Kocak v The Commissioner for Act Revenue

In the case of Kocak v The Commissioner for ACT Revenue, the court was asked to consider whether a decision made by the Commissioner for ACT Revenue could be reviewed by the Australian Capital Territory Civil and Administrative Tribunal (ACAT). The dispute arose from a series of objections made by Ms Kocak, who was contesting the tax decisions made by the Commissioner. The Commissioner argued that the decision dated 6 April 2018, which had been set aside by the ACAT, could not be reviewed, and that a subsequent decision dated 4 September 2018 was not a reviewable decision as it was governed by a section of the Taxation Administration Act 1999 that only allows review by the Commissioner. The legal issues before the court were whether the setting aside of the original decision by the ACAT meant there was no reviewable decision to consider, and whether the decision dated 4 September 2018 was indeed a reviewable decision under the relevant statutes.

The court examined the effect of the order to set aside the original decision, noting that such an order rendered the decision inoperative, whether retrospectively or prospectively. It found that once a decision was set aside, it ceased to have effect and thus, no longer constituted a reviewable decision for the purposes of the ACAT. Additionally, the court concluded that the decision dated 4 September 2018 was not a reviewable decision as it was covered by a section of the Taxation Administration Act 1999 that restricts review to the Commissioner. Based on these findings, the court determined that there was no reviewable decision for the ACAT to consider.

The court ordered that the application for review lodged by Ms Kocak on 12 September 2018 be rejected. This decision was grounded in the interpretation of the relevant statutory provisions and the effect of the ACAT's prior orders, which effectively nullified the decisions in question.
