposition of import duties is often resorted to. not for the purpose of revenue, but to regulate commercial intercourse with foreign countries. Discriminating duties, protecting duties, prohibitory duties, are so many commercial regulations. These may all be resorted to under the disguise of license laws. If Maryland has a right to pass general license laws, she may pass partial ones; she may select particular commodities, and burthen their sale with a license duty : she may establish a tariff of discriminating duties fpr herself, and affect, if not defeat, the commercial policy of the country. In one word, she may exercise the same right to regulate commerce by means of license laws, which a concurrent power to tax imports would give her, .and thus evade, in this respect also, the constitutional projhibition. It may be said; that this law looks to no such object ; that it is simply a tax for .revenue, and that there is no ground to apprehend that it will be used for any other pur-, pose. But the motives for legislative acts are not fit subjects of judicial inquiry. If the power can be exercised for one purpose, it may be for another; the intention may always be effectually concealed. .It is the principle of the law, and its capacity to be exerted for the attainment of other objects than that which it professes to aim at in the particular case, that it is proper and necessary to look to. If the States are authorized to pass laws of this description, the purposes which 'induced the prohibition are defeated, and it is rendered altogether nugatory.
Mr. Taney and Mr. Johnson, contra,
insisted, that the law of Maryland did not lay a duty on imports, and was not repugnant to the constitution of the United States.
The act of assembly (they said) does not impose a tax on the importation of foreign goods, nor upon the trade and occupation of an importer. But the tax is imposed upon the trade and occupation of selling foreign goods by wholesale after they have been imported. It is a tax upon the profession or trade of the party, when that trade is carried on within the State. It is laid upon the same principle with the usual taxes on retailers, or innkeepers, or hawkers and pedlars, or upon any other trade exercised within the State. It is true, the importers of foreign goods are, by express words, made subject to the provisions of this law, provided they sell by wholesale; but it is the selling by wholesale which subjects. the party to the tax; it is upon that trade that the tax is imposed.
Does tl'' constitution of the United States forbid Maryland to impose such a tax ? This' is the only question presented by -the record.
The plaintiffs in error insist, that the tax in question is Virtually a duty on imports, and violates that clause in the constitution which declares that a State shall not lay duties, on imports.
Wc answer, it is not, either directly or indirectly, a duty on imports. A duty on imports is a tribute paid to the sovereignty of the country for permission to introduce foreign goods. To import, and to bring in, mean the same thing. A duty on imports is, therefore, a duty on the bringing in- of foreign goods — on the act of importation. The duty is paid for the permission to introduce them ; it is the consideration given for that privilege. The party buys the right to introduce the goods into the United States, and .to place them'under the protection of the laws of the country. He becomes liable to the whole duty by the very act of importation ; and the amount is the same, whether he proposes to sell the goods, or to keep them for his own use, or to give them as a present to another.
' After the goods have been brought into a State, the importer has one peculiar relation to them by reason of his being the importer. He is known to the State Jaws in the character of owner, or as the party entitled to the custody of the goods, and he receives the same degree of protection whether he be the importer or not the importer. The property, when it has passed through the custom houses, is no longer under the exclusive protection of the United States. It is guarded by the laws of the State — must be transferred and otherwise dealt with, according to the laws of the State, it is, therefore, imported, or brought in, and the act of importation is completed. If, therefore, a duty op imports means a duty on the act of importation, or the permission to introduce, it is very'clear, that the law in. question' is not, directly or indirectly, a duty on imports.
But, it is said, that the word “ imports,” as used in the constitution of the United States, does not mean importation, but means the goods imported.
If this interpretation be right, then the constitution of 'the United States must be expounded as if it had said, “JVb State shall, without the consent of Congress, lay any imposts or duties on goods imported.” And if such be the true reading of the constitution, then no State can lay a tax upon any article of property which was imported from a foreign country. According to this construction, imported plate, imported furniture, imported property of every kind, would be privileged property, and exempt from taxation by the-States. For, if the word 11 imports f as used in the constitution, means “ goods imported,” or “ imported goods,” then the States, without the permission of Congress, cannot tax property within their dominion, and owned by their citizens, provided that property has been' introduced from abroad. Such would be the inevitable consequence of expounding.the word imports as if the words !< imported goods” had been used. The uniform practice of the States,' the principles of justice, the interests of the community, are all directly opposed to this construction.
But, it is said, that if “ imports” means importation, and not the goods imported, yet the privilege of selling is inseparably incident to the importation, and is always implied in the privilege-to import. This argument, like the one last replied to, will be found to prove too much, and to lead to results that can hardly be acquiesced in.
