- Observed outcome

- Known monetary consequence
- CA$1,500
Why this matter warrants attention
The Tribunal identified that the applicant's representative cited a non-existent case. The Vice-Chair explicitly warned the representative that submitting materials relying on non-existent cases can lead to cost consequences and strongly encouraged the representative to ensure all future cited cases are real.
Fabricated: Case Law | Representative cited a non-existent Tribunal decision 'Wu v TSCC 1754, 2021 ONCAT 63'; the Tribunal found the case does not exist and warned such citations may incur cost consequences.
Tribunals are now pre-warning fabricators that future hallucinations will draw costs—cite that warning in your own briefs.
