What business does he have to do that? This needs investigation," party's Goa leader Shantaram Naik said at a press conference at the state party Congress headquarters here.In an impromptu press conference, four senior judges of the apex court had alleged administrative malpractices in the Supreme Court allegedly at the behest of the Chief Justice of India Dipak Misra, soon after which Mishra had met the CJI.
