delivered the opinion of the Court—Cope, C. J. and Norton, J. concurring.
This is one of numerous cases arising out of the attempted sale in 1853, by the municipal authorities of the City of San Francisco, *318of property known as the City Slips; and depends entirely upon the validity of City Ordinance Ho. 481, which purported to authorize such sale. The charter of the City of San Francisco then in force, declared that no ordinance should be passed “ unless by a majority of all the members elected to such Board.” The Board by law consisted of eight members; but at the time this ordinance was passed, one of the members, Hyde, had resigned, leaving only seven in office, of whdrn four voted for the ordinance and three against it. It is contended that the charter required not less than five affirmative votes to pass an ordinance, and that as this ordinance received only four votes in its favor, it was not therefore legally passed; that it was no ordinance, and no right could be acquired under it. This construction of the charter has been sustained by repeated decisions of this Court. (San Francisco v. Hazen, 5 Cal. 169; Holland v. San Francisco, 7 Id. 361; McCracken v. San Francisco, 16 Id. 594; Grogan v. San Francisco, 18 Id. 590; Pimental v. San Francisco, 21 Id. 351.) The appellant contends, however, that some important questions were overlooked or not considered by the Court in those cases, and therefore asks that the whole subject be reviewed, and a new construction given to the clause of the charter in question; or that it be held inapplicable to the ordinance in question. Where a question involving pecuniary interests of such great value as the present one, has been fully adjudicated for, a long period of time, and is sustained by numerous decisions; and where rights and interests of great value have been acquired under it, it ought not to be disturbed, except for the strongest reasons and under the most urgent necessity. It is with this general view of the subject that we propose to examine the questions raised by the appellants.
It is urged that in those cases it appeared to be an admitted fact that Hyde had been regularly elected a member of the Board, and that a few days before the passage of Ordinance 481, his place became vacant by voluntary resignation. It is claimed that the record in this case shows that he was not thus elected, because he was an alien, and not therefore eligible to the office; that the Board for that year consisted of seven members only, instead of eight, and therefore four constituted a “ majority of all the members elected.” *319It is insisted that this is a new question, presented to the Court for the first time in this case; and that the decision in the cases above referred to are not decisive, even though the language of the opinions is broad enough to cover this question. In the Grogan case, it was stated that the clause of the charter in question was one “ which this Court has held, required for the passage of an ordinance a majority of the votes of the entire number which the charter provided should be elected.” And the opinions in the Hazen and McCracken cases are to the same effect. The proper construction of that clause of the charter was one of the matters to be adjudicated by the Court' in those cases, and we cannot with propriety regard those decisions as mere obiter dicta.
It is not disputed that an election was duly held in the City of San Francisco in September, 1853; that Hyde was one of the candidates at that election; that he received a majority of all the votes cast for Assistant Alderman of the First Ward at such election; that he received a proper certificate of his election; that he took the required oath of office, and was duly installed into the office; that he was declared duly elected by the proper officers, and took his seat with the other members of the board, and acted as such from the time of his election to the date of his resignation, which was a few days before the passage of the ordinance in question. There is no question that the other seven members of the board were duly elected, and that they were eligible to the office. These facts show that there were eight “ members elected,” within the intent and meaning of the charter; and we hold that the number of “ members elected ” was not reduced from eight to seven by the mere fact that Hyde was not eligible to the office by reason of his alienage. The charter provides that each board should “judge of the qualifications of election of its own members.” The board having declared him duly elected, his eligibility was so far determined by the body in which the power was vested by law, as that he became a member of the board, with the right to exercise the same powers and perform the same duties as other members, at least until his right to hold and retain the office had been duly adjudicated in a proper judicial proceeding instituted for that purpose. While he held the office he was an officer de facto, and his acts as such officer were entitled to credit accordingly.
*320It is urged that though there was an election defacto in the First Ward at that time, yet there was no election de jure, because the successful candidate was not eligible. We cannot subscribe to that view. The validity of an election does not depend upon the eligibility of the candidates, for if it did, it might be contended that an election would be invalid because an unsuccessful candidate was disqualified from holding the office voted for. The validity of an election depends upon its being held and conducted at the proper time and place, in the manner and by the proper persons and officers, as required by law. The election in this case was thus held, and it was therefore valid. The person receiving a majority of the votes cast at a valid election may not possess the necessary qualifications to entitle him to take or hold the office to which he is elected; but that is a question to be adjudicated by the proper tribunals.
In this case, the board to which Hyde was elected had the power, to determine this question, and they are to be considered as having decided it wjien they declared him duly elected; but their action was not final. His right to take and hold the office might have been contested under the proceedings authorized by the election law, or by a writ of quo warranto. But the validity of the election, or his right to take and hold the office, cannot be inquired in^o in a collateral action or proceeding like the present. (Turner v. Maloney, 13 Cal. 621; People v. Olds, 3 Id. 174, 175 ; People v. Collins, 7 J. R. 549; Wilcox v. Smith, 5 Wend. 231; Hall v. Luther, 13 Id. 491; Shore v. Scott River Water Company, 17 Cal. 626.)
The case of Searcy v. Grow (15 Cal. 121), referred to by the appellant, does not conflict with this principle, as that was a proceeding under the election law contesting the election of the defendant, and was therefore a proceeding directly against the person claiming the office, to prevent him from taking or holding it. In the case of Turner v. Maloney (13 Cal. 62), it was directly held, that the question of eligibility of an officer could not be tried in a collateral proceeding. In that case it was an application for a mandamus to compel the Controller of State to draw his warrant for the plaintiff’s salary as District Judge. It was opposed, on the *321ground that the plaintiff was ineligible because he held the office of Inspector of Customs, a lucrative office under the United States— a similar question to that-raised in the case of Searcy v. Grow.
But if we are mistaken in our views of this question, we would not feel justified in overturning the previous decisions of this Court construing this clause of the charter. To do so, would clearly violate the rule of stare decisis. Under these circumstances it is not necessary to inquire whether that construction is correct or not.
The judgment is affirmed.
