    WESTERN UNION TELEGRAPH COMPANY v. MISSOURI ex rel. GOTTLIEB.
    ERROR TO THE SUPREME COURT OF THE STATE OF MISSOURI.
    No. 256.
    Argued April 21, 1903.
    Decided May 18, 1903.
    1. In estimating, for purposes of taxation, the value of the property of a telegraph company situate within a State, it may be regarded not abstractly or strictly, locally, but as a part of a system operated in other States; and the taxing State is not precluded from taxing the property because it did not create the company or confer-a franchise upon it, or because the company derived rights or priviliges under the act of Congress of 1866, or because it is engaged in interstate commerce.
    Where the highest court of a State has decided that the board of equalization has acted according to the methods prescribed and authorized by the iaws of the State and that an order made.by it is legal under the state constitution and statutes, the decision constitutes an interpretation of the law of the State and is not open to dispute in this court.
    2. Proceedings before a board of equalization are gttasi-judicial, and if an order- made by it is within its jurisdiction, it is not void and cannot be resisted in an action at law; nor can overvaluation be made a ground of defence at law. The action of the tax officers being in the nature of a judgment must be yielded to until set aside. And this can only be done . in a direct proceeding.
    The defendant in error is the tax collector of.Jackson County, Mo., and brought this action against the plaintiff in error in the Circuit Court of that county for the sura of $1027.22, the taxes assessed against plaintiff in error for the year 1899, apportioned to Jackson County. The answer of the plaintiff in error alleged illegality in the taxes upon two groundsFirst, that the taxes were levied upon the franchis.e of the plaintiff in error, derived from the United States under certain acts of the Congress; second, that the state board of equalization, intending to injure the plaintiff by compelling it to pay an excessive and disproportionate share of state and local taxes, assessed its pqles, wires and instruments at far more than their actual value.
    The plaintiff in error is a telegraph company, incorporated by the State of New York. It does business in the State of Missouri, having offices in a. number of cities of that State, and its lines run between those cities and to and from them to other places in the Union ; in other words, the plaintiff in error engages in intrastate and interstate business. It claims-t'o have no franchises from the- State of Missouri, (except in an unimportant instance,) but occupies the streets-of its cities, and its public roads and highways, by authority of the act of Congress of July 24, 1866, entitled” Anact to aid in the construction of telegraph lines, and to secure to the government the use of the same for postal, military,' and other purposes.” The material part of section one of the act is as follows : ■
    “ SeCtxoN 1. That any telegraph company now.organized, or which may hereafter be organized under the laws of any State in this Union, shall have the right to construct, maintain, and operate lines of telegraph through and over any portion of the public domain of the United States, over and along any of the military or post roads of tbe United - States which have been or may hereafter b.e declared such by act of Congress, and over, under, or-across the navigable streams or waters of the United States: Provided, That such lines of telegraph shall be so constructed and maintained as not- to obstruct the navigation of such streams and waters, or interfere with the ordinary travel on such military or post roads.”
    Section two provides that the messages between the officers and agents of the government shall have priority; and be sent at rates to be fixed by the Postmaster General.
    Section three -forbids the transfer of the rights conferred by the act.
    Section four gives the United States the power to purchase the telegraph lines, property and effects of any. company availing itself of the benefits of the act.
    Section four is as follows:
    
      “And be it further enacted, That.before-any telegraph company shall exercise any of the powers or privileges conferred by this act, such company shall file their written acceptance with the Postmaster General of the restrictions and obligations required by this act.”
    Under the constitution and laws of Missouri, the state board of equalization, composed of the governor, secretary of state, state auditor, state treasurer and attorney general, assesses railroad and telegraph property, and it also equalizes the real and personal property assessed by the local assessors. .Exercising its powers of oi’iginal assessment, the board made the following order in regard to the property of plaintiff in error:
    “ State of Missouri, office of state auditor.
    “ Be it remembered that heretofore, to wit, on the twenty-fifth day of July, 1899, the following, among other proceedings, were had by the state board of equalization, viz.:
    
