New Delhi, October–November 2025: A recent decision by the Supreme Court of India to accept a new 100-metre elevation-based definition of the Aravalli Hills has reopened long-running concerns over mining regulation, environmental safeguards, and the court’s own past jurisprudence. Documents and filings placed before the court show that the shift came despite explicit cautions from its statutory advisory body, the Central Empowered Committee (CEC), only weeks earlier. The CEC is a Supreme Court-mandated body, established in 2002, that acts as an environmental watchdog, monitoring compliance with court orders on forest, wildlife, and conservation matters, conducting field inspections, and submitting reports to the SC to aid its judicial oversight - formed in 2002 under the landmark N. Godavarman Thirumulpad v. Union of India case (1997) to manage complex environmental litigation and reconstituted and given permanent statutory status in 2023, bringing it under the administrative control of the Ministry of Environment, Forest and Climate Change (MoEFCC).

What Changed: From Slope-Based Protection to Height-Based Cut-Off

On November 20, 2025, the Supreme Court approved a definition of the Aravalli Hills based on elevation — land rising 100 metres or more from local ground level — as proposed by a panel led by the Union Environment Secretary. This replaced the earlier benchmark developed by the Forest Survey of India (FSI), which identified Aravalli terrain using satellite imagery and a 3-degree slope criterion, capturing hills, valleys, and associated ecological systems across Rajasthan and other states.

The acceptance of the 100-metre norm marked a decisive departure from the FSI’s terrain-based approach that had guided court oversight of mining in the Aravallis for more than a decade.

CEC’s Warning Before the Decision

Two weeks before the court accepted the new definition, the CEC had cautioned against proceeding with mining lease renewals in areas falling within the Aravallis as mapped by the FSI. In communications dated October 14 and November 7, the committee underlined that 164 mining leases in Rajasthan, spanning about 76 square kilometres, were either wholly or largely located within the FSI-defined Aravalli polygons.

The CEC advised that these leases should not be approved or processed further until the court finalised a definition of the Aravalli Hills, stressing the need to protect the region’s fragile ecology. Its assessment was based on a detailed spatial analysis using mining lease maps, FSI hill polygons, and satellite overlays.

Why the New Definition Matters for Mining

According to officials in Rajasthan’s forest department, most of the 164 leases flagged by the CEC lie below the 100-metre elevation threshold, a benchmark the state has followed since 2006 while issuing mining permissions. As a result, once the Supreme Court accepted the 100-metre definition, these mines effectively fell outside the newly defined Aravalli boundary, potentially clearing the way for renewals or extensions that had earlier been constrained by court oversight.

This has made the court’s November 20 order immediately consequential, even though a final decision on individual lease renewals is still pending.

A Sharp Contrast With the Court’s 2010 Position

The 2025 acceptance of the 100-metre norm stands in stark contrast to the Supreme Court’s own ruling in February 2010, when it rejected Rajasthan’s height-based definition of the Aravallis. At that time, the court directed the FSI to conduct a comprehensive survey of the entire hill range using satellite data, explicitly stating that the assessment should not be confined to peaks above 100 metres.

That exercise led to the adoption of the 3-degree slope benchmark, under which the FSI identified over 40,000 square kilometres across 15 districts of Rajasthan as part of the Aravalli system. Subsequent CEC reports, accepted by the court, documented extensive ecological damage, including findings that 31 of 128 sampled hills had disappeared entirely due to mining and associated activity.

How the Shift Came About

When the Supreme Court revisited the issue in May 2024 to arrive at a common Aravalli definition for Rajasthan, Haryana, Gujarat, and Delhi, both the FSI and the CEC were part of the expert process. The FSI even led a technical sub-committee alongside the Geological Survey of India and Survey of India.

However, filings show that the Ministry of Environment, Forest and Climate Change leaned heavily on the states’ preference for a uniform, elevation-based standard. By October 2025, the ministry informed the court that all four Aravalli states had agreed to continue with the 100-metre criterion already used by Rajasthan for regulating mining.

Despite a dissent note from the CEC and detailed submissions by the court’s amicus curiae, the Supreme Court accepted the ministry’s recommendation.

What Is the Management Plan for Sustainable Mining — and Why It Matters Now

At the centre of the Supreme Court’s latest intervention on the Aravalli Hills is a requirement that has received less public attention than the new definition but carries far greater practical weight: the preparation of a Management Plan for Sustainable Mining (MPSM).

The MPSM is a court-mandated planning exercise, not a policy proposal of the government. It is intended to map the Aravalli landscape as an integrated ecological system and determine, through scientific assessment, where mining is absolutely prohibited, where restoration is required, and whether any limited extraction can ever be contemplated without irreversible damage.

Crucially, the Supreme Court has directed that no new mining leases or renewals may be granted until this plan is prepared and placed before the Court. The acceptance of a definition, therefore, does not trigger fresh permissions; it only sets the stage for a subsequent planning exercise that remains under judicial supervision.

Why the Aravalli Issue Is Now Effectively in a Holding Pattern

The requirement of an MPSM has placed the entire Aravalli mining question into a state of procedural suspension. Until the plan is completed, examined, and approved, authorities are barred from issuing new mining approvals, even in areas that might appear to fall outside the newly accepted 100-metre elevation threshold.

This holding pattern reflects the Court’s long-standing approach in environmentally sensitive regions: rather than impose a permanent ban, which it has warned can push extraction underground, the Court freezes activity and demands a scientific framework that can withstand scrutiny.

In practical terms, this means that the November 20 acceptance of a definition does not unlock mining activity. Instead, it pauses decision-making and defers the next set of determinations to a later stage, when the MPSM is ready for judicial review.

