This is a petition for a writ of mandate, to compel respondent, as secretary of the hoard of directors of Golden Gate Bridge and Highway District, to sign certain bonds proposed to be issued by said district. Respondent justifies his refusal by the claim that the bonds are invalid. A brief review of the history of the district is necessary for an understanding of the questions raised by this proceeding.

In 1923 the legislature enacted a statute, the purpose of which is thus expressed in its title: “An act to provide for the incorporation and management of bridge and highway districts and to provide for the acquisition and construction by said districts of highways, bridges and approaches thereto, and for the acquisition of all property necessary therefor, and also to provide for the issuance and payment of bonds by said districts, for the levying of taxes and the collection of tolls by said districts and for the annexation of additional territory thereto.” (Stats. 1923, chap. 228, p. 452.) The act was amended in 1925 (Stats. 1925, chap. 387, p. 714), in 1927 (Stats. 1927, chap. 344, p. 574), and in 1931 (Stats. 1931, chap. 169, p. 239). Under it, the principal steps in the organization of a bridge and highway district are as follows: The boards of supervisors in the counties in which organization is contemplated determine whether to organize, either by calling elections and securing a popular vote, or by adopting ordinances consenting to such organization, which ordinances are subject to referendum. Thereafter petitions for the formation of the district must be signed by qualified electors of each county and within the boundaries of the district, equal to at least ten per cent of the number who voted in the last election for Governor. These petitions are filed with the Secretary of State, who publishes them for three weeks, together with a notice stating the period in which protests by property owners against inclusion of property within the district will be heard. Such protests are heard by the superior court of the county in which the protesting taxpayer resides, and the court is given power to exclude any lands from the proposed district. Its decision may be reviewed by this court.

In 1925, after the enactment of this statute, an interested group applied to the boards of supervisors of the counties of Del Norte, Humboldt, Mendocino, Lake, Napa, Sonoma, Marin, and the city and county of San Francisco, to pass uniform ordinances as provided in the act. No such action was taken in Humboldt and Lake Counties, but the other six adopted the ordinances. Thereafter petitions were signed by the required number of voters in these counties and notice was published by the Secretary of State. Protests were filed by property owners in all of the included counties except Del Norte. These were heard' in the superior court, and in December, 1928, judgments were entered. These judgments determined that the whole of the counties of Del Norte, Sonoma, Marin, and the city and county of San Francisco would be benefited by the formation of the district. The court excluded a large portion of the county of Mendocino, and a small portion of the county of Napa. The court further determined that the county of Del Norte was properly included in the district notwithstanding the fact that it was not contiguous to the remaining territory, basing this part of its decision on the 1925 amendments to the statute permitting the inclusion of noncontiguous territory. On December 4, 1928, the Secretary of State issued his certificate of incorporation of the district, and notified the boards of supervisors of these counties to appoint members of the board of directors, as required by the act. This was done, and the board then met and commenced its duties, levying and collecting taxes in the district at various times for its expenses. On August 27, 1930, it adopted plans and specifications, engineering and financial, for the construction of a bridge across the Golden Gate between San Francisco and Marin County, which was the object of its organization. By another resolution an election was called to vote upon the proposition of incurring a bonded indebtedness of $35,000,000. After due notice, the election was held on November 4, 1930, in all parts of the district, and the proposition was carried. Subsequently, on June 17, 1931, the board by resolution provided for the issuance of bonds in the principal amount of $35,000,000, and for the sale of $6,000,000 worth, to draw' four and three-fourths per cent interest per annum, payable semi-annually. The said bonds were ordered to be dated July 1, 1931, and to be signed by the president and secretary of the board. Notice of their intended sale was published, and a bid was received and accepted. The board then demanded that respondent sign them. Upon his refusal to do so, this proceeding was commenced.

It should be noted that the legislature in 1931 enacted a validating statute (Stats. 1931, chap. 70) as an urgency measure, which confirmed the incorporation of any such district as of the date of issuance of its certificate of incorporation, and declared valid the boundaries of the district, whether contiguous or noncontiguous. It also ratified the appointment of the members of the board, and all of their proceedings, including those taken for the issuance of bonds.

