delivered the opinion of the court.
On April 14, 1938, plaintiffs, who are 115 patrolmen in the classified service of the department of police of the city of Chicago, filed their complaint in the superior court of Cook county praying that they be granted a writ of mandamus commanding defendants to appoint each of them to the rank of sergeant in the police department of the city. On May 9,1938, defendants filed a motiоn to strike the writ of mandamus and to dismiss the suit. The motion set up as a ground for defense that the action was barred under the doctrine оf res judicata by virtue of the proceedings culminating in the opinion filed in the case of People ex rel. Richards v. Allman,
There is no substantial disagreement as to the facts, which are set forth in the case of People ex rel. Richards v. Allmam, supra,
Plaintiffs argue that the motion on which thе court acted was unsupported by an affidavit as contemplated by section 48 of the Civil Practice Act (sec. 172, ch. 110, Ill. Rev. Stat. 1937). Our quotation from the affidavit of Mr. Lundquist shows that there was an affidavit. The facts were based entirely on records available to аll the parties and in our opinion the affidavit was sufficient. Furthermore, the record shows that plaintiffs filed a counter-affidavit and did nоt object nor make any point that defendants’ motion was not supported by a proper affidavit. Therefore, even though a proper affidavit were not attached, such failure of plaintiffs to object amounted to a waiver of the point.
Plaintiffs maintain that the burden of proving the defense of res judicata is on the parties raising it. That statement is correct. As pointed out, the proof consists entirely of matters of record and the dispute arises as to the conclusions to be arrived at from the record. We have already pointed out that the records establish the defense of res judicata.
Plaintiffs assert that where a cause of action is imperfectly or insufficiently pleaded the judgment therein does not bar a subsequent cause оf action well pleaded. In the Richards case the cause of action was not defectively pleaded. That opinion involved the construction to be placed on various sections of the Civil Service Act (ch. 24½, Ill. Rev. Stat. 1937 [Jones Ill. Stats. Ann. 23.001 et seq.]).
Our perusal of the records, abstracts and briefs filed in the 2 cases and the opinion in the Richards case convinces us that the instаnt action is barred by the previous judgment.
We have considered other points that have been urged by counsel, but in view of what has been said it is unnecessary to further extend this opinion.
For the reasons stated, the judgment of the superior court of Cook county is affirmed.
Judgment affirmed.
