The National Green Tribunal’s ruling in this appeal establishes a critical boundary between precautionary environmental governance and arbitrary administrative denial. Where scientific evidence is inconclusive and mitigation measures are feasible, outright rejection of a mining proposal without considering conditional approval undermines the balance between development and ecology.
Background & Facts
The Dispute
The appellant, Raja Jebadoss, sought Environmental Clearance (EC) from the State Environmental Impact Assessment Authority (SEIAA), Tamil Nadu, for a rough stone and gravel quarry on his own land in Sy. Nos. 756/1 and 756/2, covering 6.02.5 hectares in Tuticorin District. The proposal was rejected on the grounds that the site lies 1.7 km from the Vallanadu Blackbuck Sanctuary, with concerns that blackbucks - listed under Schedule I of the Wildlife Protection Act - might stray into the mining area and become trapped, despite fencing.
Procedural History
- 2021: Appellant obtained a precise area order from the District Collector and a No Objection Certificate (NOC) from the District Forest Officer, confirming the site is 1.92 km from the sanctuary and 1.44 km beyond the notified Eco-Sensitive Zone (ESZ).
- 2022: The State Expert Appraisal Committee (SEAC) deferred consideration due to non-appearance of the appellant.
- 2023: SEAC rejected the proposal based on the opinion of a retired forest official who cited research suggesting blackbucks roam up to 5 km from the sanctuary.
- 2023: SEIAA adopted SEAC’s recommendation and rejected the EC application on 11.04.2023.
- 2024: Appeal filed before the National Green Tribunal.
Relief Sought
The appellant sought quashing of the rejection order and directed SEIAA to reconsider the proposal with appropriate environmental safeguards, rather than outright denial.
The Legal Issue
The central question was whether Environmental Clearance can be denied solely on speculative, unsubstantiated risk to wildlife, without evaluating the feasibility of imposing binding mitigation conditions under Environment (Protection) Act, 1986.
Arguments Presented
For the Appellant
The appellant’s counsel argued that:
- The proposed site lies beyond the legally notified Eco-Sensitive Zone (1.44 km from ESZ boundary), as confirmed by the District Forest Officer.
- The earlier quarry on Sy. No. 739/1, located closer to the sanctuary, had received EC with NBWL clearance and CSR-funded conservation measures, establishing precedent.
- The rejection relied on the opinion of a retired official, not peer-reviewed scientific data or field studies.
- The principle of proportionality and precautionary approach under Vellore Citizens Welfare Forum v. Union of India require mitigation, not prohibition, where harm is uncertain.
- The State’s own PCCF had opined that NBWL clearance was not required, as the site was outside the ESZ.
For the Respondent
The SEIAA contended that:
- Blackbucks are endangered and highly sensitive to anthropogenic disturbance.
- Research cited indicated blackbucks travel up to 5 km from the sanctuary, making proximity a legitimate concern.
- Past incidents of wildlife mortality in mining zones justified a precautionary stance.
- The absence of documented deaths does not negate potential risk.
- The decision was based on expert opinion within the SEAC’s mandate.
The Court's Analysis
The Tribunal examined the legal framework for Environmental Clearance under the Environment (Protection) Act, 1986, and the EIA Notification, 2006. It emphasized that the law does not mandate blanket prohibitions near wildlife habitats but requires a case-specific, science-based assessment with conditions.
"Rejecting the proposal solely on the ground of potential risk, without considering the imposition of stringent conditions, would render the decision arbitrary and violative of the principle of proportionality."
The Court distinguished between prohibited activities (e.g., mining inside a sanctuary) and regulated activities near protected areas. It noted that the ESZ notification explicitly permits regulated mining beyond the 2 km boundary, and the site here was 1.44 km beyond that limit.
The Tribunal rejected reliance on anecdotal or retired-official testimony without corroboration from field studies or wildlife monitoring data. It held that the burden of proof for imminent harm lies with the regulatory authority, not the proponent.
The Court also referenced T.N. Godavarman Thirumulkpad v. Union of India, which mandates a 1 km buffer around protected areas, but clarified that this applies to the sanctuary boundary - not the ESZ. The site was 1.92 km from the sanctuary, well beyond this threshold.
Crucially, the Tribunal observed that the appellant had previously complied with CSR obligations and conservation undertakings, demonstrating a track record of environmental responsibility. Denial without exploring conditions like fencing, buffer zones, night-time mining bans, or wildlife corridors was deemed procedurally flawed.
The Verdict
The appellant won. The National Green Tribunal set aside the rejection order and directed SEIAA to reconsider the proposal within six weeks, after affording the appellant a personal hearing and imposing appropriate environmental conditions to prevent wildlife entrapment.
What This Means For Similar Cases
Mitigation, Not Prohibition, Is the Legal Standard
- Practitioners must argue that Environmental Clearance denials based on hypothetical risks are invalid unless supported by empirical data.
- Regulatory bodies must document why mitigation measures (e.g., fencing, timing restrictions, monitoring) are insufficient before denying a project.
- Past compliance with conservation undertakings strengthens the proponent’s case for conditional approval.
ESZ Boundaries Are Legally Binding, Not Advisory
- The Eco-Sensitive Zone as notified under the EIA Notification is the legal boundary for regulation - not speculative distances.
- Any rejection based on distances beyond the notified ESZ must be challenged as ultra vires.
- District Forest Officers’ reports on site proximity carry evidentiary weight and must be reconciled with SEAC opinions.
Expert Opinions Require Scientific Rigor
- Retired officials’ opinions, without peer-reviewed research or field data, cannot override technical assessments.
- SEAC must record the basis of expert opinions and disclose underlying studies to the applicant.
- Tribunals will not accept vague references to "research papers" without citation or methodology.
