When a Judge Used AI and the Supreme Court Took Notice | AI Hallucination Legal Case

India’s Supreme Court and Andhra Pradesh High Court became early AI law landmarks when advocates submitted fake judgments generated by artificial intelligence.

Both decisions send a clear warning: Indian courts will not tolerate AI-generated misinformation.
