delivered the opinion of the court:
Two taxpayers brought suit in the circuit court of Cook County against the Retirement Board of the Chicago Policemen’s Annuity and Benefit Fund. The suit seeks to enjoin the Board and its members from giving pension credit to certain policemen pursuant to a 1959 amendment of the statute. Two members of the police force eligible for benefits under the amendment intervened in the cause. The court granted the relief requested by plaintiffs, holding the amendment unconstitutional, and the interveners appeal.
The amendment provides that in computing prior service, credit shall be given for all time spent in military service, whether before or after becoming a policeman, “if such policeman shall have been on the eligible register for the position of policeman that existed prior to December 7, 1941 * * (Ill. Rev. Stat. 1961, chap. 24, par. 10— 7 — 55.) The eligible list that existed prior to December 7, 1941, was that of the 1938 civil service examination for the position of patrolman. Other eligible lists have come into existence from civil service examinations taken after December 7, 1941, but no policemen from these later lists are entitled to claim credit, under this provision, for time spent in military service.
The plaintiffs challenged the validity of the amendment on the ground, inter alia, that it grants special privileges to those policemen who were on the 1938 eligible list, and that there is no reasonable basis for treating them differently from other policemen with military service who were appointed from a subsequent list. The master to whom the cause had been referred found the limitation invalid on that ground, but recommended that the balance of the provision be upheld. This the court refused to do.
In this court the plaintiffs, without citing any authority thereon, renew their argument that the amendment violates section 22 of article IV of the Illinois constitution and that it cannot be made constitutional by striking out certain words therefrom. To reverse the ¡decree the intervenors urge that the master’s position was correct, that only the provision limiting the beneficiaries to those from the 1938 list was void, that when it is stricken the remainder is - complete in itself and capable of being executed independently of the rejected portion, and that the clause in question should be applied as if it read “if such policeman shall have been on an eligible register for the position of policeman.”
We cannot accept the argument. A legislative classification of persons, to be valid, must rest on some difference which has a reasonable relation to the object of the legislation. (Larvenette v. Elliott,
The intervenors have suggested no distinction, in respect to the purpose of the amendment, between policemen who had been on the designated eligibility register and those who had been on some other eligibility register. Indeed, the intervenors do not attempt to defend the amendment from this constitutional objection, but seek merely to limit the invalidity of the offending restriction, thus making the increased service credits available to all.
The fact that a part of an act is unconstitutional does not require that the remainder shall be held void unless all parts are so connected together as to depend upon each other. (McDougall v. Lueder,
The plaintiffs have taken a cross appeal from the decree insofar as it assesses them with one half of the master’s fee. They argue, again without the citation of authority, that since they were successful in their attack upon the unconstitutional provisions and conferred a benefit thereby upon the public treasury it is the pension fund which should pay the costs and that the chancellor abused his discretion in charging any part to the plaintiffs.
The contention cannot be sustained on this record. Insofar as it is relevant the applicable statute (Ill. Rev. Stat. 1961, chap. 33, par. 18) provides that the costs in chancery cases are in the discretion of the court — a discretion to be exercised according to equitable rules and principles. (La Salle Nat. Bank v. McDonald,
The decree of the circuit court of Cook County was correct, and it is affirmed accordingly.
Decree affirmed.
