Ye shall confine our examination to such of the alleged errors as were relied on by counsel for the plaintiff in error in argument as ground for a reversal of the judgment. And, first, did the court below err in sustaining the demurrer “ to the fourth, fifth, and seventh defenses ” of the answer ?
It seems that at the time in question there existed a contract between the’ plaintiff in error and the defendant company, whereby the latter was to furnish to the city, at a stated price per month, gaslight for its streets, etc. That, while the company was engaged in the due performance of this contract on its part, the city authorities undertook to rescind it, and to that end passed the resolution, and gave the notice to the company, which form the basis of this fourth defense or answer, and which was in these words, viz.: “ Eor a fourth, further, and separate defense to said alleged cause of action defendant alleges that, on or about the 11th day of June, 1877, defendant, by a resolution of *343its common council, approved by the mayor, declared said alleged contract at an end, and wholly rescinded; and on that day duly notified the plaintiff of such action ; and that, from that time on, said contract was wholly rescinded; and directed plaintiff to furnish no more gas or light, and to light no more lamps, and to do nothing more whatever under said contract or modifications.”
We do not think that what is thus set forth shows a rescission of the contract. It is only a declaration on behalf of the city to that effect, but to which it is not shown that the company had in any way assented. Generally a contract cannot be rescinded, unless by consent of all the parties to it, except in cases of fraud. Chitty on Contracts, 640. Therefore, there being neither assent nor fraud on the part of the gas company shown, it is clear that the contract remained in full force, notwithstanding this declaration of the city authorities to the contrary. But, although no rescission is shown, there is one material allegation which, admitted to be true, as by the demurrer it is, has an important bearing on the rights of the parties in this action. That allegation is, that on the 11th of June the gas company was duly notified and requested “ to furnish no more gas or light, and to light no more lamps, and to do nothing more whatever under said contract.”
As we understand the law applicable in such cases, it gave to the city, notwithstanding the contract, the absolute right' at its own election to decline to receive any more gas under it, thereby refusing performance on its part. Clark v. Marsiglia, 1 Denio, 317. The taking of this step, however, did not amount to a rescission of the contract, but simply a breach of it, for which the company, in a proper action, would be entitled to recover adequate damages. But in such ac*344tion the contract price of the gas furnished, after the refusal to receive it, would not necessarily be the meas-sure of damages recoverable.
And in this connection it is proper to refer to an item of evidence, the rejection,of which is alleged for error. We allude to the notice given to the company, in pursuance of a resolution of the city council, to desist from further supplying gaslight to the city under said contract. As the pleadings stood at the time of the trial, by reason of the sustaining of the demurrer, to this fourth count of the answer, the rejection of this evidence on the ground of immateriality or incompetency was not error. The error lay back of this, and in holding, on the demurrer, that such notice was of no consequence.
By the fifth defense in the answer it was alleged in effect that, by the terms of the contract in question, the franchise and property of the company, employed in the manufacture of gas, were exempted from taxation for several years for municipal purposes, by reason of which there was lost to the city the sum of $4,200, which it should have received from said company as its proportionate contribution to the municipal revenues during that time.
As to the validity of this exemption, and whether it was a binding agreement, it is not necessary here to decide; but if it were, very respectable authority is cited by counsel for the defendant in error to sustain him in his claim that it was enforceable against the city on the theory that it was an indirect mode of making payment in part for gas supplied. Grant v. City of Davenport, 26 Iowa, 396. Howsoever this may be, there is another very conclusive answer to this pretended set-off, which is, that for those years there was neither an assessment of said property, nor the levy of-a tax upon it for city purposes, without which there *345could be no valid claim against tbe company for co£ltribution to the public revenue. Mr. Cooley in his treatise on taxation says: “ Of the necessity of an assessment no question can be made. Taxes by valuation cannot be apportioned without it. Moreover, it is the first step in the proceedings against individuals subject to taxation, and is the foundation of all which follow it. Without an assessment they have no support, and are nullities.” Thurston v. Little, 3 Mass., 429. People v. Hastings, 29 Cal., 449. No tax is due unless it is assessed. Miller v. Hale, 26 Penn. St., 432.
The seventh defense of the answer alleges in substance that taxes for the year 1876 to the amount of $106.54 were levied and assessed on the capital stock of the gas company, which are delinquent and have never been paid, and that the same should be set off against claim of the plaintiff below.
By thé demurrer to this defense of the answer, the question is raised whether, prior to the act of March 1st, 1879, providing “a system of revenue,” and taking effect September 1st, 1879, delinquent taxes due from the plaintiff below to the city are a proper subject of set-off? Whether they would be under that act is a question that is not now presented, and which we do not decide. .
