Brazilian Court Sanctions Lawyers for Prompt Injection in Court Filing

A Brazilian labor court fined two lawyers approximately $16,000 for embedding a hidden prompt-injection command in a court filing designed to manipulate the court's AI review system into providing a superficial analysis. The lawyers hid instructions in white text on a white background directing the AI to avoid challenging documents and bias its judgment in their favor. This case marks the first known global judicial ruling addressing intentional manipulation of a court's AI system and affirms that filing integrity extends to machine-readable content.
