22 B & E Renovations was involved in the business of manufacturing kitchen fittings such as cabinets. The bulk of the kitchen components constructed at the defendant's premises utilised materials such as laminated medium density fibreboard (MDF). That material was supplied in sheets, each measuring 1200mm x 2400mm x 16mm and weighing approximately 29.4kgs each. They were stored on site at the defendant's premises.
23 At the time of the accident involving Mr Marshall there were no shelving facilities for MDF boards at the workplace. As a consequence, the boards were stored by stacking each board vertically against each other and leaning them against a wall.
24 In order to access boards in the middle of the stack, the employees devised a system whereby one of the men would stand at the side of the stacked boards and flip through the boards. The other employee would stand at the end of the stack of boards and would use his hands and body weight to support the boards that were 'flip passed' on by the employee standing at the side.
25 As I understand the system used, as long as the board was not tipped too far past the direct vertical, the bulk of the weight of the board would be taken by the lower edge of the board resting on the ground. Past a certain point, the weight of the boards would be transferred in part to the employee supporting them at the end of the stack.
26 Once the appropriate MDF board had been retrieved from the stack, the employee supporting the boards would push them back into position, leaning the remaining boards back against the wall.
27 It is apparent, in my view, that the system of work utilised to select a sheet of MDF board from the vertical stack was rudimentary at best. This was particularly so where the employees chose to extract a sheet from within the vertical stack rather than the first available - which was the case on 17 February 2004. Given the way in which it was done, such a decision necessitated the gradual transfer of considerable weight to the employee designated to support the 'flip passed' boards. As para [22] above attests, individually, the full sized boards weighed approximately 30kgs each. Taken together, the six or seven boards of MDF Mr Marshall was supporting at the time of his accident translated into a combined weight of considerable force when they fell in the manner they did.
28 When questioned by counsel for the prosecutor how the risk of the MDF boards falling forward was intended to be controlled, Mr Cluff answered:
As they get heavier … you have to counteract the weight and … try and brace yourself more …the heavier it gets you have to push back. The heavier they get you would hold one sheet at an angle like that, after they come over you would have to straighten them all because they get too heavy.
29 Given that description, which I accept, it is not difficult to visualise circumstances where the likelihood of the combined weight of a number of MDF boards reaches a point and an angle where they cannot be safely supported by the employee charged with that task. In such circumstances, the risk to safety is clearly foreseeable.
30 As was stated in Capral at [82], the existence of a reasonably foreseeable risk to safety 'will necessarily result in the offence being more serious in nature'. As such, the starting point for the determination of foreseeability within the context of the objective seriousness of an offence is whether there was 'an obvious or foreseeable risk to safety against which appropriate measures were not taken'. (Lawrenson Diecasting at 476).
31 Further, as stated by the Full Bench in Capral at [94] 'a breach where there was every prospect of serious consequences might be assessed on a different basis to a breach unlikely to have such consequences'.
32 On this issue, counsel for the prosecutor contended that the failures of the defendant as particularised, particularly by reference to the system of supporting the MDF boards in the way Mr Marshall was doing, carried with it a foreseeable risk of serious injury or death. Further, it was submitted, there was a causal connection between Mr Marshall's fatal head injuries and the defendant's unsafe system of work as particularised.
33 I have no difficulty in concluding that the system of work in place in relation to the manner in which the MDF sheets were vertically stacked and manually handled and supported in the way they were at the time of the accident, given the height and cumulative weight of the sheets, created a foreseeable risk to safety that encompassed the prospect of serious consequences for the employee concerned. I am, however, unable to be satisfied beyond reasonable doubt, on the evidence before me, that such serious consequences would, without more, cause fatal head injuries. There are a number of reasons for coming to that view, not least of all reference to Mr Marshall's activities a few days prior to his accident at work as well as the evidence of Professor Hilton.
34 On Saturday, 14 February 2004, some three days before his workplace accident and subsequent death, Mr Marshall was involved in a physical altercation with his daughter's partner. In that encounter, he was punched in and around the face and head on a number of occasions. According to the eye witness account of Mr Drew Darling, Mr Marshall was not knocked out but sustained 'a cut to the bridge of his nose that bled and he had some blood to one side of his head'. In her statement to the Police, Ms Vicki Egan recounted that on Sunday, 15 February 2004, when Mr Marshall visited her, he told her, inter alia, about the circumstances of the fight as follows:
It happened all so quick. I don't know who threw the first punch. One minute I was standing and then I was on the ground. I hit the side of my head.
35 Notwithstanding the above, subsequent reports of Mr Marshall's behaviour and actions following that incident do not suggest he sustained any significant after effects as a result of the punches to his face and head except what could be described as general soreness and grazes on his face.
36 Mr Marshall did not go to work on Monday, 16 February 2004. It would seem he took the day off in order to assist his daughter with a number of matters. He did attend the defendant's workplace later in the day and spoke with Mr Richard Cluff, a fellow employee. According to Mr Cluff:
Paul walked up to me outside the factory and started telling me about what had happened on Saturday night. I saw that Paul had grazes to the left hand side of his face near his left eye and down onto his left cheek. The grazes stretched down the left hand side of his face and nose.
37 Apart from the obvious evidence that something had happened to cause the grazes on Mr Marshall's face, Mr Cluff did not perceive that Mr Marshall was suffering anything more than relatively minor injuries to his face as a result of the assault incident some two days prior.
38 When Mr Marshall turned up for work on Tuesday, 17 February 2004 there is no evidence to suggest he was suffering any ongoing and/or underlying effects arising from the assault he had sustained on Saturday, 14 February 2004.
39 The recounting of the above incident became relevant in these proceedings because of the circumstances surrounding Mr Marshall's workplace accident involving the fatal head injuries he sustained. That is, as earlier stated, the prosecution contended there was a causal connection between Mr Marshall's fatal head injuries and the defendant's unsafe system of work as particularised.
40 In objecting to that proposition, counsel for the defendant acknowledged there was a foreseeable risk of injury in terms of the activity being undertaken by Mr Marshall at the time of the accident. Further, he conceded it was foreseeable there was a risk of serious injury. However, on that point, counsel submitted, the likelihood of serious injury arising given the circumstances of the activity being undertaken was 'relatively slight'.
41 In support of the above submissions, the defendant relied on the evidence of Professor John Hilton. He was put forward by the defendant as an expert witness and no issue was taken to that by the prosecution. Professor Hilton is a consultant in Forensic Medicine including acting in that capacity for Central Sydney Area Health Service.
42 In order to prepare his report, Professor Hilton was provided with a significant amount of documentary material including police and witness statements, medical and post mortem reports as well as Mr Marshall's medical records from Liverpool Hospital.
43 In his report, Professor Hilton expressed, inter alia, the following opinions:
[1] It is reasonably clear from the various descriptions that during the course of the events of 14 February 2004 Mr Marshall may have gone to ground backwards. According to the statement of Egan, Mr Marshall told her he struck the side of his head on the ground. There is ample physical evidence of him having sustained some apparently minor left-sided facial injuries at about that time. The mechanism by which those injuries were sustained would appear to be associated with punches received during the course of a fracas on the evening of 14 February 2004.
By all accounts there is no evidence of Mr Marshall having shown any loss or impairment of consciousness at or subsequent to these events. However this does not preclude him having sustained some injury to the contents of his head (brain, meninges etc) which, after a period of latency caused him some problems whilst at work on Tuesday 17 February 2004.
