"We will not oppose it in Parliament. There is no need to take an extreme step," Pawar said, reflecting divisions in the UPA over the issue.
Congress has raised objections to the government's move to amend the Telecom Regulatory Authority of India act, saying it was done in "unholy haste".
"It is not as if a person has left government service and joined Reliance or another private sector. He has returned to the government sector," Pawar told reporters here.
Igoring objections by political parties, government yesterday introduced the Bill in the Lok Sabha to replace an ordinance issued on May 28 to change a clause in the TRAI Act which would have prevented Misra from taking up the government post after retirement.
Misra, a 1967 batch IAS officer of Uttar Pradesh cadre who retired in 2009, joined the PMO the same day the ordinance was promulgated and the bill has been brought to give his appointment the requisite legal backing.
