There is some conflict of authority as to the competency of evidence of the reputation of the plaintiff in a trial of an action for malicious prosecution. There are many cases in which it is held that in actions of this kind, as in actions of slander, the general bad reputation of the plaintiff may be shown in mitigation of damages. There are also decisions, that in suits for malicious prosecution such reputation may be shown to meet the allegation of want of probable cause. Bacon *548v. Towne, 4 Cush. 217, 241. Pullen v. Glidden, 68 Maine, 559. Barron v. Mason, 31 Vt. 189. Rodriguez v. Tadmire, 2 Esp. 721. Gregory v. Thomas, 2 Bibb, 286. Bostick v. Rutherford, 4 Hawks, 83. Gregory v. Chambers, 78 Mo. 294. Rosenkrans v. Barker, 115 Ill. 331. But cases do not go so far as to permit proof of particular instances of bad conduct.
In determining whether there is probable cause for a prosecution for the commission of a crime, the known character or general reputation of the person suspected is always an element of some importance; for, as was said by Chief Justice Shaw in Bacon v. Towne, ubi supra, “ The same facts, which would raise a strong suspicion in the mind of a cautious and reasonable man, against a person of notoriously bad character for honesty and integrity, would make a slighter impression if they tended to throw a charge of guilt upon a man of good reputation.” In a suit of this kind, where the prosecution complained of was for an offence implying moral turpitude, the plaintiff’s general reputation at the time of the prosecution, if the defendant was where he would be likely to know it, is always involved in the issue, and the defendant may properly be permitted to show that it was bad.
We see no good reason why the plaintiff should not be permitted, on the other hand, to show affirmatively that it was good. It is true that every one is presumed to be of good character until the contrary appears, and this presumption ordinarily saves the necessity of proof. Indeed, in civil eases, as a general rule, evidence of reputation is not competent upon a question as to liability for a particular act. But whenever character is in issue, the rule is different. One charged with a crime is not obliged to rest upon a presumption of good character. In favorem libertatis, he may prove the fact, if he can, by a weight of evidence far more effective than any mere presumption. A plaintiff in a suit for a malicious prosecution upon a criminal charge has the burden of proving that the prosecution was without probable cause. In defending against the prosecution he would have had the right to show his good reputation, although his character was not attacked otherwise than incidentally by the prosecution itself. The same incidental attack upon his character necessarily appears in the suit *549for the malicious prosecution. To prove.that the attack was originally made without probable cause, we think he should be permitted to show his good reputation known to the defendant when the prosecution was commenced. In several of the States there are adjudications to this effect. Woodworth v. Mills, 61 Wis. 44. Blizzard v. Hays, 46 Ind. 166. Israel v. Brooks, 23 Ill. 575. Miller v. Brown, 3 Mo. 127. Scott v. Fletcher, 1 Overton, (Tenn.) 488. The defendant’s exception to the admission of this kind of evidence must be overruled.
Testimony of statements by Madden and Hewett to the justice who issued the warrant, made in the absence of the defendant, was rightly excluded. The statements cannot be treated as facts tending to show the plaintiff’s guilt, and competent as evidence for that purpose, which the defendant may be presumed to have known, even though his knowledge of them is not distinctly shown. See Bacon v. Towne, 4 Cush. 217, 241. They are mere declarations of third persons, which do not appear to have been communicated to the defendant, and which have no bearing upon either of the questions at issue in the case.
The third exception presents a question of more difficulty. To show that the prosecution was not without probable cause, the defendant relied upon a statement of Mrs. Madden, communicated to him by her husband, that she, accompanied by the plaintiff and another, broke into the defendant’s premises, and stole his wine. It became a question for the jury to determine how far the defendant was warranted in believing her statement, and how far he did in fact believe it. It is quite clear that it would not be competent to attack the credibility of a witness in a trial by proving that he had been confined in jail, or that he had been guilty of any unlawful or criminal act. Hothing less than proof of conviction of a crime would be admissible. But this rule rests upon considerations of public policy, which forbid the introduction of evidence of particular acts, involving a trial of new and unexpected issues, for which the opposing party could not be expected to be prepared. There can be no doubt that one’s known acts of misconduct, indicating his character, may properly be considered in determining his credibility.
*550A witness was permitted to testify that the defendant, before the complaint was made, said “ that he had heard that Mrs. Madden had been in Dedham jail.” If that statement tended to show, as against the defendant, that she was less credible than other persons, it was competent evidence upon the question whether there was probable cause for the prosecution. If it had no proper bearing upon her credibility, but at the same time indicated distrust of her on the part of the defendant, it was competent on the question whether the prosecution was malicious. It may be argued, with much force, that one who should say colloquially of another that he had been in jail, would probably mean that he had been there under such circumstances as to affect his reputation, and to indicate that he was untrustworthy. So, to say of another that one has heard that he has been in jail, implies some degree of credence in the story. The evidence in the present case seems to have been of little importance. Yet it purported to show what was in the defendant’s thoughts before the complaint was made. Upon the facts disclosed, we cannot say that the jury might not properly consider it. Exceptions overruled.
