National Australia Bank Limited v The Minister for the Time Being Administering the Sea Fisheries Act 1963 (Tasmania)

This matter came before the High Court of Australia as an application for special leave to appeal. The applicant was National Australia Bank Limited, and the respondent was the Minister for the Time Being Administering the Sea Fisheries Act 1963 (Tasmania). The core of the dispute concerned the adequacy of reasons provided by a decision-maker for a statutory decision.

The legal issues before the Court involved determining whether a decision-maker, who is statutorily obliged to provide reasons for a decision, is taken to have considered a substantial matter raised before them if that matter is not explicitly mentioned in the stated reasons. It also raised a conflict between lines of authority: one line suggesting that the stated reasons are the sole basis for assessing whether all relevant matters were considered, and another line holding that a failure to properly comply with a statutory direction to give reasons constitutes an error of law in itself.

The applicant submitted that a failure to refer to a substantial matter in the reasons for a decision, when a statute requires reasons to be given, means the decision-maker has not properly complied with their statutory obligations. The applicant argued that the Full Court of Tasmania had contravened this principle. The Chief Justice of the High Court noted that the issue of whether a decision-maker must advert to all substantial matters in their reasons had been dealt with by Mr Justice Cox in the Full Court and rejected by him, but it had not been specifically addressed in explicit terms by the Chief Justice of the Full Court or the other judge who agreed with him. Justice Brennan observed that the judgments in the Full Court did not appear to consider this specific point.
