dissenting. I am unable, after mature deliberation, to concur with the majority of the court in the opinion that the defendant is entitled to judgment; and a strong conviction that it is erroneous induces me to state the reasons why I dissent from it.
The'action is brought to recover back the money paid by the plaintiff to the defendant in the execution on her part of a contract alleged by her to have been induced by the common mistake of the parties respecting a material fact, and made upon a consideration which has wholly failed. The contract, the payment of the money, the mistake and its materiality and controlling influence, and the failure of consideration, are all clearly established. This will be readily seen upon a recurrence to the facts stated in the report which were found upon the trial.
1. The estate concerning which the contract was made, and which consisted of certain factory property, real and personal, in North Oxford, was formerly owned, subject to one or 'more outstanding mortgages, by H. D. Stone. William M. Bickford and Fitzroy Willard, asserting and claiming that Stone had become insolvent, and that in due course of legal proceedings they had been chosen and appointed his assignees, and that all *534his estate, real and personal, had been duly transferred and assigned to them by the judge of the court of insolvency, and assuming to exercise the rights and powers of such assignees, advertised that they would sell the said estate at public auction on the 24th day of July 1858. The defendant attended at the time and place of such advertised sale, and purchased the estate, being the highest bidder therefor, for the sum of $3200. This purchase was made in pursuance of a previous arrangement between him, the plaintiff and H. H. Chamberlin, by which he was to buy the estate of the supposed assignees, and was to hold one undivided half of it as his own property, and to convey one undivided fourth part thereof to the plaintiff and a like undivided fourth part to Chamberlin. Accordingly the defendant paid $1600, and the plaintiff and Chamberlin each paid $800, to said Bickford and Willard; and on the 26th day of the same month they by their quitclaim deed of said estate conveyed to the defendant “ all the right, title and interest which the said Stone had therein on the 10th day of February 1858, that being the date of the first publication of proceedings in insolvency against him.” Nothing further was done by the parties in pursuance of said arrangement between the defendant, the plaintiff and Chamberlin ; but on the next day, the 27th of July, they made a “ new bargain,” by the terms of which De Witt agreed to convey the whole estate in equal shares to the plaintiff and Chamberlin, in consideration of which they agreed to assume the consideration paid for the conveyance from Bickford and Willard, and to pay him the further sum of $6000, in equal proportions. As he then held one undivided half of the whole estate, for which they had paid the purchase money, in trust for them, and was bound to convey one undivided fourth part thereof severally to the plaintiff and to Chamberlin on de mand, it is obvious that his agreement to convey “ the whole estate ” to them was a contract to sell and convey to them, in equal shares, for the consideration named, the other half of the same estate, that is, all the right and interest which Stone had therein on the day of the date of the first publication of the proceedings in insolvency. Livermore v. Aldrich, 5 Cush. 431. *535This is shown not only by the facts above stated, but also by the description in the deeds made by him; that in the deed to the plaintiff being “ all the right and interest in one undivided half of the real and personal estate in Oxford formerly belonging to Henry D. Stone of Worcester, this day conveyed to me by William M. Bickford and Fitzroy Willard, assignees of said Stone, which I have under and by virtue of said deed from Bickford and Willard.” It is evident, therefore, that, the “ new bargain ” made by the parties was a contract that the defendant should sell- and convey, and that the plaintiff and Chamberlin should purchase and pay for, the right and interest which Stone had formerly owned and held in the premises.