The right to import foreign goods is derived from the United States. The duties are imposed by the federal government, and are paid to that sovereignty. The permission to,import is conferred by that government, and if the right to sell is implied in the permission to import, then the . right to sell is derived from the United States, and becomes an absolute and vested right in the importer as soon as he acquires the privilege .of introducing the goods ; that is, as soon as he pays the duties, or secures them, according to the acts of Congress. And if the right to sell is a .vested right, derived from the general government, then this right cannot be limited, restrained, regulated, or in any manner affected by State legislation. The importer, .then, having an absolute and unconditional right to sell, may sell in anyplace, and in any manner he thinks proper. He may. offer for sale large quantities of gunpowder in the heart of a city. and thus endanger the lives of the citizens; he may offer hides, lish, and articles of that description, in places offens¡ve an(j inconvenient to the public, and dangerous to the health of the citizens; he may hold an auction at his own warehouse, and refuse to pay any tax to the State ; he may sell at retail; he may sell as a hawker and pedlar; and the laws of the States which impose taxes on these trades, are unconstitutional and void, so far as the importer is concerned. These taxes have been always imposed by some of the States, and their right to derive a revenue from these sources has never before been questioned.
it may be said, that the right of the importer to sell, is.h right to sell by wholesale only, and not by auction, or by retail. If, however, the right exists at all, it cannot be limited to sales by wholesale. It is said' to be incident to the permission to import; and if it be annexed to that permission, then it must be an absolute and unconditional right: for where can we find the qualification ? If the States are disabled from imposing a tax on the sales of foreign merchandise, when made by the bale or package, why are they not equally unable to impose a tax on the sales of such goods when made by auction, or retail, or in any other man'ner? The constitution gives no peculiar privilege to any particular mode of sale; and this Court, in expounding the instrument, will not introduce into it new limitations, and new divisions of power, not implied by its words.
In fine, the importer, by the payment of the duties, either acquires the right to sell, as well as the right to introduce Ihe goods, or he acquires the right to bring in merely.__In the first case, his right to sell would be beyond the reach of State control, and State regulation. In the second case, the goods would be subject to the laws and authority of the State. It-can hardly be held, that an importer may sell in any place, and in any manner he pleases ; and if he may not, it is because the disposition of the goods is subject to tbe regulations of the State authorities; and if they are so subject, they are, consequently, liable to such burthens as the State may impose on any particular mode of sale or transfer; and, therefore, liable to the tax in question.
The cases cited of goods wrecked on our shores, can hardly be supposed to bear on this argument. To import, implies an act of the will, a voluntary introduction of the goods. Besides, in those cá'ses, the question is, are the goods liable to pay duty ? not what rights will the payment of the duty procure ? And when the questions are so different, it is not perceived how a decision of the one can in any degree affect the other. .
But, it is insisted, on the other side, that if the law in. question be not repugnant to that clause in the constitution which forbids a State to lay a duty on imports, yet it is in violation of that clause which gives Congress the power to regulate commerce with foreign nations. It must be observed, that this argument admits, argumenli gratia, that the tax in question:is not, either directly or indirectly, a duty on imports. But the plaintiffs in error contend, that although it be not a duty on imports, still the tax in question is forbidden by the constitution of the United States. In other words, they maintain, that the tenth section in the constitution of the United States is not the only one which limits the taxing power of the States 5 and that this power is still further curtailed by the clause which gives Congress the power-to regulate commerce.
It has been settled by the decisions of this Court, that the grant of ¿power to Congress, does'not extinguish the right of the States to legislate on the same subject, unless Congress exercises the power granted. And. when the power is exercised, the States may.yet legislate, if the whole ground of legislation has not been covered by the laws of the United States provided the Slate law be not repugnant to that of the federal government. Assuming these principles as settled, it would be a sufficient answer to this argument to say, that no law of Congress gives, or professes to give to the importer, the right to sell: The revenue laws referred to, charge duties in certain cases, where sales may be made, The laws are framed on the assumption that certain foreign goods will be permitted to be sold; but these laws do not give that permission generally, nor point out in what mode they may be sold. If, therefore, under this power to regulate commerce, Congress may give the importer a right to sell,yet.the right is not given; and until it is given by Con gress, the States may regulate and tax the sales without violating the constitution of the United States.
• But this clause in the constitution does not give to Congress the power contended for. By the constitution of the United States, the power of taxation by the States is restrained, by express words, in certain cases.
It has always been supposed, that these limitations of State sovéreignty, in matters of revenue, so carefully and particularly set down, excluded all inference and implication, and left with the States all the powers of taxation not expressly denied to them in the restraining section.- It is very clear, that the men who framed the constitution, and the people who adopted the constitution, so understood it. The Federalist must be considered as expressing the opinions of the friends of the federal constitution, both in and out of the Convention; and in No. 33, and near the conclusion of that number, the commentary on the subject of the taxing power is thus concluded: “ The inference from the whole is, that the individual States would, under the proposed constitution, retain an independent and uncontrollable authority to raise revenue to any extent of which -they may stand in need, by every kind of taxation, except duties on imports and exports.53 And,'throughout No. 32 and No. 33 of the Federalist, the same principle is repeatedly asserted as a clear and indisputable one.
