Last year on December 18, Special Judge O P Saini had extended the relief granted to Chidambaram and his son Karti after the CBI and the ED submitted that new material has been recovered which needs to be collated. It also granted time till January 11 to the CBI to get sanction to prosecute some of the people accused in the case.

The CBI had on November 26 told the court that Centre had granted sanction to prosecute P Chidambaram.

Last year on July 19, the Central Bureau of Investigation (CBI) had filed a fresh charge-sheet in the Aircel-Maxis case in a Delhi Court against 18 accused, including Chidambaram, his son, Karti, and select government officials (serving and retired).

In its new charge-sheet, the CBI had said that two sets of money trails were discovered regarding the Foreign Investment Promotion Board (FIPB) clearance.

The Aircel-Maxis deal case, which emerged out of 2G spectrum cases, pertains to a grant by the Foreign Investment Promotion Board (FIPB) to firm M/S Global Communication Holding Services Ltd for investment in Aircel.

The ED had earlier said that the FIPB approval granted in 2006 by Chidambaram was beyond his mandate as he was only authorized to accord approval on project proposals up to Rs 600 crore.

Chidambaram’s son Karti was arrested on February 28, 2018 at the Chennai airport upon his return from the United Kingdom, for his alleged role in the case. Currently, Karti is on bail too.
