20 In my view, the primary facts as found were open on the evidence and they amply supported the conclusions that BI owed a duty of care to persons such as the deceased and breached that duty. There was no basis for distinguishing between BI's own employees and tradesmen employed by others coming later to the site, such as the deceased. The facts showed that there was actual knowledge of a risk of injury that was neither far-fetched nor fanciful.
21 In this Court, BI submitted that Mr Snelling's evidence shows that he did not foresee the risk that mesothelioma (as distinct from other asbestos-related illnesses) might be contracted in consequence of exposure to the BI product. When asked what he believed might occur to a man who was inhaling asbestos, he had said (Blue 106):
Well, at that stage I believed that mesothelioma, as I know it today, I believed then that it was caused by the long asbestos fibres. I had no idea it was the dust that caused the problem. So I didn't really appreciate the real dangers and I certainly wasn't told that death was inevitable, as I now believe.
22 Senior counsel for BI submitted that this shows that the particular risk to which the deceased was exposed was neither foreseen nor foreseeable. But this is to commit the fallacy of requiring foreseeability of the precise risk of injury suffered. Such particularity of foresight is not required. It is sufficient that the defendant foresaw or ought to have foreseen harm of a like kind (see Chapman v Hearse (1961) 106 CLR 112; Mount Isa Mines Ltd v Pusey (1970) 125 CLR 383 at 402; Commonwealth v McLean (1996) 41 NSWLR 389). Identical arguments with reference to different types of asbestos-related diseases were rejected by this Court in Bendix Mintex Pty Ltd v Barnes (1997) 42 NSWLR 307 and Julia Farr Services Inc v Hayes (2003) 24 NSWCCR 138.
23 Duck J amply disclosed his reasoning process in the passages that I have cited. His findings as to duty, breach and causation were supported in the evidence and correct in law.
24 CSR was sued as the manufacturer and supplier of the insulation product that was sprayed in 1964. It is unclear (cf Black 75, J52) whether the case was run on the basis that it had a duty of "after care" requiring it to give warnings later as its knowledge about the risks increased. For my purposes it is sufficient to examine its position as at 1964.
25 Since 1943, CSR had been the managing agent of Australian Blue Asbestos Ltd and the sole distributor of blue asbestos mined at Wittenoom (J17). At the relevant time CSR was supplying blue asbestos in Adelaide to its wholly owned Ingham Companies, which in turn mixed it into the product used as a fire retardant in the store at Elizabeth. By 1961 CSR controlled the two Ingham Companies as wholly owned subsidiaries (J18-25).
26 CSR does not dispute the finding (J16) that it was so involved in the distribution and marketing of the blue asbestos in the business conducted by the Ingham Companies as to place it in the position of a manufacturer and supplier of the product sprayed (see also CSR Ltd v Wren (1997) 44 NSWLR 463, 15 NSWCCR 650). Nor does it dispute that its duty to warn of known dangers could extend in a proper case to the employees of likely recipients of its product (see the discussion in Wren at 689-94 (NSWCCR), a portion of the judgment not reported in the NSWLR).
27 CSR's argument was that it should not have been found under a duty to the deceased having regard to the foreseeability in 1964 of injury stemming from the nature and level of the deceased's exposure (in 1974).
28 In 1959 CSR acquired the controlling interest in BI Holdings Pty Ltd, the holding company of the Bradford family (J26). Through this acquisition CSR acquired a 25% share of BI (Contracting) Pty Ltd, the present appellant. This acquisition and other evidence (see J27) were the basis of the primary judge's finding (J28) that:
CSR Limited… was intimately involved in the business undertaking of [BI]. The evidence adduced may not permit the conclusion that it had a controlling share interest in the South Australian company, but it does permit the conclusion that it was actively involved in its undertaking … [It] was actively engaged in the business of [BI], the spraying company ….
29 The findings of primary fact and the conclusion that CSR was actively involved in BI's undertaking are not in dispute. Since, however, the findings stop short of completely equating the businesses of CSR and BI, the appellants are correct in their submission that the reasoning in CSR Ltd v Wren cannot be used as the basis of treating the knowledge of BI as the knowledge of CSR.
30 Contrary to the appellant's submission, the primary judge made no such elision. He dealt with the appellants separately in considering what each company knew or ought to have known in 1964 about the dangers of crocidolite, relevant to the foreseeability component to the duty of care.
31 As to CSR, his Honour made plain his intention to incorporate by reference the reasons of Beazley JA and Stein JA (with whom Powell JA generally agreed) in CSR Ltd v Wren. The joint judgment in Wren contains an extended discussion about the matters of which CSR was or ought to have been on notice in consequence of literature available to it in 1950-51. CSR's access to the same literature was proved in the instant case.
32 According to the facts found in the present case, CSR knew that its crocidolite was being used in the products distributed from the Ingham premises at Dudley Park in 1963-64 (J11). The material referable to the relationship between CSR, Inghams and BI has already been referred to. CSR may not have controlled BI, but it was actively engaged in its business (J28). It and its Ingham Companies knew the general type of work being done with its product by BI.
33 CSR was found to have known of the dangers of asbestos in 1963-64. Duck J made general reference to the information discussed in Wren's Case as part of the knowledge available to CSR through its library at the relevant time (J28-29). There was material additional to that discussed in Wren in the form of an article published in the British Medical Journal in 1960 which was proved to have been brought that year to the attention of Mr Brown who was head of the building materials division of CSR (Blue 12, Black 56). The article referred to carcinoma of the lung as a serious and well-recognised complication in asbestosis. It also referred to asbestos dust as "most toxic", stating that:
… The amount needed to cause asbestosis is not known so constant vigilance and new preventive methods are needed if this disease is to be abolished. (J29)
34 There was also an article by Margaret Becklake (Blue 38) that demonstrated that the association between asbestos and mesothelioma was known to be probable in the 1950s and definitely established by the early 1960s. This and other evidence negates the argument that exposure to the levels that the deceased was exposed to involved no foreseeable risk of injury according to the law's "undemanding test of foreseeability" qua duty (cf Wyong Shire Council v Shirt (1980) 146 CLR 40 at 44).
35 His Honour summarised his findings against CSR as to duty and breach at J30:
