"Autonomous District Councils under the Sixth Schedule complicate uniform enforcement of national environmental law." Critically analyse in the context of coal mining in Meghalaya.

The Sixth Schedule vests land and its management in Autonomous District Councils (ADCs) of Meghalaya, Assam, Tripura and Mizoram [1]. Since Meghalaya's coal lies largely under community and clan ownership, enforcing national mining and environmental law there becomes negotiated rather than automatic — though the complication is administrative more than constitutional.

How ADC autonomy complicates enforcement

• Fragmented ownership: land management powers under the Sixth Schedule leave coal spread across thousands of small community and family plots, outside a conventional lease-based regulatory grid [1].
• Missing duty-holder: without identifiable lessees, statutory obligations of mining plans, environmental clearance and mine closure lack an accountable party — hence unscientific rat-hole pits proliferated and remain unsealed.
• Capacity deficit: ADCs possess customary authority but little technical or environmental machinery; the State pleads customary rights, and policing scattered pits is administratively infeasible.
• Judicial substitution: the NGT's 2014 ban and the court-appointed Justice B.P. Katakey Committee, mandated to oversee environmental restoration and victim rehabilitation from a ₹100-crore State deposit, show courts filling an executive vacuum [2].

Why the constitutional design is not the real barrier

• The Supreme Court (2019) held that the MMDR Act, 1957 and its rules govern mining in Meghalaya notwithstanding community ownership — the law is already uniform [2][3].
• Central environmental statutes and the MMDR framework carry no ADC exemption; the Sixth Schedule confers autonomy in land administration, not immunity from national regulation [3].
• The Ministry of Coal's facilitation of scientific coal mining blocks in Meghalaya proves regulated, lease-based mining is legally workable within Sixth Schedule areas [4].
• The persisting gap — no mine-closure policy, weak scrutiny of coke-oven units — reflects State-level inaction, not constitutional obstruction.

Autonomy thus raises the cost of enforcement rather than removing the obligation. A tripartite Centre–State–ADC framework for cluster leasing, mine closure and restoration, with ADCs as co-implementers rather than adversaries, can reconcile tribal self-governance with Article 48A's mandate and India's SDG-15 commitments.
