Pasminco Mining Broken Hill v Manera

Pasminco Mining Broken Hill Pty Ltd (the appellant) appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales. The dispute concerned the appellant's liability for dust diseases contracted by former employees, including the respondent, Mr. Manera, who had worked at the Broken Hill mine. The primary claim was for damages for negligence and breach of statutory duty.

The Court of Appeal was required to determine whether the appellant owed a duty of care to its employees regarding the risk of contracting dust diseases, and if so, whether that duty had been breached. Further issues included the appellant's knowledge of the risks associated with dust exposure in the mine and the adequacy of the precautions taken to mitigate those risks. The court also considered the application of the relevant legislation concerning mining safety and the standard of care expected of a mining operator in the circumstances.

The Court of Appeal found that the appellant had a duty of care to its employees to take reasonable steps to prevent them from contracting dust diseases. This duty extended to warning employees of the risks and implementing appropriate control measures. The court held that the appellant had breached this duty by failing to adequately warn employees of the dangers of dust inhalation and by not implementing sufficient measures to control dust levels in the mine. The court applied principles of negligence, considering the foreseeability of harm and the reasonableness of the precautions that ought to have been taken, taking into account the knowledge available at the time regarding the link between dust exposure and lung diseases.

The appeal was dismissed, and the Supreme Court's decision in favour of the respondent was upheld.