Prior litigation has determined certain issues involved herein. A writ of mandate was issued by this court compelling the Secretary of State to publish the notice required by the act upon the filing of the petitions. (Doyle v. Jordan, 200 Cal. 170 [ 252 Pac. 577 ].) Upon review in this court at the instance of protesting property owners in the counties of Mendocino, Sonoma, Napa, and the city and county of San Francisco, the judgments of the superior court with respect to the inclusion of land within the district were affirmed. (Wheatley v. Superior Court, 207 Cal. 722 [ 279 Pac. 989 ], and memorandum decisions in Dempster v. Superior Court, 207 Cal. 795 [ 279 Pac. 991 ], Esaisa v. Superior Court, 207 Cal. 796 [ 279 Pac. 992 ], and Crawford v. Superior Court, 207 Cal. 797 [ 279 Pac. 992 ].) An appeal was taken to the United States Supreme Court, and an application was made for a writ of certiorari. The appeal was dismissed and the writ denied. (Crawford v. Superior Court, 281 U. S. 692 [ 74 L. Ed. 1121 , 50 Sup. Ct. Rep. 238].) As a result of these decisions, it is now seU tied that the proceedings taken in the formation of the district sufficiently complied with the Constitution and statutes-of this state, and that such proceedings did not conflict with any right under the federal Constitution.

The present proceeding involves only the validity of the proposed bonds and the power of the district to levy taxes in payment of the interest and principal thereof. These matters were expressly reserved in the prior decisions above mentioned. The attack upon the bonds made by respondent and by amici curiae rests upon a number of grounds, which may be briefly noted under the following heads: (1) The power of an appointive board to tax; (2) the alleged lack of provision for equalization of property values; (3) the insufficiency of the petitions of the electors in the city and county of San Francisco; (4) inequalities arising from the boundaries of the district; (5) the applicability of the statutory changes in 1931. Before considering any of these points, however, it is necessary to decide whether this proceeding is one of which this court may take jurisdiction, for the purpose of determining them. It is contended by amici curiae, representing certain taxpayers not parties herein, that the proceeding is fundamentally collusive in its nature by reason of the fact that there is in reality no controversy between petitioner and respondent. These amici curiae have filed and argued a motion to dismiss the petition. It is to this motion that we first address ourselves.

Preliminarily it may be observed that to grant this motion would be to prevent a speedy determination of the validity of the proposed bonds, and hence to delay the commencement of the project, perhaps for years. Such a result should be avoided if it is reasonably possible to do so. The value of the proposed bridge is statewide; when constructed, it will become an integral part of the Redwood Highway, linking the northern and southern parts of the .state with one continuous modern avenue for traffic, and also a part of the state highway entering two neighboring states. The board of directors has completed its plans, has already entered into exceptionally favorable contracts for construction, and has solicited bids for its bonds. All such bids, however, have been conditioned upon a judicial determination of their validity. The legislature itself has, in enacting the 1931 amendments to the statute and the validating act, declared the urgency of prompt action, both to relieve congested traffic and to furnish work for a large number of people now unemployed. This court cannot lightly thrust aside a proceeding so important to the welfare of the citizens of the state. In our opinion, a controversy is presented of which we have jurisdiction.

It is conceded that respondent secretary is personally desirous of a decision'in favor of petitioner. In other words, this is a friendly suit. It appears that the bridge district agreed to reimburse respondent for the expense incurred by him in the litigation, in the event that the contractors or the bidders for the bonds or other persons interested did not do so. It likewise appears, however, that the bidders” for the bonds have agreed with respondent to secure payment of the expenses of the litigation incurred by him and that there is no agreement with such bidders and the district for reimbursement from the district for such expenses. These facts, amici curiae assert, show that the proceeding is fictitious and collusive, being a mere attempt to secure an advisory opinion without an actual contest. They further contend that the validity of the bonds is not even an issue in the case, for the reason that respondent, an employee of the board, is bound to sign them regardless of his opinions, and that he may be discharged for his refusal to do so. The real controversy, they claim, is between the district and taxpayers who are not parties to the suit.

Neither on principle nor authority does this position commend itself to us. It is, of course, the prevailing doctrine in our judicial system that an action not founded upon an actual controversy between the parties to it, and brought for the purpose of securing a determination of a point of law, is collusive and will not be entertained; and the same is true of a suit the sole object of which is to settle rights of third persons who are not parties. (Haley v. Eureka County Bank, 21 Nev. 127 [12 L. R. A. 815, 26 Pac. 64 ].) That is not the situation here. Respondent, though an employee of the board and serving at its pleasure, is a public official, holding office pursuant to the provision made by the statute, and bound by oath to support the Constitution and laws of this state. His signature on the bonds is required by the statute. The bonds which he refused to sign recite that “provision has been made by law for the levy and collection of a direct annual tax upon all taxable property within said district sufficient to pay the

