(Affirming 104 Wis.2d 737, 313 N.W.2d 278.)

DAY, J.

This is a review of an unpublished decision of the court of appeals reversing an order of the circuit court for La Crosse county, Honorable William L. Reinecke, Judge, which had vacated an arbitration award in favor of Robert M. Fortney and reinstated the decision of the West Salem School Board (hereinafter Board) to discharge Mr. Fortney. The court of appeals remanded the case to the trial court with directions to issue an order confirming the arbitration award. We affirm the court of appeals.

The issue in this case is whether arbitrators appointed pursuant to a grievance procedure contained in a collective bargaining agreement could hold a de novo factual hearing to determine whether just cause existed for a school board to terminate a teacher, where the discharge decision was based on the findings and recommendation of a factfinder appointed by the Board. The Board argues that the arbitrator could only undertake a certiorari review of the record established at the hearing initiated by the Board and had no power to hold a de novo hearing. We hold that the arbitrators' interpretation of the collective bargaining agreement as permitting a de novo hearing is reasonable and does not unlawfully infringe upon the powers of the school board. We therefore affirm the decision of the court of appeals which reinstated the arbitrators' award.

Robert M. Fortney was employed as a teacher for the School District of West Salem from September, 1971, through August 20, 1979. In 1979, the Board received complaints by some students and parents that Mr. Fortney was making inappropriate statements in class. The Board investigated those complaints and, on March 5, 1979, informed Mr. Fortney that it proposed to discharge him. The Board appointed Attorney John Langer to conduct a fact finding hearing to determine whether the allegations against Mr. Fortney were true and, if so, warranted discharge. Mr. Fortney agreed to participate in the hearing, but informed the Board that he was specifically retaining his rights under a collective bargaining agreement (hereafter "agreement") which was then in effect between the School District of West Salem and the West Salem Education Association (hereinafter the "Union").

Mr. Langer conducted fact finding hearings on May 30 and June 18, 1979, concerning eleven allegations of improper conduct by Mr. Fortney. On August 17, 1979, Mr. Langer issued findings of fact sustaining nine charges against Mr. Fortney and recommended that he be discharged. The school board adopted those findings and recommendations and discharged Mr. Fortney on August 20, 1979. That same day Mr. Fortney invoked his rights under the agreement and filed a grievance against the Board's action.

The parties agreed to waive the preliminary steps of the grievance procedure and selected arbitrators as provided in the agreement. This arbitration panel conducted hearings on October 22, 23 and 24, and November 27 and 28, 1979.

The arbitration panel interpreted the agreement as permitting a full factual hearing on the nine charges against Mr. Fortney that were found to have occurred by Mr. Langer and adopted by the Board as the basis for discharging Mr. Fortney. The arbitration panel further held that the Board was bound by the findings and recommendations upon which it based its discharge of Mr. Fortney and so limited proof to those matters. Forty-nine witnesses testified at the hearings conducted by the arbitration panel.

On April 2, 1980, the arbitration panel, by a vote of two to one, held that of the nine charges of misconduct against Mr. Fortney, three never occurred, three constituted proper teaching methods, and three, while reflecting poor judgment by Mr. Fortney, did not justify discharge. The arbitrators ruled that no just cause existed for Mr. Fortney's discharge and ordered him reinstated with back pay.

On May 9, 1980, the Board moved the circuit court for La Crosse county to vacate the award. On May 29, 1980, Mr. Fortney petitioned the circuit court for La Crosse county to confirm the award. A hearing was held before Honorable William L. Reinecke. On July 11, 1980, Judge Reinecke overturned the arbitration decision and vacated the award on the ground that the arbitrators had exceeded their authority in conducting a de novo rather than a certiorari hearing as to whether just cause existed for the discharge. The court then reviewed the record and concluded that the Board's decision to discharge Mr. Fortney was supported by credible evidence and was not arbitrary and capricious. The court affirmed the Board's decision to discharge Mr. Fortney.

Mr. Fortney appealed to the court of appeals which reversed, holding that the arbitrators had acted within the scope of their authority, and remanded the case to the trial court with directions to confirm the arbitration award. The Board petitioned this court for review of the court of appeals decision. The petition was granted.

