Mann v Commonwealth of Australia

The High Court of Australia heard an appeal in *Mann v Commonwealth of Australia*. The dispute concerned the validity of a notice issued by the Australian Taxation Office (ATO) to the Commonwealth Bank of Australia, requiring the bank to pay to the Commissioner of Taxation amounts that the bank owed to Mr Mann, a taxpayer. The ATO sought to recover outstanding tax debts owed by Mr Mann.

The central legal issue before the High Court was whether the notice issued by the Commissioner under s 218 of the *Income Tax Assessment Act 1936* (Cth) was valid and effective to compel the Commonwealth Bank to pay to the Commissioner amounts it owed to Mr Mann, thereby satisfying Mr Mann's tax liability. This involved an interpretation of the scope and operation of s 218, particularly in relation to the nature of the debt owed by the bank to the taxpayer.

McHugh and Callinan JJ, in separate judgments, both found that the appeal should be dismissed. Their Honours held that s 218 of the *Income Tax Assessment Act 1936* (Cth) was a valid and constitutional provision that empowered the Commissioner to issue a notice to a third party who owed money to a taxpayer. The court reasoned that the section was designed to facilitate the recovery of tax debts and that the debt owed by the Commonwealth Bank to Mr Mann was a debt to which s 218 applied. The notice was therefore effective in requiring the bank to pay the Commissioner the amounts it owed to Mr Mann, up to the extent of his tax liability.