But, if Congress, under the power to reguláte commerce, may authorize the. importer to sell, then certain important powers of taxation, besides duties on imports and exports, have been surrendered by the States. For if Congress may give by law to the importer the right to sell, Congress may direct how the sale may be made, or may allow the importer to elect any mode he pleases; aiid, whenever this shall, be done by the general government, thé power of the States to regulate such sales is at an end,' and, consequently, their power of taxation also. If this argument, then, be sustained by the Court, the' authority of the States to regulate' and to tax auctioneers and retailers is not “ an independent and uncontrollable authority,” as was supposed by the distinguished writers in the Federalist, but is a mere dependent authority, and liable to the control of Congress, so far. as fo reign goods are concerned. Congress, it is said, may. give the importer the right to sell. , If Congress may do so, then the States cannot tax any mode of sale which Congress may please to permit. Such, powers were surely too important and valuable to have been surrendered in this loose and slovenly manner. If they were to have beén given up by the States, they would have been given up in express terms, like the duties on imports, and not by vague and uncertain inferences. Besides, if Congress may give the right to sell in any manner, they may also give the right to sell in any place ; and the police laws of the different States, made for their safety of health, exist only by the permission of- Congress. And again, if Congress may not only prescribe the terms upon which foreign goods may be introduced into the country, but may direct how they shall be sold, and thus exempt the sales from State taxation, why may not Congress, upon the same principle, exempt all foreign goods from taxation by the Stales ? If Congress may .exercise exclusive dominion over foreign goods, for one purpose, after they have béen brought into a State, why may not the same exclusive power be exercised for any other purpose ? Reasons of policy might, indeed, make a difference; but we are not now discussing the policy of introducing new provisions into the eonstuution, but endeavouring to ascertain the meaning of the words used in the instrument.
The lastargument urged iu behalf of the plaintiff in error, is founded on the supposed policy and objects of the constitution, rather than on the interpretation of any words used in the instrument itself. It is said, that if a State may impose the tax in question, it may increase it to any amount, and by that means the States may prevent importations altogether. And, hence it is inferred, that a power capable of being so much abused, was not intended to have been left with the States.
.Nothing can.be more fallacious than to urge the possible abuse of power by the States, for the purpose of proving that the power has been- taken away. Such an argument goes to the destruction of all State power. Such a principle of construction would put an end to all State authority; for all power may possibly be abused. The States cannot and ought not to be deemed more liable than the federal govern-* meet to abuse the powers confided to them by the people 5 nor Gan any supposed-and merely possible inconvenience, which might arise from an improper use of State power, furDjsh a groand for deciding against the existence of the power. We must be continually liable to this inconvenience from the complex character of our government. In the Federalist, , No. 32, the rule of construction is thus stated: “ It is not a mere possibility of inconvenience in the exercise of powers, but an immediate and constitutional, repugnancy, that can, by implication, alienate and extinguish a pre-existing right' 'of sovereignty.” The possibility of inconvenience from the improper use of this power by the States, is not, therefore, any argument against the existence .of this power, It cannot, by implication, alienate and extinguish the pOWer for which we are contending.
But, indeed, it is impossible that the power to lay the tax in question can lead to any inconvenience, or can be used to embarrass the regulations, of lessen the revenue of the federal government. If.the tax on wholesale dealers should be so heavy as to prevent importations, the people of the Státe will be the principal sufferers. - If it enhances the price of imported goods, the hurthen is at least as heavy on the people of the State as it is on the citizens of other States, and this furnishes abundant security that no such tax will ever be vexatiously laid. The people of a State cannot be justly suspectedof imposing heavy burthens upon themselves, for the purpose of thwarting or embarrassing the general government. If, indeed, the people of a State could be guilty ©f such folly, they might,'by bounties and other facilities to manufacturers in their own State, effectually- prevent the importation of foreign goods. Nobody would deny that the States possess this power; but nobody suspects them of being disposed to abuse it.
There is, indeed, no real dangey of serious inconvenience from these ' conflicting powers. The good Isense and good feelings of the people will always apply the remedy; and we may safely confide, that the'State governments,- and the general government, will never embark in the unprofitable contest of trying which shall doéaeh other the most harm. But if such a state of things should ever tqke place, it would matter very little how the boundaries of power had been marked out by judicial decision. The Union cannot be preserved by the mere strength and power of the federal government. It is dissolved as soon as'it shall forfeit the affection and confidence of the States.
The Attorney General, for the plaintiffs in error, in reply,
stated the question, to be, whether a State law, which rendered it criminal to import and sell foreign goods, without the permission of the State, which peri fission was only to be obtained by paying a tax to the State, was repugnant to the constitution, laws, and treaties of the Union. If the State of Maryland had the power to lay such a restraint on the importation and sale of foreign goods, every other State must have the same power; and the consequence would be, that this power of taxation would directly, interfere; both, with the power of regulating commerce, and with the taxing power of Congress. The quantum of tax imposed by the State could make no difference. The same principle would apply, as in the attempt Of the same State to tax the Bank of the United States, where theCoirt held, that a power to tax, was a power to tax limited ony by the pleasure of the State; and that it was,, 'therefore, a power, to destroy.
In the present case, the power was denied upon two grounds; first, because the power' exerted by'the law in question is that of regulating commerce with foreign nations, and among the several States, which the Court has determined to be exclusively vested in Congress ' Secondly, because it was that.of laying an impost, or duty on imports, without the consent of Congress.