2. In the intended and supposed execution of this contract, the defendant made and delivered to the plaintiff his quitclaim deed, containing a description of the estate in the terms above mentioned, and she at the same time paid to him the sum of $3800
3. When this contract was made, and when said deed was delivered and said money was paid, all the parties supposed and believed that Bickford and Willard had been legally constituted the assignees of Stone, and consequently that his interest in the estate had been duly assigned and transferred to them, and that they had ample power and lawful authority to sell and convey it to others. This belief was a mistake of fact. Such a mistake occurs whenever some fact which really exists is unknown, or some fact is supposed to exist which really does not exist. Mowatt v. Wright, 1 Wend. 355. The mistake in this instance was of the latter description. It was one into which, from the circumstances well known to have occurred, the parties would be very liable and very likely to fall. For there had been certain proceedings, purporting to be the acts, decrees and judgments of the court of insolvency, under and by force of which Bickford and Willard had been appointed and constituted the assignees of Stone. But all these proceedings were afterwards ascertained to have been illegal and nugatory; and on the 4th of February 1860, by a decree of this court in the case of Grafton Bank v. Bickford, 13 Gray, 564, they were wholly set aside and annulled ; and then the mistake under which they had *536acted became apparent. Denny v. Mattoon, 2 Allen, 361. There had been no error or misapprehension in the mind of any one of the parties in relation to the law. They all understood perfectly well what that was. They knew that if the proceedings above referred to had been regularly conducted and pursued under the statute, and in conformity to its provisions and requirements, the whole title which Stone once had in the estate would have become vested by operation of law in Bickford and Willard, as his assignees ; that they would thereby have acquired the right and power to dispose of it, and that their deed would be a legal and effectual conveyance of it to their grantee. As to all this their knowledge was accurate and their opinions correct. Their only error consisted in the erroneous assumption and belief that Bickford and Willard were in fact the real and legal assignees of Stone. But this was a mistake in a matter of vital importance. The whole bargain, and whether there should be any bargain at all, manifestly depended upon it. For if they knew that Bickford and Willard were not the legal assignees of Stone, and consequently that the title to the estate remained in him, notwithstanding their deed to De Witt, it is impossible to suppose that he would have contracted to sell the estate, or that the plaintiff and Chamberlin would have agreed to buy it of him and pay for it the large and valuable consideration which they did. But in truth this was not known to any one of them; and they all acted in ignorance of the real fact, and in the mistaken belief that Bickford and Willard were the legally constituted assignees of Stone, and consequently that their deed had conveyed his right and title in and to the estate to De Witt. That was his understanding and his claim. He set up no pretension of his own to any right or. interest in the estate, other than the title of Stone which he believed that Bickford and Willard as his assignees had a right to convey, and which all parties assumed as a fact that he had acquired under their deed. He had no intention or thought of selling or of offering for sale anything else, and the plaintiff and Chamberlin had in view the same object and purpose which he had, and understood and believed exactly what he understood and believed concerning the *537supposed official character and authority of Bickford and Willard. But they were all misled by, and acted under, the common and mutual error and mistake into which they had fallen, and neither of them would have acted as. he did if such error and mistake had not existed. It is, therefore certain that their new bargain was made when they were all mistaken in reference to a material fact, and that this was the controlling influence which prevailed upon them to contract with each other. Of the existence of this mistake, and of its materiality and prevailing effect, there is no doubt. That there has been an entire failure of the consideration for which the money was paid is equally certain.
On the 11th of August 1858, about two weeks after the date of the deed from De Witt to her, the plaintiff executed a deed, similar in its terms to that received from him, to Tower & McGaw, and took from them their promissory notes for the entire purchase money, secured by mortgage on the estate. No part of the principal of those notes, which still remain in her hands, or of the interest which has accrued thereon, has ever been paid. And as her deed conveyed no title to her grantees, they have a perfect defence to the notes. No action can be maintained on them, nor can any part of their contents ever be recovered. Rice v. Goddard, 14 Pick. 293. Whittemore v. Waters, cited in Gates v. Winslow, 1 Mass. 65. Kerr v. Kitchen, 7 Barr, 486. Boas v. Updegrove, 5 Barr, 516. Soper v. Stevens, 14 Maine, 133. The distinction between a legal defence to such notes, and the right to recover back, upon mere failure of title, money voluntarily paid for a quitclaim deed, is particularly stated, explained and vindicated in several of the cases above cited.
