In a first, the Supreme Court today ordered a warrant against High Court Judge CS Karnan for skipping a contempt case hearing, to be served "personally" by the Bengal police chief. In another unprecedented move, Justice Karnan called a "court" on the lawns of his home in Kolkata and ordered the CBI to investigate the seven Supreme Court judges who issued a contempt notice against him. "The Supreme Court is not my master," said the judge, alleging that he was being targeted because he is a Dalit.
