ERROR TO THE SUPREME COURT
OF THE STATE OF ILLINOIS
1. While a state may forbid a foreign corporation to do business within its jurisdiction, or to continue it, and may fix conditions under which the exercise of the privilege may be allowed, it may not do so by imposing upon the corporation a sacrifice of its rights under the federal Constitution. Pp. 272 U. S. 507-509
2. At the end of the period for which a license to do local business has been granted to a foreign corporation, the state may impose as a condition precedent to a renewed license that its valid laws shall have been complied with in the past. P. 272 U. S. 514.
3. But the state may not make past compliance with an unconstitutional tax a condition precedent to renewal of the license. P. 272 U. S. 514.
4. A decision of a state supreme court construing a local law taxing foreign corporations as imposing a privilege tax, rather than a property tax, is binding on this Court; but this Court, in determining chanroblesvirtualawlibrary
the applicability of the equal protection clause of the Fourteenth Amendment, must decide independently whether the tax is part of the condition upon which admission to do business in the state is permitted, and is merely a regulating license by the state to protect the state and its citizens in dealing with such corporation, or whether it is a tax law for the purpose of securing contributions to the revenue of the state as they are made by other taxpayers of the state. Pp. 272 U. S. 509-511.
5. A foreign corporation which is duly admitted to do business in a state is to be classified with similar domestic corporations in testing the equality of the laws enacted for the purpose of raising revenue. P. 272 U. S. 511.
6. An Illinois tax on the local net receipts of foreign insurance companies was long construed and applied as a tax on personal property; and, like other personal property taxes, partly by law and partly by custom, was assessed on only 30% of the full value; but afterwards, by a change of construction, it was held to be an occupation or privilege tax, laid on such corporations annually, as a condition to their right to do business in Illinois, with the result that all of their local net income was taxed at the rate applicable to personal property, while domestic corporations of the same class and engaged in the same kinds of business paid only a tax on their personal property, assessed at the reduced valuation. Held a discrimination which denied the equal protection of the laws to a foreign corporation which had renewed its license in Illinois from year to year, built up a large business and goodwill in that state, and had many agents there and extensive records containing information concerning its policies and policyholders. P. 272 U. S. 516.
317 Ill. 366 reversed.
Error to a judgment of the Supreme Court of Illinois which affirmed a judgment dismissing the bill of the Insurance Company, a New York corporation, against Carr, the treasurer and tax collector of Cook County, Illinois. The bill prayed an injunction to prevent distraint of the plaintiff's property under a warrant for taxes due under an Illinois law which the bill challenged as unconstitutional under the state constitution and the equal protection clause of the Fourteenth Amendment. Harding, treasurer of Cook County, was substituted in this Court for Carr, his predecessor in office. chanroblesvirtualawlibrary
MR. CHIEF JUSTICE TAFT delivered the opinion of the Court.
This is a writ of error under § 237 of the Judicial Code to the judgment of the Supreme Court of Illinois affirming a decree of the Superior Court of Cook County dismissing the bill of the Hanover Fire Insurance Company, a corporation of New York, against Patrick J. Carr, County Treasurer and ex officio tax collector of Cook county, Illinois. The prayer was for an injunction to prevent the distraint of the property of the complainant under a warrant for the collection of $10,678.50 as taxes due under a law of Illinois, which law, the bill averred, denied to the complainant the equal protection of the laws under the Fourteenth Amendment of the federal Constitution.
The defendant filed an answer denying the claims of the bill and, after a reply, the case was heard by the trial court, which made findings of fact in its decree based on a stipulation by the parties, and entered a decree as set forth below.
