Supreme Court Aravalli Hills Case News: New Delhi: The Supreme Court on Monday stayed its recent judgment on the Aravalli Hills, saying that certain clarifications were necessary regarding the definitions it had approved last month. The Court also decided to constitute a new committee of experts to study the environmental impact of the recommendations made by an earlier panel, which was largely comprised of bureaucrats.
A Bench headed by Chief Justice of India (CJI) Surya Kant, along with Justices J.K. Maheshwari and A.G. Masih, passed the order in a suo motu case initiated amid widespread protests and concerns over the potential threat to the Aravalli range following the Court’s earlier ruling.
“We direct that the recommendations of the committee and the findings of the Supreme Court… shall remain in abeyance till then. Case to be taken up on January 21, 2026,” the Bench ordered, effectively staying the November 20 judgment and the recommendations it had endorsed.
The Court noted that it was necessary to seek an independent expert opinion to resolve ambiguities surrounding the definitions of the Aravalli Hills and the Aravalli Range, particularly in the context of mining regulation. It observed that the earlier ruling had generated confusion and apprehension, especially among environmentalists, regarding how the new definitions might be interpreted and implemented on the ground.
Solicitor General Tushar Mehta appeared for the Union government and told the Court that there had been several misconceptions about the judgment and the government’s role. “An expert committee was constituted and a report was given, which the court accepted,” Mehta said.
However, CJI Kant emphasised that the Court needed clearer and more definitive guidance. He said the expert committee would examine whether the restrictive demarcation approved earlier could potentially broaden the scope of areas where activities such as mining might be permitted. “An analysis of whether sustainable mining or regulated mining within the newly demarcated Aravalli area, notwithstanding regulated oversight, would result in any adverse ecological consequences… that aspect can be examined,” the CJI observed.
The Bench issued notice to the Union government as well as the concerned State governments and directed that, in the interim, both the earlier court directions and the previous committee’s recommendations would remain in abeyance.
In its order, the Supreme Court acknowledged that its November ruling had triggered a wave of challenges and requests for clarification. While it made clear that these challenges were not being entertained on scientific merit—recording that there were “no scientific reasons justifying any ex-facie acceptance” of individual objections—it conceded that there appeared to be gaps in the articulation of its earlier directions.
The Bench took note of what it described as a “significant outcry among environmentalists,” who feared that the newly adopted definitions could dilute protection for the Aravalli ecosystem. According to the Court, such public dissent could not be brushed aside, as it appeared to stem from perceived ambiguity and lack of clarity in the Court’s directives. In this backdrop, the Bench stressed the need for institutional caution before allowing the earlier directions to operate.
The Aravalli range spans parts of Delhi, Haryana, Rajasthan and Gujarat and is considered one of the oldest mountain systems in the world. The suo motu proceedings were initiated after protests erupted over the possible environmental impact of the Supreme Court’s acceptance of the committee’s recommendations.
Last month, the Court had approved an elevation-linked definition for identifying landforms as part of the Aravalli Hills for mining regulation. According to reports, this definition could exclude more than 90 per cent of the Aravalli region from the scope of mining restrictions.

The issue traces back to May 2024, when the Supreme Court, while hearing a matter related to illegal mining in the Aravallis, observed that different States had adopted varying definitions of the “Aravalli Hills” and “Aravalli Range.” To address this inconsistency, the Court constituted a committee, which submitted its report in October 2025.
The committee recommended that any landform in Aravalli districts with an elevation of 100 metres or more from the local relief be classified as an Aravalli Hill. It further defined the Aravalli Range as “two or more Aravalli Hills located within a proximity of 500 metres from each other,” measured from the outermost point on the boundary of the lowest contour line.

In its November 20 judgment, a Bench led by then CJI B.R. Gavai, along with Justices K. Vinod Chandran and N.V. Anjaria, accepted these definitions and endorsed a prohibition on mining in core or inviolate areas. At the same time, the Court declined to impose a complete ban on mining in the Aravallis, reasoning that a total prohibition could fuel illegal mining, mafia activity and criminality.
With Monday’s order, the Supreme Court has put those directions on hold, signalling a re-examination of the issue with greater emphasis on environmental impact, clarity of definitions and long-term ecological consequences.