[2] It is clear that head injury sustained at work caused Mr Marshall's death. This was sustained when he fell backwards and the back of his head impacted on the concrete floor of the workshop. The distance of travel of his head was from about his own height and the force causing this impaction was that of gravity. A number of sheets of MDF were on top of his legs, perhaps extending up to his lower abdomen. It would appear that a substantial proportion of the weight of the MDF sheets was initially taken by the lower edge resting on the ground. However once they started to fall the dynamics of the situation would progressively change and their terminal position was that in part they were being supported by some portions of Mr Marshall's lower body but not enough to sufficiently impair his breathing or circulation. Thus the final resting position of the MDF sheets vis a vis Mr Marshall's body would not be likely to impair his breathing.
[3] I have examined a parcel of sheets of MDF, each sheet measuring 1.2 x 2.4 metres x 16mm thickness. As its name implies, the substance of which the sheets are formed is fairly dense. It has smooth surfaces. I experimented by balancing one sheet on its edge, then slowly moving backwards, so that the sheet tilted towards me whist I supported it with my hands, spread beyond the width of my shoulders and slightly higher than my head. The force exerted by the sheet on my hands increased progressively as I moved backwards and as the centre of gravity of the sheet moved upwards and towards me. This single sheet was easily controlled without much strength required to support it. The effort which would have been required to sustain 5-8 sheets would have been proportionally greater.
...
In summary, it is not possible for me to exclude the existence of some previous intra cranial pathology existing, and perhaps contributing, to Mr Marshall's work associated misadventure. This may be clarified by a review of the x-rays and scans and a more detailed report from the Neurosurgeons. However, there is no doubt that the immediate precipitating cause of Mr Marshall's death was the impaction of his head on the workshop floor, he having fallen backwards.
The possibility of a pre-existing condition in Mr Marshall contributing to the events of 17 February 2004 cannot be excluded. I cannot say beyond reasonable doubt, that Mr Marshall's fall was the result of the MDF he was supporting, although that MDF may have contributed in some way to the outcome of the fall. It is possible that the injuries Mr Marshall sustained to his head on 14 February may have contributed to the incident of 17 February and its outcome. A further possibility is that Mr Marshall sustained some physiological event causing giddiness and/or faintness, moved backwards, overbalanced and fell. I cannot say beyond reasonable doubt that his partially supporting a number of sheets of MDF caused his fatal fall.
44 In cross examination, Professor Hilton reaffirmed that the way in which the sheets of MDF fell towards Mr Marshall as he was supporting them may have contributed in some way to the outcome, that being Mr Marshall's head injury. Additionally, as the above extract from his report reveals, he identifies two other alternative hypotheses that may have caused Mr Marshall to fall in the way he did and sustain the head injuries that resulted in his death.
45 One hypothesis was that Mr Marshall suffered a stand alone physiological event that caused him to suffer giddiness and/or faintness and he subsequently overbalanced and fell to the floor, hitting his head.
46 The second hypothesis Professor Hilton raised was that Mr Marshall was suffering some underlying residual after effects from the fight he had been in on 14 February 2004 and the knocks he sustained to his head. Subsequently, those residual after effects caused him to faint and/or pass out at the time he was supporting the MDF sheets. On that point, it must be noted, there was no direct evidence of any residual after effects following Mr Marshall's assault up to the time of his attendance at work on 17 February 2004.
47 It would be accurate, in my view, to summarise Professor Hilton's evidence in cross examination as being that the two alternative hypotheses raised by him as to a possible cause of Mr Marshall's fall were less likely than that contended for by the prosecution. That is, it was the cumulative weight of the MDF sheets, together with the manner in which they were being supported by Mr Marshall, that caused him to fall backwards and, in doing so, the back of his head impacted with the floor, resulting in his subsequent death.
48 In support of their submission on this point, the prosecution relied on the evidence of Mr Richard Cluff. Mr Cluff was a fellow employee and was working with Mr Marshall at the time of his accident. Not surprisingly, his evidence as to what he observed was important.
49 Mr Cluff provided four statements in relation to his recollection of events on 17 February 2004. Two were given on 17 February 2004, one on 21 June 2004 and a further sworn statement on 27 July this year. Given the number of statements, it is not surprising that some inconsistencies have crept in.
