The Tata Trusts' public split over merging group companies into Tata Sons raises questions about the future of India's largest conglomerate. Here is what is happening.

**What is proposed?** The merger of Tata Electronics Systems Solutions and Tata Consulting Engineers into Tata Sons, the group's holding company. A letter dated September 28 backed the move.

**Why the fight?** Trustees Noel Tata and Venu Srinivasan said on September 30 that they were not consulted on the September 28 letter. This signals disagreement at the very top of the trusts.

**What is the RBI angle?** On September 11, the RBI kept Tata Sons in the NBFC-Upper Layer. This classification brings tougher rules on governance and disclosure. The group has been exploring ways to restructure.

**Why does it matter?** The trusts control Tata Sons. A split among trustees can slow or block major decisions. The Tata group rarely airs internal disagreements in public.

**What next?** Watch for a consensus among trustees. Any merger needs their backing. The RBI's regulatory stance will also shape what structures are possible.

The dispute is as much about process as substance — who decides, and how, at the top of the group.
