Mk. Justice Holmes

delivered the opinion of the court.

This is a suit brought by the defendants in error to prevent the Railroad Company, plaintiff in error, from moving its machine shops, roundhouses, and general offices from the City of Palestine and from maintaining any of them elsewhere. An injunction was issued as prayed; the judgment was affirmed by the Court of Civil Appeals, 174 S. W. Rep. 305, in accordance with intimations of the Supreme Court of Texas at an earlier stage, 106 Texas, 60, and an application to the latter Court for a writ of error was refused. The case'is brought here upon voluminous assignments of error which may be summed up in the propositions that the state court was without jurisdiction because of certain foreclosures in the Courts of the United States, that the judgment disregarded rights secured by the decrees of those Courts, and that it gave effect to a statute which as applied burdened interstate' commerce, impaired the obligation of contracts, etci, and was contrary to Article I, §§ 8 and 10, and to the Fourteenth Amendment of the Constitution of the United States.

The facts begin with the predecessors of the plaintiffs in error. The Houston and Great Northern Railroad Company, a local road, was chartered by a special Act *429 on October 26, 1866. About March 15,1872, it contracted with the citizens of Palestine in the County of Anderson in consideration of the issue of bonds by the county to maintain its general offices, machine shops and roundhouses at that place. The International Railroad Company was chartered in like manner on August 5, 1870. In 1872 the two companies agreed to consolidate and this agreement was ratified by the stockholders of each in 1873. A special Act.of April 24, 1874, authorized the consolidated company, known as the International and Great Northern Railroad Company, to issue bonds secured by mortgage and provided that all acts theretofore done in the name of either of the companies should be of the same binding effect upon the new one that they were upon the old. In 1875 the new company in consideration of the erection of houses for its employees renewed the contract of the Houston & Great Northern and at about the same time it resolved that its general offices should be removed to Palestine. We see no reason for reopening the findings below that the alleged contracts were made. The offices were removed and there they remained, subject to some immaterial interruption, until 1911. The machine shops and roundhouses are still there. Each of the two constituent companies had, executed mortgages before the date of the original agreement of the Houston & Great-Northern and each executed another before the contract of the consolidated company ip 1875. These mortgages were all foreclosed in 1879. and the property conveyed to a corporation, still called the International & Great Northern Railroad Company, by a deed that conveyed all the franchises and chartered powers of the original roads: The foreclosure is one fact relied upon for the defence.

The purchasing company in its turn executed mort-. gages, one of which, including, like the earlier ones that we have mentioned, the franchise to be a corporation, *430 dated in 1881, is the source of the plaintiff in error’s title, by a foreclosure in 1910-1911, Before this last foreclosure took place two statutes were enacted in Texas that are important. The first, known as the Office-Shops Act, approved March 27, 1889, c. 106, Rev. Civil Stats. 1911, § 6423, provided that every railroad company chartered by the State or owning or operating a line within the State should permanently maintain its general offices at the place named in its charter, and if no certain place were named there, at such place as it should have contracted to locate them, otherwise at such place as it should designate; also that it should maintain its machine shops and roundhouses at the place where it had contracted to keep them, and that if the offices, shops or roundhouses were located on the line of a railroad in a county that had aided such railroad by an issue of bonds in consideration of the location being made, then such location should not be changed; “and this shall apply aa well to a railroad that may have been consolidated with another as to those which have maintained their original organization.” A violation of the act entails forfeiture of the charter, with a penalty of $5,000 a day for every day of violation. Rev. Stats., § 6425. An act approved two days later, March 29, 1889, with provisos that no rights should be acquired inconsistent with the present constitution, that the main track once constructed and operated should not be removed, &c., authorized purchasers of sold-out railroads to form a new corporation, whereas previously the purchaser had continued the franchises of the old under the original grant. A law of September 1, 1910, c. 4, further emphasized the change of policy by excluding a succession to the old charter unless coupled with an acceptance of certain liabilities, and providing that the charter should pass subject to the provisions and limitations imposed and to be imposed by law. Rev. Stats., § 6625.

*431 The mortgage of 1881 last mentioned was foreclosed by proceedings in the Circuit Court of the United States. A decree of May 10, 1910, while reserving jurisdiction of the property, ordered a sale, which, after, postponements, took place on June 13, 1911, and was confirmed the next day. On September 25, 1911, the railroad and franchises were finally discharged from the possession and control of the receiver and the Court. Before that date the plaintiff in error was incorporated under the Act of 1889 and general laws and took the conveyances under the foreclosure decree. Within the time allowed it had filed in Court a repudiation of any agreement on the part of any of its predecessors to maintain their offices and shops at Palestine, ,and later gave notice to that effect to officials of Anderson County and Palestine. The articles of incorporation fixed the place for the general offices as Houston.

