The manner in which the question of liability was left to the jury will be gathered sufficiently from the following passages from the summing up of Brereton J., who presided: "The first question I said you have to ask yourselves was this - Was the defendant employed on the roof? You see, if he was not required by his employer to go on the roof that is an end of the matter and there would be a verdict for the defendant. If a reasonably prudent employer had foreseen that an employee acting in a normal manner would go on the roof then he would be in the same position as if he were actually required to go there, because the employer's duty of care extends not only to the places in which it is vitally necessary for the man to go, but to places into which a reasonably prudent employer would expect a normal acting employee to go. The second question, if you come to the conclusion that he would be expected to be likely to go on to the roof, is this - did the employer fail to exercise towards him, in allowing him to go on the roof, and in relation to this particular defect in the roof only, such care as a reasonably prudent employer would show to a man of his skill and experience?" The jury found a verdict for the plaintiff for £4,000, but the Full Court (Street C.J., Owen and Herron JJ.) set it aside on the ground that there was no evidence that the defendant by his servants or agent had been guilty of negligence.
