Factual and Procedural Background
This case concerns a claim by the Plaintiff, now the Appellant, for provisional damages arising from the development of pleural plaques due to asbestos exposure. The writ of summons was issued on 13 March 2015, with the statement of claim dated 29 June 2016, and the notice of set down dated 30 November 2018. The Plaintiff, born in March 1951, developed pleural plaques as a secondary victim from domestic exposure to asbestos dust and fibres brought home by his father, who worked as a pipe lagger at Company A’s shipyard from 1948 to 1983. The father was employed either directly by Company A or by specialist pipe lagging contractors such as Company B (the second Defendant). Two other defendants initially named in the proceedings were later removed from the case.
The appeal arises from a decision by the trial judge dated 21 December 2022, which dismissed the Plaintiff’s claim and awarded costs to the first and second Defendants. The appeal advances two grounds: (i) that the judge erred in law by concluding the Plaintiff did not prove on a balance of probabilities that his asbestos exposure between November 1965 and 1974 materially increased his risk of developing pleural plaques, and (ii) that the judge erred in awarding costs against the Plaintiff without allowing him an opportunity to make submissions on that issue.
Legal Issues Presented
- Whether the Plaintiff proved on the balance of probabilities that exposure to asbestos between November 1965 and 1974 materially increased his risk of developing bilateral calcified pleural plaques.
- Whether the judge erred in awarding costs against the Plaintiff without affording an opportunity to make submissions.

Court's Reasoning and Analysis
The court began with the trial judge’s foundational findings that the Plaintiff developed pleural plaques caused by asbestos exposure from his father’s contaminated work clothing in the domestic environment. The law was agreed by all parties, applying the Holtby principles for divisible asbestos injuries, requiring proof that a defendant materially increased the risk of injury over a time-based period post-November 1965.
The judge had dismissed the Plaintiff’s claim on the basis that the medical evidence did not prove that exposure between 1965 and 1974 materially contributed to the risk of pleural plaques. The court found this dismissal erroneous, highlighting that the medical evidence was admitted without objection and was consistent with credible witness testimony about ongoing exposure in the family home until the Plaintiff’s marriage in 1974.
The court noted the significant concessions by the Defendants acknowledging secondary exposure through contaminated clothing up to the mid-1970s. It also observed that the trial judge’s comments suggested a possible misunderstanding, conflating issues of liability and quantum (apportionment). The court found that the judge was plainly wrong to reject the medical evidence and the overall case without sufficient explanation.
Considering the totality of evidence, including the Plaintiff’s testimony, family members’ evidence, and the conceded facts, the court concluded that exposure during the relevant period materially contributed to the risk of developing pleural plaques. The court emphasized the difficulty in precisely quantifying exposure or timing but endorsed the time-based approach agreed by the parties.
Finally, the court approved that any reduction in the apportionment fraction based on intensity of exposure (for example, reduced exposure during teenage years) should be addressed rather than dismissing the claim outright.
Holding and Implications
The appeal is allowed on the first ground.
The court reversed the trial judge’s dismissal of the Plaintiff’s claim, holding that the Plaintiff did prove that asbestos exposure between November 1965 and 1974 materially increased his risk of developing pleural plaques. The case is remitted for the parties to discuss apportionment and the applicable fraction of liability. The court did not find it necessary to decide the second ground of appeal regarding costs at this stage but indicated that submissions on costs may follow.
The decision directly affects the parties by reinstating the Plaintiff’s claim for provisional damages and requiring further consideration of apportionment. No new legal precedent was established, as the court applied existing principles agreed by the parties.
