However, it is necessary for me to refer to the case of Davey v. Skinner [1] , where it would seem that it was decided that both the builder and independent contractors are bound by the various obligations sought to be imposed by reg. 73. Some weight was placed by the majority of their Honours in this case upon certain dicta by Williams J. in Australian Iron and Steel Ltd. v. Ryan [2] . That case decided that reg. 73 was validly made under a regulation-making power in the Act (s. 22) and that, though only a regulation, persons who were injured by reason of breaches of it had rights of action against the persons who were relevantly bound by the regulation. The appellant in that case was itself carrying out the building work and the respondent was its employee in connexion with that work. No argument was addressed to the question of the meaning of the word "agents" in the regulation. With due respect, I am unable to accept the view that "unlike reg. 31 of the Navigation (Loading and Unloading) Regulations they" (the precautions to be taken) "are imposed on the employer personally and he is therefore under a duty to see that they are observed not only by himself but also by his servants and agents and even by independent contractors" (Davey v. Skinner [3] ). Regulation 73 imposes the obligation, not with respect to employment and so not on an employer as such, but with respect to building work which is being carried on or carried out. I agree with the majority in Davey v. Skinner [4] when their Honours said: "Regulation 73 does not impose its obligations on an employer as such nor does it limit its safety measures to employees as such. Nor does it, for example, refer to a contractor as the person obliged to conform to its provisions. In broad terms it directs its provisions to any person who carries out any building work The obligation rests on the active person, that is the one who carries out the work in actual fact." I agree with the majority, and am unable to accept the contrary view of the minority judgment in that case that reg. 73 is directed to the principal contractor or building owner. Building work is so defined that it does not necessarily refer to the total work to be performed in a building, but the definition is suitably worded to enable each section of work being done, e.g. as "painting, cleaning and signwriting", being regarded as building work so that the obligation to take the specific safety measures are imposed on that person who is carrying on or carrying out that particular work.
