Australian Telecommunications Commission v Barker

The Australian Telecommunications Commission sought to appeal a decision of the Administrative Appeals Tribunal (AAT), which had affirmed a determination that the respondent, Barker, was not liable to pay compensation to the appellant. The dispute involved the interpretation of the Compensation (Commonwealth Government Employees) Act 1971 (Cth) and the adequacy of the reasons provided by the AAT for its decision. The trial judge had found that the appellant was entitled to compensation, leading to a conflict with the AAT's decision.

The court was required to determine whether the AAT had failed to state reasons for its decision and whether there was an error of law. Additionally, the court needed to assess whether the trial judge's finding that the appellant was entitled to compensation was open on the evidence before the AAT. The issues of causation and the onus of proof in administrative proceedings were also discussed.

The court found that the AAT had indeed failed to state reasons for its decision, leading to an error of law. The tribunal's reasoning did not adequately address the evidence or the applicable legal principles. The trial judge's finding that the appellant was entitled to compensation was open on the evidence before the AAT. Consequently, the appeal was allowed, and paragraphs 3, 4 and 5 of the orders made by the trial judge were set aside. The matter was remitted to the AAT to be heard and decided again with or without the hearing of further evidence.
