New Delhi, July 24 -- The Supreme Court on Wednesday dismissed a plea filed by Kalanithi Maran and KAL Airways challenging a Delhi High Court order that had rejected their claim seeking Rs.1,323 crore in damages from SpiceJet.

Maran and KAL Airways had also paid Rs.679 crore to SpiceJet for issuing convertible warrants and preference shares. However, these were never issued under Singh's management, prompting Maran to approach the Delhi High Court in 2017 seeking a refund....
