This, was an action of replevin, brought by Peak, the plaintiff below, in the late district court for Milwaukee county, for the schooner “ Liberty,” with her anchor, chains, small boat, and all other apparel and furniture to said schooner belonging, together with the enrollment and license for said schooner “ Liberty.” The action was in the detinet, and the plea non detinet, simply. The writ was served, as appears by the sheriff’s return, by replevying the schooner, together with her furniture, tackle and apparel, and delivering the same to the plaintiff, who gave bond as the law directs.
Subsequently to the filing of the plea, and without a trial, the plaintiff filed with the clerk of the court, in vacation, a written stipulation that a judgment of discontinuance should be entered in the cause ; but the,district judge, as appears from the bill of exceptions, would not permit a judgment of *261discontinuance to be rendered upon tbe stipulation thus filed. Afterwards, however, the plaintiff, as the record shows, at a term of the court held on the second Monday of June, 1844, discontinued the suit, whereupon the defendant waived a judgment for the return of the property replevied, and elected to take his judgment for its value under the statute. This judgment was accordingly rendered, and the value of the property was thereupon assessed by a jury at the sum of $800 ; the juiy also assessed the damages for the detention of the property, and fixed the sum at $64.87. This assessment of the value of the properly, and of the damages for its detention, was set aside by the court, on motion of the plaintiff’s attorney, and a new writ of inquiry awarded. The jury, empaneled by virtue of this writ, at a subsequent term of the court assessed the damages to the defendant at six cents; upon which assessment the court rendered a judgment in favor of the defendant for the said damages and for his costs. It is very questionable whether the court was warranted in rendering any judgment upon this assessment of the jury. A judgment had been previously rendered by the court in favor of the defendant, for the value of the property replevied, and the object of the writ of inquiry was to ascertain the value of the property, as well as the damages which the defendant had sustained by reason of its detention; and yet the jury assessed the damages merely, and did not find at all in relation to the value of the property. This it was clearly their duty to do. See statute, p. 274, §§ 30, 32. They manifestly discharged them duty very imperfectly, and it is very doubtful whether the court could properly enter a judgment upon their assessment. But this is not assigned as error and has had no influence upon the court in disposing of the case.
Various exceptions were taken.by the defendant to the ruling of the judge, in relation to the admissibility and effect of the testimony introduced by the plaintiff to the jury empaneled to make the assessment. The testimony offered by the *262plaintiff and objected to by the defendant, which was admitted by the judge, tended to prove a settlement of the suit and of the controversy in regard to the schooner by the parties, and consequently a discharge of the liability of the plaintiff. The defendant contends that this was improper, as the jury had nothing to do but to assess the value of the property, and damages for its detention.
Undoubtedly, a judgment maybe discharged by the parties to it, like any other obligation, and when the discharge is proved in a proper manner, the obligation created by the judgment ceases ; but it is to be observed that the testimony in question related to a settlement of the suit previous to the time when the judgment was rendered in favor of the defendant for the value of property. This judgment entitled him to recover the value of the property, as well as damages for its detention from the plaintiff; it was in full force and not reversed, and although in its nature interlocutory, until reversed, was conclusive between the parties ; the plaintiff could not impeach it collaterally, nor rely upon transactions which took place between himself and the defendant previous to its rendition, to affect the liability created by it. It is clear, then, that this testimony, which tended to prove a settlement of the suit by the parties in the winter of 1843-4, or in the spring of the latter year, when the judgement was not rendered until June succeeding, was inadmissible. But it is said that this testimony was admissible in mitigation of damages, and was admitted on that ground by the judge. I cannot see how this affects the question. The plaintiff might have shown in mitigation of damages, that the property, after being delivered to him by the sheriff, had been re-delivered to the defendant, or that he had retaken it Dewitt v. Morris, 13 Wen. 496; Russell v. Butterfield, 21 id. 300. But this testimony (if it proved anything) directly impeached the judgment which the court had previously rendered, and could not be regarded as tending to prove any fact which could properly be regarded as mitigating *263tbe damages. Another exception to the ruling of the judge was in relation to his charge to the jury upon the effect of the testimony. He charged the jury that if they believed the testimony of the witnesses, it amounted to a release of Pede, and a satisfaction, and that the finding of the jury fixed the extent of the liability of the bail, etc. I am of the opinion that the testimony, taken together, will not bear tins construction. If it had been properly admitted — if the plaintiff could have shown in this way that the judgment which the defendant had recovered against him had been wrongfully obtained it still falls short of establishing the fact of a release of the plaintiff. The testimony introduced by the defendant shows that the plaintiff discontinued his suit with a full knowledge that the effect of the discontinuance would be a judgment against him for a return of the property, or for its value, as the defendant should elect. It is hardly credible that he should have acted in this way if there had been previously a settlement of the suit between the parties ; at least the jury should have been permitted to put such a construction upon the testimony as they should think proper.
It was said in the argument by the counsel for the defendant in error, that the defendant below was not entitled to a judgment for a return under the plea which had been put in, and he cited the case of Pierce v. Van Dyke, 6 Hill, 613, to maintain this position. 1 do not think this position well taken. By our statute concerning the action of replevin, section 19, it is provided, that “such plea shall put in issue, not only the detention of such goods and chattels, but also the properly of the plaintiff therein.” I do not understand the case relied upon to be an authority to the extent claimed. On the contrary, the judge who delivered the opinion of the court, thought that under the statute of New York (which, in this respect, is the same as ours) the jury might so find as to entitle the defendant to a judgment for the return of the properly, when the action was in detinet and the plea non detinet, merely. In *264this case there was no jury called to try the issue, but the plaintiff voluntarily gave the defendant a judgment by discontinuance, and thereby confessed all that the defendant could have proved under his plea.
Upon the whole, we are of the opinion that the judgment of the district court must be reversed. We give no opinion as tci the effect of the judgment against defendant in error, upon the sureties in the replevip. bond.
Judgment reversed.