Why the New Definition Does Not Automatically Open Areas Below 100 Metres

A major source of public anxiety has been the fear that areas lying below the 100-metre elevation benchmark could immediately become eligible for mining. The Court’s directions, however, make clear that definition and permission are not the same thing.

The elevation-based definition is meant to provide a common reference point for mapping the Aravalli system. It does not, by itself, authorise mining in any location. Even land that does not meet the 100-metre criterion remains subject to the blanket freeze on new leases until the MPSM is approved.

Whether such areas are ultimately classified as core, buffer, restoration, or potential activity zones will depend on how the MPSM evaluates inter-hill connectivity, base slopes, ecological functions, and cumulative impacts. Until that evaluation is complete, no part of the Aravalli landscape — above or below 100 metres — can be opened up through administrative action.

Why the Matter Is Back Before the Supreme Court — and What Today’s Hearing Signals

The Aravalli issue is no longer in a notional holding pattern alone — it has formally returned to the Supreme Court of India for further consideration today, underscoring that the November 20 acceptance of a uniform definition did not close the case.

Today’s hearing also unfolds against a backdrop of unusually visible public scrutiny. The definitional shift triggered sustained media and civil-society outrage, with even former Chief Justice BR Gavai being directly questioned by television anchors on the implications of the Aravalli ruling — a rare moment that underscored how deeply the issue had entered public discourse. That pressure has sharpened focus on the Court’s next steps, lending added significance to the matter’s re-listing today.

The immediate focus of the hearing is likely to be: whether the November 20 order should be stayed, if not - then how the newly accepted definition is to be operationalised, how pending mining lease matters are to be handled in the interim, and how the court’s own environmental safeguards — particularly the preparation of a Management Plan for Sustainable Mining (MPSM) — are to be sequenced and supervised.

By listing the matter for hearing even before the MPSM is prepared, the Court has signalled that it intends to retain active oversight rather than allow the definitional shift to automatically translate into administrative outcomes. This stage allows the bench to clarify ambiguities, address concerns raised by expert bodies such as the Central Empowered Committee, and reiterate the limits of executive discretion while the planning exercise is underway.

Past Aravalli proceedings show that such hearings often function as course-correction points: the Court uses them to restate what remains frozen, what remains open, and what must come back for approval. Today’s listing therefore reinforces a central point that can be lost in headline coverage — the dispute has moved into its next judicial phase, not its final one, and the contours of mining regulation in the Aravallis remain subject to continuing court scrutiny.

Why This Matters

The change in definition effectively resets over fifteen years of court-supervised environmental regulation in the Aravalli range. By narrowing the legal footprint of what constitutes the hills, the decision alters which areas fall under stricter scrutiny for mining and quarrying.

Beyond its immediate impact on pending mining leases, the episode raises broader questions about continuity in environmental jurisprudence, the weight accorded to expert bodies such as the CEC and FSI, and how ecological risk is balanced against administrative uniformity. For a hill system long described by the court itself as ecologically degraded and critical to north-western India’s environmental stability, the implications of this definitional shift are likely to extend well beyond the current round of mining approvals.

Notes and Context: The reporting foregrounds documentary evidence, timelines, and internal court processes to show how the Supreme Court’s acceptance of the 100-metre definition diverged from prior jurisprudence and expert advice. By highlighting the Central Empowered Committee’s warnings, the status of pending mining leases, and the contrast with the Court’s 2010 orders, the coverage frames the issue as one of judicial consistency and environmental governance rather than political contestation alone.
Indian Express (historical explainer)	Continuity-Audit Ruru	4
Notes and Context: The second article explicitly audits the Court’s past positions, reconstructing the evolution of the Aravalli definition from 2010 onward. Its emphasis lies on precedent, expert methodology (FSI slope mapping), and ecological loss documented over time, creating a fact-heavy narrative that invites readers to assess the implications of the present shift against a long arc of court-supervised protection.

Comparative Analysis

Convergence:

Both articles agree that the Supreme Court accepted a 100-metre elevation-based definition of the Aravalli Hills on November 20, 2025, despite earlier reliance on the Forest Survey of India’s slope-based mapping, and that this shift has direct implications for pending mining leases in Rajasthan.

Frame Divergence:

The divergence lies in what each piece treats as the core problem: one centres on immediate regulatory consequences, while the other interrogates judicial memory and precedent.

Indian Express — Mining-Impact Lens:

The first article frames the definitional change through its downstream effects on mining governance. It closely tracks the Central Empowered Committee’s analysis of 164 mining leases, the timing of its cautionary reports, and how the newly accepted definition could reclassify lease areas that were previously treated as part of the protected Aravalli system. The emphasis is on regulatory consequence and sequencing — what the Court knew, what it was advised, and what changed once the elevation benchmark replaced the slope criterion.

Indian Express — Jurisprudential Continuity Lens:

The second article steps back to situate the November 2025 decision against the Court’s own history. It reconstructs the 2010 rejection of the same 100-metre benchmark, the rationale for adopting slope-based mapping, and the ecological findings that followed. The framing invites readers to view the present order not merely as a policy adjustment, but as a departure from a long-standing judicial approach that treated the Aravallis as an integrated ecological system rather than a set of discrete hill peaks.

Rida Synthesis

Read together, the coverage shows that the Aravalli controversy is not only about mining or definitions, but about how environmental protection is mediated through judicial process over time. The definitional shift matters because it alters the legal map against which future decisions will be tested, even as actual permissions remain frozen pending further court-mandated planning.

Equally important is the timing. The Court’s decision has landed amid sustained public and media scrutiny, expert dissent, and now an active return of the matter to the courtroom. This convergence — expert caution, public outrage, and judicial re-engagement — reinforces that the issue is in a transitional phase, where outcomes will be shaped less by a single metric than by how transparently and conservatively the next stage of court-supervised planning is conducted.
