Keydata founder Stewart Ford has lost a legal battle to prevent the FSA from accessing a computer server as part of its investigation into the firm.
Ford argued the server was not relevant to the investigation into the demise of Keydata, which was placed in administration by the regulator last month.
Court documents show he tried to prevent the FSA and PricewaterhouseCoopers from accessing the server, which the regulator believes contains information on meetings the firm had with a Singapore-based businessman.
Ford says he had already offered to give the FSA any data relevant to the case, but did not agree to full access.
The Singapore business man, David Elias, who is central to the FSA's investigation, is thought to have been loaned $3.25m by Ford. His obituary appeared in the Daily Telegraph in June, but it is now known if reports of his death are true.
Ford continues to claim he is an innocent victim of an elaborate fraud devised by Elias.
