Jacobs J went on to say (at 447):
'It will generally be found in the case of an employee and it will often be found in the case of a sub-contractor that, though performance of the acts necessary to performance of some statutory duties may properly be delegated to them, the performance of other acts and the compliance with other statutory duties will remain the direct obligation of the employer or the head contractor as the case may be. Whether in any particular case this is so will depend upon the circumstances'.
Earlier, Jacobs J (at 446) dealt with the situation where a person carrying out building work delegates work to a sub-contractor but still has a statutory duty not to expose that sub-contractor to accident risk. His Honour said:
'When an employee is instructed to do building work in circumstances where the employer has a statutory duty to do acts or things in order to ensure their safety when engaged on the building work there must be more than an implication that they will take any necessary preliminary steps in order to ensure that the work which they are instructed to do is done in conditions where under the statutory duty of the employer is fulfilled. An employee must be particularly directed to do the specific work necessary in order to fulfil the employer's statutory duty and must be provided with all material, assistance and supervision necessary to ensure his ability to comply with the statutory duty. A sub-contractor must be under a particular contractual obligation expressed or necessarily to be implied from the nature of the work to carry out the preliminary work necessary to ensure that when he and those under him are engaged in the building work they will be so engaged in conditions which satisfy the statutory duty'.
In my opinion, the reasons for judgment of Mason and Jacobs JJ are not inconsistent with those of Barwick CJ. They can readily be reconciled.
The essential point made by Barwick CJ was that whether a person was obliged to comply with the regulation depended upon whether that person was actually carrying out building work: see Hetherington v Mirvac Pty Limited [1999] NSWSC 443 per Wood CJ at CL.
Mason J held that where a person participates, whether by act or approval, in the building work carried on by the independent contractor to whom the work has been delegated, that person is duty bound by reg 73. There is nothing in this proposition that departs from anything said by Barwick CJ.
Jacobs J pointed out that, where a head contractor instructs some other person to carry out part of the building work, circumstances may arise that require preliminary steps to be taken to ensure that the work which the other person is instructed to do can be done safely. The issue then arises as to the responsibility for those preliminary steps. It must be a question of fact in each case as to whether the other person has been instructed to perform the preliminary steps as well as the work, the subject of the express instructions.
According to Jacobs J, the head contractor will only be regarded as having instructed the other person to perform the preliminary steps if that person was particularly directed to do the specific work 'necessary in order to fulfil the [head contractor's] statutory duty'. That is to say, according to his Honour, the head contractor will only avoid having a statutory duty in regard to the preliminary steps if the head contractor particularly directs the other person to take those steps. Additionally, the other person 'must be provided with all material, assistance and supervision necessary' to ensure compliance with reg 73.
These remarks have to be seen in the context of the statement by Barwick CJ that under the regulations a head contractor owes no duty thereunder in respect of work delegated by it. Jacobs J was merely saying that a court will be slow to hold that instructions to another person to carry out specific work impliedly include instructions to perform the preliminary steps that may be required to make that work safe. His Honour observed that where the express instructions do not cover the preliminary steps, the head contractor may continue to owe statutory duties in regard to the work involved in those steps. Nothing in this approach departs from that of Barwick CJ.
It is not unusual for a head contractor to delegate a specific task to a sub-contractor and to say nothing about the ancillary work or preliminary steps necessary to ensure the safety of those who will be working on the delegated task. In that event, the task of doing the work necessary to complete the ancillary work or preliminary steps may well not be within the work delegated. In such a situation, were the head contractor not to be duty bound to comply with reg 73 in regard to the ancillary work or preliminary steps, there would be a gap in the security net that the regulation is intended to provide. The safety of all involved in the total building enterprise would then not be secured. The strictures expressed by Jacobs J are designed to prevent such a gap from opening. To ensure that the policy of the legislation, as enunciated by Barwick CJ, is fulfilled, the approach of Jacobs J should be adopted."
71 Ipp AJA went on to consider what work Maggiotto did as head contractor, and said at [31]-[39]:
"Maggiotto had only two labourers on the site and their work was cleaning. All structural and construction work, involving all the various trades engaged to construct the 35 units, was being carried out by sub-contractors. This involved the excavation work, the form work and pouring of concrete, the formation of walls and bricklaying, roof trusses and the formation of the roof, and various aspects of carpentry work. Plainly, a great deal of co-ordination and supervision was required. This task was assumed by Maggiotto.
