The lawyers who admitted to using fake case citations generated by ChatGPT in a court filing will have to pay $5,000 in fines and reach out to each judge falsely identified as an author of the fake filings, U.S. District Court Judge Kevin Castel of the Southern District of New York ordered in a 34-page opinion Thursday.

Castel found that Steven Schwartz of Levidow, Levidow & Oberman and his associate Peter LoDuca acted in bad faith when they made false statements to the court, but he did not order the attorneys to apologize, noting that "a compelled apology is not a sincere apology."