principal and interest o£ this bond”. He contends that the legislative provisions giving such power to tax are unconstitutional, and that the recital is therefore incorrect. This same opinion has been expressed by many persons, including lawyers of repute. It was also raised in the prior litigation involving this district, and was by this court expressly left undecided. (Doyle v. Jordan, supra; Wheatley v. Superior Court, supra.) If respondent’s contention is sound, and he were forced to sign, he would be acting in violation of his public duty, and assisting in the deception of prospective purchasers of the bonds. He is not bound to take a step which might conceivably involve a personal liability on his part in the event of a subsequent judicial declaration of unconstitutionality of the act, or falsity of the recitals in the bonds. (Brandenstein v. Hoke, 101 Cal. 131 [ 35 Pac. 562 ]; Denman v. Broderick, 111 Cal. 96 [ 43 Pac. 516 ]; Hopkins v. Clemson Agr. College, 211 U. S. 636 [35 L. R. A. (N. S.) 243, 55 L. Ed. 890 , 31 Sup. Ct. Rep, 654]; see discussion in Field, Unconstitutional Statutes and Public Officers, 77 Univ. Pa. L. Rev. 155; Raspacz, Officers Acting Under Void Statutes, 11 Minn. L. Rev. 585 ; Crocker, Liability of Public Officers, 2 So. Cal. L. Rev. 236.) Though a ministerial officer, he may nevertheless refuse to sign an instrument believed by him to be invalid. (City of North Sacramento v. Irwin, 94 Cal. App. 652 [ 271 Pac. 788 , 272 Pac. 767 ]; State v. Dolley, 82 Kan. 533 [ 108 Pac. 846 ].) Nor is the fact that he is removable at the pleasure of the board material, for his successor would be in exactly the same position. A genuine controversy existed, therefore, between petitioner and respondent as to matters vitally affecting the duties and perhaps the liabilities of the latter. Able counsel were retained to present the case for respondent to this court, and it is not suggested that they were lacking in diligence or good faith in their preparation of the case. Under these circumstances this court can properly consider the petition and adjudicate the issues raised therein. We said in Price v. Sixth District Agr. Assn., 201 Cal. 502, 516 [ 258 Pac. 387, 393 ]: “It may well have been that the mayor of the City and the chairman of the board of supervisors would have liked to see this public improvement carried out; nevertheless, it is a fact found by the court and warranted by the evidence that these officers doubted the validity of the contract and the power of the City and County to enter into it. It is also true that reputable counsel of high standing representing the interested parties denied the validity of the contract and the power of the City and County to enter into it and the interests financing the construction of the improvement refused to proceed until validity had been determined. The litigation was thereupon fought in good faith with fairness and earnestness . . . and upon such a showing the conclusion must be that the court’s implied finding that collusion was absent is supported.” In Floersheim v. Board of Commrs., 28 N. M. 330 [ 212 Pac. 451, 453 ], referred to in the foregoing decision, the court pointed out that there is nothing improper in a friendly suit by a party who, though attacking the validity of bonds, is hopeful that they will be upheld: “The personal desires of the parties as to the result of the litigation are of no moment, provided no fraud or collusion is resorted to.” (See, also, State v. Dolley, 82 Kan. 533 [ 108 Pac. 846 ]; W. E. Bowen Imp. Co. v. Van Hafften, 209 Mo. App. 629 [ 238 S. W. 147 ]; Parker v. State, 132 Ind. 419 [ 31 N. E. 1114 ]; Ex parte Steele, 162 Fed. 594 ; Cone v. Gilmore, 79 Or. 349 [ 155 Pac. 192 ]; McCoy v. Carren, 179 Ky. 590 [ 201 S. W. 463 ].)

