Robinson v. Oglala Sioux Tribe
U.S. District Court, Western District of Oklahoma · W.D. Okla. · Oklahoma bar guidance
Conduct
Pro se filings included non-existent legal authority, violent threats, and fabricated evidence; plaintiff argued AI use is not prohibited.
Consequence
Action dismissed with prejudice under inherent authority; monetary sanctions deemed ineffective due to in forma pauperis status.
Lesson
Rule 11 obligations are not altered by AI; AI-misrepresented authority compounds with non-AI misconduct to justify the harshest sanction.

Summary
Pro se Plaintiff Shantell Robinson brought a multi-defendant action in the Western District of Oklahoma that accumulated over 100 filings in its early stages, the vast majority filed by Plaintiff. After warnings from the Court that further failure to comply with procedural rules could result in sanctions including dismissal, Defendants Wakpamni Lake Community Corporation, Raycen Raines, and John Read moved for sanctions citing four categories of misconduct: (1) threatening correspondence to Defendants and their counsel, including text messages stating "I am prepared to end his life if he invades my space" and "if one of you fall you all get buried"; (2) submission of fabricated evidence, including a photograph Plaintiff later admitted was not authentic and quoted statements attributable to defense counsel that counsel swore under oath never occurred; (3) submission of non-existent and misrepresented legal authority across multiple filings (Docs. 68, 79, 80, 103); and (4) excessive and frivolous filings, including motions citing symptoms such as "burning, itching, and pressure in ears, ribs, and back of scalp matching DOJ's coded digital harassment symptom matrix." Plaintiff defended her filings by arguing that her use of artificial intelligence to assist with the litigation was not prohibited.
- AI tool:
- Generative AI (specific tool not identified on the record; Plaintiff's filings repeatedly contained non-existent and misrepresented legal authority)
- Sanction amount:
- Dismissal with prejudice
What sanction did the court impose?
Chief Judge Timothy D. DeGiusti found that Defendants proved each category of misconduct by clear and convincing evidence and that the King v. Fleming five-factor analysis weighed in favor of the most severe sanction. Action dismissed with prejudice as a sanction under the Court's inherent authority. The Court noted that because Plaintiff was proceeding in forma pauperis, monetary sanctions would be ineffective. The Court applied Coomer v. Lindell and the Tenth Circuit's Mata-line authority to hold that "[a] party's obligations under Rule 11 are not altered by the technology a party uses in preparing a filing submitted to the Court."
Why does Robinson v. Oglala Sioux Tribe matter for law firms using AI?
Robinson is the W.D. Oklahoma chambers cluster’s first 2025 AI-citation order from Chief Judge Timothy D. DeGiusti, three months before the same chambers’ Hill v. Oklahoma County Criminal Justice Authority order on December 4, 2025. The two cases share a pattern: pro se or attorney misconduct involving AI-generated citations, layered on top of independent sanctionable conduct, culminating in a tailored remedial sanction. In Robinson the sanction is dismissal with prejudice; in Hill it is monetary, CLE, and prospective AI-disclosure obligations.
Robinson should be cited carefully. The dismissal is justified primarily by the threats of physical violence to Defendants and their counsel, with fabricated evidence and AI-misrepresented authority as compounding factors. It is not a “pure” AI-citation dismissal, and citing it as one would overstate its reach. The durable AI-specific holding is the Court’s adoption of the Coomer v. Lindell framing: “A party’s obligations under Rule 11 are not altered by the technology a party uses in preparing a filing submitted to the Court.” That language responds directly to Plaintiff’s argument that her AI use was not prohibited, and it is the kind of rebuttal sentence that defending counsel should expect to see and to brief in any case where a pro se filer raises a similar defense.
For a managing partner, two operational takeaways. First, the Robinson order documents the W.D. Oklahoma DeGiusti chambers’ willingness to reach for the harshest available sanction when AI misconduct compounds with other Rule 11 violations; firms with matters before that chambers should treat AI-citation hygiene as a baseline expectation, not an aspiration. Second, the in-forma-pauperis posture forecloses monetary sanctions as a deterrent, which means courts will reach for non-monetary sanctions (dismissal, filing bans, prospective disclosure orders) earlier in IFP cases. Defendants should plan their sanctions strategy accordingly when responding to AI-generated filings from indigent pro se plaintiffs.
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.
- When a pro se plaintiff defends fictitious citations by arguing AI use is permitted, the response is structural: the obligation under Rule 11 attaches to the filing, not to the technology used to generate it. Brief this point in any sanctions opposition.
- Dismissal with prejudice as an AI-citation sanction remains rare in 'pure' citation cases but is available when AI misconduct compounds with other sanctionable conduct (threats, fabricated evidence, frivolous filings). Defending counsel building a sanctions record should document each category separately.
- The case is the second 2025 W.D. Oklahoma DeGiusti chambers AI-citation order, paired with Hill v. Oklahoma County Criminal Justice Authority (Dec. 4, 2025). Firms with W.D. Okla. matters should treat the chambers as having a documented willingness to issue AI-related sanctions.
- In forma pauperis status forecloses monetary sanctions as a meaningful deterrent; courts will reach for non-monetary sanctions (dismissal, filing prohibitions, prospective disclosure orders) earlier when the plaintiff is IFP.