Frank Sgambellone was the Maggiotto foreman on the site. His task, according to his testimony, was 'project management of trades and progress of job'. He said that project management entailed 'virtually control of sub-contractors, purchase ordering, liaising with architects, engineers, Department of Housing'. Maggiotto, through Mr Maggiotto and Sgambellone, in fact gave directions as to when and where the work was to be done. Those persons, on Maggiotto's behalf, supervised and co-ordinated the various activities and trades involved.
In this process of supervision and co-ordination, Sgambellone instructed and permitted the various sub-contractors to go to the various areas where they were working whenever it was appropriate for them to do so.
Sgambellone said that he had a system which he adopted in determining when the fit out carpenter would commence his tasks. The system was to instruct the carpenter to commence his joinery work after the gyprock walls were lined. Sgambellone would, from time to time, as a carpenter would finish his work in one unit, instruct the carpenter to proceed to commence work on another unit. In particular, as regards Gordon, Maggiotto told him where and when to work. Sgambellone accepted that one of his tasks was to provide Gordon with continuity of work until he had completed his tasks. In cross-examination, when asked whether, when he was on site, he was under the direct control of Sgambellone, Gordon said:
'If Mr Maggiotto was not there, yes I'd be under Frank's control'.
It was put to Gordon in cross-examination that Sgambellone, the foreman, 'was the person who provided you with all the materials you needed on site, didn't he'. He replied in the affirmative. Sgambellone agreed with the proposition that Maggiotto supplied the materials with which the various trades on the site 'carried out their various activities'. Thus, it was part of Maggiotto's supervisory and co-ordinating function to supply Gordon with necessary materials. These would include scaffolding, when necessary. In the case of unit 33, scaffolding was patently necessary for the purposes of bridging the void.
Therefore, on the undisputed evidence, Maggiotto co-ordinated and supervised the different trades required for the completion of all the building work on site, and supplied the materials necessary for the trades to carry out their work. In performing these tasks Maggiotto was, in my view, performing building work (and, hence, construction work) within the meaning of the definition in s 3 of the Construction Safety Act .
This case therefore differs from Almeida v Universal Dye Works Pty Ltd [2000] NSWCA 264 (belatedly relied on by counsel for the appellant) where Santow AJA pointed out (at para 143) that the none of the respondents had done any construction work.
Gordon was instructed merely to do the carpentry work at unit 33 and to do so without there being stairs in place. He was not directed to do the specific work necessary to protect himself from the dangers and risks caused by the void. Nor was he supplied with scaffolding or other appropriate material. Additionally, the obligations of co-ordinating and supervising the work remained with Maggiotto, and these obligations had direct relevance to the safety of the work Gordon was instructed to perform. It follows that the performance of Maggiotto's duties under Regulation 73 was not 'wholly delegated' to Gordon. Maggiotto still had to do construction work in regard to unit 33. That work involved co-ordinating and supervising the activities to be performed by Gordon and others, and supplying the necessary materials to Gordon.
There can be no doubt but that Maggiotto breached the duties imposed on it by reg 73."
72 It seems clear that the construction by Ipp AJA of what was said in H C Buckman & Son Pty Ltd v Flanagan was an essential part of the reasoning which led to his conclusion that Gordon's cross-appeal should succeed. Since Meagher and Stein JJA agreed with him, his construction of the High Court case is part of the ratio decidendi of Maggiotto's case and binds this Court.