50 At the outset, on 17 February 2004, Mr Cluff perceived no physical problems with Mr Marshall doing as proposed. That is, supporting the MDF sheets as he (Mr Cluff) flipped them towards him. In supporting the MDF sheets flipped over by Mr Cluff, there came a point at about sheet six or seven when things started to go wrong. Mr Cluff observed the sheets being supported by Mr Marshall began to fall outwards. As he explained on 17 February 2004 in his statement to the Police:
[19] I pulled another sheet forward onto the pile that Paul was holding. Each time I pulled a sheet I asked Paul if he was all right and he told he was. It would have been about six sheets maybe seven sheets that Paul was holding when I was sliding the off cut out of the pile. Paul was going to push the sheets back once I got the off cut from the pile. Virtually as I slid the off cut out, the sheets that were being held by Paul began to fall towards the front. I saw it out of the corner of my eye.
[20] By the time I turned around and faced Paul, the sheets were on about a sixty-degree angle falling towards Paul. I didn't really think much at this time only that Paul had to get out of the way. I think I screamed out, "Leave it". Paul wasn't getting out of the way as they were falling. Once the sheets were falling, Paul must have taken about two steps backwards and the sheets were coming down with him. It appeared that Paul couldn't get out of the way in time. It appeared to me that the sheets were pushing him down to the ground. As the sheets got to his chest, that is when Paul went backwards onto the ground. It like they pushed him backwards.
51 In his affidavit of July this year, Mr Cluff elaborated somewhat on the above as follows:
[11] I recollect that when the 6 to 8 sheets of MDF began to fall towards Mr Marshall, he attempted to stop them falling. I remember observing for a split second or so Mr Marshall straining in an attempt to take the weight of the collapsing sheets but without success.
[12] I recollect saying to Mr Marshall "leave it" as he was attempting to stop the sheets from falling.
[13] Mr Marshall then took 2 steps backwards in what appeared to me to be an attempt to get out of the way of the falling sheets. The speed at which the sheets fell however meant that he was unable to do so.
52 What is consistent in the above two statements as well as his statement to WorkCover in June 2004 is that Mr Marshall seemingly attempted to get out of the way by taking a couple of steps backwards. Admittedly, that observation is contained within one inconsistency where Mr Cluff stated on 17 February 2004 that "... the sheets were on a sixty degree angle falling towards Paul ... Paul wasn't getting out of the way as they were falling" whereas in July this year, he deposed that Mr Marshall was "straining, attempting to take the weight of the sheets without success". In both scenarios, Mr Cluff said he called out "Leave it". A further relevant inconsistency on this point is that, in his statement to Ms Speakman of 17 February 2004, he simply says he saw Mr Marshall 'falling backwards. He fell to the ground like a log ...'.
53 When pressed in cross examination, Mr Cluff adhered to his evidence that Mr Marshall had taken a couple of steps backwards rather than fallen 'like a log' as he had first stated on 17 February 2004. By reference to measurements taken, including the length of the sheets and Mr Marshall's height as well as his position after his fall together with the location of the sheets at the time they fell, counsel for the prosecutor contended it was possible to conclude Mr Marshall did take a couple of steps backwards rather than fell 'like a log' - the inference being that if he had fainted and/or become giddy as per Professor Hilton's two other alternative hypotheses, he would not have taken any steps backwards but simply fallen straight down 'like a log'.
54 Professor Hilton's evidence on this point was as follows:
Q. In terms of the evidence of what occurred at the time, you've indicated that it's possible that Mr Marshall sustained some physiological event - absent the altercation, just generally - and moved backwards, overbalanced and fell. If someone does experience giddiness or faintness - and I take it there's a range of different ways in which that can be manifested?
A. Yes.
Q. Someone might collapse on the spot?
A. Yes.
Q. Without moving their feet, effectively?
A. Yes.
