Lederer Group Pty Ltd v Hodson

The Lederer Group Pty Ltd appealed to the Court of Appeal of New South Wales against a judgment that found it liable for negligence causing psychiatric injury to its employee, Mr. Hodson. Mr. Hodson had alleged that his exposure to a traumatic incident during the course of his employment led to him developing post-traumatic stress disorder and major depressive disorder. The central dispute concerned whether Mr. Hodson was actually exposed to the incident, whether such exposure caused his diagnosed conditions, and whether the Lederer Group breached its duty of care to him.

The Court of Appeal was required to determine several key legal issues. Firstly, it had to assess whether Mr. Hodson had proven, on the balance of probabilities, that he was exposed to the traumatic incident in a manner that could cause psychiatric harm. Secondly, the Court needed to consider whether the Lederer Group breached its duty of care to Mr. Hodson by failing to direct him not to attend the incident, or by failing to take other reasonable steps to prevent harm. Thirdly, the Court had to determine whether the provisions of section 32 of the *Civil Liability Act 2002* (NSW), which impose specific requirements for establishing liability for psychiatric injury, were satisfied. Finally, the Court had to evaluate the weight and reliability of the expert evidence presented by Mr. Hodson regarding causation.

The Court of Appeal found that the expert evidence relied upon by Mr. Hodson was of little to no weight in establishing causation. This was because the assumptions upon which the experts based their opinions were not proven on the facts, and the facts as proved were dissimilar from those assumptions. Consequently, the Court concluded that Mr. Hodson had failed to establish that his exposure to the incident, as it actually occurred, caused his psychiatric conditions. Furthermore, the Court found that the Lederer Group had not breached its duty of care.

Accordingly, the appeal and cross-appeal were each allowed with costs.