      “ The state board of equalization having given to the Western Union Telegraph Company opportunity to be- heard personally by the board, and having heard the said company, through its officers and agents, and having carefully considered the facts set out in the returns and the statements of said company, and all evidence of value, and all matters bearing upon the question of the value of the property of said company, and considering the cost of construction and equipment'of said Western Union Telegraph Company, and the location thereof, and its traffic and business, and the market and ‘par value of its stocks and bonds, and the gross receipts and net earnings and franchise owned by said company, and the value thereof, and having received evidence concerning the value of the cost of construction of said telegraph line, and the market value and par value of the stocks and bonds, and the gross receipts and net earning power, and the franchise and value thereof, and having heard evidence upon and considering all other matters ascertainable by said board bearing upon the question of the value of said company, which, in the opinion of the board, would assist in its findings, conclusions and judgment in arriving at the actual cash value of the property of said telegraph company; on motion the state board of equalization assesses and values for taxes of 1899 the property of said Western’ Union Telegraph Company at $1,827,727.45; and it is further ordered by the state board of equalization that the assessed value, thereof be distributed upon the classes of property as follows
    6075.98 miles of poles at $71.50 per mile . $434,432 57
    23,767.34 miles of wire at $22.02 per mile . 523,356 82
    .3375 instruments at $5.70 each : . . 13,537 50
    All other property at. . . . . 856,400 56
    $1,827,727 45”
    The apportionment of the tax to Jackson County was as follows:
    For state purposes . -.$202 43
    For county purposes. 283 40
    For road purposes . . . . . 35 41
    For general county school purposes . . 370 61
    For school building purposes.- 2 98
    For other school purposes : . . . .19 03
    For Kansas City municipal purposes . . 81 21
    For Independence municipal purposes . . 25 38
    For Kaw township railroad purposes . . 2 03
    For Blue township railroad purposes . . - 4 74
    Total $1027 22
    
      The case ivas tried without a jury and the trial court found “the fact to be from the evidence and the pleadings that the defendant owned in the State of Missouri, at the túne of said assessment, the poles, wires and instruments of the value herein-before set forth. And the court finds the fact to be from the evidence that in valuing ‘ all other property ’ of defendant the state board took into coiisideration the franchise of defendant company, and the court finds under the law, and so declares, that the franchise of defendant .company is not subject to valuation and taxation, and as to this item of the above-named valuation the court finds the issues for the defendant.”
    Judgment was entered against plaintiff in error in the sum of $605.82, being the tax on the poles, wires and instruments of the company, with interest at two per cent for collectors’ fees, and also for an attorney’s fee. The amount found due was made a first lien against the property of defendant in error, and special execution ordered to be issued. Both parties moved for a new trial, which motions were denied. Both parties then appealed to the Supreme Court of the State, which court reversed the judgment of the Circuit Court. After an elaborate discussion of the case the Supreme Court said:
    “It follows that the judgment of the Circuit Court holding that the tax assessed against ‘ all other property at $856,400.56 ’ to be unlawful, is'erroneous, and that the plaintiff is entitled to a judgment for the whole amount of the tax sued for. Judgment is accordingly entered, here, for the plaintiff, for $1027.22, back taxes for the year 1899, with interest thereon from the first of January, 1900, at the rate of orre per cent per month, Rev. Stat. 1899, sec. 9225, and costs.” 165 Missouri, 502.
    This writ of error was then sued out. Other facts appear in the opinion.
    
      Mr. John F. Dillon and Mr. Eleneious Smith, with whom Mr. Alexander New and Mr. Henry D. Estabrook were on the brief, for plaintiff in error.
    I. The Western Union Telegraph Company is an agent of the government and an instrument of interstate commerce; and its franchises exercised in Missouri having been derived solely from, the Federal government are exempt from taxation by the taxing authorities of the State.

