ACN 005 057 349 Pty Ltd v Commissioner of State Revenue

ACN 005 057 349 Pty Ltd sought judicial review of decisions made by the Commissioner of State Revenue, who raised a land tax liability twice with respect to the same landholding. The taxpayer had made payments in the mistaken belief that the assessments accurately identified their landholdings. The taxpayer sought a refund of overpayments and mandamus to compel the Commissioner to amend the assessments. The court had to determine whether the Commissioner could amend the assessments, if the recovery of overpayments was precluded by limitation periods, and if compound interest was recoverable. The Commissioner admitted to a duplication error for 2008-2011 but refused to refund excess payments for 1990-2002. The court held that the Commissioner had a discretionary power to amend assessments to ensure completeness and accuracy, and the refusal to exercise this power amounted to conscious maladministration. Therefore, the court issued a mandamus to compel the amendments. The court also found that the recovery of overpayments was not precluded by limitation periods, as the mistake could have been discovered with reasonable diligence. The court held that compound interest was not recoverable, as there were no exceptional circumstances or conscious maladministration. The court dismissed the taxpayer’s claim for restitution, as the requirement for a claim for restitution was necessary to establish liability. The court referred to the decisions in Commissioner of State Revenue (Vic) v Royal Insurance Australia Ltd, Finance Facilities Pty Ltd v Federal Commissioner of Taxation, and Federal Commissioner of Taxation v Futuris Corporation Ltd. The court also referred to the Land Tax Act 1958, the Limitation of Actions Act 1958, and the Supreme Court Act 1986. The court dismissed the taxpayer’s claim for compound interest but granted the claim for mandamus to compel the Commissioner to amend the assessments.
