What the court wrote
Verbatim from the court's document (public domain). Ellipses mark omitted text; nothing is paraphrased.
– have a tendency to hallucinate non-existent cases. Sanders v. United States, 176 Fed. Cl. 163, 169 (2025) (“It is no secret that generative AI programs are known to ‘hallucinate’ nonexistent cases, and with the advent of AI, courts have seen a rash of cases in which both counsel and pro se litigants have cited such fake, hallucinated cases in their briefs.”); Raven Investigations & Sec. Consulting, LLC, B-423447, 2025 CPD ¶ 81 at 3 (“[T]he use of AI programs to draft or assist in drafting legal briefs can—and seemingly often does—result in the citation of non-existent cases.”); see also Ralph Nash, Artificial Intelligence Hallucinations: Sanctions are Waiting, 39 NASH & CIBINIC REP. ¶ 44 (Aug. 2025) (“[I]t is well known that so far AI programs tend to hallucinate.”). The real decision near the hallucinated citation is Johns-Manville Corp. v. United States, 12 Cl. Ct. 1 (1987). “Fake cases generated by AI often have reporter citations that lead to cases with different names, in different courts, and about different subjects.” Sanders, 176 Fed. Cl. at 169 n.8. Endure asserts that the Johns-Manville decision supports the assertions made in its brief
