Mr. Justice Harlan
delivered the opinion of the court.
The Western Union Telegraph Company, a corporation of New York, doing business', both interstate and intrastate, in Arkansas, as it had done for many years, brought this suit against O. 0. Ludwig, Secretary of State of Arkansas, for the purpose of obtaining a decree that the statute of that State of May 13th, 1907, entitled "An Act to-permit foreign corpora tions to do business in Arkansas and fixing fees to be paid by all corporations," Acts of Ark., 1907, p. 744, was unconstitutional, null and void, and enjoining the defendant, in his official capacity, from' attempting to revoke, or proclaiming through official newspaper publications that he had revoked, the authority of the plaintiff to do business in Arkansas, or 1-hat it had no right to continue doing business in that State. The plaintiff, in its bill, asked such other and further relief as (ho case might require and as might seem just.
A temporary injunction was issued, and thereafter the defendant demurred and answered at the same time. The demurrer was on these grounds: That the court was without jurisdiction to hear and determine the case, "the same being in effect a suit against the State" by a citizen of another State to prevent the enforcement of one of its criminal or penal statutes; that the facts stated in the bill are not sufficient to constitute a cause of action nor to warrant the relief asked; and that the bill was wholly without equity. The answer denied all the material allegations of the bill.
Subsequently, the plaintiff, by leave of the court, filed an amendment of its bilk To that amendment no answer was made, but all parties being present, the cause was heard, without objection, on the demurrer to the bill. The demurrer was overruled, and the defendant having elected not to plead further, the injunction previously granted was made perpetual. From that order the present appeal was prosecuted.
The above statute, known as the Wingo Act, whose constitutionality is questioned by the plaintiff, is as follows (the italics being ours):
" § 1. Every company or corporation incorporated under the laws of any other State, Territory or county, including foreign railroad and foreign fire and life insurance companies, now or hereafter doing business in this State, shall file in the office of the Secretary of State in this State a copy of its charter or articles of incorporation or association, or a copy of its certificate of incorporation, duly authenticated and certified by the proper authority, together with a statement of its assets and liabilities and the amount of its capital employed in this State, and shall also designate its general office or place of business in this State, and shall name an agent upon whom process may be served. Provided, before authority is granted to any foreign corporation to do business in this State, it must file with the Secretary of State a resolution adopted by its board of directors, consenting that service of process upon any agent of such company in this State, or upon the Secretary of State of this State, in any action brought or pending in this State, shall be a valid service upon said company; and if process is served upon the Secretary of State it shall be his duty to at once send it by mail, addressed to the company at its principal office; and if any company shall, without the consent of the other party to any suit or proceeding brought by or against it in any court of this State, remove said suit or proceeding to any Federal court, or shall institute any suit or proceeding against any citizen of this State in any Federal court, it shall be the duty of the Secretary of State to forthwith revoke all authority to such company and its agents to do business in this State, and to publish such revocation in some newspaper of general circulation published in this State; and if such corporation shall thereafter continue to do business in this State, it shall be subject to the penalty of this act for each day it shall continue to do business in this State after such revocation.
' "§2. Any foreign corporation which shall fail to comply with the provisions of this act, and shall do any business in this State, shall be subject to a.fine of not less than 11,000, to be recovered before any court of competent jurisdiction, and all such fines so recovered shall be paid into the general revenue fund of the county in which the cause of action shall accrue, and it is hereby made the duty of the prosecuting attorneys to institute said suits in the name of the State, for the use and benefit of the county in which the suit is brought, and such prosecuting attorney shall receive as his compensation one-fourth of the amount recovered, and as an additional penalty,- any ' foreign corporation which shall fail or refuse to file its articlés of incorporation or certificate as aforesaid, cannot make any contract in this State which can be enforced by it either in law or in equity, and the complying with the provisions of this act after suit is instituted shall in no way validate said contract.
" § 3. That all corporations hereafter incorporated in this State and all foreign corporations seeking to do business in this State, shall pay into the treasury of this State for the filing of . said articles a fee of $25 where the capital stock is $50,000 or under; $75. where the capital stock, is over $50,000 and not more than $100,000; and $25 additional for each $100,000 of capital stock.
