The action is for damages ensuing from a collision on a public highway between an automobile owned by defendant Frank Antonucci and operated by his son and co-defendant, Thomas, and a motor bus owned by plaintiff but leased.to Hudson Transit Lines, Inc., and in the latter’s exclusive possession and control by its servant and agent at the time of the mishap. Frank Antonucci counter-claimed for the damages to his vehicle. There was a jury verdict for plaintiff and judgment thereon; and defendant’s sole ground of appeal is that there was error in the denial of their prayer for leave to interpose a supplemental answer pleading in bar a judgment in favor of Frank Antonucci in an action for the damage to his automobile which had been made the subject of the counter-claim herein brought by him against plaintiff’s lessee, Hudson Transit Lines, Inc., in the District Court of the Essex County Judicial District after the commencement of the instant action. The later action was the first to be tried. The plaintiff herein was not a party to that action.
It is said, in a word, that “privity is a concomitant of the lessor-lessee relationship,” and thus the “controversy” in the case at hand “was between the same parties and their privies and involved the same issue,” and therefore the judgment of the District Court is res judicata of all the issues raised in this action.
There is privity of estate or interest between the lessor and the lessee of personal property; but the doctrine of res judicata does not for that reason serve to bar plaintiff’s action. Privity is simply mutual or successive relationship to the same rights of property. Privity within the view of the rule of res judicata ordinarily means identity of interest, through succession to the same rights of property involved in the prior litigation. Compare Ludy v. Larsen, 78 N. J. Eq. 237; Bigelow v. Old Dominion Copper Mining and Smelting Co., 225 U. S. 111; 32 S. Ct. 641; 56 L. Ed. 1009; Litchfield, v. Goodnow, 123 U. S. 549; 8 S. Ct. 210; 31 L. Ed. 199.
The judgment of a court of competent jurisdiction on a question of law or fact, or on a question of mixed law and fact, once litigated and determined, is, so long as it stands unreversed, conclusive upon the parties and their privies,