The law in question reads as follows:
"Foreign Companies. -- Tax on Net Receipts. Section 30. Every agent of any insurance company incorporated by the authority of any other state or government shall return to the proper officer of the county, town, or municipality
in which the agency is established, in the month of May annually, the amount of the net receipts of such agency for the preceding year, which shall be entered on the tax lists of the county, town, and municipality, and subject to the same rate of taxation, for all purposes -- state, county, town and municipal -- that other personal property is subject to at the place where located, said tax to be in lieu of all town and municipal licenses, and all laws and parts of laws inconsistent herewith are hereby repealed: Provided, that the provisions of this section shall not be construed to prohibit cities having an organized fire department from levying a tax, or license fee, not exceeding two percent in accordance with the provisions of their respective charters, on the gross receipts of such agency, to be applied exclusively to the support of the fire department of such city."
Cahill's Ill.Rev.Stat.1925, c. 73, § 159, p. 1405.
This had been in force since 1869, and was part of the Act of March 11 of that year, entitled "An act to incorporate and to govern fire, marine and inland navigation insurance companies doing business in the State of Illinois." The section was amended to the above form by an Act approved May 31, 1879.
By § 22 and other sections of the original Act of 1869 (Cahill's Ill.Rev.Stat.1925, c. 73, § 150, p. 1402), it was made unlawful for a foreign insurance company to transact any insurance business in the state unless it had a prescribed amount of capital, appointed an attorney in the state on whom process of law could be served, filed a properly certified copy of the charter or deed of settlement of the insurance company, showing its name and the place where located, the amount of its capital and a detailed statement of its assets, together with its indebtedness, the losses adjusted and unpaid, the amount incurred and in process of adjustment, and a copy of its last annual report. It was required also to deposit with the Director chanroblesvirtualawlibrary
of Trade and Commerce of the state, for the benefit and security of the policyholders residing in the United States, a sum of not less than $200,000 in 6 percentum stock of the United States or the State of Illinois, or approved mortgage securities, with a provision that, so long as the company should continue solvent and comply with the laws of the state, it might collect the interest on these securities. The law provided that it should not be lawful for the agents of the company to transact business without procuring annually from the Director of Trade and Commerce the authority stating that such company had complied with all the requisitions of the act which applied to it, and that any violation of the provisions of the act should subject the one violating it to a penalty not exceeding $500 for each violation; that such insurance companies should make annual statements of their condition and affairs to the Director of Trade and Commerce in the same manner and in the same form as similar insurance companies organized under the laws of the state, on or before the first day of March in each year for the year ending on the preceding 30th of September. The insurance superintendent was given authority by the same act to investigate affairs of the foreign companies, such investigation to be at the expense of the company, and if he found the condition of any one unsound, to close up the business of the company by application to the circuit court of the county in which it had its principal office. By the same act, each foreign company was required to pay $30 for filing the charter, $10 for filing the annual statement required, and $2 for each certificate of authority for agents, and certain other fees of a similar character. Paragraphs 150, 152, 156, Cahill's Ill.Rev.Stat.1925, c. 73.
By the Act of June 28, 1919 (Cahill's Ill.Rev.Stat.1925, c. 73, § 79, p. 1390), it was provided that each nonresident corporation licensed and admitted to do an insurance chanroblesvirtualawlibrary
business in the state should pay an annual state tax for the privilege of so doing, equal to 2 percentum of the gross amount of premiums received during the preceding calendar year on contracts covering risks within the state after certain reductions; that the tax should be in lieu of all license fees or privilege or occupation taxes levied or assessed by any municipality in the state, and that no municipality should impose any license fee, privilege, or occupation tax upon such corporation for the privilege of doing an insurance business therein, but this should not be construed to prohibit the levy and collection of any state, county, or municipal taxes upon the real and personal property of such corporations, or the levying and collection of taxes authorized by § 30, above quoted.
By § 12 of the same act (Cahill's Ill.Rev.Stat., c. 73, § 90, p. 1391), it was provided that, if any corporation should fail or neglect to make any report, or to refuse to pay any tax assessment within 30 days after the same became due, the Department of Trade and Commerce should have power to revoke its license to transact the business of insurance in the state, or to suspend it until the reports were filed or the taxes paid.
