When the National Green Tribunal issues notice on a case filed against your factory, you defend it with paper, not protests. Appear on the first date, read the application and its annexures line by line, file a reply on affidavit that answers every allegation with your consents, monitoring records and lab reports, and get ready for a site inspection by a joint committee. Raise legal objections such as delay or lack of jurisdiction where they genuinely apply, but fix any real gap in compliance at the same time. The tribunal rewards units that can show they comply today.

Short answer: To defend an NGT case against your industry, appear on the first date, file a point-by-point reply on affidavit backed by valid consents, monitoring data and lab reports, prepare properly for the joint committee inspection, object to wrong findings in its report, and correct any genuine shortfall before the final hearing.

This guide is for factory owners, plant heads and company secretaries who have just received a notice from the NGT. It covers the first order, the objections worth taking, the documents that carry weight, the inspection, and how to keep environmental compensation within reason. To see the case from the applicant's side, read our guide on how a case is filed in the NGT. Appeals your own unit files against a board order follow a different route, explained on our page on appealing a pollution board's order.

हिंदी में सारांश

अगर आपकी फैक्ट्री या उद्योग के खिलाफ एनजीटी में केस दर्ज हुआ है और नोटिस आया है, तो उसे नज़रअंदाज़ न करें। पहली तारीख पर पेश हों, आवेदन और उसके सभी दस्तावेज़ ध्यान से पढ़ें, और हर आरोप का जवाब शपथपत्र पर दें। जवाब के साथ सीटीई, सीटीओ, खतरनाक कचरे का प्राधिकरण, मॉनिटरिंग रिकॉर्ड, ईटीपी लॉगबुक और प्रयोगशाला रिपोर्ट लगाएँ। एनजीटी अक्सर संयुक्त समिति बनाकर निरीक्षण कराता है, इसलिए निरीक्षण की तैयारी करें और रिपोर्ट गलत हो तो आपत्ति दाखिल करें। देरी या क्षेत्राधिकार जैसी कानूनी आपत्तियाँ तभी उठाएँ जब वे सच में बनती हों। सबसे मज़बूत बचाव यह है कि सुनवाई से पहले आपकी इकाई वास्तव में नियमों का पालन कर रही हो।

In short

The essentials

Never miss the first date

An absent unit can face directions without being heard.

Answer every allegation

A skipped point reads as an admission.

Consents are your base

Valid CTE, CTO and waste authorisations answer half the case before it starts.

The inspection decides a lot

The committee report often outweighs both affidavits.

Compensation can be contested

Category, days of violation and unit size can all be challenged.

Fix as you fight

Real compliance shown on record is the defence that works most often.

First things first

I've received an NGT notice against my factory. What should I do first?

Note the date of hearing and make sure someone appears for the unit on that date, in person or through an advocate, physically or by video conference. Units that treat the notice as a formality, or send a letter instead of appearing, often find a committee already constituted or interim directions passed without their side being heard.

Next, get the complete paper book. The notice often carries only the first order. Ask the applicant for the full application with every annexure, or inspect the file. You cannot reply to a photograph you have not seen or a lab report whose sampling point you do not know.

Then read the first order carefully. If it has asked the State Board and the District Magistrate for a factual report, you know an inspection is coming within weeks. If it has directed the board to take action in accordance with law, the board may visit even before your reply is ready. Plan from that order, not from the applicant's adjectives.

Reading the first order

What the first NGT order usually means for your unit

First orders tend to follow a few patterns, each needing a different response.

What the order saysWhat it means in practiceWhat you should do now
Notice issued to respondents, reply in a set timeThe tribunal wants both sides before it decides anythingCollect documents, start the reply, check limitation and jurisdiction
Joint committee of CPCB, State Board and DM constitutedA site inspection and factual report will come before any hearing on meritsPrepare the plant, records and staff for the visit; nominate a responsible officer
State Board directed to inspect and take actionThe board may issue a show-cause or closure direction on its own findingsGet ahead of the board: compliance check, sampling by an accredited lab, written explanation ready
Interim direction to stop an activityRare at the first hearing, but seriousComply, then apply for modification with evidence; read our note on interim relief and stays in the NGT
Application disposed of with directions to the authoritiesThe NGT has passed the matter to the board or DM to decideEngage with the board's proceedings; the next fight is at that level

The last row surprises people. Many applications are closed early with a direction to the board or the DM to act in accordance with law. For an industry that is neither a win nor a loss: the dispute moves to the board, where your reply to its show-cause notice now matters most.