At issue in this case is whether the arbitrators exceeded their authority by interpreting the collective bargaining agreement to permit a de novo hearing on whether just cause existed to discharge Mr. Fortney, where a fact finding hearing had already been held concerning the propriety of the discharge. The arbitrators' decision should be vacated if that decision does not follow from the language of the collective bargaining agreement, is inconsistent with or violative of a statutory provision, or is incompatible with the United States or Wisconsin Constitutions. We hold that the decision and award is consistent with the collective bargaining agreement and applicable statutory and constitutional provisions and therefore affirm the court of appeals decision.

An arbitration award is presumptively valid and the court exercises only a supervisory role in reviewing an arbitration award. Professional Police Ass'n. v. Dane County, 106 Wis.2d 303, 306-07, 316 N.W.2d 656 (1982). As this court stated in Oshkosh v. Union Local 796-A, 99 Wis.2d 95, 102-03, 299 N.W.2d 210 (1980):

"The law of Wisconsin favors agreements to resolve municipal labor disputes by final and binding arbitration. An arbitrator's award is presumptively valid, and it will be disturbed only where invalidity is shown by clear and convincing evidence. . . .

"The parties bargain for the judgment of the arbitrator — correct or incorrect — whether that judgment is one of fact or law."

Despite this policy of deference to arbitration decisions, a court may vacate the decision and award in cases of misconduct by arbitrators, where it evinces a perverse misconstruction of the collective bargaining agreement, or if it is illegal or violates strong public policy. Professional Police Ass'n. v. Dane County, 106 Wis.2d at 308.

The Board argued before the trial court that the award should be vacated due to the misconduct of two of the arbitrators. The trial court found that no such misconduct occurred, and the Board neither appealed that ruling nor argued before this court that the award should be overruled due to any arbitrator's misconduct.

Because the arbitrator's power derives from the collective bargaining agreement, the decision and award must draw its authority from that agreement. Milwaukee Police Asso. v. Milwaukee, 92 Wis.2d 145, 158, 285 N.W.2d 119 (1979). The applicable provisions of the collective bargaining agreement are as follows:

"ARTICLE ONE: NEGOTIATION AGREEMENT. . . . C. BOARD SECURITY. It is recognized that the board has and will continue to retain the rights and responsibilities to operate and manage the school system and its programs, facilities, properties and activities of its employees; authorized by the State Statutes including but not exclusive of the following: . . .

"21. The application of the above statutes, will not be used in any attempt to diminish employee rights under 111.70 (MERA).

"ARTICLE III [THREE]: GRIEVANCE PROCEDURE. . . . C. PROCEDURE. . . . 4. Level Four. If the decision of the Board is not satisfactory' to the teacher or Welfare Committee, the grievance may be submitted to arbitration before an impartial arbitrator selected by the parties. The arbitrator to be selected in the following manner: The employer and the employee shall each appoint a member of the panel and shall notify the other of the name of his appointee to the Board within five (5) days of receipt of the written appeal. These two representatives shall meet in an attempt to select an impartial arbitrator. Failing to do so, they shall, within fifteen (15) days of the appeal request The Wisconsin Employment Relations Commission to submit a list of five names for their consideration. The employer and the employee representative shall determine by lot the order of elimination and thereafter each shall, in that order, alternately strike a name from the list, the fifth and remaining name shall act as the arbitrator.

"The arbitrator so selected will confer with the representatives of the Board and the Association and `hold hearings' promptly and will issue his decision on a timely basis. The arbitrator's decision will be in writing and will set forth his findings of fact, reasoning and conclusions of the issues submitted. The arbitrators will be without power or authority to make any decision which requires the commission of an act prohibited by law or which is violative of the terms of this agreement. Both parties agree to be bound by the award of the arbitrator and agree that judgment thereon may be entered in any court of competent jurisdiction.

"Each party shall bear the expenses of its legal representatives in this hearing. The fees and expenses of the arbitrator shall be shared equally by the parties." (emphasis added).

"ARTICLE SEVEN. WORKING CONDITIONS. . . . D. TEACHER EVALUATION. . . . 3. No teacher shall be disciplined or reprimanded without just cause and approval of the administration."

Pursuant to sec. 118.22(2), Stats. 1977, school boards have the exclusive power to hire and fire teachers:

" 118.22. Renewal of teacher contracts. . . . (2) On or before March 15 of the school year during which a teacher holds a contract, the board by which the teacher is employed or an employe at the direction of the board shall give the teacher written notice of renewal or refusal to renew his contract for the ensuing school year. . . . No teacher may be employed or dismissed except by a majority vote of the full membership of the board."