The complainant insurance company complied with the requirements of § 22 and other unrepealed sections of the Act of 1869 and paid the 2 percent tax on its premiums received as provided by the Act of 1919.
By the General Revenue Act of Illinois, in force since February 25, 1898 (Cahill's R.S. 1925, c. 120, § 329, p. 2042), personal property is to be valued at its fair cash value, which value is to be set down in one column to be headed "Full Value," and one-half part thereof is to be ascertained and set down in another column headed "Assessed Value." The one-half value of all the property so ascertained and set down is to be the value for all purposes of taxation. It is further stipulated in this case and found by the trial court that, for the chanroblesvirtualawlibrary
year 1923, and for many years prior thereto, there has been what is called an equalization which systematically and intentionally reduces the amount set down in the column headed "Full Value" to not more than 60 percent of the actual market value of the personal property returned, and by further reducing this by 50 percent to make the assessed value in accord with the statute, the tax is collected only on 30 percent of the full value.
This suit presents the question of the validity of the assessment made by taxing officers under § 30 for the year 1922. The Supreme Court of Illinois, in People v. Barrett, 309 Ill. 53, in an opinion announced June 20, 1923, near the close of the year for which the assessment of 1922 was made, held that the tax under § 30 was an occupation tax, and that no reduction should be permitted to foreign insurance companies in the assessment for taxation of their annual net receipts. The superior court found that the actual amount of net cash receipts of the complainant company was $90,824, less by $45,000 than the amount reported by the Board of Review, so that its decree forbade the collection of more than $7,184.18, instead of $10,678.50, for which the warrant had issued, but denied further relief. The complainant insisted that, under the previous practice and proper construction of § 30 as a property tax, with due equalization and debasement, the tax assessed should have been $2,155.24, and that this, if anything, is all that should be collected from it. The supreme court, by a divided court, three judges dissenting, affirmed the decree of the superior court. Hanover Fire Insurance Co. v. Carr, 317 Ill. 366.
The petitioner is an insurance corporation organized under the laws of the State of New York. By its charter, it is authorized to do a business of insurance against the hazard of fire, marine perils, inland navigation, tornado, theft, explosion, property damage to automobiles, and chanroblesvirtualawlibrary
other property by collision, crop insurance, and other similar lines of insurance against specified hazards. There are in Illinois domestic insurance companies which do business in all of such risks. In Fidelity & Casualty Co. v. Board of Review, 264 Ill. 11 decided in 1914, the Supreme Court held that the only insurance companies whose receipts come within § 30 are foreign fire, marine, and inland navigation insurance companies doing business in the state. And if they do business in the other hazards above stated, as the complainant and petitioner is authorized to do, then they must pay taxes on their net receipts made not only from fire, marine, and inland navigation company business, but also from the other hazards.
The situation, then, is that a foreign fire, marine, and inland navigation insurance company like the petitioner must pay at a rate percentum equivalent to that imposed on personal property a tax on the cash amount or 100 percent of its net receipts from all its insurance business. A domestic fire, marine, and inland navigation insurance company pays no tax on its net receipts from any kind of insurance. Both pay on their personal property other than net receipts as of a fixed date in each year on an assessment of 30 percent of its full value.
The Supreme Court of Illinois for many years held the payment of a tax on the net receipts was a tax on personal property. Walker v. Springfield, 94 Ill. 364; City of Chicago v. James, 114 Ill. 479; Chicago v. Phoenix Insurance Company, 126 Ill. 276; National Fire Insurance Co. v. Hanberg, 215 Ill. 378; People v. Cosmopolitan Fire Insurance Co., 246 Ill. 442. The net receipts were the gross receipts from each agency after the operating expenses had been deducted. The losses from fire and other risks assumed were not deducted. National Fire Insurance Co. v. Hanberg, 215 Ill. 378. It is quite apparent from reading these cases that, in practice, chanroblesvirtualawlibrary
the net receipts were treated as personal property and their assessment was by equalization and debasement reduced from full value as all other personal property, until the decisions in People v. Kent, 300 Ill. 324, (1921), and in People v. Barrett, 309 Ill. 53.
