Making a scathing attack on the opposition led by BJP, Finance minister Pranab Mukherjee on Sunday accused them of subverting the Constitution by stalling Parliament repeatedly over the 2G spectrum issue.
He also rejected the opposition demand for a JPC probe into the alleged irregularities in the 2G spectrum allocations contending that the government had handed over the case to CBI last year "where as the BJP raised the issue only in 2010".
"You (BJP) are asking for a JPC in 2010...The CBI has been probing the 2G spectrum case since 2009. The CBI filed an FIR in the matter in October 2009," Mukherjee said while moving the political resolution at the ongoing 83rd Congress Plenary at Burari on the fringes of the national capital.
He contended that a joint parliamentary committee cannot probe any case but only make recommendation to the government.
Ruling out setting up a JPC, he said the oldest watchdog body of the country -- the Public Accounts Committee -- has been examining the 2G spectrum issue and simultaneous investigations were being carried out by the CBI, a one-man Commission set up by the Telecom Ministry, Income Tax officials and the Enforcement Directorate.
"What will a JPC do? There is no rational explanation," he said and accused the opposition of subverting the Constitution by forcing repeated adjournments of Parliamentary proceedings.
"Congress men and women will rise against any attempt to subvert the Parliamentary system," Mukherjee said.
In an oblique reference to Karnataka, he said the BJP had debarred members of a state assembly who were preparing to vote against the Chief Minister.
On the other hand, Mukherjee said Congress had changed chief ministers and cabinet ministers even if there was a "shadow of doubt against them".
