(c) the plaintiff had lost a chance of securing a better outcome.
7 It is convenient to note immediately the nature of her Honour's finding with respect to the breach of duty on the part of the ambulance officers. It was limited in its form and was expressed in the judgment at [40] in the following terms:
"I am satisfied that the ambulance officers breached their duty of care to the plaintiff in failing to inform the police officers:
1. Of the possible consequences of their inability to fully examine the plaintiff
2. That the plaintiff should be taken to a hospital to be medically assessed."
8 A finding in this limited form requires consideration of the powers, obligations and likely actions of the police officers, if the ambulance officers had taken the steps identified, and the likely response of the plaintiff. It is convenient, therefore, to consider the various questions of liability raised by the appeal and cross-appeal together, before turning to the challenge to the assessment of damages.
Facts and findings: liability of Ambulance Service
9 The plaintiff's case against the Ambulance Service was based on the failure of the two ambulance officers to take the steps noted above. The precise basis upon which the Ambulance Service was said to be liable was not articulated in the pleadings. The Ambulance Service is a statutory corporation and represents the Crown: Ambulance Services Act 1990 (NSW), s 4. Although the Ambulance Service has power to "appoint and employ" employees (see s 13(1)), the employer is the Health Administration Corporation: s 15(2). The Health Administration Corporation is also a statutory body representing the Crown: see Health Administration Act 1982 (NSW), s 9(2)(f).
10 The individual ambulance officers were not sued, presumably because they had immunity from liability for conduct carried out in execution of their duties, in good faith: Ambulance Services Act, s 26. Such a statutory immunity is to be disregarded in considering the vicarious liability of another person: see Law Reform (Vicarious Liability) Act 1983 (NSW), s 10(2). Whether either of the Ambulance Service or the Health Administration Corporation was vicariously liable for the acts or omissions of the ambulance officers appears not to have been the subject of debate in the proceedings, perhaps because of an apparent lacuna in the pleadings. In any event, the Ambulance Service did not, on the appeal, oppose a judgment against it if the officers were liable, on the basis that it was the wrong defendant.
11 Although the plaintiff was able to give limited evidence as to his consumption of alcohol on the afternoon of 27 July 2001, it is clear that he had been drinking heavily. On the basis of a blood sample taken at 12.30pm on the following afternoon, a pharmacologist expressed the view (which was not challenged) that his blood alcohol concentration at the time of the incident would have been about 0.4g%. There was also no challenge to the conclusion that he was an intoxicated person for the purposes of the Intoxicated Persons Act, being "a person who appears to be seriously affected by alcohol …": s 3.
12 At about 2am on the morning of 28 July 2001, the plaintiff was found by Police Constables Cosgayon and Fuhrer. He was lying prone across a driveway. The officers noticed a few droplets of blood on the driveway and a small cut to the plaintiff's head: Tcpt, 06/12/06, p 135 (Fuhrer) and p 169 (Cosgayon). The senior officer, Constable Cosgayon, gave evidence that they spoke to him and tried to find out what had happened. He described his speech as "a little bit slurred" and said he had formed the view that the plaintiff was "well affected by alcohol". He recalled asking him about the injury to his head, but recalled no clear response. The police called an ambulance. The ambulance records indicate that the call was received at 2.05am and that the ambulance had arrived by 2.19am. The senior ambulance officer was Mr Butt, who drove the vehicle, the treating officer being Ms Chapman. Ms Chapman was a probationary ambulance officer who had been with the Service for about 10 months at the time of the incident. Prior to commencing work with the Ambulance Service, she had completed a degree in nursing and had worked as a registered nurse for about 20 months. She described her service as a "third career", having previously worked for 12 years as a research officer with BHP, before taking time out from the workforce to raise a family, following which she obtained her qualifications in nursing.
13 As a result of the medical consequences of the plaintiff's injury, the New South Wales Police conducted inquiries into the events of the evening and obtained statements from those who were witnesses at the trial. The initial statements were taken within weeks of the incident: Ms Chapman's statement being dated 28 July 2001. The statements were thus taken quite shortly after the events and predated the trial by some five years.
14 Ms Chapman said that she approached the police and was told that the plaintiff "appeared to have a laceration to his head" about which they were concerned. She approached the plaintiff and asked if she could look at his head. She described him as sitting on the ground and rubbing the top of his head with his hand and saying things like, "[t]here's no blood on my head see". In her statement she said:
"I saw some dried blood on the left side of his head, towards the top area. The male continually kept moving and I had trouble seeing the injury. I could see dried blood on his head however I could see a small amount of swelling in front of the abrasion area. I was touching the area of the wound, examining it, and I didn't seem to elicit any painful response from the male. I was unable to visualise a wound due to dried blood. The area of dried blood was about 4 [centimetres approximately] in diameter. I couldn't see an open wound and the dried blood was very dry.
