That is, her Honour did not find that Mrs Sutton was negligent in accelerating to exit the depression.
47 Next, her Honour at one point described "the emergency" as the situation which was created when the cart, Mrs Sutton having accelerated it, headed towards the bushes on the left.[28]
48 Now the judge found that the distance from the depression to the point of collision was closer to 9 metres than 2 to 3 metres. That was really the foundation for her Honour's finding that Mrs Sutton had time to bring the cart to a stop "from the rising of the emergency"[29] But if the emergency arose somewhat later than when the wheel entered the depression, the distance "from the rising of the emergency" to the point of collision may well have been less than the distance from the depression to point of collision, and inadequate for the cart to be brought to a stop.
49 Whether or not that be so, the less the distance and the shorter the period of time between the immediate consequences of the Club's breach of duty and the collision, the weaker becomes the Club's already weak second causation argument.
Contribution
50 The learned judge did not mention in her reasons the two comparisons which must be made in determining contribution between tortfeasors. But for the reason explained by Callaway, J.A. it should not be concluded that her Honour was unaware of the proper approach, or that she did not turn her mind to it.
51 The question, then, is whether the Club has demonstrated some fault in what was a question of proportion, balance, emphasis, and the weighing of different considerations - to paraphrase a well-known passage in Podrebersek v. Australian Iron and Steel Pty. Ltd.[30] According to the appellant's submission, the apportionment was plainly faulty. It must have been resolved substantially against - not in favour of - Mrs Sutton.
52 What fell for comparison here, as Callaway, J.A. has pointed out, was not conduct of the same kind. That circumstance, I think, makes the comparison more difficult. Be that as it may, I am of opinion, all things considered, that the apportionment arrived at by the trial judge was well within the available range.
53 As to culpability, the judge found that the Club's breach of duty lay in its creating a hazard in a well-trafficked area. The breach did not lie in siting the solenoid boxes in that area, or in their covers being set below ground level. It lay in failing to render the depression visible, so eliminating the particular hazard.
54 The action required of the Club for it to discharge its duty of care was simplicity itself. It could have been undertaken, within limits, at times of the Club's choosing, and with virtually no expenditure of time or money. Despite its simplicity, on the other hand, the required action was of importance. It was important having regard to the fact that it could confidently be expected that persons of differing ages, physical agility, visual acuity, co-ordination and the like, would be traversing the general area of the hazard.
55 I turn to the breach of duty found by the judge in respect of Mrs Sutton. It addressed a very short period of time - that is, Mrs Sutton's conduct in the few seconds after her cart moved in a sudden and unexpected fashion by reason of its front near-side wheel entering the hazard created by the Club. It is to be remembered that the judge attached no legal blame to Mrs Sutton's action in first accelerating the cart when its wheel entered the depression. Indeed, only as a matter of inference, if at all, could it be said that her Honour found that Mrs Sutton's oversteering to the right was negligent. Critically, as I read the judge's reasons, Mrs Sutton's negligence lay in her not bringing her cart to a stop before it collided with the plaintiff. Accepting - though see my earlier observations - that Mrs Sutton could have brought her vehicle to a stop in the period between "the rising of the emergency" and the collision, to my mind her culpability nonetheless ought be accounted much less than that of the Club.
56 I turn to causation. It would be easy to focus upon the immediacy of Mrs Sutton's failure to apply the brakes of the cart as a cause of the collision, and to relegate to a position of relative causal unimportance the role of the Club in not exposing the depression. But it was the Club which knew or should have known of the hazard, and it was the Club which had the expertise and equipment to eliminate the same. It had the opportunity to do so without the straitjacket of closely confined time constraints. It took no action. In my opinion, the hazard thus created should be described as the root cause of the plaintiff sustaining injury. Accepting Mrs Sutton's want of reasonable response to the situation which developed when her cart encountered the hazard, I do not accept that it causally predominated in the plaintiff suffering injury. I should add that even if I had been persuaded to a contrary view, I would still be of opinion that the judge's conclusion as to apportionment was within the available range. For, as I said a moment ago, I consider that the Club's culpability was much greater than was that of Mrs Sutton.
