Ren v. Area 09
BCPAAB · Oct 7, 2025
What happened in this matter?
The Board found the Appellant breached its Code of Conduct by submitting fabricated case law and failing to disclose the use of generative AI. The Board determined the Appellant’s valuation arguments were unsupported and invited further submissions to decide on a monetary cost order against the Appellant for the resources expended to address the inaccuracies.
- Why the court cared
- The Board reasoned that the Appellant's reliance on non-existent case law and misrepresented standards, whether accidental or intentional, violated the Code of Conduct. The Board emphasized that the Code requires accuracy and the disclosure of AI usage, and that the resulting need for the Board and Assessor to investigate the falsehoods warranted consideration of a cost order under Rule 21(1).
- Why it matters now
- BC PAAB imposes nominal costs and code-of-conduct breaches on pro-se AI users; expect monetary follow-on.
Why this matter is tracked
In a property assessment appeal, the Appellant submitted legal arguments relying on multiple fabricated case law citations and misrepresented international valuation standards. The Board identified that the cited decisions did not exist and noted the Appellant failed to disclose the use of generative AI in preparing the submission. The Board concluded that the Appellant breached the Board’s Code of Conduct, which prohibits inaccurate or misleading submissions and mandates disclosure of AI usage. The Board found the Appellant’s valuation methodology lacked a reasonable basis and invited further submissions regarding potential cost orders against the Appellant for the time spent by the Board and the Assessor in addressing the falsified materials. A subsequent decision will determine the specific monetary costs.
