This is an action under § 8040 of the General Statutes, to have certain liens upon real estate adjudged invalid. The case comes to this court by reservation upon a statement of facts, of which the following is the substance :—
Prior to December 13th, 1873, four assessments of benefits, amounting in all to nearly $2,000, were laid under the charter of the city of New Haven, against certain real estate of the plaintiff in said city, on account of the construction of a public sewer. These assessments were legally laid, and would, if unappealed from, have become payable on December 13th, 1873; but prior to that day the plaintiff, under the charter, took an appeal from said assessments to the Superior Court. On February 11th, 1874, and while said appeal was pending, four certificates of lien, on account of said assessments against said real estate, were filed in the town clerk’s office in New Haven, for the purpose of continuing the liens upon said real estate, under § 37 of the then city charter. Said appeal was finally determined in the Superior Court on the 29th of November, 1892, and the assessments in question were by that tribunal confirmed, with costs against the present plaintiff. Afterwards, in March 1893, the plaintiff paid to the proper officer of said city, the amount of the four assessments, with interest only from November 29th, 1892, which amount was tendered and received without prejudice to the rights of either party. On receipt of this money the defendant discharged two of the liens, but refused and still refuses to discharge the other two. This refusal was and is based on the claim that the assessments in question carried interest, either from Decern' *166ber 13th, 1873, or at least from the time the certificates of lien were filed in 1874. If this claim is correct, the defendant is justified in his refusal to discharge the liens. On the other hand the plaintiff claims that interest was due only from the date of the final determination of the appeal in the Superior Court in 1892; and if this claim is correct, it is found that the plaintiff “ tendered to the tax collector all that was due on said assessments on March 23rd, 1893. ” If, then, the plaintiff’s claim is correct, judgment must be advised for it; otherwise for the defendant.
Passing the first point made in the plaintiff’s brief, his claim is based upon three propositions: first, that these assessments were really taxes; second, that as taxes, interest as such, or by way of penalty upon them, cannot be collected, unless the power to do so is conferred by law; and third, that no such power was so conferred upon any one with reference to the assessments in question. If these propositions are true, and we think they are, the plaintiff’s claim must be sustained.
That assessments, like those in question here, upon specific property specially benefited by a local public improvement, for the purpose of paying the expense of that improvement, are taxes, is too well settled to require extended argument. Such assessments are enforced proportional contributions of a somewhat special kind, made in invitum, by virtue of legislative authority conferred upon the municipality for that purpose, upon such terms and conditions as the legislature within constitutional limits sees fit to impose. The power thus conferred is essentially a power to tax; its exercise in the manner prescribed is a mode of taxation ; and the sums raised b}r such exercise are taxes, and are always treated as such. Such assessments are not liable to set-off, nor attachment, as debts; and they can be collected summarily by the tax collector, in like manner as ordinary taxes, if the-legislature sees fit to authorize such method, without the aid of courts and without the delay incident thereto. Assessments of benefits caused by the layout or alteration of highways may, by statute, “ be collected in the same manner as town taxes are *167collected”; General Statutes, § 2705; and the assessments of benefits under the charter of New Haven, like those in question, were treated by the legislature as taxes, and were made collectible by the tax collector in the same manner as any other tax. Charter of 1869, § 50. It is true, provision is also made in the charter for collecting such assessments by proceedings in the nature of a foreclosure of a tax lien ; but this does not alter the nature of the sum to be collected; the proceeding by way of foreclosure was in effect only another method which the tax collector was authorized to employ to collect the tax. But the decision of this court in Nichols v. Bridgeport, 23 Conn., 189, approved in Bridgeport v. B. B. Co., 36 id., 255, is so conclusive upon this first point in favor of the plaintiff, as to render unnecessary further argument or citation of authority.
