FOLLETT, J.
Before the Codes, material facts occurring after issue joined could be interposed by way of defense—mere matter of resistance to the plaintiff’s cause of action—in an action at law, by a plea puis dorien continuance, (Grab. Pr. 296,) or, in a suit in equity, by a sup*265plemental answer or by a cross bill. 2 Barb. Ch. Pr. 255; Story, Eq. PL § 903. Section 544 of the Code of Civil Procedure provides that the court may permit a party “to make a supplemental complaint, answer, or reply alleging material facts, of which he was ignorant when it [his original pleading] was made.” The power of the court to permit the defendant to plead as a defense acts of adultery committed by the plaintiff since the action was begun cannot be doubted. Can such acts be pleaded as a counterclaim? It will be observed that the section of the Code above referred to does not limit the use of facts interposed by a supplemental answer to the establishment of a defense to the plaintiff’s alleged cause of action. In an action for a divorce the defendant may plead the adultery of the plaintiff as a defense and as a counterclaim ; and if proved, the defendant being innocent, a divorce may be denied the former, and granted the latter. Code Civil Proc. § 1770. The right being given to the defendant to plead and prove the adultery of the plaintiff, though committed subsequent to the commencement of the action, it is difficult to see any good reason - for denying the defendant affirmative relief. The defendant having been found innocent, and the plaintiff guilty, of the matrimonial offense, why should the judicially established facts be available only as a defense, when, by granting complete relief, justice is done in one action, and the delay, expense, and scandal of a second suit avoided? Public policy, the interests of society and of the litigants, alike demand that the rights of the parties should be determined in a single action, unless by so doing some statute or rule of procedure settled by reported cases is violated. No statute has been cited, nor have we been able to find one, which prohibits the granting of such relief. The precise question involved in the case at bar could not have arisen in this state before the Code of 1848, because our court of chancery never assumed the power to grant the innocent defendant a divorce for the adultery of the plaintiff, no matter whether it was committed before or after suit brought. Such relief was - only attainable by an original or by a cross bill. In Milner v. Milner, 2 Edw. Ch. 114, the application of the plaintiff for leave to file a supplemental bill alleging acts of adultery by the defendant after the filing of the original bill was denied. This case was followed in Morange v. Morange, 2 N. Y. Law Bul. 30. In Smith v. Smith, 4 Paige, 432, it was held that, in case a plaintiff committed adultery after suit brought for a divorce, leave should be granted the defendant to set up the fact as a defense by a supplemental answer or by a cross bill. This case was followed in Strong v. Strong, 3 Rob. (N. Y.) 669, 28 How. Pr. 432. When the last case was decided it was a disputed question whether, under the old Code, affirmative relief could be granted in such an action to a defendant, (J. W. B. v. F. D. B., 11 N. Y. Leg. Obs. 350; Anon., 17 Abb. Pr. 48; Leslie v. Leslie, 11 Abb. Pr. [N. S.] 311; Fullmer v. Fullmer, 6 N. Y. Wkly. Dig. 22, 42; R. F. H. v. S. H., 40 Barb. 9,) and the report of the case does not show whether the fact was allowed *266as a counterclaim as well as a defense. In Cornwall v. Cornwall, 30 Hun, 573, which was an action for a limited divorce, the plaintiff was granted leave to file a supplemental complaint alleging acts of cruelty committed after the commencement of the action, but it was intimated that the subsequent acts were proper in characterization of the earlier acts. This case is in harmony with the decisions in some of the states which hold that acts of adultery committed, after suit brought by the defendant, with the person charged in the original pleading as a parti ceps criminis, may be pleaded and proved for the purpose of characterizing their previous relations. Browne, Div. & Alim. 53. See, also, Borham v. Borham, 2 Prob. & Div. 193. The question now before the court was not decided in any of the cases cited, nor were the questions discussed in them nearly related to the point involved in the case at bar, but they are the only decisions found in the Reports of this state which throw light on this controversy; and, there being no statute or decision in the way, we are of the opinion that, under the Code of Procedure, adulteries committed by a plaintiff after suit brought may be pleaded, by leave of the court, both as a counterclaim and as a deiense. The ecclesiastical courts of England gave affirmative relief to defendants, (2 Bish. Mar., Div. & Sep. § 559,) and, when acts of adultery were committed by either party subsequent to the commencement of thé action, they could be alleged by a supplemental bill or answer, and, if proved, were given the same force as though alleged in the original pleading, (Barrett v. Barrett, 1 Hagg. Ecc. 22; Webb v. Webb, Id. 349; Middleton v. Middleton, 2 Hagg. Ecc. Supp. 134; Brisco v. Brisco, 2 Addams, Ecc. 259.) In New Hampshire a supplemental complaint may be filed, alleging acts of adultery committed after suit brought, which, if established, are a ground for a divorce. Adams v. Adams, 20 N. H. 299. In Kentucky, grounds for a divorce a mensa et thora, and for alimony, not existing when the original bill was filed, may be alleged in a supplemental bill, and, if proved, will support a decree. Butler v. Butler, 4 Litt. (Ky.) 202; Logan v. Logan, 2 B. Mon. 142-148; McCrocklin v. McCrocklin, Id. 370. Without attempting to reconcile Wheelock v. Lee, 74 N. Y. 495, and Mackellar v. Rogers, 109 N. Y. 468, 17 N. E. Rep. 350, or to distinguish them from th.e case at bar, we think that the fact that both parties noticed the action for trial at a special term did not deprive the court of power to permit a supplemental answer to be served. All of the issues involved in the action, including those joined by the original and supplemental pleadings, must, be tried before a jury, unless both parties waive such a trial. Part of the issues should not be tried before the court Avithout a jury, and the remainder before the court Avith a jury. There is nothing in the record which would justify this court in holding contrary to the decision of the special term, that the motion was not made in bad faith, and for the purpose of delay. When the order was granted the case had been pending but six months, and it does not appear that the defendant was negligent in not moving at an earlier date. The order should be affirmed, with $10 costs and printing disbursements. All concur.
