The essential question of fact in this case was whether the driver of the vehicle in which the plaintiff's husband was killed was negligent, and whether that negligence caused the collision. That question was to be decided by the jury. If the jury were properly directed and nothing occurred which vitiated the trial, their verdict ought not to be disturbed. That they were correctly directed is I think indisputable. But it is said that the case for the plaintiff was in some way hampered, because, as it was put, counsel did not address the jury on "the doctrine of res ipsa loquitur". It is said that had he not been prevented by the learned trial judge, he would have urged that from the "mere fact of the collision" the jury might infer negligence on the part of the driver of the car in which the deceased man was. To support this criticism of the course and events of the trial a memorandum, as it was called, prepared and verified by the solicitor for the respondent was produced to the Court. I share the misgivings which have been expressed by the Chief Justice and by my brother Owen as to our considering this document. My doubts have been aggravated by my reading the remarks of the Court of Appeal in Thompson v. Andrews [1] . However we did receive the document; and I have given careful attention to it. It suggests to me that either it is a somewhat garbled account of what occurred at the trial or that counsel's submissions to his Honour were based on some misapprehensions of law and fact. The memorandum must, of course, be read with the shorthand writer's transcript of what occurred. In so far as counsel put to his Honour that what was called the "doctrine of res ipsa loquitur" shifted the onus of proof, his Honour rightly refused to accept this proposition. In so far as the submission was that the mere fact of a collision without more could found an inference of negligence on the part of the driver of one vehicle rather than the other, the proposition is obviously untenable. There was however more in this case. There was evidence that the car in which the deceased man was travelling swerved, without warning, across the road and into the path of the oncoming vehicle. It was for the jury to consider how far they accepted this evidence, and what inference they would draw from the facts as they found them. His Honour's remarks to counsel during the course of the trial amounted, it seems, only to this: that there was evidence that the collision occurred because the car suddenly swerved in its course; and that, that being so, the jury were not left with the mere fact of a collision; that they had evidence that it occurred because of the swerving of the car; that, if they accepted that as the fact, they must consider whether in all the circumstances they should infer from it negligence on the part of Hannon. His Honour's summing up to the jury put their task clearly before them. Some questions that they asked shewed that they had appreciated their task, and were considering the evidence which they took to bear on the issues they had to try, including matters indicative of the course of the vehicles. They would not, I think, have been aided in their task by being further told by counsel, either in a Latin phrase or in English, that they must consider what inference they should draw from the facts of the occurrence as they found them, and that one view of them would support an inference of negligence on the part of the driver of the car. It was for the jury to consider the evidence, and having come to a conclusion as to the facts to ask themselves what inferences they should draw from them. That they could draw an inference of negligence had been made clear to them. That they were not bound to do so, and that they must determine the issue on the whole of the evidence, was made equally clear. Their verdict was open to them on the evidence. Whether they arrived at it because they were not satisfied that Hannon was in fact the driver of the car, or because they found that he was, but were not satisfied that the collision was the result of negligence on his part, we do not know and need not, indeed must not, speculate. In my opinion the jury's verdict must stand. I have read what has been written by the Chief Justice and Owen J. I have added my remarks only to emphasize my concurrence.
