Brazilian labor court fines two lawyers over hidden AI prompt injection in filing
Overview
A Brazilian labor court fined two lawyers 10% of the claim value, about $16,000, after their filing contained white-on-white text instructing the court's AI to process it superficially and ignore other instructions.
The text became visible only when its colour was changed. The court said the hidden injection damaged judicial dignity, even though the plaintiff won by default and the attempt did not affect the outcome. The lawyers were also reported to the state bar association and the regional labor court's internal oversight unit.
