tax act,” alone, which authorizes such change. It professes to confer power to suspend one law and substitute another, and, again, to suspend that substituted and substitute that suspended—and there, alone, is the attempt made to confer such power.
We can not doubt that this feature in the “city tax act” was a controling consideration in inducing its enactment, and one without which it could not have been enacted, because the act itself furnishes complete evidence to this effect. Otherwise, the provisions of the “city tax act” should have been, and we must presume would have been, engrafted, by way of an amendment, upon the general incorporation law. The unconstitutionalitv of the section conferring the option, therefore, must, of itself, condemn and render nugatory the balance of the act; for the rule is, as stated by Justice Cooley, in his valuable work on Constitutional Limitations, pp. 178-9: “If a statute attempts to accomplish two or more objects, and is void as to one, it may still be in every respect complete and valid as to the other; but if its purpose is to accomplish a single object only, and some of its provisions are void, the whole must fall, unless sufficient remains to effect the object without the aid of the invalid portion; and if they are so mutually connected with and dependent on each other, as conditions, considerations or compensations for each other, as to warrant the belief that the legislature intended them as a whole, and if all could not be carried into effect the legislature would not pass the residue independently, then, if some parts are unconstitutional, all the provisions which are thus dependent, conditional or connected, must fall with them.”
Our conclusion being, that the “city tax act” is unconstitutional, because it is a “ local or special law,” it follows that the judgment below is right, and must be affirmed.
In Spring et al. v. Olney, 78 Ill. 101, we sustained this act, against the objections then urged, but the point discussed in the present opinion was not then urged upon our attention; and the pressure of business upon us was such that we did not go beyond the points presented in the briefs, to consider
