Charge sheet was filed before Special CBI Judge Gurdeep Singh who directed the probe agency to file all relevant documents by October 12.
"Investigating officer seeks some time to file documents, as they are voluminous. Put up for filing of documents on October 12," the court said.
The court had in September last year granted bail to all the accused, including Jain and Singal, after the CBI failed to file the charge sheet against them within the stipulated period of 60 days.
CBI had registered two separate graft cases under the Prevention of Corruption Act and the IPC for the offence of criminal conspiracy.
In August last year, CBI had arrested some of the accused in connection with the case and claimed to have recovered Rs 21 lakh in cash from Jain's residence besides gold worth Rs 1.68 crore and fixed deposit documents of up to Rs 63 lakh.
The agency has filed two cases against Jain, accusing him of receiving a bribe of Rs 50 lakh through conduits and abusing his official position to enhance the credit limits of some companies in violation of laid-down procedures.
