Van Irion and Russ Egli cited over two dozen nonexistent cases in federal court briefs, prompting the Sixth Circuit to impose $15,000 in fines plus double costs and opponent attorney fees in Whiting v. City of Athens. The lawyers' fabricated citations weren't typos or sloppy research — they were wholesale inventions that Judge John Bush called "fake citations" requiring independent verification by court staff.
The sanctions represent the judicial system's growing impatience with lawyers who treat generative AI as a research shortcut rather than a tool requiring human oversight. Courts nationwide have witnessed a surge in fictitious case citations since ChatGPT's launch, forcing judges to become fact-checkers rather than legal arbiters. The Sixth Circuit's harsh penalty signals that the honeymoon period for AI-assisted legal malpractice has ended.
When ordered to explain their misconduct, Irion and Egli compounded their offense by refusing compliance entirely. They claimed the court's show-cause order was "void on its face" because the clerk signed it rather than an Article III judge — a procedural objection the Supreme Court had already rejected twice in separate mandamus petitions from the same lawyers. Their defiance transformed a professional mistake into willful contempt.
The court's response reveals how fabricated citations poison the entire adversarial process. Judges must now independently verify every case cited by these lawyers in future proceedings, while opposing counsel faces inflated costs checking citations that should be reliable. The sanctions acknowledge that legal practice depends on baseline trust — when lawyers lie about controlling precedent, the system's foundation crumbles.
Missing from this decision is any explanation of which AI tool generated the fake cases or how widespread similar misconduct might be across other circuits. The court noted this was a "conservative estimate" of fabrications, suggesting systematic problems in how lawyers integrate generative AI into legal research. Without industry-wide disclosure requirements for AI assistance, similar sanctions remain inevitable rather than deterrent.
The Sixth Circuit's punishment creates a precedent other courts will likely follow: double costs under Federal Rule 38 combined with inherent authority fines and attorney fee awards. This multi-pronged approach ensures that AI-assisted fabrication becomes financially ruinous rather than merely embarrassing, potentially forcing law firms to implement verification protocols they should have adopted voluntarily.
