The National Green Tribunal’s suo motu intervention in response to alarming elephant mortality data in Kerala marks a watershed in wildlife conservation jurisprudence. By mandating systemic reforms in mortality tracking, disease surveillance, and infrastructure safety, the Tribunal has transformed passive monitoring into enforceable state obligations under environmental law.
Background & Facts
The Dispute
The Tribunal took cognizance of a 2024 article in The Hindu reporting 845 elephant deaths in Kerala over eight years, with a disproportionate number among calves and juveniles. The report highlighted Elephant Endotheliotropic Herpesvirus-Haemorrhagic Disease (EEHV-HD) as a leading natural cause and electrocution, train collisions, and explosive traps as preventable human-induced threats.
Procedural History
- July 19, 2024: Article published in The Hindu triggering suo motu action by the NGT Principal Bench.
- August 2024: Matter transferred to the Southern Zone Bench in Chennai and renumbered as O.A. No.259 of 2024 (SZ).
- September 12, 2024: MoEF&CC sought clarification from Kerala Forest Department.
- October 15, 2024: Kerala constituted a five-member Expert Committee to investigate mortality trends.
- February 3, 2026: Judgment reserved after detailed submissions from the Ministry and State.
Relief Sought
The Tribunal, acting suo motu, sought to compel institutional accountability for elephant mortality, demanding structured data collection, habitat-based interventions, and preventive infrastructure reforms to ensure long-term population viability.
The Legal Issue
The central question was whether the State and Central Governments have a legally enforceable duty under the Wildlife (Protection) Act, 1972 and the principles of sustainable development to establish mandatory, standardized systems for monitoring natural and human-induced elephant mortality, and to implement preventive, landscape-level conservation measures.
Arguments Presented
For the Petitioner (Suo Motu)
The Tribunal, acting as the public interest litigant, argued that the highest level of statutory protection afforded to the Asiatic elephant under Schedule I of the Wildlife (Protection) Act, 1972 imposes a non-delegable duty on the State to prevent avoidable mortality. The absence of a centralized database for natural causes like EEHV-HD, coupled with rising electrocution and transport deaths, constituted a failure to discharge obligations under Article 48A and Article 51A(g) of the Constitution. The Tribunal relied on Centre for Environmental Law v. Union of India to assert that ecological stability is a public trust requiring proactive state intervention.
For the Respondent/State
The Ministry of Environment, Forests & Climate Change and Kerala Forest Department acknowledged data gaps but contended that Project Elephant, now merged with Project Tiger, provided sufficient institutional mechanisms. They argued that mortality data was being collected at the state level and that EEHV-HD, as a natural disease, fell outside the scope of statutory intervention. They emphasized resource constraints and the absence of a legal mandate for a national mortality database.
The Court's Analysis
The Tribunal rejected the notion that natural mortality absolves the State of responsibility. It held that ecological stability is not merely a matter of population numbers but requires the protection of demographic integrity - particularly of vulnerable calves and juveniles. The Court emphasized that Project Elephant, though centrally funded, cannot function as a mere financial scheme; it imposes operational obligations to mitigate threats, whether natural or anthropogenic.
"The fact that mortality is currently balanced by recruitment does not negate the systemic failure to prevent preventable deaths or to monitor disease patterns that threaten long-term genetic viability."
The Tribunal distinguished State of H.P. v. Krishan Lal (which limited judicial intervention to clear statutory violations) by noting that the precautionary principle and polluter pays principle under the Environment (Protection) Act, 1986 require action even in the absence of conclusive scientific proof of imminent collapse. The Expert Committee’s findings - particularly the tripling of electrocution incidents and the correlation between dry-season stress and human-elephant conflict - established a clear nexus between habitat degradation and mortality.
The Court further held that the absence of a centralized database for natural causes like EEHV-HD was a procedural failure undermining evidence-based policy. The State’s reliance on ad hoc reporting was deemed insufficient under the right to a healthy environment recognized in Subhash Kumar v. State of Bihar.
The Verdict
The National Green Tribunal ruled in favor of ecological integrity. It held that mandatory mortality tracking, landscape-specific conservation plans, and infrastructure safety reforms are legally enforceable obligations under environmental law. The Court issued seven binding directions to the State and Central Governments to implement standardized surveillance, habitat augmentation, and preventive infrastructure measures.
What This Means For Similar Cases
Mandatory Mortality Auditing Is Now a Legal Standard
- Practitioners must now argue that any protected species with declining demographic trends triggers a duty to establish digitized, standardized mortality reporting under Section 3 of the Environment (Protection) Act, 1986.
- NGOs and forest departments can file compliance petitions if WAMAF or similar frameworks are not implemented.
Infrastructure Liability Extends to Power and Railways
- Electrocution and train collisions are no longer treated as accidents but as preventable environmental harms.
- Power utilities and Railways can now be joined as respondents in NGT proceedings for failing to retrofit infrastructure in wildlife corridors.
Disease Surveillance Is Part of Conservation Duty
-
EEHV-HD and other wildlife diseases are now recognized as ecological threats requiring state-funded surveillance systems.
-
Future litigation can compel the creation of national wildlife disease registries, analogous to human public health systems.
-
Practitioners should advise clients in infrastructure projects to conduct pre-construction wildlife mortality risk assessments in elephant corridors.
-
State Forest Departments must now integrate real-time GPS tracking data into conservation planning to meet NGT’s 'Mission Real-Time Monitoring' standard.