Section 104 of the code of civil procedure (Gen. Stat., 541) provides as to set-off, that it “ can only be pleaded in an action founded on contract, and must be a cause of action arising upon contract, or ascertained by the decision of the court.” Now taxes neither arise upon contract either express or implied, nor-is the amount thereof determinable by the judgment of a court. They are the forcible, and, within constitutional limits, the arbitrary exactions of the government for its support and use, taken from the substance of the people, “ and to the making or enforcing of which their assent indi*346vidually is not required.” Pierce v. City of Boston, 3 Met., 520. Carondelet v. Picot, 38 Mo., 125. And of the enforcement of payment, Mr. Cooley says : “Taxes are not debts in the ordinary sense of that term, and their collection will, in general, depend on the remedies given by statute for their enforcement. When no remedy is specially provided, a remedy by suit may faii’ly be implied, but when oxxe is given which does not embrace an actioxx at law, a tax cannot in general be recovered in a common law action as a debt.” Cooley on Taxation, 13. And in Carondelet v. Picot, 38 Mo., 125, the court say: “Unless the power is specifically delegated or expressed, no right of action exists for taxes, and they cannot be turned into judgments. Both the state and muxiicipal corporations-have a much better axid more expeditious remedy. • They have the right of summary process to enforce collection by levy and saleand when this power exists, complete and ample as it most assuredly is, it would be monstrous, without plain axxd express authority to that effect, to say that they could abandon at pleasure the usual and simple manner of making collections, and subject the delinquent taxpayer to all the embarrassments, vexations, and costs of a legal proceeding.” See also on this point, Turnpike Co. v. Gould, 6 Mass., 40. Packard v. Tisdale, 50 Me., 376. Perry v. Washburn, 20 Cal., 318. Richards v. Stogsdell, 21 Ind., 74. Lane Co. v. Oregon, 7 Wall., 71. Shaw v. Pickett, 26 Vt., 486.
In Turnpike Co. v. Gould, this language is used: “ Whexi we fixxd a power in the plaintiff to make the assessments, they can exxforce the payment ixx the method directed by the statute, and not otherwise; aixd that method is by the sale of the delinquent shares. This rule applies to all taxes, public aixd private.' No action can be xnaintained to compel the payment of *347state, county, or, town taxes, except in the particular cases in which an action is given by statute.” Such being the general rule when there is an efficient and summary mode specially provided for their collection, as has heretofore been the case respecting all taxes imposed in this state, under the authority thereof, whether general or special, it follows that the demurrer to this branch of the answer was properly sustained.
It is further contended that the court erred in admitting in evidence the written contract as shown on page thirty-six of the record. This instrument bears date of February 1st, 1877, and is but a slight modification of the then subsisting contract of September 4th, 1873, under which the city was then being supplied with gaslight. By this modification it appears that the amount of each monthly installment payable to the company, thenceforward to August 1st of that year, was reduced from the sum of $500.00 to $291.66. The object in giving this bit of evidence probably was to show the price for the month of June, 1877, for which the action was brought, as this month was within the above modification. And for this purpose it was clearly admissible, although under the admissions of ‘the answer it was not really necessary to introduce any testimony on this point. The answer, after setting out pretty fully the'contract of September 4th, 1873, and the modification thereto of February 1st, 1877, concludes in these words: “ That the said instrument of September 4th, 1873, and the modifications aforesaid, are the same contracts mentioned in plaintiff’s petition as the basis of its alleged cause of action herein.” In this particular there was no error committed.
It is urged, however, as against any recovery by the company under these contracts, that they cqntain certain illegal provisions respecting the exemption of property from taxation, and the payment of money *348out of the sinking fund of the city, devoted by law to another purpose. But even admitting that in these two particulars the city authorities exceeded their powers (which, how’ever, we do not decide), that would be no defense to this action. Under the charter they were authorized to contract for lighting the streets with gas, and to bind the city for the payment of the price agreed upon. In this respect, therefore, the contract was not ultra vires, and so'long as the city voluntarily received gaslight under its provisions, it cannot resist payment of the agreed price, simply because of these alleged illegal promises as to the particular fund from which the money should be drawn. The consideration for which these promises were made being entirely legal, and the price agreed upon being payable, if not otherwise, from its general fund, these objectionable provisions may, if necessary, be rejected, and the rest of the contract permitted to stand; especially where, as here, the city has received the consideration for which the promises were made. Cliittv on Contracts, 574. If the company were resisting a tax levied in violation of this agreement, or if they were-endeavoring to compel payment of a gas bill out of the sinking fund, the ai’gument of counsel for the city in this behalf would be entitled to great weight, but under the issues of this case we deem it altogether inapplicable.
Only one point more is it necessary to notice. It is contended that before the city could lawfully have entered into this contract an‘estimate of the jn’obable expense must have been made, as provided in section thirty-two of the act relating to the incorporation of cities of the second class. (Gen. Stat., 151.) But we think otherwise. This section has no application to contracts of this description, but to those respecting streets, bridges, or other work or improvement to be *349made for and owned by the city. Es language on this subject is: “ Before the city council shall make any contract for building bridges or side-walks, or for any work on streets, or for any other work or improvements, an estimate of the cost thereof shall be made by the city engineer and submitted to the council, and no contract shall be entered into for any work nr improvement for a price exceeding such estimate,"” etc. Now, all that was contracted for here was the supplying the city with light, not for the erection of gas works, to be owned and operated by the city. And the contract was made with the company, which had the exclusive right to' that business within the city, the only source from which such light could have been obtained. Clearly this section of the statute has no application here, and the argument based upon it falls to the ground.
The sole material error found in this record lies in the exclusion of the partial defense set out in the fourth paragraph of the answer, and based upon the notice of the 11th of June to the company to furnish no more gaslight to the city under said contract. Eor that error, however, the judgment must be reversed, and the cause remanded to the court below, to be proceeded with according to the views expressed in this opinion.
Eeversed and remanded.
