St Vincent de Paul Society Aged and Special Services Limited (Lewisham Nursing Home) v Duinker

In the case of St Vincent de Paul Society Aged and Special Services Limited (Lewisham Nursing Home) v Duinker, the dispute involved the validity of an Arbitrator’s determination regarding the termination of an employee’s contract. The matter was heard in the Industrial Relations Commission of New South Wales. The central issue was whether the Arbitrator's determination was against the weight of evidence and whether he had considered all relevant medical evidence. Additionally, the court had to determine the onus of proof applicable in such circumstances.

The legal issues revolved around the standard of review applicable to an Arbitrator's decision, specifically whether the Arbitrator had erred in his assessment of the evidence. The claimant argued that the Arbitrator had overlooked critical medical evidence and had thereby made a determination that was against the weight of the evidence. The respondent maintained that the Arbitrator's decision was within his authority and correctly made. The court was required to examine the extent to which the Arbitrator had engaged with the evidence and whether the determination was justified.

The court found that the Arbitrator had indeed erred in his assessment by failing to adequately consider all the medical evidence. The court concluded that the determination was against the weight of the evidence, as the Arbitrator had not given sufficient weight to the claimant's medical evidence. Furthermore, the court clarified the onus of proof in such cases, stating that the party alleging the need for a particular consideration bears the onus of proving it. The court revoked the Arbitrator's decision and substituted its own, providing specific reasons for the change.

The court’s final order revoked the decision of the Arbitrator dated 20 November 2006 and made a new decision in its place, reflecting the findings that the Arbitrator had failed to properly consider all the evidence and had made a determination against the weight of the evidence. The new decision detailed the proper considerations and conclusions that should have been reached by the Arbitrator.
