Bennett v State of Tasmania

In Bennett v State of Tasmania, the dispute involved an application to correct an error in a decision made by the Administrative Appeals Tribunal (AAT). The Applicant sought to amend a judgment to rectify an error that was discovered post-decision, under what is known as the "slip" rule. The case was heard by the Federal Court of Australia, presided over by Justice Edelman.

The legal issues centred around the interpretation and application of the "slip" rule in administrative law, specifically whether the AAT had the implied power to correct errors in its decisions after the original order had been made. The Applicant argued that the error was apparent on the face of the record and that the correction should be made without the need for formal proceedings. The State of Tasmania opposed the application, contending that the AAT lacked the authority to alter its decisions post-hoc without following due process.

Justice Edelman found that the AAT does indeed possess the implied power to correct errors in its decisions under the "slip" rule. This power is necessary to ensure the integrity and fairness of administrative decisions. The Court emphasised that such corrections take effect from the date of the original order, thereby preserving the continuity and effect of the decision. Justice Edelman also clarified that notice of the corrected order is given when notice of the correction itself is provided, ensuring that all parties are appropriately informed of the amendment. This decision reinforces the principle that administrative bodies must strive for accuracy in their decisions, and that errors can be rectified when they are clear and apparent.
