Rigoli v Commissioner of Taxation

In the case of Rigoli v Commissioner of Taxation, the applicant, Mr Rigoli, appealed against a decision of the Administrative Appeals Tribunal (AAT) that dismissed his objections to a default assessment of income tax made by the Commissioner of Taxation. The default assessment was issued after Mr Rigoli failed to lodge tax returns for the relevant period. The AAT had determined that the default assessment was valid and that Mr Rigoli had not discharged the onus of proving that the assessment was excessive.

The legal issues before the court were whether the appeal was incompetent and if the appeal raised a question of law. Additionally, the court had to consider whether the AAT was required to go beyond the material produced by the parties and conduct its own investigation, and if Mr Rigoli could rely on an expert report prepared for the Commissioner to establish that the assessment was excessive.

The court held that the appeal was not incompetent and did raise a question of law. It was determined that the AAT was not required to go beyond the material produced by the parties and conduct its own investigation. The court found that the AAT had erred in its consideration of the expert report, as it was not bound to accept the Commissioner's evidence without question. However, the court also held that Mr Rigoli had not discharged the onus of proving that the default assessment was excessive, and therefore the appeal was dismissed. The probative value of the expert report was found to be insufficient to establish the taxpayer's taxable income.

The final orders of the court were that the appeal was dismissed, and the decision of the AAT was affirmed. The court found that the AAT had not erred in law and that Mr Rigoli had not discharged the onus of proof to establish that the default assessment was excessive.
