A motion was filed by the appellant to dismiss the appeal of the paving company, which was postponed to the hearing of these appeals upon the merits. An examination of the motion, and a consideration of the briefs filed and arguments made in support of and in opposition to the same, leads us to the conclusion that it cannot be sustained. The appellant appealed directly to this court; for while there was an allegation of diverse citizenship in the bill, jurisdiction was also invoked on the constitutional grounds above stated. This made the case appealable directly to this court under § 5 of the act of March 3, 1891 ([26 Stat. at L. 827, chap. 517] U. S. Comp. Stat. 1901, p. 549), as one which 'involves the construction or application of the Constitution of the United States.'

The contention is that the prayer of the complainant on the constitutional grounds having been denied, the appeal of the respondent should have been to the circuit court of appeals. But we cannot agree to this view. There was no cross bill filed in the case, and none was required. The bill of complaint contained allegations sufficient to make a case of alleged violation of constitutional rights. It is well settled that in such cases the entire case may be brought to this court by the appeal. In Holder v. Aultman, M. & Co. 169 U. S. 81-88, 42 L. ed. 669-671, 18 Sup. Ct. Rep. 269, discussing the act of March, 1891, Mr. Justice Gray said:

'Upon such a writ of error, differing in these respects from a writ of error to the highest court of a state, the jurisdiction of this court does not depend upon the question whether the right claimed under the Constitution of the United States has been upheld or denied in the court below; and the jurisdiction of this court is not limited to the constitutional question, but includes the whole case. Whitten v. Tomlinson, 160 U. S. 231, 238, 40 L. ed. 406, 410, 16 Sup. Ct. Rep. 297; Penn Mut. Ins. Co. v. Austin, 168 U. S. 685, 42 L. ed. 626, 18 Sup. Ct. Rep. 223.' Loeb v. Columbia Twp. 179 U. S. 472, 45 L. ed. 280, 21 Sup. Ct. Rep. 174.

See also Chappell v. United States, 160 U. S. 499-509, 40 L. ed. 510-513, 16 Sup. Ct. Rep. 397; Horner v. United States, 143 U. S. 570-577, 36 L. ed. 266-269, 12 Sup. Ct. Rep. 522.

If, therefore, the whole case can come to this court by direct appeal under the allegations of this bill, and if all the questions, Federal or otherwise, may come up on such appeal, it must follow that either party aggrieved by the decision may appeal, and in this case, the complainant appealing, a cross appeal may be sued out by the defendant as to the matters decided in the same case against him. If he fails to take such appeal the correctness of the decision as against him will be presumed. New Orleans & B. S. Mail Co. v. Flanders, 12 Wall. 130, 20 L. ed. 249; Chittenden v. Brewster, 2 Wall. 191-196, 17 L. ed. 839-841.

The motion to dismiss the cross appeal must be denied.

Coming to the merits of the case, the grounds of Federal relief will first be considered. It is claimed that certain sections of the act of the general assembly of Missouri, which make the tax bills levied to pay the contract price for the paving, a lien upon the complainant's real estate, deprive him of his property without due process of law, and deny to him the equal protection of the laws. This argument is predicated on § 5989 of the Revised Statutes of Missouri.

The exact point of objection is that the improvement is not to be made if a majority of the resident owners of the property liable to taxation therefor shall file with the city clerk a protest against such improvement, which privilege of protest is not given to nonresident owners, thereby discriminating against them. It is well settled, however, that not every discrimination of this character violates constitutional rights. It is not the purpose of the 14th Amendment, as has been frequently held, to prevent the states from classifying the subjects of legislation, and making different regulations as to the property of different individuals differently situated. The provision of the Federal Constitution is satisfied if all persons similarly situated are treated alike in privileges conferred or liabilities imposed. Kentucky Railroad Tax Cases, 115 U. S. 321, 29 L. ed. 414, 6 Sup. Ct. Rep. 57; Hayes v. Missouri, 120 U. S. 68, 30 L. ed. 578, 7 Sup. Ct. Rep. 350; Magoun v. Illinois Trust & Sav. Bank, 170 U. S. 283, 42 L. ed. 1037, 18 Sup. Ct. Rep. 594; Gulf, C. & S. F. R. Co. v. Ellis, 165 U. S. 150, 41 L. ed. 666, 17 Sup. Ct. Rep. 255. The alleged discrimination is certainly not an arbitrary one; the presence within the city of the resident property owners, their direct interest in the subject-matter, and their ability to protest promptly if the means employed are objectionable, place them on a distinct footing from the nonresidents, whom it may be difficult to reach. Furthermore, there is no discrimination among property owners in taxing for the improvement. When the assessment is made it operates upon all alike. It has been held to be within the power of the legislature of Missouri to authorize the council to order the improvement to be made without consulting property owners. Buchan v. Broadwell, 88 Mo. 31. If the legislature saw fit to give to those most directly interested, and whose consent could be most readily obtained, the right to protest, such action did not deprive other persons of rights guaranteed by the Constitution.

