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).
