A Canadian judge has ordered a family law lawyer who submitted fake ChatGPT-generated cases to the court to personally pay the costs of the time opposing counsel spent trying to verify them.

“Citing fake cases in court filings and other materials handed up to the court is an abuse of process and is tantamount to making a false statement to the court. Unchecked, it can lead to a miscarriage of justice,” said British Columbia Supreme Court Justice David Masuhara.