The male knocked my hand away a couple of times when I tried to help him. Adam my partner came over and as he came up the male said words to the effect, 'I haven't given you permission to examine me'. Adam said something like, 'Can we have a look at your head'. I made another attempt at examining the male and he started to push my hand away and moving his head about. The male was becoming [combative] towards me and wouldn't let us help him."
15 In her evidence in chief she said she had touched his head a couple of times (Tcpt, 07/12/06, p 191):
"Q. What was your purpose in doing that?
A. Just to assess the wound, if you've got a significant injury you get like a boggy mass associated with a lot of bleeding or a depressed skull fracture or something like that. Just to assess the quality of the skin there and that, to assess if there was any pain felt by the person when I touched it. …
Q. What did you [do] in terms of those intended investigations … what did you discover, was there a boggy mass?
A. No, no, there was - it was perfectly normal in that respect, he had just an egg on his head like when a child hits their head on the bench, like just a little half egg on [his] head, that was the only thing I could feel when I felt it. …"
16 The ambulance officers gave evidence that, in the circumstances, they could not examine or treat the plaintiff or take him to hospital, without his consent. They clearly did not have his consent. Although there was a case run at trial that greater efforts should have been taken to obtain his consent and carry out a more complete investigation, her Honour rejected that complaint and it was not reagitated on appeal. Indeed, the thrust of the plaintiff's case was not that the ambulance officers would have been able to make any definitive assessment of his condition, but rather that, as they should have appreciated, he needed to be taken to hospital for an adequate medical assessment of his condition. The plaintiff contended that the ambulance officers should have been alert to the need for a medical assessment at hospital, something the police officers would not have appreciated. If properly advised, however, the police should have taken him to hospital themselves.
17 Because they were not so advised, the police did not breach their duties by taking him to the police station, pursuant to powers under the Intoxicated Persons Act. However, the custody manager at the police station, Senior Constable Keeping, acting in accordance with the police protocol, should, the plaintiff argued, have arranged for immediate medical treatment.
18 Critical to the plaintiff's claim against the ambulance officers was their understanding of the circumstances at the time they left the plaintiff with the police. Her Honour summarised the evidence given by them in that respect in the following terms:
"11 Ms Chapman said that if the plaintiff had been willing to go to hospital they probably would have taken him because he had a laceration and a bump on his head. She was aware that there was a risk of a haematoma and that any head injury could be a significant head injury.
12 Mr Butt said that if the plaintiff had not refused help he would have taken the plaintiff to the hospital. He believed that the plaintiff required medical assessment because there could have been a significant head injury. The ambulance protocol required a person with a head injury to be taken to a hospital where he or she could be examined and tested by medical practitioners who had the capacity and the equipment to detect whether it was a significant injury.
13 The police officers saw that the plaintiff would not let the ambulance officers examine his head. They heard the ambulance officers ask the plaintiff several times whether he wanted to go with them to the hospital. The plaintiff was brushing their hands away and was not co-operating.
14 The ambulance officers decided to leave and told Constable Fuhrer that they could not treat the plaintiff if he did not want to be treated."
19 In assessing the complaints against the Ambulance Service, her Honour appears to have accepted the substance of this evidence and continued:
"38 Mr Butt said that he did not tell the police that the plaintiff may have a head injury and should be medically assessed. He said that in hindsight he should have done so.
39 I find that the ambulance officers should have articulated the possible consequences of their inability to complete their examination to the attending police officers. Those police officers did not have any formal medical or paramedic training. While they knew the plaintiff had a head injury they did not appreciate the possible consequences of the head injury. There was no reason for the ambulance officers to believe that the police officers had any appreciation of the possibility that the small laceration they could see at the back of the plaintiff's head could lead to a loss of consciousness and brain damage."
20 The evidence given by Mr Butt in that respect appeared at Tcpt, 07/12/06, p 259 in the following terms:
"Q. I want to put it to you that firstly, you did not tell the police that this man may have a head injury and should be medically assessed?
A. Correct.
Q. You did not do that is that right?
A. That's right.
Q. I want to put it to you that that is something that you should have done?
A. In hindsight I should have done it."
21 As her Honour recognised, there was a further step to be taken, namely to determine what would have happened if the ambulance officers had advised the police that the plaintiff needed to be taken to hospital, but that they, without the plaintiff's consent, could not do so. Her Honour made the following factual findings in that respect:
55 Constable Fuhrer said that if he had been told by the ambulance officers that the plaintiff should be taken to the hospital it was more than likely that he would have done so. He believed that he had the power to detain the plaintiff and take him to a responsible person such as a hospital in certain circumstances. Constable Cosgayon said that they would have taken the plaintiff if the ambulance officers had said ' This man should be taken to a hospital'.
