Heading the PAC, Murli Manohar Joshi clearly knew his rights and priviledges and has no intentions of calling people such as Ratan Tata, Neera Radia and Anil Ambani for interrogation. But like we say, “Chor ki daadhi mein tinka”, these three and several others wrote letters to the PAC saying they wanted to clear their stand on the whole thing. What more could have Joshi asked for – he instantly called for them, knowing well that the rights of PAC are limited to the suits filed by the CAG on the 2G scam.
