Amid allegations that the manner in which the Tatas' break - up with DoCoMo was handled by Cyrus Mistry was among the reasons that led to his ouster as Tata Sons chairman, his office on Tuesday said that all decisions were in concurrence with Ratan Tata and the board.
"To begin with, the agreement with DoCoMo had been executed before Mistry became executive chairman of the Tata Group, " said an eight - point statement from the office of Cyrus Mistry.
"Insinuations that DoCoMo issue was handled under the watch of Mistry in a manner inconsistent with Tata culture and values are baseless.
Suggestion that Ratan Tata and trustees would not have approved of the manner in which the litigation was conducted is contrary to what transpired. "
This was in reference to the $1. 17 billion compensation sought by DoCoMo for breach of contract.
The statement went on to add that the Tatas requested DoCoMo to join them in seeking the approval of the Reserve Bank of India, but the Japanese entity did not agree.
While Tatas applied for RBI approval, DoCoMo initiated arbitration since such a nod was not forthcoming.
"The award was passed in favour of DoCoMo and against the Tatas.
The Tatas under Mistry did not challenge the award in the UK.
On the contrary, RBI was approached once again by the Tatas for permission to pay the amount awarded.
RBI again refused permission, " the statement said.
Tatas also deposited Rs. 8, 000 crore in Delhi High Court where DoCoMo sought enforcement of the award.
"Throughout the above process, Ratan Tata and N. A. Soonawala, Trustee, were kept informed and they participated in separate meetings held with Mistry, " said the statement, seeking to clearly state that the top management was kept in the loop.
"They also participated in the meeting with the legal counsel (a trustee of Dorabji Tata Trust who represented Tatas in the litigation).
At all times Ratan Tata and Soonawala concurred and approved the course of action adopted by Tatas and as advised by legal counsel, " it said.
"All decisions were taken with the unanimous approval of the Tata Sons Board.
In fact, all decisions were collective decisions and the actions were consistent with every such collective decision, " it added.
"In light of the above facts, to suggest that Mr. Mistry acted on his own, or contrary to 'Tata values' or without the knowledge and/or concurrence of Ratan Tata and Soonawala is as false as it is mischievous. "
Japan's NTT DoCoMo had acquired 26. 5 per cent equity in Tata Teleservices for approximately $2. 5 billion in March 2009.
In July 2014, DoCoMo told Tata Sons it was opting out.
As per the terms of the deal, it wanted the higher of either half the amount invested or fair market price.
But in February 2015, the Reserve Bank turned down Tata's request to compensate DoCoMo, after which the Japanese company moved the London Court of International Arbitration.
The court directed the Tatas to pay DoCoMo $1. 17 billion in compensation.
The payment was not made, Tatas deposited $1. 17 billion in a Delhi court, awaiting directions.
Tata Sons removed Mistry, 48, as chairman of Tata Sons last month saying he lost the confidence of the board due to several factors and that the trustees were increasingly concerned with the growing trust deficit.
Ratan Tata, who had made room for Mistry four years ago was reinstated as the chair in an interim capacity.
