Summary

Plaintiffs' counsel Keith Mathews filed an anti-SLAPP motion containing citations to nonexistent cases, including Klein v. Cheung, 20 Cal. App. 5th 1045 (2018), and a fabricated quotation attributed to Hall v. City of Los Angeles, 697 F.3d 1059 (9th Cir. 2012). Mathews also submitted a 20-page petition exhibit to the Court three times that he later admitted was generated in full by ChatGPT in roughly ten minutes from a single prompt, with under fifteen minutes of human review. Judge Edward M. Chen found these filings, along with a complaint barred by res judicata, violated Rule 11(b)(2) and (b)(3).

What sanction did the court impose?

The Court found Rule 11 sanctions warranted against Plaintiffs and counsel Keith Mathews and ordered Apple to submit declarations and time sheets documenting reasonable attorney's fees and costs incurred as a direct result of the sanctionable conduct, with the fee award to be set after that submission. The Court denied Apple's separate requests to revoke Mathews' pro hac vice admission and to declare Plaintiffs, Dr. Jeffrey Isaacs, and Mathews vexatious litigants, holding that such relief required a properly noticed motion.

Why does Coronavirus Reporter Corporation v. Apple Inc. matter for law firms using AI?

The order is notable for two reasons a managing partner should track. First, the sanctioned attorney candidly disclosed that ChatGPT drafted a 20-page filed exhibit in roughly ten minutes and that his own review took under fifteen, framing it as a “legal experiment”; the Court treated that disclosure as direct evidence that no reasonable Rule 11 inquiry occurred. Second, the same response brief defending against sanctions itself contained a fabricated quotation, illustrating how AI-introduced citation defects tend to compound across successive filings once the verification habit breaks down.
