McCulloch v. Maryland (1819) (Excerpts)

Opinion of the Court by John Marshall

The first question made in the cause is, has Congress power to incorporate a bank?

[Historical unwritten constitution argument]

It has been truly said, that this can scarcely be considered as an open question, entirely unprejudiced by the former proceedings of the nation respecting it. The principle now contested was introduced at a very early period of our history, has been recognized by many successive legislatures, and has been acted upon by the judicial department, in cases of peculiar delicacy, as a law of undoubted obligation.

It will not be denied, that a bold and daring usurpation might be resisted, after an acquiescence still longer and more complete than this. But it is conceived that a doubtful question, one on which human reason may pause, and the human judgment be suspended, in the decision of which the great principles of liberty are not concerned, but the respective powers of those who are equally the representatives of the people, are to be adjusted; if not put at rest by the practice of the government, ought to receive a considerable impression from that practice. An exposition of the constitution, deliberately established by legislative acts, on the faith of which an immense property has been advanced, ought not to be lightly disregarded.

The power now contested was exercised by the first Congress elected under the present constitution.  The bill for incorporating the bank of the United States did not steal upon an unsuspecting legislature, and pass unobserved. Its principle was completely understood, and was opposed with equal zeal and ability. After being resisted, first in the fair and open field of debate, and afterwards in the executive cabinet, with as much persevering talent as any measure has ever experienced, and being supported by arguments which convinced minds as pure and as intelligent as this country can boast, it became a law. The original act was permitted to expire; but a short experience of the embarrassments to which the refusal to revive it exposed the government, convinced those who were most prejudiced against the measure of its necessity, and induced the passage of the present law. It would require no ordinary share of intrepidity to assert that a measure adopted under these circumstances was a bold  and plain usurpation, to which the constitution gave no countenance.

These observations belong to the cause; but they are not made under the impression that, were the question entirely new, the law would be found irreconcilable with the constitution.

[People of the States or People of the Nation]

In discussing this question, the counsel for the State of Maryland have deemed it of some importance, in the construction of the constitution, to consider that instrument not as emanating from the people, but as the act of sovereign and independent States. The powers of the general government, it has been said, are delegated by the States, who alone are truly sovereign; and must be exercised in subordination to the States, who alone possess supreme dominion.

It would be difficult to sustain this proposition. The Convention which framed the constitution was indeed elected by the State legislatures. But the instrument, when it came from their hands, was a mere proposal, without obligation, or pretensions to it. It was reported to the then existing Congress of the United States, with a request that it might "be submitted to a Convention of Delegates, chosen in each State by the people thereof, under the recommendation of its Legislature, for their assent and ratification." This mode of proceeding was adopted; and by the Convention, by Congress, and by the State Legislatures, the instrument was submitted to the people. They acted upon it in the only manner in which they can act safely, effectively, and wisely, on such a subject, by assembling in Convention. It is true, they assembled in their several States--and where else should they have assembled? No political dreamer was ever wild enough to think of breaking down the lines which separate the States, and of compounding the American people into one common mass. Of consequence, when they act, they act in their States. But the measures they adopt do not, on that account, cease to be the measures of the people themselves, or become the measures of the State governments.

From these Conventions the constitution derives its whole authority. The government proceeds directly from the people; is "ordained and established" in the name of the people; and is declared to be ordained, "in order to form a more perfect union, establish justice, ensure domestic tranquility, and secure the blessings of liberty to themselves and to  their posterity." The assent of the States, in their sovereign capacity, is implied in calling a Convention, and thus submitting that instrument to the people. But the people were at perfect liberty to accept or reject it; and their act was final. It required not the affirmance, and could not be negatived, by the State governments. The constitution, when thus adopted, was of complete obligation, and bound the State sovereignties.

It has been said, that the people had already surrendered all their powers to the State sovereignties, and had nothing more to give. But, surely, the question whether they may resume and modify the powers granted to government does not remain to be settled in this country. Much more might the legitimacy of the general government be doubted, had it been created by the States. The powers delegated to the State sovereignties were to be exercised by themselves, not by a distinct and independent sovereignty, created by themselves. To the formation of a league, such as was the confederation, the State sovereignties were certainly competent. But when, "in order to form a more perfect union," it was deemed necessary to change this alliance into an effective government, possessing great and sovereign powers, and acting directly on the people, the necessity of referring it to the people, and of deriving its powers directly from them, was felt and acknowledged by all.

