conclusive proof of probable cause, so, where the suit is based upon a civil proceeding, a judgment or decree by a court of competent jurisdiction adverse to the defendant in the proceeding is, in general, conclusive proof of probable cause, although the judgment in either class of actions was reversed in an appellate court.” Among the cases cited for this proposition was Crescent Live Stock Co. v. Butchers’ Union, 120 U. S. 141, 149. It was pointed out in that case that there is a split of authority as to whether the original conviction or judgment is conclusive proof of probable cause, or only prima facie proof, but in either view there is an exception where it can be shown that the conviction or judgment was obtained by fraud. For collections of cases dealing with the two classes of action, see 58 A.L.R.2d 1424 and 59 A.L.R. 2d 1413. The only Maryland cases cited in the Owens case were Rieger & Co. v. Knight, 128 Md. 189, 199 where it was held that a preliminary injunction, granted ex parte, was not conclusive, and Clements v. Odorless Excavating Apparatus Co., 67 Md. 461, 464. See also the dissenting opinion p. 605. The Court there held that an action for the malicious prosecution of a civil suit would lie, and that the judgment would be considered conclusive on the question of probable cause, even though reversed on appeal. It was also held that the record of a suit for infringement of a patent, brought by the appellee against a third person, was not admissible to show fraud in the case at bar. We do not read the opinion as holding, as the dissenting opinion suggests, that fraud would not destroy the conclusive effect of the judgment, but only that there was no proper showing of fraud in the proffer, as against the appellee in that case.
In any event, we think the exception is too well settled to admit of doubt. See 1 Harper & James, Law of Torts, sec. *4.5; 34 Am. Jur., Malicious Prosecution, sec. 55; 54 C.J.S., Malicious Prosecution, sec. 37. The Restatement, Torts,* sec. 667, states the rule to be: “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
