8 One issue relevant to the apportionment exercise was ascertaining what it was that the appellant knew or ought to have known between 1964 and 1968 relevant to the dangers of asbestos.
9 There had been proceedings in the Tribunal, heard by O'Meally P called Williams v BI (Contracting) Pty Ltd & Anor [2004] NSWDDT 19 (DDT 262/2002). Mr P J Snelling was called in those proceedings as a witness for the plaintiff. He had been a manager of BI Spraying Pty Ltd prior to 1962. The company operated from premises in Adelaide that were shared by the appellant company.
10 Mr Snelling's oral evidence showed that he was familiar with the work of the appellant during the time he worked for the related BI company. He said that he had responsibility for spraying work (CB 91). Mr Snelling gave evidence about the mixing and bagging of blue asbestos cement as well as the work practices in the early 1960s when asbestos was sprayed under his supervision.
11 Mr Snelling said that it was his job to insist that the BI workers always wore a face mask in the form of a white cloth over their nose. He said that "unfortunately that would only last about 5 minutes before it became fairly intolerable and as soon as I left the site I knew that they used to take the masks off" (CB 94). The following evidence was given:
Q. Were you told why they should wear such a mask.
A. Yes, I can remember when I first started there John Kurnow gave me a - I think it was either a book or a pamphlet which was by Johns Mansville and it was pointing out the dangers of the asbestos and that they should wear these masks, and John Kurnow said, well, it's up to me to make sure that they continually wear them but he knew and I knew that that was impossible.
Q. What did you believe might occur to a man who was inhaling asbestos.
A. 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.
12 One would have thought that this amply demonstrated relevant actual knowledge of the risks stemming from unprotected exposure to the air-borne asbestos being sprayed. A fortiori in light of earlier evidence from Mr Snelling that it was, "very polluted" around the sprayers, with about 25% of what was being sprayed ending up ultimately on the ground or on the sprayer (CB 93).
13 This evidence was tendered and admitted in the instant proceedings. Its admission is not in dispute in this appeal.
14 Mr Snelling was an available witness if additional oral testimony was required.
15 Also admitted in the tribunal below was an affidavit of Mr Snelling sworn 19 June 2002 and prepared for filing in the Williams proceedings (CB 78-82). It is difficult to see what the affidavit added to Mr Snelling's oral evidence in the Williams proceedings, and this may explain why it may possibly not have been read in those Williams proceedings (see below).
16 Portion of the Snelling affidavit lists a number of other jobs involving the spraying of asbestos by one of the Bradford companies (CB 80B-K). It would appear that this paragraph may be the reason for the appellant pressing in this Court the strange ground of appeal that I am about to explain.
17 At trial in the present proceedings it was counsel for PHR, Mr Rundle, who sought to tender the Snelling affidavit. It was Mr Rundle's understanding at the time that that affidavit had been read in the Williams proceedings. O'Meally P was so informed (CB 67) and this was never disputed by Mr O'Dowd, BI's trial counsel.
18 The affidavit was objected to by Mr O'Dowd on the basis that prior intention to use it had not been notified in accordance with what we were told is the practice in the Tribunal. Since s25(3) requires that the Tribunal give leave for evidence admitted in other proceedings to be received as evidence in the instant proceedings, Mr O'Dowd was entitled to ask his Honour to refuse leave in the exercise of this statutory discretion. Be that as it may, the question of prior notification and/or leave under s25(3) is not the issue raised in the current appeal.
19 The affidavit was admitted (CB 70), followed shortly by the admission of the transcript of Mr Snelling's evidence in the Williams case.
20 The point now taken is that the Snelling affidavit should not have been received into evidence in the instant trial by O'Meally P because, unknown to all concerned at the time, it had not been read or otherwise admitted into evidence in the Williams proceedings.
21 As indicated, it was conceded before O'Meally P that the Snelling affidavit had been admitted into evidence in the Williams proceedings. There was therefore a proper basis for the decision to allow the affidavit to be received into evidence in the instant proceedings, in accordance with s25(3).
22 In this Court the appellant has filed recently sworn affidavits to the effect that recent searches indicate that the Snelling affidavit prepared for use in the Williams proceedings was not in fact read or tendered in those proceedings. In support of a favourable exercise of this Court's discretion to receive those affidavits the appellant argues, with force, that the very fact that the Snelling affidavit was sprung on it without warning means that it ought to be allowed the opportunity to correct later-discovered wrong assumptions about it. It is not suggested that Mr O'Dowd had appeared for the appellant in the Williams proceedings. Even if he had, he might be excused for having no instantaneous recollection as to whether Mr Snelling's oral evidence had been supplemented by the reading of the affifdavit.
23 I would nevertheless refuse leave to rely on this material and would dismiss this ground, for the following reasons:
