MMDR Amendment Act 2026 and Section 9D — Royalty, State Levies and Fiscal Federalism: Aspirant Digest

The Mines and Minerals (Development and Regulation) Amendment Act, 2026 inserts a new Section 9D into the MMDR Act, 1957, barring State Governments in India from taxing mineral rights or mineral bearing lands except on terms the Centre prescribes. The President assented on 17 August 2026; the Act came into force 22 August 2026. It unwinds the fiscal consequences of a nine-judge Supreme Court decision.

Why this matters for aspirants. This is a first-rate federalism question, unusually well-supplied with hard facts: a dated statute, a numbered notification, a nine-judge neutral citation, an 8:1 split with a named dissent, a seven-judge decision expressly overruled, two competing entries in the Seventh Schedule, a declaration mechanism under a third, a five-day assent-to-commencement gap, and a live validating-legislation problem. A setter can build a prelims MCQ on the entry numbers, a mains essay on legislative competence, a CLAT passage on royalty versus tax, and a GS-II answer on Centre-State fiscal relations from the same material. Learn the entry numbers cold — almost every question here resolves to which entry supplies the power.

1. What the Amendment Act Actually Does

17 August 2026 | President of India / Ministry of Mines | Bill No. 154 of 2026 (Lok Sabha); recorded as Act 20 of 2026 | Exam Relevance ⭐⭐⭐⭐⭐

What happened. The Bill was introduced in the Lok Sabha on 10 August 2026 as Bill No. 154 of 2026, its Statement of Objects and Reasons signed by the Minister of Mines and dated 7 August 2026. It runs to five operative clauses, and the President assented on 17 August 2026 — an assent recorded in the President's Secretariat register of Central Bills against the Ministry of Mines.

The legal principle. The five clauses do the following:

1. Section 2 of the MMDR Act, 1957 — the declaration by which the Union takes under its control the "regulation of mines" — is widened by inserting the words "and mineral bearing lands". The declaration therefore now extends beyond mines and mineral development to the land itself.
2. Section 3 gains a new clause (ada) defining "mineral bearing land" as any land having mineral contents in accordance with the parameters prescribed under Section 5(2)(a).
3. A new Section 9D is inserted after Section 9C. Sub-section (1) bars any State tax, cess or other levy, by whatever name called, on (a) mineral rights or (b) mineral bearing lands — whether based on mineral quantity, mineral value, royalty payable "or otherwise" — except in accordance with conditions or restrictions prescribed by the Central Government.
4. Section 9D(2) carries a double non obstante clause. Notwithstanding anything in any other law "or in any judgment, decree or order of any court", any such State levy not deposited with or recovered by the State Government before commencement "shall be deemed to be invalid at all material times". A proviso protects amounts already deposited or recovered from any claim to refund.
5. Section 13(2) gains a new clause (ta), empowering the Central Government to make rules prescribing the conditions or restrictions contemplated by Section 9D(1).

For your exam. Note the asymmetry built into Section 9D(2): unrecovered demands die, recovered money stays. That is not neutral drafting — it converts the speed of a State's revenue machinery into a determinant of legal outcome. And note that until rules are notified under the new Section 13(2)(ta), Section 9D(1) admits of no prescribed exception at all, so the bar operates absolutely in the interim. A one-line examinable point: the exception exists on paper before it exists in law.

2. The Judgment It Responds To — *Mineral Area Development Authority*

25 July 2024 | Supreme Court of India, nine-Judge Bench | Mineral Area Development Authority v. Steel Authority of India, 2024 INSC 554 | Exam Relevance ⭐⭐⭐⭐⭐

What happened. A nine-judge Bench decided the case by 8:1, with Justice B.V. Nagarathna dissenting. Three holdings matter for your answer sheet:

• Royalty payable under Section 9 of the MMDR Act, 1957 is not in the nature of a tax.
• The seven-judge decision in India Cement Ltd. v. State of Tamil Nadu was overruled.
• Entry 50 of List II of the Seventh Schedule confers on State legislatures the competence to tax mineral rights.

The Court also held that Parliament cannot itself tax mineral rights under Entry 54 of List I, while acknowledging Parliament's power to impose limitations on the State entry.

