Section 5B of the CLA
68Section 5B states:
"5B General principles
(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."
69The plaintiffs first of all pointed out that the definition of "harm" in Section 5 is very broad and unquestionably covers the death of Mr Rose. I agree.
70The plaintiffs then submitted that the risk was foreseeable and relied on admissions by Dr Coombes to that effect. These are examples:
"Q. He could just become irrational and, in some way, harm Mr Rose. That was a complete and obvious possibility, wasn't it?
A. As you put it." (T 121.48)
"Q. And, in addition, you knew at that time, as we've discussed, his history from Victoria about hallucinations, possibly command and as well as paranoid delusions. Those factors magnified the risk of something untoward happening on that very long journey, didn't it?
A. Had they been present, yes.
Q. And, of course, you never know when they're going to be present do you?
A. No.
Q. And if he had had a depo injection and it had been given the time to work, the chances of that happening would've been vastly reduced?
A. Yes." (T 122.26)
71The plaintiffs next submitted that the risk of harm was not insignificant and that a reasonable person in Dr Coombes' position, a doctor discharging a patient, would have taken precautions to prevent the risk. The precautions would be simple, namely not discharging Mr Pettigrove into Mr Rose's care to be taken on a long and uncertain journey.
72The defendant did not concede any element of Section 5B(1) but concentrated its defence on the foreseeability and significance of the risk and the application of Section 5B(2)(a).
73The defendant's written submissions began with this passage from Hunter Area Health Service v Presland (2005) 63 NSWLR 22:
"There is no reason whatsoever to doubt that persons working in a psychiatric hospital would be applying their best endeavours to the care of those who come to the hospital. From time to time, things go wrong."
74The defendant relied heavily on Presland in particular to emphasise there was no common law duty to detain a psychiatric patient against the patient's will. As I have already mentioned, the difficulty with this submission is that there is no evidence that Mr Pettigrove would not have remained at the hospital without the need for compulsory detention. The distinction in the present case with Presland is that the issue here is not the question of whether to detain or not, but rather whether it was negligent to discharge Mr Pettigrove into Mr Rose's care having regard to the road journey that was to take place.
75I also think the present facts can be distinguished from those authorities, such as Smith v Leurs (1945) 70 CLR 256, where it is said that a duty of care does not normally extend to cover the acts of third parties.
76Once again I think the facts of this case, at least as presented by the plaintiff, have a point of distinction. The third party here is one known to the defendant and being specifically used to perform a service on behalf of the defendant, namely to deliver Mr Pettigrove to Victoria to receive ongoing care. The situation is more akin, on the plaintiffs' reasoning, to a person being asked to transport a dangerous prisoner without precautions being taken to ensure that the prisoner could not harm the person undertaking the carriage.
77Ultimately I think this case comes down to the foreseeability of the harm, the significance of the risk occurring and "the probability that the harm would occur if care were not taken" .
78The defendant referred me to Benic v State of New South Wales [2010] NSWSC 1039 where Garling J conducted a concise analysis of Section 5B. In relation to foreseeability his Honour said the following:
"[90] The first element is that a plaintiff must establish that the risk of harm was foreseeable to the defendant. Foreseeability is described in the statute differently from the common law description. In the Civil Liability Act, s 5B(1)(a) describes a foreseeable risk as a risk of which the defendant knew or ought to have known. A plaintiff must establish either actual knowledge in the defendant of the risk of harm, or else constructive knowledge (ie. the defendant ought to have known) in the defendant of the risk of harm.
[91] The Ipp Report was the source of the provision of the Civil Liability Act under discussion. In para 7.10, the following remarks were made:
Whereas probability is a scientific concept, foreseeability is a matter of knowledge and inference. For instance, no matter how likely it is that something will occur, it is foreseeable by a person only if that person knows or ought to know that it might occur. (Knowledge must be judged as at the date of the alleged negligence and not at a later date; that is, without the benefit of hindsight and ignoring subsequent increases in knowledge about the risk and its consequences.
[92] In my opinion, the plaintiff must satisfy the court that the defendant, at the date of the alleged negligence, knew of the alleged risk of harm, or else, by reference to other facts, matters and circumstances ought to have known it. Those other matters will vary from case to case but may include such things as the common knowledge and experience of others in the similar position of the defendant, public notoriety of a particular risk of harm, publications and academic knowledge which might be expected to be read by people in the defendant's position and the obviousness or the likelihood of the event happening when using common sense."
79I think the view of the experts is significant. The issue is dealt with in Question 7 of the joint report (Exhibit B). Drs Kingswell, Parmegiani, Campbell and Telfer all classified the risk as minor or fanciful. It is noteworthy that Dr Kingswell fell into this category because he was one of the doctors more critical of the discharge. Drs Giuffrida and Phillips did not think the risk was fanciful. Despite Dr Phillips' view on this point he was nevertheless of the opinion that many of his peers would have seen the discharge as being reasonable (T 201.43). This point is perhaps more relevant to the applicability of Section 5O, which I will return to below.
80I also, however, note this evidence from Dr Phillips where he agrees with Dr Campbell that a particular patient's history is important. I interpolate here that there was no history of violence toward others in the whole of Mr Pettigrove's 20 year history of schizophrenia.
"WITNESS PHILLIPS: Jonathon Phillips. I think it would be fair to say, your Honour, that the more acute and active psychotic symptoms a person has the higher the risk of something wrong, something happening which will be potentially dangerous to self or others. However, that has to be taken in the context of the person's longitudinal history and if a person has over a very substantial period of time despite active psychotic features not acted on them, then that will suggest a higher level of safety.