The railway company denies the jurisdiction of the state court and sets up that the court of the last foreclosure is the only proper forum. But a decree of foreclosure does not render the purchaser and property foreclosed sacrosanct. The Circuit Court had finishéd the case and had given up possession and control before this suit was brought. Shields v. Coleman, 157 U. S. 168, 178, 179. Wabash R. R. Co. v. Adelbert College, 208 U. S. 38, 55. Even if it were true that the foreclosure sale and order carried an immunity from the present demand that the railway was entitled to set up, in the absence of action on the part of the Court of the United States, it would not take away the power of the state court to decide as to the existence of an alleged public duty on the part of a railroad within the territory where the court sat. Ricaud v. American Metal Co., ante, 304.

But the foreclosures did not have the supposed effect. They no more removed all human restrictions than they excluded the authority of ordinary courts. Suppose *432 that a special act incorporating the mortgagor had provided in terms evidently intended to reach beyond foreclosure that the general offices were to remain forever at Palestine, it hardly would be argued, and certainly would not be argued here or in Texas with success, that the requirement could be touched by,a decree. But if the law made that requirement, it hardly matters whether the restriction was imposed by charter or otherwise or whether the remote reason for it was a contract or a general notion of public policy. The state courts hold that when the law on any ground fixes the place of the offices and shops the obligation is indelible by foreclosure. We see no reason why their decision should not prevail.

It is contended that the Office-Shops Act of 1889 does not touch the-plaintiff in error by its terms and that if it be construed to do so it is unconstitutional. On the construction of the act it seems to us that there can be no doubt. It is true that the provision requiring the general offices to be maintained at the place where the railroad had contracted to keep them is conditioned on no place being named in the charter, but of course this does not mean that articles framed under a general law can get rid of contracts that otherwise would bind, and in our opinion it is equally plain that no distinction was intended between the contract by the present road and one by-its predecessor, if the office and shops “are located on the fine of a railroad in a county which has aided said railroad by an issue of bonds in consideration of such location being made.” “Then,” the statute says, “said location shall not be changed.” The construction of the act by the state court is beyond criticism upon this point.

It is said that the act so construed would infringe the constitutional rights of the parties to the mortgage of 1881, which the plaintiff in error took by foreclosure. *433 But it will be. remembered that the mortgagor under the law then in force merely had succeeded to the original contractors, freed from their unsecured. debts, no doubt, but, it well might be held, not freed from the obligati'n in question. Also it was found by the Courts below that the sale under which the mortgagor took in 1879 was not a bona fide sale, and so was not a sale that put the purchaser in a position other than that of mortgagor. Apart from these considerations we should be slow to say that it was not within the power of a state legislature dealing with a corporation of the State to fix the place of its domicile and principal offices, in the absence of other facts than those appearing in this case. But furthermore when the Office-Shops Act was on the statute book the plaintiff in error took out a charter under general laws that expressly subjected it to the limitations imposed by law. It is- said that this does not make the plaintiff in error adopt an otherwise unconstitutional statute. But even if, contrary to what we have intimated, the act could not otherwise have affected those particular corporations, it was a law upon the statute books and was far from, a mere nullity, and if it was made a condition of incorporation that this restriction should be accepted, the plaintiff in error cannot complain. Interstate Consolidated Street Ry. Co. v. Massachusetts, 207 U. S. 79. We agree with the state courts that the condition was imposed.

The acceptance of the charter by the plaintiff in error disposed of every constitutional objection but one. It is said that the restriction imposes a burden upon commerce among the States, since the road concerned has expanded and now is largely engaged in such commerce. The jury found that it imposed no such burden, upon an issue submitted to them in accordance with the desire of the plaintiff in error, although not in the form that it desired. So far as the question depended upon *434 the testimony adduced the verdict must be accepted, and although no doubt there might be cases in which this Court would pronounce for itself, irrespective of testimony, whether a burden was imposed, we are not prepared to say that in this instance the State has transcended its powers. The burden if any is indirect. Some complaint is made of the form of the judgment, as purporting to be perpetual. But the word perpetual adds nothing to a requirement that the office and shops should be 'maintained in Palestine.. The requirement is perpetual until .the law is changed. When and how it may be changed is not before us now. Other objections are urged and other details are adverted to in. the very lengthy printed arguments, besides those with which we have dealt, but we deem it unnecessary to -go farther. Upon the whole case we' are of opinion that the judgment below should be affirmed.

Judgment affirmed.
