Mr. Justice Black
delivered the opinion of the Court.
This is the third in a series of cases from the State of Michigan decided today involving a claim of constitutional tax immunity.
In 1952 Murray Corporation was acting as a subcontractor under a prime contract for the manufacture of airplane parts between two other private companies and the United States. From time to time Murray received partial payments from the two prime contractors as it performed its obligations under the subcontract. By agreement, title to all parts, materials and work in process acquired by Murray in performance of the subcontract vested in the United States upon any such partial payment, even though Murray retained possession.
On January 1,1952, the City of Detroit and the County of Wayne, Michigan, each assessed a tax against Murray which in part was based on the value of materials and work in process in its possession to which the United States held legal title under the title-vesting provisions of the subcontract. Murray paid this part of each tax under protest and then sued in a Federal District Court for a refund from the city and county. It contended that full title to the property was in the United States and that the taxes infringed the Federal Government’s immunity from state taxation to the extent they were based on such property. The Government intervened on Murray’s behalf. On motion for summary judgment the District Court entered judgment for Murray and the Court of Appeals for the Sixth Circuit affirmed. 234 F. 2d 380. From this decision the city and county both appealed and petitioned for certiorari. We granted certiorari and postponed the question of jurisdiction on appeal to the hearing on the merits. 352 U. S. 960, 963. The appeal was proper. 28 U. S. C. § 1254 (2).
We believe that this case is also controlled by the principles expressed in our opinions in Nos. 26 and 37, ante, pp. 466, 484, and that the taxes challenged here do not violate the Constitution. These taxes were not levied directly against the United States or its property. To the contrary they were imposed on'Murray, a private corporation, and there was no effort to hold the United States or its property accountable. In fact Michigan expressly exempts from taxation all public property belonging to the United States, 6 Mich. Stat. Ann., 1950, § 7.7, and these taxes were assessed from the beginning “subject to prior rights of the Federal Government.” Cf. S. R. A. v. Minnesota, 327 U. S. 558, 559, 561; City of New Brunswick v. United States, 276 U. S. 547.
The taxes imposed on Murray were styled a personal property tax by the Michigan statutes and it relies upon this to support its contention that they were actually laid against government property. However in passing on the constitutionality of a state tax “we are concerned only with its practical operation, not its definition or the precise form of descriptive words which may be applied to it.” Lawrence v. State Tax Commission, 286 U. S. 276, 280. Consequently in determining whether these taxes violate the Government’s constitutional immunity we must look through form and behind labels to substance. This is at least as true to uphold a state tax as to strike one down. Cf. Wisconsin v. J. C. Penney Co., 311 U. S. 435, 443-445; Capitol Greyhound Lines v. Brice, 339 U. S. 542. Due regard for the State’s power to tax requires no less. As applied — and of course that is the way they must be judged — the taxes involved here imposed a levy on a private party possessing government property which it was using or processing in the course of its own business. It is not disputed that Michigan law authorizes the taxation of the party in possession under such circumstances. Cf. Detroit Shipbuilding Co. v. Detroit, 228 Mich. 145, 199 N. W. 645; City of Detroit v. Gray, 314 Mich. 516, 22 N. W. 2d 771.
In their practical operation and effect the taxes in question are identical to those which we upheld in Nos. 26 and 37 on persons using exempt real property. We see no essential difference so far as constitutional tax immunity is concerned between taxing a person for using property he possesses and taxing him for possessing property |he uses when in both instances he uses the property for his own private ends. Nor have we been pointed to anything else which would bar a State from taxing possession in such circumstances. Cf. Carstairs v. Cochran, 193 U. S. 10. Lawful possession of property is a valuable right when the possessor can use it for his own personal benefit.
It is true that the particular Michigan taxing statutes involved here do not expressly state that the person in possession is taxed “for the privilege of using or possessing” personal property, but to strike down a tax on the possessor because of such verbal omission would only prove a victory for empty formalisms. And empty formalisms are too shadowy a basis for invalidating state tax laws. Cf. Henneford v. Silas Mason Co., 300- U. S. 577, 582. In the circumstances of this case the State could obviate such grounds for invalidity by merely adding a few words to its statutes. Yet their operation and practical effect would remain precisely the same.
There is no claim that the challenged taxes discriminate against persons holding government property. To the contrary the tax is a general tax which applies and has been applied throughout the State. If anything the economic burden on the United States is more remote and less certain than in other cases where this Court has upheld taxes on private parties. Of course the Government will eventually feel the financial burden of at least some of the tax but the one principle in this area which has heretofore been clearly settled is that the imposition of an increased financial burden on the Government does not by itself invalidate a state tax.
