The plaintiff is owner of the hotel known as Fenwick Hall in the town of Old Saybrook, and of the piece of land on which the same is built. This property is *37separated from another portion of the town by an estuary of Long Island Sound, about three quarters of a mile in width. Many years ago the plaintiff or its predecessors in title, for the purpose of rendering said hotel convenient of access, expended a large sum in constructing a bridge across this estuary, and has maintained the same at its own expense. William L. Matson and others owning land in the neighborhood of the hotel, applied to the selectmen of the town to lay out a highway across the estuary, and, upon their refusal, brought an application to the Superior Court claiming a judgment for a lay-out and the assessment of damages and benefits incident thereto. In June, 1891, the Superior Court rendered judgment against the town, ordering a highway seventy feet in width to be laid out across the estuary and over the land adjoining the same (the said bridge being included within the limits of the highway), and ordering the highway so laid out to be constructed and opened for public travel on or before June 3d, 1895 ; and also rendered judgment in favor of the town to recover of the present plaintiff the sum of $5,872.10, being the amount of special benefits duly found and assessed against it; and adjudged that the present plaintiff pay said sum to said town on or before August 1st, 1891, and that said assessment be collected in the same manner as town taxes may by law be collected. The plaintiff did not pay said assessment, and the town procured a warrant to be issued for the collection of the same in the manner provided by law for the collection of town taxes. On October 10th, 1894, the collector of the town levied this warrant on the real estate of the plaintiff and advertised the same for sale at public auction according to law. The sale was adjourned from time to time, and on May 4th, 1895, the plaintiff brought this complaint asking a permanent injunction restraining the town from completing the levy of the warrant. The Superior Court rendered judgment for such permanent injunction.
The lay-out of the highway and assessment of benefits was a judicial proceeding, to which the plaintiff was duly made a party; and, as the finding shows, it did appear and was *38heard. The plaintiff therefore is bound to pay the amount assessed against it by force of a final judgment of the Superior Court, in a cause to which it was a party. The order on the plaintiff to pay the assessment, immediately became a debt; it is not distinguishable from any other judgment for debt. Welles v. Cowles, 4 Conn. 182, 188. The warrant in the hands of the collector is in the nature of an execution issued on a final judgment. The plaintiff asks the Superior Court, as a court of equity, to restrain the defendant from completing the service of this execution issued upon the final judgment of the same court rendered nearly one year before this action was commenced.
The complaint alleges three grounds on which the injunction is asked, viz.: the judgment against the plaintiff is void; the defendant has failed to comply with certain statutory requirements which must precede the collection of the amount assessed; certain events have occurred since the rendition of the judgment, which render its enforcement unjust and authorize a court of equity to interfere.
The plaintiff claims that the judgment is void, because it appears from the record of the proceeding that there has been no finding by a committee that the highway is of common convenience and necessity. The committee appointed by the court, in the report of their doings, after stating their layout of the highway, say: “ We find and report that the portion of the claimed highway laid out by us, as above set forth, is of common convenience aud necessity, and said application ought to be granted, assuming that at least $ 10,000 of assessments of special benefits by reason of said lay-out can be legally sustained; and we also find as a fact in the case, that whether the structure to be adopted be a new pile bridge, or repairs to the present pile bridge, or a permanent earthwork, or some other structure, the cost to the town of the proposed lay-out (including a fair estimate of the future cost which is certain to be incurred over and above ordinary highway repairs) will be equivalent to a present burden of not less than 122,000, and that' such an expense is beyond the financial ability of the town to sustain, and an unreason*39able burden to be placed upon the town; and we, therefore, find and report that if an assessment^ the amount at least of $10,000 as aforesaid, by reason of said lay-out, cannot be legally sustained in favor of the town, then and in such case the said lay-out of said highway is not of common convenience and necessity, and said application for a lay-out ought to be rejected.”
The plaintiff says that this is only a conditional finding; and that without an absolute finding by the committee that the highway claimed is of common convenience and necessity, the court has no jurisdiction to pass any judgment whatever, and therefore the judgment is not only voidable but void, and may be collaterally attacked by the parties to the judgment.
