Williams v Fraser

The case of *Williams v Fraser* concerned an appeal from a judgment in favour of the respondent, Ms Fraser, who had sued the appellant, Dr Williams, for negligence. Ms Fraser alleged that Dr Williams, a medical practitioner, had failed to diagnose her condition, and that this failure had caused her harm. The appeal was heard by Macfarlan and Gleeson JJA and Simpson AJA.

The central legal issue before the appellate court was whether Dr Williams' failure to diagnose Ms Fraser's condition had caused her harm. This involved an examination of the causal link between the alleged negligence and the resulting injury, specifically considering the concept of "loss of chance" in the context of medical negligence. The court also considered the function of an appellate court when reviewing findings of fact that were based solely on an analysis of complex medical evidence.

The court's reasoning focused on the evidence presented at trial regarding the diagnosis and treatment of Ms Fraser's condition. It was held that the primary judge's findings of fact, which were derived from a detailed analysis of the medical evidence, were not demonstrably wrong. The appellate court affirmed that where a finding of fact is purely based on the analysis of expert evidence, an appellate court should be slow to interfere with that finding unless it is clearly erroneous. Consequently, the appeal was dismissed, and the appellant was ordered to pay the respondent's costs.
