"It is a matter concerning government and the cabinet to respond", party spokesman Raj Babbar told reporters.
He was asked to comment on the apex court slamming the government for not lodging FIRs on missing files and raising a question as to whether "it is an attempt to destroy the records in the case."
Holding that the missing documents are "vital" for the probe in the scam, the apex court directed the Coal Ministry to lodge complaint with CBI if it fails to trace any document sought by the agency.
