MR. CHIEF JUSTICE BRANTLY
delivered the opinion of the court.
This action was brought by plaintiff, a taxpayer of the city of Helena, to enjoin the city, its mayor and council, from proceeding to construct an electric light plant, to be paid for and owned by the city, and from collecting so much of a tax of two mins levied upon the taxable property in the city as was imposed for the purpose of raising funds to aid in paying for the construction of the plant. The pleadings and evidence are voluminous, but there is no substantial controversy as to the material facts. The questions submitted for decision arise upon *502the following facts, either admitted in the pleadings or found from the evidence by the trial court: The assessed valuation of the property within the city for revenue purposes for the year 1909 was $11,200,000. The bonded indebtedness then outstanding was and now is $488,800, greatly in excess of the three per cent limit permitted by the state Constitution. These bonds having been issued several years ago, however, when the valuation of the taxable property of the city justified the amount of indebtedness represented by them, no question arises here as to their validity, though no further indebtedness may be incurred except as permitted by the Constitution, for water and sewerage purposes. The city has never heretofore owned a light plant. It and its inhabitants are at present being supplied with light by the Helena Light and Railway Company, a corporation owning and operating gas and electric light systems in the city, under a franchise granted by the city, and amply sufficient to meet all requirements. This franchise does not expire for some years, and the rates charged for public and private consumption are fixed by contract with the city which expires on May 1st of the present year. The total levy of taxes for the year 1909 to meet the current expenses of the city government up to and including the first Monday of May, 1910, was ten and three-fourths mills. Of this the fraction of a mill was a special tax authorized by the statute for free city library purposes. Its validity is not called in question. The proceeds of the levy of ten mills, together with the income derived from licenses, fines and penalties for violations of city ordinances, and other miscellaneous sources of revenue amounted approximately to $150,000, and were more than sufficient to meet current expenses, including the interest on the bonded indebtedness and such sinking fund as was required to be provided under existing provisions of law. These expenses would require a gross outlay of about $122,500. Included in the ten-mill rate were two mills levied for lighting purposes. Theretofore only one mill had been levied for this purpose. The increase of one mill was made in order to raise money to be used, together with the surplus *503funds in the city treasury, for installing the electric light plant, the purpose of which was to light the streets and buildings belonging to the city, and, if the city council should so decide, to supply the inhabitants of the city with light. On September 8, 1909, there was in the treasury of the city, in the fund designated in the ordinances as the general fund, a surplus of from ■$40,000 to $50,000. There is some controversy as to the sources from which this was derived, but for present purposes it may be assumed, as is claimed by the defendants, that it was accumulated from balances left over from year to year, of funds ■derived from sources other than taxes on property. On that date the mayor recommended to the council in writing that $25,-■000 of this surplus be transferred to a fund to be known as the electric light plant fund and to be used for equipping an ■electric light plant. This recommendation was adopted by the ■council, and thereafter, in making the usual levy of taxes for current expenses, the levy for lighting purposes was increased from one to two mills. Thereupon the mayor and council proceeded to call for sealed bids as a preliminary step for letting contracts for the purchase of materials, apparatus and machinery to be used in the installation of the lighting plant, and to that end caused to be inserted in one of the newspapers published in the city an advertisement calling for bids. The council failed to designate by ordinance or resolution the time for which the advertisement should be published. The time fixed therein for the consideration of such bids as might be made was October 18, 1909. The intention was to let contracts for the purchase of the materials required and to proceed at once to the installation of the plant. By the terms of the advertisement, the materials were to be paid for in cash. After a hearing the district court made an order directing the injunction to issued as prayed. The appeal is from the order.
Counsel have discussed in their brief some questions which have to do with the regularity of the proceedings touching the advertisment for bids for the supply of material, machinery, etc., and the availability of the surplus in the general fund *504for the purpose to which it is sought to devote it, the last arising out of the controversy as to the sources from which it was derived. The conclusion at which we have arrived, upon the fundamental question involved, renders it unnecessary to consider them. It is not a question of moment whether the proposed expenditure is to be made out of moneys properly in the general fund, and therefore available for any public purpose to which the city government may choose to devote them, or whether they are such as under the law and the ordinances applicable must be devoted exclusively to some other definite purpose. The ultimate question is: May a city, indebted beyond the limit prescribed by the Constitution (section 6, Article XIII), use its revenues, derived from any source, to acquire an electric light plant to supply itself and its inhabitants with light while it has at hand an available source of supply, which has. heretofore been, and now is, sufficient to meet all requirements? This question was answered by this court in the negative, in its decision in Helena Waterworks Co. v. City of Helena, 31 Mont. 243, 78 Pac. 220. After further consideration of the provisions of the statute applicable, we see no reason why that decision should be overruled or modified.
