[59] I would also concur with the observations of Wright J, President, in Ferguson v Nelmac Pty Limited (1999) 92 IR 188 where, in the context of a s15 prosecution, his Honour observed that the Act imposed (at 209):
... an obligation on an employer which is not confined to the taking of precautions only when there are warnings or signals of danger or when experience indicates that a risk to safety has arisen and requires remedy. So much is clear from the structure and language of the section which is premised on the requirement to 'ensure ... health, safety and welfare at work' and the decided cases which make plain the nature of the obligation.
44 Whilst made in the context of proceedings brought under s19 of the Occupational Health and Safety Act, it is relevant to refer to the observations of the Full Court of Fisher P, Glynn and Hill JJ in WorkCover Authority of New South Wales (Insp. Gordon) v Wallis (unreported, Matter No. CT 1011 of 1995, 14 August 1995) (at 9):
The appropriate sections under which to bring charges for failing to provide and maintain a safe system of work and/or conduct an undertaking so as to "ensure" that employees, and other persons at the place of work of the employer are not exposed to risks, are ss 15 and 16 respectively. Such charges must be against the employer concerned. Additionally, under s 50, if an employer corporation contravenes any provision of the statute then each director of the corporation and each person concerned in the management thereof is, subject to the provisions of that section, deemed to have committed the same contravention. But, under the Act, there is no duty cast upon an "employee" while at work, to ensure the health and safety of persons at his place of work by, for example, providing and maintaining plant and systems of work that are safe and without risks to health. (emphasis in original).
45 Their Honours continued (at 11):
In our view the fact that an act or omission of an employee while at work occurs in or in relation to the employer's system of work (or lack of one) or conduct of the undertaking does not of itself exculpate the employee from the duty under s 19(a) to take reasonable care not to do or fail to do any act which may affect the health and safety of any person who is at his place of work. … But, irrespective of the duty to co-operate with the employer and/or of the safety or otherwise of the plant and/or system of work operated by an employer, an employee must nevertheless take reasonable care that his own acts or omissions at work do not affect the health and safety of other persons. Sections 15 and 16 and s 19 are complementary and not mutually exclusive. An exemplary case would be where the employer has in fact instituted a safe system of work and has put in place proper rules and procedures governing its operation and has employed apparently competent and experienced supervisors to police the implementation and application of those rules and procedures. If, in those circumstances, one of the supervisory employees failed to take reasonable care in performing those duties and, by a careless act or omission in relation thereto, endangered the health and safety of other persons at work, then the employee/supervisor may, in our view, be liable under s 19(a). On the other hand a supervisory employee would not, in general and without more, be so liable if the act or omission complained of was, in truth and substance, a failure to provide and maintain a safe system of work or otherwise "ensure" the health and safety of employees under s 15; and a similar position would obtain in respect of what was, in substance, a failure under s 16 to ensure that persons not in employment were not exposed to risks while at an employer's place of work. The acts or omissions in such cases would be those of the employer concerned . (emphasis added).
46 Cases such as the present also demonstrate the necessity for the Court to pay particular attention to the charge that has been brought against a defendant. In these proceedings, the charges against the respondent alleged "a failure to provide a safe system of work for the pouring of concrete into a formed up column", particularised as involving a failure to provide a system of work to prevent the potential for fall injury from an elevated platform, the provision of appropriate plant and equipment to prevent such fall injury and necessary instruction regarding a safe system of work to employees engaged in the pouring of concrete on the day of the accident. The alleged failures are limited to the day on which the accident occurred.
47 The Chief Industrial Magistrate considered that, subject to the s53 defence, an offence had been made out. This was not the subject of appeal, and I consider that such a finding was correct in the circumstances of the present case when considered in the light of the charges levelled against the respondent. Indeed, Mr B D Hodgkinson of senior counsel, who appeared with Ms L A Clegg of counsel for the respondent in these proceedings, conceded as much in his submissions. It is then strictly unnecessary to provide any further consideration as to the commission of the offences. However, it is important to further analyse the culpability of the respondent, as these findings are essential to the consideration of the s53 defence and illustrate the way in which the defence under s53 should have been considered in this matter. I shall return to this point after consideration of the relevant authorities.
48 The submissions for both parties before the Chief Industrial Magistrate relied upon the judgments in Cullen v State Rail Authority of New South Wales (1989) 31 IR 207. In particular, the submissions of the respondent before the Chief Industrial Magistrate relied upon the minority judgment of Fisher P, for the proposition that it was not guilty of an offence under the Act. It was contended that his Honour's minority judgment was referred to with approval by the Full Bench of the Industrial Relations Commission in Court Session in State Rail Authority v Dawson. When stated without more, in my view, this is not an entirely accurate description of the way in which the former President's judgment in Cullen v State Rail was treated by the Full Bench in State Rail v Dawson. It will be, therefore, necessary to consider initially the judgment in Cullen v State Rail in some detail.