In order to determine whether the present law interfered with the exercise of the power of regulating commerce, it was only necessary to see whether it undertook to prescribe file terms on which commerce may be carried on with fr- feign nations, and among the States., If it were a power it* prescribe those terms, it was a power to prescribe the whole terms. After Congress, in the exercise of its exclusive power, has préscribed certain terms, rt is incompetent for the States to add other terms. Could there be any doubt that the exclusive power of regulating, foreign commerce included that of prescribing to all the citizens of the Union ilie conditions, and the whole conditions, on. which they shall be permitted to bring into the 'United States, for sale or consúmption, the productions of foreign countries ? This power does not slop with the permission, to bring them in : for if the States may prohibit tlieir sale, or restrain, or bur-then it, in any mode, they may, in effect, prohibit their importation. If.they may prevent their sale, they may prohi bit their barter or exchauge,. or use and consumption in the country, in.any and every mode; ami thus effectually defeat the beneficial exercise of the permission to. import.. The States might even confiscate the goods, or order them to be burnt and destroyed after they were landed ; and this would no more interfere with the right of importation, according to the opposite argument, than the law' now in question. And, it was asked, whether the sagacious statesmen who framed the constitution meant to copier upon Congress a power so idle and illusory ’ They looked to the exercise of this power of regulating.commerce .as a great source of national wealth and aggrandizement. They looked to it as a great means' of developing the agricultural and manufacturing resources of the country, and its general industry as an instrument by which the nation should be enriched at home, and rendered capable of countervailing the commercial regulations of foreign and rival nations. But if. the power of regulating commerce ceases ón the landing of the goods, and the whole subject is then delivered'over to the discretion of the respective States, with their various partial and discordant views of policy, its exclusive exercise by Congress will be utterly vain and useless. So that the Very existence of that commerce, a power of regulating and preserving which is-so studiously conferred on Con gress, is at last made to depend upon the caprice and pleasure of the States. What signifies the power of regulation, if the States \may destroy the very substance of the thing to be regulated ? Uniformity, or permanency of regulation, with a view to any purpose of policy, in regárd to the agricultural, manufacturing, or commercial interests of the nation, is, of course, as much out of the question, as if there were, no Union, or as if it were still infected with all the debility of the former confederation. The same State power, exercised upon short sighted and narrow views, might be exerted so as to defeat the other branch of the power, that of regulating commerce among the States. The free intercommunication which now prevails between the States, may be effectually checked, by requiring asimilar license to import into a particular State the productions of other States. So, also, what the State may do as to imports, it may do as to exports. It may require a license from the exporting merchant, and thus, in effect, lay a duty on exports, although both the States and Congress are expressly forbidden in the constitution* from laying such a duty ; and the whole power of regulating the commerce, both of exports and imports, is exclusively vested in Congress. By the joint exercise of these two usurped powers, the State may establish a total non-intercourse with other States, and with foreign nations, in direct violation of the laws, and treaties, and constitution of the Union. Or it may make a discrimination among foreign nations, or among the different States, with a view of discouraging their commerce, or of encouraging some branch of its own internal industry, in direct repugnancy to the policy of the Union, as exhibited in its laws and treaties. One of the avowed objects for conferring the power of regulating commerce upon Congress, was that of raising a revenue for the support of the national government. It was foreseen, that the prosperity of commerce would best be promoted by uniform regulations contained in the laws and treaties of the Union; and it was also foreseen, that an impost was that species of taxation best suited to the genius and habits of the American people, But if the power now in question may be.exercised by one State, it may be exercised by all; and the principal source from which the revenues -of the Union were to bederived,wilfbe dried up, or diverted to local purposes.' In short, it was insisted, that all the evils for which the constitution was intended to provide an effectual remedy, would be entailed upon the country, by confirming the validity of such State laws as the act now in question.-

Opinion:
Mr. Chief Justice Marshall
delivered the opinión of the Court.
This is a writ of error to a judgment rendered in the Court of Appeals of Maryland, affirming a judgment of the City Court of Baltimore, on an indictment, found in that Court against the plaintiffs in error, for violating an act of the legislature of Maryland. The indictment was founded on the second section of that act, which is in these words : " And he it enacted, that all importers of foreign articles or commodities, of dry goods, wares, or merchandise, by bale or package, or of wine, rum, brandy, whiskey and other distilled spiritous liquors, &c. and other persons selling the same by wholesale, bale or package, hogshead, barrel, or tierce, shall, before they are authorized to sell, take out a license, as by the original act is directed, for which they shall pay fifty dollárs ; and in case of neglect or refusal to take out such license, shall be subject to the same penalties and forfeitures as are prescribed, by the original act to which this isa supplement." The indictment charges the plaimuTa hi error, with having imported and sold one package of foreign dry goods without haying license to do so. A judgment was rendered against them on demurrer for the penalty which the act prescribes for the offence; and that judgment is how before this Court.
The cause depends entirely on the question, whether the legislature of a State can constitutionally require the importer of foreign articles to take out a license from the State, before he shall be permitted to sell a bale or. package so imported.
It has h.een truly said, that the presumption is in favour of-every legislative act, and that the whole burthen of proof lies on him who denies its constitutionality. The plaintiffs m error take the burthen upon themselves, and insist that the act under consideration is repugnant to two provisions in the constitution of the United States.
Question as u, Jhe law',^resPect t0 *®e clause prom-the fay^gimpost? ?r duties on
1. To that which declares that " no State shall, without the consent of Congress, lay any imposts, or duties on imports or exports, except what may be absolutely necessary for.executing its inspection laws.".
2. To that which declares that Congress shall have power 1! to regulate commerce with foreign, nations, and among the several States, and with the Indian tribes."
