Why this matter warrants attention
The Tribunal refused the Applicant's applications for cost-related relief and fee reimbursement, citing the Applicant's reliance on AI-generated legal hallucinations—including fabricated regulatory text and non-existent case law—as a primary reason for the denial of these discretionary orders.
The Tribunal reasoned that the Applicant's applications for cost protection and fee reimbursement should be refused because the Applicant was unsuccessful, had misunderstood the law, and relied on inaccurate statements originating from AI hallucinations, including false quotes of legislation and non-existent or irrelevant case law.
This case illustrates the risks of using AI for legal research without verification. The Tribunal's explicit reliance on the Applicant's use of AI-generated hallucinations to deny discretionary cost and fee applications highlights the potential for professional and procedural prejudice when AI-generated content is submitted to a court.
