— The right to recover in this case is resisted by the plaintiff in error, on the ground that money paid in pursuance to, or in virtue of legal process, cannot be recovered back, so long as the proceeding under which it was paid, remain in force.
No principle of law is better settled, than that a judgment until reversed, is between the parties to it, and upon the matter determined, as a plea or bar or as evidence, conclusive. This is necessary to the repose of society; there must be an end to litigation, and it is not easy to conceive the beneficial results which flow from it, or the injury which arise from its relaxation.
In a proper case for the application, courts of justice will not permit the rule to be called in question by any supposed hardship, which can exist in any particular case; but inflexibly adhere to it. In the case of Moses v. Macfarlan, Burrow’s Rep. 1005, Lord Mansfield permitted it to be questioned; but his example has not been followed, and that case has been repeatedly overruled, and never considered as law.
The rule has been carried much farther, than here stated. In a very recent case, it was held by the court of common pleas, that where money was paid after legal process sued out recover it,|the party, knowing for what cause the action was brought, and there being no fraud, it could not be recovered back, (see Hamlet and others v. Richardson, 9 Bingham, 644; and also, *409Loring v. Mansfield, 17 Mass. Rep. 394; Morton v. Chandler, 7 Greenleaf 44; Marriott v. Hampton, 7 Term, 267; Brown v. McKinally, 1 Espinasse 279.) The same doctrine was held by this court in the case of Jones v. Watkins, 1 Stewart Rep. 80, and indeed if any principle can be considered as the settled law of this court, not open to question, cavil, or doubt, it must be this.
These positions are not directly assailed, and indeed are admitted to be true; but it is insisted by the learned counsel for the defendants in error, that money paid by compulsion of legal process, may under peculiar circumstances be recovered back; as where ignorance of law is combined with other circumstances which made it inequitable that the party thus recovering the money, should be allowed to retain it: and to support his position, he relies on the cases collated by Mr. Justice Story in his commentaries, 1 vol. 129 to 153.
It is certainly true, as stated by that distinguished jurist, that some of the old decisions of the English Chancellors, cannot be satisfactorily reconciled with the maxim that ignorance of law will not excuse; but we do not understand that he doubts what the law really is at the present day, both in England and the United States. He thus sums up the authorities on this point, at page 151.
“ We have thus gone over the principal cases, which are supposed to contain contradiction to, or exceptions to the general rule, that ignorance of the law, with a full knowledge of the facts, furnishes no ground to rescind agreements, or to set aside solemn acts of the parties. Without undertaking to assert that there are none of those cases which are inconsistent with the rule, it may be affirmed, that the real exceptions to it are few, and generally stand upon some very urgent pressure of circumstances. The rule prevails in England, in all cases of compromises of doubtful, and perhaps doubted rights; and especially, in all cases of family arrangements. It is relaxed, in cases where there is a total ignorance of title, founded in the mistake of a plain, and settled principle of law; and in cases of imposition, *410misrepresentation, undue influence, misplaced confidence, and surprise. In America the general rule has been recognized, as founded in sound wisdom and policy, and fit to be upheld with a steady confidence. And hitherto the exceptions to it (if any) will be found, not to rest upon the mere foundation of a naked mistake of law, however plain and settled the principle may be; nor upon mere ignorance of title, founded on such mistake.
“ It is matter of regret, that in the present state of the law, it is not practicable to present in any more definite form, the doctrine respecting mistakes of law; or to clear the subject from the obscurities and uncertainties which still surround it. It may, however, be added, that where a judgment is fairly obtained at law, upon a contract, and afterwards upon moresolemn consideration of the subject, the point of law upon which the cause was adjudged, is otherwise decided, no relief will be granted in equity against the judgment, upon the ground of mistake of thelaw; for that would be to open perpetual sources of litigation.” [See also Hunt v. Rousmaniere, 1 Peter’s 1; Shotwell v. Murray, 1 Johnson’s Ch. 512; Lyon v. Richmond, 2 Johnson’s Ch. 51; Lewis v. Barker, 6 Johnson’s Ch. 168] in which all the cases are collated, and the rule laid down with great clearness. So also, in this court, in the case already referred to in 1 Stewart, this court held, that money paid under ignorance of law could not be recovered back. The question in that case was presented under most imposing circumstances, and well calculated, if any thing could have that effect, to induce a departure from the rule; as many families had been reduced from wealth to indigence, by the misapprehension entertained by the whole community, of the true construction of thelaw, authorizing any amount of interest to be received, which the parties stipulated for in writing. We have considered the operation of the rule in courts of equity; at law there has been but little doubt, if any, entertained on the subject. In Bilbie v. Lunly, 2 East, 469, Lord Ellenborough held, that money paid by one, with full knowledge of the circumstances, or having the means of knowledge, could not be recovered back, because such payment had been made in ignor*411anee of the law, and asked the counsel if any case could be found to the contrary, to which no answer was given.
