ChatGPT Chat Logs Admitted as Criminal Evidence
Chat histories many treated like personal notes have now been confirmed as subpoenable — established in a live criminal court for the first time.
What Happened
Until now, AI chat histories were rarely treated as legal evidence in criminal courts, and most users assumed conversations were as private as personal notes.
California arson case: prosecutors admitted ChatGPT chat logs into evidence. Ended in mistrial, but it's now clear AI chat histories can be subpoenaed.
Worth reviewing your history-deletion settings now. This applies to anyone using ChatGPT for sensitive work or personal matters — not just people in legal trouble.
