Analyse the interplay between judicial pronouncements (e.g., MADA vs SAIL, 2024) and subsequent legislative amendments in shaping Centre-State fiscal relations over minerals.

Article 246 read with the Seventh Schedule places "taxes on mineral rights" in the State List (Entry 50), but expressly subjects it to limitations imposed by Parliament under Entry 54 of the Union List. This conditional grant makes mineral taxation a recurring site of judicial-legislative contestation, as the sequence from MADA v SAIL (2024) to the MMDR (Amendment) Act, 2026 shows.

Judicial phase: widening state fiscal space

• A nine-judge bench in Mineral Area Development Authority v. Steel Authority of India (25 July 2024) held that royalty is not a tax, and that the power to tax mineral rights vests in State legislatures — overruling India Cement (1990) [1].
• A follow-up order (14 August 2024) declined purely prospective operation, allowing States to recover past dues in staggered instalments [2].
• The ruling handed mineral-rich States an independent, judicially secured revenue lever.

Legislative phase: reoccupying the field

• The MMDR (Amendment) Bill, 2026, passed by Parliament on 13 August 2026, bars a State from imposing any tax, cess or levy on mineral rights or mineral-bearing lands except as the Centre prescribes [3][4].
• It operates retrospectively: unpaid past State levies are deemed invalid, though amounts already collected are not refundable [3].
• The Centre's stated rationale is fiscal certainty and predictability to attract mining investment, noting that about 90% of mining taxes and statutory payments continue to accrue to States [4].

The interplay

• This is not defiance of the Court but a legislative override — Parliament exercising the very limitation the judgment itself recognised, removing the statutory basis rather than negating the verdict.
• Consequently, States' remedy migrates from the courtroom to political channels: the BJD's Bhubaneswar protest and memorandum to the President through the Governor illustrate this shift [5].

The episode shows judicially won fiscal autonomy remaining contingent on Parliament's forbearance. A durable settlement lies in institutionalising consultation — routing such fiscal questions through the Inter-State Council and GST Council-style bargaining before enactment, so that uniformity for investors and States' constitutional revenue rights are reconciled cooperatively rather than sequentially litigated.
