delivered the opinion of the court:
This is a writ of error to review a judgment of the circuit court of Warren county entered in July, 1916, for $582.85, in favor of defendant in error and against plaintiff in error. The case has been brought directly to this court on the ground that the statute under which the summons in the cause was served is unconstitutional.
The return of the sheriff of Warren county is as follows : “I have duly served this writ on the within named James E. Bennett, trading as James E. Bennett & Co., by reading the same and at the same time delivering a true copy thereof to William J. Loesch, agent of said James E. Bennett, trading as James E. Bennett & Co., at his place of business in said county of Warren, the within named James E. Bennett, trading as James E. Bennett & Co., being a nonresident and not found in my county, as I am herein commanded, this 29th day of January, A. D. 1916.” No personal service was ever had upon the plaintiff in error. His counsel entered for him a special appearance, especially limited and qualified to question the jurisdiction of the circuit court, and moved the court, in writing, to quash said service and summons on the ground that section 13 of the Practice act, under which said service was made, was unconstitutional.
Said section 13, so far as it applies to this question, reads as follows: “Any non-resident person * * * having a place or places of business in any county of this State in which suit may be instituted, may be sued by the usual *539and ordinary name which such person * * * has assumed and under which such person * * * is doing business and service of process may be had in such county upon such person * * * by serving the same upon any agent of such person * * * within this State.” (Hurd’s Stat. 1916, p. 1990.)
Counsel for plaintiff in error argue that this provision of section 13 applies to all non-residents of the county upon whom service is had, whether they reside in other counties of this State or outside the State, and that as the judgment in this case is in personam and not in rem, the statute must be held invalid as in violation of the due process clauses of the constitution of this State and of the fourteenth amendment to the Federal constitution, under the reasoning of the authorities in this and other jurisdictions. Flexner v. Farson, 268 Ill. 435, and cases cited.
Counsel for defendant in error concede that if said section 13 must be construed as contended for by opposing counsel it is unconstitutional so far as it applies to persons residing outside of this State, but they insist that the word “non-resident,” as used in that section of the Practice act, can be construed as applying only to persons who are nonresidents of the county where the service is had but are residents of this State. In Watson v. Coon, 247 Ill. 414, this court, in construing said section 13 of the Practice act, held that the word “non-resident,” as used in the section, included people who resided in other counties within the State, and sustained the service and summons in that case. It is true, however, as argued by counsel for plaintiff in error, that the constitutionality of the statute was not there being considered.
Every presumption must be made and every reasonable doubt resolved in favor of the validity of a statute. If a statute is capable of two constructions, one of which will render it invalid and the other valid, the court should adopt the construction which will uphold the validity of the act. *540 (Hogan v. Akin, 181 Ill. 448.) Courts will not construe a statute so as to make it unconstitutional if any other reasonable construction can be placed upon it which will.malee it effectual. A law may be enacted in such general terms that it will apply to all conditions of fact and not be prohibited by the constitution, and yet if applied to particular conditions of fact it would destroy constitutional rights and the application of the law to such particular conditions of fact would be unconstitutional, but in such .case the law is invalid only as applied to the particular conditions and valid as applied to other conditions. (People v. Rodenberg, 254 Ill. 386.) It is the general rule, also, that only the invalid parts of a statute are without legal effect, provided the invalid parts are not so blended with and a part of the rest of the act that the legislature would not have passed the remainder of the act without the unconstitutional portion. (Sheldon v. Hoyne, 261 Ill. 222.) This general rule is not limited to instances where distinct parts of an act are invalid. It applies as well to exclude from the operation of the statute, without rendering such statute invalid, subjects and classes lying without the legislative intent although comprehended within the general terms of the act. (People v. Butler Street Foundry Co. 201 Ill. 236.) “A legislative act may be entirely valid as to some classes of cases and clearly void as to others. A general law for the punishment of offenses which should endeavor to reach, by its retroactive operation, acts before committed as well as to prescribe a rule of conduct for the citizen in the future would be void so far as it was retrospective, but such invalidity would not affect the operation of the law in regard to the cases which were within the legislative control. A law might be void as violating the obligation of existing contracts but valid as to all contracts which should be entered into subsequent to its passage, and which therefore would have no legal force except such as the law itself *541would allow. In any such case the unconstitutional law must operate as far as it can, and it will not be held invalid on the objection of a party whose interests are not affected by it in a manner which the constitution forbids. If there are any exceptions to this rule they must be of cases, only, where it is evident, from a contemplation of the statute and of the purpose to be accomplished by it, that it would not have been passed at all except as an entirety and that the general purpose of the legislature will be defeated if it shall be held valid as to some cases and void as to others.” Cooley’s Const. Lim. (7th ed.) 250; City of Chicago v. Wolf, 221 Ill. 130.
While this section of the Practice act is so worded that its construction on the question here involved is not entirely free from doubt, we think, under the reasoning in Watson v. Coon, supra, it can be reasonably construed so that the word “non-resident,” as used therein, shall apply only to non-residents of the county who are residents of the State. Manifestly, the legislature might well have enacted this section with that meaning. It is conceded by counsel for the plaintiff in error that an act so limited would be constitutional. This court has held that matters upon which the legislature has no power to pass will be excluded from the statute although included within the general terms of the act. (People v. Butler Street Foundry Co. supra.) “A law which is unconstitutional within certain limitations, if in terms it exceeds or fails to notice those limitations, may yet be entirely operative within its legitimate sphere and properly held to have the application which thus confines it. Indeed, where two governments, like those of the United States and the commonwealth, exercise their authority within the same territory and over the same citizens, the legislation of that which as to certain subjects is subordinate should be construed with reference to the powers and authority of the superior government and not be deemed as *542invading them unless such construction is absolutely demanded.” Commonwealth v. Gagne, 153 Mass. 205.
Under the reasoning of these and similar authorities in this and other jurisdictions this act must be held constitutional, as intending to apply only to residents of the State who are non-residents of the county where, service is had. The reasoning in Flexner v. Farson, supra, in passing on the Kentucky statute, is not in any way controlling as to this statute, as the Kentucky statute there in question used language which clearly and plainly applied only to people residing in other States and not in Kentucky.
Counsel for plaintiff in error further insist that even though the statute be held constitutional and as meaning just as we have construed it, still this case should be reversed because the return of the sheriff does not show that plaintiff in error was a resident of the State; that a sheriff’s return cannot be pieced out by intendments and references but that the jurisdiction of the court must be shown by the return itself: The authorities cited by counsel on this question are none of them on all-fours with this case. Neither do we consider the reasoning in any of them as controlling here. The return in Watson v. Coon, supra, was worded substantially as was the return in this case, and that return was held good.
This statute being construed as applying only to residents of the State and not as applying to those living outside of the State, the conclusion necessarily follows that under it the sheriff can only serve the summons legally in cases where a principal residing in this State is reached by substituted service on persons in the county. If persons who are non-residents of the State are sought to be served under this section and that fact is not shown by the return of the sheriff, it can be shown in a proper way and the service quashed.
The judgment of the circuit court will be affirmed.
Judgment affirmed.
