Welch Perrin & Co Pty Ltd v Worrel

Welch Perrin & Co Pty Ltd (the appellant) appealed to the High Court of Australia from a judgment of the Supreme Court of Victoria. The dispute concerned the appellant's liability for injuries sustained by the respondent, Mr. Worrel, who was employed by the appellant as a salesman. Mr. Worrel alleged that he had contracted a disease, described as a "tropical disease," as a result of his employment, and that the appellant had breached its duty of care to him.

The High Court was required to determine whether the appellant had breached its duty of care to the respondent by failing to take reasonable precautions to prevent him from contracting the disease. Specifically, the court had to consider whether the appellant knew or ought to have known of the risk of contracting such a disease from the conditions of employment and whether it failed to implement adequate measures to mitigate that risk.

The court found that the appellant had not breached its duty of care. It reasoned that the evidence did not establish that the appellant knew or ought to have known that the respondent was exposed to a risk of contracting the disease in question as a result of his employment. The appellant's duty of care extended only to risks that were reasonably foreseeable. In the absence of such foreseeability, the appellant could not be held liable for failing to take precautions against a risk that was unknown to it. The appeal was therefore allowed.
