Commissioner of Police v David Rea

The Commissioner of Police appealed to the Court of Appeal of New South Wales against a decision of the Workers Compensation Commission which had found that the respondent, David Rea, had suffered a compensable injury. The dispute concerned whether Mr Rea's employment as a police officer had caused his injury, notwithstanding certain medical evidence presented.

The primary legal issue before the Court of Appeal was whether the Workers Compensation Commission had erred in finding a causal link between Mr Rea's employment and his injury, particularly in light of the medical evidence which suggested the injury was not work-related. The court was required to determine if it was open to the Commission, as a lay tribunal, to find causation despite the medical opinions.

The Court of Appeal held that the Commission was entitled to reach its own conclusion on causation, even if it differed from the medical experts. The court reasoned that medical evidence, while important, is not determinative of causation in workers' compensation matters. Lay tribunals are permitted to weigh all the evidence, including lay testimony and their own understanding of causation, and can find a causal connection where medical opinion does not support it, provided there is sufficient evidence to justify that finding. The appeal was dismissed with costs.