56 I am accordingly also satisfied that the police officers would have taken the plaintiff to hospital if they had been asked to do so by the ambulance officers.
57 The consequence of my findings is that the plaintiff should have been taken to hospital from the scene and I find that he would have arrived at around 2.30 a.m. I find that there was a delay in the plaintiff arriving at hospital of about 8 hours."
Challenge to finding of liability: Ambulance Service
22 By way of cross-appeal, the Ambulance Service challenged the initial finding that it owed a duty of care to the plaintiff. In support of that ground, it referred to the general principle that a person is not responsible for the criminal behaviour of strangers, referring to the judgments in Modbury Triangle Shopping Centre Pty Ltd v Anzil [2000] HCA 61; 205 CLR 254. It also sought support from the decision of this Court in State of New South Wales v Napier [2002] NSWCA 402, a case upholding the liability of the State for harm suffered by a prisoner caused by the conduct of fellow prisoners.
23 This contention was misconceived. The plaintiff did not suggest that the Ambulance Service had a duty to prevent injury inflicted by strangers: he merely argued that the Ambulance Service had a duty to take reasonable care in treating injuries received in a criminal assault. That ambulance officers have a duty to take reasonable care in treating a person to whose assistance they have been called, should be uncontentious, whether the cause of the need for treatment is accidental injury, illness or the result of a criminal attack. Modbury Triangle is not authority to the contrary. Nor is any assistance obtained from cases such as Napier, addressing the circumstances in which prison authorities may be responsible for attacks by one inmate on another: see New South Wales v Bujdoso [2005] HCA 76; 227 CLR 1; State of New South Wales v Bujdoso [2007] NSWCA 44; 69 NSWLR 302.
24 An alternative argument was that no duty of care arose, or, if it arose did not continue, in circumstances where the person sought to be assisted rejected offers of help. This more restrained argument raised a different issue. Although it is commonly said that the existence of a duty of care is a question of law, it is not to be viewed as such, abstracted from a factual context: Cole v South Tweed Heads Rugby League Football Club Limited [2004] HCA 29; 217 CLR 469 at [56] and [81] (Gummow and Hayne JJ); Amaca Pty Ltd v AB & P Constructions Pty Ltd [2007] NSWCA 220; (2007) Aust Torts Rep ¶81-910 at [46]-[47] (Giles JA), [93] (Ipp JA) and [137]-[140]. Nor is there any bright line separating the existence of a duty from its scope and content in particular circumstances. Finally, the question as to whether a duty exists is not helpfully answered without consideration of the particular respects in which breach is alleged. For present purposes, nothing is gained by asking, in the abstract, whether ambulance officers owed the plaintiff a duty of care: the only relevant question is whether the ambulance officers owed the plaintiff a duty which required them to advise the police that the plaintiff needed to be conveyed to hospital.
25 To formulate the question at that level of particularity may be said to preclude the separate consideration of breach. In the present case that is so, but only because there is no dispute that the relevant advice was not given. Nor does it preclude a proper consideration of both the factual and legal elements of the question. Once the question is formulated with some precision, it will be apparent that the answer is not to be found in the willingness of the police to take the plaintiff to hospital or the views of the ambulance officers as to what, with hindsight, should have been done. The willingness of the police to take the plaintiff to hospital would undoubtedly be relevant to questions of causation which might arise once a breach of duty had been established; it does not assist in identifying whether the law imposes a duty of that kind in those circumstances. The fact that help would have been provided if sought, is not directly relevant to determining whether there is a duty to seek help.
26 The powers of the police with respect to intoxicated persons, now found in the Law Enforcement (Powers and Responsibilities) Act 2002 (NSW) ("the 2002 Act"), Part 16, were, at the time of the incident, contained in the Intoxicated Persons Act. With respect to people detained for questioning under Part 9 of the 2002 Act, the officer having responsibility for the detained person (the custody manager) "must arrange immediately for the person to receive medical attention if it appears to the custody manager that the person requires medical attention or the person requests it on grounds that appear reasonable to the custody manager": s 129. Although no such provision was found in the Intoxicated Persons Act (nor now in Part 16 of the 2002 Act) it may be accepted that a duty in similar terms would arise under the general law. Further, if one public authority having custody of a person with knowledge of a particular disability or susceptibility requiring care or medical attention, transfers the person to another public authority having similar responsibilities, the duty of care on the first will extend to passing on relevant information of that kind: see Kirkham v Chief Constable of the Greater Manchester Police [1990] 2 QB 283. By analogy, a similar duty would arise in the case of ambulance officers unable to provide relevant medical assistance, in circumstances where they know, or should know, that the person is about to be taken into custody by the police.