HIS HONOUR: Well, that's Dr Campbell's point about history as an important factor in a decision.
WITNESS PHILLIPS: I believe the longitudinal history is quite critical, not only in this man's case but in any similar case." (T 199.17, emphasis added )
81In Benic Garling J concluded his analysis of Section 5B(1)(b) in this way:
"[101] I will now attempt to draw together this variety of sources to state what approach, in my opinion, is the appropriate one to interpreting the phrase "not insignificant":
(a) The assessment of the risk of harm is one made in prospect and not retrospect. Hindsight has no part to play;
(b) The phrase is of a higher order than the common law test, and this was intended to limit liability being imposed too easily;
(c) The phrase "not insignificant" is intended to refer to the probability of the occurrence of the risk;
(d) In the realm of tort law, the probability of an occurrence is both a quantitative measurement, which may, but does not necessarily reflect a statistical and numerical assessment, and also an evaluative measurement. The statutory phrase is a protean one which depends upon the context of facts, matters and circumstances for its meaning;
(e) Whether a risk is "not insignificant" must be judged from the defendant's perspective and must be judged on a broader base than a mere reductionist mathematical formula."
82Returning to the evidence of the experts, Dr Kingswell, commenting on Mr Pettigrove's history said:
"Mr Pettigrove had a known history of doing odd things when he was unwell - neglecting himself, trying to jump in front of trains and other dangerous behaviours - so misadventure was a clear outcome and it should have been a known one." (T 184.15)
83Dr Parmegiani gave what I thought was this important piece of evidence, which is perhaps as much relevant to causation as foreseeability:
"There is - I can't see the connection between the car trip and in fact because there is no evidence that the car trip played a role either in unsettling him or causing an accident in somehow killing Mr Rose, I just cannot see either a connection between the homicide and the car trip or see the decision to discharge him home via car that was driven by he and his friend alternating as having any bearing on what happened or on the level of care decision making by Dr Coombes.
HIS HONOUR: What you've done is put your finger on one of the main legal issues in the case. But we're not - we're looking at it from a medical point of view. What we're looking at at this point is whether the decision to discharge in the manner that happened and in the knowledge that it involved the long car trip was reasonable.
WITNESS PARMEGIANI: Well, I think the evidence is that that in itself was reasonable because as I said there was no accident and no fitting and no connection between the car trip, apart from being perhaps away from civilisation where he could have been anyway in the state forest or in a hotel room; I cannot see the connection between the homicide, the car trip and the discharge planning ." (T 193.4).
84Thus if Mr Pettigrove had not been released the possibility must exist that the decision to attack or the hallucination may nevertheless have occurred if Mr Rose had visited him later in the day at the hospital. I think the importance of Dr Parmegiani's observation, in relation to foreseeability and the significance of the risk, is that the plaintiffs' case revolves around the act of negligence of Dr Coombes in placing Mr Pettigrove into Mr Rose's care for the car trip. True it is that had the trigger for Mr Pettigrove's attack occurred during visiting hours in the hospital there would have been assistance more readily available but that is a possibility which ignores any evidence about the particular circumstances of what might have occurred. For example, an attack in the ward would probably have been quickly dealt with whereas an assault walking in the gardens may not have enabled a rescue.
85Despite the series of failings that I have outlined above on the part of Dr Coombes and the nursing staff (not showing the notes to Dr Coombes) I have, with regret, reached the conclusion that, in terms of Section 5B, the risk was not foreseeable and was not so significant that a reasonable person would have taken precautions against it. In my view it was not probable that harm would occur if care was not taken.
86This opinion includes the alleged failure to properly medicate Mr Pettigrove. I think it worth noting this observation from Dr Phillips:
"Your Honour, I think it would be fair to say that his experience overnight in the hospital was one of agitation and quite a high state of distress, which is not uncommon in people with a psychotic illness; as darkness comes there are less cues to keep a person focussed, and the trip did start later than was anticipated with an almost inevitable overnight stop somewhere, or worse still driving through the night, and that would have added to the risk of an exacerbation of psychotic symptoms whether or not he had the additional medication." (T 176.25)
87Garling J observed in Benic that "hindsight has no part to play" . The admissions by Dr Coombes, if that is how they are to be regarded, are a result of hindsight and no doubt a product of his regret looking back at the events that followed his discharge of Mr Pettigrove.
88Hindsight perhaps allows for a conclusion that if Mr Pettigrove had not been discharged for another day or two, or if he had been given certain or more medication, the killing would not have occurred. Looked at prospectively, however, and utilising the opinion of the experts, I could not conclude that a reasonable person in Dr Coombes' position would have concluded that there was a not insignificant risk of Mr Pettigrove behaving as he did, with or without extra medication. He certainly would not have concluded that there was any significant probability that the harm would occur.
89As observed by Garling J, the CLA is intended to limit and not expand liability. Thus the burden is greater than existed under the common law.
90I hope it is obvious from this judgment that I have a great deal of sympathy for the plaintiffs and that I have not exempted Dr Coombes from criticism. What I cannot do is to reach a conclusion that when Dr Coombes decided to release Mr Pettigrove into Mr Rose's care that there was a foreseeable risk of the fate that later befell Mr Rose. I think my conclusion, in medical terms, is consistent with the view of the experts, although with the exception of Drs Giuffrida and Kingswell.
91I do not think Mr Pettigrove should have been discharged after only one restless night in hospital and without a proper medication plan having been implemented. That, however, is a very different question to whether the consequences of his discharge made the discharge negligent in terms of Section 5B.
92The plaintiffs must therefore fail.