The respondents rely heavily on United States v. Allegheny County, 322 U. S. 174. Petitioners on the other hand contend that the decision in Allegheny is inconsistent with the general trend of our decisions in this field, that it has already been distinguished to the point where it retains no meaningful vitality and that it is erroneous. However that may be, we do not think that case is controlling, essentially for the reasons set forth in United States v. City of Detroit, ante, p. 466. In Allegheny the Court emphasized that the tax against Mesta Machine Company was, in its view, a general property tax laid on government property as such. The Court pointed out that the State had “made no effort to segregate Mesta’s interest and tax it.” The question was expressly reserved whether the State could tax a person possessing government property for the possession and use of such property in connection with his own profit-making activities. Here, however, state law specifically authorizes assessment against the person in possession. And the taxing authorities were careful not to attempt to tax the Government’s interest in the property.
In all important particulars the taxes imposed here are very similar to that upheld in Esso Standard Oil Co. v. Evans, 345 U. S. 495, on the storage of gasoline for the United States. A tax on storage is not intrinsically different from a tax on possession, at least where in both instances the private party is holding the property for his own gain. The tax in Esso was measured by the quantity of government gasoline stored while the taxes here are measured by the value of government property possessed but such technical distinction is of no significance in determining whether the Constitution bars this tax and is completely unrelated to any rational basis for governmental tax immunity.
We find nothing in the Constitution which compels us to strike down these state taxes. There was no discrimination against the Federal Government, its property or those with whom it does business. There was no crippling obstruction of any of the Government’s functions, no sinister effort to hamstring its power, not even the slightest interference with its property. Cf. M’Culloch v. Maryland, 4 Wheat. 316. In such circumstances the Congress is the proper agency, as we pointed out in United States v. City of Detroit, to make the difficult policy decisions necessarily involved in determining whether and to what extent private parties who do business with the Government should be given immunity from state taxes.
The judgment of the Court of Appeals is reversed and the cause is remanded for further proceedings not inconsistent with this opinion.
7 It is so ordered.
Opinion of
Mr. Justice Frankfurter.
Adjustment of the interpenetrating factors involved in the Nation-State relation of our federal system, insofar as they are amenable to adjudication, is a subtle and complicated process. It precludes easy application even of accepted legal formulas. Particularly is this true when the taxing power of the States is asserted against claims of intrusion into areas reserved to the Nation. In this domain it is asking too much for rules of certainty and simplicity in application that are hardly to be found in any live branch of the law. Even the Rule Against Per-petuities has only precarious certainty. The necessity for judicial accommodation between the intersecting interests of the States’ power to tax and the concerns of the Nation in carrying on its government presents problems solutions for which cannot be sought by a formula assuring a bright, straight line of decisions. Accordingly, we have been admonished in the leading modern case dealing with these problems that they require “the observing of close distinctions in order to maintain the essential freedom of government in performing its functions, without unduly limiting the taxing power which is equally essential to both Nation and State under our dual system.” James v. Dravo Contracting Co., 302 U. S. 134, 150.
The diversity of views expressed in these cases, even when there is concurrence in result, suggests the desirability of recalling, to use an old-fashioned phrase, “first principles.” After all, we are dealing with problems that have, howsoever they may have appeared in particular situations, an unbroken history of nearly a century and a half. Temerarious as the claim may appear, there is a residuum of continuity in the' reconciliation that the numerous cases since M’Culloch v. Maryland, 4 Wheat. 316 (1819), have made between the power of the States to tax and the restriction against laying a tax upon “the Government, its property or officers.” James v. Dravo Contracting Co., supra, at 149. The governing principles, as Chief Justice Marshall himself formulated them, bear quotation:
“ ‘That all subjects to 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.’
“ 'That the sovereignty of a State extends to everything which exists by its own authority, or is introduced by its permission; but not to those means which are employed by Congress to carry into execution powers conferred on that body by the people of the United States.’
“ 'That the attempt to use the power of taxation on 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 States have no power by taxation, or otherwise, to retard, impede, burden, or in any manner control the operation of the constitutional laws enacted by Congress, to carry into execution the powers vested in the General government.’ ” Weston v. City Council of Charleston, 2 Pet. 449, 467, as quoted by Mr. Justice Bradley in Railroad Co. v. Peniston, 18 Wall. 5, 38-39 (dissenting opinion).