This court has over a long period of years taken jurisdiction in many proceedings substantially similar to the instant case; that is to say, it has, on petition for writ of mandate, determined the validity of the bonds or contracts of a public corporation. A few of the more recent cases are Los Angeles County Flood Control Dist. v. Wright, 213 Cal. 335 [ 2 Pac. (2d) 168 ]; California Toll Bridge Authority v. Wentworth, 212 Cal. 298 [ 298 Pac. 485 ]; City of Pasadena v. Chamberlain, 204 Cal. 653 [ 269 Pac. 630 ]; Slavich v. Hamilton, 201 Cal. 299 [ 257 Pac. 60 ]; City of Long Beach v. Lisenby, 175 Cal. 575 [ 166 Pac. 333 ]; La Mesa etc. Irr. Dist. v. Halley, 197 Cal. 50 [ 239 Pac. 719 ]; Montecito County etc. Dist. v. Doulton, 193 Cal. 398 [ 224 Pac. 747 ]; Los Angeles County etc. Dist. v. Hamilton, 177 Cal. 119 [ 169 Pac. 1028 ], Several earlier decisions have been cited by amici curiae which might appear, to some extent, in conflict with this array of authority. In City of Los Angeles v. Lelande, 157 Cal. 30 [ 106 Pac. 218 ], mandate was sought to require the city clerk to certify that an ordinance was duly passed, and he based his refusal on the claim that it was illegal. The court, in a brief opinion, denied the petition. In County of Orange v. Backs, 77 Cal. App. 744 [ 247 Pac. 519 ], a similar case, involving the duty of a county clerk to attest an ordinance calling an election to determine whether bonds should be issued, he refused on the ground of the illegality of the bonds if they should be voted. In Marin Municipal Water Dist. v. Dolge, 172 Cal. 725 [ 158 Pac. 187 ], the proceeding was to compel the auditor of the district to countersign certain bonds, and the court said that there was no statutory necessity that he do so, the requirement being established by the mere direction of its board of directors. It is contended by petitioner that there are important differences between the instant case and those just discussed, in that the signature of respondent is a statutory requirement, and such signature attests not the due passage of an ordinance, but the obligation of the bond itself. Irrespective of such differences, however, the cases are contrary to the uniform course of decision pursued by this court in granting writs of mandamus, and any language in them which might suggest that it is always the duty of a ministerial officer to act according to the direction of his superiors irrespective of his own views as to the validity of such action, must be considered dictum, and disapproved by later decisions.

Amici curiae were invited by petitioner and by this court to bring their clients into this proceeding by intervention, a procedure which has been heretofore permitted by this court (Wright v. Jordan, 192 Cal. 704 [ 221 Pac. 915 ]), provided that the issues raised were relevant. (La Mesa etc. Irr. Dist. v. Halley, 195 Cal. 739 [ 235 Pac. 999 ].) Opportunity was also offered them, whether they intervened or not, to present to the court as fully as they might deem desirable, their objections to the proposed bond issue. Their refusal to intervene was chiefly based upon what we consider to be a wholly untenable ground, namely, that it might jeopardize their right of appeal to the United States Supreme Court. We need not enter into a discussion of this or the other grounds for such refusal, since the only bearing it has on the motion to dismiss is in relation to the claim of collusive action between petitioner and respondent. It surely cannot be said that this proceeding was brought to reach a collusive determination of the rights of such third parties, when they were urged to come into court and present their own views of the case.

We are satisfied that this court may properly determine the issues hereinbefore mentioned, and that our determination will have the usual force and effect of a final judgment on those issues. (Price v. Sixth Dist. Agr. Assn., supra.) The motion to dismiss is therefore denied, and we come now to a consideration of the merits of the controversy.

The first objection made by respondent is that the Bridge and Highway District Act violates article XI, section 12, of the California Constitution, in providing for the appointment of the board of directors of petitioner by the boards of supervisors of the counties. The said section is as follows: “The legislature shall have no power to impose taxes upon counties, cities, towns or other public or municipal corporations, or upon the inhabitants or property thereof, for county, city, town, or other municipal purposes, but may, by general law, vest in the corporate authorities thereof the power to assess and collect taxes for such purposes.” Respondent contends that to come within the meaning of “corporate authorities”, such board must be elected by the electors of the district. Preliminarily, it may be noted that this contention is grounded mainly upon the notion of an “inherent right” of local self-government, which is contrary to the great weight of authority, and cannot be said to have been adopted in this state. (See Johnson v. San Diego, 109 Cal. 468 [30 L. R. A. 178, 42 Pac. 249 ]; Booten v. Pinson, 77 W. Va. 412 [L. R. A. 1917A, 1244, 89 S. E. 985 ]; Lillard v. Melton, 103 S. C. 10 [ 87 S. E. 421 ]; Trenton v. New Jersey, 262 U. S. 182 [29 A. L. R. 1471, 67 L. Ed. 937 , 43 Sup. Ct. Rep. 534]; State v. Williams, 68 Conn. 131 [48 L. R. A. 465, 35 Atl. 24, 421 ]; 6 R. C. L. 23; 12 C. J. 754; 1 Dillon, Municipal Corporations, 5th ed., 154; McBain, Right of Local Self-Government, 16 Columb. L. Rev. 190, 299.) Furthermore, such a contention takes no account of the manifest assent of the voters expressed in their passage of the ordinances and their favorable vote at the bond election. But considering the language of the Constitution, we think the suggested interpretation is unsound, and is, in fact, inconsistent with other provisions. Thus, article XI, section 5, provides for the election or appointment of county, township and municipal officers; and article XX, section 4, declares generally that all officers whose election or appointment is not provided for elsewhere in the Constitution, and all officers whose offices or duties may hereafter be created by law, “shall be elected by the people, or appointed, as the legislature may direct”. For a discussion of the interpretation of similar constitutional provisions, see Milheim v. Moffatt Tunnel Imp. Dist., 72 Colo. 268 [ 211 Pac. 649 ]; State v. Edwards, 38 Mont. 250 [ 99 Pac. 940 ]; State v, Cooney, 70 Mont. 355 [ 225 Pac. 1007 ].