1. The first inquiry is into the extent of the prohibition upon States "to lay any imposts or duties on imports or exports." The counsel for the State of Maryland would con- * t J fine this prohibition to laws imposing duties on the act importation or exportation. The counsel for the plaintiffs in error give them a much wider scope.
In performing the delicate and important duty of ing clauses in the .constitution of our country, which involve conflicting powers of the government of the Union, ahd of the respective States, it is proper to take a view of the literal meaning of.the words to be expounded, of their connexion with other words, and of the general objects to be accomplished by the prohibitory clause,' or by the grant of power.
What, then, is the meaning of the words, " imposts, or duties on ináports. or exports ?"
An impost, dr duty on imports, is a custom or a tax levied on articles brought into a country, and is most usually secured before .the importer is allowed to exercise his rights of ownership over them, because evasions of the law can be prevented more certainly by executing it while the articles are in its custody. It would not, however, be less an impost or duty on the articles, if it were to be levied on them after they were landed. The policy and consequent practice of levying or securing the duly before, or on entering the port; does not limit the power to that state of things, nor, consequently, the prohibition, unless the.true meaning of the clause so confines it. What,, then, are " imports ?" The lexicons inform us, they are " things imported." If we appeal to usage for the meaning of the word, we shall receive the same answer. They are the articles themselves, which are brought into the country " A duty on imports," then,- is not merely a duty on the act of importation, but is a duty on the thing imported. It is not, taken in its literal sense, confined to a duty levied while the article is entering-the country, but extends to a-duty- levied after it has entered the country. The succeeding words of the'sentence vthich limit the prohibition, show the extent in which it was understood. The limitation is, " except what may be absolutely necessary for executing its inspection laws." Now, the inspection laws, so far as they act upon articles for exportation, are generally executed on land, before the article is put on board the vessel ; so far as they act upon importations, they are generally executed upon articles which are landed. The tax or duty of inspection, then, is a tax which is frequently, if not always paid for service performed -on land, while the article is in the bosom of the country. Yet this tax is an exception to the prohibition on the States to lay duties on imports or exports. The exception was made because the tax would otherwise have been within the prohibition.
If it be a rule of interpretation to which all assent, that the exception of a particular thing from general words, proves that, in the opinion of the lawgiver, the thing excepted would be within the general clause had the exception r * been made, we know no reason why this general rule shook, not be as applicable to the constitution as to other instru-. ments. If it be applicable, then this exception in favour of duties for the supporrof inspection laws, goes far in proving that the framers of the constitution classed taxes of a similar character with those imposed for the purposes of inspection, with- duties on imports and. exports, and supposed them to be prohibited.
If we quit this narrow view of the subject, and passing from the literal interpretation pf the words, look to the objects of-1 the prohibition, we find no reason for withdrawing the act under consideration from its operation.
From the vast inequality between the different States of the confederacy, as to commercial advantages, few subjects . were viewed with deeper interest, or excitéd more irritation, than the manner in which the several States exercised,, or seemed disposed to exercise, the power of laying duties on -imports. From motives which were deemed sufficient by the statesmen of that day, the general power of taxation, indisp'ensably necessary as it was, and jealous as the Stateswere of any encroachment on it, was so far abridged as to forbad them to. touch imports or exports, with the single exception which .has' been noticed. Why are they restrained from imposing these duties ? Plainly, because, in the general opinion, the interest of all would be best promoted by placing that whole subject under the control of Congress. Whether the prohibition to " lay imposts, or duties on imports or exports," proceeded from an apprehension that the power might be so exercised as to disturb that equality among the States which was.generally advantageous, or that harmony between them which it. was desirable to preserve, or to maintain unimpaired our commercial connexions with foreign nations, or to confer this source of revenue on the government of the Union, or whatever other motive might have induced the prohibition, it is plain, that the object would be as completely defeated by a power to tax the article in the hands of the importer the instant it was landed, as by a power to tax it while entering the port. There is no difference, in effect, between a-power to prohibit the sale of an article, anda power to prohibit its introduction into the country. The one would be a necessary consequence of the other. No goods would be imported if none could be sold. No object of any description can be accomplished by laying a duty on importation, which may not be accomplished with equal certainty by laying a duty on the thing imported in the hands of the importer. It is obvious, that the same power which imposes a light duty, can impose a very heavy one, one which amounts to a prohibition; Questions of power do not depend on the degree to which it may be exercised. If it may be exercised at all, it must be exercised at the will of those in whose hands it is placed. If the tax may be levied in this form by a State, it may be levied to an extentWhich will defeat the revenue by impost, so far as it is drawn from importations into the particular State. W.e are told, that such wild and irrational abuse of power is not to be apprehended, and is not to be taken into view when discussing its existence. All power r,'.alabe abused; and if the fear of its abuse is to constitute amargument against its existence, it might be urged against the existence of'that, which is universally acknowledged, and which is indispensable to the general safety. The States will never be so mad as to destroy their own commerce,'or even to lessen it. We do not dissent.from these general propositions. We do not suppose any State would act so unwisely. JBut we do not place the question on that ground.
