The National Green Tribunal Southern Zone has delivered a pivotal ruling clarifying that environmental liability under the Polluter Pays Principle does not automatically transfer to a successor company that acquires an industrial unit after the alleged violations occurred. This judgment reinforces the principle that liability must attach to the actual polluter, not merely the current owner, absent clear evidence of knowledge, consent, or contractual assumption of liability.
Background & Facts
The Dispute
The appellant, M/s V.V. Titanium Pigment Pvt. Ltd., challenges an interim environmental compensation order of Rs. 1 crore imposed by the Tamil Nadu Pollution Control Board (TNPCB) dated 07.06.2024. The order was based on environmental violations allegedly observed during an inspection of the predecessor company, M/s. Kilburn Chemicals Limited, on 07.04.2011 - nearly three and a half years before the appellant took over the unit.
Key Facts
- M/s. Kilburn Chemicals Limited was established in 1999 and manufactured Titanium dioxide, Ferrous Sulphate, and Hydrochloric acid.
- On 29.07.2011, the appellant entered into a Memorandum of Understanding to take over M/s. Kilburn Chemicals Limited.
- The takeover was completed on 15.10.2011, and the unit was formally renamed M/s. V.V. Titanium Pigments Private Limited.
- The TNPCB issued an amendment to the Consent to Operate on 03.11.2011, transferring the consent from the erstwhile entity to the appellant, with no mention of pending violations or liabilities.
- On 07.04.2011, a joint inspection by NEERI, CPCB, and TNPCB officials observed: (i) acidic effluent stored in unlined underground tanks; (ii) non-operational effluent treatment facility; (iii) open storage of Ferrous Sulphate and raw ore.
- No show cause notice, inspection report, or enforcement action was issued to M/s. Kilburn Chemicals Limited following the 07.04.2011 inspection.
- The Central Pollution Control Board (CPCB) confirmed on 13.09.2023, via RTI response, that no records of the 07.04.2011 inspection existed in its files.
- The NEERI report dated May 2011 was prepared as part of a broader assessment of M/s. Sterlite Industries, with M/s. Kilburn Chemicals Limited mentioned only incidentally.

The Parties' Positions
Appellant: Argued that it was not the owner or operator on 07.04.2011; no notice was issued to the predecessor; no liability was crystallized at the time of takeover; the transfer of Consent to Operate implies no outstanding violations; the Polluter Pays Principle does not impose liability on successors without fault or agreement.
Respondent (TNPCB): Contended that the appellant, as the current operator of the unit, is liable for environmental degradation caused by the predecessor, citing the continuity of operations and the need for remediation under the Polluter Pays Principle.
Relief Sought
The appellant sought: (i) setting aside of the impugned order dated 07.06.2024; (ii) declaration that it is not liable for environmental compensation arising from pre-takeover violations; (iii) direction to TNPCB to identify and proceed against the actual polluter (M/s. Kilburn Chemicals Limited or its successors in interest); and (iv) removal of any adverse remarks from its compliance record.
The Legal Issue
The central question was whether a successor company can be held liable for environmental compensation based on violations committed by its predecessor, where no notice or enforcement action was initiated against the predecessor prior to the transfer of ownership, and no contractual assumption of liability exists.
Arguments Presented
For the Appellant
The appellant relied on the principle that liability under environmental law must be personal and tied to actual wrongdoing. It cited Polluter Pays Principle as a tool to hold the actual polluter accountable, not to impose vicarious liability on successors. It emphasized that the TNPCB had transferred the Consent to Operate without any reservation or notice of pending liability, indicating tacit acceptance of a clean transfer. The appellant also highlighted the absence of any show cause notice or sample collection under Section 21 of the Water Act, 1974, rendering the 2011 inspection legally invalid. It further relied on the CPCB’s RTI response confirming no records of the inspection, undermining the evidentiary basis of the order.