Irrespective of this interpretation of “corporate authorities”, the objection must fall by reason of the prior decisions of this court to the effect that the section is limited to taxes for local “municipal purposes” and has no application to the taxing power of a district organized for a state purpose. That the development of the highway system of the state is a state purpose is obvious, and it has been so declared. (Matter of Schuler, 167 Cal. 282 [Ann. Cas. 1915C, 706, 139 Pac. 685 ].) In Wheatley v. Superior Court, supra, at page 726, we pointed out that the petitioner was a quasi-municipal corporation, substantially similar to “a municipal water district, a public utility district, a municipal utility district and a metropolitan water district”. The effect of this holding as to its nature, coupled with the fact that it has a state purpose, is to take it out of the above-mentioned constitutional limitation, and to bring it within the rule that the legislature has the power to provide for taxation by appointive boards in such districts. (Stu ckenbruck v. Board of Supervisors, 193 Cal. 506 [ 225 Pac. 857 ]; City of Pasadena v. Chamberlain, 204 Cal. 653 [ 269 Pac. 630 ]; Henshaw v. Foster, 176 Cal. 507 [ 169 Pac. 82 ]; Pixley v. Saunders, 168 Cal. 152 [ 141 Pac. 815 ].)

The- second objection of respondent is that the act is unconstitutional in failing to make definite provision for equalization of property values and the ascertainment of tax rates. The argument is that under the statute the tax rate must be fixed in July; that the county boards of supervisors sit as boards of equalization in July, and the state board of equalization sits in August; and that therefore the rate must be fixed prior to the determination of the property values. Although it has been declared that there is no constitutional necessity that equalization precede the fixing of the tax rate (People v. Latham, 52 Cal. 598 ), section 14 of the act does not require the construction given it by respondent. It reads, in part, as follows: “The Board of Directors shall in the month of July of each year determine the amount necessary to be raised by taxation, and shall fix a rate of taxes to be levied which. will raise the amount of money required by the district. ...” This section clearly requires that the estimate of necessary funds be made in July, but it specifies no particular time for the fixing of the tax rate. The board may do so at any time so long as it certifies the rate to the boards of supervisors of the respective counties “within a reasonable time previous to the time when boards of supervisors are required by law to fix their tax rates”. The further suggestion that no adequate provision for equalization exists is equally untenable. Section 14 requires the board to certify the rates to the boards of supervisors of each county “with a direction that at the time and in the manner required by law for the levying of taxes for county purposes such board of supervisors shall levy and collect a tax. ...” It is plain that this method involves the usual process of valuation by county boards of supervisors and by the state board of equalization. (California Constitution, art. XIII, sec. 9; Pol. Code, sec. 3692.) It must be presumed that such boards will properly perform the duties imposed upon them by the Constitution and the general law.

