When reg 122(5) is read in this way, it remains necessary for the maximum loan to be determined "by and in conformity with these Regulations".
128 Mr Gormly and Mr King, on behalf of the plaintiffs, relied on the following exchange that occurred at trial:
"Her Honour: Yes, … just one matter. Is it common ground that the rated lifting capacity was 500 kgs?
Gormly: Yes, your Honour, as far as my understanding of it is.
Einfeld: There is evidence that's been tendered through Mr Luland to that effect, and I won't be adducing any contrary evidence to that fact, if that answers your Honour's questions.
Her Honour: But you're not prepared to say yes to my question?
Einfeld: That's correct.
Her Honour: I noted that statement by Mr Luland and if it was going to be an issue I was going to ask him the basis for it. But if there's not going to be any evidence to the contrary then I won't bother.
Einfeld: I won't be adducing any - if your Honour pleases.
129 Thus, although Mr Einfeld did not accept that it was common ground that "the rated lifting capacity was 500 kgs", he informed the judge that there was evidence "to that effect" and said that he was not tendering evidence to the contrary.
130 The evidence in question was as follows. Mr Patrick Sahyoun admitted that "the weight restriction on the hoist" was 500 kgs and Mr John Sahyoun admitted that the "load limit" of the hoist was 500 kgs. Inspector Luland described the hoist as a "500 kg four section builder's material hoist". Mr Kozianski, the expert witness, described the hoist in similar terms.
131 The judge decided the issue as to whether 500 kgs was the maximum load determined by and in conformity with the Regulations as follows:
"As to reg 122(5), whilst the defendants accepted that the hoist was subject to a load rating of 500 kg, they relied upon the fact that there was no evidence as to its source or basis in particular as to whether it was determined by or in conformity with the Regulations. The plaintiffs relied upon Mr Luland's evidence, the defendants' concessions in this case and in the Statement of Agreed Facts (Ex O, para 10) that the hoist had a rated lift capacity of 500 kgs. The rated capacity was never an issue in [this] case and whilst it would be true to say that the actual source of the rating was not identified, in my view the proper inference to be drawn is that it was determined in conformity with Regulations, particularly in the absence of any evidence to the contrary from the defendants."
132 On appeal, Mr Einfeld did not dispute that the defendants had accepted at trial that "the hoist was subject to a load rating of 500 kgs" and he did not challenge the evidence of Mr Luland, Mr Patrick Sahyoun and Mr John Sahyoun, to which I have referred. He submitted, however, that none of that evidence established that the weight of 500 kgs was a load "determined by and in conformity with these Regulations as a 'limiting load' within the meaning of reg 122(5)". Furthermore, he submitted, the Regulations did not provide for a mechanism whereby a load could be determined and, accordingly, no load was established "by … these Regulations" and no load could have been established "in conformity with these Regulations as a limiting load". He submitted, in effect, that because of the absence of any provision in the Regulations as to an appropriate mechanism of determining the load, reg 122(5) was of no force.
133 Mr Gormly accepted that at the trial the defendants did not concede that the expression "rated lifting capacity" was the same as a load determined by or in accordance with the Regulations. He accepted that "there was never any discussion about that". Mr King took a similar position.
134 On my understanding of what occurred, the plaintiffs simply assumed from the way in which the defendants conducted the trial that they accepted that 500 kgs was the load determined in accordance with the Regulations. But, at least by the time that Mr Einfeld concluded his closing address, that assumption could not reasonably have been made. In the course of his closing address Mr Einfeld said:
"I'll say one more thing about the tile load. It's important. Evidence has been given about the rated capacity of this hoist. Nobody has told your Honour what that means. Nobody has ever actually produced a document identifying or certifying or indicating the statutory or regulatory source of this rating, whether it's part of some guide or some Australian Standard, whether it's compulsory or advisory. We just do not know, and the plaintiffs have called no evidence about it.
We know - and it's been described by Mr Luland for one - as a something or rather technology brand name 500 kilogram hoist, and you now have plenty of evidence that it was rated to carry 500 kgs. No one has told us what that means. Does it mean that that's the guide for this type of hoist, so that there's no offence of any kind, no breach of any regulation, if it exceeds that limit? We just do not know. Everyone has assumed it but it's not there in the evidence. We don't know and we've not been told. The plaintiffs have not established it." (Black 465 to 466)
135 None of the other parties sought to reopen in consequence of these submissions and advanced no further arguments on the point. No objections were made to Mr Einfeld putting the defendants' case on this basis.
136 The judge well understood the defendants' argument on the issue. She observed, as I have mentioned, that the defendants relied upon the absence of evidence as to the source of the load being rated at 500 kgs and, in particular, "as to whether it was determined by or in conformity with the Regulations". Her Honour dealt with the issue merely by observing that while the actual source of that rating was not identified, the proper inference to be drawn from the evidence was that it was determined in conformity with the Regulations.
137 This approach, however, does not overcome the argument that the Regulations, themselves, do not establish a limiting load for the purposes of reg 122(5) and, moreover, provide no means for the determination of a limiting load "in conformity with these Regulations". This argument raises a question of law, not one of fact. It cannot be resolved by evidence.
138 Mr Gormly submitted that the trial judge was entitled to draw the inference that 500 kgs was the weight determined in accordance with the Regulations as there was "some evidence" to this effect and no contrary evidence was adduced. Mr King's submission was that, having regard to what Mr Einfeld said to the trial judge in the passage I have quoted, as well as the other evidence on the issue, her Honour's conclusion was open to her and "should not be seen to be wrong". These submissions do not, however, address the legal question raised by the defendants' argument.
139 Neither Mr Gormly nor Mr King was able to point to any provision in the Regulations that amounted to a mechanism for determining a "limiting load" as this expression is used in regs 122(5) and (7).
140 Mr King submitted that persons with engineering knowledge possibly could understand the Regulations as a whole in a way different to how lawyers or laymen would understand them. For that reason, he submitted, the unchallenged evidence that the "safe working load" was 500 kgs, coupled with Mr Einfeld's concessions at trial to which I have referred, entitled her Honour to find that the weight of 500 kgs had been determined by the Regulations and was in conformity with them. In my view, however, neither the evidence nor the way in which Mr Einfeld conducted the trial can be regarded as proof that a load of 500 kgs was determined by or in conformity with the Regulations.
141 GIO General sought to obtain assistance from a guide put out by the Department of Industrial Relations and Employment, referred to as "A Guide for Riggers". The Guide, however, is what it purports to be, namely, a set of guidelines. It has no statutory force. Accordingly, it does not assist in establishing how one is to determine a limiting load in accordance with the Regulations. That has to be found in the Regulations themselves.
142 In my opinion, therefore, Truss DCJ erred in finding that 500 kgs was a load determined by and in conformity with the Regulations. The Regulations do not stipulate a limiting load for the purposes of reg 122(5) or reg 122(7) and do not provide a mechanism for determining such a limiting load. Therefore, it cannot be said that the defendants committed a breach of either reg 122(5) or reg 122(7).
