Upon the hearing in this eourt the appellant and defendant in error contends (1) that there was no error in the judgment of the justice, and that the county court should have affirmed the same; and (2) that the county court erred in ordering a writ of restitution in favor of the plaintiff in error, even though the county court was right in reversing the judgment of the justice.
*194The contention, of the respondent upon this appeal is that, upon the filing of his answer in the justice’s court and tendering his bond as above set forth, the justice lost all jurisdiction to try the action, and consequently his subsequent proceedings and judgment were void and were properly reversed by the county court. He also insists that there was no error committed by the county court in ordering restitution of the premises to the plaintiff in error, who had been ousted by the judgment of the justice.
We are very clearly of the opinion that the answer filed by the plaintiff in error in the justice's court, so far as it attempted to set up an adverse title to the lands in question as against the plaintiff in said action, was no defense to the proceedings to dispossess him, and as a plea of title it was not an admissible plea in said action; and that, so far as the answer sets up facts showing that the claimed foreclosure sale had not been legally made, it was a good answer to the complaint, and the justice’s court had jurisdiction to try the issues raised by such part of the answer, and the tender of the bond as on a plea of title under the provisions of sec. 3620, R. S., did not oust the justice of his jurisdiction to try the action. See cases cited below.
It has been repeatedly held by this court that, under the statute of “forcible entry and unlawful detainer,” the question of title to the premises does not arise, and cannot be put in issue by the pleadings. Where the proceeding is for a forcible entry or for a forcible detainer, it is the nature of the entry or detainer which constitutes a cause of action, and not the nature of the title which the respective parties have in the premises. Bracken v. Preston, 1 Pin. 365; _Eastman v. White, 3 Pin. 180; Cox v. Groshong, 1 Pin. 307; Ferrell v. Lamar, 1 Wis. 8; Gates v. Winslow, 1 Wis. 650; Jarvis v. Hamilton, 19 Wis. 187; Ainsworth v. Barry, 35 Wis. 136; Steinlein v. Halstead, 42 Wis. 422; Carter v. Van Dorn, 36 Wis. 289. And in cases under those provisions of the *195chapter which authorize a landlord to dispossess his tenant under proceedings similar to those for the dispossession of a person who has forcibly entered upon the possession of another or forcibly detains such possession from him, the only questions to be tried are — (1) whether the relation of landlord and tenant exists between the plaintiff and defendant; (2) whether such tenant holds over after the term of his lease has expired, or after he has violated some provision thereof, or, if the proceeding is taken for the nonpayment of rent according to his lease, whether such rent is in part unpaid; and (3) whether the proper notice has been given before the action is commenced. All these questions the justice has power to try. See Jarvis v. Hamilton, 16 Wis. 574; People v. Godfrey, 1 Hall, 240; Savage v. Carney, 8 Wis. 162; Winterfield v. Stauss, 24 Wis. 394; Ragan v. Simpson, Wis. 355; Ela v. Bankes, 32 Wis. 635; Strain v. Gardner, 61 Wis. 174.
The provision of law under which this action was commenced is new, and was first enacted as a part of ch. 145, R. S. 1878, and was clearly not intended to permit a justice of the peace to try a pure question as to the title of real estate, nor to authorize a defendant in such action to set up an adverse title as a defense to the action. If he has such adverse title the plaintiff will be unable to make out his cause of action. Ragan v. Simpson, 27 Wis. 355. In order to recover in such proceeding where the answer properly denies the allegations of the complaint, the plaintiff must prove — (1) that there was a mortgage on the premises which was executed by the defendant, or some other person under whom the defendant claims by title subsequent to the date of recording such mortgage; and (2) that such mortgaged property has been duly sold upon the foreclosure of such mortgage under the provisions of ch. 152, R. S., and that the title under such foreclosure has been duly perfected in the plaintiff. The enactment of these provisions *196of law, and conferring tbe power npon a justice’s court to entertain an action to try the rights of the parties in such case, clearly confers upon the court power to try the questions which may be raised by the pleadings in such action. It is not to be presumed that the legislature intended that a justice’s court could entertain and try a case of this kind only when the defendant admitted all the allegations necessary to be made by the plaintiff in his complaint to sustain his action; and that when the defendant denied any of the material allegations of the complaint, it would raise an issue of title which such court could not try. The very fact that a plaintiff is compelled to bring such an action is evidence that the defendant contests his right to the possession sought by him.
