Brazilian court sanctions lawyers over prompt injection
The gist
A Brazilian labor court fined two lawyers about $16,500 for hiding an instruction telling the court's AI to review their petition only superficially.
The ruling treats a filing's machine-readable text as part of court conduct, and a U.S. judge has already cited it.