"Any foreign mutual corporation having no capital stock shall be required to pay to the Secretary of State for filing its, articles of incorporation the sum of $500. Provided, however, nothing in this section shall apply to fraternal orders that write insurance.
" § 4. That Act 185, approved April 17, 1907, and' entitled 'An Act to provide a manner in which' foreign corporations may become domestic corporations and for other purposes,' and all laws and parts of laws in conflict herewith, be and the same are, hereby repealed'; and that this act take effect and be in.force from and after its passage." Acts of Ark. 1907, p. 744.
As the case was decided on demurrer to the bill, the material facts properly alleged are to be taken as true on this hearing. The case made by the plaintiff in its bill is substantially as will be now outlined.
The Telegraph Company was organized in 1851, and immediately thereafter began the work of constructing and operating telegraph lines. Its system extended throughout the United States and Canada, and connected with lines in Mexico and Central and South America by means of submarine cables, and with telegraph systems of foreign countries'.
Among the lines so constructed and forming a component part of the company's system and connecting with its main . office in New York, are lines within Arkansas, most of which were constructed since 1867, in which year the company accepted the terms and conditions of the act of Congress of July 24th, 1866, entitled "An act 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." 14 Stat. 221, c. 230; Rev. Stat., § 5263 to 5269 inclusive.
It should be stated in this connection that, the bill alleges that the company's lines within Arkansas are upon the public domain and upon the military and post roads of the United States, are part of the postal routes and postal establishment' of- the United States', and as such the complainant has under the Constitution and laws of the United States the power and is under obligation to-transmit all messages for the Government and for the public generally, as much and as fully with respect to messages between points'within the said State as interstate messages. ' The company's lines within Arkansas were constructed with the consent and permission of the State, certainly without objection on its part, and in accordance with its laws. The amount which the company, up to the bringing of this suit, had invested in lines within Arkansas was 1153,-000 and continuously since their construction the Telegraph Company has used them "for the transmission of telegraph messages for the Government of the United States, and the several departments thereof, and for the public, as an instrumentality of the Postal Department and of. commerce wholly within the State of Arkansas, and also for interstate commerce and commerce between points in said State and foreign countries, and thus said telegraph lines have been continuously employed in domestic, interstate and foreign commerce since their construction."
The above act of 1907 requires that every foreign corporation doing or seeking to do business in the State should file in the office of the Secretary of State a copy of its charter or articles of incorporation, duly authenticated, together with a statement of its assets and liabilities and the amount of its capital employed in the State, and designate its general office or place of business therein, and the name of an agent upon whom process in any action brought or pending in the State may be served. The company tendered to the Secretary of State a duly authenticated copy of. a resolution of the Board of Directors, assenting to the designation of an agent upon whom process against the company might be served; also, the above required statement; "and offered to the Secretary of State [who claimed to proceed under the above act of 1907] all reasonable fees for the filing and recording of the said papers." But the; Secretary of State refused and still refuses to file the mme unless the Telegraph Company pays to him a fee of $75 upon the first $100,000 of its capital stock, and $25 upon each additional $100,000 of stock. The capital stock'of the Tide-graph Company being $100,000,000, the sum which the Secretary required to be paid as a condition of the company's right to have its articles of incorporation filed, and thereafter to continue doing business within Arkansas without incurring the penalties prescribed by the statute, was $25,050.
We have seen that the act of 1907 provided that if any foreign corporation, without the consent of the other party to any suit brought by or against it in any state court should remove such suit to the Federal court, or institute a suit against a citizen of Arkansas in the Federal court, it became the duty of the Secretary of State, to forthwith revoke all authority in the company and its agents to do business in Arkansas and publish such revocation in some newspaper of general circulation in the State; and if after such revocation the company continued to do any business in Arkansas it became subject to a fine of not less than $1,009for each day it so continued, to be recovered by suits instituted by prosecuting attorneys in the name of the State for the use1 and benefit of the county in which the suit was brought; so, if the company failed to comply with any of the provisions of the act. it became subject to a fine of $1,000; further, if a foreign corporation failed or refused to file, its articles of incorporation, as required, it could not "make any contract " in Arkansas "which can be enforced by it either in law or in equity." Before the bringing of this suit the company had, in fact, instituted a suit in the United States Circuit Court to enjoin the prosecuting attorneys in the several districts of the State from proceeding against it to recover the penalties set forth in the act in question — the suit of Western Union Telegraph v. Andrews &c., this day decided, see p. 1 (55, post.
