delivered the opinion of the court:
In this case, a State employing unit sought to discharge a certified employee for cause. After a hearing the Civil Service Commission found the employee guilty of the misconduct charged but imposed only a sanction of suspension. The question presented is whether a court on administrative review from such an order may set aside the suspension and order that on remand the employee be ordered discharged. We hold that under the circumstances here, such an order may be entered and affirm the action of the circuit court in doing so.
On March 21, 1979, the Department of Mental Health of the State of Illinois (DMH) initiated proceedings for the discharge of its employee, defendant Wayne C. Du Erenne, who then demanded a hearing pursuant to section 11 of the Personnel Code (Ill. Rev. Stat. 1977, ch. 127, par. 63blll). The charge alleged that defendant had mistreated a patient. A hearing was held before a hearing officer. On August 16, 1979, the Commission entered an order approving the recommendation of the *1073hearing officer finding defendant to have punched and kicked a patient who was under restraint. However, the order also found the circumstances to be mitigating and imposed, as the only sanction, that defendant be suspended for a period of 90 days in addition to the 30-day suspension which had initially been imposed by DMH. On September 19, 1979, that department appealed to the circuit court of Sangamon County pursuant to the provisions of section 11a of the Personnel Code. (Ill. Rev. Stat. 1979, ch. 127, par. 63bllla). On December 20, 1979, that court reversed the decision of the Commission and remanded the cause to it with directions to enter an order finding defendant to have been properly discharged. Defendant then appealed to this court.
Defendant does not dispute that an employing department such as DMH can obtain administrative review of a decision of the Civil Service Commission (Department of Registration & Education v. Aman (1973), 53 Ill. 2d 522, 292 N.E.2d 897), but maintains that such review should be limited to determining whether the Commission’s factual determination as to the employee’s misconduct was contrary to the manifest weight of the evidence. He contends that reviewing courts should give complete deference to the Commission’s determination of whether the misconduct, if proved, warranted a discharge or lesser sanction of suspension. He relies principally upon Nolting v. Civil Service Com. (1955), 7 Ill. App. 2d 147, 129 N.E.2d 236, and the more recent case of Epstein v. Civil Service Com. (1977), 47 Ill. App. 3d 81, 361 N.E.2d 782. In Nolting the circuit court on administrative review set aside a discharge order of the city of Chicago civil service commission and ordered reinstatement of the discharged employee upon condition that he waive back salary. The appellate court reversed, noting that the circuit court had, in effect, ordered a suspension and that under applicable legislation (Ill. Rev. Stat. 1953, ch. 24/á, par. 42) the city commission had no power to suspend an employee. The appellate court stated that the circuit court, on administrative review, could only determine whether (1) the finding on the question of whether the employee committed the misconduct charged was contrary to the manifest weight of the evidence, and (2) the determination in regard to discharge was related to the requirements of the employee’s service and not arbitrary or capricious. The court stressed the importance of the expertise of the city commission in determining cause and the harmful effect upon the employing unit for the court to force upon the employer an employee deemed by the city commission to require discharge. In Epstein the appellate court made similar admonitions in reversing a circuit court order which had reversed a discharge order of the Civil Service Commission.
Section 11 of the Personnel Code prohibits discharge except for “cause.” The Code does not define “cause” but cases have construed it to *1074constitute “substantial shortcoming which renders the employee’s continuance in office in some way detrimental to the discipline and efficiency of the service and which the law and sound public policy recognize” as reason for terminating the employee. Kreiser v. Police Board (1976), 40 Ill. App. 3d 436, 441, 352 N.E.2d 389, 394, aff'd (1977), 69 Ill. 2d 27, 370 N.E.2d 511; Parkhill v. Illinois Civil Service Com. (1978), 58 Ill. App. 3d 291, 374 N.E.2d 254; Epstein.
No case has come to our attention where the circuit court has set aside a Civil Service Commission order on grounds that the Commission had erroneously refused to impose a discharge. However, the propriety of the determination of whether proven misconduct was sufficient to constitute cause for discharge has been reviewed in Fox v. Illinois Civil Service Com. (1978), 66 Ill. App. 3d 381, 383 N.E.2d 1201, Parkhill, and Res v. Civil Service Com. (1977), 49 Ill. App. 3d 852, 365 N.E.2d 209. In Fox a discharge order was set aside. The proved misconduct of profanity was deemed insufficient as a matter of law to constitute cause for discharge. Similarly in Kreiser v. Police Board (1977), 69 Ill. 2d 27, 370 N.E.2d 511, and Fornuto v. Police Board (1976), 38 Ill. App. 3d 950, 349 N.E.2d 521, courts have set aside determinations of another independent agency that misconduct of tenured employees required discharge. The Fox (66 Ill. App. 3d 381, 388, 383 N.E.2d 1201, 1206) and Kreiser (40 Ill. App. 3d 436, 441, 352 N.E.2d 389, 394) opinions indicated that a commission’s determination to discharge might be overturned if the charges proved were “so trivial as to be unreasonable or arbitrary.”
The argument of defendant’s brief is directed entirely to the question of whether the circuit court could set aside the Commission’s determination not to discharge him. No contention is made that the circuit court’s ruling was improper because of the nature of the misconduct shown here, and we need not consider that question. We recognize the substantial deference that must be given to the Commission’s ruling on the question of cause. However, our examination of the record indicates that conduct of defendant in unnecessarily punching and kicking an already restrained mental patient was very grave even in the face of substantial provocation.
Defendant points out that in Kreiser, the supreme court (69 Ill. 2d 27, 370 N.E.2d 511) held that in properly overturning the discharge order, the trial court erroneously failed to remand to the city commission so that it might exercise its discretion as to imposition of a lesser sanction than that set aside. Even if a similar rule would ordinarily be applicable in a reverse situation and require remand to the commission to exercise its discretion in imposing a sanction more severe than that set aside, the rule would not apply here. The 90-day suspension imposed by the Commission, coupled with the 30-day suspension imposed by DMH, constituted the most *1075severe sanction less than discharge permitted by section 11 of the Personnel Code. Thus the reversal of the Commission’s order left no area for exercise by it of any discretion.
The order of the circuit court of Sangamon County appealed is affirmed.
Affirmed.
