Canute v Comcare

The High Court of Australia considered an appeal by Mr. Canute against a decision of the Full Federal Court, which had affirmed a decision of the Administrative Appeals Tribunal. The dispute concerned Mr. Canute's claim for compensation under the *Safety, Rehabilitation and Compensation Act 1988* (Cth) (the Act) for a psychiatric injury allegedly sustained during his employment with the Australian Federal Police. Comcare had denied liability for the claim.

The central legal issue before the High Court was whether Mr. Canute's psychiatric condition constituted an "injury" as defined by section 5B(1) of the Act. Specifically, the Court had to determine whether the injury was suffered "in the course of his employment" and whether it was caused by the employer's failure to take reasonable care for the safety of the employee, or by certain other specified circumstances, including the reasonable administration of the employer's personnel policies.

The High Court, in a majority decision, held that the Tribunal and the Full Federal Court had erred in their interpretation of section 5B(1)(b) of the Act. The majority found that the Tribunal had incorrectly applied the test for causation, focusing on whether the employer's actions were the sole or dominant cause of the injury, rather than whether they were a contributing cause. The Court clarified that the employer's conduct need only be a contributing cause to the injury, not necessarily the sole or dominant one. The appeal was allowed, and the matter was remitted to the Administrative Appeals Tribunal for redetermination according to law.
