The cause of action in these suits is the same, but the same defendants are not all joined in each of them. The declarations allege in substance, that Benjamin Glidden, jr. commenced an action against the plaintiff to recover several parcels of real estate, thát a verdict was rendered in that action in favor of Glidden, and judgment was entered on the verdict, that all of the defendants fraudulently conspired together to defeat the plaintiff’s title, and to aid Glidden in his *437suit, and that by the false testimony of two of the defendants and others, the verdict was obtained against the plaintiff.
These actions are brought to recover damages arising from the judgment obtained by Glidden against the plaintiff, and if they should be sustained, the record would present the anomaly of a judgment remaining in full force, and of another, in which damages were rendered on account of the existence of the former one. But the judgment against the plaintiff, so long as it remains in force, must be considered as true and just. He cannot be permitted to aver the falsity of that judgment, as the ground for the recovery of damages. It constitutes in itself a clear and unequivocal denial of his allegations. He says, that by the fraud and conspiracy of the defendants, he has lost the land, but the judgment imports that it was properly rendered in the ordinary course of judicial proceedings.
It is contended, that the defendants were not all parties to the judgment, and cannot avail themselves of it in this suit, and that the plaintiff is not estopped in relation to them, some of whom are neither parties or privies, to deny the validity of the judgment. That principle would be correct in reference to those, who were not parties or privies, in a controversy with them in relation to the land, for the estoppel must be mutual. But it does not apply to these cases. They are not brought for the land, but to recover damages for the loss of it, and the judgment shows that the plaintiff was not entitled to it. He grounds these actions upon the exhibition of a judgment against himself, and claims to maintain them because it was unjustly obtained. Glidden, who was a party to the suit, might avail himself of any estoppel arising from it, in a case where it should become expedient for him to do so, and could not be deprived of the benefit of it by being united with others. The plaintiff himself presents the judgment as the cause of his injury, and the basis of his claim against all of the defendants. He does not seek to pass by it, as res inter alios acta, but in substance admits it to be binding upon him, though he contends it was unjustly obtained, and alleges that his damages have been caused by it.
*438The suits are analogous to an action of conspiracy, and to an action on the case, in the nature of a conspiracy, at the common law. And in such actions, it must appear, that the plaintiff has been acquitted or discharged from the prosecution, commenced against him. 3 Black. Com. 126; Case of Conspiracy, 12 Co. 23; Saville v. Roberts, 1 Ld. Raym. 374; Pollard v. Evans, 2 Show. 50; Fisher v. Bristow, Doug. 215. But these actions have been superseded by the modern action for malicious prosecution. 1 Chit. on Plead. 136. In which action the plaintiff must show a want of probable cause as one of its essential elements.
It has been held that a conviction before a justice of the peace, having jurisdiction, is conclusive evidence of probable cause, although upon an appeal, there was an acquittal. Whitney v. Peckham, 15 Mass. 243. But exceptions have been made to this rule, where the conviction before the magistrate, was obtained by the fraudulent conduct of the prosecutor, and the accused was subsequently acquitted upon an appeal. Bent v. Place, 4 Wend. 591; Payson v. Caswell & al. 22 Maine, 226.
In Payson v. Caswell & al. the defendants were charged with a malicious prosecution, and also for a conspiracy to injure the plaintiff, by a prosecution known to them to be groundless. It is said by Whitman, C. J., that the want of probable cause is essential under either aspect of the case, and however malicious the defendants may have been, if they had probable cause for the prosecution, the policy of the law would shield them from harm, in a suit of this kind, whatever form it might have assumed.
The most satisfactory view, which can be taken of these cases, is to class them with actions for malicious prosecution, the principles of which apply to actions to recover damages, for the prosecution of civil suits, that are false and malicious. But a civil suit in such cases, is not considered false, unless' it has been defeated, or appears to have been brought for a larger sum than was known to be due, for the purpose of oppressing the defendant by attaching htá property, or arresting him when *439he would not be liable to an arrest for the sum actually due. Hargrave & Butler’s note, 297, to § 237 of Lit.; Mathews v. Dickinson, 7 Taunt. 399; Bul. N. P. 13; Savage v. Brewer, 16 Pick. 453. And the judgment in favor of Clidden, which was rendered upon a verdict of a jury, by the highest tribunal in the State, must he considered as conclusive evidence of probable cause.
The plaintiff cannot recover upon the ground alleged of false testimony given by some of the defendants. For an, action will not lie against a witness for giving false testimony/ in another case. Damport v. Sympson, Cro. Eliz. 520, Eyres v. Sedgwicke, Cro. Jac. 601.
If the judgment was obtained, as is contended, by fraud and perjury, the plaintiff has ample remedy by law. The court, which rendered the judgment, upon proof of these allegations, would be bound to grant a new trial, so that upon a further investigation, justice might be done. The witnesses, if guilty, might be indicted for perjury, and so might all those he indicted, who had unlawfully conspired together to deprive the plaintiff of his rights, .and their conviction would afford the most convincing evidence, that a review of the action should take place.
It is contended on the part of the plaintiff, that the pleas of the defendants are had. But it does not become necessary to decide that question, for the declarations being bad, judgment must be rendered against the plaintiff as the party, who committed the first error in pleading.
The declarations in both actions are adjudged bad.
