HRT Ontario · Oct 9, 2025
What happened in this matter?
The Tribunal deferred the application pending the outcome of a union grievance. While the applicant cited three nonexistent cases, the Tribunal's decision to defer was based on the procedural overlap between the human rights application and the ongoing labour arbitration, rather than a sanction for the fabricated citations.
- Why the court cared
- The Tribunal found the grievance and human-rights application overlapped enough that proceeding in parallel could create conflicting determinations, so deferral was fair and efficient.
- Why it matters now
- The decision separates the citation problem from the merits and shows that fabricated authority can undermine a party's submissions even where a procedural disposition is independently justified.
Why this matter is tracked
Paul Visca filed a Human Rights Tribunal of Ontario application alleging employment discrimination based on disability after the Halton District School Board terminated him following a sexual-harassment investigation. His representative cited three decisions that the Tribunal said did not appear to exist. The Tribunal deferred the application because an ongoing union grievance and arbitration concerned sufficiently similar events, not because it accepted the defective authorities. The claimant was a teacher, and the union grievance challenged the termination as excessive discipline.
HRTO applicants citing phantom cases face exclusion of authorities; CanLII verification is non-negotiable.