Another contention made by respondent and also by amici curiae is that the city and county of San Francisco was never properly made a part of the district. By some curious mischance, only 13,094 signatures of electors were obtained on the petition, and the total number of votes cast for Governor in the general election was 132,225. These facts appeared on the face of the petition. Nevertheless, this irregularity can no longer be urged. The previous litigation involving the district had as its object the determination of the validity of its formation and the inclusion of territory within its boundaries. The decisions in Doyle v. Jordan and Wheatley v. Superior Court, supra, are conclusive on all points which were raised or could have been raised therein. (Price v. Sixth Dist. Agr. Assn., 201 Cal. 502 [ 258 Pac. 387 ]; Floersheim v. Board of Commrs., 28 N. M. 330 [ 212 Pac. 451 ]; Davis v. Willis, 19 N. D. 209 [ 124 N. W. 706 ].) The passage of the validating act, moreover, removes all possible doubt as to this result. Section 1 of that act expressly confirms the organization of the district. (Stats. 1931, chap. 70, p. 77.) The defect under consideration was a failure to comply with the terms of the prior statute; there was no violation of the Constitution. In such case, the legislature has power, by the enactment of a curative statute, to declare that the nonobservance of any of the requirements of the former act shall not be subject to further inquiry. (Marr v. Southern Cal. Gas Co., 198 Cal. 278 [ 245 Pac. 178 ]; Watkinson v. Vaughn, 182 Cal. 55 [ 186 Pac. 753 ]; Los Angeles County Flood Control Dist. v. Hamilton, 177 Cal. 119 [ 169 Pac. 1028 ]; Imperial Land Co. v. Imperial Irr. Dist., 173 Cal. 660 [ 161 Pac. 113]; Wood v. County of Calaveras, 164 Cal. 398 [ 129 Pac. 283 ]; Chase v. Trout, 146 Cal. 350 [ 80 Pac. 81 ].) The assertion that this validating act is special legislation is without foundation. It is general in its terms, and though it applies only to this one district which has already been organized, it is nevertheless the rule that the constitutional inhibition does not apply. (San Pedro etc. R. R. Co. v. Hamilton, 161 Cal. 610 [37 L. R. A. (N. S.) 686, 119 Pac 1073 ].)

Another objection of respondent and amici curiae which is urged with some force is that the boundaries of the district are fixed so arbitrarily as to constitute a denial of equal protection of the laws. The particular ground for this contention is the inclusion of Del Norte County, noncontiguous with the rest of the district, and separated from the remainder by Humboldt County, which did not come in. The provision for the inclusion of noncontiguous territory was, as hereinbefore mentioned, part of the amendments of 1925. The possibility of one county which receives benefit from the project refusing to pass the ordinance was in the contemplation of the organizers of the district and wa,s known to all of the boards of supervisors when they passed the ordinances; and the present boundaries of the district, embracing noncontiguous territory, were likewise known to the electors when they voted in favor of the bond issue. In addition, taxpayers had the right to seek a referendum upon the passage of any ordinance, and the right to protest to the superior court against the inclusion of any of their lands. Finally, in the prior cases before this court, they had the opportunity to raise this point, and, in fact, it was raised and thoroughly argued. The decisions of this court in Doyle v. Jordan and Wheatley v. Superior Court, supra, are conclusive on the validity of the organization of the district. In short, the point urged now by respondent, and by amici curae on behalf of certain taxpayers not parties herein, could have been presented in the regular manner provided by the act and within the three months’ period specified therein from the date of issuance of the certificate of incorporation (see Miller & Lux v. Secara, 193 Cal. 755 [ 227 Pac. 171 ]), and was actually presented by other taxpayers and decided adversely to their claims. The decisions are final, and the matter is res judicata at this time. (Price V. Sixth Dist. Agr. Assn., supra; Farncomb v. City and, County of Denver, 252 U. S. 7 [ 64 L. Ed. 424 , 40 Sup. Ct. Rep. 271].)

It is argued, however, that the refusal of this court in the Doyle and Wheatley cases to determine the power to tax leaves open the question of the validity of the boundaries, in so far as the taxing power is concerned. In order to lay at rest any doubt as to this point, therefore, we now hold expressly that the power of taxation given to the district with its present boundaries does not violate the constitutional guaranty of equal protection. It is not an assessment district, where the tax must be levied in accordance with benefits actually received by the individual taxpayer. It is, as we declared in the Wheatley case and as hereinbefore repeated in this opinion, a quasi- municipal corporation. As such, its tax “is not a tax or assessment on property directly benefited by the construction of some local improvement, but is a general tax levied just as, and for the same purpose that any general municipal tax is imposed for carrying on the governmental functions and utilitarian objects of duly incorporated cities or towns”. (In re Orosi Public Utility Dist., 196 Cal. 43, 58 [ 235 Pac. 1004, 1010 ].) The inclusion of noncontiguous land in such a district is not a ground for constitutional attack. Nor is it a valid objection that other land which receives equal benefit is not included or for some other reason is not subject to tax. As the court said in Randolph v. County of Stanislaus, 44 Cal. App. 322, 330 [ 186 Pac. 625, 628 ], “It is a matter of common knowledge that in the state of California municipal corporations are not often contiguous, but are separated by intervening territory, and if the formation of districts composed of two or more municipal corporations is to be confined to municipal corporations that arc adjacent to each other, then very few public utility districts composed entirely of municipal corporations can be formed in the state of California.” (See, also, People v. Town of Loyalton, 147 Cal. 774 [ 82 Pac. 620 ].)