    II. The state board of equalization has discriminated against plaintiff in error and in favor of other persons generally. The board, in order to discriminate as aforesaid, fixed the value of the property of the Western Union Telegraph Company for taxation at far more than its full actual cash value and intentionally equalized and adjusted the values of other property throughout the State at 40 per cent of the actual cash value thereof. The necessary effect .of all of which has been that the said company has been discriminated against in violation-of the Fourteenth Amendment to the Constitution of the United 'States. Pelton v.

    III. Where discrimination of the character mentioned under point II exists, it amounts to fraud in law and a denial of the equal protection of the law and the courts will grant relief. Likewise where lack of jurisdiction to make the assessment is shown. . Authorities under point II, and State ex rel. v. Yaile, 122 Missouri, 33; State ex rel. Love v.

    IY. In all Cases where franchises such as those possessed by the Western ITnion Telegraph Company have been considered in estimating the value of property assessed and. such assessments have been sustained, statutes providing for the assessment of corporations under a “ unit ” system have contained express and detailed provisions for correctly ascertaining the valuation of the property to be assessed. No such provisions are found in the laws of Missouri. The “ ways and means ” for any such assessment have not been prescribed. Furthermore, the statutes of Missouri exclude any such mode of assessment of telegraph companies. West. U. Tel, ■ Co'.y. Massa

      Mr. Hunter M. Meriwether, with whom Mr. Robert E. Ball was on the brief, for defendant in error.
    I. The franchises, in the sense of intangible property, as well as the poles and wires of the Western Union Telegraph Company,, are taxable by the several States. Such franchise taxes have been sustained in all recent cases by the' Supreme Court of the United States against this defendant, and others similarly situated. Western Union Tel. Co. v. Massachusetts,. 125 U, S. 530,' Massachusetts v. Western Union Tel. Go., 141 U. S. 1-40; Central Pacific Ry. Co. v. California, 162 U. S. 91; Western Union Tel. Co. v. Norman, 77- Fed!

    II. The assessment made by the- state board was an assess-, ment of the' property of plaintiff in error, and did not include or in any way affect- the right to exist and transact its business' in- Missouri or elsewhere. The tax is strictly a property tax, and having been fairly and legally assessed upon a reasonable v valuation of the property, should be sustained. National Bank v. Commonwealth, 9 Wall, -353; Railroad Co, v. 
      Peniston, 18 Wall. 5, loe. eit. 30 ; Commercial Electric Light Co. v. Judson, 56 Pac. Rep.' (Wash.) 829; Louisville By. Co. v. Commonwealth, 49 S. W. 486; Paducah St. By. Co.v.

    III. There is a clear distinction between a license tax and a property tax. The former involves a charge for permission or authority to transact certain business, while the latter is a contribution imposed upon, and measured by the property of an individual or. corporation. The State cannot impose a license, impost, or embargo on plaintiff in error, even though it be’ called a tax. But it can take from the property owned by plaintiff in error within the jurisdiction of' the State, a sufficient amount to. pay its just proportion pf its governmental expenses.' Nothing else having been attempted the tax should, be sustained.

Eminent, 103 Missouri, 241 ; Eminent v. Missouri, 156 U. S. 296.

   Mr. Justice McKenna,

after stating the facts, delivered the opinion of the court.

1. On the question of fact, if it be such, as to what constituted the item' “ of other property at $856,400.56,” -in the assessment by the board of equalization, the trial court and the Supreme Court of the; State, are riot in accord. The trial court found the “ fact to.be from the evidence that in'valuation of other property ’ of defendant, .the' state board took into consideration the franchise of defendant company.” It is apparent from the court’s opinion that by franchise the court meant the rights and privileges obtained by the plaintiff in error under the act of Congress of July 24, 1866.- The Supreme Court of the State, however, expressed, its conclusion from the evidence, as follows:

