Davies v Adelaide Chemical and Fertilizer Co Ltd

The plaintiff, William David Davies, appealed to the High Court of Australia against a decision of the Supreme Court of South Australia. Davies, employed as a greaser by Adelaide Chemical and Fertilizer Co. Ltd., sustained an injury when his arm was caught between a moving conveyor belt and a roller while he was lubricating the machinery. He claimed damages, alleging a breach of the defendant's statutory duty under section 321 of the Industrial Code 1920-1943 (S.A.) to safeguard dangerous machinery. The trial judge found that the defendant had breached this duty, but dismissed the plaintiff's claim on the grounds of contributory negligence.

The central legal issue before the High Court was whether the plaintiff's actions constituted contributory negligence, thereby disentitling him from recovering damages for the defendant's breach of statutory duty. Specifically, the court had to determine if the plaintiff's practice of greasing the machinery while the belt was in motion, despite knowing of the risk and the possibility of having the machine stopped, amounted to negligence that was the effective cause of his injury.

A majority of the High Court (Latham C.J., Dixon, and McTiernan JJ.) held that the evidence did not support the finding of contributory negligence. They reasoned that the plaintiff's conduct, while involving a known risk, was consistent with momentary inattention or thoughtlessness rather than a deliberate, foolhardy disregard of a realised danger. The court emphasised that the statutory duty to safeguard machinery was designed to protect workers from precisely the kind of risks associated with operating machinery in motion, and that the plaintiff's actions, which were a long-standing practice known to management and not expressly forbidden, did not amount to such culpability as to relieve the employer of its statutory responsibility. The appeal was allowed, and the case was remitted for the assessment of damages. Rich and Starke JJ. dissented, finding that the plaintiff's deliberate choice to take a known risk, despite the availability of safer alternatives, constituted contributory negligence that barred his claim.
