Zhang v. Chen

BC Supreme Court · Feb 20, 2024

Direct answer

What happened in this matter?

The BC Supreme Court ordered counsel to personally pay costs incurred by the opposing party due to the inclusion of AI-generated fake citations in court filings. The court determined that while the lawyer lacked intent to deceive, the conduct constituted an abuse of process and necessitated a remedial review of all the lawyer's active files.

Why the court cared
The court reasoned that citing fake cases is an abuse of process and tantamount to a false statement. However, it found no intent to deceive, noting the lawyer was naive about AI risks and took corrective steps. Costs were awarded under R. 16-1(30) because the lawyer's neglect caused the opposing party to incur unnecessary expense, rather than as a punitive special costs award.
Why it matters now
BC Supreme Court equated fake AI citations with making a false statement to the court - costs attach and careers follow.

Why this matter is tracked

In a family law proceeding, counsel for the respondent included two non-existent case citations in a notice of application, which were generated by ChatGPT. Opposing counsel discovered the citations were fabricated and requested verification. Counsel for the respondent admitted the error, attributing it to a lack of knowledge regarding AI risks and a failure to verify the output. The BC Supreme Court found the inclusion of fake cases to be an abuse of process and tantamount to a false statement to the court. While the court declined to award special costs, finding no intent to deceive, it ordered the lawyer to personally pay costs incurred by the claimant due to the investigation of the fabricated authorities and mandated a review of all pending files.
