*697The opinion of the court was delivered by

In the case of Hope v. Linden Park Association, 29 Vroom 627, which was before this court upon the defendant’s writ of error, the plaintiff below had made out a case that in the opinion of the trial court entitled it to recover from Hope $5,000, voluntarily paid to him by the plaintiff. A nonsuit having been refused, Hope offered to prove, and in fact did prove, subject to the decision of the trial judge, who heard the cause without a jury, that the $5,000 was paid to him upon a corrupt agreement to influence the votes of members of a township committee.. The trial court overruled this defence and declined to receive this testimony, upon the ground that a defendant could not “set up Iris own corrupt action as a legal defence.” Upon the writ of error brought by Hope this court reversed the judgment rendered for the plaintiff in the trial court, upon the ground “that the policy which constrains the court to deny all relief to the parties demands that when either of those parties shall offer to show that the cause of action springs from an illegal or corrupt agreement the court shall admit and consider the legal proofs offered to that end.”

In the case of Wyckoff v. Weaver, 37 Vroom 648, the plaintiff had recovered a judgment upon a contract, the consideration of which, as shown by uncontradicted testimony, was fraudulent and repugnant to public policy. Hpon the defendant’s writ of error this judgment was reversed.

The ground of the court’s action in each of these cases, as stated by Chief Justice Gummere in the case last cited, is that “the courts of this state have steadfastly refused tó lend their aid to enforce contracts which are directed to the accomplishment of fraudulent purposes, or to entertain suits to recover damages for a breach thereof, and this they do, not out of regard for the defendant in such an action, but ^because of their unwillingness to use the powers which were granted to them for the furtherance of lawful ends in aiding schemes ivhich are in their nature venal. Since the fraudu*698lent character of the contract sued upon was conclusively made to appear by the testimony, the court below should have refused to permit the trial of the cause to proceed further and have directed a nonsuit to be entered.”

Between these two cases there is no essential difference in principle. The distinction between them is that in the one the corrupt nature of the transaction was brought to the attention of the trial court by the defendant’s offer to prove facts from which its illicit character appeared, whereas in the other the corrupt nature of the arrangement that led to the contract the court was asked to enforce appeared from testimony that was admitted and not contradicted.

In the case before us, the feature reprobated by these two decisions was presented in each of these aspects — first, by the overruling of the questions put to the defendant; and secondly, by the uncontradieted testimony of the defendant. The circumstance that the. examination that was interdicted and that the testimony that was admitted were both intended to make out a defence of fraud practiced upon the defendant does not militate against the application of the doctrine of the cited cases. The doctrine is one that concerns the court rather than the parties, and is applied by it for the protection of its proper functions, regardless of the purpose for which the court is apprised of the uses to which it is being put. The error of the court below in overruling the questions put to the defendant is not now material, in view of the uncontradicted testimony that was afterward given. By that testimony it was made to appear that the agreement that the court was asked .to enforce had been fraudulently contrived by the plaintiffs to deceive outsiders by a pretence that Johnson had gone into the enterprise, whereas his participation was only as the agent of the plaintiffs in the perpetration of this fraud. At the close of the case, there being no contradiction of the testimony, the court, of its own motion, should have directed that a nonsuit be entered.

The judgment of the Supreme Court is reversed.
