This bill was filed in the city court in equity of Montgomery by the appellees, as owners of property on Hull street and as taxpayers of the city of Montgomery, seeking to have declared null and void a certain contract of paving said street, to restrain the city council from paying out any money thereon, and from issuing certain bonds, and from fastening on the property of complainants any assessment or liability on account of said improvement. The act of the Legislature authorized the city council to pave, or otherwise improve said street (with others). The city charter requires : “It shall be the duty of the city treasurer to advertise for sealed bids for doing all such work as the council shall determine to let out on contract. The award of each contract shall be made to the lowest responsible bidder, who shall comply with such reasonable regulations as may be prescribed before the bids are called for.” The city ordinance recited the fact that “the cost of the said paving is to be assessed against the property abutting on said street to the amount that such *121property has been benefitted by such paving or improving, not to- exceed tlie increased value of said property, by reason of tbe special benefits derived from sucb improvement,” and directed tbe city treasurer to advertise for bids for paving the streets “in accordance with tbe specifications in tlie office of tbe city engineer.” Tbe treasurer did so advertise, stating that “bids on asphalt and bitulithic pavement are requested both with a five and ten year guaranty”; and, all bids under that notice having been rejected, tbe bill alleges that tbe city council then ordered a new advertisement, and that “only bids for ten years’ maintenance be received.” Accordingly, tbe treasurer advertised for bids, stating “all bids •to be of ten years’ guaranteed maintenance.” Said advertisement also stated in a previous part of it that the street was to be paved Avith either vitrified brick, etc., “all according to plans and specifications on file in tbe city engineer’s office.”
Tbe paper Avliich is referred to as “plans and specifications” described in detail tbe manner in which tbe paving is to be done; that bond shall be given and bids must be on tbe blank form, Avhich follows, and Avhich goes more minutely into details, and provides that tbe “party of tbe second part further agrees that- for a period of two years from tbe date of the final estimate of tbe said work be will keep in good order and repair all tbe work done under this contract, except only sucb part or parts of tbe work as may have been disturbed after tbe final estimate of the same, glazing, sewers, etc., and that, Avhenever directed by said engineer,” said party would proceed to repair. This is tbe contract Avhieh was signed. Tbe complainants, both as taxpayers of tbe city and as-persons whose property is liable to tbe assessment provided for, have tbe right to invoke the aid of a court of equity to restrain the execution of contracts and tbe fastening of obligations and liens upon tbe taxpayers of tbe city, if there be no authority of law therefor. Tbe object in advertising for bids is to bring about competition, and thus get the best offer that can be obtained, so as to be able to select tbe lowest and best bidder, as tbe laAV directs. It is manifest, then, that in order to- accomplish tbe purpose tbe advertisement and *122the bids must correspond. As said by this court in another case:' “To require the bids upon one basis, and award the contract upon another, would in practical effect be an abandonment of all bids.” — Inge v. Board of Public Works, 135 Ala. 187, 200, 33 South. 678, 682, 93 Am. St. Rep. 20.
Having advertised for bids with a ten-year maintenance, the city was not authorized to close a contract with a two-year maintenance. It would be impossible to tell whether or not that was the lowest bid that could have been obtained, if the bidders had known that a two-year maintenance would be accepted. — 20 Am. & Eng. Ency. Law, p. 1169. The appellant claims that, inasmuch as the advertisement refers to the plans and specifications on file in the engineer’s office, bidders could learn from that that only a two-year maintenance clause would be required. Even if the clause in the latter part of the proposed contract could be construed as a part of the “plans and specifications” referred to, the whole paper is referred to only as a form; and, when the advertisement specially stated that a ten-year maintenance clause would, be insisted on, we cannot see how it could be understood otherwise than that, while the form of the contract would be adhered to, and the specifications as to the character of the material and work would be iusisted on, yet that the maintenance clause should be for ten years, as stated in the notice, in place of two years, as stated in the form. Appellee also insists in his brief that the treasurer was not authorized to insert the ten-year maintenance clause in the advertisement; but it is so stated in the bill, and the submission and decree in this case was on the demurrer and motion to dismiss. Besides, when the accredited officer of the city published such a notice in the newspaper of the city, and the contract was made on bids which came in in response thereto, it must be presumed that the city acquiesced in the terms of the notice. At any^ rate, these were the terms on Avhich bids were requested, and the only terms to which, bidders could respond, and it may be that contractors Avho did not care to enter into' a ten-year guaranty did not deem it necessary tn examine the plans and specifications on file.
