Appellants contend that the statutory language within R. C. 4112.05(B), concerning efforts to resolve alleged discriminatory practices by conciliation, is a jurisdictional prerequisite to the proper issuance of a complaint by the Ohio Civil Rights Commission.
R. C. 4112.05(B) sets forth specific procedures to be followed by the commission and, in pertinent part, states:
“Whenever it is charged in writing and under oath by a person, referred to as the complainant, that any person, referred to as the respondent, has engaged or is engaging in unlawful discriminatory practices, or upon its own initiative in matters relating to any of the unlawful discriminatory practices enumerated in division (A), (B), (C), (D), (E), (F), (I), or (J) of Section 4112.02 of the Revised Code, the commission may initiate a preliminary investigation. '* * * If it determines after such investigation that it is probable that unlawful discriminatory practices have been or are being engaged in, it shall endeavor to eliminate such practices by informal methods of conference, conciliation, and persuasion. # # * If, after such investigation and conference, the commission is satisfied that any unlawful discriminatory practice of the respondent will be eliminated, it may treat the complaint as conciliated, and entry of such disposition shall be made on the records of the commission. If the commission fails to effect the elimination of such unlawful discriminatory practices and to obtain voluntary compliance with Chapter 4112 of the Revised Code, or, if the circumstances warrant, in advance of any such preliminary investigation or endeavors * * * the commission shall issue and cause to be served upon any person or respondent a complaint stating the charges in that respect and containing a notice of hearing before the commission * *
By drafting R. C. 4112.05(B) in the above manner, the General Assembly established definite guidelines for the *181commission to follow prior to issuance of a complaint. First, the commission must make a preliminary investigation to ascertain whether unlawful discriminatory practices exist or were engaged in. Second, if such investigation results in an affirmative finding by the commission, it “shall endeavor to eliminate such practices by informal methods of conference, conciliation, and persuasion.” (Emphasis added.) The commission is authorized to issue a complaint stating the charges and giving notice of a hearing only when efforts at conciliation have been completed and have failed to remedy the problems by voluntary compliance.1 When it employed the chosen language in E. G. 4112.05(B), concerning pre-complaint directives for conciliation, it is clear that the General Assembly intended a completed attempt at conciliation to be a condition precedent to the issuance of a complaint.
The commission’s own rules and regulations support the statutory requirement that an accomplished effort at meaningful conciliation precede the complaint. Bule 5.02 states:
“Where the facts indicate that it is probable that any unlawful discriminatory practices have been or are being engaged in, the director shall immediately refer the matter to the commission with a recommendation for proceeding with conciliation. If the commission determines such probable cause does exist, the commission shall instruct the Director to endeavor to eliminate all unlawful discrim*182inatory practices by conference, conciliation and persuasion.”
Rule 9.01 provides, in part:
“After the commission determines that it is probable that any unlawful discriminatory practices have been or are being engaged in against complainant or others and after the commission fails to effect the elimination of such unlawful discriminatory practices by conciliation * * * the commission shall issue and cause to be served upon all parties thereto or their attorneys of record, if any, a complaint containing a notice of hearing before a hearing examiner. ’ ’
Under federal law, the Equal Employment Opportunity Commission (EEOC) was established to prevent unlawful employment practices. The EEOC operates under a statutory framework similar to R. C. 4112.05(B) in'relation to procedures prior to the intiation of an action in court.2 As can be seen, Section 2000e-5(b), Title 42, U. S. Code, employs mandatory language identical to R. C. 4112.-05(B) concerning efforts by the EEOC to achieve voluntary compliance after unlawful practices are found to exist.
