Details

AI UseThe plaintiff's attorneys used ChatGPT to generate case law supporting the proposition that a body corporate can be sued for defamation. They forwarded eight cases—none of which exist—to opposing counsel during a post-hearing exchange and were unable to produce them later. Counsel admitted in open court that ChatGPT had been the source.Hallucination DetailsFictitious cases included:Body Corporate of the Brampton Court v Weenen [2012] ZAGPJHC 133Body Corporate of Bela Vista v C & C Group Properties CC [2009] ZAGPPHC 54Dolphin Whisper Trading 21 (Pty) Ltd v The Body Corporate of La Mer [2015] ZAKZPHC 23Bingham v City View Shopping Centre Body Corporate [2013] ZAGPJHC 77Body Corporate of Pinewood Park v Behrens [2013] ZASCA 89Body Corporate of Empire Gardens v Sithole [2017] ZAGPJHC 23Body Corporate of the Island Club v Cosy Creations CC [2016] ZAWCHC 182Body Corporate of Fisherman’s Cove v Van Rooyen [2013] ZAGPHC 43The court verified that the citations, parties, and contents were entirely fictitious.Ruling/SanctionThe plaintiff’s entire claim was dismissed on legal grounds unrelated to the hallucinations (a body corporate cannot be sued for defamation under South African law).Punitive costs were imposed on the attorney-and-client scale for the period between March 28 and May 22, 2023, during which the plaintiff’s legal team insisted such authorities existed. The court awarded 60% of standard costs to the defendants for the rest of the proceedings. No personal sanction or bar referral was issued due to counsel’s candor and the court's confidence that the error stemmed from “overzealous and careless” use of ChatGPT, not intent to misleadKey Judicial ReasoningThe court stressed that AI tools like ChatGPT cannot be trusted for legal citation without human verification. Submitting hallucinated cases—even indirectly—misleads opposing counsel, wastes court time, and undermines trust in legal process. The incident was used to underscore that “good old-fashioned independent reading” remains essential in legal practice.

Which AI tool

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.