Immediately after the judgment and decree in the case of Grafton Bank v. Bickford, above referred to, Stone then being insolvent, new assignees in insolvency were duly appointed, and all his estate was assigned to them. On the 1st of January 1861 these new assignees conveyed the premises which are the subject of the present controversy to Bela J. Stone. The plaintiff has never personally been in possession of the premises, but Chamberlin and Borroughs, either alone or.jointly with other *538parties holding under the deed of De Witt, have been in possession of the entire estate ever since the 28th day of July 1858, claiming title under that deed. Bela J. Stone and the new assignees have commenced suits against Chamberlin and Borroughs to recover possession of the property and the mesne rents and profits. In these suits they must necessarily prevail, since they have a good, and Chamberlin and Borroughs have no, legal title to the estate. And as the whole of the rents and profits must be accounted for, and the amount thereof paid to the true owners, it appears that nothing has been or can be realized and retained by the plaintiff, or by her grantees or assignees, for the use, occupation and improvement of the estate.
It has already been determined in another action — Earle v. Bickford, post, 549 — that Bickford and Willard are not entitled to retain the money paid to them on the execution of their deed to De Witt, but that it may be recovered back from them by De Witt, the plaintiff and Chamberlin, in the proportions which they severally contributed. If, therefore, the sum paid by the defendant has not already been or shall not hereafter be voluntarily returned and restored to him, he may maintain an action against them for its recovery.
From this reference to the facts proved upon the trial, and the conclusions directly and necessarily to be deduced from them, it appears that the plaintiff paid to the defendant the sum of $3800, in the intended execution of a contract made by the parties under and in consequence of a common and mutual mistake respecting a most material fact; that this mistake was the efficient cause of the making of the contract; that she has received no benefit whatever in return for her money, having acquired neither the estate, nor the right, title and interest of Stone therein, which it was her object and purpose to buy, and the object and purpose of the defendant to sell and convey to her ; and therefore that there has been not only a failure of title to the estate which was the subject of contract, but also an absolute and total failure of the particular and special consideration for which the money was paid. Yet the defendant now claims that he is entitled to retain and hold it as his own, although it *539has become manifest and certain that he obtained it solely in consequence of a mistake concerning a material fact, into which, without fault or negligence on either side, the parties had fallen, and by which they were equally misguided and deceived ; and although by the quitclaim deed which he made to her he neither lost nor parted with anything of his own, nor conferred any benefit or advantage upon her; in short, although he got her money, by means of a mutual and controlling error and mistake, literally for nothing. Such a claim has surely no foundation in justice or equity, and to my own mind it seems clear that it cannot in law be maintained.
But the defendant insists that as it is a well settled and established principle of law that a mere failure of title furnishes no ground for recovering back money paid upon a quitclaim deed, he has a perfect legal defence to the present action. And this would certainly result as a necessary legal consequence from that principle, if it covered the whole ground upon which the plaintiff predicates her demand and her alleged right to recover back the money which she paid to him. For although it is a general and familiar rule that money paid upon a consideration which has failed may be recovered back, that rule is not applicable to the case of a payment voluntarily made upon the execution and delivery of a quitclaim deed, where there has been neither fraud nor mistake. 