“So that, when, in determining the value of the property of the defendant in this State,.the board of equalization took into considerationthe cost of construction and equipment of said Western Union Telegraph Company, and the location thereof, and its traffic and business, and the par value of its stock and bonds, and the gross receipts and net earnings, and franchises owned by said company, and the value thereof,’ it did. riot and could not have included therein any franchise derived by the defendant from the government of the United States, because-' that government had conferred no such franchise; nor-was such a valuation placed upon ‘ all other property,’ a tax upon the franchise of-the defendant company. The franchise derived by the defendant from the State of -New York was-considered by the board in determining the value of the property ¡ of the defendant- located in this State: - That is, that property -was valued, not as so many poles, so much wire, so many instruments or so much ‘ other property ’ in the abstract, but w§is valued -in the concrete,' in the relation that such property in the abstract bore to other property in the abstract, which being brought into relation - towards each other — into a system, located partly in, this State and partly in Other States — gave each part - a concrete value, which was much greater. than its abstract value: The right to exist — the franchise — of -the defendant was property;, and was subject to taxation, either directly,- in the proportion that the portion of the franchise exercised in this State bore to the proportion of the franchise exercised in all other States, or indirectly, as was doné in Massachusetts and as was done here, by being impressed upon- the tangible property owned by it, thereby increasing its value, and by considering the franchise and its tangible property as a system, and then assessing the part of the property. forming a part of the system and located in Missouri as of its proportionate value of the whole'property constituting the system.” ■

Plaintiff in error asserts the correctness of the finding of the trial court, and insists that it is the only finding that could have been made, and bases the argument against the taxes assessed on that insistence. But- if the finding on the question is one of fact, necessarily we are bound by that m^de by the Supreme Court of the State.. The trial court picked' out the rights given to the defendant under the act of Congress, denominated them a franchise,' contemplated the franchise as a distinct' proprietary, entity, and, becauseit was derived from the Federal government, decided that it was exempt from' taxation.. The necessary consequence was and is to destroy the relation between that franchise and the other, properties of the plaintiff in error, regarding them, not as parts.of the system, but abstractly — regarding the poles not differently from other poles, the wire not differently from other wire. The Supreme Court, on the contrary, regarded the-properties as related and as constituting a system, and because of their relation, having a value greater than the sum of the values of the individual things regarded merely as such. Viewing the order of the board of equalization, as the Supreme Court viewed'it, was it valid ?■ In other words, is the State in exercising its taxing power limited to assessing the mere material things used by the plaintiff in error, and must it regard them as of no greater value than they had when they reposed in lumber yards' and factories, with cost added of putting them in place ? Or the proposition may be stated another ■way, which better expresses the ultimate contention of the plaintiff in error. • Conceding.that the tangible property of the telegraph company derives value from its use in a system,, does the company do business in the State in pursuance of the Constitution of the United States and the act of. July, 1866, and become thereby an instrument of interstate commerce and a government agent, and as such exempt from the taxation contested in this case ? "We think the question has been answered by this court.

In Western Union Telegraph Co. v. Massachusetts, 125 U. S. 530, the effect of the act of July, 1886, upon the power of the State to tax the property of telegraph companies was considered. The laws of Massachusetts imposed a tax upon the Western Union Telegraph Company on account of the property owned and used by it within that State, the value of which was ascertained by comparing the length of its lines within the State with the length of its entire lines; The tax was sustained. The act of July, 1866, was urged against the tax as it is urged here. •

The contention of the company in that case was, as it is in this, that it did not derive its existence from the taxing State but from the State of New York; that it did not do business in the taxing State by permission of that State, but by. virtue of heing an instrument of interstate commerce; that its rights and privileges and franchises were conferred by the United States and constituted it an agent of the United States, and as such agent it was-exempt from the tax imposed. The contentions were rejected. The court did not test or measure the power of the State by the name which its laws gave the tax, and, speaking by Mr. Justice Miller, said :