These arguments apply with precisely the same force against the whole prohibition. It-might, with the same reason be said, that no State would he so blind to its own interests as to lay duties on importation which would either prohibit or diminish its trade. Yet the framers of our constitution have thought this a power which no State ought to exercise. Conceding, to the full extent which is required, that every State would, in its legislation on this subject, providejudiciousiy for its own interests, it cannot be conceded, that each would respect the interests of others. A duty on imports is a tax on. the article which is paid by the consumer. The great importing States would thus levy a tax on the noni importing States, which would not be less a tax because- their interest would afford ample security against its-ever being .so heavy as'to expel commerce from their ports. This would necessarily .produce countervailing measures on the part of those States whose situation was less favourable to importation. For this, among other reasons, the whole power of laying duties on imports was, with a single and slight exception, taken from the States. When we are inquiring whether a particular act is within this prohibition, the question is not, whether the. State may so legislate as to Hurt itself, but whether the act is within the words and mischief of the prohibitory clause. It has already been shown, that a tax on the article in the hands of the importer, is within its words; and we think it too dear for controversy, that the same tax is within its mischief. We think it unquestionable, that such a tax has precisely the same tendency to enhance the price of the article, as if imposed •upon it y bile-entering .the port.
• The counsel for the State of Maryland insist, with great reason, that if the words of the prohibition be taken in their utmost latitude they will abridge the power of taxation- which all admit to be essential to the States, to an extent which has never yet been suspected, and will deprive them of resources which are necessary to supply revenue, and which they have heretofore been admitted to possess. These words must, therefore, be construed with some limitation; and, if this be admitted, they insist, that entering the country is the point of time when the prohibition ceases, and the power of the State to tax commences.
It may be conceded, that the words of the prohibition ought not to be pressed to their utmost extent; that in our complex system, the object of the powers conferred on the government of the Union, and the nature of the often conflicting powers which remain in the States, must always he taken into view, and may aid in expounding the words of any particular clause. But, while we admit that sound principles of construction ought to restrain all Courts from carrying the words of the prohibition beyond the object the constitution is intended to secure: that there must be a point of time when the prohibition ceases, and the power of the State to tax commences ; we cannot admit that this point of time is the instant that the articles enter the country. It is, we think, obvious, that this construction would defeat the prohibition.
The constitutional prohibition on the States to lay a duty on imports, a prohibition which a vast majority of them must feel an interest in preserving, may certainly come in conflict with their acknowledged power to tax persons and property within their territory. The power, and the restriction on it, though quite distinguishable when they do not approach each other, may yet, like the intervening co-lours between white and black, approach so nearly as to perplex>the understanding, as colours perplex the vision in marking the distinction between them. Yet the distinction exists, and must be marked as the cases arise. Till they do arise, it might be premature to state any rule as being universal in its application. It is sufficient for the present to say, generally, that when the importer has so acted upon the thing imported, that it has become- incorporated and mixed up with the mass of property in the country, it has*, perhaps, lost its distinctive character as an import, add has become subject to the taxing power of the State; but while remaining the property of the importer, in his warehouse, in the original form or- package in which it was imported, a tax upon it is too plainly a duty on imports to escape the prohibition in the constitution.
The counsel for the plaintiffs in error contend, that the importer purchases.' by payment of the duty to the United States, a right to dispose of his merchandise, as well as to bring it into the country; and certainly the argument is supported by strong reason, as well as by the practice of nations, including our own. The object of- importation is sale; it constitutes the motive for paying the duties ; and if the United States possess the power of conferring the right to sell, as the consideration for which the duty is paid, every principle of f3.ii' dealing requires that they should be understood to confer it. The practice of the most commercial nations conforms to this idea. Duties, according to that practice,. are charged on those articles only which are in--, tended for sale or consumption in the country. Thus, sea stores, goods imported and re-exported in the same vessel, goods landed and carried over land for the purpose of being re-exported from some other port, goods forced in by stress of weather, and landed, but not for sale, are exempted from the payment of duties. The whole course of legislation on the subject shows, that, in the opinion of the legislature, the right to sell is connected with the payment of duties.
-The counsel for the defendant in error have endeavoured to illustrate their proposition, that the constitutional prohibition ceases the instant the goods enter the country, by an array of the consequences which they suppose must follow the denial of it. If the importer acquires the right to sell by the payment of duties, he may, they say, exert that right when, where, and as he pleases, and the State cannot regu-. late it. He may sell by retail, at auction, or as an itinerant pedlar. He may introduce articles, as gunpowder, which endanger a city, into' the midst of its population ; he may introduce articles which endanger the public health, and -the power of self-preservation is denied. An importer may. bring in goods, as plate, for his own use, and thus retain much valuable property exempt from taxation.
These objections to the principle, if well founded, would certainly be entitled to serious consideration. But, we. think, they will be found, on examination, not to belong necessarily to the principle, and, consequently, not to prove, that it may pot be resorted to with safety as a criterion by which to measure the extent of the prohibition.
This indictment is against the importer, for selling a package of dry goods in the form in which it was imported, without a license. This state of things is changed if he sells . them, or otherwise mixes them with the general property of the State, by breaking up his packages, and travelling with them as an itinerant pedlar. In the first case, the tax intercepts the import, as am import, in its way to become incorporated with the general mass of property, and denies it the privilege of becoming so incorporated until it shall have contributed to the revenue of the State. It denies to the importer the right of using the privilege which he has purchased from the United States, until he shall have also purchased it from the State. In the last cases, the tax finds the article already incorporated with the mass of property by the act of the importer. He has used the privilege he had purchased, and has himself mixed them up with the common mass, and the law may treat them as it finds them. The same observations apply to plate, or other furniture used by the importer.
