Summary

Roberto Mata sued Avianca in New York state court on February 2, 2022, over a knee injury from a serving cart on a 2019 flight; Avianca removed the case to the Southern District of New York on February 22, 2022. Opposing Avianca's motion to dismiss, Mata's lawyers filed papers citing judicial opinions that did not exist, which one lawyer had obtained from ChatGPT, and they kept standing by them after the court questioned them. On June 22, 2023, Judge P. Kevin Castel sanctioned attorneys Peter LoDuca and Steven Schwartz and their firm, Levidow, Levidow & Oberman, imposing a $5,000 penalty jointly and severally and requiring letters to the client and to the judges falsely named as authors. The same day he dismissed the claim as untimely under the Montreal Convention's two-year limit, and judgment for Avianca was entered on July 7, 2023. The docket shows no later filings.
