Ontario SCJ · Jun 26, 2026

Why this matter is tracked
In an appeal before the Ontario Superior Court of Justice, the appellant admitted to using artificial intelligence to prepare his factum. The court identified that the factum contained multiple AI-generated 'hallucinations,' including references to non-existent cases, mischaracterizations of existing authorities, and fabricated quotations. Furthermore, the factum failed to provide pinpoint citations for authorities. The court noted that these failures wasted judicial and party resources. While the appeal was dismissed primarily due to the appellant's failure to perfect the record and reliance on factual arguments without trial transcripts, the court explicitly stated that the appellant's irresponsible use of AI would be taken into account when determining the final costs award against him.
