For one of the cases, Varghese v. China Southern Airlines, lawyers for Avianca said they had “not been able to locate this case by caption or citation, nor any case bearing any resemblance to it”.
Ordering a hearing for June 8 to discuss potential sanctions, Castel said a clerk had confirmed the docket number on the opinion was connected to a separate case.

Schwartz said in an affidavit filed on Thursday that he had consulted ChatGPT “to supplement” his own work.
In screenshots supplied with the submission, the lawyer was seen asking the AI programme whether the cases cited were “fake”.
He asked if one of the opinions referenced was “a real case”. The chatbot replied confirming it was and provided a citation.

ChatGPT responded: “No, the other cases I provided are real and can be found in reputable legal databases.”
Schwartz said he had used the AI tool to do his research, which he described as “a source that has revealed itself to be unreliable”.
The lawyer said he had never used ChatGPT for his research before and “therefore was unaware of the possibility that its content could be false”.
He told Castel he “greatly regrets” his actions. Schwartz said he had no intent to deceive the court or the airline and will not use the tool in the “future without absolute verification of its authenticity”.
Schwartz was approached for comment on Saturday.
