Greig and Commissioner of Taxation (Taxation)

This matter concerned an application by Mr Greig before the Administrative Appeals Tribunal (AAT) in relation to a decision by the Commissioner of Taxation. The precise nature of the dispute, beyond its relation to a taxation assessment, is not detailed in the provided text.

The primary legal issue before the Tribunal was whether Mr Greig's application, which may have been valid at its inception, had become misconceived or lacking in substance due to a subsequent event. This required the Tribunal to consider the impact of events occurring after the lodgement of an application on its continued viability.

The Senior Member determined that while Mr Greig's application was not misconceived or lacking in substance when it was initially filed, the subsequent issuing of a notice of amended assessment had rendered it so. This indicates an application of principles concerning the temporal relevance and continuing validity of applications in administrative review processes, particularly where the underlying subject matter of the dispute has been altered by a subsequent official action.