The power of the justice’s court to try all the issues which may be raised upon the material allegations .of the plaintiff’s complaint in this proceeding is, we think, very clear. See cases above cited. If it be not so, then the act is worse than useless, and it was a piece of folly to enact it.
If the first part of the defendant’s answer filed in the action simply means that he is not in under the mortgagor whose mortgage had been foreclosed, then it was a good defense to the plaintiff’s action; and so far as it raised any question of title, it was triable by the court, because the plaintiff can only recover upon proof that the defendant is either the mortgagor or claims under him. See Ragan v. Simpson, supra.
In a case of landlord and tenant this court held that when an assignee of the lessor brought an action under this statute, the justice necessarily had the power to try all questions relating to the assignment or assignments under which the plaintiff claimed, even though such proofs required the production of deeds or other conveyances from the original landlord. See Savage v. Carney, 8 Wis. 162; Winterfield v. Stauss, 24 Wis. 394, 398.
*197Ve think tbe justice bad jurisdiction of tbe action, and properly proceeded to try tbe case, notwithstanding tbe defendant’s answer and tender of bis bond under tbe provisions of sec. 3620, E. S.; and that being so, tbe county court erred in reversing tbe judgment upon tbe writ of certiora/ri.
"We are also of tbe opinion that tbe court erred in awarding a writ of restitution as a part of its judgment; and that this would have been error even though tbe judgment reversing tbe justice’s judgment bad been properly entered. It has been repeatedly held by this court that upon a common-law writ of certiorari, issued by an appellate court to review a judgment of a justice’s court, tbe appellate court can only review tbe jurisdiction of tbe justice’s court to render the judgment. No other questions are involved. Tbe evidence in tbe court below is not considered, nor any rulings of tbe court on tbe trial; and as a result of this rule, the only judgment which tbe appellate court can render in such case is a judgment reversing or affirming tbe judgment of tbe justice’s court. No judgment affecting tbe rights of tbe parties as to tbe matter of the controversy is determined by tbe appellate court. Healy v. Kneeland, 40 Wis. 497; Bandlow v. Thieme, 53 Wis. 57; Smith v. Bahr, 62 Wis. 244; Starkweather v. Sawyer, 63 Wis. 297.
Tbe impropriety of rendering a judgment for a restitution of tbe premises in this case, where tbe court has none of tbe evidence before it, and therefore is unable to tell whether, in justice and right, tbe possession ought to be restored to tbe plaintiff in error, is shown by tbe decision of this court in tbe case of Towle v. Smith, 27 Wis. 268. In that case, upon an appeal from the judgment of tbe justice in a proceeding for forcible entry and detainer, tbe judgment of tbe justice was reversed, and yet tbe court refused to remove tbe party who was put in' possession by tbe judgment of that court, because, from tbe evidence in tbe *198case, it would be inequitable to do so. The cases cited by the learned counsel for the respondent to sustain this part of the judgment of the justice are from states where the law upon the subject is very different from the law in this state. In New York the review of the proceedings of the justice’s court is expressly given by statute, and brings up all the proceedings and evidence in the case; and, presumably, it is the same in Massachusetts. In this state the law expressly gives an appeal from the judgment of the justice, and upon such appeal a new trial is had in the appellate court, where the rights of the parties can be determined upon hearing the evidence of the parties. If a party does not desire a new trial in the appellate court, he may, under the laws and constitution of this state, have the proceedings reviewed upon a coipmon-law writ of certiorari, but in that case the only question for review is the jurisdiction of the court to render any judgment in the case. In this proceeding the lights of the parties, as between themselves, are not considered by the court, and no judgment affecting such rights ought to be pronounced by the appellate court.
By the Court.— The judgment of the .county court is reversed, and the cause is remanded with directions to the county court to affirm the judgment of the justice.
