Whether or not a party to a written instrument may go back of it to show that the consideration on which it rests is illegal, forms a subject on which the decisions of courts are far from uniform. The maxim nemo allegans twrpitudinem suam audiendus, while regarded as inflexible between the parties, is nevertheless made to yield to the interests of public policy, and the duty of preventing the accomplishment of fraudulent and illegal designs. The test prescribed by some courts is, whether the plaintiff requires the aid of this illegal transaction to establish his case (Swan v. Scott, 11 S. & R. 164), and that, if he does not, the defendant cannot set up his own iniquity as a defense. Stewart v. Cramer, 6 Watts, 453. On the other hand, it is contended that the law ought not to interfere to further the ends of the guilty; that, if the contract is executed, it will not be enforced. Smith v. Hubbs, 1 Fairf. 71; Nellis v. Clark, 20 Wend. 24. Courts should be slow to help parties out of the mire who have voluntarily thrown themselves into it, or aid them to reap the wages of iniquity, when their enrichment would be at the expense of public morals. And this aid would be furnished if, after the law has pronounced a deed or contract void, the courts should withhold the power to take advantage of the invalidity, and *505show in what it consists. We are, therefore, of the opinion that the admission of the evidence, showing the character of the consideration on which this note was founded, was entirely proper. In Holman v. Johnson, Cowp. 343, Lord Mansfield said: “ The objection that a contract is immoral or illegal, as between plaintiff and defendant, sounds, at all times, very ill in the mouth of the defendant. It is not for his sake, however, that the objection is ever allowed; but it is founded in general principles- of policy, which the defendant has the advantage of, contrary to real justice as between him and the plaintiff, by accident, if I may so say. The principle of public policy is this, Ex dolo malo non oritur actio. No court will lend its aid to a man upon an immoral or illegal act. If, from the plaintiff’s own stating, or otherwise, the cause of action appears to arise ex turpi causa, or the transgression of a positive law of this country, then the court says he has no right to be assisted.' It is upon this ground the court goes, not for the sake of the defendant, but because they will not lend their aid to such a plaintiff. So if the plaintiff and defendant were to change sides, and the defendant were to bring his action against the plaintiff, the latter would then have advantage of it, for when both are equally in fault potior est conditio defendentis. Another learned writer, speaking to the same subject, says: “When an illegal contract or transaction cannot be enforced or allowed to stand without producing the evil which the law designs to prevent, the illegality may be pleaded or given in evidence as a bar to a suit brought to enforce the contract. For, under these circumstances, the welfare of society and the vindication of the laws are the chief objects, and the rights of parties but of secondary importance.” Collins v. Blantern, Smith’s Leading Cases, vol. 1, p. 700. These remarks clearly show the principle upon which the rule rests and commend its soundness to our approval. Does this case fall under the ban of the common law ? We might answer that any case does, whose features are contrary to good morals, or the principle of which tends to corrupt or contaminate by improper influen*506ces the integrity of our social or political institutions. From the evidence, it appears that one Griffin had filed in the land office a .caveat against the issuance of a patent to Macon, setting up that the latter had never been in possession of the land, and that his application for a patent was fraudulent and in violation of the law. It further appears that Hoyt, in consideration that Macon would execute this note and pay him the amount of money expressed in it, would procure Griffin to abandon the prosecution of the caveat, and relinquish to Macon the possession of the land, which Macon was seeking to have patented.
Pursuant to this agreement the note was executed, the proceedings on the caveat abandoned, and the land relin quished by Griffin. It is not difficult to perceive that this transaction was immoral and illegal. It was enabling Macon to procure this land through fraud and by an open violation of the law, which required him to reside on and improve the land. When the design is illegal, the law interferes and says : You shall not stipulate for iniquity, and the courts must drop the parties where it finds them. When Hoyt induced Griffin to abandon the contest, he put it in the power of Macon to perpetrate a fraud on the government, and now he cannot be heard when he claims the wages of his prostitution and depravity. It is claimed by the plaintiff in error that it is not shown that Macon was attempting to obtain the land illegally; that no presumptions as to illegal conduct on the part of Macon can be indulged,- and that, before the note can be regarded as void, it must affirmatively appear that Macon was intent on the commission of an illegal act. When one charges another with the commission of a crime, or a violation of the law, and the latter performs an act having directly in view the stifling of the investigation or the withdrawal of the proceedings instituted for the purpose of determining the existence of the offense, this act must be regarded as an admission, on the part of the person doing the act, of the existence of certain grounds for the charge, and in such case the court will place the estimate 'upon the conduct of the parties that they themselves have placed upon *507it. Brown v. Burk, 28 Vt. 312; Gardener v. Maxcey, 9 B. Monr. 93; Coppock v. Bower, 4 Mees. & Wels. 365.