1 Parsons on Con. 386. Claflin v. Godfrey, 21 Pick. 9. Boas v. Updegrove, 5 Barr, 516. And this inapplicability results chiefly from the reason that as the grantor may, if such be the understanding and intention of the parties, protect himself by insisting upon the introduction of proper covenants into the deed, the omission of all such covenants affords a conclusive presumption that the grantor intended to transfer and assign only his own right and interest, whatever they might be, if he had any, and that the grantee accepted the deed with no understanding and expectation that he should thereby acquire anything beyond that right. But it often happens that this bare possibility of right is all that the purchaser seeks to acquire, and all which is the subject of negotiation and contract; and of course, in such case, *540failure of title constitutes no failure of consideration. This is well explained in the case of Kerr v. Lucas, 1 Allen, 279, where it is said that the execution of a release of all one’s right, title and interest, in any property, real or personal, fairly made for the purpose of quieting a doubtful title, is a good consideration for the price paid, even if the release is afterwards found to be of no value, or of no use to the party obtaining it. The same general doctrine has frequently been held to apply in cases where the object of the purchaser is not to extinguish any possible adverse claim, but to obtain whatever right, title or interest the grantor may be supposed or .conjectured to have in the premises. Thus in the case of Gates v. Winslow, 1 Mass. 65, the defendant “ having some' pretensions to certain lands in Canada,” sold and conveyed his right therein for an agreed price to the plaintiff, and made to him a quitclaim deed thereof. And it was determined that the money paid could not be recovered back when it was subsequently ascertained that the grantor never had any title to the land. And this for the reason that the pretended right of the defendant, though it proved to be unreal and valueless, was the well understood and actual consideration for which the money was paid. And in illustration of this it was said by Strong, J., that the purchaser of a lottery ticket, which drew only a blank, might as well insist upon the return of the money paid for the ticket; for it was the possibility of obtaining the prize which it might draw and not the prize itself for which the purchaser paid the price for the article sold to him. So where one paid a sum of money to the owner of a vessel destined tó sail on one or more voyages as a duly commissioned privateer, upon an agreement that he should receive therefor a definite share or proportion of the prizes which might be captured, and the voyages were prevented by a termination of the war, it was held that the money so paid could not be recovered back upon the ground of failure of consideration, because the real consideration was the probability and chance of gain, of which chance he had the full benefit, although it ultimately proved to be unavailing and fruitless. Woodward v. Cowing, 13 Mass. 216. And where a sheriff sold *541on execution the right of the debtor to the premises advertised, and gave to the purchaser a quitclaim deed thereof, it was determined that the money paid for it could not be recovered back, because he sold only the debtor’s right, whatever it might prove to be, of which the purchaser assumed the risk, and consented to bear the consequences of his own estimate of it. Boas v. Updegrove, ubi supra. And where an executor sold land supposed to belong to his intestate, and gave a quitclaim deed to the purchaser, who was afterwards evicted by a person having a superior title, it was held that he could not recover back the purchase money, because he did in fact acquire the very right and title which he purchased, and which, though it was subsequently found to be ineffectual and worthless, constituted the real and a sufficient consideration for the money which he paid for it. Joyce v. Ryan, 4 Greenl. 101. The more general principle, that the rights of the parties are to be determined according to the express terms of the written contract, is affirmed in the case of Emerson v. County of Washington, 9 Greenl. 88, the court saying that it is well settled that if a grantee receives and accepts a deed without covenants of warranty, he cannot recover back the consideration, unless there was fraud. And again in Soper v. Stevens, 14 Maine, 133, which was an action to recover back money paid in consideration of a quitclaim deed, from the premises supposed to be conveyed by which the plaintiff was subsequently evicted by one having a better title, it was held that the action could not be maintained, because the money had been paid voluntarily, and also because it is a rule that where the parties have reduced their contract to writing, the written instrument is alone to be resorted to as the measure of their liabilities. The same principle was affirmed in the case of Higley v. Smith, 1 D. Chip. 409, although, upon the facts there shown there was no occasion for its application, inasmuch as it was held that the deed actually conveyed a good title to the land. It is also recognized as the established law in the case of Kerr v. Kitchen, 7 Barr, 486. And in Dorsey v. Jackman, 1 S. & R. 42, it was decided that a purchaser of real estate cannot recover back the purchase money paid for a quitclaim deed in *542case the title proves defective, unless there be fraud or warranty, or, as is stated by Brackenridge, J., unless the money has been paid by reason of a mistake and upon failure of consideration.
