The National Green Tribunal Southern Zone has affirmed that a final closure order issued under environmental statutes supersedes even a valid Consent to Operate, establishing a critical precedent for enforcement against repeat polluters. The judgment underscores that regulatory compliance is not a one-time formality but an ongoing obligation, and failure to meet conditions renders any statutory approval ineffective.
Background & Facts
The Dispute
The Applicants, M. Mani and R. Poovaragavan, are local agriculturists and landowners in P.N. Patti Village, Mettur Taluk, Salem District, Tamil Nadu. They filed the Original Application before the National Green Tribunal (NGT) seeking permanent closure and relocation of M/s. Nutri Flavours Private Limited, a red-category industrial unit operating on Survey Numbers 146/1B2 and 146/3. The Applicants allege that the land, classified as ayacut (irrigated agricultural) land in revenue records, was illegally converted for industrial use without proper authorization under the Tamil Nadu Town and Country Planning Act, 1971. The unit, established in 2023, manufactures hydrolysed chicken powder, liquid derivatives, and rice/soya products.
Key Facts
- The industrial unit occupies approximately 2.11 acres of land in S.F. Nos. 146/1B2 and 146/3.
- The land was classified as "Punjai" (dry land) in revenue records (Online Patta No. 4013), and a No Objection Certificate (NOC) for land use conversion was issued by the Joint Director of Agriculture on 26.07.2018.
- The unit obtained Consent to Establish (CTE) from TNPCB on 12.08.2015 (valid until 11.08.2017), revised CTE on 04.01.2020 (valid until 31.03.2024), and a renewed Consent to Operate (CTO) on 07.01.2023 (valid until 31.03.2027).
- The unit commenced production in 2023.
- Multiple public complaints were received regarding odour nuisance, air pollution, and discharge of untreated effluents.
- TNPCB inspections on 03.01.2024 and 08.04.2024 revealed non-operation of the Effluent Treatment Plant (ETP) and improper effluent disposal.
- Show Cause Notices were issued on 03.01.2024 and 08.04.2024, followed by a personal hearing on 15.04.2024.
- Closure directions were issued under Section 33A of the Water (Prevention and Control of Pollution) Act, 1974 and Section 31A of the Air (Prevention and Control of Pollution) Act, 1981 on 09.05.2024, with power disconnected on 10.05.2024.
- Power was temporarily restored on 24.06.2024 (for 3 months), 12.11.2024 (for 2 months), and 29.04.2025 (for 6 months, until 28.10.2025), subject to strict conditions including ETP revamp, installation of VOC sensors, and implementation of NEERI-recommended odour control measures.
- Inspections on 24.02.2025 and 11.09.2025 found incomplete compliance: continuous air monitoring was not installed, NEERI reports were not submitted, and VOC sensors were not operational.
- Power was permanently disconnected on 29.10.2025 after expiry of the last temporary revocation period.
- The unit claims to have spent Rs. 100 lakhs on ETP improvements and green belt development.

The Parties' Positions
Applicants: Argued that the unit operates illegally on agricultural land, causes persistent pollution, and has repeatedly violated environmental norms despite regulatory interventions. They sought permanent closure and relocation.
Respondents (TNPCB, Planning Authorities, Unit): TNPCB submitted that it had taken multiple regulatory actions, issued closure orders, and granted conditional revocations. The unit claimed full compliance with statutory approvals and investments in pollution control. The Town and Country Planning Department maintained that land conversion was lawful based on NOC and revenue classification.
Relief Sought
The Applicants sought:
- Permanent closure and relocation of the industrial unit.
- Enforcement of environmental compliance.
- Restoration of agricultural land use.
- Compensation for loss of livelihood and environmental degradation.
The Legal Issue
The central question was whether a final closure order issued under Section 33A of the Water Act, 1974 and Section 31A of the Air Act, 1981 remains enforceable despite the continued validity of a Consent to Operate, and whether the National Green Tribunal has jurisdiction to adjudicate disputes concerning land use conversion under state planning laws.