Further objection on Federal grounds is urged, in that the specification of Trinidad Lake asphalt for this improvement is in violation of the interstate commerce clause of the Constitution of the United States, and of the so-called Sherman act of July, 1890. The right to provide for this paving was vested by the Missouri statute in the board of aldermen. The right to select the material for the paving was vested in that body; they saw fit to choose Trinidad Lake asphalt for the paving. Their right so to do, under the charter powers of such cities as Westport, notwithstanding competitive bidding is thereby rendered impossible, has been sustained by the supreme court of Missouri. Barber Asphalt Pav. Co. v. Hunt, 100 Mo. 22, 8 L. R. A. 110, 18 Am. St. Rep. 530, 13 S. W. 98; Warren v. Barber Asphalt Pav. Co. 115 Mo. 572, 22 S. W. 490; Verdin v. St. Louis, 131 Mo. 26, 33 S. W. 480, 36 S. W. 52. With the wisdom of this choice the courts have nothing to do; and in this case we are only concerned to inquire as to the alleged violation of Federal rights in such selection. The argument is that Trinidad Lake asphalt, being a product of a foreign country, and brought into Missouri, and there being other deposits in other states within the United States from which suitable asphalt could be had, the specification of this kind of asphalt is an interference with, and a regulation of, interstate commerce, in violation of the exclusive right of Congress conferred by the Constitution. It is unnecessary to cite largely from cases in this court which hold that only such acts as directly interfere with the freedom of interstate commerce are prohibited to the states. Kidd v. Pearson, 128 U. S. 1, 32 L. ed. 346, 2 Inters. Com. Rep. 232, 9 Sup. Ct. Rep. 6, in which case, Mr. Justice Lamar, speaking for the court, said (p. 23, L. ed. 351, Inters. Com. Rep. p. 237, Sup. Ct. Rep. p. 11): 'As has been often said 'legislation [by a state] may, in a great variety of ways, affect commerce and persons engaged in it, without constituting a regulation of it within the meaning of the Constitution." Pennsylvania R. Co. v. Hughes, 191 U. S. 477, ante, p. 132, 24 Sup. Ct. Rep. 132, and cases cited in the opinion. The right of a state, in the exercise of the police power, to make regulations which indirectly affect interstate commerce, has been frequently sustained. In the present case it may be that the use of this kind of asphalt, under municipal authority conferred by the state will, in a limited degree, affect interstate commerce; but it certainly is not one of those direct interferences with the power over, and express control of, the subject given by the Constitution to Congress. In this day of multiplied means of intercourse between the states there is scarcely any contract which cannot, in a limited or remote degree, be said to affect interstate commerce. But it is only direct interferences with the freedom of such commerce that bring the case within the exclusive domain of Federal legislation.

The attempt to invoke the provisions of the Sherman act in this case is equally unavailing. That act has been recently considered in the Northern Securities Cases,1 decided at this term, and its construction and the nature of the remedies under it determined. It is not intended to affect contracts which have a remote and indirect bearing upon commerce between the states. Hopkins v. United States, 171 U. S. 578, 43 L. ed. 290, 19 Sup. Ct. Rep. 40; Addyston Pipe & Steel Co. v. United States, 175 U. S. 211, 44 L. ed. 136, 20 Sup. Ct. Rep. 96.