The general principle upon which the Supreme Court of Illinois holds the tax complained of herein to be valid is that the payment of it is part of the condition which the petitioner, as a foreign insurance company, is obliged to perform in order to maintain and retain its right to do business in the state. It was settled in 38 U. S. 203, and Looney v. Crane Co., 245 U. S. 178, 245 U. S. 188. It is illustrated in cases in which a provision of a state law revoking the license of a foreign corporation for exercising its constitutional right to remove suits brought against them from the state courts to the federal courts has been held void, Terral v. Burke Construction Co., 257 U. S. 529; in cases in which the state has vainly attempted to subject foreign corporations to a payment of a tax which is a tax not only on the property of chanroblesvirtualawlibrary
the corporation in the state, but also on its property without the state, in violation of the due process clause of the Fourteenth Amendment, Western Union Telegraph Co. v. Kansas, 216 U. S. 1; St. Louis Cotton Compress Co. v. Arkansas, 260 U. S. 346, and finally in cases of a class to which it is contended the present case belongs, where a tax or license law operates to deny to the foreign corporation the equal protection of the laws, Southern Railway Co. v. Greene, 216 U. S. 400; Air Way Corp. v. Day, 266 U. S. 71. In the former of these last two cases, a railway corporation of another state had come into Alabama and secured a license to do business therein as an intrastate railway, and, in course of that business, had acquired in the state property of a fixed and permanent nature upon which it had paid all the taxes levied by the state. It was held that a new and additional franchise tax for the privilege of doing business within the state, not imposed upon domestic corporations doing business in the state of the same character, violated the equal protection clause. In Air Way Corp. v. Day,@ a corporation of Delaware had much or all of its property in Ohio, where it was duly authorized to do business. Thereafter, a law of Ohio imposed five cents a share upon a certain proportion of nonpar shares authorized by the State of Delaware which the court found to be arbitrary, and not based on a classification of foreign corporations having any reasonable basis.
In the present case, there is no such permanent investment in the State of Illinois as there was in the Greene case in Alabama, but the averments of the bill show that the complainant has from year to year secured renewal of its license in the State of Illinois, and has, through many years past, built up a large goodwill in the State if Illinois and has associated with it a large number of agents in the various counties of the state whose connection with it has resulted in a large and profitable business to chanroblesvirtualawlibrary
the complainant, and that it has large numbers of records containing information respecting its policyholders, the character and nature of their policies, and other records, the value of all of which would be destroyed if excluded from the state by a denial of the equal protection of the laws. In the Greene case, the license was indefinite. In this case, it must be renewed from year to year, but the principle is the same, that, pending the period of business permitted by the state, the state must not enforce against its licensees unconstitutional burdens.
It is insisted that we must accept the construction of § 30 by the state supreme court, and, as the tax levied is sustained by its construction, and has been held by the court to be an indispensable condition upon which the petitioner may continue to do business in Illinois, this Court is bound by both those conclusions.
It is true that the interpretation put upon such a tax law of a state by its supreme court is binding upon this Court as to its meaning; but it is not true that this Court, in accepting the meaning thus given, may not exercise its independent judgment in determining whether, with the meaning given, its effect would not involve a violation of the federal Constitution. As said by this Court in St. Louis Southwestern Railway v. Arkansas, 235 U. S. 350, at 235 U. S. 362, where the question was whether a tax law violated the equal protection clause of the Fourteenth Amendment:
"Upon the mere question of construction, we are, of course, concluded by the decision of the state court of last resort. But when the question is whether a tax imposed by a state deprives a party of rights secured by the federal Constitution, the decision is not dependent upon the form in which the taxing scheme is cast, nor upon the characterization of that scheme as adopted by the state court. We must regard the substance, rather than the
form, and the controlling test is to be found in the operation and effect of the law as applied and enforced by the state."