There remains finally the problem of the amendments to the statute enacted in 1931, by which changes were made in sections 14 and 21. It is most vigorously contended by respondent, and by amici curiae that these amendments, enacted after the bond election, make such a substantial change in the conditions of the authorization of the bond's as to invalidate them if they are issued under the act as amended. The argument, directed mainly at the changes in section 21, is to the effect that the original act provided for the issuance of certain bonds upon a vote of the electors; that prior to completion of the project the principal and interest of such bonds were payable only from proceeds of the sale of the bonds; and that no tax could be levied unless and until the bridge was completed. In its present form section 21 plainly authorizes a tax prior to such completion, and in effect it places the taxing power of the district behind the bonds by permitting either principal or interest to be raised by taxation where necessary. Hence, if the interpretation of the original act urged by respondent and amici curiae is correct, a basic change was made.

Petitioner’s answer is twofold. First, it is stated that the original act, though somewhat uncertain in its details, conferred the general power of taxation for its bonds upon the district and that the amendments of 1931 clarified its provisions and were merely procedural in character. After a careful study of the original act, we have reached the same conclusion. Section 21, prior to 1931, read in part as follows:

The statutory direction is clear up to a certain point: Until the bridge is built and revenues are received, interest on the bonds is to be paid out of the proceeds of the sale of the bonds. The language used contains the assumption that until the bridge is built and money is earned, there will be sufficient funds derived from the sale of the bonds to meet the interest payments. But as to the procedure in the event of a lack of such funds, section 21 is silent. And that is all that can be said in support of the position of respondent and amici curiae. Section 21 was drafted with no express provision for that particular contingency. It does not state that interest shall be payable only, solely, or exclusively out of the designated fund; nor does it say that it shall not be paid at all until the bridge is in operation. The indication of a preferential fund from, which interest is to be paid cannot be deemed to imply a repudiation of the obligation to pay interest save in the manner indicated. (Avery v. Job, 25 Or. 512 [ 36 Pac. 293 ]; United States v. Fort Scott, 99 U. S. 152 [ 25 L. Ed. 348 ]; United States v. County Court, 96 U. S. 211 [ 24 L. Ed. 628 ]; Norris v. Montezuma Valley Irr. Dist., 248 Fed. 369 .)

Considering the situation as to the principal of the bonds, the objection is even less impressive. The clause which reads “except that until the operation of the works of the district has commenced” applies only to interest. The preceding provision, covering “principal or interest”, permits the levy of taxes if the revenues of the district are, “or in the judgment of the board of directors, will probably be inadequate”. The power to tax for the principal of the bonds is directly given by this section, without any qualification at all; and the same is true of the power to tax for the interest, unless the power as to interest is destroyed by the subsequent clause. It would be most unreasonable for the legislature to provide that the district could, by taxes, meet the binding obligation of the principal of the bonds, and could never by such method meet the equally binding obligation of the interest. The unreasonableness of such an interpretation is further apparent if the first and second parts of the section are compared. The first part declares the right to tax for principal or interest. Can it be assumed that the legislature in one sentence intended both to give and to take away that power? Such a result cannot be conceded unless the language leaves no alternative. In fact, it does leave an alternative which is both obvious and reasonable. The qualifying clause as to interest does not destroy the power to tax, given by the preceding language; it merely restricts that power. It prevents any tax for interest in pursuance of the previously granted power to levy such tax as long as there are funds available from the proceeds of the sale of the bonds. We are convinced that this was the legislative intention and that it is reasonably deducible from the language of the section. We are aware of the doctrine of “strict construction” of tax statutes, but to say that such a statute must be strictly constructed does not mean that it is to be given an unnatural construction to defeat the tax. It should be construed reasonably. (Riley v. Havens, 193 Cal. 432 [ 225 Pac. 275 ]; Estate of Parrott, 199 Cal. 107 [ 248 Pac. 248 ]; see 2 Cooley on Taxation, 4th ed., 1123.)

We have thus far confined ourselves to section 21, but an examination of other parts of the original act fully confirms our conclusion. Considered as a whole, the act made the bonds a binding obligation of the district. Section 8 gives such a district the power “to borrow money, incur indebtedness and to issue bonds or other evidence of such indebtedness”. Section 15 provides for the calling of an election when it is deemed necessary to incur a “bonded indebtedness”. Section 17 provides that any bonds issued by it are “legal investments for savings banks”, and they are given “the same force and value and use as bonds issued by any municipality. If the district is not obligated to pay either principal or interest save from revenues, its bonds cannot be an “indebtedness” of the district; and it would be in the highest degree absurd to make them legal investments for savings banks unless the district stood behind them. But if they have the force, value and use of municipal bonds, they are, like municipal bonds, general obligations in payment of which taxes can be levied. Finally, section 10 specifically provides that such a district shall have power “to cause taxes to be levied for the purpose of paying running expenses, the organization expenses and the investigation expenses of the district before the issuance of bonds, and after the issuance of bonds to cause taxes to be levied for the purpose of paying any obligation of the district. . . . ” This language is certainly broad enough to authorize taxes to pay the obligation of the district incurred through the issuance of bonds.

