Allianz Australia Ltd v Sim

The appeal concerned three matters heard together, brought by Allianz Australia Ltd against Mrs Sim. The dispute centred on whether the Dust Diseases Tribunal Regulation 2007 (NSW) was inconsistent with the Uniform Civil Procedure Rules 2005 (NSW) regarding offers of compromise, and the admissibility and weight of expert evidence concerning the causal link between asbestos exposure and lung cancer. The case was heard in the Court of Appeal of New South Wales.

The primary legal issues before the Court of Appeal were: (1) whether the Dust Diseases Tribunal Regulation 2007 (NSW), specifically Part 6, operated only to the extent that it was not inconsistent with the Uniform Civil Procedure Rules 2005 (NSW); (2) whether Allianz had provided all necessary documents to enable Mrs Sim to consider an offer of compromise under the Uniform Civil Procedure Rules; (3) whether the offer of compromise was open for a reasonable time; (4) whether it was appropriate to consider all evidence to determine the admissibility of expert evidence; and (5) whether a pathologist was able to give evidence as to the causal connection between asbestos dust exposure and lung cancer, given the current state of medical knowledge, and whether an increase in risk could be equated with factual causation.

The Court of Appeal held that the Dust Diseases Tribunal Regulation 2007 (NSW) did not operate to the exclusion of the Uniform Civil Procedure Rules 2005 (NSW) where inconsistency arose. It found that the offer of compromise was not open for a reasonable time and that the appellant had not provided all necessary documents. Regarding the expert evidence, the Court determined that it was appropriate to consider all evidence to assess admissibility and that the pathologist's opinion on the causal link between asbestos exposure and lung cancer was admissible and could be accepted by the Tribunal, as an increase in risk could be equated with factual causation in this context.

In each of the three matters, the appeal was dismissed, and the appellant, Allianz Australia Ltd, was ordered to pay Mrs Sim's costs.