73 The first submission of the plaintiff was that there were factual similarities between Maggiotto's case and the present case, namely that in both cases the head contractor supplied materials. That similarity exists, but there are three very significant differences. The first difference is that in that case the head contractor had to coordinate and supervise the activities of a large number of tradesmen in constructing from scratch thirty five home units, and act as "project manager"; in this case the activity involved was simply placing cladding on the walls (the windows having been dealt with weeks earlier, and no other trade being involved). The second difference is that in that case the head contractor gave directions as to when, where and in what order the work was to be done, and Gordon admitted that he was under the head contractor's control while in this, according to the findings of the trial judge which are in part unchallenged and in part not successfully challenged, the partners determined for themselves the manner in which they did the work, the hours and days worked, the order in which the work was done and which one did which part of the work; they were not subject to any instruction or directions by the defendant as to how and when they carried out the work, nor to any supervision. The third difference is that in that case the head contractor supplied materials when needed; in this case the head contractor did not supply them until a request was made by the partners. In Maggiotto's case it could be said that the head contractor had an absolute obligation to ensure that materials, including the missing stairs which, had they been there, would have prevented the plaintiff's fall, were there; here the head contractor's only obligation was to supply what was asked for and not until it was asked for.
74 The second submission of the plaintiff was that the scaffolding supplied was inadequate. That is material on the question of whether, if the defendant was bound by Regulation 73, it had complied. But it is an immaterial submission on the present point, namely, whether the defendant was bound. In any event, the trial judge found that the preferred method of working in the area where the plaintiff fell was to remove roof tiles and build a platform across to the moveable scaffolding, but that a satisfactory method was to work from a ladder set up as the plaintiff had his ladder set up, provided that it was securely tied at top and bottom, being held by Peter Gromek for any brief period which was necessary. In short, the ladder used, which the partners (not the defendant) owned and provided, was an adequate item of equipment provided it was properly used.
75 The third submission was that the use of the ladder was "an unsafe and non-complying method". That submission is material to the question whether, if the defendant was bound by Regulation 73, it had complied. But it too was not material to the present question, namely whether Regulation 73 applied to the defendant. See further [83] below.
76 The fourth submission is that the defendant through Andrew Szatow was aware of the method which the partners would use. That was rejected as a matter of fact at [19] above.
77 A fifth submission of the plaintiff turns on the argument that Andrew Szatow visited the site on a number of occasions, instructed the partners how to do various tasks, and received requests from them about how to do them. So far as that argument would assist the plaintiff, it was rejected at [21]-[26] above. There were visits and discussions, but they did not rise to the level of direction, control or supervision.
78 The fourth and fifth submissions, so far as they attempt to fit this case into Mason J's proposition that Regulation 73 applies to a person who "participates, whether by act or approval, in the building work carried on by the independent contractor", thus fail.
79 Sixthly, the plaintiff appeared to rely on an analogy with Maggiotto's case and to say that here, as in that case, there was a delegation only of a specific task to the sub-contractor, but not the ancillary work or preliminary steps necessary to ensure the safety of those working on the delegated task. The plaintiff submitted that the delegation by the defendant was not complete; that the defendant retained the right and duty to supply necessary materials apart from the partners' ladder and tools, and among those necessary materials was scaffolding; and the retention of that right and duty amounted to building work. Even if the partners as independent contractors could do the cladding work as they wished without control from the defendant, the defendant retained a duty and responsibility to supply proper scaffolding. That duty and responsibility stemmed from the fact that the defendant knew the plaintiff was not trained to erect scaffolding, was not qualified to erect it (Construction Safety Act 1912 s 17A(1)), did not own any scaffolding, and had never provided it during the numerous past jobs the partners had done for the defendant; and from the fact that the defendant had always supplied scaffolding when needed for those jobs. The duty further stemmed from the fact that the defendant knew or ought to have known that not only was the plaintiff not a skilled scaffolder, but he also lacked the skill to determine whether scaffolding was needed and what type of scaffolding was needed. His skill in cladding did not establish any skill as a person who could reliably call for appropriate scaffolding. Nor was the latter skill established by the fact that the partners habitually contacted the defendant and asked for scaffolding when they thought they needed it. Finally, it was submitted that even if delegation was attempted, there could be no proper delegation of scaffolding erection to a person not legally authorised to erect it.