So, if he sells by auction. Auctioneers, asre persons, licensed by the State, and if the importer chooses to employ them, he can as little object to paying for this service, as for any other for. which he may apply to an officer of the State. The right of sale may very well, be annexed to importation, without annexing to it, also, the privilege of using the officers licensed by the State to'make sales in a peculiar way.
The power to direct the removal of gunpowder is a branch of the police power, which unquestionably remains, and ought to remain, with the States. If the possessor stores it himself out of town, the removal cannot be a duty ón imports, because it contributes nothing to the revenue. If be prefers placing it in a public magazine, it is because he stores it there, in his own opinion, more advantageously than else-1 where. We áre not sure that this may not be classed among inspection laws. The removal or destruction of infectious or unsound articles is, undoubtedly, an exercise of that power, and forms an express exception to the prohibition we are Considering. Indeed, the laws of the United States expressly sanction the health laws of a State.
The principle, then,' for which the plaintiffs in error contend, that the importer acquires a right, not only to bring, the articles into the country, but to mix them with the common mass of property, does not interfere with the necessary power of taxation which is acknowledged to reside in the States, to that dangerous extent which the counsel for the defendants in error seem to apprehend. It carries thé prohibition in the constitution no farther than to prevent the States from doing that which it was the great object of the constitution to prevent.
But if it should be proved, that a duty on the article itself would be repugnant to the constitution, it is still argued, that this is not a tax upon the article, but on the person. jThe State, it is said, may tax occupations, and this is nothing more.
It is.impossible to conceal from ourselves, that this is varying the form, without varying the substance. It is treat-i'óg a prohibition which is general, as if it were confined .to a particular mode of dojng the forbidden thing. All must perceive, that a tax on the sale of an article, imported only for sale, is a tax on the article itself. It is true, the State may tax occupations generally, but this tax must be paid by those who employ the individual, or is a tax on his business. The lawyer, the physician, or the mechanic, must either charge more on the article in which he deals, or the thing itself is taxed through his person. This the State has a right to do, because no constitutional prohibition extends to it. So, a tax on the occupation of ah importer is, in like manner, a tax on importation. It must add to the price of the article, and be paid by the consumer, or by the importer himself, in like manner as a direct duty on the article itself would be made. This the State has not a right to do, because it is prohibited by the constitution.
Question as to Jeauiating* commerce-.
In support of the argument, that the prohibition ceases the instant the goods are brought into the country, a compa- . rison has been drawn between the opposite words export and import. As," to export, it is said, means only to carry goods out of the country; so, to import, means only to bring them into it. But, suppose we extend this comparison to the two prohibitions. The States are forbidden to lay a duty on exports, and the United States are forbidden, to lay a tax or duty on articles exported from any State There is some diversity in language, but none is perceivable in the act which is prohibited. The United States have the same right to tax occupations which is possessed by the States. Now, suppose the United States-should require every exporter to take out a license, for which he should pay shch tax as Congress might think proper to impose ; would government be permitted to shield itself from the just censure to. which this attempt to evade the prohibitions of the constitution would expose it, by saying, that this was a tax on the person, not on the article, and that the legislature had a right to-tax occupations ? Or, suppose revenue cutters were to be stationed off the coast for the purpose of levying a duty on all merchandise found in vessels which were leaving the United States for foreign countries ; would it be received as an excuse for this , outrage, were the government to sayr that exportation meant no more than carrying goods out of the country, and as the prohibition to lay a tax on imports, or things imported, ceased the instant they were brought into the country, so the prohibition to tax articles exported ceased when they were carried out of the country ?
We'think, then, that the act under which the plaintiffs in error were indicted, is repugnant to that article of the constitution which declares, that " no State shall lay any impost or duties on imports or exports."
2. Is it also repugnant to that clause in the constitution which empowers " Congress to regulate commerce with foreign nations, and among the several States, and with the Indian tribes?"
The oppressed and degraded state of commerce previous to the adoption of the constitution can scarcely be forgotten. It was regulated by foreign nations .with a single view to their own interests.; and our disunited efforts to counteract their restrictions were rendered impotent by want of combination. Congress, indeed, possessed the power of making treaties; but the inability of the federal government to enforce them had become so appárent as to render that power in a great degree useless. Those who felt the injury arising from this state of things, and those who were capable of estimating the influence of commerce on the prosperity of nations, perceived the necessity of giving the control over this important subject to a single government. It may be doubted whether any of the evils proceeding from the feebleness of the federal government, contributed more to that' great revolution which introduced the present system, than the deep and general conviction, that commerce ought to be regulated by Congress. It is not, therefore,' matter of surprise, that the grant should be as extensive as the mischief, and should comprehend all foreign commerce, and all c >mmerce among the States. To construe the power so as to impair its efficacy, would tend to defeat an object, in the attainment of which the American public took, and justly took, that strong interest which arose from a full conviction of its necessity.
What, then, is the just extent of a power to regulate commerce with foreign nations, and among the several States?
This question was considered in the case of Gibbons v. Ogden, (9 Wheat. Rep. 1.) in which it was declared to be complete in itself, and to acknowledge no limitations other •than are prescribed by the constitution. The power is coextensive with the subject on which it acts, and cannot be stopped at the external boundary of a State, but must enter its interior.
