Parliament Just Used Entry 54 to Undo What a 9-Judge Bench Gave States Under Entry 50

The Six Words in Entry 50 That Made This Bill Possible Entry 50 of the State

List gives states the power to tax mineral rights - but it adds a qualifier the 2026 headlines have mostly ignored: "subject to any limitations imposed by Parliament by law relating to mineral development." Those words are why the MMDR Amendment Bill, 2026 is constitutional even though it guts, in practical effect, a ruling nine Supreme Court judges delivered barely two years ago.

In July 2024, a 9-judge Constitution Bench in Mineral Area Development Authority v. Steel Authority of India held 8:1 that royalty on minerals is not a tax and that states retain genuine taxing power over mineral rights under Entry 50 - overruling the 1989 India Cements judgment that had held the opposite for thirty-five years.

Mineral-rich states like Jharkhand moved fast: Jharkhand passed its own Mineral Bearing Land Cess Act in 2024 and started collecting revenue it had been denied for decades.

Where the Constitution Actually Allows This

Parliament's response was not a constitutional amendment - it didn't need one. Entry 50 itself invites Parliament to impose limitations on state mineral taxation "by law relating to mineral development," and Entry 54 of the Union List separately gives Parliament authority over mineral regulation.

The new Section 9D, capping what states can levy, is Parliament legislating squarely inside the qualifier the Constitution's own text built into Entry 50. The 2024 judgment affirmed a state power that was always conditional; the 2026 Bill is Parliament exercising the condition.

The Question This Doesn't Answer

What it does not settle is whether Parliament's cap is a genuine exercise of "regulating mineral development" or a disguised attempt to reclaim taxing authority the Constitution Bench just confirmed belongs to states - a distinction courts have had to draw before between a regulatory measure and a revenue measure wearing regulatory clothing. Jharkhand's Rs 13,215 crore projected loss is the number that will likely anchor any legal challenge: if the cap's practical effect is indistinguishable from stripping the taxing power itself, rather than merely regulating its exercise, that is the argument mineral-rich states are expected to make in court.

Why This Is the Real Story, Not the Politics Chief

Ministers calling this "retrogressive" or a "black Bill" is politics. The constitutional question - whether Entry 50's own built-in qualifier lets Parliament functionally reverse a Constitution Bench's holding without ever touching Article 246 or the Seventh Schedule - is what will actually determine whether Section 9D survives judicial review and it is the question every aspirant should be able to answer independent of which side of the federalism debate they find persuasive.