The government of the Union, then, (whatever may be the influence of this fact on the case,) is, emphatically, and truly, a government of the people. In form and in substance it emanates from them. Its powers are granted by them, and are to be exercised directly on them, and for their benefit.

This government is acknowledged by all to be one of enumerated powers. The principle, that it can exercise only the powers granted to it, would seem too apparent to have required to be enforced by all those arguments which it enlightened friends, while it was depending before the people, found it necessary to urge. That principle is now universally admitted. But the question respecting the extent of the powers actually granted, is perpetually arising, and will probably continue to arise, as long as our system shall exist.

In discussing these questions, the conflicting powers of the general and State governments must be brought into view, and the supremacy of their respective laws, when they are in opposition, must be settled.

If any one proposition could command the universal assent of mankind, we might expect it would be this -- that the government of the Union, though limited in its powers, is supreme within its sphere of action. This would seem to result necessarily from its nature. It is the government of all; its powers are delegated by all; it represents all, and acts for all. Though any one State may be willing to control its operations, no State is willing to allow others to control them. The nation, on those subjects on which it can act, must necessarily bind its component parts. But this question is not left to mere reason: the people have, in express terms, decided it, by saying,  "this constitution, and the laws of the United States, which shall be made in pursuance thereof," "shall be the supreme law of the land," and by requiring that the members of the State legislatures, and the officers of the executive and judicial departments of the States, shall take the oath of fidelity to it.

The government of the United States, then, though limited in its powers, is supreme; and its laws, when made in pursuance of the constitution, form the supreme law of the land, "any thing in the constitution or laws of any State to the contrary notwithstanding."

Among the enumerated powers, we do not find that of establishing a bank or creating a corporation. But there is no phrase in the instrument which, like the articles of confederation, excludes incidental or implied powers; and which requires that every thing granted shall be expressly and minutely described. Even the 10th amendment, which was framed for the purpose of quieting the excessive jealousies which had been excited, omits the word "expressly," and declares only that the powers "not delegated to the United States, nor prohibited to the States, are reserved to the States or to the people;" thus leaving the question, whether the particular power which may become the subject of contest has been delegated to the one government, or prohibited to the other, to depend on a fair construction of the whole instrument. The men who drew and adopted this amendment had experienced the embarrassments resulting from the insertion of this word in the articles of confederation, and probably omitted it to avoid those embarrassments. A constitution, to contain an accurate detail of all the subdivisions of which its great powers will admit, and of all the means by which they may be carried into execution, would partake of the prolixity of a legal code, and could scarcely be embraced by the human mind. It would probably never be understood by the public. Its nature, therefore, requires, that only its great outlines should be marked, its important objects designated, and the minor ingredients which compose those objects be deduced from the nature of the objects themselves. That this idea was entertained by the framers of the American constitution, is not only to be inferred from the nature of the instrument, but from the language. Why else were some of the limitations, found in the ninth section of the 1st article, introduced? It is also, in some degree, warranted by their having omitted to use any restrictive term which might prevent its receiving a fair and just interpretation. In considering this question, then, we must never forget, that it is a constitution we are expounding.

Although, among the enumerated powers of government, we do not find the word "bank" or "incorporation," we find the great powers to lay and collect taxes; to borrow money; to regulate commerce; to declare and conduct a war; and to raise and support armies and navies. The sword and the purse, all the external relations, and no inconsiderable portion of the industry of the nation, are entrusted to its government. It can never be pretended   that these vast powers draw after them others of inferior importance, merely because they are inferior. Such an idea can never be advanced. But it may with great reason be contended, that a government, entrusted with such ample powers, on the due execution of which the happiness and prosperity of the nation so vitally depends, must also be entrusted with ample means for their execution. The power being given, it is the interest of the nation to facilitate its execution. It can never be their interest, and cannot be presumed to have been their intention, to clog and embarrass its execution by withholding the most appropriate means. Throughout this vast republic, from the St. Croix to the Gulf of Mexico, from the Atlantic to the Pacific, revenue is to be collected and expended, armies are to be marched and supported. The exigencies of the nation may require that the treasure raised in the north should be transported to the south, that raised in the east conveyed to the west, or that this order should be reversed. Is that construction of the constitution to be preferred which would render these operations difficult, hazardous, and expensive? Can we adopt that construction, (unless the words imperiously require it,) which would impute to the framers of that instrument, when granting these powers for the public good, the intention of impeding their exercise by withholding a choice of means? If, indeed, such be the mandate of the constitution, we have only to obey; but that instrument does not profess to enumerate the means by which the powers it confers may be executed; nor does it prohibit the creation of a corporation, if the existence of such a being be essential to the beneficial exercise of those powers. It is, then, the subject of fair inquiry, how far such means may be employed….

