MUMBAI: Cyrus Mistry said his battle against his ouster as Chairman from Tata Sons and various group companies was a matter of principle and he urged TCS shareholders to vote their conscience.In a letter sent to the shareholders of Tata Consultancy Services , barely an hour before the company was due to hold an extraordinary general body meeting to remove as director, Mistry said the future of TCS hinged on good performance and ethical practices.His removal of director is a foregone conclusion as Tata Sons owns more than 70% of the largest Indian IT company.“Whatever be the decibel level of the voice that will drown your vote, I call on you to vote with your conscience and send a signal that catalyses a larger discussion on governance reform, to save the very fabric of what we have all inherited – the Tata Values that our founders handed us,” Cyrus Mistry said in the letter.TCS is kicking of the slew of EGMs that have been called by six out of seven listed Tata Companies that have Mistry on their boards.Mistry's letter to shareholdersRe: Extraordinary General Meeting under Section 169 of the Companies Act, 2016Dear Sirs,I refer to the captioned subject. Since the requisitionist’s stake in the equity share capital of the Company is over 73%, the outcome in this particular meeting is a foregone conclusion.Yet, it is necessary for me to address this letter to you. Over the past several weeks, many have tried to mischaracterize my refusal to go without resistance, as a measure of:(a) retribution for how I was treated at Tata Sons;(b) a fight for control over operating companies; or(c) a hankering for office – a desire to reclaim a position.None of the above is true. The fight is a matter of principle rather than facing the foregone outcome. The very future of TCS hinges on good governance and ethical practices. That can flow only from the promoter and needs to permeate into the Board and Management. In the past several weeks, we have seen good governance being thrown to the wind in every sense of the term, replaced by whims, fancies and personal agenda. We have witnessed an unmatched erosion of ethical values and the very foundation of the institution being put to grave risk by the conduct of a few.What I am fighting for is to save the soul of the Tata Group . Whatever be the decibel level of the voice that would drown your vote, I call on you to vote with your conscience and send a signal that catalyses a larger discussion on governance reform, to save the very fabric of what we have all inherited -- the Tata Values that our Founders handed us.Yours sincerely,Cyrus P Mistry
