What caused the fall?
27 What caused Mr King to fall to his death? Was it suicide? There is, of course, no direct evidence. Besides the medical evidence, there were three expert reports from engineers before the Court. One of the authors, Mr Michael Griffiths, gave evidence.
28 From the reports it is possible to have an understanding of the area where the accident occurred. Mr King must have left his bedroom sometime after 12.30 am on 27 December 1994 and entered the verandah on the first floor. None of the doors in the clinic were locked since it is a voluntary and not secure hospital. The verandah has a masonry balustrade 230mm wide and 955mm above the verandah floor. There is a distance of 1.215m from the top of the balustrade to the masonry above.
29 Mr Griffiths knew that the deceased's height was 1.8m, that he was of average build and weighed 80kg. In his view, the height of the balustrade would be approximately 50mm above Mr King's centre of gravity. Mr Griffiths' opinion was that Mr King would not have been able to overbalance while facing outwards at the balustrade if he accidentally walked into the balustrade at moderate speed, or leant on it in a normal resting position. The deceased would have had to undertake a manoeuvre which was enough to cause sufficient of his body mass to move outside the balustrade to pull the rest of him over.
30 The conclusion reached by Mr Griffiths was that Mr King most likely fell from the balcony by 'rotating outward from a standing position adjacent to and facing the balustrade'. He said that Mr King could not have overbalanced by accidentally walking into the balustrade, nor by normal leaning behaviour. Some deliberate action to raise his body and manoeuvre it outward from the balustrade was necessary.
31 In a later report, Mr Griffiths stated that the paint marks and abrasions to Mr King's body were likely to have occurred as he slid past the outer wall of the building. This meant that he was not launched outwards by a fast approach to the balustrade but rather that 'he must have edged over the balustrade gradually to beyond the balance point'.
32 The report of another engineer, Mr Barker of Barker Herle, was tendered although he was not required to attend for cross-examination. His report says that there were six different ways in which a person could fall from the balustrade to the ground below. Four of these were not consistent with the paint on the hands and shirt and the position of abrasions to Mr King's feet and shins. This left the possibility that Mr King was standing facing the balustrade and leant outwards from waist level until he overbalanced. He opined that this was the most likely mechanism.
33 A further expert report of a Mr Tom Gibson was admitted into evidence over objection. The contents of it had been used to cross-examine Mr Griffiths. Mr Gibson chose seven scenarios whereby a person of the deceased's height, weight and presumed height of hip joint, could have overbalanced. Some of these are bizarre but it seems that the intention of the author of the report was to attempt to demonstrate that a person could fall accidentally over the balustrade.
34 In his oral evidence Mr Griffiths stressed that Mr King would have to raise his centre of gravity to be able to go over the top of the balustrade. He accepted that the centre of gravity which he had chosen was not necessarily Mr King's actual centre of gravity, rather the average for a man of his height and build. He consulted anthropometry tables. Mr Griffiths accepted that it would only be necessary for Mr King to elevate himself a couple of inches, such as standing on his toes, to be able to overbalance.
35 Mr Griffiths accepted that his assessment could be 'a bit out' and that he could not make an accurate assessment. This was because a number of variables were involved, including the height of Mr King's hips, which had been assumed. His model was, he said, a very simple one. The essence of his position was that Mr King would have had to generate some energy to raise himself sufficiently to clear the top of the balustrade. At a later point in his evidence, Mr Griffiths referred to the need to expend 'a little bit of energy' to raise oneself to get over the balustrade. Since as little as two inches might be sufficient, he agreed that standing on tip toes might suffice.
36 A number of possible situations were put to the witness. One was whether, that if a person's glasses fell off and he lurched to grab them, would that movement be sufficient to elevate him. He answered in the affirmative saying that 'if someone made the deliberate action to lift up over and look and see where the glasses had gone, then … they would have expended that energy to lift themselves'.
37 Dr Johnson was questioned about the side effects of the medications which Mr King was taking. It appeared that these had been administered around 9 pm on 26 December 1994. Besides the anti-depressant and tranquilliser, Mr King was taking two drugs for blood pressure and hypertension. The drugs could lower Mr King's blood pressure and cause posteral hypertension whereby he could become dizzy or possibly black out.
38 Posteral hypertension could also occur if a person got up suddenly from a lying or sitting position after a lengthy period of time. Blood would pool in the lower limbs causing dizziness.
39 Of the other drugs Mr King was taking, Norvasc, would certainly have the effect of lowering blood pressure. Aprinox acted in a different way and was a diuretic, which could have the effect of causing the need to urinate urgently.
40 Dr Johnson indicated that he was also aware of Mr King's cardiovascular problems including transient ischemic attacks, which is an episode of fleeting dizziness representing a minor stroke. Dr Johnson considered that Mr King was vulnerable to transient ischemic attacks.
41 The doctor was also questioned about Mr King's suicidal tendencies. He thought that Mr King was progressing well in hospital and acknowledged that he was pleased with his progress. Mr King had been forthright in their discussion about suicide and answered that he did not contemplate suicide at Christmas, which Dr Johnson accepted. (Black AB 42) If Dr Johnson had been concerned at the risk of suicide, he could have 'scheduled' Mr King.
42 While Dr Johnson considered Mr King to be a suicide risk, it seems that his concern did not extend to scheduling him or taking any particular steps, other than to have him regularly reviewed by staff. It was, he agreed, a reasonably controlled risk. No particular warnings were given to staff. Indeed, Dr Johnson was cautiously optimistic that Mr King was improving.
Conclusion
43 There are, in my opinion, a number of reasonable hypotheses, inconsistent with suicide, which could have caused Mr King to fall from the first floor verandah of the clinic.
44 Mr King suffered from hypertension and was prone to dizziness. Some of his medications could have exacerbated the situation. Mr King had apparently resumed smoking and, although no cigarettes were found on his body, a lighter was found close to his hand at the bottom of the steps. If he dropped the lighter accidentally over the balustrade, he could have stood on his toes to look over to see if he could see it and overtoppled. Also, his spectacles were close to his body, on one of the steps. He could have lost his glasses over the balcony and, either lurched to catch them, or bent forward over the balustrade to see if he could locate them. Either action could result in overtoppling.
45 I am conscious that the expert engineering evidence indicates that only a very small amount of elevation (around 50mm) was required to increase Mr King's centre of gravity to be able to go over the balustrade. On the evidence, standing on tip toes would be sufficient.
46 Moreover, the medical evidence of Mr King being at risk of suicide is not compelling when one examines Dr Johnson's evidence together with the statements of Mrs King and the two nurses about Mr King's behaviour on 25 and 26 December. If Mr King was contemplating suicide by throwing himself off the verandah, it seems somewhat strange since there was no certainty that he would succeed, bearing in mind the distance of the fall being only 4.3m. Also, if Mr King was contemplating suicide by these means, why would he take his spectacles or cigarette lighter?
47 I am driven to conclude that the appellant has not satisfied the onus of proof upon it in order to be able to rely on the policy exclusion.
48 The District Court decision was correct notwithstanding the acknowledged errors. Accordingly, the appeal should be dismissed with costs.
