The Supreme Court was asked to value Tata Sons shares. It refused.

The Supreme Court was asked to name a price. It refused.

Written on 13 July 2026, based on public reports at that time.

In March 2021, the Supreme Court had every reason to name a number. It refused.

Tata Sons and the Shapoorji Pallonji Group had been fighting for years, and buried inside a much larger judgment was a simple commercial question. What was SP Group’s 18.37 percent stake in Tata Sons actually worth.

SP Group said about Rs. 1.75 lakh crore. Tata Sons said between Rs. 70,000 and Rs. 80,000 crore. Same shareholding, same date, a gap of over Rs. 95,000 crore.

The Court, led by then Chief Justice S A Bobde, looked at both numbers and declined to pick one. Valuation depended on listed equities, unlisted equities, immovable assets and more. The bench said plainly it could not adjudicate on fair compensation, and left the parties to resolve it through the company’s own mechanism instead.

Here is the lesson most people miss. A 250 percent gap between two competent valuers does not mean one of them is lying. It means the asset has no observable market, no last transaction, nothing a court can simply point to and adopt.

Two things follow from that.

If you are the valuer, your protection is never the number. It is whether your assumptions are documented well enough that someone can disagree with your conclusion and still see exactly how you reached it. That transparency is what survives a challenge, not a confident number with no visible reasoning behind it.

If you are the promoter or founder, the real failure happened years earlier, when nobody wrote a pre-agreed valuation mechanism into the founding documents. A formula, a pre-appointed valuer, a defined process for exactly this moment. Build it in while everyone is still on good terms. By the time you need it, it is too late to negotiate calmly.

The most expensive gap in any dispute is not between two valuations. It is the missing clause that should have decided which one wins.
