Court rules judge who used AI for ruling keeps immunity

A US federal court ruled that a judge accused of relying entirely on AI to reach a judicial decision retains judicial immunity from civil lawsuits. The ruling did not address whether such AI use is legally or ethically permissible.

Why it matters: This sets an early precedent that existing immunity doctrines shield officials even when AI use in decision-making is contested, leaving accountability questions to future legislation rather than the courts. It adds to a growing pattern, alongside the AI-hidden prompt-injection court filing story, of the justice system grappling with undisclosed or unchecked AI use in legal proceedings.
