Attorney Steven Schwartz was sanctioned by a federal judge after submitting a legal motion containing six fabricated court cases generated by ChatGPT. The incident, which occurred in Mata v. Avianca, Inc., represents a documented instance of an attorney using generative AI to create false legal precedent for submission to the court. The court imposed a $5,000 fine against Schwartz and his law firm for the breach.
The fraud was identified when opposing counsel reviewed the motion and discovered discrepancies in the cited cases. None of the six legal citations existed in any court database or official legal record. The opposing party escalated the issue, prompting judicial investigation and ultimately sanctions against the filing attorney.
According to disciplinary findings, Schwartz used ChatGPT for legal research and failed to verify the output before filing. The underlying misconduct stemmed from incompetence and failure to validate the AI system's generated content—a critical procedural gap that resulted in false evidence being presented to the court.
This case is not isolated. In a separate matter, a federal judge in Oregon sanctioned two lawyers $110,000 after they submitted legal filings containing 23 fabricated citations and eight invented quotations. Both incidents underscore a pattern: attorneys deploying AI tools without verification protocols create exposure to sanctions and disciplinary action.
The sanctions impose financial penalties and create precedent for judicial response to AI-assisted document fraud. Courts are establishing that attorney use of unverified AI-generated content—particularly false legal citations presented as real precedent—constitutes actionable misconduct subject to monetary penalties and potential professional discipline.
The Schwartz case signals that judges will hold attorneys accountable when AI outputs are submitted without validation. The $5,000 fine, while modest compared to the Oregon sanction, establishes that courts view AI-generated false citations as a serious breach requiring corrective action.
These rulings create enforceable expectations: attorneys must verify all content generated by AI systems before court filing. The incidents demonstrate that generative AI hallucinates false information at scale, and attorney reliance on unverified AI outputs exposes both individual practitioners and firms to sanctions. Courts are treating this as a matter of professional competence—not a technical limitation to be excused, but a duty breach to be penalized.
