DTMP and Commissioner of Taxation (Taxation)

The Administrative Appeals Tribunal considered a request by DTMP to expand the grounds of its application concerning primary tax and a procedural request, alongside a request to expand grounds concerning penalty. The Tribunal was asked to determine whether to grant these requests.

The legal issues before the Tribunal were whether to allow an expansion of the grounds of the application relating to primary tax, whether to allow a procedural request, and whether to allow an expansion of the grounds of the application relating to penalty.

The Tribunal applied principles derived from case law, particularly from *Hunter Valley Developments Pty Ltd v Cohen*, concerning the exercise of discretionary powers to extend statutory time limits. These principles include the need for an acceptable explanation for any delay, the fairness and equity of granting an extension, the relevance of actions taken by the applicant other than formal application, and the potential prejudice to the respondent. The Tribunal also considered the merits of the substantial application and broader public interest considerations.

The Tribunal declined both the Grounds Expansion Request concerning primary tax and the Procedural Request. However, the Grounds Expansion Request concerning penalty was allowed.