Legal objections

Can the case be thrown out on a technical ground?

Sometimes, but do not build your defence on it. The NGT is not bound by the Code of Civil Procedure (section 19 of the NGT Act) and is reluctant to dismiss a case on a technicality where the pollution appears to be real. Objections work when they are true and obvious, and when you also answer the facts.

The objection that succeeds most often is limitation. An application under section 14 must be filed within six months from the date the cause of action first arose, with up to 60 more days for sufficient cause; a compensation claim under section 15 has five years. If the applicant is challenging something done years ago, such as the grant of your consent, the objection has weight. If the complaint is about discharge that continues today, expect the applicant to argue a continuing wrong, explained in our guide on continuing cause of action in NGT cases.

Jurisdiction is the next one. The NGT hears disputes raising a substantial environmental question under the seven Acts in Schedule I. A quarrel about a boundary wall, a lease or a labour issue does not become an environmental case because the word pollution appears in it, and a pure Wild Life (Protection) Act or Indian Forest Act matter falls outside Schedule I. If the case is really a forum question, our guide on High Court writ or NGT case explains how the two divide the work.

Two more objections fit some cases: the same complaint has already been decided and not disclosed, or the applicant has suppressed material facts, such as a recent board inspection that found the unit compliant. Both can support a request for compensatory costs under section 23, which the tribunal can award where a claim is false or vexatious.

Your reply

How should the reply to an NGT application be written?

Write it as a factual record, not a rebuttal speech. The reply, usually on affidavit by an authorised officer, should open with the unit's basic facts: what it makes, its CPCB category, its consent history, its pollution control equipment and its monitoring. A bench member should understand the plant in two minutes.

Then go through the application paragraph by paragraph. For each allegation say whether it is admitted, denied or not known, and why, with the annexure number of the document that proves your answer. A general denial at the end (all allegations not specifically admitted are denied) does not protect you if you have skipped something specific. If the applicant says your ETP has been bypassed through a pipe to the drain, answer that exact point: there is no such pipe, here is the site plan, here is the board's last inspection report, here are photographs taken on a stated date.

Keep the tone even. Calling the case blackmail without proof, or warning of job losses if the unit closes, reads badly; the tribunal gives the jobs argument little weight against evidence of pollution. Investment in treatment, upgrades already ordered and monitoring results within limits carry far more.

When Advocate B.K. Singh drafts a reply for an industrial unit, he starts by listing every factual claim in the application on one sheet and marking the document that answers it. Gaps in that sheet show, before the hearing, exactly where the unit is exposed and what has to be fixed or explained.

Evidence

Documents to collect before you file the reply

Arrange these in date order; explain gaps rather than hide them.

  • Groundwater NOC or proof of exemption

Operations

  • ETP, STP and air pollution control equipment logbooks
  • Energy meter readings for the ETP and APCD (they show whether equipment actually ran)

  • Photographs and video of the plant with dates
Step by step

Defending an NGT case, from notice to final order

1

Record the dates

Note the hearing date, any reply deadline and the date the notice reached you. Make sure management, not only the plant manager, has them.

2

Get the full application

Check which sections of the NGT Act are invoked, who else is a respondent and what reliefs are sought.

3

Do an honest compliance check

Before writing a word, have someone independent walk the plant against the consent conditions.

4

Appear on the first date

Through an advocate or an authorised representative. Ask for time to reply if needed.

5

File the reply on affidavit

Answer each paragraph, attach documents, state preliminary objections only where they genuinely apply, and serve copies on all parties.

6

Prepare for the inspection

Keep records at the plant, have a senior person present, run equipment normally, and ask for a copy of the sampling memo or inspection note on the spot.

7

Respond to the committee report

Read it the day it is uploaded. File objections pointing out factual errors, wrong sampling points or wrong standards, with supporting documents.

