Clark v. Kansas City (176 U.S. 114)/Opinion of the Court
The statute excepts from its operation lands used for agricultural purposes if owned by individuals. It includes such lands if owned by corporations. It is hence contended by plaintiff in error that the statute discriminates between the owners of agricultural lands, and between them again and the owners of all other lands, and infringes thereby the provision of the Constitution of the United States which guarantees to all persons the equal protection of the laws.

Of the discrimination between owners of agricultural lands the supreme court of Kansas said the defendants in error (plaintiffs here) cannot be heard to complain. 'Their lands are not agricultural lands. At least they do not allege them to be such lands, but on the contrary allege that parts of them are used for railroad purposes, and that the remaining portions are vacant and unoccupied lands held and possessed for railroad purposes. Owning no agricultural land, the defendants in error are not affected by the discrimination which the statute makes between the different classes of owners of such kind of land, and they cannot, therefore, be heard to complain on that score. 'A court will not listen to an objection made to the constitutionality of an act by a party whose rights it does not affect and who has therefore no interest in defeating it.' Cooley, Const. Lim. 6th ed. 196.' Albany County Supers. v. Stanley, 105 U.S. 305, 26 L. ed. 1044.

We concur in this view, and it would be difficult to add anything to its expression. The discrimination occurs only in a particular use of the lands, and it would seem obvious that such use must be shown to make a cause of action,-a right infringed and to be redressed. If the lands of the plaintiff belonged to an individual they would be subject to the statute. Where, then, is the discrimination? In that, it is claimed, if the lands were used for agriculture, being owned by a corporation, they would be subject to the statute, but would not be if owned by an individual. But that is not a discrimination immediate and actual against plaintiff in error. It does not now, and there is nothing in the record to show that it ever will, exist. Not a law alone, but a law and its incidence, are necessary to a justiciable right or injury; and it therefore follows if plaintiff has a grievance under the statute which this court can redress it comes from the discrimination between agricultural lands and other lands,-a cause of action, not because the plaintiff is a corporation, but because it is an owner of such lands, and one which it would have even if it were an individual.

The answer to that charge depends upon the power of the state to classify objects of legislation; necessarily a broad power, and one which this court has so many times decided exists, and so many times has defined and illustrated the limits upon it of the provision of the Constitution of the United States invoked by plaintiff in error, that farther definition would seem impossible, and any new instance of its application not without exact or analogous example in some decided case.

The reasoning of the cases we need not repeat. It is enough to say that the rule of the Constitution leaves to the discretion and wisdom of the state a wide latitude as far as interference by this court is concerned. It is not a substitute for municipal law; it does not invest power in this court to correct the impolicy and injustice of state laws, and the equality it prescribes is not for persons merely as such, but according to their relations. 'In some circumstances it may not tax A more than B, but if A be of a different trade or profession than B, it may. And in matters not of taxation, if A be a different kind of corporation than B, it may subject A to a different rule of responsibility to servants than B (Missouri P. R. Co. v. Mackey, 127 U.S. 205, 32 L. ed. 107, 8 Sup. Ct. Rep. 1161), to a different measure of damages than B (Minneapolis & St. L. R. Co. v. Beckwith, 129 U.S. 26, 32 L. ed. 585, 9 Sup. Ct. Rep. 207), and it permits special legislation in all its varieties. Missouri P. R. Co. v. Mackey, 127 U.S. 205, 32, L. ed. 107, 8 Sup. Ct. Rep. 1161; Minneapolis & St. L. R. Co. v. Herrick, 127 U.S. 210, 32 L. ed. 109, 8 Sup. Ct. Rep. 1176; Duncan v. Missouri, 152 U.S. 377, 38 L. ed. 485, 14 Sup. Ct. Rep. 570.' Magoun v. Illinois Trust & Sav. Bank, 170 U.S. 283, 42 L. ed. 1037, 18 Sup. Ct. Rep. 594.

And these principles have been affirmed in later cases, and a classification based on the difference between fire insurance and other insurance has been sustained; also on a difference between railroad and other corporations and of persons. Orient Ins. Co. v. Daggs, 172 U.S. 557, 43 L. ed. 552, 19 Sup. Ct. Rep. 281; Tullis v. Lake Erie & W. R. Co., 175 U.S. 348, 20 Sup. Ct. Rep. 136, 44 L. ed. --.

In Atchison, T. & S. F. R. Co. v. Matthews, 174 U.S. 96, 43 L. ed. 909, 19 Sup. Ct. Rep. 609, the majority of the court decided that, in consequence of the great peril and possibility of fires being communicated by the locomotives of railroad corporations, it was in the power of the state of Kansas to impose on them, in a suit successful against them, an attorney's fee, and not impose it on an unsuccessful plaintiff. It was said by Mr. Justice Brewer, after a review of the cases that --

'It is the essence of a classification that upon the class are cast duties and burdens different from those resting upon the general public. Thus, when the legislature imposes on railroad corporations a double liability for stock killed by passing trains it says, in effect, that if suit be brought against a railroad company for stock killed by one of its trains it must enter into the courts under conditions different from those resting on ordinary suitors. If it is beaten in the suit it must pay, not only the damage which it has done, but twice that amount. If it succeeds it recovers nothing. On the other hand, if it should sue an individual for destruction of its live stock it could under no circumstances recover any more than the value of that stock. So that it may be said that in matter of liability, in case of litigation, it is not placed on an equality with other corporations and individuals; yet this court has unanimously said that this differentiation of liability, this inequality of right in the courts, is of no significance upon the question of constitutionality. Indeed, the very idea of classification is that of inequality, so that it goes without saying that the fact of inequality in no manner determines the matter of constitutionality.' 174 U.S. 106, 43 L. ed. 913, 19 Sup. Ct. Rep. 613.

In the case at bar the distinction is between tracts of agricultural lands in a certain relation to cities and lands used for other purposes in such relation.

We think the distinction is justified by the principle of the cases we have cited. That principle leaves to the state the adaptation of its laws to its conditions. The growth of cities is inevitable, adn in providing for their expansion it may be the judgment of an agricultural state that they should find a limit in the lands actually used for agriculture. Such use, it could be taken for granted, would only be temporary. Other uses, certainly those to which the plaintiff puts its lands, can receive all the benefits of the growth of a city, and not be moved to submit to the burdens. Besides, such uses or manufacturing uses adjacent to a city may, for its order and health, need control. Affecting it differently from what farming uses do may justify, if not require, their inclusion within the municipal jurisdiction.

We think, therefore, that within the latitude which local government must be allowed the distinction is not arbitrary, and infringes no provision of the Constitution of the United States.

Judgment affirmed.
