Direct answer

What happened in this matter?

The court found that the defendant relied on AI-generated legal advice that contained 'hallucinations juridiques' and erroneous interpretations of case documents. The court explicitly discredited these submissions, characterizing the defendant's reliance on them as abusive and ill-founded, and ultimately granted the plaintiff's motion for an injunction to enforce the share sale.

Why the court cared
The court reasoned that the defendant's reliance on AI-generated advice was 'erronément et de manière abusive' (erroneous and abusive) and that the AI tools produced 'hallucinations juridiques' and an 'interprétation erronée et mal fondée' of the submitted documents, which exacerbated the defendant's unfounded fears regarding the transaction.
Why it matters now
This case illustrates the risks of pro se litigants relying on AI tools for legal research. It demonstrates how courts identify and reject AI-generated 'hallucinations' that misinterpret case facts and legal obligations, leading to adverse judicial outcomes.

Why this matter is tracked

In a dispute regarding a share purchase agreement, the Superior Court of Quebec addressed the defendant's refusal to finalize the transaction. The court found that the defendant, acting pro se, relied on erroneous legal advice generated by artificial intelligence tools. The court identified numerous 'hallucinations juridiques' within the documentation submitted by the defendant, noting that these AI-generated materials provided an erroneous and ill-founded interpretation of the case documents. The court concluded that the defendant's reliance on these tools was abusive and contributed to a groundless refusal to fulfill contractual obligations. Consequently, the court granted the plaintiff's request for an interlocutory injunction, ordering the defendant to sign the closing documents or face a court-ordered execution of the sale.
