Tata Trusts chairman Noel Tata conveyed to Tata Sons board after the meeting last week that several key issues remained unresolved, rendering any formal discussion on the reappointment of the holding company’s chairman N Chandrasekaran premature, said people familiar with the matter. That could lead to a deadlock between Chandra and Tata, they said. Tata sought greater clarity from Chandrasekaran on the group’s five-year strategic roadmap, the framework for providing an exit option to Shapoorji Pallonji Group that doesn’t involve Tata Sons going public as well as his formal position on the long-debated matter of the listing.
