Why this matter warrants attention
The Fifth Circuit admonished a pro se litigant for citing multiple nonexistent authorities in appellate briefing, which the court attributed to the use of generative AI. The court warned the litigant that continued submission of fabricated authorities and repetitive, frivolous filings could result in future sanctions.
The court reasoned that the litigant's citation to nonexistent authorities violated the duty of accuracy and suggested the use of generative AI, warranting an admonition under appellate rules regarding frivolous filings.
This case illustrates judicial scrutiny of AI-generated hallucinations in pro se appellate filings. It reinforces the universal obligation for all litigants to verify the existence and accuracy of cited authorities, regardless of the research tools employed.
