The order appealed from was granted upon the complaint, answer, affidavits, and certain proceedings of the common council of the defendant city. The material facts are substantially undisputed. It was established upon the hearing of the motion for injunction that the action was brought by the plaintiff on behalf of himself and all other taxpayers similarly situated; that the defendant city submitted a proposition to the voters whether $500,000 of municipal electric light bonds should be issued, which was car*507ried, and between January 1, 1902, and January 1, 1908, the city did issue $150,000 bonds and sold the same and received therefor $150,000 and purchased a piece of real estate in the city of Milwaukee for a site for said municipal electric light plant and paid $60,000 therefor; that the bonds were thereafter declared void by this court, and in May, 1911, the legislature of this state passed an act known as ch. 75, Laws of 1911, entitled “An act to create section 927 — 19®, to legalize bonds issued and sold by any city for the construction or purchase or erection and maintenance of an electric lighting plant, and to legalize the expenditure of the proceeds of such bonds;” that between July and August, 1911, the defendant city took proceedings for the installing of machinery in connection with a refuse incinerator in operation in defendant city and expended some $60,000 of the electric light bonds fund for such purpose, which said plant was to be an auxiliary plant and a unit of the city’s main electric plant, the purpose of such auxiliary plant being to use the waste steam at the incinerator plant; that the defendant city has not obtained from the Wisconsin railroad commission, under ch. 499 of the Laws of 1907, any certificate of convenience and necessity; that there are several public utilities operating in the defendant city, and, among others, the Milwaukee Electric Railway & Light Company, which last named company had had a contract with the defendant city for the purchase of electric light in connection with municipal needs of defendant city, and that said the Milwaukee Electric Railway & Light Company owns an indeterminate permit under the laws of this state; that between September, 1910, and March, 1912, the defendant city issued $100,000 of municipal electric light bonds and was about to sell the same before this action was commenced and use the proceeds for the construction of a plant for furnishing electric light for lighting the streets, public grounds, and public buildings of the defendant city and for furnishing power for municipal pur*508poses in said defendant city; that prior to the 11th day of July, 1907, the defendant city spent, in addition to the $60,000 for a site in connection with the construction of the electric light plant in question, large sums of money, and prior to the passage of ch. 596, Laws of 1911, spent other large sums of money, aggregating upwards of $12,000.
There are some general allegations in the complaint denying the regularity of the proceedings of the common council of the defendant city, and also the validity of the last issue of bonds, and some charges respecting the unlawful diversion of funds. . These allegations are positively denied in the answer. But the facts which go to the merits of the controversy here are undisputed, or substantially so.
On the part of the appellants it is insisted that the present action cannot be maintained by the plaintiff as a taxpayer; that the acts of the city which have been enjoined are lawful, and that as to the auxiliary plant the action cannot be maintained because of laches. The respondent seeks to sustain the order below on the following grounds: First, that the 1912 issue of bonds was illegal; second, that the construction of the auxiliary plant by diverting the proceeds of the 1906 issue of bonds for that purpose was unauthorized; third, that the city has no right to use the streets for stringing or laying its electric wires and cables; and fourth, that the defendant city cannot construct an electric light and power plant until it has obtained a certificate of convenience and necessity from the railroad commission. The last ground seems to be mainly relied upon for affirmance.
It is contended by counsel for appellants that the plaintiff as a taxpayer of the defendant city cannot maintain this action. But we think the question is not new in this state, and must be regarded settled against the contention of appellants. Neacy v. Milwaukee, 142 Wis. 590, 126 N. W. 8; Kyes v. St. Croix Co. 108 Wis. 136, 83 N. W. 637; Linden L. Co. v. Milwaukee E. R. & L. Co. 107 Wis. 493, 83 N. W. 851; Rice *509v. Milwaukee, 100 Wis. 516, 76 N. W. 341; Oconto City W. S. Co. v. Oconto, 105 Wis. 76, 80 N. W. 1113; Weik v. Wausau, 143 Wis. 645, 128 N. W. 429; Herman v. Oconto, 110 Wis. 660, 86 N. W. 681.
The 1906 issue of bonds was legalized by ch. Y5, Laws of 1911, so there is no question made upon these bonds, and the auxiliary plant was constructed out of that issue, and the validity of the 1912 issue in no way affects the right of the city to construct the auxiliary plant. The attempt of the respondent to show that the 1912 issue is invalid is feeble. The allegations are general and there is no particular specification of grounds of invalidity. Besides, such allegations are on information and belief, and are positively denied in the answer. The facts showing invalidity presumably are such as to be capable of specification and positive allegation, and the rule of pleading pertaining thereto ought to be observed. Steinberg v. Saltzman, 130 Wis. 419, 110 N. W. 198. We have carefully examined the record and find no ground for holding that the 1912 bonds are illegal.
The alleged diversion of the so-called 1906 bonds is claimed to be illegal. These bonds are denominated “Municipal electric light bonds.” One hundred and fifty thousand dollars of these bonds were issued in pursuance of a vote of the electors upon the following proposition, namely, “Shall $500,000 municipal electric light bonds be issued to erect and maintain a municipal electric light plant?” Eorty thousand dollars of this issue was by resolution of the common council appropriated for installing certain machinery at the refuse incinerator plant for the purpose of utilizing surplus steam which otherwise would be wasted. A careful examination of the record does not show that there was any substantial diversion of the funds, even if it be admitted that a municipal electric light plant does not include a power plant, incidental or otherwise. The plant to which the said $40,000 claimed to be diverted was applied is known as the auxiliary plant, *510and is, under the proceedings of the common council, a unit of the electric lig’ht plant and to be used, in part at least, for the generation and distribution and use for the city of electric light. And in this behalf it may be observed that the answer alleges that it is the intention to use the power generated at the auxiliary plant for lighting streets, public buildings and grounds, and to use for power purposes only so much thereof as shall not be necessary for lighting, and “to charge the sewerage fund of said city with the value of the power furnished for the operation of flushing station, and to credit the lighting fund with said amount.” It seems clear from the record that the purpose of the city is to use the proceeds of the 1906 bonds primarily for lighting purposes, and therefore there is no diversion of the funds. Clearly, the use of electrical current at the flushing station or auxiliary plant for power purposes when not necessary for lighting purposes cannot avail the respondent in this action. State v. Eau Claire, 40 Wis. 533; Bell v. Platteville, 71 Wis. 139, 36 N. W. 831. The use for power at the auxiliary plant, upon the record, would be incidental when not needed for lighting, and to economize otherwise wasted electrical energy.
