The object of the bill is, to be relieved against an assessment made under the direction of the corporation of the city of New-York, to defray the expense of a large common sewer, in Canal-street, in the said *353city. The assessment was directed and made under the provision contained in the 175th section of the act of the legislature, passed the 9th of April, 1813, entitled, “an act to reduce several laws relating particularly to the city of New-York, into one act.”
By the provisions of the act, it is declared to be lawful for the corporation to cause, among other improvements, “ common sewers to be made in any part of the city, and to cause estimates of the expense to be made, and a just and equitable assessment thereof, among the owners or occupants of all the houses and lots intended to be benefitted thereby, in proportion, as nearly as possible, to the advantage which each shall be deemed to acquire, and to appoint skilful and competent disinterested persons to make every such estimate and assessment; and those persons shall take an oath to make the same fairly and impartially, and having made such estimate and assessment, shall certify the same to the common council, and being ratified by it, shall be binding and conclusive upon the owners and occupants of such lots, so to be assessed.” The bill states, that all these provisions of the act have been complied with, except, that the assessment has not embraced a sufficiently extensive district of the city, to include all the owners and occupiers of lots intended to be benefitted by the sewer. It is contended by the bill, that the owners and occupiers of all the lots from whence, by the permanent regulations of the corporation, the waste water is carried off into Canal- street, are, and were intended originally to be benefitted by the sewer, and that they ought to bear a rateable proportion of its expense. There may be an error of judgment upon this point, both in the persons who made the estimate and assessment, and in the common council who heard the objections of the plaintiffs, and yet ratified the assessment; but the greater difficulty with me is as to the question of jurisdiction. I cannot find that the Court interferes in cases of this kind, where the act com*354plained of was done fairly and impartially, according to the best judgment and discretion of the assessors; and a precedent once set, would become very embarrassing and extensive in its consequences. If the power under this statute had been exercised in bad faith, and against conscience, I might have attempted to control it; but a mere mistake of judgment in a case depending so much upon sound discretion, cannot properly be brought into review, under the ordinary powers of this Court. There must have been a thousand occasions and opportunities for the exercise of such an appellate jurisdiction, in the history of the jurisprudence and practice of the English ..Court of Chancery, if such a jurisdiction existed, and yet we find no precedents to direct us. A mistake of judgment in the assessors, upon the matter of fact, what portion or district of the city was intended to be, and actually was, benefited by the common sewer, can hardly be brought within the reach of that head of equity jurisdiction which relates to breaches of trust. Here is not, strictly speaking, a violation of duty. No bad faith or partiality in the assessors is pretended. The aid of this Court might as well be asked to review every assessment of a land tax, or a poor rate. I apprehend, it would require a special provision by statute to authorize Chancery to interfere with these assessments. Instances are numerous in the English law, in which jurisdiction is given to the Chancellor, under local or private acts; and the cases imply that a statute was requisite to give the jurisdiction.
Let us examine the case ex parte Coxall, (3 Atk. 639.) which concerned the city of London tithes, and it will afford some instruction, as to the extent of equity powers. The statute of 22 and 23 Charles II. directed that certain persons in each ward and parish, should assemble in each parish, and should “ proportionally assess upon all houses, shops, warehouses, and cellars, &c. the whole respective sum by the act appointed, in the most equal way, that the said assessors, according to the best of their judgment, could *355make it.” The act further provided, that if any difference should arise in the assessment, and a parishioner should find himself aggrieved by the assessment, an appeal lay to the Lord Mayor, and Court of Aldermen, who were to summon all parties concerned, and hear and determine the same, in a summary way, and the judgment by them given was to be “ final and without appeal.” After the assessment was made and settled, the Lord Mayor, upon refusal of any of the inhabitants to pay their assessments, was to issue his warrant of distress. The act further provided, that if the Lord Mayor or Court of Aldermen should refuse to perform any of the duties required of them, the same should be performed by the Lord Chancellor with two of the Barons of the Exchequer. Upon this act, Lord Hardwicke observed, that the authority of the great seal did not extend to every case under the act, but only where there had been a refusal, by the Lord Mayor, SfC., to execute the powers; and he, also, observed, that in case of any variance or difference between the minister and the parishioners, as to the assessment, the Court of Chancery had no jurisdiction, unless the Lord Mayor refused to take cognizance.
Lord Hardwické’s opinion equally applies to the case before me. If Chancery had no jurisdiction, when an assessment had not been proportionably made, in the most equal way, as the English statute directed, and if the only relief was in the review of the Lord Mayor and Court of Aider-men, whose decision was declared to be “ final and without appealwe are equally required to say that Chancery has no jurisdiction here, for an unequal assessment, because the Mayor, Aldermen, and Commonalty, in Common Council convened, are here, also, to ratify the assessment, which includes a review of it, and a power to correct it, if not duly and justly made; and their decision is declared to be “ binding and conclusive.”
In the case of The Attorney General v. The Foundling Hospital, (4 Bro. 165.) a bill was filed, and an injunction *356asked,'to restrairithe defendants from "building on estates "belonging to the hospital. Lord Commissioner Eyre observed, that where'trustees or governors abused’their trust, the Court could take notice of it, but where the management of a -'chhriiy was entrusted'to governors Or guardians, by statute, they'had a right to'exercise their discretion, and'though the "‘Court should-be df a different opinion, it would "not setup thát’dpinion against'the discretion of the trustees. The Other atWo Commissioners cbnctirred, arid the -motion for an injunction wás "denied. The "same -principle was admitted and "supported in Haight v. Day. (4 Johns. Ch. Rep. 18.) It -may’be said, that the assessors in this case had no discretion, but were "bound to make the assessmenfin just proportions among all the owners arid occupants beneiitted by the sewer. -The discretion in these cases, means the exercise of sound judgment according to equity — discrktio est scire per legem, quid -sit jusium; the assessors certainly had that discretion, in -determining the extent ánd value of the benefit, and their case comes within the influence and-principle of those-decisions.
If the plaintiffs are truly aggrieved, their remedy, if any they have, must be in the Supreme Court, by certiorari. In Wildy v. Washburn, (16 Johns. Rep. 50.) the Supreme "Court say, that whenever the rights of an individual are infringed by the acts of persons clothed with -authority to act, ánd who exércise that jurisdiction illegally, and to the injury of an individual, the person injured may have redress by certiorari. The same general jurisdiction of that Court -has been asserted and declared in other cases; (Kinderhook v. Claw, 15 Johns. Rep. 538. Lawton v. Cambridge, 2 Caines’ Rep. 179.) and seems to be -supported by the powers acknowledged to belong to the Court of K. B. A certiorari lies (1 Salk. 145. Anon. Holt, Ch. J., in 1 Ld. Raym. 469.) to that Court, to correct a mistake made by •commissioners of sewers; and though the K. B., in The King v. King and others, (2 Term Rep. 234.) refused that *357writ to remove the assessment of the land tax, they placed the refusal on the ground of the great public inconvenience of the step ; and for the same reason they have refused it in the case of a poor rate. But it does not belong to me, to point out or vindicate the remedy at law. It is sufficient, upon the present motion, to say, that the remedy, if any, is at law, and that it does not fall within the ordinary jurisdiction of this Court.
Motion denied.
