Upon the merits of this case the demurrer cannot be sustained. I am not aware of any case in our own courts, or in England, where the simple suppres-" sion, by the buyer, of a fact which materially enhanced -the value of the property, has been deemed sufficient to set aside the sale, on the ground of fraud. The rule is different where the purchaser applies to a court of equity to enforce the spe-. cific performance of an agreement. In such a case this court will not enforce a specific performance of the contract, if the complainant has intentionally concealed a material fact from the adverse party, the disclosure of which would *392have prevented the making of the agreement; but he will be left to his remedy at law. it .has even been questioned by many whether the suppression of a material fact by the ' one party, of which fact he knew the other' party to be ignorant, was not of itself sufficient to avoid the contract on the ground of fraud. Thus in Perkins v. M’Gavock, (Cook’s Rep. 417,) the court of errors and appeals in Tennessee say, it is a sound principle of equity that each party to' a contract is bound to disclose to the other all he knows respecting the subject matter materially affecting a correct view of it, unless ' common observation would have furnished the information. They also say thát the neglect to disclose facts within the knowledge of one party, and not of the other, would in equity be considered a concealment which is both immoral and unjust. Although our courts have not gone that length, yet, even in this state, very slight circumstances, in addition to the intentional concealment of a fact, have been considered sufficient to constitute a fraud upon the other party. Thus in Wendell v. Fosdick & Davis, (13 John. R. 325,) where the defendants had taken a deed of land which they afterwards ascertained had no actual existence, and after this they sold and assigned their interest under that deed to the plaintiff without disclosing to him that fact, he was permitted to recover against them for the fraud. So also in Monell & Weller v. Colden, (id. 395,) where the vendor of a water lot, knowing that the purchasers wanted to buy the lot for the purpose of obtaining the privilege of a wharf, represented to .them that the owners of land bounded' on the water had a right by law to apply to the commissioners of the lánd office for a grant of the privilege to build a wharf adjacent to the land, whereas he in fact knew that the lands under the water had been previously granted, the purchasers were allowed to recover for the fraud. And in a recent case before Lord Eldon, he adverts to the general principle that parties dealing for an estate have a right to put each other at arms length ; and that if the purchaser knows there is a mine upon the estate, and the vendor makes no enquiry, the former is not bound to give him information thereof. But he says “ very little is sufficient to affect the application of that principle. If a word, if ai single word, be dropped which tends to mislead the vendor, that *393principle will not be allowed to operate. ” (Turner v. Harvey, Jacob’s R. 178.) And certainly if the purchaser does any act, or makes any declaration, with the intention of misleading the seller and preventing him from ascertaining the real situation of the property, and at. the same time conceals from him a fact which he knows to be material, he is guilty of a fraudulent deception.
From the statement in the bill this case appears to be one of that description. The defendant Palmer had discovered a valuable mine on the lands of Livingston, whjch were then wild and uncultivated and lay remote from the residence of the latter. Knowing that he could not obtain the land if he discovered the fact of the existance of the mine, he does not content himself with making a bargain, in the language of Lord Eldon, at arms length ; but he falsely and fraudulently represents the the land as being of no value except for a sheep pasture, and states that he wants it for that purpose. By this deception the vendor is thrown completely off his guard, and he contracts to sell the land at the usual rate or price, of. rough broken land in that region, instead of directing his agent, near the premises, to enquire and ascertain its true value.
But I think there is an insuperable objection to the complainant’s recovering upon his bill in its present shape. Al-' though the conveyance of the land was obtained by a fraudulent misrepresentation, it was not void. It was- only voidable, at the election of the vendor. And the defendants or some of them were in the actual possession of the premises, claiming title to the same under their deed, at the time of the conveyance to the complainant. The legal title to this property could not pass to the complainant, under that conveyance, while it was thus held adversely. If John Livingston was still living he would be a necessary party to a bill to rescind the sale on the ground of fraud. Since his death, all his heirs at law, or the devisees of this particular part of his estate, are necessary parties. I lay out of question what was 1 said on the argument as to this conveyance to the complainant being in the nature of a testamentary disposition of his property, to carry into effect a previous arrangement. The *394deed of January 1820, is not set up in the bill as a devise of the estate, but as an absolute grant; neither is it stated to have been executed in due form of law as a will of real estate.- •
The demurrer must therefore be allowed, with liberty to the complainant to amend his bill by making all the heirs at law, or the devisees of John Livingston, parties thereto, on payment of costs. And if he does not amend -within' sixty days, the bill must be dismissed, with costs to the defendants.
It may be proper however to suggest that if the fact is, as stated by the defendant’s counsel, that John Livingston devised no part of this land to the complainant, but that he actually made a -will by which it was devised to other persons, under the general, description of all the residue of his estate, no amendment can help the complainant. (a) In that casé it will be necessary to dismiss the bill in this suit, and to bring a new action in the names of those to whom the legal title passed on the death of John Livingston, if they shall be advised to proceed further in this matter.