One of the purposes of the statute is to make it clear that hiring and firing of teachers cannot be done by school principals or superintendents but must be done by the school board.

This power is not, however, wholly unrestricted. The decision to discharge must be made in a way which protects the teacher's constitutional right to due process. Hortonville Ed. Asso. v. Joint School Dist. No. 1, 87 Wis.2d 347, 274 N.W.2d 697 (1979); Hortonville Ed. Asso. v. Joint Sch. Dist. No. 1, 66 Wis.2d 469, 489-91, 225 N.W.2d 658 (1975), rev'd on other grounds, 426 U.S. 482 (1976). Second, the power to discharge teachers, like other statutory duties of the Board pertaining to employment relations, may be limited by the provisions of a collective bargaining agreement entered into by the Board and a union representing teachers pursuant to the Municipal Employment Relations Act (MERA) secs. 111.70 -111.77, Stats. 1977. Richards v. Board of Education, 58 Wis.2d 444, 460a-460b, 206 N.W.2d 597 (1973).

The trial court correctly held that the fact finding procedure conducted by Mr. Langer sufficiently protected Mr. Fortney' s constitutional due process rights. However, Mr. Fortney had additional rights under the collective bargaining agreement.

While school boards are vested by statute with the primary responsibility for school district management, see chs. 118 and 120, Stats. 1977, they also have the power, pursuant to sec. 111.70, Stats., to limit their statutory powers by means of a collective bargaining agreement entered into with a Union composed of their employees.

The Board entered into such an agreement with the Union.

Article One of the collective bargaining agreement reserved to the Board all of its statutory powers. However, Article I, clause 21, expressly states that the statutes outlining the Board's powers "will not be used in any attempt to diminish employee rights under § 111.70 (MERA)." While sec. 118.22(2), Stats., is not among the statutory powers expressly reserved by the agreement, we conclude that the Board did not surrender its control over teacher employment by its failure to refer to that statute. Consistent with this, we conclude that, pursuant to clause 21, sec. 118.22 may not be used to diminish employes' [employees'] rights under MERA.

MERA authorizes a municipal employer and a collective bargaining unit representing municipal employes [employees] to bargain and reach a binding agreement on "wages, hours and conditions of employment." Dismissal of employes [employees], and establishment of a grievance procedure pertaining thereto, was held by this court to be within the proper scope of collective bargaining in Richards, 58 Wis.2d at 460a-460b.

Article Seven, section 6, clause 3, of the agreement between the Union and the Board states that a teacher will not be "disciplined" without "just cause and the approval of the administration." The arbitration panel, the trial court and the court of appeals all interpreted discharge of an employee to fall within the concept of "discipline." We agree with that interpretation.

The parties agree that the just cause standard is binding on the Board. The dispute is over who determines whether just cause exists. In entering into the agreement, the Board limited its statutory power to discharge teachers by agreeing it would only discipline a teacher "with the approval of the administration." It further agreed that it would not discipline or reprimand a teacher "without just cause."

The Board argues, and the trial court held, that this determination is exclusively reserved to the Board by sec. 118.22, Stats., and the collective bargaining agreement. While the discharged employee is entitled to file a grievance over the Board's action, review is limited to whether the Board's decision that just cause for discharge exists is supported by any credible evidence or was not arbitrary and capricious. According to the Board, such review is limited to the factual record relied upon by the Board in reaching the decision to discharge Mr. Fortney.

Mr. Fortney argues, and the court of appeals held, that if a teacher contends that just cause did not exist for his discharge, he is entitled to file a grievance pursuant to the procedures set forth in Article III of the agreement. An arbitration panel appointed pursuant to the grievance procedure must determine whether just cause for discharge existed in order to resolve the grievance. Because the language in the agreement is vague and indefinite as to exactly what procedures should be used to arrive at that determination, it is within the province of the arbitration panel, as the interpreter of the contract language, to devise such procedures as it considers necessary to reach a decision, as long as those procedures are compatible with the contract language and do not violate the law. Mr. Fortney argues that the conclusion of the arbitration panel that a de novo factual hearing was required to determine whether just cause existed for the discharge is a reasonable one under the contract, violates no law, and therefore must be affirmed.

In Dehnart v. Waukesha Brewing Co., 17 Wis.2d 44, 51, 115 N.W.2d 490 (1962), this court outlined the limited scope of judicial review of arbitration decisions:

"While this court may disagree with the interpretation of the contract reached by the arbitrator, we will not substitute our judgment for that of the arbitrator. The parties contracted for the arbitrator's settlement of the grievance and that is what they received.

"In United Steelworkers of America v. American Mfg. Co., 363 U.S. 564, 567, 80 Sup.Ct. 1343, 1346, 4 L.Ed.2d 1403, it is stated:

"`The function of the court is very limited when the parties have agreed to submit all questions of contract interpretation to the arbitrator. It is confined to ascertaining whether the party seeking arbitration is making a claim which on its face is governed by the contract. Whether the moving party is right or wrong is a question of contract interpretation for the arbitrator. In these circumstances the moving party should not be deprived of the arbitrator's judgment, when it was his judgment and all that it connotes that was bargained for.'"

Deference to arbitration decisions is particularly important in the area of public employment, where binding arbitration is set forth in MERA as an aid to labor peace. In Jt. School Dist. No. 10 v. Jefferson Ed. Asso., 78 Wis.2d 94, 112-13, 253 N.W.2d 536 (1977), which involved an arbitration decision resolving a dispute between a school board and a teacher covered under a collective bargaining agreement, this court stated:

"The court has no business weighing the merits of the grievance. It is the arbitrators' decision for which the parties bargained. In Dehnart v. Waukesha Brewing Co., Inc., 17 Wis.2d 44, 115 N.W.2d 490 (1962), this court adopted the Steelworkers Trilogy teachings of the court's limited function. The court's function is limited to a determination whether there is a construction of the arbitration clause that would cover the grievance on its face and whether any other provision of the contract specifically excluded it. . . .

"Our adherence to the Trilogy is in keeping with the strong legislative policy in Wisconsin favoring arbitration in the municipal collective bargaining context as a means of settling disputes and preventing individual problems from growing into major labor disputes. Secs. 111.70(3)(a) 5, 111.70(6), Stats.; Local 1226 v. Rhinelander, 35 Wis.2d 209, 216, 151 N.W.2d 30 (1967); Teamsters Union Local 695 v. Waukesha County, 57 Wis.2d 62, 69, 203 N.W.2d 707 (1973)."

We therefore must uphold the arbitrators' decision as long as it is within the bounds of the contract language, regardless of whether we might have reached a different result under that language, and does not violate the law.

Collective bargaining agreements arrived at under MERA, and statutes related to matters contained in such agreements, are to be harmonized wherever possible. Professional Police Ass'n, 106 Wis.2d at 316-17; Glendale Prof. Policemen's Asso. v. Glendale, 83 Wis.2d 90, 103-04, 264 N.W.2d 594 (1978). We conclude that harmonizing the collective bargaining agreement provisions with the Board's power to discharge set forth in sec. 118.22 (2), Stats., leaves the Board with the exclusive right to discharge an employe, but requires that just cause exist for the discharge. If the employe contends there was no just cause for discharge, he may process a grievance through the procedure contained in the agreement. If that grievance goes to arbitration, the arbitrators, under the terms of the agreement, may make an independent determination of whether there was just cause for the discharge, relying on whatever procedures they deem necessary to reach that determination. If the parties disagree with the procedure employed by the arbitrators, their remedy is to change the language of the agreement. In view of the broad powers of contract interpretation vested in arbitrators, their interpretation of the vague language governing arbitration procedure contained in this agreement should be upheld as the parties' bargain.

The Board and the trial court gave a great deal of significance to the fact that the Board authorized the fact finding procedure carried out by Mr. Langer prior to arriving at its decision to discharge Mr. Fortney. While such a procedure was sufficient to protect Mr. Fortney's constitutional right to due process, it does not prevent Mr. Fortney from pursuing his additional rights under the collective bargaining agreement.

The agreement contains a step-by-step procedure for the processing of grievances. The proceedings conducted by Mr. Langer are not a substitute for those procedures. Mr. Fortney's counsel stated, in a letter to the Board, that while Mr. Fortney was willing to participate in the fact finding process conducted by Mr. Langer, he was expressly reserving his right to invoke the contractual grievance procedure if the Board took any action against him. When the subject of the "just cause" standard for discharge came up at the hearing, both Mr. Langer and counsel for the Board stated that the language of the agreement was irrelevant to that hearing. At the commencement of the hearing held June 18, 1979, Mr. Langer expressly stated:

"I don't propose to construe this contract and apply the contract language at this point. I believe that's something that is a province of another tribunal."

