Urner, J.,

delivered the opinion of the Court.

This suit was brought by the appellee against the appellant corporation, in the Court of Common Pleas of Baltimore City, to recover for personal injuries sustained in a collision between the appellee’s automobile and that of the appellant, which is alleged to have occurred because of the negligent operation of -the appellant’s car. The declaration claimed damages to the amount of $5,000. Subsequently' the appellant brought suit against the appellee in the Peoples’ Court of Baltimore City to recover’ for the damage to the appellant’s automobile in the same accident. It was the theory of the second suit that the collision was caused by the appellee’s negligence. The amount of damages claimed by the appellant was $94. There was an early trial of that case, resulting in a judgment for the appellant for the sum of $44.10 and costs, from which the appellee took an appeal to the Baltimore City Court, where a similar judgment, on the verdict of a jury, was rendered. After that final disposition of its suit the appellant filed pleas of res adjudicaba to the appellee’s prior and pending action. The principal question, on this appeal from a judgment for the appellee, is whether the judgment on the appeal from the Peoples’ Court to the Baltimore City Court, in the appellant’s suit against *259 the appellee, is conclusive of the issue involved in the present litigation.

At the trial of this suit in the Snperior Court of Baltimore City, to which it had been removed from the Court of Common Pleas, parol evidence was admitted to1 the effect that, in the trial of the other suit in the Baltimore City Court, the appellee, as defendant in that case, was not allowed to offer evidence because of the pendency of his suit in the Court of Common Pleas There was no contradiction of that testimony. The record of the docket entries and pleadings in the appellant’s suit shows that it related to the same accident as the one to which the pending action refers, but according to the undisputed proof the defense there attempted to be interposed was excluded because it was the basis of the recovery sought in this separate suit, which had been previously instituted and was then awaiting trial. It is conceded that the evidence offered in this ease, while contradicted, was legally sufficient to prove that the appellant’s negligence was responsible for the accident in which the appellee was injured, and to support the verdict for the ap*pellee, which was for the sum of $152.

One of the essential conditions for the application of the principle of res adjudicata is that the issue, in the trial of which it is invoked, must have been determined on the merits by the former judgment which is pleaded as a defense. Elkton v. Sweet, 141 Md. 614; Wiley v. McComas, 137 Md. 637; Christopher v. Sisk, 133 Md. 48; Impervious Products Company v. Gray, 127 Md. 64; Feldmeyer v. Werntz, 119 Md. 285. It would hardly be just to bold that the merits of the appellee’s claim, urged in this case, were conclusively adjudicated in the other suit, when it has been proved that he was there precluded from offering evidence in support of his contention because of the opportunity to enforce his rights which this action afforded. The ruling which had that effect was made by the same judge who afterwards presided at the trial of the present case, and who declined to regard the former judgment as conclusive against the right here *260 asserted. Judge Heuisler, who made both rulings, is said to have - acted upon the theory that it would not be fair to conclude the appellee’s claim" which exceeded in amount the jurisdiction of the Peoples’ Court, and of the Baltimore City Court on appeal, by adjudicating it as a defense to a muchl smaller claim for which that jurisdiction was available. Whatever may have been the ground of the earlier ruling, which is not reviewable, the judge who presided at both trials could have had no difficulty in determining whether they actually involved a decision of the same issue on the merits. In view of the special conditions shown by the record, we think he was justified in holding that the former judgment was not a bar to the present suit.

Exceptions were taken to the admission of the parol evidence as to the restricted scope of the trial in the Baltimore City Court. This testimony, we think, was competent to prove the fact to which it was directed. Whitehurst v. Rogers, 38 Md. 515; Streeks v. Dyer, 39 Md. 424; Boggs v. Boggs, 138 Md 439; 15 R. C. L. pp. 1050-2; 1 Poe, Pl. & Pr., sec. 655.

The evidence on the issue of res- adjudicatei being uncontradicted, the court below properly decided the question as one of law, and there was no¡ error in its refusal to- direct a verdict for the defendant on that issue or to submit it to the jury.

One of the appellant’s prayers sought to have the jury instructed to render a verdict for the defendant if they should find that the appellee violated the rule of the road giving the right of way, at road intersections, to one approaching from the right. There is no evidence in the record as to the circumstances of the accident, and we havej therefore, no means of determining whether the theory of the prayer had any support in the proof. The refusal of the prayer must be presumed to have been proper, in the absence of any basis in the record for a conclusion that the ruling was erroneous.

Judgment affirmed, with costs.
