NEW DELHI (Reuters) - India’s top court on Friday ruled in favour of autos-to-steel conglomerate Tata Group in its long-drawn legal tussle with former chairman Cyrus Mistry whose family firm owns an 18% stake in the group holding company, Tata Sons. Mistry in 2016 was sacked from his job at the helm of Tata Sons, the holding company for the Tata Group, after he fell out with group patriarch Ratan Tata over corporate governance issues at Tata group companies. The two sides have since been embroiled in a legal battle. Reporting by Aditi Shah and Suchitra Mohanty; Editing by Sanjeev Miglani Our Standards: The Thomson Reuters Trust Principles.