If this were not true, courts would' present the strange spectacle of trying a person for a misdemeanor or felony whenever it became necessary to show that a note sued on was given in composition of a crime, or to suppress a prosecution.
When Hoyt charged Macon with having made a fraudulent entry of the land, through perjury committed by him, and Macon executed the note to avoid an investigation then pending, and threatened to be pressed, he thereby indicated that there was something wrong in his proceedings which required to be covered up.
We think the case at bar is analogous to those cases where notes have been executed to suppress proceedings in courts of justice. A contract, the basis and purport of which is to secure title to land in a manner inhibited by an act of congress, and through the agency of perjury, and to which object the payee contributed by a suppression of the truth, has a tendency to debauch both private and public morals, and cannot receive the sanction of a court.
It cannot be said that this contract involved the compromise of a doubtful right which Griffin might have had to the land. The moving, paramount consideration was the suppression of the investigation of the charges which Hoyt was making, namely: that Macon was attempting to obtain title by perjury and fraud.
It is claimed, however, that the consideration of the note is divisible, and that, inasmuch as Griffin relinquished to Macon the improvements he had made on the land, this relinquishment was a good consideration, and that the action could be sustained. It might be sufficient to say that no evidence was offered showing that the improvements were separately valued, or the price fixed upon them, and the case as it is presented does not fall within the rule laid down in Carleton v. Wood, 28 N. H. 290, where the goods sold were valued separately from the liquors. In that case, however, the recovery was had on the common counts and *508the note ruled out. See also Ladd v. Dillingham, 34 Me. 306. In Robinson v. Bland, 2 Barr, 1071, 1082, the action was on a bill of exchange for $672, of which $300 was for money lent, and $372 for money won at play, and the action was sustained on the common count, and not on the bill. But it will be perceived that the amount.of money lent was ascertained, and the good consideration readily distinguished from the bad. We admit that there are cases where recoveries have been sustained for the original consideration, although connected with illegal or forbidden transactions; but they are cases wherein the plaintiff was not considered a wrong-doer, or was the victim of the defendant, so that a denial of relief would be an encouragement to the wrong-doer, and thus the law be made to work its own defeat. Lange v. Work, 2 Ohio St. 526; Saratoga County Bank v. King, 44 N. Y. 91.
Mr. Justice Washington in Toler v. Armstrong, 4 Wash. C. C. R. 299, says:
“I understand the rule as now clearly settled to be, that where the contract grows immediately out of, and is connected with, an illegal or immoral act, a court of justice will not lend its aid to enforce it, and if the contract be in part only connected with the illegal transaction, and growing immediately out of it, though it be in fact a new contract, it is equally tainted by it.” This same case is reported in 11 Wheat. 258, and Marshall, O. J., lays down the rule to be, that if the illegal act is not the consideration of the contract, and is entirely disconnected from it, the contract is valid, though the occasion for making the contract arose out of the existence of the illegal act. In the case at bar, the abandonment of the caveat and the relinquishment of the improvements on the land by Griffin constitute one transaction, and are in furtherance of one common design, pursued by Hoyt and Macon, namely, to enable the latter to fraudulently obtain the patent, and acquire the title to the property. Such being the case, we think the entire consideration on which the note rests is tainted. We have said this much as to the merits of the case, notwithstanding no *509reference to the evidence lias been made in the assignment of errors. We decline to consider the instructions, for the reason that the entire charge is embraced in a single assignment. In Westcott v. Bock, decided at the last term of this court, we used this language : “A charge is made up of a series of propositions interdependent in one sense, yet distinct in another. Some may be correct, others wrong. Where a party assigns error to an entire charge, we think each proposition announced by the court should be regarded as a separate instruction and should be specifically assigned. It is well settled that, if a series of propositions be embodied in instructions, and the instructions are excepted to in a mass, if any one of the propositions be correct, the exception must be overruled.” Johnston v. Jones, 1 Black, 220.
