National Indigenous Fisheries Institute v. Canada AG
Federal Court · Mar 20, 2026
What happened in this matter?
The Federal Court of Canada sanctioned the applicant with an adverse costs order after counsel submitted an affidavit containing multiple AI-hallucinated case citations. The Court held that counsel failed to verify the authorities and neglected the mandatory disclosure of AI usage, constituting a serious breach of professional standards and a failure to adequately supervise legal research.
- Why the court cared
- The Court reasoned that citing fake cases is an abuse of process and tantamount to making a false statement to the court. It emphasized that lawyers have a non-delegable duty to verify the accuracy of all authorities submitted, regardless of whether research was subcontracted or AI was utilized. The Court noted that the failure to comply with the AI Practice Direction and the lack of due diligence wasted judicial resources and undermined the integrity of the justice system.
- Why it matters now
- In-house counsel affidavits get no pass; every cited authority in sworn evidence must be independently verified.
