D'Angelo v. Vaught
CC Illinois · Apr 2, 2025
What happened in this matter?
The court imposed a $2,000 monetary sanction against attorney Scott Walker for twice citing a non-existent case in court filings. The attorney attributed the error to the use of Smokeball's AI tool, Archie, which he claimed inadvertently altered or replaced his intended citations during the document editing process.
- Why the court cared
- The court reasoned that under Illinois Supreme Court Rule 137, an attorney's signature certifies that a filing is well-grounded in fact and law. The court determined that the attorney's failure to verify the existence of cited cases, whether due to negligence or reliance on AI, warranted a sanction to deter future frivolous filings and uphold the integrity of the court's proceedings.
- Why it matters now
- Vendor-branded legal AI tools like Smokeball's Archie still hallucinate; treat every output as unverified until cite-checked.
Why this matter is tracked
In D'Angelo v. Vaught, the Circuit Court of the First Judicial Circuit of Illinois sanctioned attorney Scott Walker $2,000 for citing a non-existent case, Hauter v. DeWitt, in two separate court filings. The attorney admitted to using Archie, an AI tool developed by Smokeball, to edit his drafts, which resulted in the insertion of the fabricated citation. The court found that regardless of whether the error was intentional or negligent, the attorney failed to fulfill his duty under Illinois Supreme Court Rule 137 to ensure that filings are well-grounded in fact and law. The court emphasized that counsel must thoroughly review AI-generated content and understand the limitations of the tools they employ before submitting work to the court.