The Superior Court is a court of general jurisdiction. The duty of constructing and maintaining necessary highways is imposed upon towns; in.the absence of a statute, the refusal of a town to act in the performance of that duty presents a question within the jurisdiction of the court. The taking of a right of way without compensation also presents a question within the court’s jurisdiction. When the statute provides for an application to the Superior Court, upon the refusal of a town to lay out a necessary highway, it prescribes the process for bringing before the court subject-matters within its general jurisdiction, and regulates the manner of exercising that jurisdiction. The fact that incident to the final judgment to be rendered are matters that by themselves might be without its jurisdiction, and that the exercise of some special and limited powers involved should follow the statutory provisions, does not alter the material fact that the main subject-matters of this proceeding are within the general jurisdiction of the Superior Court. Its judgment in such a case is clearly distinguishable from that of an ordinary special tribunal. Avery v. Groton, 36 Conn. 304, 308. The application is in the nature of an appellate proceeding, and the only strictly jurisdictional fact, i. e., a fact whose absence from the record renders the whole proceeding coram non judiee, is the fact that the town through its selectmen has *40refused to lay out the highway ; and on this fact the finding „of the Superior Court is conclusive. Huntington v. Birch, 12 Conn. 142; Southington v. Clark, 13 id. 370, 373; Ives v. East Haven, 48 id. 272, 288. Formerly the statute provided that the court should pass upon the question of common convenience and necessity “ by committee or otherwise,” and it was held the question was properly decided by the court without appointing a committee; Windsor v. Field, 1 Conn. 279, 284; and that the acceptance of the report of a committee was a finding of common convenience and necessity. Lockwood v. Gregory, 4 Day, 407, 416. Since the statute has required the question to be sent to a committee, the conclusions of the committee cannot be altered by the court; yet their report being the action of an arm of the court and a basis of its judgment, the court has a supervisory control of the committee, and may reject or accept its report, and in doing either it is in the exercise of its jurisdiction. Winchester v. Hinsdale, 12 Conn. 85, 94, 100, 13 id. 132; Clark v. Saybrook, 21 id. 313, 319; Pierce v. Southbury, 29 id. 490; Goodwin v. Wethersfield, 43 id. 437; Hoadley v. Waterbury, 34 id. 38.
In the present case the town remonstrated against the acceptance of the report, on the ground that properly construed it did not find the highway to be of common convenience and necessity. The court overruled the remonstrance, held the committee had so found, accepted the report and rendered judgment accordingly. In this the court acted, whether correctly or not, in the exercise of its jurisdiction. Neither the town nor the present plaintiff appealed. As between them the judgment is a valid final judgment, as valid as if it had been affirmed by this court, and it cannot be attacked in this action.
For the same reason, the error of the Superior Court—if it did err—in the principles of assessment approved in its judgment, cannot affect the validity of the judgment, as between these parties. They are in this action estopped from questioning its validity in that respect; as between them it is res judicata. Terry v. Waterbury, 35 Conn. 526, 533. *41And this applies to the claim that the whole amount of benefits assessed by the committee exceeds “ one half of the estimated cost of the lay-out,” in violation of § 2720. The committee say in their report: “We estimate the cost of such lay-out to be $22,000. We estimate and determine that no person will sustain damage by said lay-out to an amount exceeding the special benefits accruing to him therefrom. We estimate and assess the following special benefits as accruing by said lay-out to the respective persons hereinafter named, over and above any damages sustained by them respectively bj' reason of said lay-out, including the value of any land taken, and of any interest in said bridge,”—amounting in the whole to $10,450. If the estimate of the committee of $22,000 as the cost of the lay-out, was wrong in law, it was nevertheless adjudged by the court, in the plain exercise of its jurisdiction, to be correct in law, and the only remedy in case of error was by appeal to this court. If the assessment of the total amount of benefits at $10,450 was wrong in fact, the remedy was to move for a re-assessment by a jury. Ho motion for re-assessment being made, the court had full power and jurisdiction to approve the assessment of the committee, and to render judgment against the respective persons assessed accordingly. The plaintiff having failed to appeal, the judgment is a valid final judgment binding on it, and it cannot in this action attack the assessment as erroneous, either in law or fact.
