What was hallucinated

False Quotes: Case Law | Plaintiff attributed a fabricated quotation to Penhallow v. Doane's Administrators, asserting governments are "abstractions" that cannot interact with "the tangible"; the Court identified the quote as fake and not in the 1795 prize case.

Details

The court found the plaintiff's objections and central claims rooted in sovereign-citizen ideology and noted a fabricated quotation attributed to Penhallow v. Doane's Administrators, 3 U.S. 54 (1795). The R&R was adopted and the action dismissed as frivolous.

Kamps v. British Crown Corporation, et al.

What happened

In W.D. Michigan, 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:

  • False Quotes (Case Law)
    Plaintiff attributed a fabricated quotation to Penhallow v. Doane's Administrators, asserting governments are "abstractions" that cannot interact with "the tangible"; the Court identified the quote as fake and not in the 1795 prize case.

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

Case dismissed as frivolous.

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.
