Consideration
37The question whether the respondents were guilty of breach of duty turns first on determining whether the risk in question is one of which the defendant knew or ought to have known: s 5B(1)(a). This means the risk must be defined. Before doing so, however, it is essential to determine the scope of the duty of care the respondents owed the appellant.
38The respondents, as occupier of the land onto which the appellant entered, owed her a duty to take reasonable care to prevent injury to her on the assumption she was using reasonable care for her own safety: Australian Safeway Stores Pty Ltd v Zaluzna [1987] HCA 7; (1987) 162 CLR 479 (at 487-488) per Mason, Wilson, Deane and Dawson JJ; Jones v Bartlett; [2000] HCA 56; (2000) 205 CLR 166; Roads and Traffic Authority (NSW) v Dederer [2007] HCA 42; (2007) 234 CLR 330 (at [47]) per Gummow J. There was no suggestion that the appellant had fallen short of the last requirement.
39What was reasonable turns on the circumstances of her entry upon the premises: Australian Safeway Stores Pty Ltd v Zaluzna (at 488). The duty to take reasonable care required the respondents to protect the appellant, or the class of person of which she was a member, from a "not insignificant" risk which could reasonably be foreseen and avoided. The measure of the discharge of the duty, at common law, was what a reasonable person would, in the circumstances, do by way of response to the foreseeable risk: Hackshaw v Shaw [1984] HCA 84; (1984) 155 CLR 614 (at 663) per Deane J. The measure is now prescribed by s 5B of the Civil Liability Act.
40The inquiry about whether the respondents ought to have taken the precautions for which the appellant contends turns on (amongst other relevant matters) the foreseeability of the risk, whether that risk was not insignificant and whether in the circumstances, a reasonable person in the person's position would have taken those precautions. The inquiry is not to be undertaken in hindsight (Vairy v Wyong Shire Council [2005] HCA 62; (2005) 223 CLR 422 (at [126]) per Hayne J), but must be answered prospectively, before the incident occurred: Adeels Palace Pty Ltd v Moubarak [2009] HCA 48; (2009) 239 CLR 420 (at [31]).
41The inquiry is not confined to what could have been done to eliminate, reduce or warn against the risk. While asking what could have been done will reveal what was practicable, it is necessary to ask also: would it have been reasonable for the respondents to take those measures?: Neindorf v Junkovic [2005] HCA 75; (2005) 80 ALJR 341 (at [93]) per Hayne J. In other words, the knowledge of how the appellant actually came to sustain her injury has to be excluded when considering whether the respondents were obliged to take any precautions in the circumstances of having a dog in the house to which guests had been invited: Neindorf v Junkovic (at [96] - [97]) per Hayne J.
42A person does not breach his or her duty of care merely because there are steps that he or she could have taken to avert the risk that actually materialised: Thornton v Sweeney [2011] NSWCA 244; (2011) 59 MVR 155 (at [131]) per Sackville AJA (Campbell JA and Tobias AJA agreeing).
43The first question which must be asked is whether the presence of the dog in the house posed a foreseeable and not insignificant risk in the circumstances: s 5B(1)(a) and (b). Only if that question is answered in the affirmative does the question arise as to what a reasonable person would do by way of response to the risk: s 5B(1)(c). That was the approach the primary judge took. Having answered the first question in the negative he did not proceed further.
44The appellant placed much emphasis on the description of the dog as "dangerous", a label the first respondent apparently ascribed to the animal after the incident and without elaboration. However the appellant dwelt on the fact that the dog was a "trained hunting dog". This was said to support the submission that she feared such a dog would hunt and slay its prey.
45There was no evidence from the appellant that she feared the dog for that, or indeed, any particular reason. Rather, it will be recalled, her evidence was that she did not like dogs in general and would "take steps to avoid any dog". As I have said there was no evidence the respondents were aware of that tendency. The respondents submitted she had a "phobia" in this respect, a description the appellant eschewed. I would not place any reliance on that label, just as I would not place any weight upon the first respondent's ex post facto description of the dog as "dangerous".
46More significant, in my view, approaching the incident prospectively, is that the respondents (in this case the second respondent) were prepared to allow the appellant and her companions to enter the house while the dog was in the lounge room. It might be inferred that, therefore, they (in particular the second respondent) were of the view that the dog posed no risk to entrants in such a situation. That inference is borne out by the fact the dog did nothing which could be characterised as aggressive before the appellant took the two to three steps to the front door. I do not accept that the respondents ought to have foreseen that an entrant might have a general fear of dogs, or, confining the inquiry to the appellant (Shaw v Thomas [2010] NSWCA 169; (2010) Aust Torts Reports ¶82-065 (at [40]) per Macfarlan JA; (Beazley and Tobias JJA agreeing) that they ought reasonably to have foreseen her reaction.
47In my view the primary judge was entitled to conclude in those circumstances that it was not incumbent on the respondents to foresee that there was a risk that the appellant would, upon seeing the dog in the house, fear it and run from the house in panic. The appellant's submissions appear to be shaped more through the prism of hindsight than foresight.
48On one view, as the primary judge found, it could be said that what befell the appellant had little to do with the presence of the dog. She left the premises hurriedly and slipped on a wet patio. In other words, she had removed herself from any area of what might have been envisaged as foreseeable danger before she was injured, having left the respondents' premises and closed the door behind her. It was when she turned that she slipped on the tiles on the landing which were wet because there had been light rain. The appellant contended at trial that this slip was also a foreseeable consequence of the respondents' failure to take reasonable precautions for her safety, that is to say that she might fall and injure herself in the course of fleeing the dog. It is unnecessary to consider this further as the appellant has not established the "triggering event" which might place this part of the incident within the class of foreseeable risk.
49In my view the primary judge did not err in concluding the appellant had not established that the risk of injury was foreseeable.
