Chief Justice of India Surya Kant rejected a plea from the Supreme Court-appointed panel to extend the deadline for defining the Aravalli hills’ geographic and ecological boundaries. The CJI, who retires on February 9, 2027, questioned whether the request was designed to delay the outcome until after his tenure, and made it clear that no further extensions would be granted. The high-powered committee must now submit its final report by November 30, 2026.

## Bench Rejects Deadline Extension
A bench comprising Chief Justice Surya Kant, Justices Joymalya Bagchi, and V. Mohana refused the panel’s request for additional time until February 28, 2027. Instead, the committee—headed by Indian Council of Forestry Research and Education director general Kanchan Devi—is instructed to “work day and night” and finalize its report by **November 30, 2026**. The court emphasized that no more delays will be tolerated.
When Additional Solicitor General Aishwarya Bhati appeared for the Union government, the CJI asked pointedly: “They should have clearly asked for a date after my retirement … appears they are waiting for my retirement. We are not going to allow this.”

## Issues That Complicated the Definition
The panel had justified its extension request by citing the complexity of the task. In its **interim report submitted on August 31, 2026**, the committee explained that defining the Aravallis using just a terrain-based or elevation criterion was insufficient.
It is examining multiple domains:
– Ecological and geological data
– Hydrological impact
– Biodiversity
– Socioeconomic factors
– Stakeholder inputs
Field studies revealed important concerns like ecosystem health, changes in land use, hydrological disruptions, biodiversity loss, mining vulnerability, and disrupted landscape connectivity.

## Background: Earlier Definition & Its Fallout
In **November 2025**, a ministry-appointed committee proposed that any hill in the Aravalli districts rising at least 100 metres above the local relief would qualify as an Aravalli hill, and that a range would consist of two or more such hills within a 500-metre proximity.
Environmentalists strongly objected. They argued that large areas with ecological sensitivity could be excluded, leaving them vulnerable to mining. On **December 29, 2025**, the Supreme Court put that definition on hold and ordered a fresh expert assessment.
The December order also questioned the reliability of claims that only 1,048 out of 12,081 hills in Rajasthan met the 100-metre bar, and flagged issues around defining ecological continuity between hills.

## What the Panel Has Recommended So Far
The committee’s interim findings portray the Aravalli as a largely interconnected landscape. Key factors identified include:
– Ridge and hill formations, both large and small, showing spatial continuity
– Isolated hills or hillocks recognized for cultural, aesthetic, biodiversity, or hydrological value
– Inclusion of traditional pastures, wetlands, Orans, protected areas, critical catchments, and archaeological zones
– Emphasis on ecological corridors that connect with adjoining landscapes
Methodology involves:
– Geo-spatial assessment
– Comparison with the Forest Survey of India’s 2010 work and prior definitions
– Validation by specialists such as the National Remote Sensing Centre and ISRO

## Mandate from the Supreme Court: Stakeholders & Evidence
When rejecting the extension, the court also focused on stakeholder feedback. The panel must listen to a broad range of voices, including:
– Tribal communities in Rajasthan and Gujarat
– State governments (Delhi, Rajasthan, Haryana)
– Environmental NGOs
– Mining leaseholders
– Villagers and farmers whose livelihoods depend on the Aravalli ecosystem
The court emphasized that final decisions must rest on solid scientific evidence and resist narrow terrain-based definitions. The committee’s role extends beyond demarcating hills: it must evaluate ecological, socio-economic, cultural and hydrological aspects.

## Next Steps
The Supreme Court has set **December 2, 2026**, as the date for reviewing additional developments. By then, the committee is expected to have begun delivering interim reports on discrete issues so that the court can address them even before the overall final document is submitted.
This mandate comes with clear instructions: no more deadline extensions, full inclusion of stakeholder views, and strong scientific backing. The court has halted all mining operations in the Aravalli region until it receives and considers the panel’s final report.

## Significance & Potential Impact
The Supreme Court’s decision underscores the urgency of defining boundaries for Aravalli hills with precision. The chosen approach could impact:
– Environmental regulation and protection
– Mining policies
– Land use decisions
– Livelihoods of local communities and farmers
– Conservation outcomes amid climate, groundwater and biodiversity concerns
A clear definition backed by scientific rigour could help enforce environmental protections in what remains one of India’s most fragile landscapes. Missing or vague boundaries risk allowing extractive or developmental work to encroach upon vulnerable ecosystems.
