Union approval was received and the hearing conservation programme has now started. The interest already shown by the staff and daily-paid employees indicates that it may be successful. To maintain that interest continued support must be given to all aspects of the programme. If noise measurements reveal sources of intense noise that noise must be reduced if it is demonstrably possible to do so. It must be evident to the employees that everything possible has been done and will be done to control Noise. Also, if they are to play their part in a hearing conservation programme, it is not sufficient merely to provide them with hearing protection. A vigorous long-range and detailed educational programme promoted and fully supported by management and applied at all levels must be maintained to stimulate awareness of the hazard, to promote the use of ear protection, and to encourage voluntary attendance for routine audiometry. Education will be the key factor in deciding whether the hearing conservation programme will be successful." [emphasis added]
49 Mr Jones' evidence in his affidavit of 12 October 2002 was that "No hearing protection was provided when I first started" but that "in about 1975/1976 I commenced using cottonwool in my ears to see if that would quieten the noise in the area where I worked". It was "approximately twelve months after I commenced using the cottonwool [that] I was provided with ear plugs which I consistently wore after that time, however I was regularly required to remove the ear plugs in order to communicate".
50 His evidence goes on that "I did try wearing ear muffs after the ear plugs became available however I found that when I turned my head the ear muff would not be touching the side of my head and therefore would open up and allow further noise in".
51 Moreover, he stated that "during the course of my work I was required to listen to the work in order to avoid any dangers".
52 Finally, he stated, "I was not provided with regular hearing tests however the Defendant did test my hearing in May 1973, November 1987 and December 1987".
53 It will be apparent that that evidence is at odds with the position described by Dr Cumpston earlier quoted, to the effect that toward 1967 neckband-style ear muffs were introduced. This was not only for the shaft sinking crews but in all other sections of the mine and that "ear muffs or ear plugs are now freely available for all exposure to noise levels above 90 dbA" and that "the neckband style ear muffs had been well received".
54 First, Mr Jones says to the contrary that not only was no hearing protection provided when he first started at the mine but that around 1977/ 1978 he was provided with ear plugs; he did try wearing ear muffs after the ear plugs became available, though with unsatisfactory result in terms of letting through the noise when he turned his head.
55 In cross-examination he said that it was some ten years after he started that he first began using cottonwool, that is to say around 1974, and his earlier evidence that it was a year later that he started using ear plugs, that is in 1975; see T, 15/08/03 24.5-.12.
56 In cross-examination Mr Jones agreed that his recollection of whether ear muffs were freely available in the late 1960's was affected by the fact that it was "just too long ago"; T, 15/08/03 at 32.1-.37.
57 I refer to this evidence simply to demonstrate that Dr Cumpston's availability could well have been material in respect of the period from 1964 to 1973. But that just emphasises the fundamental difficulty in the claimant's case, were it pressed in relation to that earlier period. It explains why the claimant has pressed his claim much more strongly with respect to the later period. Given that Dr Cumpston was in fact alive until 2001, the loss of his availability only after that reinforces the significant prejudice to the opponent were it open to the claimant to obtain an extension of the limitation period to encompass the period prior to 1974.
58 However, to the extent the earlier period of employment remains relevant, as the opponent submitted, while Dr Cumpston might not have been the only person involved in noise and hearing loss issues at the mine, or even the most involved, at the very least he was the person who most clearly emerges from the remaining documentation as having had significant involvement in the system of work between 1961 and 1968 (with absence during October 1962 to the latter part of 1964). Moreover, he retained an interest in noise issues at the mine even after that up to 1973. For example, in addition to publishing the 1968 article noted above, Dr Cumpston advised the Broken Hill Mining Managers Association (MMA) on industrial deafness issues, and represented the MMA on numerous occasions at conferences from at least 1967 to 1973 at which he made reports and gave talks on industrial noise and hearing protection (see, for example, Mine Managers' Association Minutes 1969, 1972, 1973 [Vol 1, Tab 23]; MMA Industrial Accident Prevention Committee Minutes 1967 [Vol 3, np]; Report of Conference 16 Nov 1967 [Vol 3, np]). In April 1973, Dr Cumpston represented the MMA on the committee drawing up the Australian Standard, which was published in 1976. Thus, it was clearly open to the primary judge to find that the opponent would be placed in a position of significant prejudice by reason of the death of Dr Cumpston.