We recognize that public policy militates in favor of maintaining a high degree of local control over educational decisions. Vesting broad authority in local school boards is a proper way of fulfilling this goal. Our decision in this case furthers that policy, recognizing and giving effect to provisions of a collective bargaining agreement voluntarily negotiated and agreed to by the Board and a Union representing employes [employees] of the local school district. While the Board is given certain powers in chs. 118 and 120, Stats., MERA also grants the Board the authority to modify those statutory powers, where a school board deems this to be advantageous in the maintenance of labor peace, by means of a collective bargaining agreement. Obviously, in the future, the Board may seek to modify the provisions at issue here through the collective bargaining process.

An argument that the arbitrators' decision should be vacated on constitutional grounds is urged upon us by the Wisconsin Association of School Boards, Inc., (hereinafter WASB) appearing as amicus curiae. This argument relies on our recent decision in Professional Police Ass'n. v. Dane County, 106 Wis.2d 303, where we held that an arbitration decision will be vacated if it enforces a provision in a collective bargaining agreement which violates the Wisconsin Constitution, Professional Police Ass'n. 106 Wis.2d at 315. WASB argues that Article X, sec. 1, of the Wisconsin Constitution reserves certain powers to school boards, and that the collective bargaining agreement, as construed by the arbitrators, violates this provision, requiring that the decision be vacated.

This case, however, is a far different one than was before this Court in Professional Police Ass'n. That case involved a constitutional provision providing for the office of sheriff. Prior decisions of this court held that the sheriff, under common law, had certain powers and duties in his relationship to the courts which were incorporated into the constitution. The sheriff cannot be divested of those powers and duties by statute. In Professional Police Ass'n, this court held that the common law powers and duties of the sheriff could likewise not be limited or abrogated by a collective bargaining agreement entered into by a county and a union representing deputy sheriffs. Professional Police Ass'n., 106 Wis.2d at 315.

The provision at issue here, however, is not one which incorporates an ancient common law office, possessing defined powers and duties, into the constitution. Public instruction and its governance had no long-standing common law history at the time the Wisconsin Constitution was enacted. Furthermore, Article X, sec. 1, explicitly provides that the powers and duties of the school superintendent and other officers charged by the legislature with governing school systems "shall be prescribed by law." Because the constitution explicitly authorized the legislature to set the powers and duties of public instruction officers, Article X, sec. 1 confers no more authority upon those officers than that delineated by statute. Therefore, consistent with our holding that the arbitrator's decision and award violates no statutory provision relating to the powers and duties of the Board, we hold that it does not violate the Wisconsin Constitution.

In its petition for review the Board argues that when the arbitrators decided to hold a de novo hearing, they should have permitted the Board to bring in new charges against Mr. Fortney in addition to the charges that provided the basis for his discharge by the Board. This the arbitrators refused to do. "The manner of conducting the arbitration proceeding after the arbitrator is selected and until the award is issued is left largely within the control of the parties and the arbitrator." Layton School Art and Design v. WERC, 82 Wis.2d 324, 343 n. 18, 262 N.W.2d 218 (1978).

We quote with approval the following language by the court of appeals in this case upholding the procedure adopted by the arbitrators:

"The arbitrators' limitation on the evidence to be introduced was reasonable. When the school board adopted the hearing examiner's findings, it made clear that Fortney's discharge was based on the nine charges found substantiated by the examiner, and that the other charges would not warrant discharge even if true. Evidence relating to other instances of misconduct was not relevant to the charges for which Fortney was discharged. The arbitrators acted reasonably in not permitting the school board to lodge new charges against Fortney at the arbitration hearing when they did not form the basis for his discharge." (Slip Op. at 12-13).

We hold that the decision of the arbitrators to limit the scope of the de novo hearing to the specific charges for which the Board discharged Mr. Fortney was proper under the contract.

In summary, we hold that the decision by the arbitration panel to conduct a de novo hearing as to whether just cause existed to discharge Mr. Fortney, limited to the charges upon which the Board issued its discharge decision, followed by the conclusion that no just cause existed, was within the arbitrators' authority. The arbitrators' decision did not reflect a perverse misconstruction of the terms of the collective bargaining agreement nor was it violative of any statutory or constitutional provision. We therefore affirm the Court of Appeals.

By the Court. — The decision of the court of appeals is affirmed.