This view has been upheld in many cases. Western Union Telegraph Co. v. Kansas, 216 U. S. 1, 216 U. S. 27; Ludwig v. Western Union Telegraph Co., 216 U. S. 146; Sioux Remedy Co. v. Cope, 235 U. S. 197; St. Louis Cotton Compress Co. v. Arkansas, 260 U. S. 346. In the last case, the question was whether a foreign corporation doing business in Arkansas could be required by a law of the state to pay a so-called occupation tax upon premiums paid by it to insurance companies not doing business in Arkansas for insurance upon property of the corporation in Arkansas, the policies having been issued and accepted outside of Arkansas. This Court held the tax invalid as a violation of the Fourteenth Amendment. In reaching this conclusion, this Court said (p. 260 U. S. 348):
"The Supreme Court justified the imposition as an occupation tax -- that is, as we understand it, a tax upon the occupation of the defendant. But this Court, although bound by the construction that the supreme court may put upon the statute, is not bound by the characterization of it so far as that characterization may bear upon the question of its constitutional effect."
In subjecting a law of the state which imposes a charge upon foreign corporations to the test whether such a charge violates the equal protection clause of the Fourteenth Amendment, a line has to be drawn between the burden imposed by the state for the license or privilege to do business in the state and the tax burden which, having secured the right to do business, the foreign corporation must share with all the corporations and other taxpayers of the state. With respect to the admission fee, so to speak, which the foreign corporation must pay to become a quasi-citizen of the state and entitled to chanroblesvirtualawlibrary
equal privileges with citizens of the state, the measure of the burden is in the discretion of the state and any inequality as between the foreign corporation and the domestic corporation in that regard does not come within the inhibition of the Fourteenth Amendment, but, after its admission, the foreign corporation stands equal, and is to be classified, with domestic corporations of the same kind.
In this class of cases, therefore, the question of the application of the equal protection clause turns on the stage at which the foreign corporation is put on a level with domestic corporations in engaging in business within the state. To leave the determination of such a question finally to a state court would be to deprive this Court of its independent judgment in determining whether a federal constitutional limitation has been infringed. While we may not question the meaning of the tax law as interpreted by the state court in the manner and effect in which it is to be enforced, we must reexamine the question passed upon by the state court as to whether the law complained of is a part of the condition upon which admission to do business of the state is permitted, and is merely a regulating license by the state to protect the state and its citizens in dealing with such corporation, or whether it is a tax law for the purpose of securing contributions to the revenue of the state as they are made by other taxpayers of the state. Our power and duty in this regard must follow from our decisions, and, while the exact question has not heretofore been considered, there can be no doubt that our conclusion finds its complete support in the analogies of other cases in which we have had to determine what our duty is in dealing with the alleged invalidity of state legislation. Bailey v. Alabama, 219 U. S. 219, 219 U. S. 239; Corn Products Co. v. Eddy, 249 U. S. 427, 249 U. S. 432; Appleby v. New York, 271 U. S. 364; Truax v. Corrigan, 257 U. S. 312, 257 U. S. 324-325. What, therefore, we have chanroblesvirtualawlibrary
to decide here is whether the application of § 30 can be one of the conditions upon which the insurance company is admitted to do business in Illinois, or whether, under the law of 1919, the authority granted by the Department of Trade and Commerce for which the company paid 2 percent of gross premiums received the previous year by it put it upon a level with domestic insurance companies doing business of the same character.
It is plain that compliance with § 30 is not a condition precedent to permission to do business in Illinois. The state supreme court concedes this, but its reasoning that payment of the tax under the section is a condition to its doing business in Illinois which may vary at the will of the state, without regard to taxes on similar domestic corporations, is shown by the following passages:
"The fact that a tax is a privilege tax does not necessarily require that it be paid as a condition precedent to entering the state. Such a condition, being precedent, could, of course, be met but once. However, the greatest financial benefit to such a company flows from the continuation of the privilege to do business. Compensation for that privilege should be based on the benefits actually derived from the business done under such privilege, and such compensation must necessarily be assessed in some manner after the business is done and the benefits thereof received. Section 30 provides the method by which the amount of this compensation shall be determined and assessed."