The plaintiff claims that the defendant cannot lawfully levy its warrant, because the report of the committee has never been recorded in the town of Old Saybrook or elsewhere. The statute (§ 2719) says that when the report “ is accepted, it shall be recorded, and said road shall be a public highway.” This is mandatory and makes it the duty of the clerk of the Superior Court to record the report when accepted. But neither the existence of the highway, nor the right to collect the damages and benefits assessed, depends on the immediate performance by the clerk of this duty, He did in fact record the report before this action was commenced. The lay-out map of the highway, made by reference a part of the *42report, was at the time filed in the office of the town clerk, and a cop3r of the judgment was afterwards recorded there; this is a proper course, but is not an essential prerequisite to the collection of the benefits assessed. It was not necessary to record the fact of the completion of the highway. Section 2704, which makes such record necessary to the collection of benefits assessed, applies to improvements made by a municipality, and not to a highway laid out by the Superior Court. Section 2962 relates to the general law of land records, and affects no question arising in this ease.
There are only two facts alleged and proved as the basis of the plaintiff’s claim, that since the rendition of the judgment events have occurred which render its enforcement unjust, and authorize a court of equity to interfere.
The first is the passage of a resolution and vote by the town of Old Sa3'brook as soon as it learne'd of the final judgment, and five days after the judgment was rendered. The resolution was: “ Resolved, That the selectmen of this town be and are hereb3r instructed and authorized to repair and put in condition for use, as soon as expedient after the first of September next, the bridge known as Fenwick Bridge, . . .; also to make demand for the pa3rment of assessments as prescribed by the court within the limit of the time specified, upon all persons mentioned in the decision aforesaid.” The vote was: “ Voted, That all assessments for Fenwick Bridge collected and paid into the town treasury shall be invested as a fund, and the income therefrom with the principal, as may be necessary, to be used in repairing said bridge.” The plaintiff claims that this vote proves that it is the intention of the town to collect the full amount of the benefits, and to invest the amount of the excess of said sum over the cost of the lay-out and construction of said highway and bridge, and to use the interest derived therefrom, and such part of the principal as may be required, for the purpose of keeping said bridge in repair; and the court below finds this intention as a fact. It is apparent, however, from the whole finding, that this is a conclusion of law from the language of the resolution and vote, and it is also apparent that such conclusion *43does not necessarily follow. The order for the construction of the highway laid out, plainly contemplated, as the bridge structure to be adopted, “a new pile bridge, or repairs to the present pile bridge; ” and if the latter structure, i. e., “ repairs to the present pile bridge,” should be adopted, it as plainly contemplated a renewal of the present pile bridge. Whether this was erroneous or not is not now an open question ; it must be accepted as valid by the plaintiff in this action. The resolution of the town declared, in pursuance of the order, that the bridge structure adopted should be “ repairs to the present pile bridge,” and appropriated the assessments to be collected to that purpose.
If, however, the plaintiff’s construction of the town vote is correct, and an intention is thereby proved of appropriating the money collected to an illegal purpose, the town may be enjoined from carrying out such wrongful intention, but the mere existence of such intention does not relieve the plaintiff of his obligation under a valid judgment, and does not entitle him to ask an injunction restraining the levy of an execution on that judgment.
The other fact is the repair by the town of the “present pile bridge,” to an extent sufficient to open the same for public travel, at a cost of $4,896.30. The trial court also finds that such repair constitutes a completion of the bridge structure ordered bj' the court. But this is a conclusion of law, and we think erroneous. It is based upon permitting the plaintiff to do the very thing the judgment estops him from doing, i. e., to contest its legality. The judgment accepts the report of the committee, finds the facts to be as stated therein, approves the legal principles on which the assessments were made, adjudges that the assessments so made by the committee are legal, and orders that the highway, including the bridge, be constructed as laid out by the committee. It is plain that the bridge structure ordered, and for the cost of which assessments of benefits were made, contemplated a bridge to be built by removing and replacing from time to time portions of the “present pile bridge.” (Whether the order also contemplated any other repairs is *44not material to the present question.) And so the plaintiff urges that because the judgment assesses benefits for a bridge built in that manner, it is in violation of statute law and illegal. He is estopped from questioning the legality of the judgment. The only ground on which he can ask an injunction is that the defendant has not yet expended more than $5,000 in construction. There is nothing in the claim that the complete construction must precede the payment of assessments ; the judgment ordered the payment of the assessments within two months from its date, while the opening of the highway for public travel was fixed for one year from its date. The remedies for compelling a town to comply with the order of the court in the construction of the bridge, are ample ; Treat v. Middletown, 8 Conn. 243, 246; General Statutes, § 2721; but a mere failure on the part of the town, does not justify the plaintiff in its disobedience to the mandate of the judgment, nor authorize the court to enjoin the town against levying the execution. Even if the judgment may be construed as requiring the town to fully complete the bridge structure ordered, on or before June 3d, 1895, the town has either failed to comply, or it has not. If it has failed, the remedy should be by mandamus or other process for compelling compliance ; but if it has complied with the judgment, the plaintiff cannot, under the claim that the judgment is erroneous, ask a court of equity to restrain the levy of an execution on a judgment whose validity it is estopped from denying, because, by reason of its own failure to appeal, it may suffer some practical injustice.
