Song Dow Lee, et al. v. HSBC Bank USA, National Association, et al.
C.D. California · May 7, 2026
What happened in this matter?
The court issued an Order to Show Cause requiring plaintiffs' counsel to explain why they should not be sanctioned $2,500 or have the case dismissed for submitting fabricated citations and misrepresenting case law. The court explicitly ordered counsel to disclose whether AI was used in drafting the filings and to detail their verification process for the cited legal authorities.
- Why the court cared
- The court reasoned that counsel's inclusion of non-existent citations and misrepresentation of case law, which persisted even after being flagged by the opposing party, necessitated an inquiry into the drafting process and the adequacy of counsel's research verification.
- Why it matters now
- This case highlights the judicial response to the submission of AI-generated or poorly verified legal research. It underscores the court's expectation that counsel must independently verify the existence and accuracy of all cited authorities, regardless of the drafting tools employed.
