Why this matter warrants attention
The appellant, a pro se litigant, admitted to using AI to prepare for his tax appeal. This resulted in the submission of four fabricated case law citations. The Tribunal identified these as non-existent, recorded the incident for the record, and proceeded to decide the case on its merits, ultimately allowing the appeal.
