J v D

The appeal concerned a motor accident claim where the appellant suffered an atypical psychotic disorder. The central dispute revolved around whether the primary judge erred in finding that the motor accident accelerated the development of the appellant's psychotic disorder by four years, from an anticipated onset in 2020 to 2016. The appeal was heard by Leeming, White, and Brereton JJA.

The legal issues before the Court of Appeal were whether the primary judge made an error in their factual finding regarding the acceleration of the appellant's psychotic disorder due to the accident, and specifically, whether the finding that this acceleration occurred by four years was erroneous. This required a close examination of the evidence and the primary judge's reasoning concerning the appellant's pre-existing susceptibility to such a disorder.

The Court of Appeal dismissed the appeal, finding no error in the primary judge's determination. The reasoning focused on the evidence presented at trial, which supported the conclusion that the accident had indeed accelerated the onset of the psychotic disorder. The legal principle applied was that an appellant must demonstrate a material error of fact or law to overturn a primary judge's findings, and in this instance, the evidence was sufficient to uphold the original finding of acceleration. The appeal was dismissed with costs.
