On April 9, 2026, Sullivan & Cromwell LLP\u2014one of Wall Street’s most prestigious law firms, whose fees easily exceed $2,000 an hour\u2014filed an emergency motion in Manhattan bankruptcy court on behalf of Interpath Advisory, the liquidator of Chen Zhi’s assets located in the British Virgin Islands (BVI). The document was riddled with legal precedents. The problem: several of them were bogus.<\/p>\n
But why did this case end up in an American court? In January 2026, the Attorney General of the British Virgin Islands (BVI) obtained a ruling from the Eastern Caribbean Supreme Court (ECSC) appointing Interpath Advisory as the provisional liquidator of 30 offshore companies linked to Chen Zhi\u2014including Simply Advanced Limited, the holding company that controls 57% of Allied Cigar Corporation, co-owner of Habanos S.A. Interpath is now seeking recognition of this BVI procedure in US courts in order to access assets and financial documents held in the United States and extend its mandate to other jurisdictions. It is this request for recognition\u2014filed on April 8, 2026, in the Manhattan Bankruptcy Court\u2014that led to the emergency motion drafted\u2014somewhat hastily\u2014with the help of an AI tool.<\/p>\n
<\/p>\n
These are \u201challucinations\u201d\u2014the established term for the fabrications of generative artificial intelligence tools, which boldly invent legal references, case numbers, and judgment conclusions that never occurred. The firm itself acknowledges this in a letter of confession addressed to Judge Martin Glenn on April 18, signed by partner Andrew Dietderich: \u201cThe inaccuracies and errors in the motion include artificial intelligence \u2018hallucinations.\u2019\u201d<\/p>\n
Sullivan & Cromwell specifies that it has \u201ccomprehensive and rigorous\u201d internal policies on the use of AI, including mandatory training for any lawyer wishing to access it, and a principle of systematic verification: \u201ctrust nothing and verify everything.\u201d The firm acknowledges, offering profuse apologies to the judge and the opposing party, that these policies were not followed in this particular case.<\/p>\n
The motion was corrected and refiled the same day. Honorable Judge Martin Glenn of the U.S. Bankruptcy Court for the Southern District of New York nevertheless granted the requested provisional protection on April 23, and the case proceeded.<\/p>\n
The interesting detail: it was Boies Schiller Flexner LLP\u2014the opposing firm, representing Cosimo Borrelli, the rival administrator appointed by Chen Zhi’s partners\u2014that alerted Sullivan & Cromwell to its own errors. Andrew Dietderich made a point of calling them personally to thank them.<\/p>\n
