Tudor Capital Australia Pty Limited v Christensen

This matter concerned an appeal to the Court of Appeal of New South Wales from a decision of the Deputy President of the Workers Compensation Commission. The appellant, Tudor Capital Australia Pty Limited, sought to overturn the Deputy President's finding that the respondent's late husband, Mr Christensen, had suffered an "injury" within the meaning of the *Workers Compensation Act 1987* (NSW). Mr Christensen had died from ventricular fibrillation causing cardiac arrest, and the dispute centred on whether his employment had been a substantial contributing factor to this event, and whether the Deputy President had correctly identified an "injury" under the Act.

The primary legal issues before the Court of Appeal were whether the Deputy President erred in law by identifying the "experience of stress" as an "injury" under section 4 of the *Workers Compensation Act 1987* (NSW), and whether this constituted a "psychological injury" for the purposes of section 11A of the Act. Further, the court considered whether the Deputy President's finding of injury was supported by sufficient evidence, particularly in light of competing medical evidence regarding the cause of death, and whether the Deputy President's reasoning processes were adequate. The court also addressed whether the appellant had raised a new issue on appeal without affording the respondent procedural fairness.

The Court of Appeal held that the Deputy President had erred in law by identifying the "experience of stress" as an "injury" under section 4 of the *Workers Compensation Act 1987* (NSW). The court clarified that stress, in itself, is not an injury, but rather a factor that can contribute to an injury. The Deputy President's finding that the employment was a substantial contributing factor to Mr Christensen's death was set aside due to this error. The court found that the Deputy President's reasoning processes were inadequate in analysing the medical evidence and that there was insufficient proof to support a finding of probable causal connection between the employment and the death.

Consequently, the appeal was allowed, and the decision of the Deputy President was set aside. The matter was remitted to the Workers Compensation Commission for redetermination according to law.