It is … denied that the government has its choice of means; or, that it may employ the most convenient means, if, to employ them, it be necessary to erect a corporation.

The government which has a right to do an act, and has imposed on it the duty of performing that act, must, according to the dictates of reason, be allowed to select the means; and those who contend that it may not select any appropriate means, that one particular mode of effecting the object is excepted, take upon themselves the burden of establishing that exception.

The creation of a corporation, it is said, appertains to sovereignty. This is admitted. But to what portion of sovereignty does it appertain? Does it belong to one more than to another? In America, the powers of sovereignty are divided between the government of the Union, and those of the States. They are each sovereign, with respect to the objects committed to it, and neither sovereign with respect to the objects committed to the other.

The power of creating a corporation, though appertaining to sovereignty, is not, like the power of making war, or levying taxes, or of regulating commerce, a great substantive and independent power, which cannot be implied as incidental to other powers, or used as a means of executing them. It is never the end for which other powers are exercised, but a means by which other objects are accomplished. No contributions are made to charity for the sake of an incorporation, but a corporation is created to administer the charity; no seminary of learning is instituted in order to be incorporated, but the corporate character is conferred to subserve the purposes of education. No city was ever built with the sole object of being incorporated, but is incorporated as affording the best means of being well governed. The power of creating a corporation is never used for its own sake, but for the purpose of effecting something else. No sufficient reason is, therefore, perceived, why it may not pass as incidental to those powers which are expressly given, if it be a direct mode of executing them.

[Necessary and Proper Clause]

[T]he constitution of the United States has not left the right of Congress to employ the necessary means, for the execution of the powers conferred on the government, to general reasoning. To its enumeration of powers is added that of making "all laws which shall 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 thereof."

The counsel for the State of Maryland have urged various arguments, to prove that this clause, though in terms a grant of power, is not so in effect; but is really restrictive of the general right, which might otherwise be implied, of selecting means for executing the enumerated powers.

In support of this proposition, they have found it necessary to contend, that this clause was inserted for the purpose of conferring on Congress the power of making laws. That, without it, doubts might be entertained, whether Congress could exercise its powers in the form of legislation.

[T]he argument on which most reliance is placed, is drawn from the peculiar language of this clause. Congress is not empowered by it to make all laws, which may have relation to the powers conferred on the government, but such only as may be "necessary and proper" for carrying them into execution. The word "necessary," is considered as controlling the whole sentence, and as limiting the right to pass laws for the execution of the granted powers, to such as are indispensable, and without which the power would be nugatory. That it excludes the choice of means, and leaves to Congress, in each case, that only which is most direct and simple.

Is it true, that this is the sense in which the word "necessary" is always used? Does it always import an absolute physical necessity, so strong, that one an absolute physical necessity, so strong, that one thing, to which another may be termed necessary, cannot exist without that other? We think it does not. If reference be had to its use, in the common affairs of the world, or in approved authors, we find that it frequently imports no more than that one thing is convenient, or useful, or essential to another. To employ the means necessary to an end, is generally understood as employing any means calculated to produce the end, and not as being confined to those single means, without which the end would be entirely unattainable.

The subject is the execution of those great powers on which the welfare of a nation essentially depends. It must have been the intention of those who gave these powers, to insure, as far as human prudence could insure, their beneficial execution. This could not be done by confiding the choice of means to such narrow limits as not to leave it in the power of Congress to adopt any which might be appropriate, and which were conducive to the end. This provision is made in a constitution intended to endure for ages to come, and, consequently, to be adapted to the various crises of human affairs. To have prescribed the means by which government should, in all future time, execute its powers, would have been to change, entirely, the character of the instrument, and give it the properties of a legal code. It would have been an unwise attempt to provide, by immutable rules, for exigencies which, if foreseen at all, must have been seen dimly, and which can be best provided for as they occur. To have declared that the best means shall not be used, but those alone without which the power given would be nugatory, would have been to deprive the legislature of the capacity to avail itself of experience, to exercise its reason, and to accommodate its legislation to circumstances. If we apply this principle of construction to any of the powers of the government, we shall find it so pernicious in its operation that we shall be compelled to discard it.

