It further said that Ratan Tata will be back at helm as interim chairman till the time Tata Sons find a new chairman. It said, "The Board has constituted a Selection Committee to choose a new Chairman. The Committee comprises Mr. Ratan N. Tata, Mr. Venu Srinivasan, Mr. Amit Chandra, Mr. Ronen Sen and Lord Kumar Bhattacharyya, as per the criteria in the Articles of Association of Tata Sons. The committee has been mandated to complete the selection process in four months".

Mistry, first non-Tata to be the chairman of the Group rose to the position in December 2012. 

However, Mistry's family-- Shapoorji and Pallonji Group is the second largest shareholder in Tata Sons and is unlikely to take this decision kindly. The Group termed Mistry's removal as 'illegal' as no prior notice was given. Mistry was earlier the Managing Director of Shapoorji Pallonji Group and is the youngest son Indian construction magnate Pallonji Mistry.

Let's look at shares of some of the major Tata Group companies since the time Mistry took over as chairman.
