Harris v Commercial Minerals Ltd

The High Court of Australia considered the appeal in *Harris v Commercial Minerals Ltd*. The case concerned a claim for damages for personal injury arising from the plaintiff's exposure to silica dust during his employment with the defendant. The plaintiff alleged that the defendant had breached its duty of care by failing to provide a safe working environment, leading to the development of silicosis.

The central legal issue before the High Court was whether the plaintiff's claim was barred by the operation of s 139 of the *Workers Compensation Act 1987* (NSW) (the Act). Section 139 of the Act provides that a worker who has received or is entitled to receive weekly payments under the Act is not entitled to bring proceedings for damages against their employer for an injury sustained in the course of employment. The court was required to determine the scope and effect of this statutory bar, particularly in circumstances where the worker had not yet commenced receiving weekly payments but was entitled to do so.

The High Court held that the plain wording of s 139(1) of the Act indicated that the entitlement to receive weekly payments, rather than the actual receipt of such payments, was the trigger for the statutory bar. The majority reasoned that the purpose of the provision was to provide a statutory scheme of compensation and to prevent double recovery. Therefore, the plaintiff's entitlement to weekly payments under the Act meant that he was precluded from pursuing a common law claim for damages against his employer. The court affirmed the decision of the New South Wales Court of Appeal.
