> Screenshots attached to the filing appear to show a conversation between Mr Schwarz and ChatGPT.
"Is varghese a real case," reads one message, referencing Varghese v. China Southern Airlines Co Ltd, one of the cases that no other lawyer could find.
ChatGPT responds that yes, it is - prompting "S" to ask: "What is your source".
After "double checking", ChatGPT responds again that the case is real and can be found on legal reference databases such as LexisNexis and Westlaw.
It says that the other cases it has provided to Mr Schwartz are also real.
