Eyles v Government Insurance Office of New South Wales

The New South Wales Court of Appeal considered an appeal by the plaintiff, Eyles, against the Government Insurance Office of New South Wales (GIO). The dispute concerned the plaintiff's entitlement to a statutory benefit under the *Workers Compensation Act 1987* (NSW) for a psychiatric injury allegedly sustained in the course of his employment. The primary judge had found that the plaintiff had not established that his psychiatric condition was caused by his employment.

The central legal issue before the Court of Appeal was whether the primary judge had erred in finding that the plaintiff had failed to prove that his psychiatric injury was a consequence of his employment. This involved a determination of whether the plaintiff's subjective experience of workplace events, and the resulting psychological impact, met the threshold for a compensable injury under the relevant legislation, particularly in light of the employer's knowledge or constructive knowledge of the circumstances giving rise to the injury.

The Court of Appeal analysed the evidence presented at trial, including medical and lay testimony, to assess whether the primary judge's findings of fact were against the weight of that evidence. The Court applied the principles of causation in workers' compensation law, which require a causal link between the employment and the injury. It considered whether the plaintiff's psychiatric condition was a result of his employment, or whether it arose from other factors, and whether the employer had sufficient notice of the circumstances that might lead to such an injury. The Court ultimately found that the primary judge's conclusion was not demonstrably wrong and that the plaintiff had not discharged the onus of proof.

The appeal was dismissed, with the Court of Appeal affirming the decision of the primary judge.
