Adelaide Stevedoring Co Ltd v Forst

The case of *Adelaide Stevedoring Co Ltd v Forst* involved an appeal to the High Court of Australia concerning a claim for workers' compensation. The respondent, Mrs. Forst, sought compensation following the death of her husband, a waterside worker and winchman, who collapsed and died shortly after performing tasks involving significant physical exertion. The appellant, Adelaide Stevedoring Co Ltd, contested the claim.

The central legal issue before the High Court was whether the workman's death from coronary thrombosis was an injury by accident arising out of and in the course of his employment, as defined by the *Workmen's Compensation Act 1932-1935* (S.A.). This required determining if the physical exertion undertaken by the deceased had a causal connection to his death.

The High Court, by a majority, affirmed the decision of the Supreme Court of South Australia. The court considered conflicting medical evidence regarding the relationship between physical exertion and coronary thrombosis. While the arbitrator had found that death from coronary thrombosis could not generally be related to exertion, the Supreme Court had concluded, based on the probabilities and the expert testimony, that the workman's exertion was the inciting cause of his coronary thrombosis. The High Court found this conclusion to be justified by the evidence, holding that the exertion was a material contributing factor to the death, thus satisfying the requirements of the Act.