It is alleged, and the demurrer admits, that the Secretary of State1 has threatened to promulgate, and, unless restrained by order of court, will promulgate, a proclamation that the authority of the company to do business in Arkansas has been revoked and publish the fact of such revocation-in the newspapers, thereby making it appear that the company had become subject to the in-escribed penalties to be recovered in suits brought by the State's prosecuting attorneys, and incapacitated, if the statute be enforced against it, to make any contract in Arkansas, whatever its subject-matter, which is eiiforeible in law or equity.
The- special grounds upon which the statute in question is alleged to be unconstitutional and void may be thus summarized:
1. It imposes upon the Secretary of State the duty — in the event the company instituted a suit in the Federal court against a citizen of Arkansas, or remoyed to the Federal court, without t he consent of the other party, any suit brought by or against it in any court of the State — to forthwith revoke its authority to do business within Arkansas, and subjects the company to the penalty of 81,000 for each day's continuance of such business in-the State after such revocation.
2. If the company fails to file a copy of its articles of incorporation with the Secretary of State, and does not pay, in advance' of such filing, the required fee or tax, based on its capital stock, which represents its property and business everywhere, inside and outside' of the State, it is made liable to a fine of 81,000 for continuing, after such failure,.to do business in Arkansas.
vk As the lines established by the company in Arkansas are practically of no value unless used as the same have been located and constructed, any provision that would prohibit their being used for the purposes and as the same were constructed and designed to be used would deny it the equal protection of the laws and deprive it of its property without due process of law.
4. The State lays an unequal burden. on the plaintiff as compared with, corporations of Arkansas, in that domestic corporations, organized and existing at the time of the passage of the statute, are not required to pay into the treasury of the State any sum whatever upon their capital stock, but are allowed to continue. their business without the payment of any sum; while corporations of other States, even those having lines within the State, under the protection thereof, are required to pay a large tax measured by their entire capital stock, wherever employed, for the privilege of continuing in Arkansas their established and existing business, whether the same be domestic or foreign commerce.
5. Upon the failure of the company to pay the required fee, based on its capital stock employed both within and without the State,, the company is forbidden, or is not allowed, to make any contract within the State, which can be enforced either in law or equity, whether the same relates to domestic, interstate or foreign commerce; whereby, it is alleged, the statute denies to the company the equal protection of the laws, and seeks to er force an illegal exaction for the privilege of using its property for purposes of domestic, interstate and foreign commerce.
6. As the company originally — some thirty or forty years ago — entered the State of Arkansas and constructed and has operated its lines of telegraph, with the consent of the State, and during that period has extended and operated its lines within its limits, with its consent; as the State, from time to time, through legislative enactments, has not only recognized the company's right to transact business within its limits, but regulated its business and affairs; and as, during the above period, with the knowledge and acquiescence of the State, and in reliance upon such license, consent and acquiescence the company has expended large sums of money for the purpose of transmitting messages between the people of Arkansas, the State cannot withdraw its license and expel the company from its limits, even with respect to local business, without impairing the obligation of the company's contract with the State.
Such is the case as made by the bill; and the relief asked is a decree, declaring the statute unconstitutional and restraining any attempt to collect said fee of $25,050, and from imposing any .of the penalties prescribed by it or by any provision therein (except the one requiring the designation of an agent upon whom process may be served in any suit, brought against the Telegraph Company) and enjoining the defendant from attempting to revoke, or from proclaiming that he has revoked, its authority to do business in Arkansas.
The first contention of the appellant that this action is one against the State within the meaning of the Eleventh Amendment of the Constitution, declaring that the judicial power of the United States shall not extend to any suit in law or equity against a State by a citizen of another State. This contention must be held untenable on the authority of Western Union Telegraph Company v. Andrews &c., this day decided. See p. 165, post.
