?Special Judge O P Saini sought the file after DoT Under Secretary S P Sharma submitted that it had gone missing and that he needed a week's time to trace it.

"S P Sharma, Under Secretary (DoT), is also present and submits that file number 9-1/2009-RESTG is not readily traceable as the same has been misplaced. He submits that he may be granted one week time either for producing the file or a reconstructed copy thereof.

"Prayer allowed. He is directed to either produce the original file or a reconstructed one within a week," the judge said.

The department, however, produced another related to the statement by a prosecution witness and former Telecom Regulatory Authority of India (TRAI) Chairman Nripendra Mishra, before the court today.

"Manish Jain, Assistant Director General (DoT), is present in the court on being summoned to produce main file number 20-73/2006-AS-I, along with two parts bearing number 20-73/2006-AS-I (Pt.) and 20-73/2006-AS-I (Pt-II). He submits that he has brought the said file. The same be retained on the court record till the examination of PW Nripendra Mishra," the court said.

The judge said if desired, the accused in the case were at liberty to inspect the file and get its copies.

The court also allowed the application of accused Vinod Goenka, promoter of Swan Telecom, for exemption from personal appearance for today on the grounds of sickness of his father.

The court, meanwhile, recorded the statement of Reliance Infrastructure Ltd's Senior Executive Vice President (Accounts and Finance) of Reliance Infrastructure Ltd Ashish Tambawala as witness in the case.

During the proceedings, Tambawala identified his signature on a March 2, 2007 payment transfer letter of Rs 100 crore from Reliance Energy Limited to Sonata Investment Limited, an alleged associate of Reliance ADA Group.

"I have been shown payment transfer letter dated March 2, 2007 of Rs 100 crore from Reliance Energy to Sonata Investment Limited...The letter has been signed by me at point 'B'. I am, however, unable to identify the signature at point 'A' on this letter," said Tambawala, whose recording of the statement remained inconclusive.

Tambawala, during the recording of his statement earlier, had identified various documents, including payment transfer letters and cheques exchanged between the alleged associate companies of Reliance ADA Group.
