Factual and other preliminary controversies
24 Was there in truth an inconsistency between (a) the finding that it was foreseeable that a person could squeeze through the window and that such a person was at risk of sustaining a very serious injury, and (b) the conclusion that this could only occur with difficulty, and was not probable? There is no inconsistency. The window was very small and the conduct was unusual. The finding that there was a "risk" of a very serious injury is not inconsistent with a finding that it was foreseeable but not probable.
25 The plaintiff's contention that the trial judge should have found that there was a high degree of foreseeability because of his evidence that it was "quite easy" to get out the window, and that the trial judge accepted this evidence, overlooks the difficulty that he in fact rejected it. He rejected it on the basis that the manoeuvre was intrinsically difficult, and though the plaintiff became adept at it it was only because he had done it on many occasions.
26 The plaintiff's submission that since at the time of the accident many of the defendant's trains were without gaskets or had worn gaskets, they "provided no security" is a tendentious way of describing the opportunity afforded to the plaintiff and others to do what they did. Even without the gaskets, the windows opened only 235 mm, and the plaintiff's manoeuvre required considerable agility and determination, according to findings of the trial judge which have not been challenged. There was also an unchallenged finding that to determine whether a rubber gasket remained in place would require a close inspection of each window during nightly cleaning, and this could not be done without "a greatly increased staffing requirement" and "a consequential significant cost".
27 That point also bears on the plaintiff's submission that the defendant "must be taken to have been aware" of the deficiencies in the gaskets, because the finding negates awareness of the risk for which the plaintiff contended, ie that "many" of the trains had the deficiency.
28 The plaintiff's criticism of the trial judge's failure to find that the defendant was aware of the manoeuvre employed by the plaintiff and others fails. There was evidence that Mr McColl and Mr Logue saw graffiti above windows on the roofs of trains, but in positions where it could have been placed by a person standing inside a train and moving only his arm outside the window. Mr Cowling, who had examined many of the defendant's documents and other materials, found nothing to indicate that people were squeezing their bodies through windows to spray graffiti before the accident. The trial judge did not reject this evidence and no error has been demonstrated in his refusal to do so.
29 There is a qualitative difference between the manoeuvres by which youths extended their arms out of doors, windows and the ends of carriages, and the manoeuvre employed by the plaintiff, with the whole of his torso out of the window and his buttocks resting on the window edge. The relevant witnesses admitted to, or were found to have, the former awareness. They denied the latter awareness, and no argument was advanced which demonstrated that the trial judge was wrong in accepting the denials. But awareness of the latter manoeuvre cannot be inferred from knowledge of the former.
30 The reliance on newspaper reports to demonstrate the defendant's knowledge of the practice engaged in by the plaintiff fails. Not all the articles relate to the period before the plaintiff's accident. In general they are summaries without precise sources being ascribed. They deal with hanging out of doors as well as hanging out of windows. It is not clear that the windows referred to are windows in carriages of the type in which the plaintiff was injured: there were other types of carriage in which it was possible to lean out of the windows.
31 The defendant placed considerable reliance on various things said in Modbury Triangle Shopping Centre Pty Ltd v Anzil (2000) 205 CLR 254, while the plaintiff was at pains to distinguish that case. Thus the defendant pointed to what was said in that case about identifying the nature of the harm suffered, the relevance of lack of control by the defendant, the relevance of criminal conduct, the lack of reliance by the plaintiff on the defendant, the fact that the defendant had not assumed responsibility for the plaintiff, and the relevance of whether a special relationship existed. Save to the extent that the Modbury case deals with the law of negligence generally, it is desirable to put it on one side in the instant case. The Modbury case was sharply focused on the problems that arise from criminal conduct by third parties not by plaintiffs. It is true that in principle the difficulties it described in relation to injuries caused to plaintiffs by the criminal conduct of others are likely to have parallels in relation to injury caused to plaintiffs by their own criminal conduct. The plaintiff contended that it had not been demonstrated that he had engaged in any crime at the time of his accident. His arguments in that respect are not convincing, but it is not necessary to reach a conclusion about them. Since it is possible to decide the instant case without using the specific reasoning in the Modbury case, it is undesirable to consider whether that case has any impact on the liability of defendants for injuries caused by the illegal conduct of plaintiffs as distinct from third parties.
32 There was a controversy between the parties as to the necessity for proving knowledge in the defendant of the plaintiff's conduct. The defendant said there was. The plaintiff said that constructive notice sufficed. Each side claimed to gain support from Crimmins v Stevedoring Industry Finance Committee (1999) 200 CLR 1 at [101]-[102] per McHugh J. The defendant could have obtained comfort from the fact that particular (viii) in the Particulars of Negligence in the Amended Statement of Claim based the alleged negligence on the defendant's "knowledge". The controversy appears to go only to foreseeability: if the defendant knew that youths were engaging in the conduct on which the plaintiff was engaged, it would increase the foreseeability of the risk. Despite the way particular (viii) is framed, however, if all other obstacles to recovery were overcome, the plaintiff would not necessarily fail on the ground that he did not prove that the defendant knew various things, so long as he proved that the defendant ought to have known them.
33 The plaintiff's argument that the defendant ought to have employed the funds spent in removing graffiti each night in remedying the windows, which measure would have prevented the placing of the graffiti, must fail. It was not put to any witness at the trial. The argument assumes that most of the graffiti was applied by people using the windows, whereas there is evidence that they used doors and the ends of carriages as well, and Mr Cowling said that the bulk of the graffiti was actually applied at night while the carriages were "stabled" in carriage sheds and workshops.
34 Counsel for the plaintiff rightly identified a crucial difference between the positions of the parties. He said that while it was common ground that reasonable foreseeability of injury alone did not create a duty, the defendant conceded a duty: the controversy was as to its scope. The parties were agreed that the duty was to take reasonable steps to provide a safe railway carriage. But while the defendant said that the duty was to exercise care in relation to dangers likely to arise from the ordinary use of the carriage which might reasonably be expected, the plaintiff said it was to exercise care in relation to dangers which might reasonably be expected, having regard to the defendant's actual or imputed knowledge of the behaviour of all passengers. That is the central issue in the case and it is now necessary to turn to it.
