An expert witness testifying in a lawsuit about liability
for a Houston explosion that killed three people and destroyed roughly 200 homes
used ChatGPT to write significant portions of his “expert report.”
The man, who was hired by the industrial product conglomerate 3M, exposed his AI prompts publicly.
They showed that he asked ChatGPT to help him “create an exceptional expert witness report defending the standard of care at 3M,”
and that the report should “show how 3M is 0% at fault for the explosion at Watson Grinding.”
Court transcripts, deposition documents, and discovery records shared with 404 Media show extensive AI use in an extremely high profile case, where multiple people died and hundreds of millions of dollars in total liability are at stake in ongoing litigation about the explosion.
The case also shows that the specific prompts used to create this type of expert testimony can be discoverable during a case, and that those prompts can be quite embarrassing