"Section 22 of the act relating to fire, marine and inland navigation insurance, aside from specifying certain requirements imposed upon foreign insurance companies seeking to do business in this state and specifying what shall be necessary to secure the right of entry, further provides:"
"Nor shall it be lawful for any agent or agents to act for any company or companies referred to in this section, directly or indirectly, in taking risks or transacting
the business of fire and inland navigation insurance in this state, without procuring annually from the Insurance Superintendent a certificate of authority stating that such company has complied with all the requisitions of this act which apply to such companies and the name of the attorney appointed to act for the company."
"The provisions of § 30 requiring the return of net receipts of this tax are a part of the 'requisitions of this act.' It is evident, therefore, from the language in § 22 quoted that, before appellant may continue in business in this state, its agent shall procure annually from the Insurance Superintendent of the state or his successor in law a certificate showing that it has complied with the requirements of § 30 with reference to this tax. Such certificate cannot be lawfully issued without such showing. This act provides no other means of collecting such tax, and no reference is made for its collection "
The court then refers to another act, which imposes a penalty for violation of § 30 by placing risks or policies of indemnity upon property in any other manner than through its regularly authorized agents, and justifying a revocation of the license for a period of not less than 90 days, and that it shall not be reissued until it appears that there is complete compliance with the laws of the state governing such companies and until it has been shown that all taxes and penalties and expenses due thereunder have been paid.
"It seems clear, therefore' says the court (p. 375), 'that this tax is levied as compensation for the privilege of continuing their business in the state."
"While the Act of 1919 . . . imposes an annual state tax equal to 2 percent on the gross amount of premiums received by any foreign insurance company during the preceding year, . . . that fact does not show that the tax imposed on the business of fire insurance by § 30 is not likewise a tax for the privilege of doing
business. The Act of 1919 requires that the tax there levied be paid to the state. Section 30 requires that the tax be apportioned among the state and the different municipalities of the situs of the agency. A valid reason is seen for this distribution of the tax. The foreign fire insurance company takes its net proceeds largely from the vicinity of its agencies, and it is but just that it return to the municipality in which its agency is located something in lieu of the taxes that would otherwise be realized from such net receipts as are taken away."
The view of the court seems to be that the constitutional necessity for equal application of the laws of the state to foreign and domestic corporations properly engaged in business is avoided if only the state provides that failure to comply with the laws during the period or at the end of the period for which the license runs justifies a revocation of the license pending the period, or a refusal to grant a new license for the following year. We do not think the state may thus relieve itself from granting the equal protection of its laws to a foreign company which has met the conditions precedent to its becoming a quasi-domestic citizen. Of course, at the end of the year for which the license has been granted, the state may, in its discretion, impose as conditions precedent for a renewed license past compliance with its valid laws; but that does not enable the state to make past compliance with § 30 a condition precedent to a renewal of the license, if as we find that section violates the Fourteenth Amendment, for, as already said, while a state may forbid a foreign corporation to do business within its jurisdiction, or to continue it, it may not do so by imposing on a corporation a sacrifice of its constitutional rights. We have said in Cheney Bros. Co. v. Massachusetts, 246 U. S. 147, and in Kansas City, etc., Railroad Co. v. Stiles, 242 U. S. 111, 242 U. S. 118, that a state does not surrender or abridge its power to change and revise chanroblesvirtualawlibrary
