The ED had filed the first chargesheet in the case against Chidambaram's son Karti; later, a supplementary chargesheet was also filed against him.
The ED said that Chidambaram has remained evasive and therefore grant of pre-arrest bail at this stage would be highly detrimental to the investigation.
The court extended the interim protection granted to Chidambaram and his son, Karti, till December 18.
