The respondent is president of the council of the city of St. Louis. On the ninth of August, 1897, an alternative writ of mandamus was issued by the circuit court, city of St. Louis, commanding the respondent to sign house bill number 59, being an ordinance granting certain rights, privileges and franchises to the relator, or show cánse why he should not. To which writ, for such cause, the respondent made return, in substance, that said house bill number 59 never was read on three different days before the council, of the municipal assembly as required by the charter. On the hearing it appeared from the journal that the bill was read in the council “on three different days, May 25th, May 28th and July 20,” and oral testimony was introduced, over the objections of relator, tending to prove that the bill “was read at length in the council once on May 25th; by its title on May 28th,' again by its title on July 13th, and at length in committee of the whole on July 20th, and that there was no other reading before its alleged passage.” Thereupon the court found for the respondent, dismissed the relator’s bill, rendered judgment in respondent’s favor for costs, and the relator appealed to the St. Louis Court of Appeals, where the judgment of the circuit court was reversed, Judge Biggs dissenting, and deeming the decision of the majority of the court in conflict with the decision of this court in State ex rel. v. Stone, 120 Mo. 428, the case was certified here for determination.
*444In State ex rel. v. Stone it was held that mandamus will not issue to the Governor to compel the performance of any duty pertaining to his office, prescribed by law, and it is contended for respondent that the same rule applies to the president of the council of the city of St. Louis, under the requirement of the Constitution, article III, that “The powers of government shall be divided into three distinct departments — the legislative, executive and judicial — each of which shall be confided to a separate magistracy, and no person or collection of persons charged with the exercise of powers properly belonging to one of those departments shall exercise any power properly belonging to either of the others except in the instances in this Constitution expressly directed or permitted.” The contention is that the respondent as president of the council in signing a bill passed by the municipal assembly in order that it may become an ordinance of the city, is charged with the exercise of a legislative power over which the judicial department has no control.
By the charter of the city of St. Louis its legislative power is vested in a council and a house of delegates styled the “Municipal Assembly of the City of St. Louis” (sec. 1). The council consists of thirteen members, one of whom chosen on a general ticket by the qualified voters of the city for four years is “president” (secs. 2 and 8). It is further provided by the charter that “No ordinance shall be passed except by bill, and no bill shall be so amended in its passage through either house as to change its original purpose. Bills may originate in either house, and may be amended or rejected by the other, and every bill shall be read on three different days in each house. No bill shall be considered for final passage unless the same has been reported upon by a committee”.......(sec. 13). No bill shall become an ordinance unless on its *445final passage the majority of the members elected to each house vote in its favor and the vote be taken by yeas and nays and the names of the members voting for and against the same be entered on the journal (sec. 16), and when a bill shall have thus attained its final passage the charter provides that it shall not become an ordinance “until the same shall have been signed by the presiding officer of each of the two houses in open session; and before such officer shall affix his signature to any bill, he shall suspend all other business, declare that such bill will now be read, and that, if no objections be made, he' will sign the same to the end that it may become an ordinance. The bill shall then be read at length, and if no objection be made, he shall, in the presence of the house in open session, and before any other business is entertained, affix his signature, which fact shall be noted on the journal, and the bill immediately sent to the other house. When it reaches the other house, the presiding officer shall announce the reception of the bill and the same proceeding shall thereupon be observed in every respect as in the house in which it was first signed. If in either house any member shall object that any substitution, omission or insertion has occurred so that the bill proposed to be signed is not the same in substance and form as when considered and passed by the house, such objection shall be passed upon by the house and if sustained, the presiding officer shall withhold his signature” (sec. 22). Having thus received the signature of the president of the council it must then be presented to the mayor for his approval or disapproval before it can become law (sec. 23).
That the municipal assembly in thus making a law by virtue of the power vested in it under the Con*446stitution and laws of the State, exercises powers properly belonging to the legislative department of the State, is beyond question. Taylor v. Carondelet, 22 Mo. 105; St. Louis v. Foster, 52 Mo. 513; State v. Vic de Bar, 58 Mo. 395; Moore v. Gape Girardeau, 103 Mo. 470; Union Depot v. Railroad, 105 Mo. 562; Jackson v. Railroad, 118 Mo. 199; 2 Dill. Mun. Corp. [2 Ed.], sec. 245. That the respondent' as president of the council is a person charged with the exercise of legislative power is evident, and that the courts will not interfere with either of the other co-ordinate departments of the government in the exercise of their powers, except to enforce mere ministerial acts 'required by law to be performed by some officer thereof, as to the performance of which the law leaves the officer no discretion, is the well settled law of the land, universally recognized since the decision in Marbury v. Madison, 1 Cranch, 64, in which Marshall, Chief Justice, speaking for the Supreme Court of the United States declared the rule, that whether mandamus would lie or not is to be determined “not by the office of the person to whom the writ is directed, but by the nature of the thing to be done.” Some diversity of opinion however has arisen since that decision' in 1803 in regard to the office of Governor of a State. In the courts of many of the States it has been held that all the duties imposed upon the Governor by law are executive, to the performance of none of which can he be coerced by mandamus. In others it has been held that while he is independent as to all acts pertaining to his executive office, nevertheless he is subject to the law like every other individual in the State with respect to all duties of a purely ministerial character as distinguished from those belonging to his executive office. 14 Am. and Eng. Ency. of Law, p. 143, sec. 3, note 1.