The legal principle. Entry 50 is a conditional entry. It confers the power to tax mineral rights "subject to any limitations imposed by Parliament by law relating to mineral development". So the majority simultaneously restored a State taxing power and identified the constitutional lever by which Parliament could restrict it. Section 9D is Parliament pulling that lever.

The temporal order. On 14 August 2024 the same Bench addressed the ruling's temporal reach. It permitted States to recover past dues on transactions from 1 April 2005 onwards, waived interest and penalty referable to the period before 25 July 2024, and directed payment in staggered instalments over twelve years commencing 1 April 2026.

For your exam. The collision is the point. That twelve-year recovery window opened on 1 April 2026; Section 9D(2) invalidates, at all material times, every rupee of that liability which remained undeposited and unrecovered at commencement on 22 August 2026. Parliament has not merely legislated for the future — it has reached into a recovery schedule the Supreme Court itself calibrated. Memorise the two 2024 dates as a pair: 25 July 2024 (the holding) and 14 August 2024 (the temporal order). Questions frequently test the second, because most candidates only revise the first.

3. The Legislative-Competence Layer — Which Entry Supplies the Power?

Constitutional framework | Article 246 and the Seventh Schedule, Constitution of India | Exam Relevance ⭐⭐⭐⭐⭐

What happened. Article 246 read with the Seventh Schedule distributes legislative power between the Union and the States. Mining engages three entries at once, and the whole controversy is about which one is doing the work.

The legal principle. Two distinct issues arise, and they are not equally difficult.

Section 9D(1) is the easier half. Entry 50 is conditional on its face. A prospective bar on State levies on mineral rights, subject to conditions the Centre may prescribe, is a textbook exercise of a carve-out written into the entry's own text — and Mineral Area Development Authority itself acknowledged the limitation power while holding that Parliament cannot tax mineral rights under Entry 54.

The extension to "mineral bearing lands" is harder. Taxes on lands and buildings fall under Entry 49 of List II, which carries no comparable qualification. To the extent Section 9D operates on a State levy that is in substance a tax on land rather than on mineral rights, the Entry 50 carve-out does not supply the authority. The Union must instead rely on the widened Section 2 declaration under Entry 54 of List I — an entry the Supreme Court has characterised as regulatory rather than fiscal.

For your exam. This is where marks are won. The examinable proposition is that a regulatory entry cannot be stretched to do fiscal work. Frame your answer around the doctrine of pith and substance: what is the true nature of the State levy under challenge? If it is in substance a tax on mineral rights, Entry 50 and its carve-out govern and Section 9D(1) stands comfortably. If it is in substance a tax on land, Entry 49 governs, and the Union is left arguing that a declaration under a regulatory entry can extinguish a State's unqualified taxing power. State that fork explicitly; do not resolve it more confidently than the material allows.

4. Section 9D(2) — Validating Legislation and the Limits of Legislative Override

Doctrinal layer | Separation of powers | Exam Relevance ⭐⭐⭐⭐⭐

What happened. Section 9D(2) deems unrecovered State mineral levies "invalid at all material times", notwithstanding "any judgment, decree or order of any court".

The legal principle. Indian constitutional doctrine draws a line that this provision walks along. A legislature may enact validating legislation that removes the basis on which a judgment proceeded — retrospectively altering the legal foundation so that the earlier decision no longer applies to the altered law. A legislature may not declare a judicial decision ineffective by legislative fiat, because that is an exercise of judicial power and offends the separation of powers.

A provision that deems liabilities invalid notwithstanding any judgment, decree or order invites exactly the second characterisation — particularly where the liabilities were the subject of a nine-judge determination and a calibrated recovery schedule fixed by the Court itself. Whether the retroactive limb survives will depend on whether courts read it as altering the legal foundation, or as nullifying the decree.

For your exam. This is the highest-value descriptive question in the topic, and it is the one most candidates will answer badly by simply asserting an answer. Do not. State the doctrinal test, apply it both ways, and note what has not yet happened: as at 8 September 2026 no judicial decision testing the validity of Section 9D has been traced. Writing "Section 9D(2) is unconstitutional" as a flat conclusion is worse than writing "the provision engages the validating-legislation line, and the outcome turns on X" — the second shows you know the test.