Upon the theory that the act at least was ambiguous in its provisions prior to 1931, amici curiae advance the further contention that the ambiguity was resolved by the district against the taxing power by reason of the publication of a 110-page report of the chief engineer on the general plan of the project, which contained the brief declaration that “taxes may be levied only for preliminary expenses”, “or to cover deficiencies of revenue after construction has been completed”. It seems too plain for argument that this statement, part of a lengthy report on other subjects, cannot be deemed to be an official interpretation by the district of the legal effect of the act. In any event, it has no efficacy when in conflict with the law itself. The proposition as it appeared on the ballot was more accurately expressed. It specified' that “interest shall be paid” out of proceeds, and did not use the word “only”. It also stated that the proposition was to “incur a bonded indebtedness”. Although this point goes only to the good faith of the district and not to the validity of the bonds, still it may not be amiss to express our view that the voters were not deceived by the report, the ballot or the original act. They believed that proceeds from the sale of bonds and revenues from the operation of the bridge would be resorted to for the payment of interest and principal before any tax would be levied, and in this belief .they were of course correct. They were, however, presumed to be familiar with the statute (Los Angeles County Flood Control Dist. v. Wright, 213 Cal. 335 [ 2 Pac. (2d) 168 ]; Inglewood v. County of Los Angeles, 207 Cal. 697 [ 280 Pac. 360 ]), and they certainly knew that a costly project was to be built and financed by bonds selling at par with a low rate of interest. All of these factors tend to indicate full knowledge on their part that the bonds were to be general obligations of the district, supported by the power of taxation.

The other changes made by the 1931 amendments require only brief mention. Section 14 was amended to provide that running expense of the district during the period of construction was to be deemed part of the cost of construction and could be paid out of proceeds of the sale of the bonds. This places no extra burden on taxpayers since it contemplates no tax; and, as a matter of fact, the expenses of the district during that period may reasonably be said to be part of the cost of construction, since the district has no other .purpose than the construction of the bridge. Section 21 provides for the creation of certain funds for reserve interest, operating expenses, repairs and depreciation, and a sinking fund. If the board may validly collect money for its statutory purposes, it may segregate the funds so collected for these purposes, and doubtless would have had such power without express statutory provision. Section 21 further authorizes the board to borrow money in anticipation of taxes, to meet deficits in payment of principal or interest of bonds. The original act gave express power to borrow money for all proper purposes of the district. (Sec. 10, subd. 8.) Another amendment to section 21 changes the method of distribution of surplus revenues, by deducting certain sums for previous deficits, operating expenses for the next six months and reserve interest, before dividing it among the counties of the district. Plainly, the use of such surplus partially to reduce the ultimate obligation of the district cannot injure taxpayers. Finally, section 21 as amended permits interest to be paid out of proceeds of the sale of bonds until six months after the board’s estimate of the period of completion of the work, instead of until completion, as previously specified. The purpose of this is to guard against default in the payment of interest by reason of inability of the district to secure the necessary funds im mediately upon completion, either by revenues or taxes. No injury to taxpayers can result from this provision.

Our conclusion, already stated, is that the amendments of 1931 were of a procedural character, and made no substantial change in the obligations of the taxpayers. It is therefore unnecessary to consider the contention of petitioner that even substantial changes might be validly made by the legislature after a bond election, where, as here, there is no constitutional requirement of an election. Nor is it necessary to dwell upon the contention that as a matter of construction the amendments should not be applied retroactively to the bonds authorized at the election of November 4, 1930. The legislative intention is unmistakable; the amending act is declared to be an urgency measure, and was obviously designed to facilitate the issuance of bonds by petitioner, the only district as yet organized under the statute. The further contention of amici curiae that such a retroactive interpretation would result in a lack of uniformity under article I, section 11, of the California Constitution, is .equally untenable. The statute as amended applies uniformly to all bridge and highway districts and to all bonds to be issued by them.

There being no merit in any of the objections to the issuance of the proposed bonds, it is the duty of respondent to sign them as directed by petitioner. It is therefore ordered that the writ of mandate issue.