The case as presented by the record is somewhat confusing ; and the error of the trial court was apparently the natural consequence of confusion induced by the immaterial issues of fact on which the trial seems to have turned. The defendant’s second defense put in issue as facts, questions of law, as well as the very matters the plaintiff was estopped from asserting. But a careful consideration of the record discloses with reasonable certainty, that the alleged equities iix the plaintiff depend wholly upon the alleged illegality in the judgment. The question of error in the judgmexxt is not *45before us; the plaintiff cannot assert it. But assuming the judgment to be correct, it is patent that no injustice is done the plaintiff. Upon the application for a highway, the Superior Court found these facts: The construction of the highway practically meant building a road three quarters of a mile long across an estuary of the Sound. This required, to stand against high tides and heavy storms, the construction of an expensive embankment or causeway, or of a bridge which might be constructed by immediately replacing an old bridge then standing with an entirely new structure, or by replacing it by repairs from time to time. The cost to the town of the structure by repairs (including a fair estimate of the future cost which is certain to be incurred over and above ordinary highway repairs) will be equivalent to a present burden of not less than $22,000. Such an expense is beyond the financial ability of the town to sustain,'and is not required by public necessity. The highway will specially benefit adjoining proprietors to an amount equal to the damage done by using their land for the way, and $10,000 more. Taking into consideration the reduction of the burden by an assessment for this special benefit, the highway is of common convenience and necessity. Thereupon the court placed upon the town this present burden of $22,000, made bearable and lawful only by the accompanying assessment of $10,000, and assessed the proprietors $10,000, being the amount added to the present value of their property by the peculiar and special benefit, beyond any public benefit given to it by reason of the lay-out. This action of the court may or may not be legally correct. We cannot now discuss this question; but assuming, as we must for the purposes of this case, that the action of the court was legal, its practical justness and equity is beyond question.
On the other hand, the plaintiff stands in a position peculiarly offensive to a court of equity. He was made a party to the application for a highway, he appeared and was heard, he chose to submit to the judgment now claimed to be erroneous, and then refused to obey its mandate; he stood by while all other persons assessed paid their assessments, and *46the town assumed a burden it is unable to bear except as the assessments are paid, and of which it cannot now divest itself ; he has secured for his property an increased valúe equal to the amount of the assessment and, retaining the full benefit of the judgment, now asks a court of equity to relieve him from its obligation.
The principle of equity which the plaintiff invokes in its behalf, is stated by Chief Justice Church in Carrington v. Holabird, 17 Conn. 530, 537: “ Although bills in equity for injunctions against judgments, as well as new trials of actions at law, are not frequent, yet they are recognized as falling within chancery jurisdiction, and may be sustained in case of mistake and accident, when no other remedy is adequate. This jurisdiction will be exercised, when to enforce a judgment recovered is against conscience, and where the applicant had no opportunity to make defense, or was prevented by accident, or the fraud or improper management of the opposite party, and without fault on his own part.” Wells v. Bridgeport Hydraulic Co., 30 Conn. 316, 321.
The facts charged in the plaintiff’s complaint and found by the trial court, do not bring its case within this principle. It relies upon its own neglect to justify the appeal for equitable relief; it does not ask for a new trial, and whether entitled to one or not, an injunction without a new trial would be most inequitable. On the facts found, the Superior Court should have dismissed the complaint, and rendered judgment for the defendant.
The judgment of the Superior Court is reversed, and the cause remanded for entry of judgment according to law.
In this opinion the other judges concurred.
