causing the collision, a plea of res judicata must fail because the causes of action involved in the two proceedings are entirely different. In the case of the proceedings between Jackson and Goldsmith, Jackson would have asserted a common law right. As defendant in White's action he is asserting a special statutory right to contribution or indemnity.
On the other hand, Jackson, in his declaration of third party claim, alleges that Goldsmith " so negligently drove and managed his motor car upon a public highway that the same collided with a motor cycle driven by Jackson." This allegation, of course, states by no means the whole of Jackson's alleged cause of action against Goldsmith. But it states something which Jackson must allege and prove in order to succeed in his claim to contribution or indem- nity. On that allegation issue has been joined between Jackson and Goldsmith. If in former proceedings between Jackson and Goldsmith that very issue was determined in Goldsmith's favour as between him and Jackson, then Jackson is now precluded from alleging the contrary against Goldsmith. And a plea that that very issue was SO determined in those former proceedings will be a good plea of issue estoppel. The word "negligently" in the plea should be taken as meaning 'without exercising reasonable care."
No serious question of law, therefore, seems to me to arise in this case. The only real question is whether the plea on its proper construction does fairly raise such an issue estoppel. Undoubtedly the plea takes the general form of a plea of res judicata. It says, inter alia, that the two causes of action in the two proceedings were the same. This is an allegation entirely irrelevant to a plea of issue estoppel, and it is obvious, as I have pointed out, that the two causes of action are not the same. And the embarrassing nature of the plea as drawn is reflected in the grounds of the demurrer. Grounds 1, 2, 4, 5 and 6 are appropriate to a plea of res judicata, and, if the plea is to be treated as a plea of res judicata, are plainly good grounds for a demurrer. Ground 3, on the other hand, is appropriate to a plea of issue estoppel. But, if the plea were a properly drawn plea of issue estoppel, ground 3 could not be substantiated as a ground of demurrer. This is clearly pointed out by Maxwell J.
Street J. and Maxwell J. were clearly of opinion, as I am, that, regarded as a plea of res judicata, the plea could not stand. They were also clearly of opinion, as I am, that a plea that the issue joined on the allegation of negligence in the declaration of third party claim had been determined in Goldsmith's favour in prior proceedings between Jackson and Goldsmith would be a good plea
