This is a proceeding commenced in this court by mandamus to compel the respondents who constitute the State Board of Health to issue to Ur. Hathaway, the relator, a certificate to practice medicine in this state.
1. The first question is one of pleading. The petition for the writ, after alleging that the relator was a graduate of a medical college, in good standing, and that *25he presented to the respondents his diploma and the respondents found the diploma to be genuine, and the college in good standing, proceeds to state in substance, that the respondents refused to issue to him a certificate “upon the alleged and only ground that relator’s method of advertising himself as a specialist in the treatment of private, blood and skin diseases was dishonorable and unprofessional, and that by such advertising he was guilty of unprofessional and dishonorable conduct, but relator denies that he has been guilty of any unprofessional or dishonorable conduct in and by such advertising or in any other manner, and relator charges the truth to be that said defendants, as such board, have knowingly issued certificates to divers physicians and surgeons who are, and claim to be, specialists and advertise as such in the same manner as relator,” and that the board, “ in refusing to grant to him a certificate, were and are actuated, governed and controlled by prejudice, bias caprice and partiality, and wantonly refuse to issue such certificate to relator,” etc. These statements concerning the reason why the board refused to issue a certificate, and bias and prejudice on the part of the board, were not set forth or recited in the alternative writ.
To the writ the secretary of the board, for want of means to engage counsel it seems, made return. This return concedes that the relator had and held a diploma from a medical institution in good standing, and it goes on to state that the relator was heard in person, and by counsel, and on the eleventh of July, 1889, the board refused him a certificate because he was found guilty on charges duly preferred of unprofessional and dishonorable conduct in the habitual publication of advertisements, which in the opinion of the board tended, and were designed, to mislead and deceive the public and impose upon sick and credulous persons by impossible claims of the treatment of diseases, and for the further reason that he was then engaged in the practice of medicine without a certificate, and in defiance of the law. The *26return further states that the respondents, “in their further endeavor to faithfully and impartially discharge their sworn duty under the law,” were guided by the ruling of this court in the Granville case, 83 Mo. 123.
To this return the relator made answer in which he set up, among other things, the matters stated in the petition, and which were not recited in the alternative writ. The respondents filed no reply to this answer and the claim is now made that those matters stated in the answer stand admitted, and that á peremptory writ should be issued on the face of the pleadings.
The statute, it is true, provides in substance that the respondent shall make return to the alternative writ; that the relator must plead to or traverse the return ; and that the respondent shall then reply, take issue or demur. Still the alternative writ is, in our practice, the first pleading, and it takes the place of a petition in an ordinary common-law action. Hambleton v. Town of Dexter, 89 Mo. 190 ; High on Ex. Leg. Rem., sec. 537. The writ should set forth all the matters stated in the petition, so that the respondent will be informed of the grounds upon which the relief is asked. State ex rel. v. Everett, 52 Mo. 94 ; High on Ex. Leg. Rem., sec. 538. In view of the fact that the pleadings are informal on both sides, and of the further fact, that the return was evidently made in view of the matters stated in the petition, we are of the opinion no undue advantage should be awarded the relator because he has set up matters in his answer which were stated in the petition and should have been recited in the writ.
When we look to the relator’s pleadings, taken all in all, we find that he asserts in substance that the board denied him a certificate because he advertised his business in a manner which the board found to be unprofessional and dishonorable, when he was guilty of no such conduct, and that the board in refusing him a certificate acted from prejudice, bias and partiality. On the other *27hand the respondents say they refused him a certificate because he was found guilty of dishonorable and unprofessional conduct in his method of advertising and because he persisted in violating the law by practicing medicine without a certificate, and that in refusing the certificate they endeavored faithfully and impartially to discharge their duties, guided by the former ruling of this court. While the return contains no specific denial in terms of the matters stated in the petition and writ, still the matters thus stated in an affirmative form in the return do deny all the matters of substance alleged by the relator, and this form of a denial must be held to be sufficient (Jordan v. Buschmeyer, 97 Mo. 97), and especially so when, as here, there has been no effort to bring the pleadings to a formal presentation of the issues.
