Original judgment source is linked above.
(This judgment was delivered extemporaneously on 30 July 2025 and has been edited to include complete references and so as to correct infelicities of language.)
(a) he most recently spoke with the plaintiff on 11 December 2024, at which time the plaintiff stated that he was 'all good' with no respiratory concerns or complaints, and that the plaintiff had had no further silica exposure since his diagnosis;
(b) he had reviewed the plaintiff's CT scans from 2020, 2022 and December 2024 and opined that his review of them and findings were consistent with simple silicosis;
(c) based on the information available to him, his opinion is that the plaintiff has silicosis, and given the time since first exposure and the radiological appearance, it would be classified as chronic simple silicosis;
(d) based on the lack of reported symptoms, normal lung function and cardiopulmonary function tests, the plaintiff's impairment (using the AMA Guides to Permanent Impairment due to respiratory disorders, table 5 ‑ 12) is estimated to be class 1 ‑ 0 (zero)%;
(e) in his opinion, the plaintiff's history of exposure to respirable silica dust while working in the stonemasonry industry in Western Australia caused, and/or materially contributed to the development of his lung disease; and
(f) he had been asked to provide his opinion as to the plaintiff's likely prognosis because of lung disease and to comment on the likelihood of it progressing in the future, in response to which he noted as follows:
The natural history of silicosis is very variable. [The plaintiff] has stopped smoking and ceased further silica exposure around 4-5 years ago, which is critical.
To date, there has been no radiological or physiological progression of disease and [the plaintiff] remains asymptomatic. Given that there is no further exposure to silica occurring, it is plausible that there may be no progression of disease or impairment in the future.
However, even after cessation of exposure, simple silicosis can still progress, but the rate of progression is generally lower than if exposure has continued. Contemporary data following artificial stone exposure are sparse, however, there is no reason to believe that the nature of the silicosis is different from artificial stone exposure compared to other forms of silica exposure.
Factors that may influence progression include severity of disease at time of diagnosis, total (cumulative) exposure history, individual factors such as age, tobacco smoke exposure, and genetics.
Symptoms and disease progression may progress over years, but removing further silica exposure is the main intervention shown to slow or arrest rapid progression. (footnotes omitted)
(a) general damages for future pain and suffering (non‑economic loss);
(b) damages for future out-of-pocket expenses, including medical, hospital, and pharmaceutical expenses, as well as the cost of future commercial care and domestic assistance;
(c) damages for future need for gratuitous care and domestic assistance from members of his household (described by Mr McGinley as 'Griffiths v Kerkemeyer [1977] HCA 45 type damages'); and
(d) damages for future loss of earning capacity, if his disease were to progress to a stage where it prevented him from working.
The Plaintiff therefore seeks to allow as much time as possible to pass, since his initial diagnosis of silicosis, to determine whether there is any evidence of progression of his disease, which could significantly impact his claim for damages.
I certify that the preceding paragraph(s) comprise the reasons for decision of the Supreme Court of Western Australia.
