Papadopoulos v New South Wales Insurance Ministerial Corporation

The New South Wales Court of Appeal considered a claim for personal injury arising from a motor vehicle accident. The appellant, Mr. Papadopoulos, alleged that the accident caused a perfusion failure to the foetus he was carrying, resulting in cerebral palsy. The respondent was the Nominal Defendant, representing the insurer of the unidentified driver involved in the accident.

The central legal issues before the Court of Appeal were whether the trial judge had erred in his assessment of the expert evidence concerning causation, and whether the trial judge had applied the correct legal test for causation in the circumstances. Specifically, the Court examined whether the trial judge had been unduly distracted by intermediate factual issues and had failed to consider all material circumstances when determining whether the accident caused the foetal injury.

The Court of Appeal found that the trial judge had misapplied the principles of causation. It held that while expert evidence is crucial in cases involving complex medical issues, the ultimate determination of causation rests with the court, applying a commonsense approach. The Court emphasised that causation in such cases is not always susceptible of scientific demonstration or proof, and the legal test of the balance of probabilities must be applied. The Court also noted that the demeanour of expert witnesses is a relevant consideration when experts are in conflict, but it should not overshadow the substance of their evidence.

The appeal was allowed.