No less, helpful in giving directions for the path of solution to our immediate problems are the comments on these principles by Mr. Justice Bradley, whose powers of penetrating analysis, particularly in this field, were in my view second to none.
“Whilst no one disputes the general power of taxation in the States, which is so elaborately set forth in the opinion of the majority, it must be conceded that there are limits to that power. The States cannot tax the powers, the operations, or the property of the United States, nor the means which it employs to carry its powers into execution. The government of the United States, within the scope of its powers, is supreme, and cannot be interfered with or impeded in their exercise.
“The case differs toto ccelo from that wherein the government enters into a contract with an individual or corporation to perform services necessary for carrying on the functions of government — as for carrying the mails, or troops, or supplies, or for building ships or works for government use. In those cases the government has no further concern with the contractor than in his contract and its execution. It has no concern with his property or his faculties independent of that. How much he may be taxed by, or what duties he may be obliged to perform towards, his State is of no consequence to the government, so long as his contract and its execution are not interfered with. In that case the contract is the means employed for carrying into execution the powers of the government, and the contract alone, and not the contractor, is exempt from taxation or other interference by the State government.” Railroad Co. v. Peniston, supra, at 41-42 (dissenting opinion).
When Mr. Chief Justice Hughes quoted the latter paragraph in support of the decision in James v. Bravo Contracting Co., supra, at 155, he impliedly indicated that some decisions that gave government contractors immunity from taxation for their property, profits, or purchases deviated from the traditional doctrines of implied governmental immunity, and that the decision in the Dravo case was essentially a return to orthodoxy as Mr. Justice Bradley had elucidated it. I venture to say that whatever deviations or even aberrations from true doctrine cases here and there and now happily laid to rest may disclose, there is a residuum of continuity over the long course of judicial adjustment of the States’ power to tax and the limits placed upon it by the implied immunity of the National Government from the demands of the state tax collectors. No decision has ever questioned that a tax cannot be laid upon “the Government, its property or officers,” James v. Dravo Contracting Co., supra, at 149, or, as it was phrased in United States v. Allegheny County, 322 U. S. 174, 177, “that possessions, institutions, and activities of the Federal Government itself in the absence of express congressional consent are not subject to any form of state taxation.” This at least has been a bright straight line running undeviatingly through the decisions of this Court. See Van Brocklin v. Tennessee, 117 U. S. 151; United States v. Alabama, 313 U. S. 274, 279.
As Mr. Chief Justice Stone stated for a unanimous court in Alabama v. King & Boozer, 314 U. S. 1, 9, the application, and therefore the outcome, in cases like those before us of these general principles “turns on the terms of the contract and the rights and obligations of the parties under it.” Nothing better illustrates the truth of this statement than a comparison of King & Boozer with Kern-Limerick, Inc. v. Scurlock, 347 U. S. 110, a case whose relevance is not minimized by the loud silence the Court’s present opinions accord it. Since “intergovernmental submission to taxation is primarily a problem of finance and legislation,” 347 U. S., at 122, it is immaterial that contracts by the Government have been purposefully drawn so as to vest title to the property that is the subject of the tax in the Government, and thereby withdraw it from the taxing power of the States.
If a legal decision were a vehicle for the expression of merely personal views, I might take satisfaction as a dissenter on the facts from the Allegheny decision that those who concurred in the result now for all practical purposes repudiate it. The principle on which the decision rested, that a tax cannot be laid on the property of the Federal Government, was not, as the opinion stated, questioned in that case. 322 U. S., at 177. The division turned on a relevant construction of the Pennsylvania taxing system in respect to fixtures in their enhancement of concededly taxable realty owned by'a government contractor. The Court found that the Pennsylvania scheme of taxation was in fact “the old and widely used ad valorem general property tax.” 322 U. S., at 184. As we are told by the Court in the present case, “Reviewing all the circumstances the Court [in Allegheny] concluded that the tax was simply and forthrightly imposed on the property itself, not on the privilege of using or possessing it.” But this is so, a fortiori, in the circumstances of Nos. 18 and 36 now before us. Surely the detailed analysis of my brother Whittaker of “the terms of the contract and the rights and obligations of the parties under it,” in relation to the taxing system of Michigan, demonstrates, if anything is demonstrable in the law, that the tax imposed has all the incidents of a general ad valorem property tax, and that it has them to a more conclusive degree than was true of the tax levied by Pennsylvania in the Allegheny case.

Assessor inscribed on tax roll: “Assessed Subject to Prior Rights of Federal Government.”
