Citation: Zaya v Damirdjian [2022] NSWCA 203
Jurisdiction: Court of Appeal, Supreme Court of NSW
Before: Bell CJ, Gleeson JA and Griffiths AJA
The Plaintiff was riding his motorcycle when he lost control due to another vehicle pulling out in front of him, without warning, to make a U-turn. The Plaintiff commenced proceedings against the Nominal Defendant and a person believed to have been the driver of the other vehicle.
Both Defendants alleged, amongst other things, that the Plaintiff had contributed to his injuries by speeding prior to the accident. This followed a police prosecution for negligent driving where the Local Court rejected the Plaintiff’s denial that he was speeding.
The Primary Judge delivered a verdict in favour of the Plaintiff. In relation to contributory negligence, the lower Court rejected the evidence of the investigating police officer because of errors in his estimate of the Plaintiff’s speed and length of skid/gauge marks. The Primary judge preferred the Plaintiff’s evidence regarding speed as it was consistent with contemporaneous reports made to treatment providers, witness testimony and evidence from the Plaintiff’s own expert. The opinion from the Defendant’s expert was rejected due to its unduly speculative foundations concerning the police and other evidence.
On appeal, both Defendants alleged the Primary Judge erred in failing to find the Plaintiff was travelling at an excessive speed prior to the accident. They contended that there should be a finding of at least 50% contributory negligence on this basis.
The Court unanimously dismissed the appeal relating to contributory negligence. There was no error in the Primary Judge’s conclusions on the following basis:
Regarding the last-mentioned point, the court observed that it was unlikely the contemporaneous hospital record in which the Plaintiff stated he had been travelling well below the speed limit, was the consequence of a calculated artificial self-serving reconstruction.
The court upheld the primary judge’s finding that until the other vehicle commenced the U-turn without indication, the Plaintiff was without notice of particular hazards requiring a lesser speed. His evidence on that issue was, on its face credible, and not inherently improbable. Given that the Defendant’s expert accepted the correctness of the police evidence about skid and gouge marks-and this transpired to be wrong-his opinion was flawed.
The grounds of appeal relating to contributory negligence were dismissed. The Appeal was, however, allowed on other grounds.
This case highlights the limitations of expert evidence in cases where factual matters are in dispute. Expert opinion will carry little weight if the accuracy of the underpinning factual basis is flawed.
The decision also reminds us of the important role played by contemporaneous evidence in resolving factual disputes.
Finally, the case also underscores the burden of proof that insurers carry in establishing a defence of contributory negligence. Findings made in answer to a police prosecution don’t always translate in a damages claim.
