The Central Information Commission (CIC )) is believed to have sought reasons from CBI for not chargeheeting Ambani brothers in the call re-routing case.

Giving the order, Gandhi said, "From the facts before the commission, it appears that you have failed to comply with the order of the commission and not provided the requisite information within the time limit specified. The denial on your part in providing information amounts to willful disobedience of the commission''s order and also raises a reasonable doubt that the denial may be mala fide."
 
Last year, the CBI had filed a charge sheet against Manoj Modi and five others in a case relating to masking of international calls as local by Reliance Infocomm when it was controlled by Mukesh Ambani-led RIL.
 
RTI applicant P C Srivastava had sought to know from the CBI the reasons for not making Anil Ambani and Mukesh Ambani as accused in the case relating to alleged manipulation and tampering of calling lines identification of ISD calls by Reliance Infocomm Ltd and thereby passing off international calls as local ones.
 
The agency refused to disclose the information saying doing so would adversely affect its prosecution in the case. When the matter reached the transparency panel, the CBI told information commissioner Shailesh Gandhi that the reasons for not prosecuting the Ambanis were on record.
 
The CBI had taken up the investigation of the company in 2006, a year after Mukesh and his younger brother Anil reached a family settlement to divide the Reliance empire, as part of which the Reliance Infocomm went to Anil. The company has since been rechristened Reliance Communications.
 
Besides Modi, CBI named Akhil Gupta, Shankar Adawal, Pankaj Powar, K R Raju and Bhagwan Das Khurana of Reliance Infocomm Ltd in the charge sheet. Gupta has since left the Mukesh Ambani group and is now heading Blackstone, a leading US private equity firm.

The case relates to manipulation and tampering of calling lines identification of ISD calls by Reliance Infocomm and thereby, passing off international calls as local ones and causing loss to the government and its PSUs, BSNL and MTNL, to the tune of several crores of rupees.