“ The argument is very much pressed that it is a tax upon the franchise of the company, which franchise being derived from the United States by virtue of the statute above recited cannot be taxed by a State, and counsel for appellant occasionally speak of the tax authorized by the law of Massachusetts upon "this as well as all other corporations doing business within its territory, whether organized under' its laws or not, as a tax upon their franchises. But by whatever name it may be called, as described in the laws of Massachusetts, it is essentially an excise upon the capital of the corporation. The laws of that Commonwealth attempt to ascertain the just amount which any corporation engaged in business within its limits shall pay as a contribution to the support of its government upon the amount and value of the capital so employed by it therein.*’

And that power of the State was explained in an elaborate opinion and sustained. These propositions were laid down: That the company owed its existence as a corporation and its right to exercise the business of telegraphy to the laws of the State under which it was organized; that the privilege of running the lines of its wires over and along the military and post roads of the United States was granted by the act of Congress, but that the statute was merely permissive and conferred no exemption from the ordinary burdens of taxation ; that the State could not by any specific statute prevent a corporation from placing its lines along the post roads or stop the use of them after they were so placed, but the corporation could be taxed in exchange for the protection it received from the State “ upon its real or personal property as any other person would be.” And describing the particular tax imposed it was said:

“ The tax in the present case, though nominally upon the shares of the capital stock of the company, is in effect a tax upon that organization on account of property owned and used by it in the State of Massachusetts, and the proportion of the length of its lines in that State to their entire length throughout the whole country is made the basis for ascertaining the value of that property; We do not think that such a tax is forbidden by the acceptance on the part'of the telegraph company of the rights conferred by section 5268 of the Revised Statutes, or by the commerce clause of the Constitution.”

In other words, the lines in Massachusetts were regarded as a part of a system and assessed accordingly.

The statute of Massachusetts came up again for consideration in Massachusetts v. Western Union Telegraph Co., 141 U. S. 40, and the principles announced in Western Union Telegraph Co. v. Massachusetts, supra, were affirmed and followed. See also Ratterman v. Western Union Telegraph Co., 127 U. S. 411; Leloup v. Port of Mobile, 127 U. S. 640.

These eases establish that in estimating the value of the property of a telegraph company situate within a State it may be regarded not abstractly or strictly locally, but as a part of a system operated in other States, and that the State was not precluded from taxing the property because the State had not created the company or conferred franchise upon it, or because it derived rights or privileges under the act of July, 1866, or was engaged in interstate commerce. Every one of the fundamental propositions,- therefore, contended for by plaintiff in error, those decisions declare unsound.

But it is contended that the method of assessment followed in those cases was sustained because they were prescribed by the legislature, and that in the case at bar the method adopted was not prescribed or authorized by the laws .of-Missouri. The -answer is obvious. What the laws of Missouri authorized was competent for the Supreme Court of Missouri to decide,.and it decided that the.order of. the board of equalization was legal under the constitution and statutes of th,e State. ' The decision, constituting as it does an interpretation of the constitution and laws of the State, is not open, to dispute here. If it were, it would seem incontestable that the State" could either prescribe; the method of confer upon its taxing officers the power to adopt a suitable one. And there is nothing in the Adams Express Company cases, 166 U. S. 171; 166 U. S. 185, 226, to the contrary.

2. The plaintiff in error asserts that the board of equalization practiced discrimination against Jt by assessing at a value disproportionate to the value assessed on real and personal property by local assessing officers. This defence was expressed as follows:

“ Defendant avers that under the law it was the duty of said board, of equalization to adjust and equalize as aforesaid the valuation of all real and personal property.in the State of Missouri, among the several counties in the State, and that during the period aforesaid it did so proceed to adjust and equalize such valuations. That said state board of equalization, by common arrangement, understanding and purpose among themselves, in fact- did, during the period aforesaid, in violation of the constitution and laws of said State of Missouri, with intent to compel defendant to pay a greater proportion of taxes than the owners of other real and personal property in said State of Missouri, assess all property, to wit, other than the property of the telegraph companies, to wit, from thirty-five to forty per cent of its true value, whereby as to taxes levied upon real and personal-property other than telegraph property in the State of Missouri, this defendant was unlawfully and wrongfully discriminated" ■against to the extent of sixty per cent of the amount of-taxes assessed by said state board of equalization and levied'by the taxing officers of the State, upon defendant in pursuance of such assessment.”

