Murray v Commissioner of Police

The appeal concerned a dispute between Mr Murray and the Commissioner of Police regarding a claim for workers' compensation for an injury sustained on duty. The matter came before the Court of Appeal of New South Wales, with Giles, Ipp and Tobias JJA presiding.

The central legal issues before the Court of Appeal were whether the primary judge had made an error of law in finding that the appellant's injury was caused during the course of his employment, and whether the evidence before the primary judge supported this finding. Additionally, the court considered the doctrine of issue estoppel, specifically whether the Commissioner of Police was a privy of the SAS Trustee Corporation, and if a prior decision of the Industrial Relations Commission (IRC) had any preclusive effect on the present proceedings.

The Court of Appeal found that there was no evidence to support the primary judge's finding on the cause of the injury. The court determined that the Commissioner of Police and the SAS Trustee Corporation did not share a common interest, and therefore the Commissioner was not a privy of the SAS Trustee Corporation for the purposes of issue estoppel. Consequently, the court allowed the appeal, set aside the orders of the primary judge, and remitted the matter to the District Court for further determination. The court stipulated that the evidence at the further determination should be limited to that before the primary judge, unless leave was granted to adduce further evidence. The costs of the proceedings before the primary judge were to abide the further determination, while the respondent was ordered to pay the appellant's costs of the appeal.