But the vital question in the case is as to the constitutionality of the Arkansas statute. It is insisted by the defendant, among other grounds, that the provision in the statute requiring a foreign corporation, seeking to do business in the State, to pay a fee based upon the amount of its capital stock, for filing with the Secretary of State its articles of incorporation or association is a device which, in effect and by its necessary operation, under the guise of regulating intrastate business, imposes a tax on the • interstate business of such corporation, as well as a tax on its property used and permanently located outside of the State.
.Interpreting it according to the ordinary acceptation of its words, the statute does not discriminate between corporations engaged in interstate commerce and corporations whose business is intrastate in its character, so to make it clear that the State has not assumed to regulate or burden interstate business. Its words are unqualified and are made applicable to . " every company or corporation incorporated under the laws of any other State, Territory or county, including foreign railroad and foreign fire insurance and life insurance, now or hereafter'doing business in this State." §1. "Any foreign corporation which shall fail to comply with the provisions of this act and shall do any business in this State," etc. § 2. "All corporations hereafter incorporated in this State and all foreign corporations seeking to do business in this State," etc. According to the words of the statute, not unreasonably construed, every corporation of another State, seeking to do business in Arkansas, whether interstate or domestic, in order that it may do business of any kind in Arkansas, without coming into conflict with the statute, must file a copy of its authenticated charter with the Secretary of State; and it seems that before that officer will file such copy the corporation must pay to him a given amount based upon its capital stock, representing, necessarily, all its business, interstate and intrastate, as well as all its property everywhere, beyond as ivell as within the State. If the foreign corporation, without first paying those amounts, does business of any kind in the State it will incur not only the penalty of $1,000 for so doing but will'forfeit its right to make any contract in the State,, enforcible'in law or equity — whatever its subject-matter — even if .it be one relating to the business of the United States or to commerce among States. A statute of that kind would be palpably in conflict with the Constitütion, and, especially an invasion of rights under that instrument of a corporation engaged in interstate commerce and seeking to do business in Arkansas.
But, it is said, that the statute in question should not be-so broadly construed. The reasons given for this contention are these: Before the statute here in question was passed there was in force in Arkansas a statute (act of February 16th, 1899, as amended by the act of May 8th, 1899, Kirby's Dig., chap. 31) which was very similar, in many respects, to the act of 1907, now under examination. The state Supreme Court had occasion to determine the scope and effect of that act of 1899. Its decision was handed down March 18th, 1907, while the Legislature of Arkansas was in session, and on the same day another decision was rendered holding material parts of that act to be repealed. Western Union Tel. Co. v. State, 82 Arkansas, 302; Same v. State, 82 Arkansas, 309. These decisions, as counsel suggest, virtually left the State without any'statute prescribing fees to be paid by foreign corporations. Thereafter, on May 13th, 1907, the Legislature passed the statute here in question, known as the Wingo Act, which, with slight exceptions not necessary to be mentioned, was substantially like the act of 1899. The Supreme Court of the State, in Western Union Tel. Co. v. State, 82 Arkansas, 309, 314, construing the above act of 1899, had held that it was its duty, unless otherwise compelled by the plain, ordinary meaning of the words of a statute, to reject any construction that would bring it into conflict with the Constitution of the United States, Grenada County v. Brogden, 112 U. S. 261; Cooley's Const. Lim., § 218; Atty. Gen. v. Electric Storage Battery Co., 188 Massachusetts, 239; that it was too well settled to admit of debate, that "it is beyond the 'power of the State under the guise either of a license tax or police regulation to impose burdens upon interstate commerce or to deny a foreign corporation the right to engage in such commerce in the State" — citing Leloup v. Port of Mobile, 127 U. S. 640; Crutcher v. Kentucky, 141 U. S. 47; and Brennan v. Titusville, 153 U. S. 289. Its conclusion, iri'that case, was that the act of 1899 "must be construed to have been intended only to impose terms upon the right of a foreign corporation to carry on mirastate business and it was a valid statute." Now, the argument at the bar was that when the Wingo Act was passed, the Legislature must be deemed to have had in mind'the judicial construction given to the previous act of 1899, and that it must be assumed that the same court would adhere to its already expressed Views; so, that if a case ever came before it hereafter that involved the meaning and scope of the Wingo Act, expressed substantially in the same words as the act of 1899, the court would construe the Wingo Act, as it construed the act of 1899, as intended only to apply to intrastate business, and not as having been enacted for the purpose of burdening or imposing illegal terms for the transaction of interstate business by foreign corporations in Arkansas.