59 A further ground argued by the claimant is that the evidence established that there were people available who could give evidence as to the system of work, such as other workmen working alongside or near the claimant and supervisors, it being contended that "the evidence established that such workmen and supervisors were available to give evidence".
60 On this, the evidence does not bear out this contention. Mr Cosman, the claimant's foreman in 1968, is now dead; Judgment at [6]. Likewise the claimant's supervisor, Mr Turner, is also deceased; Judgment [15]-[16].
61 The primary judge likewise observed that in respect of other foremen, the claimant had conceded that some were dead and the rest "if alive, would be very old"; Judgment [5]-[6].
62 The claimant in response relies upon an argument with the following steps:
(a) in Brisbane South (supra) Toohey and Gummow JJ (at 547) adopted a passage from Gowans J in Cowie v State Electricity Commission of Victoria [1964] VR 788 to the effect that: " It is for the respondent to place in evidence sufficient facts to lead the Court to the view that prejudice would be occasioned and it is then for the applicant to show that these facts do not amount to material prejudice "; see also Kirby J in Brisbane South at 566;
(b) reliance is then placed on an affidavit dated 2 March 2005, sworn by Steven Akerman from the firm of solicitors acting for not only Mr Jones but also Mr Robertson and who has filed an essentially identical affidavit in both proceedings. I interpolate that objection was taken to the admission of that material as fresh evidence. The affidavit was directed to whether, based on transcripts of cross-examinations which post-dated the judgments in Jones (26 September 2003) and Robertson (22 October 2003), there had been admissions in other industrial deafness matters. The claimed admissions were to the effect that the relevant opponent did have statements from relevant witnesses concerning the relevant working conditions; these were nonetheless statements for which privilege was still claimed by the opponent. Thus the claimant contends that this claim of privilege demonstrated the opponent's failure to satisfy the evidentiary onus referred to in (a) above.
63 This Court deferred ruling upon the admissibility of that affidavit. It had before it in response also an affidavit of Mr O'Donnell from Cutler Hughes Harris on behalf of the opponent dated 20 June 2005 although that affidavit was filed in the Robertson appeal, Cutler Hughes Harris have acted throughout for both opponents. That latter affidavit took issue with the potential relevance of this material, derived as it was from several other cases referred to at para 5 thereof, namely Pearce v The Zinc Corporation Pty Ltd, 29 February 2000 and 1 and 2 March 2000, Pearce v Hamersley Resources Ltd 18 and 25 June 2004. Reference was also made to Stackpool v NBH Limited and Charnock v Hamersley Resources Ltd 16 June 2004.
64 The opponent's objection to the admission of this evidence had two prongs. First, it was alleged that this evidence was not, or was unlikely to be, relevant. Second, it was contended that Mr Akerman was on notice of the relevant material and failed to seek it, well before the decisions in Jones and Robertson. This was said to be by reason of the bills of costs in the possession of, and available to, Mr Akerman for at least twenty-one months prior to the hearing before Rein DCJ in Robertson on 26 October 2003; see attachment to Mr O'Donnell's affidavit.
65 Taking first the question of relevance or potential relevance, while the opponent was careful not to waive privilege or purport to indicate what the material in the witness statements, which had been given in the other matters, might say, the proceedings in Pearce and Charnock were for extensions of time in relation to a similar workplace injury which had been unsuccessful. That certainly undermined their potential relevance. As to the third matter, Stackpool v NBH Limited, while those proceedings for extension were successful, they related to an entirely different albeit adjoining mine, managed and owned by a different company, Broken Hill North. Thus on any view Stackpool could not be relevant.
