Disputed facts
18I turn now to consider the evidence and submissions with regard to the facts in dispute.
19One disputed fact focussed upon the reliance placed by the defendant on the working relationship between Mr Dearing and Mr Howarth. According to the Agreed Facts, Mr Dearing had worked with another door frame manufacturing company, HowHua Steel Door Frames Pty Ltd (HowHua), for about two years before moving to AMDF. Other evidence revealed that while at HowHua, Mr Dearing had worked with Mr Howarth. The defendants submitted that the longstanding relationship between Mr Dearing and Mr Howarth supported an inference that Mr Howarth had acceded to a request by Mr Dearing to allow him to use the press when he should have refused. It was submitted that it was open to the Court to find that Mr Howarth had a lapse of judgment as a supervisor. The effect of this conduct was said to impact on the defendants' culpability because Mr Howarth's lapse was "hardly foreseeable" by the defendants who believed Mr Dearing was untrained.
20In the Court's view, it is not necessary to draw any inference, if one were available, based on purported evidence of a longstanding relationship between the two men. Apart from the fact that according to the evidence both men had worked at HowHua before commencing work at the defendants' premises, there is no evidence of any "longstanding relationship" between the two, either in a professional or personal capacity. Mr Dearing commenced work at the defendants' premises in September 2009. Mr Howarth did not commence working there until April 2010 after which he supervised Mr Dearing's work on the welding side of the premises.
21The evidence does give rise to a reasonable inference that on the day of the accident, Mr Dearing asked Mr Howarth for permission to go across to the "folding side" of the premises to fold spreader bars. This particular matter was not in dispute, having been conceded by the defendants in written submissions. What remained in dispute was whether Mr Howarth's conduct (in giving permission), operated to minimise the defendants' culpability.
22According to the evidence Mr Howarth was unsure whether Mr Dearing had been shown how to operate the press. He said he did not show Mr Dearing how to operate the press. Nor did he supervise him while he was operating the press. Mr Howarth did not know whether Mr Dearing had received any training or instruction from someone else on how to use the press. In his oral evidence, Mr Howarth appeared uncertain as to whether Mr Dearing had even used the press prior to the accident. When this evidence is considered in combination with Mr Howarth's role as Mr Dearing's supervisor on the day of the offences, as well as the fact that Mr Dearing normally worked on the welding side, not on the folding side of the premises, it is reasonable to conclude that Mr Howarth might have had a momentary lapse of supervision. The significance of this will be given consideration later in these sentencing reasons.
23Another matter in dispute focussed upon the extent of Mr Dearing's training on the press. According to the defendants they were of the belief that Mr Dearing was untrained in its operation. No evidence was forthcoming as to the basis of this belief. There was evidence that Mr Dearing was shown how to operate the press, which could be construed as constituting some "informal training".
24The evidence on this issue was that Mr Dearing said it was "possible" that Russell Townsend, the foreman on the folding side at the time of the accident, had shown him how to use the press. The amount of time Mr Townsend spent on this activity was, "probably five minutes". Mr Townsend on the other hand denied providing any "training" to Mr Dearing on how to operate the press. Mr Dearing said that he operated the press to fold spreader bars when he had nothing else to do. He did not know how to programme the press so someone would set it up for him. In an interview conducted by the WorkCover investigator, Mr Dearing was asked whether he was provided with any information on the safe use of the press at AMDF's premises. He said that he was told, "don't get your hands caught, that's about it". Later in the same interview in response to a question whether he received any instructions on the safe operation of the press, he said, "I was shown how to push the button and take my hands out of the way". In response to a question whether he was trained to use the press, he replied, "I don't think so. I was shown how to use when I need to use it".
25In oral evidence during the hearing, Mr Dearing affirmed that he had used the press to fold spreader bars. He said he did so when he had nothing else to do. He said he always asked someone beforehand (one of the supervisors on the folding side) and they always gave permission. He said that someone always programmed the press for him so he could fold the spreader bars. He also said that at times a supervisor looked over his shoulder while he was using the press to ensure he was using it properly.
26Other workers at the premises at the time of the accident also gave evidence which was largely consistent with the evidence of Mr Dearing as to the extent of the instructions given to him on how to operate the press. Adrian Simpson, for example, a process worker on the welding side, said he was shown how to use "the brake presses" on the folding side by Mr Townsend. In response to a question as to what was the full extent of his training by Mr Townsend on the operation of the brake press, he said:
Yeah, it wasn't really training really, because it was just showing that this is what happens, and this what you do. You put this 40 millimetre width piece of steel or sheath in there, you push the button or the foot peddle, and the blade comes down and then folds it.
27Raymond Brennan, employed by AMDF as its production manager at the time of the accident, said in an interview that he trained AMDF workers how to operate the press. He said the training was informal and consisted of showing the workers how to use it and then observing them in order to assess their competency. No formal records of this procedure were made.