its taxing system and tax rates by merely licensing or permitting a foreign corporation to engage in local business and acquire property within its limits, and that a state may impose a different rate of taxation upon a foreign corporation for the privilege of doing business within the state than it applies to its own corporations upon the franchise which the state grants them; but the decision in Southern Railway Co. v. Greene, supra, shows that this power to change the tax imposed on a foreign corporation as a condition for the license of continuing business is not unlimited, and that any attempt in a renewal to vary the terms of the original license which, however indirectly, enforces a new condition upon the corporation and involves a deprivation of its federal constitutional rights cannot be effective. The state, in dealing with foreign corporations, may properly and without discrimination as between them and domestic companies regulate the former by a provision that for a failure by them to comply with any valid law governing the conduct of their business in the state the license already granted may be revoked. That is a legitimate condition in the treatment of foreign companies which do not have property and home within the state. It is a police regulation. But the power thus to revoke a license for breach of a law can only be validly exercised if the law be a constitutional one. By compliance with the valid conditions precedent, the foreign insurance company is put on a level with all other insurance companies of the same kind, domestic or foreign within the state, and tax laws made to apply after it has been so received into the state are to be considered laws enacted for the purpose of raising revenue for the state, and must conform to the equal protection clause of the Fourteenth Amendment. This conclusion is not only in accord with our previous decisions, but is sustained by the reasoning in a satisfactory judgment of the Court of Errors and Appeals chanroblesvirtualawlibrary
of New Jersey. Erie Railway Co. v. State, 31 N.J.Law, 531, 542-544,.
We thus reach the question whether a tax imposed upon foreign fire, marine, and inland navigation insurance companies on the net receipts of all their business, whether fire, marine, inland navigation, or other risks, is a denial of the equal protection of the laws when domestic insurance companies pay no taxes on such net receipts. Under the previous decisions of the Supreme Court of Illinois, when the net receipts were treated as personal property and the assessment thereon as a personal property tax subjected to the same reductions for equalization and debasement, it might well have been said that there was no substantial inequality as between domestic corporations and foreign corporations, in that the net receipts were personal property acquired during the year and removed by foreign companies out of the state, and could be required justly to yield a tax fairly equivalent to that which the domestic companies would have to pay on all their personal property, including their net receipts or what they were invested in. It was this view, doubtless, which led to the acquiescence by the state authorities and the foreign insurance companies in such a construction of § 30 and in the practice under it. But an occupation tax imposed upon 100 percent of the net receipts of foreign insurance companies admitted to do business in Illinois is a heavy discrimination in favor of domestic insurance companies of the same class and in the same business which pay only a tax on the assessment of personal property at a valuation reduced to one-half of 60 percent of the full value of that property. It is a denial of the equal protection of the laws. Sunday Lake Iron Co. v. Wakefield, 247 U. S. 350, 247 U. S. 352-353; Southern Ry. Co. v. Greene, 216 U. S. 400. Analogous cases are many. Cummings v. National Bank, 101 U. S. 153; Greene v. Louisville R. Co., 244 U. S. 499, 244 U. S. 516; chanroblesvirtualawlibrary
Sioux City Bridge v. Dakota County, 260 U. S. 441, 260 U. S. 445; Taylor v. L. & N. R. Co., 88 F.3d 0; L. & N. R. Co. v. Bosworth, 209 F.3d 0, 452; Washington Water Power Co. v. Kootenai County, 270 F.3d 9, 374.
One argument urged against our conclusion is that the relation of a foreign insurance company to the state which permits it to do business within its limits is contractual, and that, by coming into the state and engaging in business on the conditions imposed, it waives all constitutional restrictions, and cannot object to a condition or law regulating its obligations even though, as a statute operating in invitum, it may be in conflict with constitutional limitations. This argument cannot prevail in view of the decisions of this Court in well considered cases. Insurance Co. v. Morse, 20 Wall. 445; Western Union Telegraph Co. v. Kansas, 216 U. S. 1; Terral v. Burke Construction Co., 257 U. S. 529; Fidelity & Deposit Co. v. Tafoya, 270 U. S. 426; Frost v. Railroad Commission, 271 U. S. 583.
The judgment of the Supreme Court of Illinois must be reversed, and the case remanded for further proceedings not inconsistent with this opinion.
