New Delhi: With Public Accounts Committee (PAC) grilling people from various sections involved in the 2G case, JPC Chairman P C Chacko raised frown saying that PAC has gone beyond its mandate.

Chacko underlined that PAC's mandate was limited to looking into accounting irregularities in 2G spectrum allocation as highlighted by the Comptroller and Auditor General (CAG) and it should not give an impression of holding a "parallel inquiry" to what JPC is supposed to do.

Chacko's comments came as the PAC, headed by BJP leader Murli Manohar Joshi, have been calling for deposition of journalists who wrote on 2G spectrum scam and editors of magazines which published the transcripts of telephonic conversations of corporate lobbyist Niira Radia with industrialists, journalists and politicians.

The PAC is also set to call for examination of Radia as also senior journalists who are in the tapes.

"Conflict should be avoided as far as possible. We will discuss it in the JPC," said Chacko, a Congress leader and Lok Sabha member from Kerala's Thrissur.

The 30-member JPC, which will have its first meeting on March 24, would be examining the work done by the PAC which has been examining the 2G issue for over a year.

The JPC will examine the telecom policy in place from 1998 to 2008, its implementation, pricing of spectrum and issuance of licences.

The aim is to ascertain if there were any problems in the system and its implementation and recommend actions accordingly.

In this connection, the committee intends to seek all relevant documents from the ministries concerned and communications between various departments.