It was held in State ex rel. Helena Waterworks Co. v. City of Helena, 24 Mont. 521, 81 Am. St. Rep. 453, 63 Pac. 99, 55 L. R. A. 336, that the defendant city, in its embarrassed condition, could not lawfully enter into a contract for a term of years with the plaintiff waterworks company, to supply itself with water, because the result was. the creation of a debt within the meaning of the prohibition, and hence that any amount due under such a contract was not a valid claim against the city. In a subsequent decision (Helena Waterworks Co. v. City of Helena, 27 Mont. 205, 70 Pac. 513), it was held that the city could not proceed upon the “pay as you go”' plan, because-under existing provisions of law (Political Code- 1895, sections. 4811, 4812) all claims against it for services rendered or material furnished must be audited and allowed as such before they could be paid, and thus became debts within the meaning of *505the prohibition. Under these conditions the city was shorn of its power to exist as a municipality. It could not conduct its government without incurring debts. This it could not lawfully do, because it was prohibited from doing so by the Constitution; and it could not proceed upon the “pay as you go” plan, because not permitted to pay cash for services rendered or materials furnished, under the mandatory provisions of the statute supra. In order that cities laboring under such disabilities might nevertheless be able to live and continue their governmental functions until the time should arrive at which, by economy and thrift, they might be restored to their status under the general laws, the legislative assembly amended sections 4811 and 4812 of the Political Code, supra (Session Laws 1903, Chapter 30; Revised Codes, secs. 3287, 3288) so as to permit them to conduct their affairs upon a cash basis and pay reasonable and necessary current expenses out of current revenues, or in cash in advance, upon requiring indemnity in the form of a cash deposit, to be held by the treasurer; provided, however, that sufficient funds had first been set apart for the payment of interest falling due from time to time upon valid and outstanding bonded indebtedness, and any sinking fund therein provided for. They were also authorized to pay in the usual way all valid claims against funds raised by taxes specially authorized by law for the payment of such claims. The history, purpose and effect of this legislation is stated in detail in the opinion in Helena Waterworks Co. v. City of Helena, 31 Mont. 243, 78 Pac. 220, supra. The discussion need not be repeated here. The question involved was whether the city, enabled to exist and conduct its business affairs only by reasorn of the legislation referred to, was authorized to purchase pipe and material to be used in installing a water plant out of its current revenues under the head of necessary current expenses while it could secure an adequate supply from the waterworks company. Mr. Justice Holloway, speaking for the court, said: “Section 4800, Political Code [Revised Codes, see. 3259], specifies the items of expense which a city that has not reached. *506the constitutional limit of indebtedness may incur. The list of items is a long one, and evidently was meant to include every species of expense necessary to the existence, well-being, ■and prosperity of such municipality. If the legislature, in amending sections 4811 and 4812, above, had intended to extend to municipalities laboring under the disability surrounding the ■city of Helena by reason of its having reached the constitutional limit of indebtedness, authority to incur any or all ■of those items of expense enumerated in section 4800, terms sufficiently broad to indicate such purpose would doubtless have been employed. But, on the contrary, the legislative as•sembly made use of qualifying terms, which seem to indicate a purpose to limit the items to such only as are actually neces■sary to corporate existence. The terms used are ‘reasonable and necessary current expenses.’ ”
It was then pointed out that under the amended sections, ■applicable exclusively to conditions had in mind by the legislature, the authority of the city extended no further than to make expenditures both reasonable and necessary for the corporate existence of the city, and that the proposed expenditure, though entirely praiseworthy, did not, under existing circumstances, fall within the meaning of the expression “reasonable and necessary current expenses,” as employed in the statute. The concluding portion of the opinion is as follows: “If a city has so wisely administered its financial affairs that it has not reached the constitutional limit of indebtedness, every expenditure of public money made by it must be made under the very ■ eyes of its inhabitants, any one of whom is afforded an opporT tunity to inspect the items of the proposed expenditure and .register his objection to such as may appear to him unwise or ■unnecessary; for in such case every item of proposed expenditure must be incorporated in an itemized bill, duly verified, ■.filed with the city council, audited and allowed before payment •can be ordered. But the city which has reached the limit of indebtedness may proceed to pay for its reasonable, necessary ■current expenses without any bills for the same ever having *507been made out, and with no opportunity whatever for interested taxpayers to inquire into or contest the allowance of any items' of such expense. The city which has been so unfortunate as to reach the constitutional limit of indebtedness must be content thereafter, while sueh disability exists, to maintain corporate existence, leaving any and all improvements not necessary to such existence for future efforts, when, by its forced economy, the city may so far reduce its indebtedness as to be able to take its place among other cities of the state which do not labor under this disability. The legislature, in its wisdom, made provision for such continued existence, but employed terms in so doing, such as seem to indicate a legislative purpose to limit expenditure of public money to those items of expense only which may properly be designated as living expenses.”
We see no distinction between expenditures for the purpose of installing a water plant, and an outlay to install an electric light plant. The question is not whether a city may, under the power conferred by the general laws, expend its revenues to install such a permanent improvement as an electric light plant, but whether a city, in the disabled condition in which the city of Helena is, has the power, under the provision supra, to expend its revenues for such purpose. Under the rule of construction applicable, viz., that a city has no power except sueh as is conferred by legislative grant, either expressly or by necessary implication (1 Dillon on Municipal Corporations, 4th ed., see. 39; Davenport v. Kleinschmidt, 6 Mont. 502, 13 Pac. 249; City of Helena v. Kent, 32 Mont. 279, 80 Pac. 258), the power to make the proposed expenditure does not exist.
This conclusion incidentally disposes of the additional levy of a tax of one mill, the proceeds of which were intended to be devoted to the same purpose. If it is not lawful for the city to make the proposed expenditure, it certainly follows that it may not levy a tax to raise money for that purpose. It is not controverted that the levy was made to aid in installing the permanent improvement. It was therefore unauthorized. If, in fact, as is contended by counsel for defendants, the levy had *508been made generally to defray current expenses for lighting the city, the courts would not undertake to determine whether the council had exercised a proper judgment and discretion in mailing it. The record, however, shows that the purpose of it was to aid in the proposed improvement.
The order of the district court is affirmed.
Affirmed.
