Marelic v Comcare

In the Federal Court of Australia, Marelic, the applicant, brought an appeal against the decision of the Administrative Appeals Tribunal (the Tribunal), which had dismissed her claim for compensation. The Tribunal found that the applicant had not discharged the onus of proving that her psychiatric injury was caused by a work-related event. The applicant contended that the Tribunal had breached the rules of natural justice by failing to put certain matters to her during cross-examination that related to her credit. Specifically, the Tribunal did not inquire about the applicant's previous psychiatric history, which was relevant to her current claim. The applicant argued that this constituted a failure to observe procedural fairness and that the Tribunal's decision should be overturned.

The court was required to determine whether the Tribunal had breached the rules of procedural fairness by not putting certain matters to the applicant during cross-examination. Additionally, the court had to assess whether the error affected the outcome of the decision and whether the breach was remedied by the opportunity to recall the applicant. The court had to consider the application of the rule in Browne v Dunn in the context of Tribunal proceedings and whether the Tribunal was entitled to rely on its observations of the witness.

The court found that the Tribunal had indeed breached the rules of procedural fairness by not putting matters concerning the applicant's credit to her during cross-examination. The court held that the Tribunal's failure to do so was a substantial procedural error, as it deprived the applicant of the opportunity to respond to relevant matters that could have impacted the outcome of the decision. The court also held that the error was not remedied by the opportunity to recall the applicant, as the Tribunal had already formed its view on the applicant's credit based on its observations of her during the hearing. The court concluded that the error affected the outcome of the decision, and therefore, the Tribunal's decision should be set aside and the matter remitted for redetermination.

The court ordered that the decision of the Tribunal be set aside, the matter be remitted to the Tribunal for redetermination according to law with or without further evidence, and that the respondent pay the applicant's costs. The court emphasised the importance of procedural fairness in administrative law and the need for tribunals to ensure that all relevant matters are put to witnesses during cross-examination. The court also highlighted the need for tribunals to be cautious when relying on their observations of witnesses, as it may not be sufficient to establish the credibility of a witness.
