*202By the Court,
Coleman, J.:This is an application for a writ of prohibition, directed to the respondent, Lena E. Streshley, as county clerk of Lander County, commanding her to refrain from causing to be printed on the official election ballot of said county, to be voted at the ensuing general election, to be held November 7, 1922, the names of O. P. Adams and William L. Watson, or any other name than that of relator, as candidate for the office of long-term commissioner of said county.
The application is based upon the allegation that the board of county commissioners, pursuant to statute (Rev. Laws, 1531), at a meeting duly held on July 2, 1906, divided said county into three commissioner districts, designating them as First district, Second district, and Battle Mountain district, and directed that the long-term commissioner be elected at the election to be held November 6, 1906, from the Battle Mountain district and the short-term commissioner from the Second district; that at subsequent elections for county commissioner in said county a long-term commissioner has been elected from each of said districts alternately; that the long-term commissioner whose term expires at the end of the present year was elected from the Battle Mountain district, and that at the ensuing general election the long-term commissioner should be elected from the First district. It is further alleged that the relator is the only qualified elector of the First district, who has been nominated for long-term commissioner of said county, but that one O. P. Adams, a qualified elector of Battle Mountain district, and William L. Watson, a qualified elector of the Second district, have been nominated for the office of long-term commissioner; also that the respondent, Streshley, is threatening to have printed, and, unless the writ sought issues, will have printed, for the ensuing general election, upon the *203ballot to be voted at said election, the names of said Adams and Watson as candidates for said office of long-term commissioner.
Upon the presentation of the petition an alternative writ was issued, directing respondent Streshley to omit from the ballot to be printed the names of said Adams and Watson, or show cause why they should be printed upon said ballot as candidates for long-term commissioner of Lander County. To the said writ a return has been filed, to which is attached as an exhibit a copy of the petition filed with the board of county commissioners, praying for the dividing of said county into commissioner districts, together with a certified copy of the minutes of the meeting of the board at which the purported action dividing the county into commissioner districts was taken.
It is the contention of relator that the action of the board of county commissioners in making the order dividing the county into commissioner districts is valid, and that no one is eligible to be elected for the long-term except a qualified elector of the First district; also that the return is neither an answer to the petition nor a demurrer thereto, and hence this court must direct the issuance of the peremptory writ as prayed.
We cannot agree with this conclusion. In complying with the show-cause order, we do not think the return of the respondent needs to be a formal pleading in the nature of an answer. If it sets up an admitted or undisputed fact, which defeats the application, it is sufficient. In this instance the return contains, as stated, a certified copy of the proceedings of the board of county commissioners. It contains some other matters, among which is an allegation that the district attorney of Lander County had advised the respondent county clerk that she must cause the names of the respondents Adams and Watson to be printed upon the ballot, but this allegation can in no way affect the sufficiency of the return.
This brings us to a consideration of the question: *204Does the record of the board of county commissioners, as duly certified, show a valid division of the county into commissioner districts? The return shows that at a meeting of the board of county commissioners, held April 3, 1905:
“The petition of citizens asking to have the county divided into commissioner districts was presented to the board and action postponed for further consideration.”
It also appears from the said return that there was a meeting of the board of county commissioners on July 2, 1906, the minutes of which show the following entry:
“On motion of H. R. Lemaire, duly seconded and carried, it was ordered that Lander County be divided into three commissioner districts, to be known as the Battle Mountain commissioner district, the First commissioner district, and Second commissioner district.”
Then follows a description of the territory comprising each district, and a provision that the long-term commissioner to be elected at the ensuing election be elected from the Battle Mountain commissioner district. This is all that appears from the record of the meetings in question. There was no finding that the signers of the petition were qualified electors, or that they constituted 20 per cent of such electors. So far as appears from the record, 50 per cent of the signers of the petition may have been transients.
What we said in the very recent matter of State ex rel. Fall v. Kelso, 46 Nev. 128, 208 Pac. 424, must necessarily control. In that case, following former decisions of this court, we adhered to the well-established rule that a board of county commissioners exercises limited and special powers, and that, when the power of such a board to do a certain thing is questioned, the record must show affirmatively all the facts necessary to give authority to the board to act. The statute in question in the present proceeding requires 20 per cent or more of the qualified electors of a county must petition the board of county commissioners to divide the *205county, to give it power to take such action. In keeping faith the rule recognized in the case mentioned, it must affirmatively appear from the record that the board of county commissioners found as a fact that 20 per cent of the qualified electors of Lander County signed the petition.
Counsel also contends that the respondents should be estopped from urging the defense interposed. The theory advanced in the opening brief to sustain this contention is rather novel. It is said that, since the district attorney in 1905 “presumably” advised the county commissioners that the county could be divided into commissioner districts, and now advises that the action taken is illegal, respondents would seem to be estopped. This is the sole theory, presented to sustain the contention. True, in the reply brief our attention is directed to the case of Coleman v. People, 7 Colo. App. 243, 42 Pac. 1041, and Ashley v. Board of Supervisors, 60 Fed. 55, 8 C. C. A. 455. As to the advice of the district attorney, we may say there is nothing before us to indicate what advice the district attorney gave in 1905; but, assuming that he advised as suggested, it is very evident that the advice given recently was based entirely upon our opinion in the Fall case, supra. In any event, no advice of the district attorney can operate to estop a third party. We may say that neither of the cases mentioned is in point, since the facts in those cases were dissimilar from those in the instant case.
Finally it is said by counsel for petitioner:
“We earnestly submit that the case of State v. McCullough, 3 Nev. 202, at page 222, is absolutely decisive of this case and entitles the relator to the peremptory writ on the pleadings.”
It is not pointed out wherein that case is controlling. We are not favored with counsel’s theory as to its application. It pertained to a private corporation, and no point therein decided applies to the situation here presented, so far as we can see.
Other matters are discussed in the brief, but it. is *206unnecessary to dwell upon them. To prolong this opinion would be a work of supererogation. The writ prayed for should be denied, and the proceeding dismissed.
It is so ordered.
