What was hallucinated

Fabricated: Case Law | "Awatere Huata v Prebble [2002] 3 NZLR 827" — example of a real case name paired with an incorrect citation; Court found it to be a hallucinated/erroneous citation. || Misrepresented: Case Law | "Baird v R [2013] NZSC 120" — cited in submissions with an incorrect citation; Court identified this as an example of AI-produced incorrect authority. || Misrepresented: Case Law | "Teddy v Police [2015] NZSC 62" — real case name combined with an incorrect citation; Court treated it as an AI-generated hallucinated authority and noted the genuine case/citation combination was not directly relevant.

Jones v. Family Court at Whangarei

What happened

In Supreme Court, New Zealand, 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)
    "Awatere Huata v Prebble [2002] 3 NZLR 827" — example of a real case name paired with an incorrect citation; Court found it to be a hallucinated/erroneous citation.
  • Misrepresented (Case Law)
    "Baird v R [2013] NZSC 120" — cited in submissions with an incorrect citation; Court identified this as an example of AI-produced incorrect authority.
  • Misrepresented (Case Law)
    "Teddy v Police [2015] NZSC 62" — real case name combined with an incorrect citation; Court treated it as an AI-generated hallucinated authority and noted the genuine case/citation combination was not directly relevant.

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.

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.
