Supreme Court to Hear Suo Motu Case on Aravalli Hills Definition and Protection

New Delhi, Dec 2025 : The Supreme Court is set to hold a crucial suo motu hearing on Monday on issues related to the definition, conservation, and long-term protection of the Aravalli Hills, one of India’s most ecologically fragile and oldest mountain ranges. The hearing comes amid mounting concerns over recent policy decisions, mining activities, and the government’s stated commitments to safeguard the region.

According to the causelist published on the Supreme Court’s official website, a Bench comprising Chief Justice of India Surya Kant, Justice J.K. Maheshwari, and Justice A.G. Masih will hear the suo motu writ petition titled “In Re: Definition of Aravalli Hills and Ranges and Ancillary Issues” on December 29. The matter has been taken up by the apex court on its own motion in view of widespread environmental concerns and the need for clarity on legal and administrative protections for the Aravalli range.

The Aravalli Hills stretch from Delhi through Haryana, Rajasthan, and Gujarat, playing a critical role in regulating climate, preventing desertification, recharging groundwater, and supporting biodiversity. Environmentalists have long warned that unchecked mining, urban expansion, and regulatory dilution could cause irreversible damage to the range.

In a significant step aimed at curbing environmental degradation, the Union Ministry of Environment, Forest and Climate Change (MoEF&CC) has recently directed all concerned state governments to impose a complete ban on the grant of new mining leases in the Aravalli region. The Ministry clarified that the ban applies uniformly across the entire Aravalli landscape, from Delhi to Gujarat, with the stated objective of preserving the range as a continuous geological ridge and putting an end to unregulated and illegal mining activities.

Further strengthening the conservation framework, the Ministry has instructed the Indian Council of Forestry Research and Education (ICFRE) to identify additional areas across the Aravalli range where mining should be strictly prohibited. These zones would be in addition to areas already notified or restricted by the Centre, indicating a broader and more precautionary approach to environmental protection.

However, the issue has also triggered political debate. Congress leader and former Union Environment Minister Jairam Ramesh has raised serious objections to what he described as a recent “redefinition” of the Aravalli Hills. In a letter dated December 28 to Union Environment Minister Bhupender Yadav, Ramesh expressed concern that the new definition appears to limit the classification of the Aravallis to landforms with an elevation of 100 metres or more.

Sharing the letter on social media platform X, Ramesh said that the redefinition could have far-reaching and potentially damaging consequences. He stated that there are widespread concerns about how such a narrow definition may exclude large portions of the Aravalli landscape from legal and environmental protection.

In his communication to the Union Minister, Ramesh posed four specific questions seeking clarity on the rationale, scientific basis, and legal implications of the revised definition. He argued that any dilution or ambiguity in defining the Aravallis could open the door to increased mining, construction, and ecological harm.

The Supreme Court’s hearing is therefore being closely watched by environmental experts, policymakers, and civil society groups, as it may shape the future legal framework governing the protection of the Aravalli Hills and set important precedents for ecological conservation across the country.