Arguments Presented
For the Appellant/Petitioner
The Applicants argued that the unit’s repeated violations - particularly non-operation of the ETP and persistent odour emissions - constitute a continuous threat to public health and ecological integrity. They relied on M.C. Mehta v. Union of India to assert that the precautionary principle and polluter pays principle demand strict enforcement. They contended that the issuance of a CTO does not immunize an industry from closure for non-compliance, and that the Tribunal must act to protect the environment when regulatory agencies fail to enforce effectively.
For the Respondent/State
The TNPCB and other respondents argued that they had acted diligently: multiple inspections, show cause notices, temporary revocations, and conditions were imposed to allow compliance. They emphasized that the closure order was not challenged in appeal and had attained finality. The Planning Authorities maintained that land conversion was lawful under the Tamil Nadu Town and Country Planning Act, 1971, based on the NOC and revenue records, and that such matters fall outside the NGT’s jurisdiction.
The Court's Analysis
The Tribunal conducted a meticulous review of the inspection reports, compliance orders, and correspondence between the unit and TNPCB. It noted that the closure order dated 09.05.2024 was not appealed within the statutory period, thereby acquiring finality under the principle of res judicata in administrative law. The Tribunal held that the validity of the Consent to Operate (CTO) does not override a final closure order, as the latter is a coercive enforcement mechanism under specific statutory provisions.
"The subsistence of Consent to Operate granted up to 31.03.2027 does not confer any right upon the 10th Respondent unit to resume operations in the face of an operative closure order. The consent, though not formally revoked, stands eclipsed by the closure directions, and so long as the same remains in force, the unit is legally restrained from operating."
The Tribunal further observed that while the unit had undertaken some remedial measures - including ETP revamp and installation of scrubbers - it had failed to implement critical conditions such as continuous air quality monitoring, online VOC sensors, and submission of NEERI reports. The repeated extensions of temporary revocation were not rewards but conditional suspensions, and the unit’s failure to meet them justified permanent closure.
Regarding land use conversion, the Tribunal explicitly declined to adjudicate, noting that such disputes fall under the exclusive domain of the Tamil Nadu Town and Country Planning Act, 1971, and revenue authorities. The NGT’s mandate under the National Green Tribunal Act, 2010, is confined to environmental violations and enforcement of environmental statutes, not land classification or planning permissions.
The Tribunal emphasized that environmental regulation is not a series of administrative concessions but a system of enforceable obligations. The unit’s expenditure of Rs. 100 lakhs, while noted, could not substitute for statutory compliance.
The Verdict
The Applicants succeeded in their primary prayer. The Tribunal directed that the 10th Respondent unit shall remain under permanent closure and shall not resume operations unless the Tamil Nadu Pollution Control Board is fully satisfied that all deficiencies have been rectified and complete compliance with all statutory conditions has been achieved. Upon any future recommissioning, the unit must strictly implement all NEERI recommendations, including Zero Liquid Discharge (ZLD), and submit a comprehensive compliance report for verification. The TNPCB is directed to take immediate action under law if any future violation or recurrence of odour nuisance occurs. The closure order dated 09.05.2024 remains in full force.
What This Means For Similar Cases
Closure Orders Trump Valid Consents
- Practitioners must advise clients that even a valid Consent to Operate is subordinate to a final closure order under Sections 33A and 31A.
- Industries cannot rely on the expiry date of a CTO to justify resumption of operations if a closure order is active.
- Regulatory agencies must be proactive in enforcing closure orders, and failure to do so may invite judicial intervention.
Compliance Must Be Complete, Not Partial
- Temporary relief granted for compliance is conditional and revocable.
- Partial implementation of remedial measures (e.g., installing scrubbers but not VOC sensors) is insufficient.
- Documentation and submission of third-party reports (e.g., NEERI) are mandatory conditions, not optional.
NGT Jurisdiction Is Limited to Environmental Violations
- Disputes over land classification, conversion, or planning permissions must be challenged before planning authorities or High Courts under the respective state Acts.
- Environmental tribunals will not entertain challenges to revenue records or planning approvals, even if they underlie pollution issues.
- Petitioners must bifurcate claims: environmental violations before NGT, land use disputes before civil or planning courts.
