What Happened
- A vacation bench of the Supreme Court comprising Chief Justice Surya Kant, Justice J.K. Maheshwari, and Justice A.G. Masih directed the Ministry of Environment, Forest and Climate Change (MoEFCC) and other stakeholders to suggest names of domain experts for a new expert panel that will define the boundaries of the Aravalli Hills and Aravalli Range.
- The court "put in abeyance" (suspended) its earlier November 2025 order that had accepted the Central Environment Ministry's definition of the Aravalli Hills, after concerns were raised that the definition was too narrow and would expose large portions of the ecologically sensitive range to mining and real estate development.
- The amicus curiae submitted suggestions to the bench on the aspect of definitions of the Aravalli hills and ranges; contesting parties were directed to submit written notes by 10 March 2026, with no further extensions permitted.
- The court maintained a status quo order — halting all activities including mining in the disputed areas — until the expert panel's findings are accepted and a definitive boundary is established.
- States have until end of March 2026 to submit their positions.

Aravalli Range — Ecological and Geological Significance
The Aravalli Range is one of the oldest geological formations on Earth, estimated to be approximately 1.5–2 billion years old — predating the Himalayas by over a billion years. Stretching approximately 692 km from Gujarat through Rajasthan, Haryana, and into Delhi, it serves multiple critical ecological functions that extend far beyond the hills themselves.
- Age: Approximately 1.5–2 billion years (Pre-Cambrian origin); one of the world's oldest fold mountain systems
- Extent: 692 km from Gujarat (Palanpur) through Rajasthan, Haryana to Delhi
- Highest peak: Guru Shikhar in Rajasthan (1,722 m above sea level)
- Desertification barrier: Acts as a wall preventing the Thar Desert from advancing eastward into the Indo-Gangetic Plains
- Groundwater recharge: Fractured rocks recharge aquifers supplying Delhi, Gurugram, Faridabad, and large swathes of Haryana and Rajasthan
- Biodiversity: Supports dry deciduous forests, grasslands, and wetlands; unique Saharan-Peninsular-Oriental biodiversity overlap zone
- Forest cover: Severely degraded — Forest Survey of India found only 8.7% of mapped hills (1,048 out of 12,081) meet the "100 metres above local relief" criterion adopted by the Supreme Court in 2022
Connection to this news: The definition of "Aravalli" is not merely geographical — it determines which land parcels are protected from mining and construction. A narrower definition (accepted by the Ministry in November 2025) would have removed protection from thousands of hills, enabling mining and real estate development with devastating ecological consequences.
Supreme Court's Role in Environmental Governance — Key Precedents
The Supreme Court of India has been a primary driver of environmental protection, often acting where the executive and legislature have been slow. The Aravalli case is part of a long line of judicial interventions on forest and land degradation.
- MC Mehta v. Union of India (1987 onwards): Landmark environment litigation series; established the "polluter pays" and "precautionary principles" in Indian environmental law
- T.N. Godavarman Thirumulpad v. Union of India (1995): The "Forest Case" — SC expanded the definition of "forest" to include all areas that biologically function as forests, regardless of ownership or legal status; created a template for the Aravalli definition debate
- Arjun Gopal v. Union of India (2018): SC restricted firecrackers to reduce air pollution, demonstrating willingness to regulate private economic activity for environment
- In the Aravalli case, the SC in November 2020 halted all mining in Haryana's Aravalli region; in 2022, it directed all states to adopt a uniform "100m relief" criterion
- The present (2026) panel formation follows the SC's recognition that a purely administrative definition (by MoEFCC) was inadequate and needed independent expert determination
- Amicus Curiae: Court-appointed friend of the court who assists in complex or public interest matters
Connection to this news: The SC's decision to stay its own November 2025 order and constitute an independent expert panel is unusual and significant — it signals that the court believes the Ministry's definition was potentially environment-compromising, and that technical expertise (ecology, geology, hydrology) must inform legal boundaries.
Mining Regulation and Forest Governance in India
Mining in ecologically sensitive areas is governed by a complex web of statutes: the Mines and Minerals (Development and Regulation) Act 1957, the Forest Conservation Act 1980, the Environment Protection Act 1986, and state-specific mining regulations.
- MMDR Act 1957 (amended 2021, 2023): Governs exploration and mining leases; amended to allow commercial mining in coal and extend auction mechanisms to all minerals
- Forest Conservation Act 1980: Any diversion of forest land for non-forest purposes (including mining) requires prior approval of the Central Government — the "forest clearance" process
- Environment Impact Assessment (EIA) Notification 2006: Mining projects above threshold capacity require Environmental Clearance (EC) and public consultation
- Category A (large mining) projects require approval from Expert Appraisal Committee (EAC) under MoEFCC
- Designated Eco-Sensitive Zones (ESZ): Buffer zones around Protected Areas where mining is prohibited or heavily restricted; ESZ notifications for Aravalli regions remain incomplete
- Compensatory Afforestation Fund (CAMPA): Funds collected from industries for forest diversion must be used for afforestation; total corpus exceeded ₹50,000 crore
Connection to this news: The Aravalli boundary definition directly determines the applicability of Forest Conservation Act protections and EIA requirements. If an area is outside the "Aravalli" boundary, mining companies can seek clearances that would otherwise be far more difficult or impossible to obtain.
Environmental Federalism and Centre-State Disputes
The Aravalli case highlights a recurring tension in Indian environmental governance: states prioritise economic development (mining revenues, real estate) while the Centre's constitutional obligations and court mandates push for environmental protection.
- Schedule VII (Constitution): "Forests" is a Concurrent List subject (Entry 17A) — both Centre and states can legislate, but Central law prevails in conflict
- Rajasthan and Haryana position: Both states have historically pressed for narrower Aravalli definitions to enable mining and development
- Delhi's position: Supports broader protection as Aravallis are critical for Delhi's groundwater and air quality
- Principal stakeholders in the SC case: States of Rajasthan, Haryana, Gujarat, Delhi; Central Government (MoEFCC); mining industry associations; environmental NGOs
- Sustainable Development Goal 15 (Life on Land): India's Aravalli degradation directly contradicts SDG 15 commitments on halting land degradation and restoring ecosystems
Connection to this news: The court's direction to the Ministry (rather than accepting the Ministry's own definition) reflects a judicial check on executive discretion in environmental matters, particularly where state-level economic interests may have influenced the Central Ministry's position.
