MUMBAI, July 17 -- A special CBI court on Tuesday convicted four people, including businessman Brian Mario Castelino, his wife Rajini Castelino, their company R Tec Systems (India) Private Limited, and former Corporation Bank official Alam Mahmud Shaikh, in a Rs.6.82 crore loan fraud. The convicts were sentenced to one year of rigorous imprisonment and fined Rs.25,000. The court found that the accused gotten Rs.6.82 crore worth post-shipment credit from the Corporation Bank based on 28 falsified Softex forms (forms related to the declaration of software export), and 35 fabricated software export invoices. The court noted that wo houses in Vashi, already mortgaged with another bank, were used as fresh collateral to secure the loans. Post-shipment credit refers to payment offered by financial institutions to exporters after goods have been shipped, but before the importer has received the payment from the importer. As per regulatory procedure, the Software Technology Parks of India (STPI), an organisation under the Ministry of Electronics and Information Technology, certifies three copies of Softex forms. The original is sent to the Reserve Bank of India (RBI), and a duplicate is returned to the exporter. "The submission of original form without certification shows that fraud has been played on the Bank," the court ruled. Shaikh, who served as the Forex manager at the bank, was held complicit for approving the fake documents, the court said, adding that he had "abused his official position" and enabled the fraud. The court convicted the accused under sections of the IPC....
