This action was brought by plaintiff, as a taxpayer of the city of San Bernardino, to obtain a judgment against the defendants to the effect that a certain contract which had been entered into between them for the furnishing of illuminating light to the city of San Bernardino was void. A general demurrer to the complaint was sustained. Judgment followed for defendants and plaintiff appeals.

The city of San Bernardino called for proposals and bids for the furnishing of electric light to the city under section 140 of its charter. The section provides that no. supplies, material, or other item of expenditure, for an amount exceeding three hundred dollars, except for personal services, shall be ordered or purchased by the mayor and common council, except after first advertising for sealed proposals, and awarding the contract to the lowest and best bidder, “which proposal must be accompanied by a certified check in an amount not less than ten per cent of the sum bid, which check must be forfeited to the city upon failure of the person, firm, or corporation bidding to enter into the contract awarded”; and a sufficient bond payable to the city, with two or more sureties, or a surety company bond, shall be required to secure a faithful performance of each contract awarded.

The propositions advanced by appellant against the contract, and upon which he asserts it to be absolutely void, are based upon what he conceives to be violations of this provision of the charter. Herein he contends that the contract is void because the call for bids did not specify any particular number of lights, nor the candle-power thereof, which the city would require. In this respect, the bid of the Power Company, which is set forth at length in the complaint, shows that the company agreed to furnish such a number of lamps and lights as the city might require, describing the lamps and their candle-power at the price of $4.49 for each lamp during each and every calendar month of the term. The call for the proposals declared that the bidder should furnish a statement of detail of the kind of light he proposes to furnish, the candle-power thereof and the price, for each light, per month, or otherwise.

It is next contended that the certified check with which the defendant power company accompanied its bid was only for fifty dollars, and that under the nature of the call for bids, no bidder could tell what amount should be named in the certified check accompanying the bid; and

Finally, it is urged that the provisions of the charter do not admit of the making of a contract containing the uncertain element as to the number of lamps, or lights, which the city might require; that, in . other words, the call for bids should have prescribed the precise number of lights which the needs of the city exacted.

Upon all these points, as appellant declares, he relies on the familiar principle that the mode prescribed by the charter of the city is the only mode for the exercise of the power conferred, and that in the respects above enumerated there is a departure from that mode so flagrant as to render the contract void. Respondent makes answer that the charter provision in question has no applicability to a contract of a city for supplying it with gas, or other illuminating light, and that such has been held where the question was the furnishing of a municipality with water (Contra Costa Water Co. v. Breed, 139 Cal. 432 , [ 73 Pac. 189 ], that the same reasoning and rule under section 19 of article XI of the constitution, should apply to the furnishing of light (Den ninger v. Recorder’s Court, 145 Cal. 632 , [ 79 Pac. 360 ] ; Harlem Gas Co. v. New York, 33 N. Y. 309 ). But, without pausing to decide this question, and for the purposes of this case, taking the position which most strongly favors the appellant, we are still of the opinion that the trial court’s ruling, sustaining the demurrer, was sound. The first objection, that the council should have fixed the absolute number of lights required, upon which number alone proposals were to be received, is not sustained by reason or authority. It was the duty of the officers of the municipality to provide the city with adequate light. As the city should increase or decrease in population, more or fewer lights would be required. It would be absurd to exact that the city should advertise for and specify the number of lights, when during the life of the contract its need might be for five times the number, or, upon the other hand, when from calamity, or other cause, its necessities might be reduced to one fourth of the prescribed number. The simple,, direct, and understandable method Was that employed, to call for a supply of lights of designated character and candle-power, burning for a designated time, at so much per week or month. This was the method adopted, and is the general method (State v. City of Phillips-burg, 23 Mont. 16 , [ 57 Pac. 405 ] ; Baxter Springs v. Baxter L. & P. Co., 64 Kan. 591 , [ 68 Pac. 64 ] ; Vincennes v. Citizens’ G. & L. Co., 132 Ind. 114 , [ 31 N. E. 573 ], 16 L. R A. 487 ; Town of Colorado City v. Townsend, 9 Colo. App. 249 , [47 Pac. 663] ; Altgelt v. San Antonio, 81 Tex. 436 , [ 17 S. W. 75 ], 13 L. R. A. 386 ; Illinois Trust and Savings Bank v. Arkansas City, 76 Fed. 271 , [ 22 C. C. A. 171 ].

The second contention of appellant that the bid of the power company was not accompanied by a certified check to the amount of ten per cent of the bid is equally untenable. In the first place, it would be difficult under the circumstances of this bid for the company to have determined with exactness what would- have amounted to ten per cent and a court would be reluctant in such a case where a bona fide bid was presented to overthrow it upon such narrow ground. But, of more consequence still, is this consideration: the requirement that a certified check for ten per cent of the amount shall accompany the bid is one wholly for the benefit of the city to avoid possible loss in the event that the successful bidder should refuse to enter into the contract, thus, perhaps, entailing the necessity of re-advertising. It is conceivable that a taxpayer might have a grievance which would be heard in court to prevent the consideration by the officials of such a bid not so accompanied by the ten-per-cent certified check, but that grievance is certainly at an end when the bidder, in good faith, and under an approved bond, has entered into the contract. Such is the condition here. The purpose of the requirement was at an end when the contract was entered into, and as this proceeding is brought after that fact and to avoid the very contract, the appellant is without standing upon this proposition.

The judgment appealed from is, therefore, affirmed.
