Why this matter is tracked
In a tax penalty appeal before the Administrative Review Tribunal of Australia (ARTA), the pro se applicant submitted closing arguments relying on two case citations: 'Cheung v FCT [2021] AATA 3851' and 'Dwyer v FCT [2018] AATA 456'. The Tribunal and the Commissioner of Taxation determined that these cases do not exist and that the applicant's cited legal principles were incorrect. The Tribunal noted that it suspected the use of artificial intelligence in the preparation of the applicant's submissions, citing a prior decision, 'Smith and Commissioner of Taxation [2026] ARTA 25', to emphasize the necessity of verifying AI-generated research against public databases. The Tribunal ultimately set aside the Commissioner's decisions regarding shortfall penalties and remitted the matter for reassessment.
