What happened
Rafael Ramirez, representing HoosierVac LLC, filed three briefs in the Southern District of Indiana containing fabricated citations generated by a generative AI tool. When the court could not locate the cited authorities, Ramirez admitted he relied on AI to draft the briefs and did not verify the outputs. Judge Hanlon ultimately sanctioned Ramirez personally $6,000, reducing the magistrate's previous $15,000 recommendation and referring him for further disciplinary action.
What broke inside the model
- 01 · TriggerA user asks for a fact, a citation, or a figure.
- 02 · Model stepThe model writes a fluent, confident answer.
- 03 · Control gapNothing ties the claim back to a real source.
- 04 · FailureA fabricated fact ships as if it were verified.
- 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 mechanism was the attorney using a generative AI tool for legal research that produced plausible but fictitious case citations, followed by a lack of independent verification of those authorities before filing. This breakdown in due diligence exposed the court to non-existent authorities and sanctions.

How Realm would have caught this
- 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.
