What happened
Christopher M. Cervantes, principal of Cervantes Law, P.C. and counsel for plaintiff Vita Law Offices, told the court he inadvertently used Microsoft Copilot, an AI-based tool, which altered quoted language in case citations. His own review found eighteen errors across the filings: misattributed quotes, incorrect citations, and clerical oversights. He apologized to the court and opposing counsel and proposed completing AI and legal-ethics education courses. His first response (ECF No. 26) identified thirteen errors; after the court found it inadequate, his supplemental response (ECF No. 28) identified five more.
The rule and the sanction
The court issued an Order to Show Cause over the fabricated quotations, found counsel's first response inadequate (Dkt. 27, July 16, 2025, it understated fabricated quotes as "Paraphrase/summarization, not verbatim" and omitted further errors), and resolved the matter by final order (Dkt. 30, July 23, 2025) requiring counsel to complete four CLE courses within 60 days, on topics such as the use of AI in legal practice, legal ethics, and federal practice, and to file a signed declaration detailing the course titles, providers, completion dates, and the key lessons from each; no monetary sanction was imposed. Attorney: Christopher M. Cervantes. Sources: ECF No. 28 (supplemental response); https://www.law.com/2025/07/23/boston-lawyer-faces-sanctions-after-ai-tool-generated-nightmare-of-mistakes/ (reporting the judge's ruling that the matter was resolved after counsel completed CLE courses and filed a declaration of compliance).
How it could have been avoided
Never run an AI editing tool over brief text without re-verifying every quotation against the original opinion. Compare each cited quotation character by character before filing.
