Brazilian Courts Punish AI Manipulation Before the Law Defines It

Brazil's judiciary sanctioned lawyers for AI abuse before its legislature defined the rules — establishing enforcement precedent that written law has not yet caught up to.

  • ·Brazil's judiciary sanctioned AI manipulation at both first-instance and supreme court levels before any statutory definition of AI misuse in legal practice existed.
  • ·Hiding an adversarial prompt inside a petition is legally distinct from submitting hallucinated citations — courts are already treating it as an attack on adjudicative infrastructure, not a negligence failure.
  • ·The STJ's notification to the OAB signals that individual sanctions are no longer sufficient — the courts are demanding a professional standard from the bar association itself.
