BHP Billiton Ltd v Hamilton

In BHP Billiton Ltd v Hamilton, the Full Court of the Supreme Court of South Australia considered an appeal and cross-appeal concerning a finding of negligence and the assessment of damages for personal injury. The appellant, BHP Billiton Ltd, appealed against a finding of negligence and causation, while the respondent, Mrs Hamilton (representing the estate of Mr Hamilton), cross-appealed against the quantum of damages awarded for pain, suffering, and loss of amenities.

The primary legal issues before the court were whether the trial judge had erred in finding that BHP was negligent in its duty of care towards Mr Hamilton, whether BHP's negligence caused Mr Hamilton's contraction of mesothelioma, and whether the damages awarded for pain, suffering, and loss of amenities were manifestly inadequate. The court also considered the application and effect of a statutory presumption of causation in asbestos-related claims.

The Full Court, with Kourakis CJ agreeing, dismissed BHP's appeal, finding that the trial judge's conclusions regarding negligence were inevitable given the findings of knowledge of risk and the availability of precautionary measures. The court affirmed that a breach of duty is a cause of injury if it materially contributed to it, and that at common law, it must be proved on the balance of probabilities that the defendant's conduct caused or materially contributed to the injury. Regarding damages, the court held that it was permissible to have regard to comparable awards in other jurisdictions when assessing whether an award was manifestly inadequate or excessive. The court concluded that the initial assessment of $115,000 for pain, suffering, and loss of amenities was manifestly inadequate and re-assessed this amount at $190,000.