In no one of the cases above mentioned, which are all cited and relied upon by the defendant in support of his defence, was there any proof or allegation that any fraud or imposition had been practised upon the grantee, or that the parties acted or had been induced to make their bargain and to enter into and execute their contract under and by reason of a common and mutual mistake of fact. And they have been here briefly but particularly noticed for the sole purpose of showing that the principle upon which every one of them was decided is, in each instance, expressed in cautious and guarded terms by the court to be, simply, that money paid for a quitclaim deed cannot be recovered back merely because the grantee is subsequently evicted by another person having a superior and better title. And this principle is always to be strictly limited and confined to cases where, no external or collateral fact or circumstance which may affect the deed or invalidate the contract being shown to exist, the rights of the parties are to be settled and determined according to the terms, stipulations and covenants contained in the written instrument. But it is never to be applied as a governing rule to contracts into which one of the parties has been betrayed by fraud and imposition, or where the real purpose and design of both of them has been perverted or wholly defeated by mutual mistake of fact. Hence it is obvious that the defendant cannot avail himself of this principle in defence of the present action, because the plaintiff does not claim to be entitled to recover back the money which she paid to him, upon showing merely that he had no title to the estate described in his quitclaim deed, but upon the broader ground that in consequence of a mutual mistake concerning a material fact, by which the partiés were essentially misled, the formal contract into which they entered had no legal force, but was in all respects invalid and subject to be rescinded and abrogated by either of them at his pleasure, and that it has been in fact ?o rescinded and abrogated by the plaintiff.
*543In reference to the invalidity of contracts by reason of mistakes which have induced them, it is a general and well settled principle of law, that an act done or contract made under a mistake, or in ignorance of a material fact, one which is essential to its character and an operative and efficient cause of its execution, is voidable, and the parties may have relief against it both at law and in equity ; and this, although it has not been induced or promoted by any imposition or fraudulent practice. If a contract is made under a mutual error in regard to circumstances material to its character and its consequences, which necessarily disappoints and defeats the purpose and intention of the parties to it, it is utterly invalid ; it creates no permanent obligation and has no binding force upon either of them; for each of them may at his pleasure absolve himself from it. This proceeds from, and is a necessary consequence of, the principle that mutual consent is requisite and essential to the creation of a contract; and there is no legal contract when there is error or mistake of facts or of circumstances, going to the essence of it. Non videntur, qui errant, consentiré, is a maxim of universal application as well as of universal justice. And when a formal contract, the result of mutual mistake and misunderstanding respecting a material fact, is rescinded, as it may be by either of the parties, their relation to each other is consequently just the same as if it had never been made, and they are in all respects remitted to their original rights. 1 Story on Eq. §§ 134, 141, 142, 151. 2 Kent Com. (6th ed.) 477, 491. Spring v. Coffin, 10 Mass. 31. And in such case an action may be maintained to recover money which one of them has received, and which ex aequo et bona he ought to refund. Mowatt v. Wright, 1 Wend. 355. Union Bank v. Bank of United States, 3 Mass. 74. Lazell v. Miller, 15 Mass. 207.
This principle has very often been affirmed. It is distinctly stated and explained by the court in Mowatt v. Wright, above cited, although it was held that upon the facts proved there .was no proper occasion for its application, and the plaintiff therefore failed to maintain his action. But in the case of Martin v. McCormick, 4 Selden, 331, it was both affirmed and acted upon. *544and was the very basis and turning point of the decision of the court. The plaintiff was the owner of a tract of land which had been sold for taxes. Under a mistaken supposition of the parties that the purchaser at the tax sale had received a conveyance which had become absolute, the plaintiff bought in the title, and paid for it the price agreed upon. It was afterwards discovered that in this particular matter of fact the parties were both mistaken, and acted under that mistake; and it was held that, upon the ground of this mistake and the consequent failure of the consideration, the money paid could be recovered back. So, where the city of Troy made an assessment on certain land for the expenses of opening a street, and the tax not having been paid, the land was sold for its payment. The purchaser afterwards released all his right to the city, and the city sold the land to the plaintiff, and received payment of the price for which it was sold. All the parties acted in the belief that the tax had been duly assessed, and that the sale first made was valid, and that the deed made in pursuance of it conveyed the title. But it was afterwards discovered that the tax was illegal, and that the sale of the land made to obtain payment of it was void. And it was thereupon determined that, the parties having been mutually mistaken as to the facts upon which the validity of the sale depended, the contract might be rescinded, and the purchase