For the Respondent
The TNPCB argued that environmental degradation is a continuing harm and that the current operator, as the beneficiary of the industrial unit, must bear the cost of remediation. It contended that the Polluter Pays Principle requires the entity currently in control of the polluting activity to ensure cleanup, regardless of historical ownership. It cited Section 33A of the Water Act, 1974, and Section 5 of the Environment (Protection) Act, 1986, as empowering it to direct remediation from the current owner.
The Court's Analysis
The Tribunal undertook a rigorous analysis of the statutory framework and the jurisprudential foundation of the Polluter Pays Principle. It emphasized that the principle is not a tool for indiscriminate liability transfer but a mechanism to ensure that the party responsible for causing environmental harm bears the cost of remediation.
"The Polluter Pays Principle targets the actual polluter and does not automatically transfer liability to a successor merely because of a change in ownership. Liability must be established on the basis of fault, knowledge, or contractual assumption."
The Court noted that the inspection on 07.04.2011 was conducted on M/s. Kilburn Chemicals Limited, a distinct legal entity, and no notice was served under Section 21 of the Water Act, 1974. The failure to comply with mandatory procedural requirements under Section 21(3) - including serving notice, dividing samples, and obtaining signatures - rendered the inspection legally inadmissible as evidence.
The Tribunal further observed that the TNPCB’s own conduct - transferring the Consent to Operate without any conditions or reservations - indicated that it did not consider the unit to be in violation at the time of transfer. The absence of any prior enforcement action against the predecessor for over seven years further supported the conclusion that no liability had crystallized.
The Court rejected the argument that continuity of operations equates to continuity of liability. It held that the appellant had no control over the operations prior to 15.10.2011 and could not have prevented the alleged violations. The contamination observed in 2018 was attributed to waste dumped by the predecessor, and the Board’s own 2018 direction under Section 33A acknowledged this by directing reclamation - not compensation from the appellant for past acts.
The Tribunal also noted that the NEERI report was prepared for a broader assessment of Sterlite Industries and was not a formal enforcement document. The lack of any record in CPCB’s database further weakened the evidentiary foundation of the impugned order.
The Verdict
The appeal is allowed. The impugned order dated 07.06.2024 imposing an interim environmental compensation of Rs. 1 crore on the appellant is set aside. The Tamil Nadu Pollution Control Board is directed to identify and proceed against the actual polluter - M/s. Kilburn Chemicals Limited or its legal successors - for remediation of the contaminated site in accordance with the Polluter Pays Principle. The Board shall complete the identification process and initiate action within 12 weeks. The appellant shall not be held liable for any compensation arising from pre-15.10.2011 violations.
What This Means For Similar Cases
Successor Liability Requires Clear Fault or Agreement
- Practitioners must now argue that environmental liability cannot be imposed on a successor unless there is evidence of prior notice, contractual assumption, or active participation in the violation.
- Transfer of Consent to Operate without reservations is strong evidence that the regulator considered the unit compliant at the time of transfer.
Procedural Compliance Is Non-Negotiable in Environmental Sampling
- Any environmental sample collected without serving notice under Section 21(3) of the Water Act, 1974, is inadmissible in evidence.
- Failure to divide samples, seal containers, or obtain signatures invalidates the entire inspection process.
Polluter Pays Principle Is Not a Blanket Liability Transfer Mechanism
-
The principle does not permit regulators to bypass due process by shifting blame to current owners.
-
Remediation obligations may attach to current operators, but compensation for past violations must be levied only on the actual polluter.
-
Practitioners representing buyers in industrial acquisitions must insist on environmental audits and indemnity clauses in sale agreements.
-
Regulators must issue show cause notices to the actual violator before initiating enforcement against successors.
-
Environmental compensation orders based solely on historical inspections without procedural compliance or notice are vulnerable to challenge.
-
The burden of proving prior liability rests on the regulatory authority - not on the successor to disprove it.
