This judgment addresses two civil appeals filed under Section 22 of the National Green Tribunal Act, 2010, against orders passed by the National Green Tribunal (NGT) on 15 February 2022 and 16 September 2022.
A complaint was filed alleging that the appellant’s sugar mill was discharging untreated wastewater, contaminating groundwater in an area of about one and a half kilometres to a depth of 50 metres. The NGT found that the appellant had violated environmental norms through illegal disposal of untreated effluent, dilution at the outlet to conceal the real status, absence of a flow meter, lack of records for oil and grease, and the absence of an Effluent Treatment Plant (ETP) logbook.
NGT’s Directions:
Initially, the NGT directed a joint committee to assess the violations and determine compensation. This committee consisted of the Central Pollution Control Board (CPCB), Uttar Pradesh Pollution Control Board (UPPCB), and the District Magistrate of Muzaffarnagar.
Based on the committee’s supplementary report dated 10 August 2022, the NGT held that compensation of Rs. 18 crores (calculated at 2% of annual turnover) was justified. This amount was to be deposited with the District Magistrate of Muzaffarnagar within one month for environmental restoration.
Appellant’s Grievance: The appellant challenged the NGT’s orders, arguing that they were in complete violation of the principles of natural justice. Specifically, the appellant claimed they were not made a necessary party to the proceedings, were not issued notice, and were not given an opportunity to contest the joint committee’s reports or be heard before compensation was imposed.
Law Involved
National Green Tribunal Act, 2010 (NGT Act):
Section 22: Governs civil appeals against NGT orders.
Section 14: Deals with the NGT’s jurisdiction over “substantial questions relating to environment”.
Section 15: Addresses the NGT’s power to grant relief, compensation, and restitution for environmental damage.
Section 19: Pertains to the NGT’s procedure and powers, stating that the NGT is not bound by the Code of Civil Procedure, 1908, but must be guided by the principles of natural justice.
Water (Prevention and Control of Pollution) Act, 1974:
Sections 21 and 22: Concern the power to take samples of effluents and the procedure for analysis.
Section 24: Prohibits the release or disposal of polluting matter into streams or wells.
Section 43: Provides for punishment for contravention of Section 24.
Environment (Protection) Act, 1986: Sections 7, 8, 14A, 15, and 15A deal with the prevention, control, and abatement of environmental pollution, including penalties for contraventions.
Principles of Natural Justice: The core legal principle at stake was audi alteram partem, meaning “hear the other side” or the right to a fair hearing.
Reasoning
Appellant’s Contentions (Violation of Natural Justice):
The appellant asserted that NGT failed to appreciate that they were not a necessary party, were not issued notice, and were not given an opportunity of hearing regarding the impugned orders.
They argued that the joint committee’s reports suffered from factual mistakes and were based on erroneous data, but NGT accepted them without allowing the appellant to challenge them.
No opportunity was given to the appellant to contest the reports or present their case.
The environmental compensation was quantified without any adjudication or opportunity for hearing.
Respondent’s Defence (NGT’s Prerogative):
The respondents contended that the NGT took proper cognizance of the alarming pollution situation affecting a large population.
They argued that the joint committee carried out inspections scientifically, and its reports were rightly accepted.
The principles of natural justice, while important, should not be applied as a “straightjacket formula”.
Supreme Court’s Analysis:
The Court emphasised that the NGT, in exercising its judicial functions, must adhere to the principles of natural justice. While NGT is not strictly bound by the Code of Civil Procedure, it must be guided by these fundamental principles.
The principle of audi alteram partem is an “inalienable part” of natural justice and is essential for securing justice and preventing its miscarriage.
The Court noted that the NGT had outsourced the investigation to an administrative committee (the joint committee) and based its decisions solely on their recommendations without proper adjudication or giving the appellant a chance to respond.
It was highlighted that the NGT did not issue any notice to the appellant regarding the inspection, nor did it serve them a copy of the report, thus denying them the opportunity to contest the findings.
Expert committees assist in fact-finding, but their role cannot substitute the adjudicatory function of the NGT. The NGT cannot “abdicate its jurisdiction” by entrusting this function entirely to expert committees.
The Court referred to previous judgments, reinforcing that administrative authorities exercising quasi-judicial functions must record reasons for their decisions and ensure fairness and transparency. A quasi-judicial authority has a duty to disclose material relied upon at the stage of adjudication.
Holding
The Supreme Court allowed the civil appeals.
The impugned orders dated 15 February 2022 and 16 September 2022, passed by the NGT, were set aside.
The Court found that the NGT’s orders were in complete violation of the principles of natural justice, particularly audi alteram partem, as the appellant was denied an opportunity to be heard and contest the reports.
The matter was remitted back to the NGT to conduct a fresh hearing, ensuring that the appellant is given a proper opportunity to present their case and adhere to the statutory procedure laid down under the Water Act and the principles of natural justice.
The UPPCB remains empowered to carry out inspections and take remedial measures concerning the sugar mill’s effluents.
