Tata Trusts and Tata Sons are locked in a governance battle over who controls India's largest conglomerate.
The Tata Sons board voted 4-1 to reappoint N. Chandrasekaran as chairman, but Noel Tata called the decision "illegal."
The dispute now moves to the Annual General Meeting, where Tata Trusts' 66% stake could determine Chandrasekaran's fate.
