New Delhi, Jan 21 (Agencies): Telecom Minister Kapil Sibal on Friday came in for severe criticism by the Supreme Court and a Parliamentary Committee  for his press statements on CAG) report on 2G scam, with both questioning whether his comments.

Responding to criticism, Sibal said "canards" had to be replied to but maintained he meant no disrespect to any institution.

The Supreme Court, while hearing the 2G spectrum case, rapped Sibal for undermining the CAG report.

"It is unfortunate. The minister should behave with some sense of responsibility," a bench comprising Justices G S Singhvi and A K Ganguly said.

"In our opinion, the CBI which is conducting investigation into the 2G scam is expected to carry out the probe without being influenced by the statement made by anybody, anywhere, including the press," the bench said.

Chairman of Parliament's Public Accounts Committee (PAC) Murli Manohar Joshi also took strong objection to Sibal's remarks against the CAG report and requested Lok Sabha  Speaker Meira Kumar to take "prompt" and "effective" steps to stop such "constitutional impropriety" by ministers.

Sibal had rubbished the CAG findings in 2G spectrum allocation that the loss to the exchequer was to the tune of Rs 1.76 lakh crore, saying these were "utterly erroneous".

Joshi questioned whether it was appropriate for Sibal who is holding the charge of the ministry concerned, to cast aspersions on CAG report after it was tabled in Parliament.

In the letter to Kumar, Joshi asked whether Sibal had expressed "such views of far-reaching implications and consequences with the knowledge and permission" of Prime
Minister Manmohan Singh.

"The statement (by Sibal) raises several issues regarding parliamentary propriety and preserving and respecting the independence of the CAG - an institution established by the Constitution - and the PAC, a Committee elected by the Parliament...," he said.

Reacting to the attack, Sibal said, "I wish to clarify that the kind of canards that was being spread on the basis of that (CAG) report needed to be responded to and there was no
avenue left to the government."

"I have always, however, also believed that there are times when we need to state, what we believe, is the truth. It is in that spirit that I have placed the fact before the public domain and I hope that no institution or authority believes that I did it with any motive or malafide intent," he said.

At the same time, he welcomed SC's "order that no MP or any other person should comment or indulge in respect of commenting on the ongoing investigation" into 2G.
