Progressive Northern Insurance Company v. Tony Pete Flores, et al.

U.S. District Court, District of Nevada · D. Nev. · Nevada bar guidance

Conduct

Here Defendants' sanctions motions quoted authorities with what the court called fabricated or inaccurate language; Plaintiff moved to strike, citing 11 examples of improper AI use.

Consequence

Defendants' "first and final warning"; the court found fees warranted but denied Plaintiff's undeveloped fee request. Motion to strike denied as moot after the motions were withdrawn.

Lesson

Here withdrawing the flawed motions did not end the matter: the court still addressed the conduct, called it a serious breach, and put Defendants on final warning.

Progressive N. Ins. Co. v. Flores, No. 2:24-cv-02207-RFB-BNW, Order (D. Nev. June 18, 2026) (Weksler, M.J.), ECF No. 120
Decided
June 18, 2026

Summary

In this federal action, Defendants filed two motions for sanctions (ECF Nos. 100 and 101). Plaintiff Progressive Northern Insurance Company responded with a motion to strike that, in the order's words, cited "11 examples of improper AI use in Defendants' motions" (ECF No. 107, appendix). Defendants then withdrew both sanctions motions (ECF Nos. 113 and 114) and responded to the motion to strike (ECF No. 117). Magistrate Judge Brenda Weksler said the court "nonetheless finds it necessary to address the conduct that gave rise to Plaintiff's motion" and wrote: "Counsel's submission of AI-generated content without verifying the accuracy of the cited authorities is a serious breach of several Model Rules of Professional Conduct (competence, diligence, candor, misconduct) and is the type of conduct Rule 11 is intended to prevent." In a footnote the court said Plaintiff "should not have been required to expend time and resources responding to motions that quoted authorities with fabricated or inaccurate language," and that "the notion that a phone call to Plaintiff would have sufficed diminishes the gravity of the situation." The order does not name defense counsel.

What did the court warn about?

The court acknowledged Defendants' representations that they had implemented corrective measures and said it "expects strict compliance with those procedures." It stated: "This Order serves as Defendants' first and final warning. Any future submission containing fabricated or inaccurate citations, or any other AI-generated content that has not been adequately verified may result in sanctions, including referral for disciplinary proceedings." It found "that an award of fees is warranted" but denied Plaintiff's fee request because Plaintiff did not specify the authority for it or argue, or show compliance with, Rule 11. The motion to strike was denied as moot because the challenged motions had been withdrawn, and the June 23, 2026 hearing was vacated. On July 13, 2026 the court issued a further order (ECF No. 126) repeating the warning and the fee ruling and also declining Plaintiff's request to bar Defendants from filing "similar motions," relying on Defendants' stipulation not to refile the sanctions motions. Objections to a magistrate judge's ruling were filed on June 26 (ECF No. 124) and July 27, 2026 (ECF No. 135); their contents were not available.

Why does Progressive Northern Insurance Company v. Tony Pete Flores, et al. matter for law firms using AI?

The order is short, but it separates two questions that often run together. On the conduct, the court did not treat the withdrawal of the challenged motions as the end of the matter. It said it “nonetheless finds it necessary to address the conduct that gave rise to Plaintiff’s motion,” characterized counsel’s submission of unverified AI-generated content as “a serious breach of several Model Rules of Professional Conduct (competence, diligence, candor, misconduct),” and issued Defendants a “first and final warning” that future unverified AI content “may result in sanctions, including referral for disciplinary proceedings.” It also rejected, in a footnote, the suggestion that a phone call to Plaintiff would have sufficed.

On the remedy, the court was exacting about procedure. It found “that an award of fees is warranted” but denied the request because Plaintiff’s motion did not say whether it rested on Rule 11, 28 U.S.C. 1927 or the court’s inherent power, relied instead on another District of Nevada decision in which fees had been imposed under Rule 11, and neither argued Rule 11 nor showed compliance with its requirements. The later July 13 order kept that result and declined Plaintiff’s broader request to bar Defendants from filing “similar motions,” reasoning that the request was undefined, that Defendants had stipulated not to refile the withdrawn sanctions motions, and that Plaintiff had not shown why barring any reference to the deposition would be tailored to preventing repeated improper AI use.

Firms documenting compliance may wish to consider both sides of this record. For the filer, a withdrawn motion can still produce a written warning on the docket. For the party that catches the errors, the court’s ruling turned on identifying the legal authority for fees, not on whether the errors occurred. The docket also shows objections to a magistrate judge’s ruling filed after each order, which were not available to read; the entry does not say what they challenge.

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 citations in sanctions motions with particular care. Here the challenged filings were Defendants' own motions for sanctions, and the court described them as quoting "authorities with fabricated or inaccurate language."
  • Document corrective measures adopted after a citation problem. Here the court acknowledged Defendants' representations about new procedures and said it "expects strict compliance with those procedures."
  • Review how a fee request tied to AI-generated errors is framed. Here the court found fees warranted but denied them because Plaintiff did not identify Rule 11, 28 U.S.C. 1927 or inherent power as the basis or show compliance with Rule 11's requirements.

Sources

Primary sources

Unverified claims:
  • Which filer objected in ECF Nos. 124 and 135, which ruling each objection challenges, and whether the district judge has ruled on them: the objections are not in the RECAP archive, and the docket entries read on 2026-09-30 (through ECF No. 139, Aug. 10, 2026) show responses and replies but no ruling.
  • Why the court issued the July 13, 2026 order (ECF No. 126): it restates the June 18 order with an added paragraph but does not say whether it amends or replaces ECF No. 120. The intervening July 7, 2026 minute order's text was not available.
  • The specific citations at issue: the order refers to Plaintiff's appendix of 11 examples but does not list them.
