The issue raised by this appeal is whether a conviction which is superseded by an acquittal on appeal after a trial de novo is conclusive of the existence of probable cause in a subsequent action for malicious prosecution.
To be successful in an action for malicious prosecution the plaintiff must allege and has the burden of proving that the defendant had no probable cause for instituting the proceedings against him. Lack of probable cause is only one of the essential elements to such cause of action.
Elmer v. Chicago & N. W. R. Co.
(1950),
The respondent argues that a conviction reversed on appeal, whether heard on the record or as a trial de novo, should at the most be prima facie evidence of probable cause and in this case the conviction should be given no effect because of the nature of the trial in the district court.

The question of the effect of a conviction on the issue of probable cause was first decided by this court in
Topolewski v. Plankinton Packing Co.
(1910),
In adopting this view the court relied upon
Crescent City L. S. Co. v. Butchers’ Union S. H. Co.
(1887),
The
Topolewski Case, supra,
was followed by this court in
Bayliss v. Clayton
(1932),
The rule in Wisconsin has been adopted by the majority of jurisdictions considering this question. 34 Am. Jur., Malicious Prosecution, p. 737, sec. 55. The rule stated in Restatement, 3 Torts, p. 421, sec. 667 (1), follows: “The conviction of the accused by a magistrate or trial court although reversed by an appellate tribunal, conclusively establishes the existence of probable cause, unless the conviction was obtained by fraud, perjury, or other corrupt means.”
The respondent argues there is a distinction between the
Topolewski Case, supra,
and the facts in the instant case,
*42
especially where the original conviction was had in a police court, and cites
Hanser v. Bieber
(1917),
The pleadings did not allege collateral fraud so as to destroy the effect of the conviction on the question of probable cause. It is true the judgment in the district court of Milwaukee county has no effect so far as the conviction of the respondent is concerned, but the reversal of the conviction on appeal or the superseding of that conviction by an acquittal after a trial de novo does not destroy the fact, for the purpose of determining probable cause, that there was a conviction in the district court. In order to destroy the effect of the conviction on the issue of probable cause, the plaintiff must plead and prove in a malicious-prosecution action that the conviction was obtained by collateral fraud of the defendant.
The matters set forth in the affidavit of the respondent which collaterally attack the conviction do not amount to collateral fraud. Unless the matters relied on to attack the conviction collaterally amount to fraud and also are attributed to the complainant in the criminal action, they do not come within the exception of the rule. Here the appellant had no part in the matters relied upon by the respondent. *43 Under the court rules of the district court the respondent waived the jury trial by not demanding it. Ch. 218, Laws of 1899, as amended, 44 W. S. A., p. 129, secs. 199-10. The appellant did not prevent the respondent from calling witnesses and she was not responsible for his alleged dazed condition or lack of understanding.
The gist of the respondent’s argument is that if he had had a jury trial and counsel in the district court, he would have been acquitted as he was on his trial on appeal. This does not necessarily follow. Even if the respondent had been acquitted in the district court, such acquittal would have only been
prima facie
evidence of want of probable cause under the rule of
Bigelow v. Sickles
(1891),
The question here is not whether the respondent was guilty or not guilty of disorderly conduct, but whether the appellant had probable cause in instituting the charges against the respondent for disorderly conduct. The conviction of the respondent is evidence of the probable cause which existed at the time the appellant made the charges. This view is expressed in the rule of law based on public policy that a conviction although reversed on appeal, whether on the record or by a trial de novo, is nevertheless conclusive evidence of probable cause in the malicious-prosecution action unless such conviction was obtained through the collateral fraud of the defendant. We conclude the trial court *44 was in error in its view that the acquittal on appeal destroyed the conclusive effect of the conviction on the issue of probable cause and its order should be reversed.
By the Court.- — -The order appealed from is reversed, with directions to enter an order dismissing the complaint.
