The charter of the city of Racine does not require that contracts for building sidewalks shall be let to the lowest bidder, after advertising for proposals therefor. lienee such *245contracts may be made by private agreement between the city and the person contracting to build them. Rut, on general principles of law, such contracts must be fairly entered into at reasonable prices, and with due regard to the interests of the owners of lots chargeable with the cost of the improvement, and, if not so made, courts of equity will give relief to such owners on equitable principles. The evidence is overwhelming that, before the contract was let to the defendant Morey, Mr. Knight proposed to the two aldermen having the matter in charge, to build the sidewalk in question for twenty-five cents per foot, and that the price named would have been a liberal compensation for building it.
That Mr. Knight had an interview on the subject with each alderman, separately, before the contract was made with Morey, is undisputed. Mr. Knight testified to his proposal in those interviews to do the work at twenty-five cents per foot, and three witnesses swear to a subsequent conversation between him and one of the aldermen in which the proposal was substantially admitted. This conversation is not denied. There are other facts in the case, which we forbear to state, that strongly corroborate Mr. Knight’s testimony. Opposed to this there is nothing but the'statement of the aldermen that they did not recollect that the proposal was made. The evidence to prove the proposal is direct, positive and satisfactory; the evidence to disprove it is purely negative. The positive proof must prevail. Ralph v. Railway Co., 32 Wis., 177.
On the subject of value, Mr. Knight testified that twenty-five cents per foot was a good, fair price, and would yield a profit to the contractor. . Dr. Lukes, an alderman, testified that the fair value was from twenty to twenty-two cents per foot; and on cross examination he stated that in the same year he let contracts to build similar sidewalks in his ward at twenty-two cents per foot, and that the contractor could make a profit on the job at that price. The only testimony which impeaches the statements of Knight and Lukes in the slight*246est degree, is that of the two aldermen who let the contract to Morey; one of whom merely stated that the city had been in the habit of paying forty cents per foot, and the other that he knew of no case, except the one mentioned by Lukes, where sidewalks had been let for twenty-five cents per foot.
There is nothing in the record which tends to impeach the credibility of either Knight or Lukes, or which raises even a suspicion that the former was not perfectly responsible for the performance of the contract had it been awarded to him. Being satisfied, by what we deem a clear preponderance of proof, that the work was let at an unreasonably high price, in disregard of the rights of the plaintiifj we cannot uphold the special assessment for the excess above a fair price for the work. The. plaintiff should not be relieved, however, from paying a reasonable sum for the improvement. She is in a court of equity, asking the interposition of the court to restrain the collection of the assessment by injunction. The sidewalk has been constructed by order of the common council, her property has been benefited by the improvement, and the sum which she ought to pay for it is definitely ascertained by the proofs.
It is not thought necessaiy to pass upon the question, which was considerably argued, whether it is competent for the common council, under the city charter, to delegate to the aldermen of a ward power to make contracts like that under consideration. The determination of that question either way would not, we think, affect our judgment on this appeal. Doubtless the safer practice would be for the council to withhold from the aldermen, or any other officer of the city, the authority to-close a contract on behalf of the city until the proposed terms of it have been submitted to and approved by the council.
The judgment of the circuit court, so far as it affects the assessment held tó be valid, must be reversed, and the cause will be remanded with directions to that court to grant the relief demanded in the complaint, if, within some reasonable *247time to be specified by it, the plaintiff pay into court on ae-. count of such assessment, for the use of the holder of the certificate, a sum equal to twenty-five cents per, lineal foot, and interest thereon at seven per cent, from the time the lot would, but for the injunction, have been sold for non-payment of the assessment. Railing such payment, the complaint in respect to such assessment, so held valid by the circuit court, must be dismissed.
By the Court.— So ordered.