The result of the most careful and attentive consideration bestowed upon this clause is, that if it does not enlarge, it cannot be construed to restrain the powers of Congress, or to impair the right of the legislature to exercise its best judgment in the selection of measures to carry into execution the constitutional powers of the government. If no other motive for its insertion can be suggested, a sufficient one is found in the desire to remove all doubts respecting the right to legislate on that vast mass of incidental powers which must be involved in the constitution, if that instrument be not a splendid bauble.

We admit, as all must admit, that the powers of the government are limited, and that its limits are not to be transcended. But we think the sound construction of the constitution must allow to the national legislature that discretion, with respect to the means by which the powers it confers are to be carried into execution, which will enable that body to perform the high duties assigned to it, in the manner most beneficial to the people. Let the end be legitimate, let it be within the scope of the constitution, and all means which are appropriate, which are plainly adapted to that end, which are not prohibited, but consist with the letter and spirit of the constitution, are constitutional.

That a corporation must be considered as a means not less usual, not of higher dignity, not more requiring a particular specification than other means, has been sufficiently proved. If we look to the origin of corporations, to the manner in which they have been framed in that government from which we have derived most of our legal principles and ideas, or to the uses to which they have been applied, we find no reason to suppose that a constitution, omitting, and wisely omitting, to enumerate all the means for carrying into execution the great powers vested in government, ought to have specified this. Had it been intended to grant this power as one which should be distinct and independent, to be exercised in any case whatever, it would have found a place among the enumerated powers of the government. But being considered merely as a means, to be employed only for the purpose of carrying into execution the given powers, there could be no motive for particularly mentioning it.

If a corporation may be employed indiscriminately with other means to carry into execution the powers of the government, no particular reason can be assigned for excluding the  use of a bank, if required for its fiscal operations. To use one, must be within the discretion of Congress, if it be an appropriate mode of executing the powers of government. That it is a convenient, a useful, and essential instrument in the prosecution of its fiscal operations, is not now a subject of controversy. All those who have been concerned in the administration of our finances, have concurred in representing its importance and necessity; and so strongly have they been felt, that statesmen of the first class, whose previous opinions against it had been confirmed by every circumstance which can fix the human judgment, have yielded those opinions to the exigencies of the nation.

Should Congress, in the execution of its powers, adopt measures which are prohibited by the constitution; or should Congress, under the pretext of executing its powers, pass laws for the accomplishment of objects not entrusted to the government; it would become the painful duty of this tribunal, should a case requiring such a decision come before it, to say that such an act was not the law of the land. But where the law is not prohibited, and is really calculated to effect any of the objects entrusted to the government, to undertake here to inquire into the degree of its necessity, would be to pass the line which circumscribes the judicial department, and to tread on legislative ground. This court disclaims all pretensions to such a power.

After this declaration, it can scarcely be necessary to say, that the existence of State banks can have no possible influence on the question. No trace is to be found in the constitution of an intention to create a dependence of the government of the Union on those of the States, for the execution of the great powers assigned to it. Its means are adequate to its ends; and on those means alone was it expected to rely for the accomplishment of its ends. To impose on it the necessity of resorting to means which it cannot control, which another government may furnish or withhold, would render its course precarious, the result of its measures uncertain, and create a dependence on other governments, which might disappoint its most important design, and is incompatible with the language of the constitution. But were it otherwise, the choice of means implies a right to choose a national bank in preference to State banks, and Congress alone can make the election.

After the most deliberate consideration, it is the unanimous and decided opinion of this Court, that the act to incorporate the Bank of the United States is a law made in pursuance of the constitution, and is a part of the supreme law of the land.

It being the opinion of the Court, that the act incorporating the bank is constitutional; and that the power of establishing a branch in the State of Maryland might be properly exercised by the bank itself, we proceed to inquire --

2. Whether the State of Maryland may, without violating the constitution, tax that branch?

That the power of taxation is one of vital importance; that it is retained by the States; that it is not abridged by the grant of a similar power to the government of the Union; that it is to be concurrently exercised by the two governments: are truths which have never been denied.

This great principle is, that the constitution and the laws made in pursuance thereof are supreme; that they control the constitution and laws of the respective States, and cannot be controlled by them. From this, which may be almost termed an axiom, other propositions are deduced as corollaries, on the truth or error of which, and on their application to this case, the cause has been supposed to depend. These are, 1st. that a power to create implies a power to preserve. 2nd. That a power to destroy, if wielded by a different hand, is hostile to, and incompatible with these powers to create and to preserve. 3d. That where this repugnancy exists, that authority which is supreme must control, not yield to that over which it is supreme.

The power of Congress to create, and of course to continue, the bank, was the subject of the preceding part of this opinion; and is no longer to be considered as questionable.

That the power of taxing it by the States may be exercised so as to destroy it, is too obvious to be denied. 

The argument on the part of the State of Maryland, is, not that the States may directly resist a law of Congress, but that they may exercise their  acknowledged powers upon it, and that the constitution leaves them this right in the confidence that they will not abuse it.

Before we proceed to examine this argument, and to subject it to the test of the constitution, we must be permitted to bestow a few considerations on the nature and extent of this original right of taxation, which is acknowledged to remain with the States. It is admitted that the power of taxing the people and their property is essential to the very existence of government, and may be legitimately exercised on the objects to which it is applicable, to the utmost extent to which the government may choose to carry it. The only security against the abuse of this power, is found in the structure of the government itself. In imposing a tax the legislature acts upon its constituents. This is in general a sufficient security against erroneous and oppressive taxation.

The people of a State, therefore, give to their government a right of taxing themselves and their property, and as the exigencies of government cannot be limited, they prescribe no limits to the exercise of this right, resting confidently on the interest of the legislator, and on the influence of the constituents over their representative, to guard then against its abuse. But the means employed by the government of the Union have no such security, nor is the right of a State to tax them sustained by the same theory. Those means are not given by the people of a particular State, not given by the constituents of the legislature, which claim the right to tax them, but by the people of all the States. They are given by all, for the benefit of all -- and upon theory, should be subjected to that government only which belongs to all.

It may be objected to this definition, that the power of taxation is not confined to the people and property of a State. It may be exercised upon every object brought within its jurisdiction.

This is true. But to what source do we trace this right? It is obvious, that it is an incident of sovereignty, and is co-extensive with that to which it is an incident. All subjects over which the sovereign power of a State extends, are objects of taxation; but those over which it does not extend, are, upon the soundest principles, exempt from taxation. This  proposition may almost be pronounced self-evident.

The sovereignty of a State extends to everything which exists by its own authority, or is introduced by its permission; but does it extend to those means which are employed by Congress to carry into execution powers conferred on that body by the people of the United States? We think it demonstrable that it does not. Those powers are not given by the people of a single State. They are given by the people of the United States, to a government whose laws, made in pursuance of the constitution, are declared to be supreme. Consequently, the people of a single State cannot confer a sovereignty which will extend over them.

If we measure the power of taxation residing in a State, by the extent of sovereignty which the people of a single State possess, and can confer on its government, we have an intelligible standard, applicable to every case to which the power may be applied. We have a principle which leaves the power of taxing the people and property of a State unimpaired; which leaves to a State the command of all its resources, and which places beyond its reach, all those powers which are conferred by the people of the United States on the government of the Union, and all those means which are given for the purpose of carrying those powers into execution. We have a principle which is safe for the States, and safe for the Union. We are relieved, as we ought to be, from clashing sovereignty; from interfering powers; from a repugnancy between a right in one government to pull down what there is an acknowledged right in another to build up; from the incompatibility of a right in one government to destroy what there is a right in another to preserve. We are not driven to the perplexing inquiry, so unfit for the judicial department, what degree of taxation is the legitimate use, and what degree may amount to the abuse of the power. The attempt to use it one the means employed by the government of the Union, in pursuance of the constitution, is itself an abuse, because it is the usurpation of a power which the people of a single State cannot give.