Wé deem it unnecessary now to reason in support of these propositions. Their truth is proved, by facts continually before our eyes, and was, we think, demonstrated, if they could require demonstration, in the case already mentioned,
If this power reaches the interior of. a Stale, and may be there exercised, it must be capable of authorizing the sale of those articles which it introduces. Commerce is inter course : one of its most ordinary ingredients is traffic. Iris inconceivable, that the power to authorize this traffic, when given in the most comprehensive terms, with the intent that its efficacy should be complete, should cease at the point when its continuance is indispeusable-to its value. To what purpose should the power to allow importation be given, unaccompanied with the power to authorize a sale of the thing imported ? Sale is the object of importation, and is an essential ingredient of that intercourse, of which importation constitutes a. part. It is as essential an ingredient, as indispensable to the existence of the entire thing, then, as importation itself. It must be considered as a component part of the power to regulate commerce. Congress has a right, not only to authorize importation, but to authorize the importer to sell.
If this be admitted, and we think it cannot be denied, what can the meaning of an act of Congress which authorizes importation, and offers the privilege for sale at a fixed price to every person who chooses to become a purchaser ? How is it to be construed, if an intent to deal honestly and fairly, an intent as wise as it is moral, is to enter into the construction ? What can be the use of the contract, what does the importer purchase, if he does not purchase the privilege to sell ?
What would be the language of a foreign government, which should be informed that its merchants, after importing according to law, were forbidden to sell the' merchandise imported ? What answer would the United States give to the complaints and just reproaches to which such an extraordinary circumstance would expose them ? Ni apology could be received, or even offered. Such a state of things would break up commerce, it will not meet this argument, to say, that this state of things will never be produced; that the good sense of the States is a sufficient security against if The constitution has not confided this subject to that good sense. It is placed elsewhere. The question is, where does the power reside ? not, how far will it be probably abused" The power claimed by the State is, in its nature, in conflict with that given to Congress; and the greater or less extent in which it may be exercised does not enter into (he inquiry concerning its existence.
We think, then, that if the power to authorize a sale exists in Congress, the conclusion that the rigfit to sell is connect-e(j wjth the law permitting importation, as an inseparable incident, is inevitable.
Jf the principles we have stated be correct, the result to which they conduct us cannot be mistaken- Any penalty inflicted on the importer for selling the article in his character of importer, must be in opposition to the act of Congress which authorizes importation. Any charge on the introduction and incorporation of the articles into and with the mass of property in the country, must be hostile to the power given to Congress to regulate commerce, since an essential part.of that regulation, and principal object of it, is to prescribe the regular means for accomplishing that introduction and incorporaron.
The distinction between a tax on the thing imported, and on the person of the importer, can have no influence on this part of the subject. It is loo obvious for controversy, that they interfere equally with'the power to regulate commerce.
It has been contended, that this construction of the power to regulate commerce, as was contended in construing the prohibition-to Jay duties on imports, would abridge the acknowledged power of a State to tax its owrn citizens, or their property, within its territory.
We admit this power to be sacred; but cannot admit that it may be used so as to obstruct the free course of a power given to Congress. We cannot admit, that it may be used so as to obstruct or defeat the power to regulate commerce. It has beeri observed, that the powers remaining with the States may be so exercised as to come in conflict with those vested in Congress. When this happens, that which is not supreme must yield to that which is supreme, This great and universal truth is inseparable from the nature of things, and the constitution has applied it to the often interfering powers of the general and State governments, as a vital principle of perpetual operation.' It results, necessarily, from this principle, that the taxing power of the States must have some limits. It cannot reach and restrain the action of the national government within its proper sphere, It cannot reach the administration of
justice m the Courts of the. Union, or the collection ol the taxes of the United States, or restrain the-operation'of any law which Congress may constitutionally pftss. It cannot interfere with any regulation of commerce. If the States may tax all persons and property found on their territory, what shall restrain them from taxing goods in their transit through the State from one port to another, for the purpose of re-exportation'? The laws of trade authorize this ope-ration, and general convenience requires it. Or what should restrain a State from taxing any article passing through it from one State to another, for the purpose of traffic ? or from taxing the transportation of articles passing from the State itself to another State, for commercial pur-: poses ? These cases are all within the sovereign power of taxation, but would obviously derange the measures of Congress to regulate commerce, and affect materially the purpose for which that ppwer was given. Wo deem it unnecessary to press this argument farther, or to give additional illustrations of it, because the subject was taken up, and .considered with great attention, in M'Culloch, v. The State of Maryland, (4 Wheat. Rep. 316.) the decision in which casé is, we think, entirely applicable to this.
It may be proper to add, that we suppose the principles laid down in this case, to apply equally to importations from a sister State. We do not mean to give any opinion on a tax discriminating between foreign and domestic articles.
We think there is error in the judgment of the Court of Appeals of the State of Maryland, in affirming the judgment of the Baltimore City Court, because the act of the legislature of Maryland, imposing the penalty for which the said judgment is rendered, is repugnant to the constitution of the United States, and, consequently, void. The judgment'is to be reversed, and the cause remanded to that Court, with instructions to enter judgment in favour of the appellants.
