The Supreme Court has issued notice to advocate Prashant Bhushan seeking his response on why action should not be taken against him for tweeting serious allegations against the judiciary. The top court also asked Twitter India, against whom a contempt proceeding has started, why it did not remove Mr Bhushan's tweets when a contempt action became evident. The Indian arm of the microblogging website said it will convey the top court's message to its parent Twitter Inc. Last month, Mr Bhushan alleged the judiciary had a hand in dealing damage to democracy.
