This is an appeal from a judgment of the superior court of San Luis Obispo County, rendered on a writ of mandamus, commanding the appellant to pay to the respondents certain bonds alleged to have been issued by said county.
The legislature, by an act passed April 4, 1870, which was amended by an act passed March 14,1872, authorized the board of supervisors of the county of San Luis Obispo to issue bonds of said county, “ not exceeding in the aggregate the sum of forty thousand dollars,” for the purpose of erecting a court-house. (Stats. 1869-70, p. 816; Stats. 1871-72, p. 369.) The act provides what interest the bonds should bear, and when they should be payable, and that they should be “ of such denominations respectively as the board shall order.” It is also provided that the clerk of the board should keep a register of the date and number of each bond issued, and the amount realized from the sale thereof, with the name of the purchaser. Two copies of said register were required to be made by the clerk, one to be kept in the office of the county auditor, and the other in the office of the county treasurer. The bonds were to be issued from time to time as the work on the court-house progressed.
The board determined that the bonds should be of the denomination of one hundred dollars, and accordingly four hundred bonds were issued and numbered con*335secutively from 1 to 400, which, of course, amounted to forty thousand dollars, the whole amount allowed by the act. But twenty additional bonds were issued, numbered from 401 to 420, which were over-issues, and entirely unauthorized by the act. These twenty last-named bonds were purchased by respondent for a valuable consideration before maturity, and in the ordinary course of business, and are the subject of this litigation. They were in form negotiable. Interest was paid on them for several years. On the first day of January, 1880, they were outstanding and unpaid.
Subdivision 14 of section 25 of the county government act (Stats. 1883, p. 305) provides that “the board of supervisors of any county having an outstanding indebtedness, on the first day of January, 1880, evidenced by bonds or warrants thereof,” may fund or refund the same, or may pay them with the proceeds of the sale of new bonds issued for that purpose. In supposed accordance with this provision, the board of supervisors of San Luis Obispo County, on May 4, 1885, ordered that the whole of said four hundred and twenty court-house bonds, amounting to forty-two thousand dollars, together with ten thousand dollars of road-repair bonds, be redeemed and paid with the proceeds of the sale of fifty-two thousand dollars’ worth of new bonds. The new bonds were issued and sold, realizing over fifty-two thousand dollars. The appellant (treasurer) paid all of said court-house bonds,-numbered from 1 to 400, but refused to pay the said twenty bonds held by respondents, numbered from 401 to 420. And from the judgment of the superior court commanding him to pay them, the treasurer appeals.
There is a line of judicial decisions in cases where the validity of municipal bonds depended on the happening of some precedent contingency of fact, and the question was, whether the officers executing the bonds were vested with the discretion or power to determine if the contin*336gency had happened. For instance, when municipal officers have" been authorized to issue bonds in aid of railroads, after a proposition to issue them shall have been adopted by the people at an election, the question has frequently arisen whether the officers had power to determine that such election had been properly held, and whether a recital of that fact on the face of the bonds was binding on the municipality. And on such questions the decisions of courts have not been uniform. (The subject will be found fully discussed and authorities cited and quoted in the last few pages of volume 1 of Dillon on Municipal Corporations.) But no such question arises in the case at bar. The validity of the bonds issued under the act of April 4, 1870, did not depend upon any fact—any matter in pais—to be determined by the supervisors. The power to issue the bonds, and the limitation of that power, depend wholly upon the language of the act itself, and not upon any extrinsic contingency. There was' nothing left to the discretion of the officers, as in the case of Porter v. Haight, 45 Cal. 631, nor was there any authority to do what “ might appear to them advantageous to the county,” as in Nevada Bank v. Steinmitz, 64 Cal. 301.
Neither can the doctrine of estoppel, or of ratification, or of bona fide holding, be successfully invoked by respondents. Those doctrines can be invoked against municipal corporations—if at all—only in cases of informality, irregularity, etc., on the part of an authorized agent. (Dillon on Municipal Corporations, 3d ed., secs. 457, 463, 511-553, and cases cited.) “Where there is a total want of authority to issue municipal bonds, there can be no bona fide holding of them.” (Town of East Oakland v. Skinner, 94 U. S. 255.) It is clear—in this state at least—that the issuance of bonds is not within the scope of the general and ordinary powers of a board of supervisors, and that such bonds can be legally issued only by virtue of express authority of the legislature. *337(Dillon on Municipal Corporations, secs. 485, 507, and cases there cited; Lindon v. Case, 46 Cal. 172; Wallace v. Mayor of San Jose, 29 Cal. 181; El Dorado County v. Davidson, 30 Cal. 521; Robinson v. Supervisors of Sacramento, 16 Cal. 208; Foster v. Coleman, 10 Cal. 281; People v. Supervisors of El Dorado County, 11 Cal. 170.) The bonds in question, therefore, were issued without any authority at all, and are wholly void. And the action of' the board of May 4, 1885, ordering these bonds to be redeemed, was, of course, of no value. The character of' one void act of public officers cannot be changed by a. second void act of the same officers, declaring the first act to be valid.
It is quite probable that the respondents paid full par-value for these bonds, and that they will lose their money. But “ those who contract with a municipal corporation are bound to know the extent of the power of its officers.” (Wallace v. Mayor of San Jose, supra.) Respondents would have discovered the worthlessness of the bonds upon the slightest inquiry. At all events, hard eases cannot be allowed to make bad law. An over-issue of" twenty thousand dollars would have been no less valid than the over-issue of two thousand dollars; and any other rule would put the people of a county in the complete power of careless or unscrupulous public officers.
The judgment of the superior court is reversed, with, direction to dismiss the proceeding.