In addition to the ground by which Federal jurisdiction was established in the courts below, it is alleged that the tax bills should be held void because they were obtained by undue influence of the agents of the paving company, improperly exercised to obtain the needed muncipal action. The court below held, and an examination of the testimony has brought us to the same conclusion, that there was nothing in the case to establish the charges of fraud and corruption, although the record does show that an agent of the defendant company was active and perhaps influential in obtaining signatures to the petition which specified Trinidad Lake asphalt for this improvement; yet, in the absence of proof of fraud or corruption, we do not think the contract and resulting levies can be set aside for this reason. It is one thing to disapprove of such measures as a matter of propriety of action, but quite another to set aside a contract, especially after the full performance of its terms.

Upon the cross appeal, the learned judge in the court below held that the Wyandotte street tax bills were void, because that street had been previously paved with macadam in the years 1892-1893, four or five years before the asphalt paving was laid, which macadam he found to be in good condition, and but little worn. The effect of this decree was, while finding against complainants as to the allegations of fraud and collusion in obtaining the contract, to hold that, in the opinion of the trial judge, the repaving of Wyandotte street was unnecessary. We think this conclusion overlooks the fact that the power to construct, improve, and pave streets was vested by the law of Missouri, as it generally is, in the board of aldermen. Mo. Laws 1895, 65, § 85 to § 95, inclusive. The necessity of such improvements is a matter of which they are the exclusive judges, and their judgment is not to be interfered with by the courts, except in cases of fraud or gross abuse of power. This power of the city board is a continuing one, and the mere fact that a pavement has been once laid does not require the interference of the courts when the governing body of the city, in the exercise of its judgment, has determined that the necessity for repaving has arisen. The law has vested this power in the representatives of the city, and the courts are not at liberty to determine whether the judgment is exercised wisely or unwisely. If this were not so, a contractor, who acts under the direction, and because of the action, of the city authorities in determining the necessity of an improvement, must lose his compensation if, upon the suit of a property owner, the courts shall take a different view of the necessity of the improvement. In other words, the contractor, though acting in good faith and complying in all respects with his agreement, lawfully made, must abide the judgment of the courts as upon appeal from the tribunal solely empowered by law to pass upon the necessity of the improvement, and to make the necessary contracts to carry it out.

As we have said, there may be cases of fraud or arbitrary abuse of power, when the courts will intervene. Under other circumstances the municipality and property owners interested are bound by the acts of their agents. The authorities amply sustain this view. 2 Dill. Mun. Corp. 4th ed. § 686; Wabash R. Co. v. Defiance, 167 U. S. 88, 42 L. ed. 87, 17 Sup. Ct. Rep. 748; Skinker v. Heman, 148 Mo. 349, 49 S. W. 1026: Warren v. Barber Asphalt Pav. Co. 115 Mo. 580, 22 S. W. 490.

Applying the principles settled by the authorities to the facts disclosed in this case, we do not find such evidence of fraud or gross abuse of power as would warrant the setting aside of the tax bills for this improvement. The testimony tends to show that the macadam was considerably worn; it replacement, to the extent of laying an asphalt pavement on top of it, was deemed necessary by the city authorities. It does not appear that any protest or objection was made during the progress of the work. A majority of the resident owners of lots abutting upon the part of the street to be improved had petitioned for the asphalt pavement. There is considerable testimony tending to show that the value of abutting property was enhanced by the improvement. These and kindred matters were before the board. It is not our province to review their judgment, and we do not think the courts are authorized to interfere with the discretion vested in them in making the improvement under the circumstances shown. To hold otherwise would be, as we have said, to substitute the judgment of the court as to the expediency or necessity of making such improvement for that of the body delegated by law with the power and responsibility of action in the premises.

The court below, having properly held that the case alleged must fail on the other grounds, should have regarded the judgment of the board of aldermen as to the necessity of repaving Wyandotte street as conclusive upon it. The conclusion reached renders it unnecessary to consider whether the complainant, having failed to protest or object to the work before it was begun or during its progress, can be heard in a court of equity to object to the tax bills assessed for the benefit of the contractor, after the work is completed in compliance with the contract.

We think the court below erred in adjudging the tax bills on Wyandotte street to be void, and so much of the decree is reversed with costs; the decree as to the other streets is affirmed, and the case remanded to the court below, with instructions to dismiss the bill.