money paid be recovered back, because the parties had acted under a common mistake in relation to a material fact, and the consideration had wholly failed. Gardner v. Mayor, &c. of Troy, 26 Barb. 423. And again, where money was paid upon a quitclaim deed, and no such estate as that described in the deed could be found, it was held that although there had been no fraud the money might be recovered back, for the reason that the parties were mistaken in supposing, and in acting upon the belief of, the existence of the particular estate attempted to be conveyed. D’Utricht v. Melchor, 1 Dall. 428. In the case of Shearer v. Fowler, 7 Mass. 31, it appeared that the land of the husband had been attempted to be conveyed by the deed of the wife, the grantor and grantee both acting under the erroneous belief that she had lawful authority to make the *545conveyance. But as she had no such authority and was legally incompetent to make the deed, the plaintiff recovered judgment for the amount he had paid upon receiving it. So, where one purchased the interest of the vendor in a remainder in fee expectant on an estate tail, and the tenant in tail had already suffered a recovery of which both parties were ignorant until after the conveyance had been made and an absolute bond had been given for the payment of the purchase money, the court ordered that the contract should be rescinded, and that all the interest which had been paid upon the bond should be refunded, on the ground that the parties were mistaken in supposing that the vendor had an interest in the subject matter at the time of the sale, and that the contract had therefore been made by them under a mutual mistake as to a material matter of fact. Hitchcock v. Giddings, 4 Price, 135. In the case of Bingham v. Bingham, 1 Ves. 126, the facts stated in the report show that an agreement had been made for the sale by the defendant to the plaintiff of an estate for the recovery of which an action of ejectment had been brought by the former against the latter. The deed was made and accepted, and the money paid. But it afterwards appeared from facts which then became known, that the estate in fact already belonged to and was owned by the plaintiff; and it was held that the money he had paid could be recovered back, for the reason that the parties had acted under a mutual mistake. And the master of the rolls said, that although there had been no fraud, and the defendant apprehended that he had a right, yet there was here a plain mistake, and such an one as the court was warranted in relieving against, and that it would not suffer the defendant to run away with money received in consideration of the sale of an estate to which he had no right.
That a contract so made is absolutely invalid and may be rescinded at the pleasure of either of the parties, or even also by any third person who may have an interest in the subject matter of it, the case of Williams v. Reed, 5 Pick. 480, may be referred to as a very significant authority. Pratt, the guardian of certain minors, advertised, and on the 3d day of July 1820 sold, their real estate to the defendant Reed, under a license *546from this court for that purpose, for the sum of $1528. On and before September 28tb 1822 Reed paid $955, and for the balance due upon the purchase gave his promissory notes to Pratt, who at the same time made to Reed a deed of the estate and placed it in the hands of one Pool, to be delivered to the grantee when the whole amount due on the notes shomd be paid. Reed afterwards paid $125 upon the notes; and on the 1st of April 1826 took them up and gave new ones for $787, that being the balance then due. Sometime after all these transactions it became known that Pratt had not taken the oath or filed in the probate office the bond required by the statute to qualify him to make a valid sale, and Williams, the plaintiff, being a creditor of Reed, brought an action against him and summoned Pratt as his trustee, intending thereby to attach as the property of Reed, and as a debt due to him for the recovery of which a suit might at once be instituted and maintained, all the money which he had paid to Pratt in part payment of the price he had agreed to pay for the estate. Reed had entered into possession of the land soon after the purchase, and continued thenceforward for more than six years, and up to the time of the service of the trustee process, to have the exclusive use and enjoyment of it; and neither he nor Pratt had ever rescinded, or attempted or expressed any intention or wish to rescind the contract, which they had evidently made fairly, but in the mistaken belief that Pratt had duly complied with all the requirements of law which were necessary to qualify and empower him to make a valid and effectual conveyance of the estate. Pratt prayed to be discharged, and objected that the money paid to him by Reed could not be held as his property by force of the attachment. But the court said that as there was no bond and no oath the sale was void, or at least voidable, so that the parties to it were at liberty to vacate it and consider ■it as annulled; that the estate, notwithstanding the deed of the guardian, still belonged to the minors, and that Reed had a right of action to recover back the money he had paid as a payment upon a consideration which had failed. And Pratt was thereupon charged as trustee, and thus compelled to rescind the *547contract. This, therefore, was in reality, though not expressed in those words, a direct decision that a contract entered into by parties under a mutual mistake of a material fact can have no binding force or effect in law, but must, when contested, be treated as a nullity; and that the relations of the parties to each other when it is rescinded are the same as they would have been if it had never been made.
