What happened

Attorneys submitted AI-generated briefs containing non-existent legal citations in a vineyard inheritance dispute. The court dismissed the case with prejudice and sanctioned the attorneys $110,000 in fines and fees. The court noted that one attorney attempted to cover up the errors after they were flagged by opposing counsel.

What broke inside the model

Failure path · mode profile · Hallucination
  1. 01 · TriggerA user asks for a fact, a citation, or a figure.
  2. 02 · Model stepThe model writes a fluent, confident answer.
  3. 03 · Control gapNothing ties the claim back to a real source.
  4. 04 · FailureA fabricated fact ships as if it were verified.
  5. 05 · ConsequenceThe false claim reaches a customer, a court, or the public.

Confidence holds, and even spikes, as the claim detaches from any source.

The generative AI tool produced fictional legal citations and case law that were not verified by the attorneys before submission. The failure was compounded by insufficient human oversight and a term to amend filings without correcting the hallucinations.

How Realm would have caught this

Controls for this failure mode
  • Prism
  • OmniGuard
  • AI Detection & Response (AIDR)

A runtime layer that watches the model's internal state can flag the moment a model commits to a claim it has no support for, and hold or reroute the response before it reaches a user. Realm reads those signals in real time rather than grading the transcript after the fact.
