Surat, India: a customs officer's ₹425 crore penalty order against a diamond trader relied on non-existent and misattributed case law that India's Supreme Court found 'appears to be a hallucination of AI'; the court set the order aside after the trader had lost in the Gujarat High Court
On 8 October 2025 the Additional Commissioner of Customs in Surat imposed a penalty of ₹425,27,99,100 (about ₹425 crore) on a diamond trader under Section 114 of the Customs Act, 1962, for allegedly misdeclaring a consignment of natural diamonds as lab-grown diamonds to pay a lower tariff. The trader's challenge was dismissed by the Gujarat High Court on 20 January 2026. Before the Supreme Court the trader argued that judgments and articles cited in the penalty order had been generated using artificial intelligence. On 2 September 2026 a bench of Justices Dipankar Datta and Sheel Nagu, after checking the material, found that the order relied on case law that was non-existent or carried fake citations, and on real cases that did not lay down the propositions attributed to them, which the court said 'appears to be a hallucination of AI'. Holding that the use of AI and reliance on this dubious material was fatal to the order, the court set aside both the penalty order and the High Court's order without deciding the merits, sent the matter for fresh adjudication by a different officer of the same rank, and left any action against the order's author to the appointing authority.
