The Supreme Court on Monday asked Chitra Ramkrishna, the former managing director and chief executive officer of the National Stock Exchange of India (NSE), to deposit half of the ₹25 lakh penalty amount that was confirmed by the Securities Appellate Tribunal (SAT) in the dark fibre and leased line connectivity case. A bench led by Justice Sanjiv Khanna while issuing notice to Sebi said there will be a stay on any coercive steps to recover the penalty amount.
