Breach of duty
37 I do not agree with the basis on which the trial judge found that any duty of care that Mr Abraham may have owed Christopher was not breached.
38 Firstly, in my view, the question whether the system of supervision was adequate or not was a matter of commonsense. It was something that any parent, with knowledge of the facts, should have been able to judge. The judge found that Mr Abraham knew that there was no formal system of supervision and that only the ad hoc informal system, the details of which I have described, was in place. Mr Abraham knew that the prospect of a teacher being present to observe the behaviour of children in the covered area and its surrounds depended on "coincidence". With that knowledge, it required no special skill or expertise to appreciate that the system was inadequate.
39 Secondly, it is no answer to the allegation of breach of duty that Mr Abraham relied on the College to comply with the system of ad hoc informal supervision. The point is that Mr Abraham knew, or should have known, that that system was inadequate.
40 Mr Campbell SC, who, together with Mr Stockley, appeared for St Mark's, adopted the proposition that once it is accepted (as the judge held) that St Mark's was negligent, Mr Abraham should also be held to have been negligent as he had the same knowledge as St Mark's and was able to control Christopher's presence in the inadequately supervised environment.
41 The point, however, is that the College owed a duty not only to the individual students but to the students (all 382 of them) as a class: Geyer v Downs (1977) 138 CLR 91; Wyong Shire Council v Shirt (1980) 146 CLR 40 (at 47 per Mason J); Vairy v Wyong Shire Council (2005) 223 CLR 422 (at 432 to 433, [27] per McHugh J).
42 St Mark's was required to take into account the risk of injury to the class comprised of 382 students (including Christopher). The risk so to be assessed involved the risk of one or more of those students suffering harm during the period from 7.45 am each day (when students had already begun to arrive and from which time, according to St Mark's, supervision should have been formally undertaken (but, in practice, was not) until 8.35 am (when classes commenced). Mr Abraham, on the other hand, was required to take into account the risk of injury to Christopher, alone, on a single occasion on 23 August 2000 between 8.00 am and 8.20 am. The risk was that Christopher, a dutiful child, might be mischievous and something untoward might happen to him in that short period.
43 Accordingly, the risk of harm that St Mark's was required to take into account differed substantially from that which Mr Abraham had to consider. The former was far greater than the latter and obviously required the taking of precautionary measures that did not apply to the risk that Mr Abraham had to bear in mind. There was no inconsistency and no anomaly in the judge's findings.
44 Mr Campbell accepted that it would not have been negligent for Mr Abraham to have first taken his daughter to the childcare centre, then taken Christopher to the covered area in the College while he, Mr Abraham, went about his duties (in the staff room or classroom, where he would prepare for his classes for the day). Mr Campbell accepted that there would be no negligence in those circumstances as Christopher would be more likely to obey the rules while his father was on the premises and Mr Abraham, himself, might have been in a position, from time to time, to keep an eye on Christopher. Further, Mr Abraham's duties, as a teacher at St Mark's, required him to be doing other things from 8.20 am onwards and it would have been unreasonable for him not to have complied with those duties. Thus, the negligence alleged amounts to leaving Christopher at school between 8.05 am and 8.20 am, a period of 15 minutes.
45 I would preface what follows by noting that not all the facts that I recount were expressly found by Rothman J. Those that were not so found are based on the evidence given by Mr Abraham. This course is open as his Honour said (at [47]) that he accepted Mr Abraham's evidence "without qualification". The judge said that Mr Abraham's "manner and demeanour displayed a remarkable integrity". His Honour said that Mr Abraham "gave the impression that great effort was taken to ensure as accurate an answer as possible" (at [47]).
46 As I have mentioned, Mr Abraham had on a few occasions previously dropped Christopher off at school before taking his daughter to the childcare centre. Mr Abraham thought that this was appropriate as it would allow Christopher to gain in confidence and maturity. This was his reason for doing the same thing on 23 August 2000.
47 Mr Abraham had done this in the knowledge that not all children complied with the instruction to remain seated in the covered area before classes began. He said that only about two-thirds of the children would "do the right thing".
48 On the morning of 23 August 2000, Mr Abraham realised, from the cars in the teachers' carpark, that some teachers had already arrived at the College. This was a factor that he bore in mind when he dropped Christopher off first.
49 That morning, he told Christopher to "be a good boy; you know where you are supposed to be seated; don't do silly stuff". Christopher was an obedient child and Mr Abraham thought that he would behave properly and do nothing untoward. He regarded the proposition that Christopher might climb onto the railing and sit upon it as a "wholly surprising thing for Christopher to do". He did not think that Christopher was capable of the behaviour that resulted in his injuries. He was "in shock" after learning what had happened.
50 When Mr Abraham left Christopher at the College on the morning of the accident, he thought that, in all the circumstances, it was in Christopher's best interests to spend the brief time before school started with his friends. He thought that Christopher would be safe. He was wrong, and the question is whether his decision was reasonable. The question of negligence depends on the answer to this question. As Gleeson CJ observed in Woods v Multi-Sport Holdings Pty Limited (2002) 208 CLR 460 (at 472, [39]), in determining negligence, the question is, ultimately, "what a reasonable person, in the position of the defendant, would do by way of response to the risk." See also Shirt (at 47 per Mason J), Vairy (at 456, [105] per Hayne J), New South Wales v Fahy (2007) 81 ALJR 1021 (at 1034, [56] per Gummow and Hayne JJ, 1044, [108] per Kirby J, 1062, [214] per Callinan and Heydon JJ). This is a question of judgment for the court.
51 The legal principles applicable to the law of negligence must accommodate the practical realities of everyday living: Neindorf v Junkovic (2005) 80 ALJR 341 (at 345, [8] per Gleeson CJ). One of those practical realities is that the bringing up of children cannot be made risk-free. It is inevitable that children, even in the most careful and ordered households, will be exposed from time-to-time to risks of harm. This is inherent in the process of growing up, undergoing new experiences, and maturing in an appropriate way.
52 The risk to which Mr Abraham exposed Christopher was on the brink of foreseeability in the Shirt sense. For the risk to materialise in the brief period between 8.00 am and 8.20 am in which he was left at the College, Christopher had to be incited to act mischievously by other students, he had to disobey the express instructions he had been given and thereby act completely out of character, his conduct had to be unnoticed by the teachers present at the College, and he had to act in such a way as to cause himself harm. It was not likely that all these factors would coincide. On the other hand, Mr Abraham, understandably, believed that there were potential benefits to Christopher in allowing him to be at school during this period.
53 In my opinion, taking all the factors that I have mentioned into account, Mr Abraham acted reasonably. I do not think that he was negligent.
