Tushar Mehta, the Centre’s second most-senior law officer who is appearing for the investigating agency, told the top court that one key witness refused to appear for face-to-face with Chidambaram "because he is too powerful".
P Chidambaram, who is an accused in the multi-crore scams on Monday celebrated his 74th birthday within the walls of Delhi's Tihar Jail. In a series of tweets, P Chidambaram expressed his concerns over the country's economy.
The apex court had allowed Karti to travel to the United States, Spain and Germany this month and next month, asking him to deposit another Rs.10 crore as the security deposit.
On August 23, the Delhi court judge OP Saini had extended the interim protection from arrest to former Union finance minister P Chidambaram and his son Karti in the Aircel-Maxis cases for the 21st time.
Refusing to consider his plea, the court asked Karti's advocate to mention the petition before the bench headed by CJI Gogoi since there is no urgency in the matter.
On Friday, Ashok Chawla resigned as the chairman of NSE hours after the CBI informed the court that the Centre has granted sanction to prosecute him in the Aircel-Maxis case.