5. Assent Is Not Commencement — The Five-Day Gap

22 August 2026 | Ministry of Mines | S.O. 4642(E), F. No. M.VI-11/5/2024-Mines VI | Exam Relevance ⭐⭐⭐⭐

What happened. By notification S.O. 4642(E), published in the Gazette of India Extraordinary, Part II, Section 3, sub-section (ii), issue No. 4459, Gazette identifier CG-DL-E-22082026-275676, signed by Dr. Veena Kumari Dermal, Additional Secretary, the Ministry of Mines exercised the power under Section 1(2) of the Amendment Act to appoint the date of the notification's own publication as the commencement date. The Gazette masthead reads "NEW DELHI, SATURDAY, AUGUST 22, 2026/SHRAVAN 31, 1948".

The legal principle. Three features:

• Self-referential commencement. The Act commences on the date the notification is published, not on a date recited inside it — so the Gazette masthead is itself the operative legal fact.
• Whole-Act commencement. The notification refers to "the provisions of the said Act" without qualification. No section is reserved and no differential dates are appointed.
• The default was displaced. A Central Act that appoints no commencement date comes into force on assent, under Section 5 of the General Clauses Act, 1897. Here Section 1(2) expressly required an appointed date, displacing that default. The operative date is 22 August, not 17 August.

For your exam. Resist the shorthand that an Act is "in force from assent". It is true only where the statute says so or is silent. Getting this the wrong way round shifts the boundary by five days — exactly where Section 9D(2)'s recovered/unrecovered line falls. A Saturday commencement makes no difference: commencement attaches to the appointed calendar date, not to a working day. Contrast this Act with the Prevention of Insults to National Honour (Amendment) Act, 2026, which appointed no date and so commenced on assent — together they are the cleanest available comparison pair.

Key Facts to Remember

Exam Angle

Which exams. Judiciary Mains (constitutional law paper, federalism unit); UPSC Law Optional Paper I; UPSC GS-II (Centre-State relations) and GS-III (mineral resources, revenue); CLAT and AILET legal-reasoning passages on royalty versus tax; CLAT-PG and UGC NET Law Paper II on legislative competence and the Seventh Schedule.

MCQ format. Entry numbers, the 8:1 split, the neutral citation, the two dates, and the assent-versus-commencement distinction are all single-fact items. Expect a distractor pairing Entry 50 with Entry 49, and another offering 17 August as the commencement date.

Descriptive format. Three reliable prompts: (i) "Examine the legislative competence of Section 9D of the MMDR Act, 1957 with reference to Entries 49, 50 and 54 of the Seventh Schedule." (ii) "Can Parliament by law undo the fiscal consequences of a decision of a nine-judge Bench? Discuss with reference to the doctrine of validating legislation." (iii) "Distinguish royalty from tax, and assess the significance of overruling India Cement Ltd. v. State of Tamil Nadu."

Facts to memorise. 2024 INSC 554; 25 July 2024; nine judges, 8:1, Nagarathna J. dissenting; India Cement was a seven-judge decision; 14 August 2024 temporal order (1 April 2005; twelve years from 1 April 2026); Bill No. 154 of 2026; assent 17 August 2026; commencement 22 August 2026 by S.O. 4642(E); Section 9D(1) and 9D(2); Section 13(2)(ta); Entries 23, 49, 50 (List II) and 54 (List I).

Related provisions. Articles 111, 245, 246 and the Seventh Schedule to the Constitution of India; Sections 2, 3(ada), 5(2)(a), 9, 9C, 9D and 13(2)(ta) of the Mines and Minerals (Development and Regulation) Act, 1957; Section 1(2) of the Amendment Act; Section 5 of the General Clauses Act, 1897 (as the displaced default).

Practice MCQs

Q1. In Mineral Area Development Authority v. Steel Authority of India, 2024 INSC 554, the nine-judge Bench of the Supreme Court of India held that —

(a) royalty under Section 9 of the MMDR Act, 1957 is a tax, and States cannot levy it (b) royalty is not a tax, India Cement Ltd. v. State of Tamil Nadu is overruled, and Entry 50 of List II confers State competence to tax mineral rights (c) Parliament alone may tax mineral rights under Entry 54 of List I (d) taxes on mineral rights fall under Entry 49 of List II

Answer: (b). Decided 8:1 with Justice B.V. Nagarathna dissenting. Option (c) inverts the holding — the Court held Parliament cannot itself tax mineral rights under Entry 54, which is a regulatory entry.