Testimony was introduced to sustain the averments.

The Supreme 'Court of Missouri held, however, that plaintiff in error could not, even under the casés cited by it, avail itself ■of the defence. The court said:

“The defendant cannot avail itself of these cases,- for the Reasons, first, that it seeks to raise the question of discrimination by a defence to an action at law to collect the taxes, and thereby collaterally attacks the judgment of the board of equalization; second, that such questions can only be raised by a, direct attack, in equity, and then only upon the condition precedent that it pays or tenders the amount justly due and only asks to have the collection óf the excess restrained. This’ the defendant has not done in this case. -It simply alleges a discrimination or excessive tax, and then seeks to defeat the whole assessment without paying or tendering, anything, notwithstanding’ it admiffi by its answer and its proofs that it has property in this State subject . to taxation of the value of $541,412.40.' Upon the' authority of the cases relied on by it, this-cannot be done.” ■

We concur in this view. The proceedings before’the board were quasi judicial, and the order made by it was within, its , jurisdiction. , It was notvoid on its face; and cannot be resisted /in an action at law. This is the principle announced in the case referred to. In Stanley v. Supervisors of Albany, 121 U. S. 535, is cited, among other cases, Balfour v. City of Portland, 28 Fed. Rep. 738. The case is especially pertinent. The action was at lawfor the recovery of .taxes paid under protest which had beén. levied upon property, which, it was charged, - had been- deliberately overvalued. Recovery was denied. The Circuit Court said:

"The property\was subject to taxation by the authority and for the purpose alleged: True, the result reached was erroneous, - because of the- willful disregard in the proceeding of the law requiring uniformity in the. valuation of property for taxation within the jurisdiction of the defendant. Still, the proceeding being quasi judicial, and .the subject matter within the jurisdiction of the officers who' conducted it, the result reached is so far conclusive that the legality*of it cannot be questioned in an action at lavv to recover back the one half of the tax as illegal.”

So this court said in Stanley v. Supervisors, supra:

“ It is only where the assessment is wholly void, or void with respect to separable portions of the property, the amount collected on which is ascertainable, or where the assessment has been set aside as invalid, that an action at law will lie for the taxes paid, or for a portion thereof. Overvaluation of property is not a ground of. action at law for the excess of taxes paid beyond what should have been levied upon a just valuation. The courts cannot, in such cases, take upon themselves, the functions of a revising or equalizing board. Newman v. Supervisors, 45 N. Y. 676, 687; National Bank of Chemung v. Elmira, 53 N. Y. 49, 52; Bruecher v. The Village of Portchester, 101 N. Y. 240, 244; Lincoln v. Worcester, 8 Cush. 55, 63; Hicks v. Westport, 130 Massachusetts, 478; Balfour v. City of Portland, 28 Fed. Rep. 738.”

And we think overvaluation of property cannot be a ground of defence at law. In other words, the action of the tax officers, being in the nature of a judgment, njiust .be yielded to until set aside. This can oniy be done in a direct proceeding. The property owner is in effect a plaintiff, and the condition of relief against the enforcement of the quasi judicial order, which he. attacks, is a tender of payment of the taxes that he ought to pay. And this condition would still be upon him if he set up overvaluation as an' equitable -defence to an action brought against him. County of Los Angeles v. Ballerino, 99 California, 593, 597. This certainly would be so in Missouri, under the doctrine expressed by the Supreme Court of thfe State in the. case at bar.
