New Delhi: The Tata Trusts has challenged the validity of Tata Sons' September 17 decision to reappoint N Chandrasekaran as chairman, arguing that the company's Articles of Association require affirmative support from a majority of its Trust-nominated directors and that a chairman's casting vote cannot override that condition.

The dispute at Tata Sons escalated last week after the group's biggest shareholder called the board's decision to reappoint executive chairman N Chandrasekaran illegal. Noel Tata, who chairs the network of charitable trusts holding roughly two-thirds of Tata Sons' shares, cast the sole vote against extending Chandrasekaran's tenure by five years. Venu Srinivasan, the other Tata Trusts nominee on the Tata Sons board, supported the extension.

In a statement, the Trusts said there was no deadlock at the board meeting and that the resolution could not have been validly passed after one of the two Trust-nominated directors voted against it.

"There are two Tata Trusts nominees on the Board of Tata Sons. Majority amongst two is two and not one," the Trusts said. "On September 17, 2026, one such Director voted against the resolution. Thus, the affirmative support of Tata Trusts Nominee Directors as mandated by the AoA was not given. The condition failed, and so did the resolution."

Tata Sons' board had voted 4-1 in favour of giving Chandrasekaran another five-year term as executive chairman, with Tata Trusts Chairman Noel Tata opposing the proposal. Chandrasekaran, who had earlier said he would not seek another term, agreed to continue after the board asked him to reconsider.

The Trusts, which collectively hold about 66 per cent of Tata Sons, said the overall board tally was irrelevant because the Articles impose a separate requirement relating to Trust-nominated directors.

"Whether the result of the vote was 4:1, or any other figure, is irrelevant. A condition is either met, or it is not. In this case the condition was not met," the Trusts said.

The Trusts rejected the argument that Noel Tata's opposition created a deadlock that could be resolved through the chairman's casting vote.

"The Chairman's casting vote is available only where there is equality of votes at the overall board level. It does not apply amongst Tata Trusts' Nominee Directors," it said. "There was no paralysis, and there was no deadlock. The Board put a question, and the AoA answered it in the negative. The exercise of a protective right conferred by a company's own constitution is not a deadlock; it is that constitution working as it was written to work."

The Trusts consequently said the September 17 resolution "was not validly passed and has no legal effect" and was "void ab initio" - legally void from the outset.

Tata Sons has proceeded on the basis that the board had validly approved Chandrasekaran's reappointment.

The Trusts also sought to bolster its position by pointing to Tata Sons' defence of the same Articles during the litigation surrounding the removal of former chairman Cyrus Mistry.

The Trusts said Tata Sons had previously defended the affirmative voting rights of Trust-nominated directors under Articles 104B and 121 before the Supreme Court, arguing that the provisions were legitimate protections for the company's majority shareholder.

"The Company cannot now disown the protection it went to the Supreme Court to preserve. They are either in the Articles, or they are not. Tata Sons has already told the highest court in the country that they are," the Trusts said.

The Supreme Court in the Mistry case had examined the special rights contained in Tata Sons' Articles, including provisions concerning Trust-nominated directors. The current dispute, however, concerns the interpretation and application of those provisions to the September 17 reappointment resolution.

The boardroom dispute comes amid a broader disagreement over Tata Sons' future structure.

Tata Sons' board on September 17 also approved steps towards a potential listing of the holding company after the Reserve Bank of India rejected its application to surrender its registration as a core investment company. The Trusts has opposed listing and urged the company to explore alternatives.

The Trusts had earlier said Chandrasekaran's August 12 decision not to seek another term had been accepted by it and that a successor-selection process should begin under the Articles. The Trusts maintains that Chandrasekaran's subsequent reappointment was inconsistent with that earlier process.

The latest dispute also comes ahead of Tata Sons' pending shareholder meeting. Chandrasekaran's continuation as a director is a separate shareholder matter from the board-level decision on his chairmanship.

The Trusts concluded by framing the dispute as one over the preservation of their role in Tata Sons and the wider Tata Group, saying the issue was not simply "which framework governs Tata Sons better or who governs Tata Sons better" but "who is left in the room to speak for the millions of underserved and excluded Indians" who have been at the centre of the Trusts' philanthropic work.

On arguments that listing would improve governance, the Trusts said that amounted to "pulling apart a hundred-year-old structure to fill an imaginary gap is taking a sledgehammer to crack a nut."

"It is also suggested that listing is to be welcomed because it will bring enhanced corporate governance. That argument assumes a governance gap which does not exist. Independently of listing, Tata Sons has for years chosen to hold itself to the standards of a public company. Its own AoA contain provisions applicable to public companies, including the appointment of independent directors, the constitution of an audit committee and a nomination and remuneration committee, provisions governing related party transactions and the retirement of directors by rotation, together with a code of conduct for the prevention of insider trading," the statement said.

A company that adopted these standards by choice is not a company in need of the discipline that listing is said to supply, it added.
