The question of the duty and its content
34There was no issue about the respondent owing the appellant a duty of care. Its content must, however, be considered. Mr Price was an adult. He took a seat. A game of tennis began. It was played in the manner described by Ms Andrews.
35The custody of Mr Price involved detention and an assumption of control of his person resulting in a duty to exercise reasonable care for his safety during his detention: Howard v Jarvis [1958] HCA 19; 98 CLR 177 at 183 (Dixon CJ, Fullagar J and Taylor J). The relationship is a special one sufficient to include a responsibility to exercise care to prevent harm deliberately and unlawfully inflicted by others: State of New South Wales v Napier [2002] NSWCA 402 at [14]-[21] and cases there cited (Spigelman CJ) and [66]-[83] (Mason P); and see New South Wales v Bujdoso [2005] HCA 76; 227 CLR 1 at 9-10 [32] and 14-15 [45]-[46] (the Court). Critical to the special character for relevant purposes here is the control by the respondent of the appellant and its assumption of responsibility over the appellant. These matters no doubt pervade the whole life and existence of those in prison: most aspects of life, and autonomous existence, are subject to control and direction. These considerations often assume their importance in the responsibility to control the violence of third parties, such as other inmates. These considerations are relevant, however, in recognising the duty no doubt extends to the taking of reasonable care in the exercise of powers of control and direction that exist in order to avoid injury to an inmate.
36Section 5B is in the following terms:
"(1) A person is not negligent in failing to take precautions against a risk of harm unless:
(a)the risk was foreseeable (that is, it is a risk of which the person knew or ought to have known), and
(b)the risk was not insignificant, and
(c)in the circumstances, a reasonable person in the person's position would have taken those precautions.
"(2) In determining whether a reasonable person would have taken precautions against a risk of harm, the court is to consider the following (amongst other relevant things):
(a)the probability that the harm would occur if care were not taken,
(b)the likely seriousness of the harm,
(c)the burden of taking precautions to avoid the risk of harm,
(d)the social utility of the activity that creates the risk of harm."
37Section 5B has now been discussed in many cases. It has been accepted as a statutory expression of the formulation of Mason J (as he then was) in Wyong Shire Council v Shirt [1980] HCA 12; 146 CLR 40 at 47-48: see Waverley Council v Ferreira [2005] NSWCA 418 at [45], Roads and Traffic Authority (NSW) v Refrigerated Roadways Pty Ltd [2009] NSWCA 263; 77 NSWLR 360 at 397-398 [178]-[179] and Harmer v Hare [2011] NSWCA 229 at [209]-[213]. This involves a contextual and balanced assessment of the reasonable response to a foreseeable risk: Roads and Traffic Authority (NSW) v Dederer [2007] HCA 42; 234 CLR 330 at 354 [69].
38None of these principles was in issue. What was in issue was the adequacy and acceptability of the primary judge's analysis.
39With respect to his Honour, [70]-[74] of his reasons do not reveal the undertaking of the task in s 5B or Shirt . There seems no dispute that there was an obvious danger - it was pleaded by the respondent. This was not, however, a warning case for Div 4 of the Civil Liability Act ; nor was Mr Price engaging in a recreational activity for Div 5. What was obvious was that he may be hit by a tennis ball. He was substantially in line with the direction of the ball being hit. Thus some injury was readily foreseeable. Commonsense would tell anyone that any blow, depending on its force, might be to the limbs, body, head or face. Whilst it might be expected that the probability of truly serious injury might not be high, it could not be said to be remote in the sense of fanciful. Further, injury such as a hit on the face, side of the head or neck or throat might well be significantly more than minor. These are risks that hardly needed expert evidence to illuminate. It was, however, led. Mr Farr-Jones was called by the appellant and Mr Edmondson was called by the respondent. The latter accepted that someone sitting behind the baseline was vulnerable to being hit: Black Book Vol 2 pp 420-421. As to the seriousness of the injury, that depended he said on where you were hit: Black Book Vol 2 p 422. Ms Andrews accepted that a person in the position of the appellant could have been hit: Black Book Vol 2 p 525. His Honour in expressing some doubt about the utility of some of the expert evidence said (at Black Book Vol 1 p 230):
"HIS HONOUR: Yes. Well I don't know that I need any expert evidence, you get hit in the eye, there's a risk of injury, but what's the magic in all of this?
KENNEDY: Being hit by a tennis ball in any part of your body, your Honour, is a risk of injury --
HIS HONOUR: Well this plaintiff was hit, on his case, with a tennis ball at some force.