49 The circumstances in Cullen v State Rail Authority, whilst tragic, may be fairly shortly stated. A gang of workers employed by the defendant authority as 'linesmen' were performing routine maintenance work, cutting back tree growth which was encroaching an inappropriate distance from high voltage powerlines which supplied the defendant's rail network. The work was being conducted during inclement weather at a location near the Mt Kuring-gai rail station. Two members of the gang, Mr Harvey (the supervisor of the gang) and Mr Baillache, in breach of well established and promoted safety policies and procedures put in place by the defendant, climbed a tree (as opposed to using a ladder or other approved method) to remove a branch which extended to some 50cm from a high voltage conductor. The branch was apparently about the size of a man's wrist. Having been handed a 'bush saw' by Mr Baillache, Mr Harvey proceeded to saw through the branch. The branch, still being attached to the tree by a 'finger' of bark, began to fall. In doing so it came into contact with the powerlines, electrocuting the two men in the tree - Mr Harvey suffering fatal injuries.
50 In the proceedings which followed, the Chief Industrial Magistrate found the offence had been made out, but that the defendant was able to avail itself of a defence under s53(a) of the Act. In his Worship's view, the defendant had developed a safe system of work which had been implemented over a long period, producing a good safety record. The persons engaged to perform the relevant work were well experienced, properly trained and were aware of the policies and procedures in place. His Worship considered, given the nature of the work and the experience of the persons engaged, it could not be said that further supervision would have assisted the provision of a safe workplace. The accident had occurred due to the neglect of the individual employees involved and that neglect could not be sheeted home to the defendant to render them liable to an offence under the Act - it had done, it was found, all that was reasonably practicable.
51 On appeal, Fisher P in a minority judgment, agreed, by and large, with the Magistrate. His Honour set out the circumstances surrounding the accident, including that Mr Harvey, the deceased, was the senior man in the gang, that he was well trained and experienced in the system adopted by the defendant and that the system was found in a book of regulations known as the "Mains Section Standing Instruction". This included a requirement that "work should not be performed on location when any part of the body or equipment came within 5 feet of any exposed high voltage conductor". Various techniques were used to control the fall of branches, none of which had been utilised at the time of the accident. Importantly, his Honour noted (at 208):
As part of the system of work there appears little dispute that where the senior linesman had any reason for considering that there would be a risk of contact between the limb and the conductor that he could call for an "outage" which meant that by arrangement, on an appropriate occasion, power was removed from the conductor enabling the work to be done with safety. The deceased, the senior linesman on this occasion, could have but did not call for an outage.
52 His Honour set out the relevant provision of the Act and continued (at 209):
The Magistrate's finding was that there had been a failure by the employer to maintain the workplace in a condition that was safe and without risk to health.
What was the failure? The failure, extensively debated before us, was submitted as a failure to maintain a safe system of work. However, the evidence was that these elements related to a safe system of work which had been in place for very many years. No evidence was called of previous failures. It was also extensively argued on appeal that in some way there was a failure either to supervise adequately or to employ suitably trained personnel. I consider that on the evidence of both qualifications and experience of the deceased employee, including his leading hand status, the fact that he had qualified by training and examination as a linesman and his familiarity over several years working in the several classifications employed in the work makes it unlikely that a case alleging failure to provide a safe system of work or to require that the work be adequately supervised could possibly have been made out. This agrees with the Magistrate's findings.
53 His Honour emphasised the need to demonstrate a failure on the part of an employer and recognised that the absolute duty cast on employers under the Act was different to that case by the common law (referring to Carrington Slipways Pty Ltd v Callaghan (1985) 11 IR 467). Fisher P then made the following observations on the system then in place (at 209 - 210):
As is common in these cases, the evidence relied upon to demonstrate such a failure was substantially the evidence that emerges from the events themselves. To be safe, the system of work being utilised would appear to require an election between alternatives - if the limb to be severed reached within 1.5 metres of the power line, then the person in charge, here Mr Harvey, should have required a power outage, the existence and availability of which was undoubtedly part of the system within which he worked and was well known to him. In the alternative, if the movement of the limb was such that upon severance it might reach towards the power lines, then such a circumstance should have been controlled by the use of the equipment, including ropes and ladders with which the parties were supplied for that very reason.
…
The evidence strongly suggests that a well known safe system of work was not followed. Mr Harvey, in his familiarity with his employment, may well have taken a short cut in breach of what he had been taught about safe systems and exposed himself to the risks of an inadvertent contact between the severed limb and the power line. Such an observation would account for all the relevant events of the day.
