New Delhi, Aug. 26 -- The Supreme Court on Tuesday sought a response from Lok Sabha Speaker Om Birla on a petition filed by Trinamool Congress general secretary and parliamentarian Abhishek Banerjee seeking an expeditious decision on disqualification petitions against 20 TMC MPs who joined the Nationalist Citizens Party of India . A bench comprising Chief Justice of India Surya Kant and justices Joymalya Bagchi and V Mohana, made it clear that the issue before it was not merely whether notices had been issued to the MPs but whether the disqualification proceedings would be completed. Solicitor General Tushar Mehta, appearing for the Speaker, told the bench that there was no need to issue notice to Birla as he was appearing for him and could inform the court that notices had already been issued to the 20 MPs. "It is not a question of issuance of notices but completion of proceedings," the bench told the SG. The bench added that it was not inclined to issue notice to a constitutional authority without first giving the Speaker an opportunity to respond. "We are not inclined to issue notices to a constitutional authority without giving them an opportunity. But we want a response from the Speaker. For now, we will issue notices only to the other respondents," it said. Senior advocate Kalyan Bandopadhyay, appearing for Banerjee, asked why notice could not also be issued to the Speaker.P4...
