Mumbai: Tata Sons chairman N Chandrasekaran's seat on the board of the Tata group holding company is set to come up for renewal at the company's annual general meeting on August 18 that's expected to draw close attention amid continuing tensions among the conglomerate's key stakeholders.Chandrasekaran, who joined the board of Tata Sons in October 2016 before being elevated as chairman in January 2017, requires reappointment as director to remain at the helm, as his chairmanship is legally contingent on retaining the board position.Also Read | Tata Sons' chairman N Chandrasekaran declines pay hike amid group concernsTata Sons declined to comment.The upcoming AGM will focus on adoption of accounts, chairman's salary and the renomination of directors by rotation. Renominations have traditionally been a routine matter but could potentially become contentious given the changing dynamics among stakeholders. None of the renominations have been challenged so far, except by SP Group in 2022.Legal restrictionsThat was when Vijay Singh was being reappointed as a nominee on the Tata Sons board. However, it went through as a majority of stakeholders voted in favour.The development assumes significance because the Sir Dorabji Tata Trust (SDTT) will be the only principal Tata Trust eligible to vote at the AGM following legal restrictions currently in place on the Sir Ratan Tata Trust after action initiated by the Maharashtra charity commissioner. While SDTT holds nearly 27% of Tata Sons, people familiar with the structure said decisions on critical matters would still require broader alignment among trustees.Also Read | No change in Tata Trustees’ support for N ChandrasekaranChandrasekaran was granted a second five-year term in February 2022. He was inducted onto the board of Tata Sons on October 25, 2016, along with Ralph Speth, then chief executive of JLR, shortly after the ouster of Cyrus Mistry. Chandrasekaran was then serving as CEO of TCS. The late Ratan Tata had then stepped in as interim chairman and led the selection process that culminated in Chandrasekaran being formally appointed executive chairman of Tata Sons on January 12, 2017.Although Tata Trusts, led by Noel Tata, had passed a resolution in July 2025 supporting Chandrasekaran’s reappointment for a third executive term, Tata has since expressed reservations over the move. Typically, such reappointments have been formalised close to the end of tenure.The issue had surfaced prominently during a February 24 Tata Sons board meeting, at which directors reportedly differed with Noel Tata over Chandrasekaran’s continuation. The majority were said to have favoured putting his third term to a vote, while Noel Tata pushed for a deferment until June, citing concerns over losses at Air India and newer ventures such as BigBasket.The reappointment was not discussed at the last Tata Sons board meeting too in June.
