The appellant filed, in the superior court of King county, án affidavit and petition for a writ of mandamus, to be issued against the board of dental examiners of the state of Washington, and the members -thereof, commanding them to issue to appellant a license to practice dentistry in the state of Washington, alleging in the petition that they had refused to grant the same to appellant unless he would sign a certain code of ethics which had been prepared by the said board of dental examiners, and alleging that he was qualified for admission, etc. The respondents answered, denying the allegations of the petition, and affirmatively alleging that there had been no discrimination against appellant^ but that his failure to be admitted was by reason of his failure to- pass the examination which all applicants were subjected to-. The appellant applied to- Judge Hatch for an 'order on the respondents to produce the questions, answers, and other documents relating to the examination, and the case was continued for that purpose. When the cause was again called, Judge Rudkin was the presiding judge, and, the respondents having failed to produce the questions, answers, and other documents relating to the examination, *327the court declined to enforce the order, holding that such testimony could not legally be admitted in this case, and that the only question for the jury to determine was whether or not the license was withheld by the examining board because the applicant would not subscribe to the code of ethics. The case was tried on the issues thus narrowed, and, there being no testimony tending to support the allegation relied upon, the cause was withdrawn from the jury, and the application dismissed. Trom the judgment of dismissal, this appeal is taken.
As to the first error—in refusing to- enforce the order of Judge Hatch in relation to the testimony asked for—if Judge Hatch had continued to sit in the case, when the testimony was offered, and if it had appeared to the judge that it was not competent testimony under the pleadings, he would have had a right to reject it nothwithstanding his former order. No further limitations could be placed upon the power of Judge Rudkin, who succeeded him in the trial of the cause; and, as we view the law on this subject, the admission of such testimony would have constituted reversible error.
On the main proposition in the case—the right of the court to interfere with the discretion of the examining board—quite an array of authority is cited, and the usual discussion in such cases is indulged in. But it seems to us that the confusion that arises in the discussion of this question arises more from the inaccurate terms which are used by the law writers than from any inherent difficulty in the law itself. The general rule is well established that the courts cannot review the discretion which has by law been vested exclusively in inferior tribunals, and mandamus will therefore not lie to* compel the performance of acts or duties which necessarily call for the exercise of discretion on the part, of the officer or board at whose hands their *328performance is required; because tbe state has, as in tbis instance, determined upon and specified tbe officers upon whose judgment on tbe questions submitted to them tbe state is willing to rely. Taking tbe case at bar for an example, if a record of tbe. examination bad been produced in court, witb tbe questions, answers, and credits given to each question, who would determine whether or not a particular answer bad received a sufficient credit ? Certainly not. tbe jury, for they are not presumably competent to pass a proper judgment on such subjects. Not tbe judge, for bis qualifications do not embrace, or at least require, an expert knowledge of tbe science of dentistry. Expert witnesses could not be properly permitted to testify, for tbe reason that tbe state has already designated and empowered experts to pass upon these questions, presumably by reason of their recognized qualifications.
But, notwithstanding tbis, it is equally well established that courts, will compel by mandamus tbe honest performance of official duty, and if, under pretense of exercising, discretion, tbe power is exercised witb manifest injustice or is grossly abused, or duty is avoided, tbe courts will grant relief. Tbe action of tbe court must, in reality, be based upon tbe assumption that tbe inferior tribunal bas refused to- exercise tbe discretion with which it is clothed; because1, if it acts arbitrarily or fraudulently, or through unworthy or selfish motives, or conspires against tbe rights of individuals, under tbe law, and therefore against tbe law itself, it bas not strictly, as is frequently said, “abused its discretion”—a term which is responsible for some confusion of ideas on tbis subject-—but in contemplation .of law, it bas not exercised its discretion at all, but bas sought to substitute arbitrary and fraudulent disposition and determination of tbe question submitted, for tbe honest discretion demanded by tbe law. In such cases tbe law will, by *329mandamus, compel the tribunal to act honestly and fairly, or, in other words, to exercise Us discretion; and, when this distinction is kept in mind, the seeming difficulties which have surrounded this question, and which have caused so much discussion, disappear.
But, in the light of the record in this case-, these abstract principles are scarcely involved; for, while it is at least theoretically true that there is no wrong without a remedy, there is no allegation of any wrong in the petition in this case upon which the appellant was denied a hearing. The application for the writ, after setting forth the qualifications of the applicant and his admission in other states to the practice of dentistry, and his application to practice in this state, alleges, in paragraph 10, as follows:
“That the said defendants, disregarding their duties and obligations as dental examiners under the laws of this state, wrongfully and unlawfully demanded of said Edwin J. Brown, when he presented himself for examination, that the said Edwin J. BroWn sign and acknowledge a certain unlawful contract with the said board of dental examiners in consideration of his being permitted by said defendants to take said examination and receive a license to practice dentistry in this state, which said proposed contract is in words and figures as follows, to wit, . . .” (setting forth the contract and code of ethics.)
The following section (11) is as follows:
“That the said Edwin J. Brown refused to sign and acknowledge said proposed immoral and unlawful contract, and demanded that said defendants act upon the merits of his examination and his qualifications to practice dentistry in accordance with their duty and authority under the laws of this state, and that his name be registered as a licensed dentist by said board, and that a certificate be issued to him signed by the president and secretary of such board, in accordance with the statutes in such case made and provided.” *330And those are all the allegations of fraud there are in the complaint or petition. It is true, respondents are charged with fraudulently refusing, but this is the specified fraud, for section 12 proceeds: “That the said defendants, for the reasons aforesaid, wrongfully and fraudulently refused to register his name,” etc. So that, when this allegation of fraud, by refusing the license because the applicant would not sign the code of honor, absolutely failed to be established by proof, there was no other course left the court than to take the ease from the jury and dismiss the action.
The authorities which the appellant cites to this court are simply to the effect that the court will compel an inferior tribunal tO' exercise its discretion. The first ease cited by appellant, Illinois etc. Dental Ex. v. People ex rel. Cooper, 123 Ill. 227, 13 N. E. 201,- is where the-whole controversy was whether a certain college, at which the applicant had graduated, was a reputable college, the law providing that it was the duty of the board of dental examiners, upon the application of a person with a certificate from a reputable college, to- pass such applicant without examination. In that case the board refused to determine the question of whether the college was reputable or not, but, submitted that question h> a. society of dentists, many of whom it was alleged (and-was not disputed) were not citizens of the state of Illinois; and the court very properly held that in this the board of denial examiners of the state of Illinois refused to' exercise their discretion; that the duty to issue the license was purely a ministerial one, after the question of the reputation of the college was determined. The other cases cited are along the same line, and none of them, as we view them, are applicable to the questions involved in this case; under the pleadings presented. The constitutionality of the law *331has been, decided adversely to appellant’s contention in several cases by this court.
There appearing to be no, error in the record, the judgment will be affirmed.
