Gu v Fogler Rubinoff
SCJ Ontario · Jan 23, 2026
What happened in this matter?
The court denied the applicant's request for costs despite granting the motion to set aside the administrative dismissal. The decision-maker explicitly penalized the applicant for submitting a factum containing fabricated case law and quotations generated by AI, which the court characterized as unacceptable conduct.
- Why the court cared
- Fabricated: Case Law | Applicant's factum included at least two fully cited cases and quoted passages that could not be located; responding party brought this to court's attention; applicant's daughter conceded they were created by AI. || Fabricated: Case Law | One or more quoted passages attributed to cited cases were false because the underlying cases did not exist; court treated submission as misconduct and denied costs.

Why this matter is tracked
In a motion to set aside an administrative dismissal of a fee assessment, the applicant submitted a factum containing fabricated case law and quotations. The respondent identified that at least two cited cases could not be located. The applicant's daughter, who drafted the factum, admitted the citations and quotes were generated by AI to support the applicant's position. The applicant subsequently withdrew the factum. While the court granted the motion to restore the assessment, finding the delay was largely attributable to the respondent's prior request for a stay, the court denied the applicant's request for costs, citing the submission of fabricated legal authorities as unacceptable conduct.