But the acceptance of this view would not remove the .difficulty which confronts the State in the present case. According to well-settled rules of statutory construction, the validity of a statute, whatever its language, must be determined by its effect or operation, as manifested by the natural and reasonable meaning of the words employed. Henderson v. Mayor, 92 U. S. 259, 268. If a statute, by its necessary operation, really and substantially burdens the interstate business of a foreign corporation seeking to do business in a State, or imposes a tax on its property outside of such State, then it is unconstitutional and void, although the state Legislature may not have intended to enact an invalid.statute. But even if we should assume that the state court would construe the statute of 1907 as intended not to apply to interstate commerce but only to local or intrastate business, wé are, nevertheless, informed by its decision in Western Union Tel. Co. v. State, 82 Arkansas, 302, 318, that, in the opinion of the state court, the statute so construed is valid, and therefore the Telegraph Company, in order that it may safely continue local business in Arkansas, must first pay into the treasury of the State certain amounts based on its entire capital stock for simply filing its articles of incorporation with the Secretary of State; and if it does not pay the specified fees, ba^cd on its entire capital stock, and yet continues to do intrastate busi ness in Arkansas, it will incur the prescribed penalty of one thousand dollars for continuing to do business in the State, and, in addition, lose its power or right to make any enforcible contract in the State. These are, in effect, conditions upon which the Telegraph Company; lawfully engaged in interstate business, and entitled to be in Arkansas for such business, is permitted to enter the Stat'e to do local business within its limits. And these conditions have been prescribed, notwithstanding the company has been .permitted for many years, long before the act here in question was passed, to do local business in the State with its permission and acquiescence, and has invested there large sums of money in preparing to serve the public efficiently in that kind of business. The capital stock of the company represents, we.repeat, all its business, property and interests throughout the United States and foreign countries, and the requirement that the company, engaged in interstate commerce, may continue to do a local business in Arkansas, and escape the heavy- penalties prescribed, must pay a given amount (in this case $25,050), based on all its capital stock, merely for filing its articles of incorporation with the Secretary of State, is, in effect, a direct burden and tax on its interstate business, as well as on its property outside of the State. The case cannot be distinguished in principle from Western Union Tel. Co. v. Kansas, ante, p. 1, and Pullman Company v. Kansas, ante, p. 56, recently decided. The difference in the wording of the Kansas and-Arkansas statutes cannot take the present case out of the ruling of the former cases. On the authority of the Kansas cases, and for the reasons- stated in the opinions therein, we hold the statute in question to be unconstitutional and void, as illegally burdening interstate commerce and imposing a tax on property beyond the jurisdiction óf the State.
Whether the statute of Arkansas is, in any particular, vio-lative of the constitutional guaranty securing the equal pror tection of the laws, or of the guaranty prohibiting the deprivation of property, except by due process of law, or of any other constitutional guaranty, it is not necessary' now to consider. What1 has been said is sufficient for the determination of the present case, and wc do not at this time go further than is indicated in this opinion. Suffice it to say that the defendant threatens to issue, in his official capacity, and publish, in the newspapers, a proclamation to the effect — no matter- upon what specific grounds — that the Telegraph Company is not authorized, but is forbidden, under penalty, by the laws of Arkansas, from continuing to do local business in' that State. Such a proclamation, which the court, as well as every one else, must know, would not only produce confusion in and irreparable damage to the company's business in Arkansas, but would, in effect, declare that the company is not only subject to a prescribed penalty of $1,000 for continuing to' do local business in Arkansas, but is forbidden to make any contract whatever in that State that is enforciblc in law 'or equity. In order to prevent the contemplated or threatened -injury to the company the court below properly made a decree, perpetually enjoining the appellant, as Secretary of-State, his agents and attorneys, from making proclamation that the Telegraph Company has no authority to corn tinue doing business in Arkansas.
Mr. Justice Moody heard the argument of this case, participated in its decision, and concurs in this opinion.
The Chief Justice, Mb. Justice McKenna, and Mr. Justice Holmes dissent.
The decree below must be affirmed.
It is so ordered.
