After Cyrus Mistry was sacked as Chairman of Tata Sons, both parties gave out strong statements against each other with accusations financial irresponsibility and ethical impropriety. Mistry had alleged his exit as illegal, based on invalid grounds including non-performance. According to media reports, Mistry also alleged Ratan Tata's constant interference.
However, on 1 November, Ratan Tata said that the move was "a well-considered but difficult decision made after careful, thoughtful deliberations."
Tata, 78, in his latest letter to his employees, said, "The decision to change the leadership of Tata Sons was a well-considered and serious one for its board members. This difficult decision, made after careful and thoughtful deliberation, is one the board believes was absolutely necessary for the future success of the Tata Group."
Mistry was chosen as Tata's successor in November 2011 and was appointed Deputy Chairman of Tata Sons, whose board he had entered in 2006. He was made chairman on the basis of his representation from Shapoorji Palonji, the largest shareholder in Tata Sons.