27 The argument below focused on the question whether the police had power to take the plaintiff to hospital. The trial judge found that they did by the combined operation of ss 3 and 5 of the Intoxicated Persons Act. The relevant operative provisions, found in s 5, were as follows:
" 5 Detention of intoxicated persons
(1) A police officer may detain an intoxicated person found in a public place who is:
(a) behaving in a disorderly manner or in a manner likely to cause injury to the person or another person or damage to property, or
(b) in need of physical protection because the person is intoxicated.
…
(3) An intoxicated person detained by a police officer under this section is to be taken to, and released into the care of, a responsible person willing immediately to undertake the care of the intoxicated person.
(4) An intoxicated person detained by a police officer under this section may be taken to and detained in an authorised place of detention if:
(a) it is necessary to do so temporarily for the purpose of finding a responsible person willing to undertake the care of the intoxicated person, or
(b) a responsible person cannot be found to take care of the intoxicated person or the intoxicated person is not willing to be released into the care of a responsible person and it is impracticable to take the intoxicated person home, or
(c) the intoxicated person is behaving or is likely to behave so violently that a responsible person would not be capable of taking care of and controlling the intoxicated person."
28 One purpose of the power to detain is to provide "physical protection" because, whether through incapacity or otherwise, due to intoxication, the person is unable to care for himself or herself. Such a situation can clearly arise in circumstances where the person is suffering an injury which requires medical attention. The fact that the person may decline medical assistance does not vitiate the power of detention. Nor does the fact that the person is presently refusing medical assistance necessarily vitiate the obligation to pass on to the custodian information relevant to the person's medical needs. Apart from other considerations, it may be reasonable to expect that a person who is significantly intoxicated may change his mind when the effects of the alcohol or drugs diminish.
29 Although the power to detain may arise in circumstances where a person is in need of medical treatment, there is no power to require the intoxicated person to undergo medical treatment. If the plaintiff had been willing to go to hospital, it is unlikely that he would have been detained. Similarly, if, whilst in detention, he had asked to be taken to hospital, it seems likely that, in acceding to that request, he would simply be released from detention, rather than being "released into the care of a responsible person". The question whether the hospital constitutes a "responsible person" for the purposes of the Intoxicated Persons Act, although agitated both at trial and on appeal, was a distraction. The arguments may, however, be shortly addressed
30 Section 3 of the Intoxicated Persons Act contained the following definition:
" responsible person includes any person who is capable of taking care of an intoxicated person, including:
(a) a friend or family member, or
(b) an official or member of staff of a government or non-government organisation or facility providing welfare or alcohol or other drug rehabilitation services."
31 Noting that the definition was merely inclusive, her Honour concluded that a hospital would be a "responsible person" for the purposes of the Act. Although it is not necessary to determine whether that view is correct or not, there are reasons to doubt its correctness. First, the purpose of the care envisaged is to limit or avoid the potential consequences of intoxication, rather than to provide treatment for an injury, illness or other disability unrelated to the effect of drugs or alcohol. Secondly, although the examples may well be non-exclusive, each suggests that the person providing the care is an individual, rather than an institution. Even where institutions are envisaged, it is the official or member of staff to whom the intoxicated person is to be released.
32 Even if a hospital were a responsible person, and was prepared to take the plaintiff (as seems likely considering his physical condition), it is clear that there is no power to release a person into such care if he or she is "not willing": s 5(4)(b), second limb. The plaintiff did not go to hospital in the ambulance at 2.30am because he refused assistance. Whether or not the police had power to detain him for the purpose of taking him to a hospital, it is beyond doubt that they had no power to require him to remain in a hospital. If he had maintained the view expressed to the ambulance officers, it is probable that he would have left the hospital, unless the police intervened to take him back to the police station.
33 With respect to the liability of the ambulance officers, accepting that they should have informed the police of the plaintiff's need for medical assessment and accepting that the police would have taken him to hospital, the plaintiff would still have failed to establish liability on the part of the Ambulance Service unless he satisfied the Court that he would have accepted medical assessment and treatment from a hospital. That question was not addressed in terms by the trial judge. Without an affirmative finding on that issue, the claim against the ambulance officers should have failed.
34 This issue was not entirely disregarded in her Honour's reasons. Thus, in considering the assessment of damages by reference to the loss of a chance of a better outcome, her Honour took into account that "even if the plaintiff had been conveyed to hospital there was a chance that his behaviour may or may not have permitted discovery of haematoma at an earlier time": at [109]. That assessment did not, however, purport to address the issue of causation: what needed to be established on the balance of probabilities was that -