2. The facts bearing upon the merits of this case as gathered from the pleadings and exhibits before us are these : Hathaway and Dr. Boyd began the practice of medicine in this state as specialists without having first procured certificates under the statute concerning the practice of medicine and surgery. W e infer from what is said that prosecutions had been commenced against them, or complaints lodged before the board of health. Under these circumstances they applied to the board for certificates. They presented in due form genuine diplomas issued by medical institutions in good standing ; but the board after hearing them in person and by counsel made the following order on the eleventh of July, 1889 : “ After due deliberation and upon full consideration of the matter, the board by unanimous vote refused certificates to * * * James N. Hathaway, for unprofessional or dishonorable conduct, consisting in the publication by them of advertisements in the public press of St. Joseph, Missouri, during the present year, said advertisements in the opinion of the board being of a character that tended to mislead and deceive the public, to wrongfully impose on the fears, weakness or *28ignorance of the sick or credulous, and to defraud the people by false and impossible claims in regard to the treatment of disease.”
Hathaway again appeared before the board in person and by attorney on the twenty-first of January, 1890, when the board made this order: “After due consideration of the matter, the board by unanimous vote declined to accede to the request and refused a certificate to Hathaway, for unprofessional or dishonorable conduct.”
Between the dates upon which the foregoing orders were made, Boyd modified his advertisement so as to meet the approval of the board, and a certificate was issued to him ; but the modified advertisement presented by the relator was not satisfactory to the board. The answer of the relator gives a copy of these modified advertisements, but the record does not contain a copy of the advertisements upon which the board made its first ruling.
By section 6878, Revised Statutes, 1889, it is enacted that: “The State Board of Health may refuse certificates to individuals guilty of unprofessional or dishonorable conduct, and they may revoke certificates for like causes, after giving the accused an opportunity to be heard in his defense before the board.”
This section of the statute imposes upon the board duties which are quasi-]udicial in their character. The question whether the applicant is guilty of unprofessional or dishonorable conduct calls for the exercise of judgment and sound discretion. It is a question as to which the board must hear the evidence and pronounce a conclusion. The principle of law is well settled that mandamus will not lie to review official acts which require the exercise of judgment and discretion. Mandamus may be awarded for the purpose of requiring such officers to proceed and act upon such matters, but does not lie to direct or control the conclusion to be *29reached. The respondents heard the relator’s application and decided that he was not entitled to a certificate, because guilty of unprofessional and dishonorable conduct, and that decision cannot be brought here for review by this proceeding. The case of State ex rel. Granville v. Gregory, 83 Mo. 123, is in point and disposes of the question in hand. Other courts have expressed the same views under statutes quite like our own. State ex rel. v. State Medical Examining Board, 32 Minn. 324; People v. Dental Examiners, 110 Ill. 180. See also Allbutt v. General Council of Medical Education and Registration, 23 Law Rep. 400, Queen’s Bench Liv.
There are some limitations upon the rule just stated ; for, if the. board of health should exercise its powers with manifest injustice, then the courts may, and will, control the abuse of authority by the writ of mandamus. Illinois State Board of Dental Examiners v. People, 13 N. E. Rep. 201. As the legislature has not defined what is “unprofessional or dishonorable conduct,” those words must be understood to mean such conduct as would in common judgment be deemed unprofessional or dishonorable. In determining whether a party is guilty of such conduct there is a broad field for the exercise of judgment and discretion by the board, and within which the finding of the board is conclusive. The board of health has no right to prescribe a code of medical ethics, and then declare a breach of that code unprofessional and dishonorable conduct; nor has it the right or power to deny to physicians the right to advertise their profession in the public press. The respondents make no claims of any light to do either of these things. Their claim is that advertisements which tend to mislead and deceive the public constitute unprofessional and dishonorable conduct, and in this they are within the purview of the law. If, however, a physician will, in his advertisements, throw out inducements to patients to submit to *30treatment, then the matter is within the exclusive jurisdiction of the board. We are not furnished with a copy of the advertisements upon which the board made its first ruling. The burden, however, is upon the relator to show that the ruling of the board is manifestly unjust.
The proof offered to show prejudice and bias on the part of the board is the fact that a certificate was finally issued to Boyd but refused to relator. Boyd modified his advertisement so as to avoid the objectionable features and meet the views of the board, but this the relator did not do. We see no evidence of prejudice on the part of the board. Indeed, it must be remembered that the relator came to this state and began the practice of medicine without any certificate. So long as he thus knowingly bid defiance to the law he was not entitled to one. -' The board of health is charged with the performance of important discretionary duties, and the performance of their duties will not be hampered by mandamus until a case of manifest injustice is shown; The relator has not made out such a case. Peremptory writ denied.
All concur.
