Summary
Kristina Crist sued Canadian County Sheriff Roy Chris West and others over an alleged sexual assault by Wesley Wayne Hunter while he was working as a Canadian County sheriff's deputy. Her counsel, Rachel Bussett, filed an untimely response to the sheriff's partial motion to dismiss that included nonexistent cases and citations to authority that does not stand for the proposition indicated. The court found that although Ms. Bussett suspected the brief contained errors before the court issued its March 10, 2026 show-cause order, she did not notify the court or ask to withdraw the brief. In her written response, she attributed the errors to her use of a "trusted legal vendor's AI tool" to research and draft the brief, along with some "more traditional errors," conceded that she had not personally verified the citations, and apologized. The court heard her explanation at a March 31, 2026 hearing in a separate case before it, Jane Doe 1 v. Mount Saint Mary High School Corp., which it said generally applied here; it struck the separate hearing in this case and took written submissions from both sides instead. Defendants suggested sanctions consistent with those imposed in the Mount Saint Mary case.
- AI tool:
- A "trusted legal vendor's AI tool" (counsel's own description, as quoted by the court; the tool is not named)
- Sanction amount:
- $250 to the Clerk of Court for the general court fund; public reprimand; copy of the order to the client with a filed certification
What sanction did the court impose?
The court found that the inclusion of fake or misleading authority in a written brief violated Rule 11(b)(2). Treating deterrence as the primary goal and seeking the least severe adequate sanction, it imposed three sanctions: the order stands as a public reprimand of Ms. Bussett's conduct; she must give a copy of the order to her client within fourteen days and file a notice certifying compliance; and she must pay $250.00 to the Clerk of Court for the general court fund within thirty days, which the court called "the least severe monetary penalty that will deter and punish the conduct." Quoting Mattox v. Product Innovations Research, the court observed that the conduct "represented a profound failure of professional duty" but "also presents a rare opportunity for public correction rather than professional ruin." In a separate order the same day (ECF No. 25), the court ruled on the partial motion to dismiss and noted that the citation issues would be resolved separately.
Why does Crist v. West matter for law firms using AI?
Crist is the shorter of two orders the same Western District of Oklahoma court issued against attorney Rachel Bussett in May 2026. Her explanation here was that a “trusted legal vendor’s AI tool” produced the problem citations, alongside “more traditional errors,” and she conceded that she “failed to perform the essential step of personally verifying the case citations.” The court did not separately find how the errors arose; it held that “the inclusion of fake or misleading authority in a written brief” violates Rule 11(b)(2), citing Wadsworth v. Walmart.
The order borrows from the court’s handling of the other case. Because Ms. Bussett’s arguments in Jane Doe 1 v. Mount Saint Mary High School Corp. “generally apply to this action,” and that hearing ran long, the court struck the separate Crist hearing and decided on written submissions. Defendants asked for sanctions consistent with Mount Saint Mary. Six days later, the Mount Saint Mary order declined to add a fine there, citing both the discovery fee award it had already decided to make there and the monetary sanction imposed in Crist.
The sanction here is a public reprimand, notice to the client, and $250 to the court fund. Firms documenting compliance may wish to consider the detail the court singled out: counsel suspected errors before the show-cause order issued and still did not tell the court or seek to withdraw the brief.
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.
- Document a correction protocol for filed briefs. Here counsel suspected errors before the show-cause order but, the court found, did not notify the court or request permission to withdraw the brief.
- Verify output from vendor AI research tools the same way as any other source. Counsel attributed the errors to a "trusted legal vendor's AI tool" and conceded she did not personally verify the citations.
- Review whether the same drafting practice was used in other matters. The court heard this attorney's explanation in a second case with the same issue and applied it here.