But the real contention of respondent’s counsel is, not that the fund cannot be used for power purposes, but that it cannot be used for lighting purposes.
This brings us to the real contention of respondent on this appeal, namely: first, that the city has no right to use the streets for distributing the electrical energy generated by the plant; and second, that it cannot operate a plant without a certificate of convenience and necessity from the railroad commission.
Express statutory authority is conferred upon cities to light streets, public buildings and grounds. Sec. 926 — 11, Stats. (1898). Having such power, it necessarily follows that it may use the streets for the accomplishment of such purpose. Ellinwood v. Reedsburg, 91 Wis. 131, 64 N. W. 885. Whether *511the statutory authority above referred to is in any way qualified by the public utility act (Laws of 1907, ch. 499) we need not consider in this case, since we shall show later that the public utility act does not apply to the instant case. The argument of respondent to the effect that the streets cannot be used by defendant city without obtaining a certificate of convenience and necessity from the Wisconsin railroad commission, if we understand it, seems to be based upon assumed contract relations between owners of rights under the public utility law and the state. Counsel say in their brief: “But the point of cleavage clearly exists where the municipality undertakes to light its streets, erect poles, and string wires thereon in derogation of the contract between the state and the holder of an indeterminate permit within the municipality.” The appellants contend that a certificate of convenience and necessity is not necessary, for three reasons: first, that it is not necessary where a private corporation or municipality intends to construct a plant and generate electricity for the purpose of supplying its corporate needs; second, that the city having commenced construction of its plant before there was in existence in said city a plant operated under an indeterminate permit, by express provision of the statute the certificate is unnecessary; and third, that since the passage of the public utility act the legislature has expressly authorized the building of the plant without a certificate of convenience and necessity. The last two propositions, we think, control this case, and the first need not be treated. The public utility act was passed in 1907. In 1906 the defendant city issued and sold bonds for the erection and maintenance of an electric lighting plant, bought a site for that purpose, and subsequently to the issue of the 1906 bonds and in 1910 the common council of the defendant city authorized the construction of the plant in question and caused to be issued a second series of bonds by authority of a vote duly taken for that purpose. Therefore, the public utility act not having passed until July, 1907, the city, up to that time at *512least, bad a right to construct a plant without first obtaining a certificate of convenience and necessity, and it appears that the city had in fact expended upwards of $60,000 on such plant and incurred other indebtedness in that behalf. Clearly, under the law there was no duty resting upon the defendant city to obtain a certificate of convenience and necessity when there was no public utility, or when 'an existing one was operating without an indeterminate permit. Sec. 1797m— 74, subsec. 4, provides: “Nothing in this section shall be construed so as to prevent the granting of an indeterminate permit or the construction of a municipal plant where the existing public utility is operating without an indeterminate permit, as provided in this act.” Moreover, we think it clear that under ch. 75, Laws of 1911 (see. 927 — 19a, Stats.), no certificate of convenience and necessity was necessary. This act gives express authority to construct the plant in question without a certificate of convenience and necessity.
Ch. 75, Laws of 1911, provides:
“Whenever any bonds heretofore or hereafter issued and sold by any city, whether incorporated under general law or special act, for the construction or purchase or the erection and maintenance of an electric lighting plant, and the proceeds of which shall have been expended in whole or in part by such city in or about the construction or purchase of such plant, or of a site therefor, shall be invalid for any reason, and such city shall, by further proceedings subsequent to such issue, sale, and expenditure, have determined in the manner provided by law to issue bonds for the construction or purchase of an electric lighting plant,- or for the construction of a plant for the production, transmission, delivery, and furnishing of electric light for lighting streets, public grounds, and public buildings in the said city, aaid for the production, transmission, delivery and furnishing power for municipal purposes, said invalid bonds theretofore issued and sold shall, if ratified by a majority vote of the members elect of the common council of such city, be legal and binding; and such city is authorized and empowered, after such ratification, to use any property acquired with the proceeds of such bonds and *513any unexpended portion of such, proceeds in and about the construction or purchase of an electric lighting plant for which such city shall have legally determined to issue bonds as aforesaid; provided that such invalid bonds, upon being so ratified, shall not be considered an addition to the bonds legally authorized, but as a part thereof.”
The record shows that the city comes directly within the terms of ch. 75, Laws of 1911 (sec. 927 — 19a, Stats.), 'and since this law gives the right to complete the plant without any mention of certificate of convenience and necessity, it must be held that the legislature intended that none should be required.
Some reliance seems to be placed upon ch. 596, Laws of 1911, by the respondent. The constitutionality of this act is attacked by counsel for appellants. But in the view we take of the case, as heretofore indicated, we do not regard the amendment (ch. 596, Laws of 1911) applicable here, and shall not consider its constitutionality.
It follows from what has been said that the order appealed from must be reversed.
By the Court. — Order reversed, and cause remanded for further proceedings according to law.