These cases by no means comprehend all the contingencies or combinations of circumstances under which money paid upon a contract induced and entered into under a mutual and common mistake of fact may be recovered back from the vendor. They are only particular but varied instances, exemplifying the general principle which is absolute in its terms and subject to no qualification, reaching to every possible case in which parties have acted in substance and effect contrary to their own will and purpose, under the controlling influence of error and mistake. Whenever the existence and effect of such common error and mistake disappoint and frustrate their intention and the object they mean to accomplish, the prevalence of such mistake always invalidates the contract into which they have entered, and they are then to be restored, as nearly as may be, to their original rights.
The application of this just and equitable principle of law to the facts proved upon the trial of the present action would seem to leave no room for doubt as to what ought to be the result of it. The new bargain of the parties, as has already been shown, was founded upon and was induced by a mistake of fact, most material in its character and consequences, in which, without fault or blamable negligence, they equally participated, and the consideration upon which the plaintiff paid her money to the defendant has wholly failed. This gave to each of them the right, upon discovery of the error, to rescind the contract, and the demand of the plaintiff upon the defendant for the restoration of the money was a declaration of her purpose to rescind it. She thereupon became entitled to be remitted and restored to her original rights, which includes of course the restoration of the money which she had paid; and the defendant, *548having failed in consequence of their mutual mistake to transfer or assign to her any equivalent for it, and having parted with no right or interest to which he had any title or legal claim, but having by means of the mistake received the money without consideration, was bound both in law and equity to repay it at once.
And in this principle of law and the facts of the case is found a plain and decisive answer to the further position assumed by the defendant, that the stipulations in the written instrument, which is called his bond, furnish a good and sufficient consideration for the money which he received of the plaintiff. This might be correct if its stipulations had been obligatory upon him; but though supposed to be so while the parties remained in ignorance of the mistake by which they had been misled, they really were not. It was part of the new bargain for the sale and conveyance of the estate that this bond should be given, and it was made and executed as a part of that contract at the same time when the deed was delivered and the money paid. It was all one transaction. And the whole contract being invalid by reason of the mistake of fact, none of the stipulations embraced in it could have any binding force or impose a legal obligation upon either of the parties. The defendant had the right and privilege equally with the plaintiff to insist upon the rescission of the contract as soon as the error was discovered. And whenever the rescission should occur, he would at once be remitted to the rights which existed before the contract was made. He might thereupon have enforced his mortgage, by proceedings with a view to foreclosure, or by sale and conveyance under the power given him for that purpose, without incurring any liability thereby, just as the plaintiff could insist upon the refunding of the money she had paid. He was under no obligation to refrain from pursuing whatever measures he deemed essential to his own protection and the enforcement of his rights. His forbearance and delay in doing so were not required by any legal restrictions to which he was subjected, but resulted from his ignorance of the existence of that mistake which invalidated the contract of the parties, and his consequent want of knowledge of what his rights really were. By this delay it does not *549however appear that he suffered any loss. His debt continued to be well secured by mortgage upon the real estate, which was ample in value for that purpose; he was put to no inconvenience by paying or purchasing any outstanding incumbrance; and he enjoyed whatever benefit could be derived from the use of the plaintiff’s money, for which he is not called upon or bound to account, from the time when he received it, until its return was demanded. But it is immaterial whether there was loss or gain, the real question here being, what are the legal consequences resulting from the transactions of the parties. In this view it is sufficient that, as the bond was not obligatory upon the defendant on account of the mistake which invalidated the whole contract, the stipulations contained in it afforded no consideration for the money paid to him.
In conclusion I have only to add that, in view of the whole case and for the reasons stated, it appears to me that no legal or equitable defence to the action has been shown, and that the plaintiff ought therefore to have judgment for the full amount of her claim, with interest from the day when the restoration of the money was demanded.
Verdict set aside