*447In the recent case of State ex rel. v. Stone, 120 Mo. 428, the leading cases upon this question are collated, from an examination of which the court found that the weight of authority was in favor of the first proposition, and considering his official oath under the Constitution, and that in addition to the provisions thereof hereinbefore quoted it is further provided by that instrument, that “the* supreme executive power shall .be vested in a chief magistrate who shall be styled the Governor of the State of Missouri,” who “shall perform such duties as may be prescribed by law,” and “take care that the laws are faithfully executed,” it was held that “any duty prescribed by law for the Governor to perform is as much part and parcel of his executive duties as though made so by the most solemn language of the Constitution itself,” and hence that li man damns will not issue to the Governor to compel the performance of any' duty pertaining to his office whether political or merely ministerial.” The office of president of the council of the city of St. Louis is the creature of.delegated statutory power; his power is measured by the terms of the charter, and nothing can be found in the nature of the office thus created that brings it within the principle announced in this case, or of any of the numerous cases therein cited, or which may elsewhere be found. So far as the duties of the office are legislative in character, he is free from the control and supervision of the courts; so far as they are merely ministerial in character he is subject like other ordinary mortals to such control as may in a proper case be exercised by the courts by means of the writ of mandamus. So that the controlling question in this case is whether the act sought to be 'enforced is or is not a mere ministerial act ? ‘ ‘A ministerial act is one which a public officer is required to perform upon a given state of facts in a prescribed *448manner in obedience to the mandate of legal authority, and without regard to his own judgment or opinion concerning the propriety or impropriety of the act to be performed.” Merrill on Mandamus, sec. 30; Marcum v. Com’rs, 42 W. Va. 263, and cases cited.
The respondent is a public officer of the city of St. Louis, who is required to perform the act of signing his name to a bill passed by the municipal assembly,' at that stage of the procedure in that body when the bill shall have reached him for that purpose in the manner prescribed by the charter. Is he by the charter, that legal authority from which he derives all his power in the premises, invested with any discretion whatever as to whether he will or will not then sign the bill? This is the crucial question, and is answered by the terms of the charter itself. The state of facts is therein given in which he shall, and in which he shall not sign the bill. “If no objection be made he shall in the presence of the house, in open session and before any other business is entertained affix his signature. “If any member shall object that any substitution, omission or insertion has occurred so that the bill proposed to be signed is not the same in substance and form as when considered and passed by the house such objections shall be passed upon by the house and if sustained the presiding office shall withhold his signature,.” The conditions upon which he shall either sign or withhold his signature,, are here prescribed in unmistakable terms. ■ If no objections be made “he shall sign.” If objections are made and sustained by the house he “shall withhold his signature,” and conversely, if objections are made and not sustained by the house, he must sign, and this he must do without regard to his own judgment or opinion concerning the propriety or impropriety of the act. In the language of the charter his act has to do with a bill which has *449been “considered and passed.” When the president is called upon to perform this act the time for legislative deliberation has passed. The only legislative discretion left at all is left in the house, and that is limited to determining whether the bill which the president is called upon to sign is the identical bill which had been “considered and passed” and when this discretion has been exercised and the question affirmatively determined, nothing is left to be done but the mere physical act of signing the bill, and this was precisely the status of the bill when the president refused to sign in this case. This limitation and the proceedings under it easily distinguish this case from that of Ex parte Echols, 39 Ala. 698, upon which reliance seems to be placed to support the conclusion reached by the learned circuit judge. In that case mandamus to the Speaker of the House of Representatives of the General Assembly of the State compelling him to send to the Senate a bill which he had decided had not passed and in which decision on appeal he was sustained by the House, was refused' — ■ for the obvious reason that the House having sustained the decision of the Speaker, to constrain him to do an act in contravention of its decision in a matter within its legislative discretion, would be an unwarrantable interference with the legislative powers of that body. In this ease to grant the writ is to constrain the president to do an act in compliance with the decision of the council in a matter upon which it had exercised its legislative discretion, and thereby to sustain the legislative power of that body, and the independence of the legislative department of the government in all matters within its jurisdiction; to refuse.it would be to subordinate that power to the judgment of its presiding officer and practically to invest him with a power of *450veto upon its legislation not granted in the charter. Therefore the writ should have been granted. If this conclusion from the premises stated be correct, consideration of the other questions discussed in the briefs of counsel is unnecessary, and in view of the extended consideration which the case has received in the opinions of the judges of the court of appeals, we deem further elaboration also unnecessary. The judgment of the circuit court will be reversed, and the cause remanded with directions to that court to issue a peremptory writ of mandamus requiring the respondent to sign house bill number 59.
