Clark v. CoreCivic, Inc.
U.S. District Court, Western District of Oklahoma · W.D. Okla. · Oklahoma bar guidance
Conduct
Pro se prisoner brief contained AI-generated citation errors plus an inadvertently preserved AI rewrite-prompt response in the introduction.
Consequence
Magistrate's R&R recommending summary judgment for defendant; admonishment that further mischaracterizations may draw Rule 11 sanctions.
Lesson
AI rewriting tools leave forensic fingerprints; the AI-generated 'here is a smoother version' framing is itself evidence of AI use.

Summary
Pro se federal prisoner Dewayne Clark filed a state-law negligence and civil conspiracy action against CoreCivic, Inc. arising from a prison transport accident. In response to CoreCivic's motion to dismiss for failure to exhaust administrative remedies, Plaintiff's Response (Doc. 22) and Surreply (Doc. 31) contained multiple citations the Magistrate Judge could not locate or that did not stand for the proposition cited. Specific examples included a citation to Tuckel v. Glover for language not in the opinion, a citation to Braham v. County of Washington that the Court could not locate, and a citation to Jones v. Bock for a proposition the cited opinion did not contain. The Court flagged a separate textual signal of AI use in the Response: the introduction opened with "Here is a smoother, more cohesive version in which the second paragraph naturally grows out of the first," language characteristic of an AI tool's response to a rewriting prompt, inadvertently preserved in the filed brief. After a December 22, 2025 admonishment, Plaintiff filed the Surreply representing he had reviewed all authorities for accuracy, but the Surreply itself contained additional errors.

What sanction did the court impose?
Magistrate Judge issued a Report and Recommendation recommending conversion of CoreCivic's motion to dismiss to one for summary judgment and grant of summary judgment to CoreCivic and the unserved defendants on failure-to-exhaust grounds. Plaintiff was admonished in the December 22, 2025 order that further mischaracterizations of facts or case law may result in Rule 11 sanctions; no monetary sanction imposed in the March 6 R&R, but the order quotes the Tenth Circuit's recent Dodds v. Bridges warning to pro se litigants and counsel about responsibility for the accuracy of AI-assisted citations.
Why does Clark v. CoreCivic, Inc. matter for law firms using AI?
Clark is a clean illustration of two AI-detection signals beyond the usual fictitious-citation pattern. The first signal is the inadvertently preserved AI prompt response, “Here is a smoother, more cohesive version in which the second paragraph naturally grows out of the first.” That is not a defective citation; it is a forensic artifact of a rewriting prompt that the filer failed to delete before filing. The Magistrate Judge surfaced this in a footnote as additional reason to believe AI was used. The second signal is the two-strike pattern: a December 22, 2025 admonishment for citation problems, followed by a Surreply explicitly representing that all authorities had been reviewed for accuracy, which itself contained further citation errors. The combination undermined the post-hoc certification.
For a managing partner, the practical lesson is that AI-assisted drafting now leaves multiple categories of forensic fingerprint. Courts increasingly recognize all of them. The citation problem is the most visible, but the prompt-response framing (“Here is a smoother version”) is evidentiary on its own. Firms running internal AI-use policies should add a pre-filing checklist item: scan for AI-rewrite framings in the introduction and conclusion of every filing, regardless of whether the body’s citations have been verified. The Tenth Circuit’s Dodds v. Bridges, quoted in this R&R, makes the responsibility-for-accuracy obligation a circuit-level holding that district courts will increasingly invoke as binding.
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.
- Train associates and contract attorneys to remove AI rewrite framings ("Here is a smoother version," "Here is a revised draft," "I have improved the flow") before filing. Courts treat these phrases as evidence of AI use independent of any citation problems.
- A two-strike pattern, defective citations in the original brief plus additional defective citations in a surreply that explicitly affirmed accuracy review, undermines the credibility benefit of post-hoc certification language.
- Pro se prisoner filings increasingly rely on AI; corrections and prison-conditions defendants should expect the citation-verification burden in their Rule 11 review to remain non-trivial.
- The order cites the Tenth Circuit's Dodds v. Bridges warning, signaling that the circuit-level guidance on AI-assisted citations now functions as binding district-court authority for Rule 11 inquiries.

- The R&R is signed by 'the undersigned Magistrate Judge' and Judge Scott L. Palk is the referring district judge per the order's caption. Magistrate Judge attribution to Chris Stephens follows the Ropes and Gray tracker entry; the order PDF text extraction did not capture the signature block clearly enough to confirm the magistrate judge's name from the document itself.
