Expert witness caught using ChatGPT to clear 3M in $61M trial
An expert witness defending 3M in a fatal explosion trial used ChatGPT to write up to 90% of his report—and explicitly prompted the AI to show 3M was "0% at fault." Opposing lawyers uncovered 350 pages of chat logs and turned them into damning evidence, leading the jury to hand down a $61M verdict with 30% liability on 3M. Prompt histories are officially fair game in court.
