Tata Trusts announced on Sunday that the September 17 board resolution to reappoint N Chandrasekaran as Chairman of Tata Sons was invalidly passed.
The Trusts stated that the decision lacked the mandatory affirmative support of a majority of Tata Trusts' nominee directors as required by the company's Articles of Association.
Tata Trusts rejected the argument that listing Tata Sons is necessary for governance, noting that robust standards are already voluntarily maintained.