As the money sought to be recovered back in this case, was paid on judgments confessed, or regularly obtained with knowledge of the facts, but ignorant of the law, as afterwards settled by this court, in the case of the Trustees of the University v. Winston, 5 Stewart & Porter 17, it is fully established by all the cases cited, and by the result of the English and American authorities as collected by Judge Story, that the money could not be recovered back, even in a court of equity. It would not be necessary to add any thing further, but ps the learned counsel for the defendants in error, inveighed in strong terms, against the Trustees of the University, for retaining the money thus paid, it is but shore justice to them, as the agents of the public, to state the case correctly.
The defendant in error became one of the purchasers of a portion of the University lands in 1823, on the terms prescribed by law. One fourth part paid down, one eighth part in one year thereafter, and one eighth part in two years, with interest at six per cent, per annum, and the residue of the purchase money, in eight years from the sale with like interest; with the privilege, at the expiration of the term of credit, and the payment of one half the purchase money, to convert the sale into a perpetual lease, paying interest for ever on the sum paid. There was also a clause, that in the event the money was not punctually paid, the land.should be forfeited, unless the Trustees, within three months thereafter, commenced suit; in which event, the forfeiture was suspended, until a return of nulla bona, or non est inventus.
After a forfeiture had accrued by the terms of the law, the defendant in error, still retaining possession of the land, the Trustees commenced suits and obtained the judgments, the proceeds of which aré now sought to be recovered back. This court having in June, 1S33, at the instance of one of the purchasers, •determined, that after a forfeiture had accrued under the law, it could not be waived by the consent of either, or both parties,— *412the legislature, in January, 1834, passed an act, the title of whieh is, “for the relief of the purchasers of the University lands.”
The act appoints commissioners to value the lands thus forfeited, and which were still in the possession of the original purchasers, and gives them the right of pre-emption in the purchase of the land at their valuation; by paying one fourth part of the purchase money down, and the residue in one, two, and three years; and in assessing the value of the lands, the commissioners were required not to take into consideration thé value .of the improvements. The act, in addition thereto, gave to the purchasers, the benefit of the original contract, so far as to enable them to take a perpetual lease if they desired.
We need not recur to our knowledge of the history of this law for the fact, that it was passed at the earnest entreaty of the purchasers of the University lands. Every line, from the title to the last word, shows that the State acted with the utmost liberality; whilst the commissioners were forbidden to permit the improvements made on the land to enhance its value, full scope was given for diminishing the price down to the minimum fixed by law, by the injury done to the land by cultivation for more than ten years, and by the destruction of the forest. Yet it is this act, passed at the instance of the original purchasers and by virtue of which the testator of the defendants in error repurchased the land, that is now relied on as authorizing this recovery, on the ground, that as by the act the Legislature recognized and affirmed the forfeiture, it was a species of robbery to retain the money paid after such forfeiture had accrued.
If instead of the case being presented as it now is, of money voluntarily paid on judgments, which by lapse of time are irreversible, and as to those which were confessed could never have been reversed, there was no legal obstacle in the way toa recovery, and the question was simply whether in equity and good conscience this monéy could be retained, there could be no doubt of the result. The possession of the lands of the University for eight years after the forfeiture, the deterioration of the soil and waste of the timber, for which the trustees could main*413tain no action, or at least instituted none and asserted no claim, would have justified them in foro conscientiæ, in retaining the small amount paid after the forfeiture, which was indeed no compensation for the injury, and was both paid and received in ignorance of the law as afterwards settled. It might be added, that this ignorance of the law operated much more to the prejudice of the University than of the purchasers of the lands, and that the former was always willing to comply with the original contract, whilst the latter insisted on the forfeiture created by the statute.
It results from what has been stated, that the defendant in error cannot maintain this action, and the court erred in not instructing the jury to that effect, on the motion of the counsellor the defendants below.
Let the judgment be reversed and the cause be remanded, for further proceedings.
