A litigant in Kansas attempted to embed hidden instructions in court documents—a technique called prompt injection—betting that a judge using AI tools to review filings would execute those commands instead of reading the actual legal argument. The gambit failed immediately because the judge was reading manually, but it exposes a real vulnerability: as courts adopt AI to manage document review and legal research, adversaries will exploit that automation layer with techniques designed to hijack the AI's outputs rather than persuade the human decision-maker. Courts will need to establish explicit protocols around AI use in adjudication before this becomes a common tactic.
