As a result of the proceedings in the District Court it is now res judicata between Jackson and Goldsmith that the damage to Goldsmith's vehicle was caused by the negligence of Jackson and that Goldsmith was not guilty of contributory negligence, but the issue of fact whether any damage which the passenger White may have suffered in the accident was caused by the negligence of Jackson or Goldsmith or both has never been taken and found in any court. White is therefore free to sue either Jackson or Goldsmith severally, or to sue them jointly. He has chosen to sue Jackson severally. Part III of the Law Reform (Miscellaneous Provisions) Act 1946 relates to contribution between tort-feasors and s. 5 (1) (c) provides, so far as material, that one tort-feasor who is made a defendant may recover contribution from any other tort-feasor who is or would if sued be liable in respect of the same damage, whether as a joint tort-feasor or otherwise. The right of the tort-feasor who is sued to recover contribution from another person therefore depends upon the proof that the other person is also a tort-feasor in respect of the plaintiff or, in other words, that the plaintiff would succeed in an action for damages against that other person. As a result of the accident Jackson had at one stage two possible causes of action. He might have sued Goldsmith for any damage to his person or property caused by the negligence of Goldsmith. He is now estopped by the judgment of the District Court from bringing this action. If sued by White he might have sued Goldsmith for contribution under the Law Reform (Miscellaneous Provisions) Act. He has now been sued by White and has taken proceedings against Goldsmith under this Act. "The proceedings by the defendant against the third party are independent of and separate from the proceedings by the plaintiff against the defendant, except that, when the defendant is made liable to the plaintiff, he then has his right open against the third party to establish, if he can, that he possesses a right to indemnity and contribution from that third party" (Hordern-Richmond Ltd. v. Duncan [1] ). But, as I have said, the issue in these proceedings is whether any damage to White was caused by the negligence of Goldsmith. The proceedings in the Supreme Court are not therefore proceedings which, though different in form, raise the same issue of fact as that raised and found in the action in the District Court. The decision of Cassels J. in Johnson v. Cartledge and Matthews; Matthews (Third Party) [2] , is precisely in point. It was contended for the respondent that this decision is inconsistent with the decision of the Court of Appeal in Marginson v. Blackburn Borough Council [3] , and is wrong. With respect, I am of opinion that there is no such inconsistency and that the decision in Johnson's Case [2] is right. Marginson's Case [3] is, I think, clearly distinguishable. It was there held that Marginson as plaintiff was estopped by the previous proceedings in the County Court from bringing an action against the corporation as owners of the motor omnibus for the personal injuries which he had received in the accident. The accident resulted from a collision between a motor car driven by his wife as his agent and a motor omnibus driven by an agent of the corporation and in the County Court the issue had been taken and found that the drivers of the two vehicles were equally to blame for the collision. The issue in the new action was therefore the same issue as one of the issues already litigated in the County Court. The Court of Appeal, referring to this issue, said "This seems to us to be a clear decision on the same issue between the same persons litigating in the present case, and establishes conclusively, albeit in the County Court, in a claim by the defendants against the present plaintiff, that both were equally to blame." [4] . In The Queen v. Hartington Middle Quarter [5] , a case recently applied by the Court of Appeal in In re Koenigsberg [6] , Coleridge J. pointed out [7] that the question is "Whether the judgment concludes, not merely as to the point actually decided, but as to a matter which it was necessary to decide, and which was actually decided, as the groundwork of the decision itself, though not then directly the point at issue. And we think it does conclude to that extent." The liability of Goldsmith to White for any damage that White may have suffered was not in any sense the groundwork of the decision in the District Court. It was not the same but a different damage which was then in issue. Although the decision of Knight Bruce V.C. in Barrs v. Jackson [1] , was reversed on appeal, there is a passage in his judgment which has been cited repeatedly in subsequent cases, Ord v. Ord [2] - "It is, I think, to be collected, that the rule against re-agitating matter adjudicated is subject generally to this restriction - that however essential the establishment of particular facts may be to the soundness of judicial decision, however it may proceed on them as established, and however binding and conclusive the decision may, as to its immediate and direct object, be, those facts are not all necessarily established conclusively between the parties, and that either may again litigate them for any other purpose as to which they may come in question, provided the immediate subject of the decision be not attempted to be withdrawn from its operation, so as to defeat its direct object" [3] . No doubt the facts which will be litigated between Jackson and Goldsmith in the Supreme Court will be substantially the same facts as those litigated in the District Court but they will be litigated for a different purpose, and to prove or disprove a different issue.
