Sarah & Regina Alonso v. Jackson

W.D. Washington · Mar 17, 2026

Direct answer

What happened in this matter?

The court issued a formal warning to plaintiffs' counsel regarding the citation of a non-existent case, 'Allen v. Bayshore Mall.' The court explicitly cautioned that the submission of fictitious legal authority is sanctionable under Rule 11 and warned that it would issue an order to show cause if counsel again submitted such material.

Why the court cared
The court reasoned that citing non-existent case law constitutes a false statement to the court, which is sanctionable under Rule 11. It observed that the inability to locate the cited 'Allen v. Bayshore Mall' suggested improper oversight of generative AI or similar text-generation tools.
Why it matters now
One fabricated citation in a motion to amend earns a Rule 11 warning on the docket; verify before you sign, not after the court flags it.
