Mehli Mistry has officially resigned from his position as trustee of the Tata Trusts, concluding a period of speculation regarding his role. His resignation affects all three trusts under the Tata umbrella: the Sir Ratan Tata Trust, Sir Dorabji Tata Trust, and the Bai Hirabai J. N. Tata Navsari Charitable Institution Trust. Mistry's tenure ended on October 28, following a vote where key trustees, including Noel Tata, opposed his reappointment as a lifetime trustee.

In a letter addressed to Noel Tata, Mistry expressed his commitment to the vision of Ratan N Tata, emphasizing the importance of maintaining the integrity of the Tata Trusts. He stated, "My commitment to Mr. Ratan N Tata’s vision includes a responsibility to ensure that the Tata Trusts are not plunged into controversy. I believe that precipitating matters would cause irreparable harm to the reputation of the Tata Trusts."

Mistry urged the remaining trustees to adhere to principles of transparency and good governance, stating, "I hope that the actions of the other trustees going forward will be guided by the principles of transparency, good governance, and public interest." He concluded his letter with a quote from Ratan Tata: "Nobody is bigger than the institution it serves."

Prior to his resignation, Mistry had filed a caveat with the Maharashtra Charity Commissioner, seeking a hearing regarding any changes to the trustee list. Despite stepping down from the Tata Trusts, he will continue his involvement with the Tata Education and Development Trust and Breach Candy Hospital, where the Tata Group recently contributed Rs 500 crore from its CSR funds. Mistry's departure marks a significant shift in the governance of the Tata Trusts, which have been known for their philanthropic efforts and commitment to ethical practices.