KENNEDY: Yes.
HIS HONOUR: I wouldn't have thought I needed any expert evidence to know that if that happened the eye is likely to be injured.
KENNEDY: Exactly, your Honour. Well I would assume that to be so, your Honour.
HIS HONOUR: I don't know what the mystery about that is."
40Ms Andrews observed the play. I have already discussed her evidence on this matter. It can be accepted that the game was being played responsibly by all. Ms Andrews refused to say that they were playing aggressively or forcefully. Yet the blow Mr Price received hit him with a degree of force. There was no suggestion that this was an atypical shot or horseplay. No evidence was led of the shot in question. But Ms Andrews' evidence of how the game was being played enables an inference that the force with which he was hit was reflective of how the game was played.
41Ms Andrews in her evidence (set out at [22] above) gave her assessment as to what she would have done if they were playing "aggressively" or if the ball was "going wildly around". She would have moved the inmates, including Mr Price, from behind the court. Rather, she said that there wasn't anyone playing so aggressively that she thought anyone would be hit.
42That was a contemporaneous assessment by Ms Andrews. It was not, however, the basis of the primary judge's reasons, although it may have informed his view that the risk of serious injury was remote because of Ms Andrews' own view that without aggression or the ball going about wildly no one would be hit.
43The difficulty that I have with Ms Andrews' and the primary judge's assessments is that neither is either logical or supported by the straightforward facts or commonsense. As to Ms Andrews' view, it does not follow that no one would be hit unless the game was played aggressively or the ball was "going wildly around". A highly competent player was playing; the other three had sufficient competence to permit a proper game of tennis. Mr Price was in the line of play. He plainly could be hit on the successful passing of any player, whether by serve, passing or other shot. The game necessarily involved the risk of a ball coming in his direction at some speed. A physical injury could plainly occur. As to the primary judge's view, it cannot be said that the risk of serious injury was remote in the sense of fanciful. A ball hitting the nose, teeth, eye, throat, testicles or other parts of the body might cause injury of a not inconsequential, perhaps serious, kind - as indeed it did. Danger of some character was obvious - the respondent so pleaded. I do not see any real basis for the conclusion in [73] of the primary judge's reasons.
44Further, the nature of the risk and the extent of possible injury, depending upon where one was hit, could have been eliminated easily and without cost or other inconvenience by asking or requiring Mr Price and others seated in similar positions to move from behind the court. The evidence was that he would have complied - he had no alternative but to do so. There was no evidence that this would have created a risk of disturbance in the yard.
45In my view, the primary judge erred in his assessment of the risk and of the matters in s 5B. The risk was foreseeable, indeed obvious: s 5B(1)(a) and (b). Precautions as to moving Mr Price were such that a reasonable person would have taken given the degree of risk and absence of improbability of being hit: s 5B(2)(a), the possible seriousness of the harm (depending where one was hit): s 5B(2)(b), the minor burden of the precaution: s 5B(2)(c) and the lack of affectation of the social utility of the game that created the risk while Mr Price was seated where he was: s 5B(2)(d).
46Whether or not the failure of Ms Andrews to take the required step of moving Mr Price and any others in his position was a function of her focusing on questions of security in her position as Rover need not be considered in detail. At one point in her evidence (Black Book Vol 2 pp 526-527) she said that if the inmates chose to sit where they did it was not her job to move them. In her own defence, she said that she saw "no possibility of a risk" (Black Book Vol 2 p 527).
47For the reasons earlier expressed, I do not accept that there was no possibility of risk. The risk was obvious. The question was whether the risk was of a sufficient character (as to probability and possible degree of harm) as to require, for the exercise of due care, that Mr Price and any others behind the court be asked to move. In my view it was.
The question of the acceptance of Ms Andrews' evidence
48Detailed submissions were put as to why Mr Price should have been accepted and why Ms Andrews should not have been accepted. All involve a detailed examination of aspects of the evidence of each. None involves any matter of incontrovertible evidence that tells against Ms Andrews' truthfulness.
49It would be fruitless to examine all the matters set out at paras 115-131 of the appellant's written submissions and the oral address. Taken individually and collectively they are inadequate to permit this Court to make a finding contrary to that made by the primary judge with his advantage of seeing the witnesses give their evidence over an extended period of time.
50In any event, I do not see the acceptance of Ms Andrews' evidence as crucial to the disposition of the appeal, except perhaps as concerns contributory negligence.
