Supreme Court Directs State To Pay Outstanding Compensation, Constitutes Audit Panel and Holds Polluters Liable Until Ecological Damage Is Reversed

A bench of Justices R. Mahadevan and J.B. Pardiwala heard appeals arising from SLPs challenging the Madras High Court’s common orders of February 2010 in litigation over decades‑long pollution of the Palar River by tanneries in erstwhile Vellore District. The appeals involved the Vellore District Environment Monitoring Committee and the All India Skin and Hide Tanners and Merchants Association (AISHTMA), and questions whether the Loss of Ecology (Prevention & Payment of Compensation) Authority (LoEA) could assess compensation, and whether polluters remained liable after 31.12.1998.

The Court allowed in part and modified the High Court’s orders. It upheld the LoEA’s 24.08.2009 award in respect of left‑out claimants, held that polluters’ liability continued until ecological harm was reversed, and directed the State to pay outstanding compensation within six weeks and to recover the amounts from identified polluters by revenue recovery or other lawful means. The Court ordered constitution of a high‑level audit and implementation committee (to be chaired by a retired High Court judge with State and Central officials, experts and community representatives) to assess remaining claims, frame and supervise a scheme for reversal of ecological damage, ensure functioning of CETPs/IETPs and STPs, and recommend further measures including real‑time monitoring, quarterly inspections and strengthened enforcement. The Court stressed that the State must implement reversal schemes and that polluters could not avoid continuing liability by earlier deposits.

The Court, in its reasoning, observed: “Consequently the polluting industries are thus ‘absolutely liable to compensate for the harm caused by them to villagers in the affected area, to the soil and to the underground water and hence, they are bound to take all necessary measures to remove sludge and other pollutants lying in the affected areas’. The ‘Polluter Pays Principle’ as interpreted by this Court means that the absolute liability for harm to the environment extends not only to compensate the victims of pollution but also the cost of restoring the environmental degradation. Remediation of the damaged environment is part of the process of ‘Sustainable Development’ and as such the polluter is liable to pay the cost to the individual sufferers as well as the cost of reversing the damaged ecology.”

The judgment reiterated the Court’s earlier admonition that “this Court shall not be a mute spectator to the environmental consequences” of unchecked industrial pollution and recorded the LoEA’s view that “the liability of the polluting industries continued beyond 31.12.1998 until the damage caused to the ecology and environment by pollution is reversed.”

Background The dispute arose from long‑running pollution of the Palar River and adjoining lands by tannery effluents, municipal sewage and solid waste in Vellore District. Following this Court’s landmark Vellore Citizens Welfare Forum directions (1996), the Central Government constituted the LoEA (1996) which, by award dated 07.03.2001, identified 29,193 affected individuals and assessed compensation (1991–1998) while declaring that industry liability continued until damage was reversed. Subsequent proceedings produced a further LoEA award dated 24.08.2009 addressing left‑out claims and an LoEA order of 05.05.2009 assessing liability beyond 1998; the latter was quashed by the High Court. The High Court by common orders in February 2010 dismissed the public interest litigation filed by the Vellore District Environment Monitoring Committee and disposed other challenges; AISHTMA’s challenge to the LoEA award was also dismissed.

Before the Supreme Court, the monitoring committee argued that compensation remained unpaid to many affected families, remedial schemes were not implemented and pollution continued; it sought directions for payment, closure of non‑compliant units and fresh assessment beyond 1998. AISHTMA contended it and members had paid amounts determined by LoEA and invested heavily in CETP/IETP and ZLD systems; it challenged the LoEA’s 2009 exercise as beyond jurisdiction and procedurally flawed. CPCB and TNPCB reports filed in 2024 showed upgraded ZLD infrastructure but continuing localized exceedances in outfalls, groundwater and substantial sewage and municipal solid waste problems. The Supreme Court found that some payments and upgradation had occurred but that ZLD and sewage treatment were not fully effective district‑wide, and that governmental inaction on reversal schemes and persistent pollution justified authoritative directions.