66 The second prong of the attack relates to the contention that it was only as a result of cross-examination in the matters of Pearce, Stackpool, and Charnock that Mr Akerman "became aware for the first time of the fact that the opponent in these proceedings had available to it statements from numerous persons", being the statements over which privilege was claimed.
67 The answer given by Mr O'Donnell in his affidavit of 20 June 2005 was that, for at least twenty-one months prior to 26 October 2003, by virtue of the Bills of Costs in documents obtained at that earlier date on subpoena, Mr Akerman was on notice of this material well before the hearings in Jones and Robertson. The relevant Bill of Costs at page 7 related to the Pearce matter and thus the relevant mine. They are attached to an application for assessment of costs filed in the Common Law Division of this Court. Mr Pearce sought an extension of time to bring proceedings relating to claims for damages for industrial deafness suffered before 30 June 1987. The application refers to a period of employment by The Zinc Corporation Limited between 1950 and 1968 and by New Broken Hill Consolidated Limited between 1968 and 1991, in circumstances where the workers' compensation liability of both of these companies had been assumed by Pasminco Australia Limited.
68 At page 30 of the affidavit reference is made to an item numbered 39 under the date 24 January 2000 "reading and considering files obtained by Aspec Holdings in searches of client records for general safety matters and particularly hearing protection - 240 pages - 1 hour 40 minutes".
69 It is clear that Aspec Holdings was an investigator appointed by the relevant company. The immediately preceding entry in the Bill of Costs refers to "telephone attendance on Mr Katz of Aspec Holdings regarding his searches of client records …".
70 There is a later entry in the same Bill of Costs dated 3 February 2000 "reading and considering further report of Aspec Holdings on interview with former safety officers and supervisors …"
71 In all the circumstances, I consider that the further material sought to be introduced by the claimant relating to the three matters I have referred to should not be allowed. This is more particularly given the evident prejudice to the opponent from its introduction now rather than at the time of trial, and where its relevance has been put significantly in question.
72 That leads to the ultimate question of whether the primary judge was in error in declining to extend the limitation period in relation to the later period, in particular after 1973. The position before 1973 is self-evidently such that no extension could be justified under the criteria in s60G.
73 While it appears that the opponent has available still a limited amount of documentary material, I would accept that the opponent would be at a significant disadvantage in the presentation of evidence at a trial. This is unless it could bring forward relevant supervisors, foremen or managers from the years 1964 to 1987 to attest to the correctness of the documents in fact, and as to the application of the practices referred to in the documents. The claimant himself conceded in evidence that his foreman over the years would now either be dead or very old. Commonsense suggests that the foreman who would now be very old would be unlikely to give cogent evidence on what equipment, practices and procedures were available and in force between 1964 and 1987.
74 I consider that the primary judge correctly found that the opponent's ability to call evidence on "important factual issues" had been very significantly compromised by the passage of time. That compromise was exacerbated by the change in attitude which occurred when the Pasminco Group went into administration. The administrators of Pasminco simply declined responsibility for any events which occurred prior to Pasminco coming into existence (about 1988). Moreover, the administration of Pasminco occurred nearly three years after the claimant became aware of his rights and that delay remains unexplained.
75 Whatever steps Mr Akerman may have taken to obtain documents in other proceedings, the claimant had no explanation for why the swearing of his affidavit took four years. The claimant conceded that everything he swore in the affidavit of October 2002 he knew when he left the meeting in November 1998.
76 I consider that in all the circumstances the primary judge's exercise of discretion did not miscarry when he concluded that the delay has significantly prejudiced the opponent to the point where a fair trial would not be possible. It must be remembered that during this time, the Pasminco Group had gone into administration, the mine had been sold and employees dismissed and a new owner had taken over the mine.
77 I therefore consider that the primary judge gave adequate reasons for the exercise of his discretion and that there was no basis for challenging it as having miscarried in relation to the "just and reasonable" ground.