That the power to tax involves the power to destroy; that the power to destroy may defeat and render useless the power to create; that there is a plain repugnance, in conferring on one government a power to control the constitutional measures of another, which other, with respect to those very measures, is declared to be supreme over that which exerts the control, are propositions not to be denied. But all inconsistencies are to be reconciled by the magic of the word CONFIDENCE. Taxation, it is said, does not necessarily and unavoidably destroy. To carry it to the excess of destruction would be an abuse, to presume which, would banish that confidence which is essential to all government.

But is this a case of confidence? Would the people of any one State trust those of another with a power to control the most insignificant operations of their State government? We know they would not. Why, then, should we suppose that the people of any one State should be willing to trust those of another with a power to control the operations of a government to which they have confided their most important and most valuable interests? In the legislature of the Union alone, are all represented. The legislature of the Union alone, therefore, can be trusted by the people with the power of controlling measures which concern all, in the confidence that it will not be abused. This, then, is not a case of confidence, and we must consider it as it really is.

If we apply the principle for which the State of Maryland contends, to the constitution generally, we shall find it capable of changing totally the character of that instrument. We shall find it capable of arresting all the measures of the government, and of prostrating it at the foot of the States. The American people have declared their constitution, and the laws made in pursuance thereof, to be supreme; but this principle would transfer the supremacy, in fact, to the States.

If the States may tax one instrument, employed by the government in the execution of its powers, they may tax any and every other instrument. They may tax the mail; they may tax the mint; they may tax patent rights; they may tax the papers of the custom-house; they may tax judicial process; they may tax all the means employed by the government, to an excess which would defeat all the ends of government. This was not intended by the American people. They did not design to make their government dependent on the States.

Gentlemen say, they do not claim the right to extend State taxation to these objects. They limit their pretensions to property. But on what principle is this distinction made? Those who make it have furnished no reason for it, and the principle for which they contend denies it. They contend that the power of taxation has no other limit than is found in the 10th section of the 1st article of the constitution; that, with respect to every thing else, the power of the States is supreme, and admits of no control. If this be true, the distinction between property and other subjects to which the power of taxation is applicable, is merely arbitrary, and can never be sustained. This is not all. If the controlling power of the States be established; if their supremacy as to taxation be acknowledged; what is to restrain their exercising this control in any shape they may please to give it? Their sovereignty is not confined to taxation. That is not the only mode in which it might be displayed. The question is, in truth, a question of supremacy; and if the right of the States to tax the means employed by the general government be conceded, the declaration that the constitution, and the laws made in pursuance thereof, shall be the supreme law of the land, is empty and unmeaning declamation.

 It has also been insisted, that, as the power of taxation in the general and State governments is acknowledged to be concurrent, every argument which would sustain the right of the general government to tax banks chartered by the States, will equally sustain the right of the States to tax banks chartered by the general government.

But the two cases are not on the same reason. The people of all the States have created the general government, and have conferred upon it the general power of taxation. The people of all the States, and the States themselves, are represented in Congress, and, by their representatives, exercise this power. When they tax the chartered institutions of the States, they tax their constituents; and these taxes must be uniform. But, when a State taxes the operations of the government of the United States, it acts upon institutions created, not by their own constituents, but by people over whom they claim no control. It acts upon the measures of a government created by others as well as themselves, for the benefit of others in common with themselves. The difference is that which always exists, and always must exist, between the action of the whole on a part, and the action of a part on the whole -- between the laws of a government declared to be supreme, and those of a government which, when in opposition to those laws, is not supreme.

The Court has bestowed on this subject its most deliberate consideration. The result is a conviction that the States have no power, by taxation or otherwise, to retard, impede, burden, or in any manner control, the operations of the constitutional laws enacted by Congress to carry into execution the powers vested in the general government. This is, we think, the unavoidable consequence of that supremacy which the constitution has declared.

We are unanimously of opinion, that the law passed by the legislature of Maryland, imposing a tax on the Bank of the United States, is unconstitutional and void.

This opinion does not deprive the States of any resources which they originally possessed. It does not extend to a tax paid by the real property of the bank, in common with the other real property within the State, nor to a tax imposed on the interest which the citizens of Maryland may hold in this institution, in common with other property of the same description throughout the State. But this is a tax on the operations of the bank, and is, consequently, a tax on the operation of an instrument employed by the government of the Union to carry its powers into execution. Such a tax must be unconstitutional.