Q2. The Mines and Minerals (Development and Regulation) Amendment Act, 2026 came into force on —

(a) 7 August 2026, the date of the Statement of Objects and Reasons (b) 10 August 2026, the date of introduction in the Lok Sabha (c) 17 August 2026, the date of presidential assent (d) 22 August 2026, by notification S.O. 4642(E) appointing the date of its own Gazette publication

Answer: (d). Section 1(2) of the Amendment Act required an appointed date, which displaced the assent-default rule in Section 5 of the General Clauses Act, 1897. Option (c) is the trap, and it is wrong by five days — precisely the window in which Section 9D(2)'s recovered/unrecovered line operates.

Q3. Which entry of the Seventh Schedule is the hardest to reconcile with Section 9D of the MMDR Act, 1957 insofar as it bars State levies on mineral bearing lands?

(a) Entry 50 of List II — taxes on mineral rights (b) Entry 49 of List II — taxes on lands and buildings (c) Entry 54 of List I — regulation of mines and mineral development (d) Entry 23 of List II — regulation of mines and mineral development

Answer: (b). Entry 50 carries an express "subject to any limitations imposed by Parliament" qualifier, and Entries 54 and 23 are regulatory. Entry 49 carries no such qualifier, so the Entry 50 carve-out supplies no authority over a levy that is in substance a tax on land.

Q4. Section 9D(2) of the MMDR Act, 1957 provides that unrecovered State mineral levies shall be deemed invalid at all material times "notwithstanding … any judgment, decree or order of any court". The constitutional objection this attracts is that —

(a) it violates Article 14 by discriminating between mineral-bearing and other lands (b) a legislature may remove the basis of a judgment but may not declare a judicial decision ineffective by legislative fiat (c) it is a Money Bill introduced without the President's recommendation (d) retrospective taxation is per se unconstitutional in India

Answer: (b). This is the validating-legislation line, and it is a separation-of-powers objection rather than a fundamental-rights one. Note that (d) is wrong as a general proposition — retrospective fiscal legislation is not per se invalid in India.

Frequently Asked Questions

What does Section 9D of the MMDR Act, 1957 do?

Section 9D(1) bars any State Government from imposing a tax, cess or other levy, by whatever name called, on mineral rights or on mineral bearing lands — whether calculated on mineral quantity, mineral value, royalty payable "or otherwise" — except in accordance with conditions or restrictions prescribed by the Central Government. Section 9D(2) deems any such levy not deposited with or recovered by the State before commencement to be invalid at all material times, notwithstanding any other law or any judgment, decree or order of any court, while a proviso protects amounts already deposited or recovered from any claim to refund. The rule-making power to prescribe the Section 9D(1) exceptions sits in the new Section 13(2)(ta).

When did the Act receive assent, and when did it come into force?

Assent was on 17 August 2026, recorded in the President's Secretariat register of Central Bills against the Ministry of Mines. Commencement was on 22 August 2026, by notification S.O. 4642(E) of the Ministry of Mines, published in the Gazette of India Extraordinary, Part II, Section 3, sub-section (ii), No. 4459, Gazette identifier CG-DL-E-22082026-275676. Because Section 1(2) of the Amendment Act required an appointed date, the assent-default rule in Section 5 of the General Clauses Act, 1897 was displaced. The notification appointed the date of its own publication, and brought the whole Act into force at once.

What did the Supreme Court hold in *Mineral Area Development Authority v. Steel Authority of India*?

On 25 July 2024, in a decision bearing neutral citation 2024 INSC 554, a nine-judge Bench held by 8:1 — Justice B.V. Nagarathna dissenting — that royalty payable under Section 9 of the MMDR Act, 1957 is not in the nature of a tax; overruled the seven-judge decision in India Cement Ltd. v. State of Tamil Nadu; and affirmed that Entry 50 of List II confers on State legislatures the competence to tax mineral rights. Entry 50 is qualified: the power is subject to any limitations imposed by Parliament by law relating to mineral development. On 14 August 2024 the same Bench fixed the temporal reach — recovery of past dues on transactions from 1 April 2005, interest and penalty waived for the period before 25 July 2024, and payment in staggered instalments over twelve years commencing 1 April 2026.

Why is the extension to "mineral bearing lands" the harder constitutional question?

