Plaintiff, Michael A. Marino, appeals the trial court’s summary judgment dismissing his complaint for damages against defendants, E. L. Willoughby and the City of Pueblo. We reverse.
The record discloses the following undisputed facts. On April 14, 1974, Marino, then a Pueblo police officer, attempted to commit suicide. In June of 1974, Willough-by, then Pueblo’s Chief of Police, terminated Marino’s employment, primarily because of the April incident.
Marino appealed his discharge to the Pueblo Civil Service Commission. Marino appeared and was represented by counsel at an evidentiary hearing conducted by the Commission. He did not challenge his discharge on federal grounds. The Commission upheld the termination in August of 1974. Marino did not exercise his right to seek review of that decision in the district court.
On October 23, 1978, Marino filed the complaint in this case alleging two claims for relief. The first claim seeks damages on the ground that his 1974 discharge violated his civil rights as protected by federal law. Although the first claim also refers to certain Colorado statutory provisions, Mari-no has indicated on appeal that his first claim is “an action for enforcement of his civil rights, specifically his right to a pre-termination hearing prior to discharge from his employment, pursuant to 42 U.S.C.A. § 1983.” The second claim seeks damages for alleged violations of Marino’s rights as a handicapped person pursuant to 29 U.S.C.A. §§ 701, 706, 791 and 794, protecting handicapped individuals. Neither of these claims for damages nor the grounds upon which they are based were raised before the Commission in 1974.
The sole issue on appeal is whether Marino’s complaint is barred by the doctrine *730of res judicata.1 That doctrine is based upon the salutary principle that matters once litigated must be deemed conclusively resolved by that litigation. When applicable, the doctrine not only bars re-litigation of all issues previously decided, but also bars litigation of all issues that could have been decided in the previous litigation. Pomeroy v. Waitkus, 183 Colo. 344, 517 P.2d 396 (1973).
Marino contends that the Commission could not have determined his federal claims in 1974. We agree.
As applicable in 1974, the City Charter of Pueblo § 8-4 contained the following pertinent provisions:
“It shall be the duty of the Civil Service Commission in compliance with rules established by the council:
a. To hear appeals from any action . . . dismissing any employee in the Classified Service as hereinafter provided, and to report in writing to the superior taking the action appealed from, its findings and decisions. Any superior taking action such as above mentioned shall present such an employee, in writing, a statement as to what action is being taken and for what reason. If the employee desires, he may take the complaint to the Chairman of the Civil Service Commission and be given a hearing by the Commission within five (5) days .... The decisions of the Civil Service Commission on appeals shall be final unless reversed by the District Court;
b. To provide for reinstatement of any employee found innocent of preferred charges ....”
In addition, the City Charter of Pueblo § 6-12-l(b) required the Commission to grant hearings to employees who appeal any disciplinary action involving dismissal.
These provisions do not authorize the Commission to grant monetary relief for violations of federal rights established by 42 U.S.C.A. § 1983 and 29 U.S.C.A. §§ 701, 706, 791 and 794. Marino requests such monetary relief here, thus raising justiciable issues of liability and damages. Although in 1974 Marino might have chosen to challenge his dismissal by raising similar issues as defenses to that dismissal, the Commission had no jurisdiction at that time to resolve completely the federal statutory and constitutional claims Marino raises here.
Willoughby and Pueblo contend that the decision in Umberfieid v. School District No. 11, 185 Colo. 165, 522 P.2d 730 (1974) controls this case. Umberfieid held that the doctrine of res judicata constituted a bar to a petition filed with the Colorado Civil Rights Commission by a teacher who previously had been discharged pursuant to Colorado’s Teacher Tenure Act, had appealed his termination, and had not sought judicial review of an administrative decision rejecting his appeal. The petition alleged a violation of § 80-21-6(2), C.R.S.1963 (1969 Perm.Supp.), of the Colorado Anti-discrimination Statute.
Because Umberfieid did assert some claims of discrimination during the prior administrative proceedings, a majority of the court concluded that all his employment discrimination claims were barred by the doctrine of res judicata. The court concluded that the teacher tenure panel there involved had jurisdiction to consider all of Umberfield’s discrimination claims. Furthermore, the Civil Rights Commission had no authority to award damages. Thus, had Umberfieid raised his discrimination claims as defenses to his dismissal, and prevailed, he would have resolved completely all claims against the employer that could have been resolved by the Civil Rights Commission.
Here Marino did not raise either of his federal claims during the administrative proceedings, and the Commission did not have jurisdiction to resolve such claims. Moreover, even if Marino had presented to the Commission the grounds underlying the federal claims here asserted as defenses to his dismissal, a decision by the Commission to reinstate Marino could not have resolved *731completely his claims for damages against Willoughby and Pueblo based on alleged violations of federal rights.
In the circumstances of this case, we conclude that the doctrine of res judicata does not bar Marino’s federal claims. Therefore, we do not consider Marino’s argument that, pursuant to Lombard v. Board of Education, 502 F.2d 631 (2d Cir. 1974), the state doctrine of res judicata is inapplicable to the particular federal claims asserted.
Judgment reversed and cause remanded for further proceedings.
RULAND, J., concurs. VAN CISE, J., dissents.. The parties have so stipulated. The applicability, if any, of the notice provisions of § 24-10 109, C.R.S.1973, which may involve factual disputes, remains to be determined.
