The Court held, contrary to the views of Shaw J in Deputy Commissioner of Taxation v De-Angelis (2008) SADC 103 that s 8AAZN(2) cannot be overridden by the general GIC provisions contained in the RBA provisions, that the legislation entitles the Commissioner to allocate the administrative overpayment to the RBA but not the GIC. The GIC on the RBA then becomes payable under s 8AAZF not s 8AAZN(2). The ATO accepts the Court's decision. The ATO says that it will continue to allocate administrative overpayments to RBAs, and to calculate GIC on such administrative overpayments from the date of the overpayment where it has been posted to an RBA.

The ATO has also published a Decision Impact Statement in relation to the District Court of South Australia decision in FCT v De Angelis  SADC 103. The case concerned the same issue as Smith but came to the contrary conclusion. The Commissioner disagrees with the findings in De Angelis and, as indicated above, considers the approach is Smith to be the better approach.