The second proposition,'to the effect that a tax carries no interest as such, nor by way of penalty for non-payment, unless the law so provides, is, we also think, a correct statement of the law. Most of the cases in which interest may be recovered under our law, in the absence of any statute regulating the matter, are enumerated in Selleck v. French, 1 Conn., 32, and clearly assessments of this kind do not come within any of the classes of cases there enumerated. It will, we think, also be found true that whenever taxes have carried interest, either as such, or by way of penalty, it has been by virtue of some statutory provision to that effect. And this is as it should be. At best a tax is a burden, a necessary one it is true, but none the less a burden, imposed on the taxpayer without reference to his consent; and it seems reasonable to hold that any increase of that burden by way of penalty or otherwise, should be expressly made by the power which imposes it; and that until the legislative will to increase the burden by the addition of interest has been clearly expressed, interest should not be allowed. This conclusion, which on principle seems reasonable, is supported more or less strongly by the following authorities : City of Camden v. Allen, 26 N. J. L., 398 ; Town of Belvidere v. R. R. Co., 5 Vr., 193; Brennert v. Farrier, 47 N. J. L., 75 ; *168Danforth v. Williams, 9 Mass., 324; Shaw v. Peckett, 26 Vt., 482; Perry v. Washburn, 20 Cal., 318 ; People v. Gold and Stock Tel. Co., 98 N. Y., 67 ; Western Union Tel. Co. v. State, 55 Tex., 314; Cooley on Taxation, 300, note 4.
We think the above rule thus applied in the case of taxes as ordinarily laid, is applicable to the kind of taxes here in question; and that unless some public statute, or the city charter, expressly or by clear implication, authorized the collection of interest as claimed by the defendant upon the assessments in question, it was not collectible.
The remaining question then, is whether such authority was conferred upon any one, either by some public statute or by the city charter.
At the time these assessments were made in 1873, and ever since, interest was and has been collectible on overdue ordinary taxes in New Haven, under the provisions contained in Title 64, Chap. 2 of the General Statutes of 1866, which are still in force in that city (see General Statutes, 1875, p. 552; Charter of 1869, § 50 ; Charter of 1881, § 14; and Charter of 1890, § 14) ; but it is not claimed, nor can it reasonably be claimed, that the aforesaid provisions are applicable to the assessments here in question; for those provisions clearly relate solely and only to ordinary taxes laid in the ordinary way by the city or town of New Haven, or school districts therein; and although we hold an assessment of benefits to be a, tax, it is clearly not a tax of the kind specified in those provisions.
Section 2704 of the General Statutes (1888) provides that when assessments of benefits shall be laid by any municipality upon property specially benefited by any public work or improvement, and a certificate of lien therefor has been filed, “neither the principal of such assessment nor any interest thereon shall be collectible by such municipality,” until the work is completed and the fact of such completion duly recorded.
It may be said that this statute recognizes, by implication at least, the right to collect interest upon such assessments where a lien has been filed; and with proper limitations this *169may be conceded; for we think it does recognize such right, but only in cases where the right already exists; it does not create, nor was it intended to create, such right. That statute was passed in 1883, ten years after these assessments were made, and its plain and obvious purpose was, not to confer power to collect interest on such assessments where it did not already exist, but to prevent municipalities from collecting any part of the assessed benefits, until such benefits had been conferred by the completion of the public work.
We have failed to find any other public statute relating to this matter; and perhaps we ought to say that counsel for defendant did not claim that there was airy such public statute, but rested his contention solely upon the provisions of the city charter.
After a somewhat careful examination of the charter of 1869 (the one in force in 1873), and of the charters of 1881 and 1890, we can find no power conferred, either expressly or by fair implication, to collect the interest here claimed by the defendant. In short we know of no statute, public or private, which conferred this power with reference to these assessments. It is true, that a by-law of the city, existing in 1873, and in substantially the same form ever since, provides for the payment of interest upon liens of this kind from the date of the certificate of lien; but no provision in the charter has been found, or pointed out to us, which gave the Common Council power to make a by-law exacting interest in such a case; and in the absence of such provision, the by-law can, in this respect, have no force; and indeed upon the argument counsel for the defendant made no claim under the by-law.
For the reasons given we think the defendant was not entitled to interest upon these assessments for the period between the dates of the certificates of lien and November 29th, 1892, and that the claim of the plaintiff upon this point must be sustained.
The plaintiff also claimed that, even assuming that interest was collectible by law upon assessments unappealed from after they became payable under the provisions of the char*170ter and by-laws of the city, the appealed assessments here in question did not, under those provisions, become due and payable till November 29th, 1892. In the view already taken of this case, we deem it unnecessary to consider or decide the questions involved in this claim.
The Superior Court is advised to.render judgment for the plaintiff.
In this opinion the other judges concurred.