*183In construing the relevant language in Section 2000e-5(b), the federal courts have consistently held that the EEOC may not initiate a civil action without first attempting, in good faith, to correct the situation by conciliation. In Equal Employment Opportunity Comm. v. Griffin Wheel Co. (N. D. Ala. 1973), 360 F. Supp. 424, the court stated, at page 426:
“The inability of the commission to secure from defendant a conciliation agreement acceptable to the commission is a prerequisite * * * which must be satisfied before the commission can file a civil action. In amending Title VII in 1972 to allow the commission to maintain suit on its own behalf, Congress emphasized the duty of the commission to make a good faith effort to secure voluntary compliance through conciliation prior to bringing suit; and the fulfillment of this duty is necessary before a district court can entertain suit by the commission. Being jurisdictional in nature, the complaint must at least allege in the statutory language that ‘the commission has been unable to secure from the respondent a conciliation agreement acceptable to the commission.’ ”
See, also, Equal Employment Opportunity Comm. v. Western Electric Co. (D. Md. 1973), 364 F. Supp. 188; Equal Employment Opportunity Comm. v. E. I. DuPont de Nemours & Co. (D. Del. 1974), 373 F. Supp. 1321; Equal Employment Opportunity Comm. v. Container Corp. of America (M. D. Fla. 1972), 352 F. Supp. 262; Equal Employment Opportunity Comm. v. United States Pipe & Foundry Co. (N. D. Ala. 1974), 375 F. Supp. 237; Equal Employment Opportunity Comm. v. Hickey-Mitchell Co. (C. A. 8, 1974), 507 F. 2d 944, in which the courts have determined that an unsuccessful effort at conciliation is a “jurisdictional prerequisite” or “condition precedent” to the commission’s initiation of a civil action.
What further emerges from these cases is that attempted conciliation must precede adversary proceedings not only due to the language within Section 2000e-5(b), but because voluntary compliance enables the commission to better *184carry out its responsibilities. Thus, negotiation must be the primary mode of enforcement; otherwise, the commission’s energies would be wasted at trial, and implementation of Title YII objectives would be frustrated.3 Such a rationale also applies to the Ohio Civil Bights Commission and its duties under B. C. Chapter 4112.
It is our conclusion that, pursuant to B. C. 4112.05(B), a completed and unsuccessful attempt by the Ohio Civil Rights Commission to eliminate unlawful discriminatory practices by conference, conciliation or persuasion is a jurisdictional prerequisite to the issuance of a complaint by the commission, except where circumstances warrant the issuance of a complaint directly upon receipt by the commission of knowledge of the unlawful discriminatory practices alleged therein. In the case at bar, the complaint stated that efforts at conciliation had begun, but were not completed, with respect to Bepublic Steel, and had not even begun with the unions. Therefore, the commission lacked the jurisdiction to issue a complaint under B. C. 4112.05(B).
The commission contends, however, that it is not about to exercise judicial or quasi-judicial power and that appellants have an adequate remedy at law; thus, it asserts that conditions which warrant the granting of a writ of prohibition are not present in this case.4
Under prior decisions of this court, proceedings of administrative agencies are considered quasi-judicial if there is notice, a hearing and an opportunity for introduction of evidence. M. J. Kelley Co. v. Cleveland (1972), 32 Ohio St. 2d 150, 290 N. E. 2d 562; Zangerle v. Evatt (1942), 139 Ohio St. 563, 41 N. E. 2d 369. An examination of the *185provisions of E. C. 4112.05 reveals that proceedings before the commission meet the above criteria. The complaint provides for notice of a hearing before the commission. E. C. 4112.05(B). At that hearing, the party charged in the complaint may examine and cross-examine witnesses nnder oath, and introduce evidence to refute the alleged unlawful practices. E. C. 4112.05(C) and (D).
Additionally, whether or not the availability of an appeal from the commission’s finding5 constitutes an adequate remedy at law is immaterial in light of the commission’s unambiguous lack of jurisdiction and the principle announced in State, ex rel. Adams, v. Gusweiler (1972), 30 Ohio St. 2d 326, 285 N. E. 2d 22.
For the foregoing reasons, the judgment of the Court of Appeals is reversed, and the writ prayed for is allowed.
Judgment reversed and writ allowed.