I cannot believe that the Court would outright reject the doctrine of constitutional immunity from taxation of the Government and its property. I cannot believe that the Court „is prepared frankly to jettison what has been part of our constitutional system for almost 150 years. But it does not save the principle to disregard it in practice. And it disregards it in practice to argue from the right of a State to levy an excise tax against a contractor for the enjoyment of property that gives him an economic advantage because it is otherwise immune from taxation, to the right of a State professedly and directly to lay an ad valorem property tax on what is indubitably government property. •/-
A totally different problem is presented by Nos. 26, 37, and 38. These cases present the question whether enjoyment of the use of property that carries special economic advantages to the user because, for one reason or another, the property as such cannot be the subject of a tax, is included within Chief Justice Marshall's principle that “all subjects over which the sovereign power of a state extends, are objects of taxation . . . Weston v. City Council of Charleston, 2 Pet. 449, 467. If a State may impose an excise tax on something that gives advantage or pleasure, such as the practice of a particular profession, why is it not also a taxable advantage that is had from being able to use property that for reasons extraneous to the user is not subject to the taxing power? Cf. Watson v. State Comptroller, 254 U. S. 122.
The only right that a taxpayer can assert against the state taxing power on the basis of governmental immunity is a “derivative one,” James v. Dravo Contracting Co., 302 U. S. 134, 158, supra, and if he is to resist the exercise of this power he must stand in the Government’s shoes. The immunity that he asserts is the Government’s immunity, not his own. In taxing the enjoyment or use of property that is itself free from taxation, the State taxes an interest of the taxpayer, not of the Federal Government, and the tax is not laid on “the Government, its property or officers.” The taxpayer is not immune from a tax because as a matter of dollars and cents it may affect the Government. To be sure, the excise in Nos. 26, 37, and 38 is measured by the value of the property, so that if the property were directly taxed the tax bill would be the same. But if the enjoyment of otherwise tax-free property is something different from the property itself for purposes of taxation, it does not lose this characteristic because the admeasurement is the same.
A principle with the uninterrupted historic longevity attributable to the immunity of government property from state taxation has a momentum of authority that reflects, if not a detailed exposition of considerations of policy demanded by our federal system, certainly a deep instinct that there are such considerations, and that the distinction between a tax on government property and a tax on a third person for the privilege of using such property is not an “empty formalism.” The distinction embodies a considered judgment as to the minimum safeguard necessary for the National Government to carry on its essential functions without hindrance from the exercise of power by another sovereign within the same territory. That in a particular case there may in fact be no conflict in the exercise of the two governmental powers is not to the point. It is in avoiding the potentialities of friction and furthering the smooth operation of complicated governmental machinery that the constitutional doctrine of immunity finds its explanation and justification.
The danger of hindrance of the Federal Government in the use of its property, resulting in erosion of the fundamental command of the Supremacy Clause, is at its greatest when the State may, through regulation or taxation, move directly against the activities of the Government. Scarcely less is the danger when the subject of a tax, that at which the State has consciously and purposefully aimed in attaching the consequence of tax-ability, is the property of the Federal Government. It is not only that the likelihood of local legislation deliberately or unwittingly discriminatory against government property either by its terms or application may be enhanced. Even a nondiscriminatory tax, if it is expressly laid on government property, is more likely to result in interference with the effective use of that property, whether because of an ill-advised attempt by the tax collector to levy on the property itself or because it is sought to hold the Government or its officers to account for the tax, even if ultimately the endeavor may fail. The defense of sovereign immunity to a suit against government officers for the tax, or a suit to assert title to or recover property erroneously levied upon to satisfy a tax, may in practice be an inadequate substitute for the clear assertion of federal interest at the threshold.
The fact that a tax on a third party for the privilege of using government property may itself have an indirect impeding effect is no reason against a rule designed to avoid the more direct and obvious evil. Because a constitutional doctrine is not pushed to the logical extremities of its policy is no argument against maintaining it as far as it has historically extended. From the beginning a broad cloak of immunity for government property has been thought the best way to allay the danger of state encroachment on the national interest, and the character of our federal system and the relations between the Nation and the States have not in this regard so changed that the principle has become outmoded. _
If the distinctions between the taxes involved in these cases seem nice, it is because “nice distinctions are to be expected,” Galveston, H. & S. A. R. Co. v. Texas, 210 U. S. 217, 225, and they are none the worse for it. - Not to make them, to lump all these cases together as though some similarities and assumed similar consequences amount to identities, is to disregard a long, unbroken course of judicial history and practicalities of government that doubtless have led, under prior decisions of this Court, to the drawing of countless contracts covering the use of government property.
