Commonwealth of Australia v De Castro

The Commonwealth of Australia appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales, which had found the Commonwealth liable in negligence for injuries sustained by Mr. De Castro. Mr. De Castro, a former member of the Royal Australian Air Force (RAAF), alleged that his injuries were caused by the negligent failure of the Commonwealth to provide him with adequate protection from exposure to asbestos during his service.

The central legal issue before the Court of Appeal was whether the Commonwealth owed a duty of care to Mr. De Castro in relation to the provision of a safe working environment, and if so, whether that duty had been breached. Specifically, the court had to consider the scope of the employer's duty of care in the context of military service and whether the Commonwealth had acted reasonably in its assessment and management of the risks associated with asbestos exposure during the period of Mr. De Castro's service.

The Court of Appeal, in its reasoning, affirmed the general principles of employer's liability in negligence. It held that the Commonwealth, as an employer, owed a duty of care to its service personnel to take reasonable steps to prevent foreseeable harm. The court examined the knowledge available to the Commonwealth regarding the dangers of asbestos at the relevant times and assessed whether the precautions taken were sufficient to meet the standard of reasonable care. The court found that the Commonwealth had failed to take reasonable steps to protect Mr. De Castro from the foreseeable risks of asbestos exposure, thereby breaching its duty of care.

Consequently, the Court of Appeal dismissed the Commonwealth's appeal and upheld the Supreme Court's finding of liability. The court affirmed the damages awarded to Mr. De Castro, finding them to be appropriate in the circumstances.