*123The act under which the city was proceeding authorized it to “issue bonds for the purpose of paving or otherwise improving tlie streets,” and provided that “the proceeds arising from, the sale of such bonds shall be applied only to the paving or improving designated in the ordinance providing for their issue.” Loc. Acts 1900-01, pp. 1027, 1029, §§ 1, 5. The city ordinance, being “An ordinance to pave South Hull street,” etc., provided that said street should be paved, and recites that, “ás the cost of the said paving is to be assessed against the property abutting on said street, to the amount that such property has been benefited by such paving, or improvement, not to exceed the increased value of said property by reason of the special benefits derived from such improvement,” and notifies persons interested that unless they file written objections within 30 days “the city council will proceed to issue the bonds to pay for the said pavement, and make a contract for such paving.” It will be observed that neither the act nor the ordinance authorize, any contract to be made for future maintenance, or any appropriation of the money to' be raised by the sale of the bonds to the payment of any such contract.
Well-considered cases hold that, where a city is authorized to contract for paving its streets, it has no authority to incorporate in the contract an agreement for future maintenance. — Portland v. Bituminous Paving Co., 33 Or. 307, 52 Pac. 28, 44 L. R. A. 527, 72 Am. St. Rep. 713, in which case it is said that such a contract “was calculated to increase the amount of the bid, by the estimated cost of such repairs” (page 30 of 52 Pac. page 717 of 72 Am. St. Rep. [33 Or. 307, 44 L. R. A. 527]); also, “a burden was undeniably imposed upon the adjacent property heyoud such as was authorized by the charter” (page 30 of 52 Pac., page 717 of 72 Am. St. Rep. [33 Or. 307, 44 L. R. A. 527]) ; also, “the expense undertaken is indefinite and the property owner must pay for them in advance. * * * Then, it being contingent, he will be paying for repairs which may never be required” (page 31 of 52 Pac., page 717 of 72 Am. St. Rep. [33 Or. 307, 44 L. R. A. 527]) ; also, “there was an evident lack of statutory power for entering into a con*124tract for keeping and maintaining the street and pavement in repair, and consequently a want of legal authority to use the public moneys for that purpose.” Page 31 of 52 Pac., page 718 of 72 Am. St. Rep. (30 Or. 307, 44 L. R. A. 527). — Alameda Macadamising Co. v. Pringle, 130 Cal. 226, 62 Pac. 394, 52 L. R. A. 264, 80 Am. St. Rep. 124, in which case Brown v. Jenks, 98 Cal. 12, 32 Pac. 701, is quoted to the effect that “officers are provided and vested with the power and charged with the duty of seeing that such work is properly done. A bond cannot be substituted for the peifformance of this duty.” Page 395 of 62 Pac., page 126 of 80 Am. St. Rep. (130 Cal. 226, 52 L. R. A. 264).
The case of Wilson v. Trenton, 61 N. J. Law, 599, 40 Atl. 575, 44 L. R. A. 540, 68 Am. St. Rep. 714, cited by counsel for appellant, states that the contention that such' a contract enhances the price nominally charged for laying a good pavement “ignores the principle on which assessments for municipal improvements are levied in this State.' Property owners are not chargeable with the price of such improvements, but only with an equivalent for the special benefits they derive therefrom.” And hence the court argues that, as the municipality must pay all over the fair cost of laying a good pavement, the plaintiff’s complaint must be reserved until the assessment is made. But in the case now under consideration the contract is entire, so that it would be difficult, if not impossible, to tell what part of the price is for paving and wliat part for future maintenance. The ordinance treats the entire contract as the paving-contract, and provides that the city council will proceed to issue the bonds to pay. for the same. So far as the assessment is concerned, it may be true that, if the benefits should be found to- be less than the actual cost, it would not increase the amount assessed, yet, if the benefits should be found to exceed the actual costs, it would affect the amount assessed, as the only limit then would be the actual cost, and, if that had been made more than it should have been, the property owner would have much more to pay than he was liable for. However, this bill is filed, not only in the capacity of abutting owners, but also as taxpayers, and under the authorities cited, *125which, we think are supported by sound reason, it is a question of power, and the city has no power to make the contract and to use the money, the proceeds of the sale of the bonds, in the manner proposed by the ordinance. The taxpayer has the right to enjoin the same. 20 Am. & Eng. Ency. Law, p. 1231.
The decree of the court is affirmed.
