- Observed outcome

- Known monetary consequence
- CA$6,000
Why this matter warrants attention
The court found that the self-represented plaintiff used generative AI to prepare a brief, resulting in the inclusion of non-existent case citations. The court concluded this violated Nova Scotia court guidelines on AI integrity, wasted judicial and opposing counsel resources, and constituted litigation misconduct, justifying an award of costs to the defendant.
The court reasoned that the plaintiff's failure to cross-reference AI-generated citations against authoritative databases (like CanLII) violated court-published AI integrity notices. The judge determined that the errors were not clerical, as the fabricated cases did not support the legal principles asserted, and the complexity of the errors indicated AI generation. The court emphasized that self-represented litigants are expected to adhere to these verification standards, and the resulting waste of resources justified a costs award.
This case illustrates the application of specific court-mandated AI verification protocols to self-represented litigants. It confirms that courts will impose costs when AI-generated hallucinations increase the research burden on opposing parties, regardless of the litigant's pro se status.