80 The last of that group of arguments can be disposed of quickly. It relied on a statement of Brennan J's in Stevens v Brodribb Sawmilling Co Pty Ltd (1986) 160 CLR 16 at 47. He said that the duty to use reasonable care "does not import a duty to retain control of working systems if it is reasonable to engage the services of independent contractors who are competent themselves to control their system of work without supervision by the entrepreneur." That was a statement about the scope of the common law duty of care, and in particular a statement about its scope in circumstances where there is a need for co-ordination of concurrent activity amongst several trades. It was not a statement about whether there was in fact delegation for the purposes of analysing the application of Regulation 73. What would otherwise be a delegation is not rendered the less a delegation because the principal contemplates conduct by the delegate that may be unlawful. In any event it was not demonstrated that the defendant contemplated the unlawful erection of scaffolding to enable work to be carried on at the point from which the plaintiff fell, since the postulated scaffolding and platform to be used for that purpose had never been requested. See further [83] below.
81 The analogy with Maggiotto's case fails, because here the defendant had delegated to the partners the performance of the totality of the relevant task, namely erecting cladding, on condition that if the partners judged it necessary to use scaffolding, they were to request it and the defendant was to supply it. It was for the partners to decide when, in what order and how the cladding was to be erected. While the provision of scaffolding for carrying out part of the work is capable of being analysed as a "preliminary step" or as "ancillary work" necessary to ensure the safety of the partners, the trial judge found that the actual task in the course of which the plaintiff fell did not require the use of scaffolding, but could be carried out on the ladder actually used provided the partners adopted the simple measures of securing it at the top and bottom.
82 Further, even if the fact that a tied ladder was a safe way of working is put aside, as between the partners and the defendant it was the agreed role of the partners to form a judgment about when scaffolding was needed and to ask for it. The partners were qualified to form a judgment about whether scaffolding was needed even though they were not qualified in law to erect it and lacked specific training in erecting it. The scaffolding actually supplied was safe for the purpose for which it was required - work on the side of the house. The partners did not ask for scaffolding in relation to work on the dormer windows. If the only way of doing the work safely was to employ scaffolding fixed to a platform anchored on the roof timbers, then the cause of the plaintiff's injury was non-employment of that scaffolding, and a failure by both plaintiff and defendant to appreciate that scaffolding so used was needed.
83 The plaintiff's reliance on his difficulties, if any, in assessing what means should be employed with a view to carrying out the work on the dormer windows safely is not assisted by his supposed lack of skill in erecting scaffolding and his lack of legal authority to do so. The real question, crucial to the plaintiff's Maggiotto argument, is what his skill was in diagnosing what the problem was and how it should be overcome. That had nothing to do with his lack of qualification to erect scaffolding or his lack of skill in erecting it. The problem must have been obvious to the plaintiff - inability to use the scaffolding on site, inability to stand on the roof, inability to reach the dormer surface unless the ladder angle was 50 degrees. If the inability of the plaintiff to work out a solution to the problem created by the perceived and obvious danger is a crucial factor favouring the conclusion that there was no total delegation, the fact of that inability is a matter on which the plaintiff bore an onus. That fact also would not take the matter far unless the defendant were aware of it. The plaintiff gave no evidence about his own inability to work out a solution to the obvious danger, and there was no other evidence either of that inability or of any belief on the part of the defendant that the plaintiff had that inability. Nor was there any evidence from which it could be inferred that the defendant did realise, or ought to have realised, that the plaintiff had that inability. The opening words of Regulation 73 raise a factual question, not a normative question. The question is not whether in all the circumstances the defendant should have closely examined the question whether the plaintiff was unable to diagnose and solve problems relating to dangerous cladding operations on steep roofs before effecting a full delegation of the cladding construction work and everything connected with it. The question is whether as a matter of fact the defendant effected that delegation. If the defendant had realised that the plaintiff was relevantly unable to work out safe solutions to obvious problems, that might be an evidentiary factor pointing against the likelihood of full delegation. But there is no evidence either of any relevant inability on the part of the plaintiff or of the defendant having perceived that that inability existed.
84 Seventhly, the plaintiff relies on an analogy with Zahner v Andreas Pty Ltd [2001] NSWCA 352 at [35]. That case is distinguishable. The head contractor there found liable for injuries to the plaintiff while he was dismantling scaffolding had overall supervision of numerous activities on site, including responsibility for coordinating work between various sub-contractors (some of whom themselves sub-contracted works) and ensuring site safety (at [33]). Here there was no need for coordination and to assert that the defendant had a responsibility for ensuring site safety is to assume the answer to the question under debate.
