Bathsheba Nichole Adams v. Kiewit Infrastructure West Company, et al.
U.S. District Court for the District of Arizona · Arizona · Apr 29, 2026
Fabricated: Case Law | Plaintiff cited “Ellsworth v. Am. Arbitration Ass'n, 148 Ariz. 17, 19 (App. 1985),” which the Court found does not exist; the Court identified a likely intended real case as Ellsworth v. Am. Arb. Ass'n, 148 P.3d 983 (Utah 2006) (arbitration issue). || Fabricated: Case Law | Plaintiff cited “Aguilar v. ASARCO” at 780 F.3d 1101 as a Ninth Circuit case; the Court noted no such Ninth Circuit opinion exists and that 780 F.3d 1101 corresponds to Lary v. Trinity Phys. Fin. & Ins. Services (11th Cir. 2015).

U.S. District Court for the District of Arizona · Arizona · Oct 29, 2025

Thompson v. Commissioner of Social Security Administration
U.S. District Court for the District of Arizona · Arizona · Sep 5, 2025
The court granted Plaintiff's motion to strike portions of the Opening Brief after Defendant raised concerns that the brief included a non-existent quotation attributed to an existing case, a mischaracterization of an existing case, a citation to a non-existent case, and a miscitation of a case that did not address the asserted issue. The court noted counsel had been sanctioned in a separate case for citation-related deficiencies consistent with AI-generated hallucinations. The stricken portions were removed and the ALJ decision was affirmed.
