Trace the evolution of the MMDR Act since 1957, highlighting how recent amendments (2015, 2023, 2025, 2026) have reshaped mineral governance in India.

The Mines and Minerals (Development and Regulation) Act, 1957, administered by the Ministry of Mines, is India's parent mineral law, resting on Entry 54 of the Union List [2]. From a discretionary, licence-based regime, it has evolved through successive amendments into an auction-driven, exploration-focused and increasingly Centre-regulated framework.

From discretion to auctions (1957–2015)

• The 1957 Act vested regulation of mines and mineral development in the Union, with States granting concessions largely through first-come-first-served discretion.
• The 2015 amendment replaced this with mandatory auction of mineral concessions, introducing transparency and competitive price discovery in allocation.

Deepening exploration and private entry (2021–2023)

• Amendments of 2021 and 2023 created the exploration licence for deep-seated and critical minerals, opening greenfield exploration to private and junior explorers [3].
• Parliament also enacted the Offshore Areas Mineral (Development and Regulation) Amendment Act, 2023, extending an auction-based regime to offshore blocks.

Liberalising leases and funding exploration (2025)

• The MMDR Amendment Act, 2025 allowed inclusion of new/additional minerals in existing leases, removed the cap on sale of minerals from captive mines, and renamed the National Mineral Exploration Trust as the National Mineral Exploration and Development Trust, widening its remit to offshore and overseas exploration [3].
• Lessee contribution to the Trust was raised from 2% to 3% of royalty, expanding exploration finance [3].

Recasting mineral fiscal federalism (2026)

• Responding to the Supreme Court's 2024 Mineral Area Development Authority ruling upholding State power to tax mineral rights, the MMDR Amendment Act, 2026 bars State taxes, cesses or levies on mineral rights and the newly defined "mineral-bearing lands" except as the Centre prescribes [1][2].
• Unrecovered pre-amendment State levies are invalidated, though collected sums are non-refundable — raising concerns of legislative competence and Article 14 equity [2].

The trajectory thus moves from discretionary allocation to transparent auctions, and now to a nationally uniform fiscal framework. Sustaining investor certainty for critical-mineral security while honouring cooperative federalism will require the Centre to prescribe conditions consultatively, ideally through the GST Council-style institutional consensus that has served India's fiscal union well.
