It is a major win for Cyrus Mistry in his legal battle against the Tata Sons. The company appellate tribunal has restored him as the executive chairman of the Tata Group. The tribunal also held the appointment of N Chandrasekaran as executive chairman as illegal. However, NCLAT has allowed the Tata Group four weeks to appeal against the order. Remember Cyrus Mistry was removed as the Tata Sons chairman in November 2016 – Cyrus Mistry had then moved the NCLT, which was the start of a long protracted legal battle.
