Why this matter warrants attention
The Court ordered counsel for the petitioner to file a declaration under penalty of perjury explaining the inclusion of fabricated case law quotations in a motion to quash. The Court identified these errors after the opposing party highlighted them and counsel failed to provide an explanation during oral argument.
The Court found the motion contained multiple fabricated quotations that did not exist in the cited authorities. Counsel's inability to explain these errors during the hearing led the Court to order a formal declaration under penalty of perjury to address the misconduct.
This case highlights judicial scrutiny of filings containing fabricated case law. It demonstrates that courts may require formal, sworn explanations from counsel when AI-generated or otherwise hallucinated citations are presented in motions, regardless of whether the underlying motion is otherwise denied.
