US District Judge Nicholas Garaufis on Monday approved the Justice Department’s request to dismiss the charges against Mr Adani and his companies. Mr Adani and his companies have consistently denied the allegations. The criminal case is separate from other legal proceedings involving Mr Adani and his companies in the US. Mr Adani, 64, is chairman of the Adani Group, a major Indian conglomerate with interests spanning energy, ports, airports and other infrastructure.
