What Happened
- An amicus curiae (court-appointed independent legal adviser) has informed the Supreme Court that a committee led by the Ministry of Environment, Forest and Climate Change (MoEF) Secretary suppressed or structurally pre-empted the independent assessment of the Forest Survey of India (FSI) regarding the definition of the Aravalli Hills.
- The controversy relates to a November 20, 2025 Supreme Court order that accepted a committee-recommended definition of the Aravalli Hills under which landforms below 100 metres in height are excluded from the range.
- The FSI's internal assessment found that under this 100-metre threshold definition, only 1,048 out of 12,081 hills in Rajasthan would qualify — leaving over 90% of Aravalli landforms without legal protection.
- The amicus argued that by including FSI representatives within the committee itself, the government structurally prevented FSI from functioning as an independent expert voice before the court.
- The consequence of the 100-metre threshold: vast tracts of the Aravalli foothills and lower ridges — ecologically sensitive areas protecting Delhi and surrounding regions from desertification and dust storms — could be opened to mining.
- Following these objections, the Supreme Court kept its November 20 order in abeyance and constituted a new high-powered expert committee to review the environmental impact of the earlier committee's recommendations.
Static Topic Bridges
The Aravalli Hills: Ecological Significance and the Definition Dispute
The Aravalli Range is one of the world's oldest fold mountain systems, running approximately 800 km from Gujarat through Rajasthan, Haryana, and into Delhi. Its ecological function is disproportionately large relative to its height.
- The Aravallis form a natural barrier against the Thar Desert's eastward advance — their degradation has been directly linked to increasing dust storms and desertification affecting Delhi and the National Capital Region.
- The range is home to significant biodiversity including leopard, sloth bear, Indian pangolin, and numerous migratory birds; it hosts several wildlife sanctuaries.
- The definition dispute originated because "Aravalli Hills and Ranges" had never been formally legally defined — earlier Supreme Court orders protecting the Aravallis (dating to the 1990s) used the term without a precise boundary definition, creating ambiguity that mining interests exploited.
- The 100-metre threshold definition is contested by ecologists who argue that elevation is the wrong metric: connectivity, slope, vegetation cover, and hydrological function are more relevant to determining what constitutes the "range."
Connection to this news: The amicus curiae's submission goes to the heart of the definition battle — arguing that the committee's process was captured by interests favouring a narrow definition (which would open up more land to mining), with FSI's broader ecological assessment deliberately marginalized.
Forest Survey of India (FSI): Role and Independence
The Forest Survey of India (FSI) is a government body under the MoEF, established in 1981 and headquartered at Dehradun. Its statutory mandate is to assess, monitor, and report on India's forest and tree cover.
- FSI publishes the India State of Forest Report (ISFR) every two years, which is the authoritative national assessment of forest cover changes.
- FSI uses satellite-based remote sensing combined with ground-truth verification to map forest cover; it also prepares thematic maps for land use, biodiversity, and carbon stock assessments.
- FSI contributes to India's reporting under UNFCCC on forest carbon sequestration and emissions — making its data internationally significant.
- As a body under MoEF, FSI is not fully independent of the ministry; its findings can be influenced by the ministry's policy positions, creating potential conflicts of interest when FSI data challenges ministerial-level decisions.
Connection to this news: The amicus curiae identified precisely this structural dependency: by making FSI a member of the MoEF-led committee, the ministry ensured that FSI's potentially inconvenient assessment (that the 100-metre threshold would exclude most Aravalli hills) was incorporated into the committee's deliberations and made to appear as consensus — rather than surfacing as independent expert dissent before the Supreme Court.
Amicus Curiae in Environmental Litigation: Role and Significance
An amicus curiae ("friend of the court") is an independent expert, advocate, or organisation that assists the court by providing information and legal arguments when a case involves complex technical or policy issues. In India, the Supreme Court frequently appoints amicus curiae in public interest litigation (PIL) cases involving environment, forests, and tribal rights.
- The amicus is not a party to the case but submits reports, analyses, and recommendations to assist the court in reaching a well-informed decision.
- In environmental cases, the Supreme Court has relied heavily on amicus curiae reports — notably in cases involving forest conservation, mining, and pollution.
- The amicus curiae in forest cases often works alongside the Central Empowered Committee (CEC), another court-appointed monitoring body for forest-related matters.
- The relationship between the amicus, the CEC, and government ministries in forest litigation is complex: the amicus is expected to be fully independent, while the CEC has quasi-governmental status.
Connection to this news: The amicus curiae's report to the Supreme Court carried enough weight that the court suspended its own earlier order — an unusual step that signals the court takes the suppression allegation seriously. The amicus effectively served as the institutional check on what might otherwise have been an unchallenged executive recommendation.
Supreme Court's Role in Forest and Environmental Protection
The Supreme Court of India has been an active guardian of forest and environmental protection since the 1990s, issuing landmark orders that created institutional frameworks for forest governance outside the normal executive and legislative channels.
- T.N. Godavarman Thirumulpad v. Union of India (1995 onwards): A landmark case that transformed from a Kerala-specific forest encroachment matter into an ongoing supervisory jurisdiction over India's forests. The Supreme Court used this case to define what counts as "forest" (the Godavarman definition) and to regulate forest clearances.
- The court's 1996 order in Godavarman directed that no forest land could be diverted for non-forest purposes without prior approval under the Forest (Conservation) Act, 1980 and Supreme Court approval.
- Aravalli protection orders: The Supreme Court issued multiple orders through the 1990s and 2000s prohibiting mining in Aravalli forest lands in Haryana and Rajasthan — but their enforcement was undermined by definitional ambiguity about what constitutes "Aravalli."
- The court's decision to keep the November 2025 definitional order in abeyance and appoint a new expert committee reflects its continuing supervisory role in protecting Aravalli ecology.
Connection to this news: The Supreme Court's willingness to pause its own earlier order on the basis of the amicus curiae's report demonstrates the court's sensitivity to institutional capture in expert processes — and its recognition that the Aravalli protection framework it has built over three decades could be hollowed out by a definition that excludes most of the range from coverage.
