Davis v. Marion County Juvenile Detention Center
S.D. Indiana · May 20, 2026
What happened in this matter?
The court imposed a $2,000 monetary sanction on attorney Tae Sture under Federal Rule of Civil Procedure 11(b) for including two hallucinated legal citations in a court filing. The court rejected the Magistrate Judge's recommendation of a $7,500 sanction, finding that mitigating circumstances warranted a reduction.
- Why the court cared
- The court reasoned that Rule 11 requires attorneys to conduct a reasonable inquiry into the existence and accuracy of legal citations. It found that the attorney's failure to verify citations generated by Fastcase constituted a breach of this duty. The court reduced the sanction from $7,500 to $2,000 based on mitigating factors: the attorney's lack of intent to deceive, the fact that the citations supported uncontroversial legal points, the attorney's 20-year clean disciplinary record, and the compressed filing deadline.
- Why it matters now
- This case illustrates the judiciary's increasing focus on attorney accountability for AI-assisted research. It establishes that 'hallucinated' citations are a serious breach of the duty of competence and candor, regardless of whether the error was intentional or the result of reliance on legal research software.
Why this matter is tracked
The court sanctioned attorney Tae Sture for filing a brief containing two non-existent legal citations generated by the legal research tool Fastcase. The Magistrate Judge initially recommended a $7,500 sanction for violating Federal Rule of Civil Procedure 11(b). Upon review, the District Court adopted the Rule 11 analysis but reduced the monetary sanction to $2,000, citing mitigating factors including the attorney's lack of intent to deceive, the absence of a pattern of misconduct, and the attorney's 20-year unblemished record. The court emphasized that reliance on AI-generated citations reflects a concerning professional detachment and that attorneys have a non-delegable duty to verify the accuracy of all legal authorities cited in their filings, regardless of the research tools employed.
This case illustrates the judiciary's increasing focus on attorney accountability for AI-assisted research. It establishes that 'hallucinated' citations are a serious breach of the duty of competence and candor, regardless of whether the error was intentional or the result of reliance on legal research software.
