The apex court, which perused the confidential reports of the 10-member committee, said the scrutiny of call details of Radia with politicians, corporates and others reflect the issues concerning national security and appointments of members in Railway Board.
Observing that "the recent issue concerning the Railway Board Member" also comes to light on scrutiny of the intercepted conversations of Radia, a bench of justices G S Singhvi and V Gopal Gowda said, "actually money is paid".
"On the aspect of the security of the nation, the report is hazy but extremely serious and needs thorough scrutiny of the call details. We would not like to have it unless some substantial material is found.
"They are throwing light on different aspects. Our perception was that everything was related to spectrum etc but it is far more wide and different altogether. There is serious cloud on some of the issues," the bench observed.
