This appears to be acceptance of the approach taken by Mason J in Buckman .
37 As a judge of an intermediate court of appeal, I feel in some difficulty in the light of the above discussion. The High Court has decisively disapproved of the reasoning in Ginty, Ross and Boyle; but has not in terms disapproved of the result of that reasoning. It has cautioned against implying a limit to the availability to a cause of action for breach of statutory duty, but has not in terms disapproved of the limit implied by Mason J in Buckman. The limit referred to by Mason J was in terms a limit applying only to subcontractors; but the effect of the reasoning in Ginty, Ross and Boyle extended to employees. Furthermore Jacobs J in Buckman applied a somewhat similar approach to employees as well as subcontractors.
38 In my opinion, the results of the reasoning in Ginty, Ross and Boyle retain persuasive weight, as does the reasoning of Mason J in Buckman, as accepted through the endorsement of the reasoning of Dawson J in Nicol. Further, in my opinion the reasoning of Mason J can apply to employees as well as subcontractors, as suggested by the judgment of Jacobs J in Buckman.
39 That is, in circumstances where an employer is carrying on building work and, without any fault of the employer, an employee uses a ladder in breach of regulation 80(6), although the employer will be in breach of the statutory duty, this does not necessarily mean that the employee will thereby have a cause of action for damages against the employer. The existence of such a cause of action depends upon an implication which depends in turn on identification of the class of person for whose benefit the statutory duty was imposed. The approach of Mason J in Buckman suggests there may be excluded, from that class, employees whose actions have put the employer in breach, where nothing done or omitted by the employer itself has contributed to the breach.
40 In my opinion, it is appropriate for this Court to take that approach, unless or until it is ruled out by the High Court.
41 In the present case, the only fault of the employer that can be suggested is that it should have appreciated that the appellant might disobey the instructions given and use the ladder unsecured when left alone on the site. This would not be a casual act of negligence or a mistake made in the heat of the moment, from which employers should protect employees, but, on the findings of the primary judge, a deliberate departure from an instruction twice given by the employer. I do not think there is in these circumstances any fault of the employer that could prevent the application of the principle to which I have referred, excluding the appellant from the class of persons for whose benefit the statutory provision was enacted.
42 Even if there were any breach of any other regulation, such as regulation 73, the same considerations would apply. Accordingly, in my opinion, this aspect of the appeal fails.
43 I would add that this principle applies only where fault of the employer is excluded altogether; and that this will never be the case where the employer has breached a duty of care to provide a safe system of work. If an employer has delegated the provision of a safe system to an employee, and that employee fails to achieve a safe system and is thereby injured, the employer will be liable (subject to questions of contributory negligence) because the employer's duty to provide a safe system cannot be delegated and so the employer's independent obligation remains: see Nicol at 625, Andar at [44].
44 Also, the principle does not apply where the employer is a company and the breach of statutory duty occurs because of the act or omission of the company by its managing director, who also happens to be the employee who is injured. In that case, the breach is by the company through its officer, not merely by reason of an act of an employee; and it cannot be said that the employer company is without fault. So although I would take Andar to have approved the dissenting judgment of Mason JA in Shedlezki v. Bronte Bakery Pty. Limited (1970) 72 SR(NSW) 378, I do not see that as excluding the principle I have applied.