Because it moves the analysis from Entry 50 to Entry 49. Entry 50 is conditional on its face, so a bar on State taxation of mineral rights is an exercise of a carve-out written into the entry. Taxes on lands and buildings fall under Entry 49 of List II, which carries no subject-to-Parliament qualification. Where a State levy is in substance a tax on land, the Entry 50 carve-out supplies no authority, and the Union must rely on the widened Section 2 declaration under Entry 54 of List I — an entry the Supreme Court has characterised as regulatory rather than fiscal. Apply the pith-and-substance test to identify which entry the levy truly engages.

Can Parliament validly nullify a judgment by legislation?

It may remove the basis on which a judgment proceeded; it may not declare a judicial decision ineffective by fiat. Section 9D(2) sits on that line, because it operates "notwithstanding … any judgment, decree or order of any court" against liabilities fixed by a nine-judge Bench and a recovery schedule the Court itself calibrated. The outcome turns on whether a court reads the provision as altering the legal foundation of the liability or as nullifying the decree. No decision testing Section 9D has been traced as at 8 September 2026, so treat this as an open question and argue it, rather than asserting a conclusion.

Does Section 9D require States to refund mineral levies already collected?

No. The proviso to Section 9D(2) expressly states that any tax, cess or other levy on mineral rights or mineral bearing lands already deposited with, or recovered by, the State Government before commencement shall not be liable to be refunded. The invalidating effect operates only on amounts that remained undeposited and unrecovered at commencement on 22 August 2026.

The commencement date of 22 August 2026 and all Gazette particulars (S.O. 4642(E); Part II, Section 3, sub-section (ii); issue No. 4459; identifier CG-DL-E-22082026-275676; F. No. M.VI-11/5/2024-Mines VI; signature of Dr. Veena Kumari Dermal, Additional Secretary; masthead "NEW DELHI, SATURDAY, AUGUST 22, 2026/SHRAVAN 31, 1948") are read from the Gazette PDF itself, whose text was downloaded and extracted for Veritect's report of 22 August 2026. Because the notification appoints the date of its own publication as the commencement date, the Gazette masthead date is itself the operative legal fact and was read from the document rather than inferred. The clause-by-clause content of the Amendment Act (Sections 2, 3(ada), 9D(1), 9D(2) and its proviso, and 13(2)(ta)), the Bill number (154 of 2026), the introduction date of 10 August 2026 and the Statement of Objects and Reasons dated 7 August 2026 are taken from the Bill as introduced in the Lok Sabha. The particulars of Mineral Area Development Authority v. Steel Authority of India — neutral citation 2024 INSC 554, date 25 July 2024, nine-judge Bench, 8:1 majority, dissent of Justice B.V. Nagarathna, the holding that royalty under Section 9 is not a tax, the overruling of the seven-judge decision in India Cement Ltd. v. State of Tamil Nadu, the affirmation of State competence under Entry 50 of List II, and the holding that Parliament cannot itself tax mineral rights under Entry 54 of List I — are taken from the Supreme Court's own PDF at api.sci.gov.in as quoted in Veritect's report of 17 August 2026. The 14 August 2024 temporal order (recovery on transactions from 1 April 2005; interest and penalty waived for the period before 25 July 2024; staggered instalments over twelve years commencing 1 April 2026) is taken from the same report. Provenance qualification recorded (§5.10): the Act number "20 of 2026" is stated here as recorded in Veritect's report of the commencement notification of 22 August 2026, which read that notification's text; Veritect's earlier report of 17 August 2026 expressly recorded that no Act number for 2026 had been traced on egazette.gov.in or indiacode.nic.in as at 18 August 2026. Aspirants should verify the Act number against the gazetted Act text before quoting it. Second gap recorded: the texts of Entries 23, 49, 50 of List II and Entry 54 of List I are paraphrased, not quoted, save for the Entry 50 qualifier "subject to any limitations imposed by Parliament by law relating to mineral development", which is quoted as it appears in the sourced material. The Constitution of India is not held in the local Bare Acts mirror, and indiacode.nic.in returned HTTP 404 when consulted on 8 September 2026, so the entry texts could not be verified verbatim in this session; read the Seventh Schedule from the primary text before quoting it in an answer. Third gap recorded: no judicial decision testing the validity of Section 9D has been traced as at 8 September 2026 — that is a research gap and expressly not a finding that none exists, and no view on Section 9D's constitutionality is asserted in this digest.
