Villasenor v. Ralphs Grocery Company

Superior Court of California, County of Los Angeles, South Central District (Compton Courthouse) · Cal. Super. Ct. (L.A. Cnty.) · California bar guidance

Conduct

Here the plaintiff's opposition cited a federal case, "Bilo v. Dept. of Defense," that the court, as the defendant pointed out in reply, said does not exist.

Consequence

None for the citation: no sanction, warning or order to explain. The court granted summary adjudication for Ralphs on seven of nine causes of action.

Lesson

Here the opposing party caught the citation in its reply, and the court recorded in one sentence that the case does not exist before deciding the motion.

Citation
Villasenor v. Ralphs Grocery Company, No. 23CMCV02044, Minute Order (Ruling on Submitted Matter) (Cal. Super. Ct. L.A. Cnty. Oct. 28, 2025) (Wilson, J.)
Decided
October 28, 2025

Summary

Miguel Villasenor, who alleged he had worked for Ralphs Grocery Company for about 29 years, sued after Ralphs terminated him following two 2023 altercations with a coworker, asserting among other claims disability discrimination, failure to accommodate, failure to engage in the interactive process and retaliation under FEHA. Ralphs moved for summary judgment or summary adjudication, arguing among other things that it never knew of his alleged, undiagnosed mental disability. In his opposition, filed six days late but considered by the court, the plaintiff cited cases for the proposition that an employer can be charged with knowledge of an undiagnosed disability it observes or learns of from a third party. The first was "Bilo v. Dept. of Defense (D. Haw. 2010) 720 F. Supp. 2d 1267." The court wrote: "As pointed out by Defendant in its reply, this case does not exist." It found that another cited case, Faust v. California Portland Cement Co., does state that standard but is factually distinguishable, and that Taylor v. Phoenixville School Dist. "does exist" but is distinguishable too, concluding that the plaintiff "has provided no authority that supports" his position that his behavior was enough to put Ralphs on notice. The ruling does not mention artificial intelligence and does not name the plaintiff's counsel.

How did the court address the AI-related conduct?

In an October 28, 2025 ruling on the motion, which it had taken under submission at the September 10, 2025 hearing, Judge Michael B. Wilson granted summary adjudication for Ralphs on seven causes of action (wrongful termination in violation of public policy, the four FEHA claims, battery, and intentional infliction of emotional distress) and denied it on assault and on negligent supervision and retention. On the FEHA claims the court held that Ralphs had no actual or constructive notice of the alleged disability and that the plaintiff had not shown the stated reason for his termination, the altercations, to be pretextual. On assault and negligent supervision and retention it found triable issues arising from a store manager's failure to report the first altercation to Ralphs's labor relations department. The court's only treatment of the Bilo citation is the sentence recording that, as Ralphs pointed out in its reply, the case does not exist. The ruling imposes no sanction, issues no admonishment or warning, orders no explanation, and makes no referral.

Why does Villasenor v. Ralphs Grocery Company matter for law firms using AI?

Villasenor is an employment case in which the nonexistent citation drew a single sentence. The plaintiff, who said he had an undiagnosed mental disability affecting communication and routine, argued that Ralphs should be charged with knowing about it from coworkers’ and managers’ observations. To support that theory his opposition cited “Bilo v. Dept. of Defense (D. Haw. 2010) 720 F. Supp. 2d 1267.” Judge Wilson wrote: “As pointed out by Defendant in its reply, this case does not exist.”

The court then dealt with the real cases the plaintiff cited on the merits. It accepted that Faust v. California Portland Cement Co. states the standard the plaintiff relied on, but found Faust distinguishable because the plaintiff there had provided a medical provider’s request for a leave of absence; it found Taylor v. Phoenixville School Dist. distinguishable because the employee there had been hospitalized and had given the employer medical notes. The ruling does not mention artificial intelligence, and the Charlotin tracker’s AI coding is an inference the court did not make.

Nothing followed from the citation. The court did not warn or admonish counsel, did not ask for an explanation, and imposed no sanction; it granted Ralphs summary adjudication on most claims and let the assault and negligent supervision claims go forward. Firms documenting compliance may wish to consider that a nonexistent citation can be recorded in a written ruling even when the court takes no further step, and that here the problem was surfaced by opposing counsel’s reply.

Implications for your firm

Operational steps a firm reading this case may wish to consider documenting. Strategic and rule-application calls belong to your firm's attorneys.

  • Verify federal district court citations as carefully as appellate ones. Here the nonexistent authority was presented as a 2010 District of Hawaii decision in the Federal Supplement.
  • Review whether real authorities match the facts argued. Here the court found that two real cases the plaintiff cited, Faust and Taylor, were distinguishable on their facts, and that he had no authority that his behavior was enough to put Ralphs on notice of his disability.
  • Consider that opposing counsel may check the citations and report a missing case in reply. Here Ralphs pointed out that the case does not exist, and the court adopted that point in its ruling.