Accordingly, I dissent from the Court’s opinion in Nos. 18 and 36, and concur in the result in Nos. 26, 37, and 38.
Opinion of
MR. Justice Harlan.
Because all but two members of the Court consider that the taxes involved in these cases all stand or fall together, I deem it advisable to state my reasons for believing that these cases require different conclusions as to the constitutionality of the taxes involved.
In determining the constitutionality of a state tax against a claim of federal immunity, past cases in this Court have established a distinction between “property” and “privilege” taxes of one kind or another. That is, broadly speaking, a State may not constitutionally tax property owned by the Federal Government, even though the property is in private hands and the tax is to be collected from a private taxpayer, United States v. Allegheny County, 322 U. S. 174, but it may tax activities of private persons, even though these activities involve the use of government property and the value or amount of such property becomes the partial or exclusive basis for the measurement of the tax. Curry v. United States, 314 U. S. 14; Esso Standard Oil Co. v. Evans, 345 U. S. 495. Cf. Plummer v. Coler, 178 U. S. 115; Educational Films Corp. v. Ward, 282 U. S. 379. Although the opinions of the Court in the present cases stop short of repudiating this established distinction, they seem to me to blur it to the point where the extent of its future application is left confused and uncertain.
In view of this Court’s past decisions in the privilege-tax cases, I agree with the majority today that the lessee’s and user’s tax in Nos. 26, 37 and 38, construed by the state court to be a tax on the privilege of using tax-exempt property, is constitutional as applied. The dissenting opinion, which I do not believe can be reconciled with these past decisions, concludes that the tax imposed upon those using tax-exempt property for private profit should be regarded in substance as a tax on the property itself because the privilege tax is measured by the full value of the leased or used property, rather than merely by the value of the lessee’s or user’s interest.
In effect, it seems to me that the dissenters equate the measure of the tax with the subject of the tax. But I do not think that the formula here employed by Michigan to measure these taxes can be meaningfully distinguished from that applied in the Alabama use tax upheld in Curry v. United States, supra. There the use tax collected from a government contractor was measured by a percentage of the full value of government-owned property used by the contractor to execute its obligations. Indeed, the only distinction I can see is that the compensating use tax in Curry was imposed just once, whereas the privilege tax in Michigan is assessed yearly; but having regard to the wide latitude of a State’s taxing power within the due-process limitations of the Fourteenth Amendment, I can hardly believe that this difference points to a contrary constitutional result. The decision in Esso Standard Oil Co. v. Evans, supra, which upheld a state tax assessed to a private taxpayer on the privilege of storing gasoline although the tax was measured in part by the amount of government gasoline stored multiplied, by a fixed rate, provides further support for this conclusion. And in both of those cases, as is true here, the Government bore the full economic burden of the state taxes.
It should be observed that the state taxes here, as those in Curry and Esso Standard Oil Co., do not operate in a discriminatory fashion by so measuring the tax on use or activities as to impose an unequal tax burden on lessees or users of government property vis-a-vis lessees, users, or owners of other tax-exempt or nonexempt property. And since this is so, I cannot agree with the dissenting opinion that this Court’s view of the state legislature’s purpose in enacting the statute should affect our determination of its constitutionality. Although Michigan here sought to equalize tax burdens on users of normal and tax-exempt property, or perhaps even to by-pass Alie- gheny, I think it hardly repaying to speculate on the motives behind a local tax, as long as it is otherwise constitutionally permissible. Finally, it should be noted that assessment of the privilege tax to the user of government property in Nos. 37 and 38 would present a quite different problem if the user were deemed to be an instrumentality of the United States Government, but petitioners in those cases make no such showing, and I do not understand the dissenters here to rely on such a ground.
In Nos. 18 and 36 the Court'holds that a tax which the dissenting opinions convincingly show is nothing but a conventional ad valorem personal property tax should be regarded instead as a tax upon the possession of government property privately used. This the Court finds constitutionally indistinguishable from the tax upon the use of government property privately possessed which has been upheld as a privilege tax in Nos. 26, 37, and 38. That is to say, the Court finds that the Government’s property here was simply the measure, and not the subject matter, of a tax which was in effect imposed on the privilege of possessing property used for private gain.