28The conclusion is available from this evidence that Mr Dearing was shown how to use the press by someone, possibly Mr Townsend. Moreover, a supervisor, or supervisors, observed his work to ensure he was operating the press correctly. The extent of any safety instructions issued to Mr Dearing were limited to a verbal caution not to get his hands caught. He was not trained in the start up procedure or how to programme the press in relation to various bending cycles. The training of other employees in relation to the operation of the press was also limited to showing them how to use it in the presence of a supervisor who then observed them operating the press in order to assess their level of competency. No records of this procedure were made.
29Another area of dispute concerned the number of times and the length of time Mr Dearing spent operating the brake press. How this particular issue was said to impact upon the sentencing process was not satisfactorily explained. Nevertheless, the evidence on this issue, in the Court's view, was inconclusive. In his WorkCover interview Mr Dearing said he "could have" used the press 20-30 times. Mr Dearing also said that on the day of the accident he had used the press for, "about an hour or two", or "half an hour to an hour". No other evidence was forthcoming in relation to this issue except for a statement made to the police by Timothy Martin, employed by AMDF as a factory labourer on the folding side at the time of the accident. Mr Martin told police that he recalled Mr Dearing using the press "periodically". He could not recall the length of time Mr Dearing had spent using the press. Mr Howarth's evidence insofar as it impacts on this issue has been earlier referred to. Mr Howarth had been working at AMDF for about two months prior to the accident (April to June 2010). His evidence concerning the number and duration of times Mr Dearing had operated the press during this period was not consistent. In a WorkCover interview, Mr Howarth said that Mr Dearing had operated the press on other occasions prior to the day of the accident. He said that on those occasions, Mr Dearing was folding spreader bars. In a later statement, he said he did not recall whether Mr Dearing had worked on any of the presses at the premises, and, in particular, whether he had operated the press involved in the accident. In oral evidence during these proceedings, Mr Howarth at first said he had seen Mr Dearing operating the press before the day of the accident. Later he said he did not know if Mr Dearing had operated it, although he had seen him folding spreader bars on another press (known as the Adira press).
30Given the state of this evidence, the Court is unable to form a concluded view with regard to the number of times, or the duration of time, Mr Dearing spent operating the brake press involved in the accident.
31In written submissions, the prosecution nominated other matters in dispute, however, having heard the parties in oral submissions it appeared that these matters were no longer in contention. One matter concerned the sequence of events which preceded the accident (described by the prosecution as, "the mechanism by which Mr Dearing suffered the injury"). In his evidence, Mr Dearing outlined the sequence of events immediately preceding the accident:
Q. On the day of the accident, can I just take you to the incident itself, can you just outline the steps that you took in relation to placing the piece of spreader bar on to the die. Do you recall that?
A. Doing that?
Q. Do you recall what happened next?
A. I pushed the pedal down and I dropped the spreader bar the other side and dropped the pedal down.
Q. Can you just explain what happened in terms of the piece of metal falling. Did it fall down the back?
A. Yes it fell down the back of the machine.
Q. What did you try and do?
A. I couldn't try and do anything because by the time I dropped forward and pushed the button the weight on my foot ...
Q. You lent forward and tried to get the piece of metal?
A. No, I didn't. I dropped it and because I lent forward the weight of my foot pushed the button.
Q. Where were your hands at that time?
A. Squashed.
32The prosecution was concerned to rebut any suggestion that might have been advanced on behalf of the defendants that Mr Dearing's accident was a direct consequence of "skylarking" on his part, or because of some deliberate intention to injure himself. No such suggestion, however, was made on the defendants' behalf. In any event, the evidence of Mr Dearing extracted above facilitates a reasonable conclusion that the accident was caused by Mr Dearing's inadvertence in pressing the foot pedal of the brake press.
33A further matter nominated by the prosecutor as being in dispute was described as "the circumstances which led to the TIROPS light curtain guarding system being placed into bypass mode and therefore disabling the guarding system or the SAFAN brake press".
34The evidence in relation to this issue has been touched upon earlier in these sentencing reasons. That evidence concerned the investigations conducted by the police and by WorkCover inspectors after the accident in an attempt to discover how and why the guarding system had been disabled. According to the police, the disabling of the guarding system constituted a deliberate act. Neither investigation was able to detect who might have been responsible, and the workers who operated the machine did not appear to have been aware that the guarding system had been rendered inoperable. Inspector Hughes and Mr Fraser were unable to determine when the system was bypassed, or the precise location of the fault.
35All of this material formed part of the Agreed Facts and was therefore not in dispute. In any event, the defendants, in written submissions, confirmed that there was no issue with regard to the reports of Inspector Hughes and Mr Fraser. Both men were required for cross-examination, and their evidence was described by the defendants as "frank and forthright".
