New Delhi, April 23: Attacking the rejection of the impeachment motion against Chief Justice Dipak Misra as “illegal, wrong and unconstitutional”, Congress leader Kapil Sibal on Monday said the opposition members who had signed the motion will move the Supreme Court challenging the decision of Rajya Sabha Chairman M. Venkaiah Naidu. After Naidu came out with a 10-page order rejecting the notice of motion signed by 64 MPs, he said it was unprecedented that the motion has been rejected even before it was admitted. Sibal also hoped that the Chief Justice would keep out of hearing the challenge petition. “We will certainly move the petition in the Supreme Court to challenge this order. We are confident that when we move the Supreme Court, he has nothing to do with it so that it is heard and the serious issues which are constitutional in nature in which we determine whether we will bring transparency to the process of law will be decided by the court.”