In so holding, the Court, proceeding on the premise that Detroit’s characterization of this tax as a personal property tax does not bind us, Carpenter v. Shaw, 280 U. S. 363, 367-368, relies on the circumstances that this government property was used for private gain, that the tax was collectible under the statute from the subcontractor and not from the Government or out of its property, and that the tax was nondiscriminatory. But all of these factors were present in United States v. Allegheny County, supra, where the Court struck down a local tax also cast in the traditional language of a “property” tax. Although the Court here purports to distinguish Allegheny, it seems to me that the authority of that case has now been reduced almost to the vanishing point, for neither the tax statute here nor that in Allegheny qualified application of the tax to property employed in private commercial activity.
What has happened in these two groups of cases no doubt reflects the difficulty of reconciling Allegheny with the privilege tax cases, and bears witness to the truth of Mr. Justice Jackson’s statement in Allegheny that in the evolution of the law in this difficult field “the line between the taxable and the immune has been drawn by an unsteady hand.” 322 U. S., at 176. Since the economic incidence of a state tax on the Federal Government is no longer a controlling factor, James v. Dravo Contracting Co., 302 U. S. 134; Alabama v. King & Boozer, 314 U. S. 1, and since the use of federally owned property as the measure, by value or amount, of a tax on the privilege of using (Curry v. United States, supra) or storing (Esso Standard Oil Co. v. Evans, supra) such property is permissible, the distinction between “property” and “privilege” taxes as a yardstick for judging constitutionality when both taxes are collectible from a private taxpayer holding the property is certainly left in a high degree of artificiality. See Powell, Intergovernmental Tax Immunities, 58 Harv. L. Rev. 633, 757; cf. Society for Savings v. Bowers, 349 U. S. 143, 148. This is certainly so where the property tax applies to property used by a private party in some activity which is a proper subject of state taxation, see M’Culloch v. Maryland, 4 Wheat. 316, 429, and where, as here, the State does not seek to accomplish what would in any event be procedurally impossible because of the doctrine of sovereign immunity from suit — enforcement of a lien asserted against government property. It is quite understandable, therefore, that the Court should wish to minimize the importance of that distinction.'
But by holding that the ad valorem personal property taxes involved in Nos. 18 and 36 should be regarded as “privilege” taxes, it seems to me that the Court has injected further uncertainties into a field already plagued by excessive refinements. For until today the line between property and privilege taxes, if “drawn by an unsteady hand,” was at least visible. A State could not tax government property, even though the property was in the hands of, and the tax was collectible only from, private persons. However, it now appears that not all property taxes are indeed “property” taxes for purposes of constitutional immunity, even though so characterized or construed by state authorities. Henceforth, apparently, we must determine whether the tax which a State has drafted as and denominated a “property” tax could, had the State so desired, have been constitutionally imposed as a “privilege” tax, measured by the value of the taxed property, upon some activity embracing the' use of the property.
In my opinion, so fluid a rule incorporating these elusive additional distinctions will hardly help those who in their daily business must negotiate contracts for or with the Government. Indeed, the difficulty of its application is effectively illustrated by the divergence of opinion in these very cases, wherein five members of the Court have concluded that these particular “property” taxes are in reality “privilege” taxes. Rather than add further complications to an already troubled area of the law, I think the preferable course is to follow our past cases, upon which those contracting for the Government have undoubtedly relied, and to leave to Congress the task of adjusting to the needs of today the law which Allegheny and the privilege tax cases have created.
For these reasons, I have joined the opinion of the Court in Nos. 26, 37 and 38, and the dissenting opinion of Mr. Justice Whittaker in Nos. 18 and 36.
The relevant statutory provisions are set forth in full in 6 Mich. Stat. Ann., 1950, §§ 7.1, 7.10, 7.81, and Tit. VI, c. II, § 1, and Tit. VI, e. IV, §§ 1, 7, 26, 27, of the Charter of the City of Detroit. They provide in part that “The owners or persons in possession of any personal property shall pay all taxes assessed thereon. ... In case any person by agreement or otherwise ought to pay such tax, or any part thereof, the person in possession who shall pay the same may recover the amount from the person who ought to have paid the same . . . .”
For purposes of this case we assume that the United States had full title to the property not just a bare security interest. But cf. S. R. A. v. Minnesota, 327 U. S. 558, affirming 213 Minn. 487, 7 N. W. 2d 484, and 219 Minn. 493, 18 N. W. 2d 442; Land O’Lakes Dairy Co. v. Wadena County, 338 U. S. 897, affirming 229 Minn. 263, 39 N. W. 2d 164; Offutt Housing Co. v. Sarpy County, 351 U. S. 253.
