Suit was brought in the circuit court of the city of St. Louis by the Construction Company to recover upon a special tax-bill issued by the city of St. Louis for the construction of the sewer in what is known as Manchester Road sewer district No. 111, city of St. Louis. The Construction Company recovered a judgment on the tax-bills against the plaintiffs in error, who were owners of abutting property. Upon appeal to the Supreme Court of Missouri the judgment below was affirmed upon hearing and rehearing. Prendergast Const. Co. v. Goldsmith, 273 Mo. 184, 201 S. W. 354.

The record discloses that the sewer, for the construction of which the assessment was made, was constructed in a certain boulevard known as Kingshighway Boulevard. On the east of this boulevard, and fronting on the same for a considerable distance, is a tract belonging to the city, and known as Tower Grove Park; this property was not assessed for the building of the sewer. This omission is alleged to be of such an arbitrary and discriminatory character as to render the ordinance making the assessment void as a deprivation of federal constitutional rights secured to the plaintiffs in error by the due process and equal protection clauses of the Fourteenth Amendment.

The circuit court made findings of fact in which it found that there was no evidence tht the municipal assembly of the city of St. Louis, in passing the ordinances in question, was actuated by motives of fraud or oppression; that such motives, if any, must be inferred solely from the failure to incorporate parcels or tracts of land in the sewer district, the topography of which might render it necessary or expedient to then, or thereafter, drain the water or sewage therefrom into the sewer. The court recites the nature of the title of the tract known as Tower Grove Park.

It appears that the park had been conveyed to the city, the grantor reserving therefrom a strip 200 feet wide, surrounding the same. The court found that the western front of the tract, thus conveyed to the city included the western gate or entrance of the park and the strip of 200 feet in width, surrounding the park proper, and embraced a total frontage along Kingshighway of about 1470 feet, and that none of the property included within Tower Grove park and the strip of 200 feet in width, reserved for a residence property, was included within the taxing district for such sewer construction. The court also finds that with the exception of an area composing some 300 feet, each way, located at the southwestern corner of the Park, the western part of the park for a distance of some 600 feet east of Kingshighway is of an elevation higher than Kingshighway between Arsenal street and Magnolia avenue, and the natural drainage thereof is in the main westwardly towards Kingshighway and that before the building of the sewer in question surface water and hydrants drained from said part of the park through drains and gutters under said street and sidewalk to a point west of Kingshighway. That whatever drains for surface and hydrant water existed in said western and north western portion of the park led into that section of the sewer in question, situated in Kingshighway adjoining the park; but the court finds that it is unable to determine from the evidence as to when such connection with said sewer was accomplished, or by whom. The court also finds that at the time the work in question was performed it was provided by the revised ordinances of the city of St. Louis that water draining from roofs of houses should not flow over sidewalks, but should be conducted through pipes to a sewer if available, and if not then through pipes below the sidewalk, and into the open gutter of the street. The court does not find from the evidence that it was not possible or feasible to drain the surface water falling upon or collected from that portion of Tower Grove Park, and the reserved strip of 200 feet, which is higher than and inclined towards Kingshighway, from the surface of said land in any other manner than through or by the district sewer constructed in Kingshighway, and that sewage from houses upon said reserved strip, if any there ever be, cannot be disposed of by means other than said sewer.

As conclusions of law the court finds that it was within the powers of the municipal assembly, in the passage of the ordinances establishing the sewer district wherein the work sued for was performed, to embrace and designate therein only such real estate as, in their judgment, should be benefited thereby; that the discretion vested in the municipal legislature was not subject to review by this court, unless the powers of the legislature were affirmatively shown to have been exercised fraudulently, oppressively or arbitrarily. And the court found that the mere omission of the lands from said district which might, at one time, be reasonably included in the sewer district in question, or as to which it is reasonable to assume that the same would be more conveniently served by the sewer in question than any other, did not justify the court in concluding that the municipal assembly, in omitting said lands from the sewer district in question, was actuated by motives of fraud, or oppression; or that the prima facie liability of defendants established by the certified special tax-bill is thereby rebute d and overturned.

On the facts and conclusions of law the judgment was affirmed by the Supreme Court of Missouri.

The establishment of sewer districts was committed to local authorities by the charter of the city of St. Louis which had the force and effect of a statute of the State. That charter provided that within the limits of the district prescribed by ordinance recommended by the board of public improvements, the municipal assembly might establish sewer districts, and such sewers may be connected with a sewer of any class or with a natural course of drainage. See section 21, Woerner's Revised Code of St. Louis 1907, p. 410.

The mere fact that the court found that a part of Tower Grove Park might have been drained into the sewer, it was held by the Missouri courts, under all the circumstances, did not justify judicial interference with the exercise of the discretion vested in the municipal authorities. The court commented on the fact that it was not shown that any considerable amount of surface water was conducted away from the park by this sewer. Much less do such findings afford reason for this court in the exercise of its revisory power under the federal Constitution to reverse the action of the state courts, which fully considered the facts, and refused to invalidate the assessment.

As we have frequently declared, this court only interferes with such assessments on the ground of violation of constitutional rights secured by the Fourteenth Amendment, when the action of the state authorities is found to be arbitrary, or wholly unequal in operation and effect. We need but refer to some of the cases in which this principle has been declared. Embree v. Kansas City Road District, 240 U. S. 242, 36 Sup. Ct. 317, 60 L. Ed. 624; Withnell v. Ruecking Construction Co., 249 U. S. 63, 39 Sup. Ct. 200, 63 L. Ed. 479; Hancock v. Muskogee, 250 U. S. 454, 39 Sup. Ct. 528, 63 L. Ed. 1081; Branson v. Bush, 251 U. S. 182, 40 Sup. Ct. 113, 64 L. Ed. ——, decided December 22, 1919.

We find no merit in the contention that a federal constitutional right was violated because of the refusal to transfer the cause from the division of the Supreme Court of Missouri, which heard it, to the court en banc. See Moore v. Missouri, 159 U. S. 673, 679, 16 Sup. Ct. 179, 40 L. Ed. 301.

Affirmed.
