The following opinion was filed June 21, 1926:
Steyens, J.The legislature of 1925 passed ch. 431 creating sec. 40.85 of the Statutes, which provides among other things:
“Whenever a common school district maintaining a high school consists of territory both within and without the corporate limits of any city or village having a population of five hundred or more, the territory lying outside such limits which is used for agricultural purposes may be detached as hereinafter provided; but this section shall not apply to any district which includes within its limits more than one city or village, or a city and a village, or which maintains common or graded schools outside of the city or village limits.”
Sec. 3, art. X, of the constitution of Wisconsin provides:
“The legislature shall provide by law for the establishment of district schools, which shall be as nearly uniform as practicable.”
Sec. 40.85 clearly discloses the legislative intent to classify common school districts maintaining high schools on the basis of the presence or absence of agricultural land within such school districts. The validity of the act here in question must be tested by the well established rules which determine when such a classification may be made.
Among the essentials of a constitutional classification are that—
“(1) All classification must be based upon substantial distinctions which make one class really different from an*287other. (2) The classification adopted must be germane to the purpose of the law. . . . (5) The characteristics of each class should be so far different from those of other classes as to reasonably suggest at least the propriety, having regard to the public good, of substantially different legislation. . . . ‘The true practical limitation of the legislative power to classify is that the classification shall be based upon some apparent natural reason, — some reason suggested by necessity, by such a difference in the situation and circumstances of the subjects placed in different classes as suggest the necessity or propriety of different legislation with respect to them.’ ” State ex rel. Risch v. Trustees, 121 Wis. 44, 54, 98 N. W. 954.
It is not necessary to determine whether the presence or absence of agricultural lands within the limits of a common school district maintaining a high school constitutes a valid basis for a classification of school districts. The classification made by this act has a much narrower basis. In order to come within the classification established by this act two facts must appear: first, that such district contains lands used for agricultural purposes, and second, that it does not contain more than one city or village.
Keeping in mind the legislative purpose to classify school districts on the basis of the presence or absence of agricultural lands in such district, the fact that a district contains one or more centers of urban population cannot be the basis of a classification which is germane to the purpose of the law. Such a classification cannot be said to be based on a substantial distinction which makes the class with two centers of urban population really different from the class which has only one city or village. Clearly the characteristics of a class of school districts having two or more centers of urban population is not so far different from the class having only one city or village as to reasonably suggest the propriety, having regard to the public good, of substantially different legislation applicable to each class. The classification made by this act is purely arbi*288trary, — not one based on some apparent natural reason suggested by such a difference in the situation and circumstances of the districts placed in different classes as to suggest the necessity or propriety of different legislation with respect to them.
The act is therefore invalid as being in conflict with the provisions of the constitution requiring the legislature in the creation of school districts to make them as uniform as practicable. In reaching this conclusion the court has “kept in mind that the necessity and propriety for classification are primarily legislative questions, the judgment of the legislature not to be disturbed unless it shall clearly appear that the limits of its constitutional authority have been overstepped.” State ex rel. Risch v. Trustees, 121 Wis. 44, 54, 98 N. W. 954.
This court always approaches the consideration of the constitutionality of a statute with deference for the act of a co-ordinate branch of the state government and always seeks to find a construction of the statute which will bring it into harmony with the mandate of the people of the state as expressed in the fundamental law of Wisconsin, which limits alike the power of the legislature and of the the courts. But the terms of the act'here in question are so plain and unambiguous as to leave no room for any construction that will bring the act into harmony with the constitutional mandate.
The provision of the act that it “shall not apply to any district which includes within its limits more than one city or village, or a city and a village,” cannot be disregarded and the rest of the act held valid, because this provision is expressly made one of the essential bases of the classification and is so intimately associated with the rest of the act that it cannot be separated from it without violating the *289clear legislative intent. To disregard this provision of the act would result in making the law apply to school districts which the legislature clearly intended should be exempt from the provisions of the statute.
By the Court. — Judgment affirmed.
