Amanda Adams v. Allen Butler Construction, Inc.

What happened

In CA Texas, USA, a filing relied on an unnamed/unconfirmed AI tool to help draft legal argument. The court identified the following problems with the citations in that filing:

Fabricated (Case Law)

Appellant cited several cases that do not exist; the court found many authorities she cited were non-existent and therefore could not support her arguments.
False Quotes (Case Law)

Appellant attributed quotations to real cases that the court found do not contain the quoted language (fictitious quotations).
Misrepresented (Case Law)

Appellant inaccurately described case holdings and mischaracterized the propositions for which authorities were cited.
Misrepresented (Exhibits & Submissions)

Appellant mischaracterized clerk's and reporter's records in her brief, according to the court's review.

Which AI tool

an unnamed/unconfirmed AI tool. Note: Charlotin's public database records tool attribution only where a court order, brief, or reporting on the matter states it explicitly; "unidentified" or "implied" means the record indicates AI use but does not name a specific product — we do not guess.

Outcome

Not specified in source record.

How Citation Safe would have caught this

Citation Safe runs three deterministic layers before a brief is filed: (1) does the citation exist against CourtListener's database of published opinions, (2) if quoted, does that exact language appear in the source, (3) does the cited case actually support the proposition it is cited for. Fabricated case citations fail Layer 1. Fabricated or misattributed quotations fail Layer 2 even when the underlying case is real. Misrepresented holdings — a real case cited for a proposition it does not support — are the target of Layer 3. None of these checks involve asking another language model whether the citation looks right; they are lookups and text-matches against the actual source, which is why a hallucinated citation has to survive a direct lookup against the authoritative source — not another model's opinion — to earn a VERIFIED stamp; our measured false-verify rate is published live at /quality.
