Panaji, April 23: It was improper for Rajya Sabha Chairman M. Venkaiah Naidu to make advance publicity a ground to reject an impeachment motion against CJI Dipak Misra since many BJP leaders have done so in the past, Goa Congress President Shantaram Naik said on Monday. “A number of leaders of the BJP, when they were in the opposition, let go no opportunity to give advance publicity to their notices,” Naik said in a statement here.
