Avianca, Inc., one of the first significant federal cases on the topic, was not published until June 22, 2023. 678 F. Supp. 3d 443 (S. D. N. Y. 2023). reflects the proliferation of generative Al, its infiltration into legal writing, and its repeated misuse by attorneys. The Mata court aptly explains the harm perpetrated by Scott and Hewitt, and why sanctions are appropriate: Case: 3:25-cv-00273-WHR-CHG Doc #: 122 Filed: 02/25/26 Page: 8 of 14 PAGEID #: 2096 Many harms flow from the submission of fake opinions. The opposing party wastes time and money in exposing the deception. The Court's time is taken from other important endeavors. The client may be deprived of arguments based on authentic judicial precedents. There is potential harm to the reputation of judges and courts whose names are falsely invoked as authors of the bogus opinions and to the reputation of a party attributed with fictional conduct.

The volume of subsequent cases citing Mata and Wadsworth reinforce this Court's conclusion: that the problem of attorneys submitting hallucinated citations is rapidly worsening, and is one of the biggest threats currently facing federal civil litigation. Importantly, the January 2, 2026, Decision made clear that the Court's expectation of accurate citations has no exception for generative Al. Courts have imposed monetary sanctions for attorneys filing Al- hallucinated citations ranging between $1, 000 and $5, 000. Wadsworth, 348 F. R.