8

Argue the final hearing

Focus on present compliance, the scale of any past lapse, and why any compensation sought is excessive. Then comply with the order on time.

Site inspection

How do I prepare for the joint committee inspection?

Prepare as if the report will decide the case, because it often does. A joint committee, typically from the CPCB, the State Board and the District Magistrate's office, visits the unit and its surroundings, takes samples, looks at records and files a factual report. It is far easier to shape that report by preparing well than to challenge it afterwards.

Run the plant normally on the day. A factory that is suddenly silent, an ETP tank freshly painted but bone dry, or six months of logbook entries in one hand and one ink tells its own story. Keep logbooks, consents, lab reports and manifests in one room, and have a person who actually knows the process walk the committee through it.

Ask where samples are being taken and request that a split sample be given to you, so your own accredited laboratory can test it. Note the time, location and weather, and photograph the sampling. If the committee's note records something wrong, such as the ETP outlet being sampled at the inlet, put your objection in writing that same day. Keep the tone cooperative. A unit that obstructs or argues on site gets that recorded.

After the report

What if the joint committee report is wrong?

File objections, quickly and specifically. The tribunal usually gives parties a short time to respond. Point out errors one by one: a sample tested against the wrong standard, a result attributed to your outfall when the drain carries effluent from several units, a finding of no consent when your renewal application was pending with the board, or photographs of a neighbouring plant. Attach your split-sample result and documents. Our guide on objecting to a joint committee report goes through this stage in detail.

Where the dispute is technical, an affidavit from your own environmental engineer or chemist explaining why a result cannot be right is often more persuasive than a lawyer's argument. When to bring in such evidence, and from whom, is covered in our note on expert and laboratory evidence in the NGT.

Do not object to everything. If the report correctly records that the ETP was not running or that sludge was stored in the open, accept it, explain what has been done since and show proof. Credibility on the points you contest depends on candour about the points you cannot.

Money

Can I contest the environmental compensation the NGT may impose?

Yes, on the figures as much as on liability. Where a violation is found, the tribunal often directs the CPCB or the State Board to calculate environmental compensation. The boards use a formula-based CPCB methodology that multiplies factors such as a pollution index for the industry category, the number of days of violation, a scale factor for the unit's size and a location factor. Each of those factors can be wrong.

Check the category first. A unit treated as red when it is properly orange will see its figure jump. Then check the days of violation: boards sometimes count from the date of the complaint or the last valid consent to the date of the inspection, ignoring the period in which the unit had a renewal application pending, was shut, or had already corrected the defect. A short, numbered note pointing out such errors, with documents, is the right response.

Where the board itself demands compensation, our pages on replying to an environmental compensation demand and on challenging or claiming environmental compensation explain that route.

Matching the evidence

Common allegations against factories and the evidence that answers them

Running without consentValid CTO, or renewal filed in time with fee receipt and board acknowledgementExpanded capacity or new products not covered by the consent
Untreated effluent into drain or riverETP logbooks, energy readings, outlet analysis by accredited lab, board sample resultsHidden bypass lines, overflow during rain, mismatch between water use and ETP capacity
Smoke, dust or odourStack monitoring, APCD maintenance records, fuel records, ambient monitoringFugitive emissions from loading, open storage and unpaved yards
Illegal groundwater useCGWA or state NOC, flow meter readings, or proof of exemptionExtra borewells not shown in the NOC

Noise at nightNoise monitoring reports, shift records, acoustic enclosures for DG setsNight loading and unloading by contractors
The strongest defence

Why fixing the problem during the case usually helps more than winning the argument

Because the tribunal's question is less about the past than about what happens next. Section 20 of the NGT Act requires it to apply the precautionary and polluter pays principles, and since Vellore Citizens' Welfare Forum v Union of India (1996) the practical burden sits on the unit to show its operations are safe. A unit that has upgraded its ETP, installed monitoring and files regular data tends to see monitoring directions and a measured compensation figure. One that disputes everything and changes nothing risks closure.

Document every step taken after the notice: purchase orders, commissioning reports, fresh consent or authorisation where needed, and fresh sampling by an accredited lab. If the board must inspect and certify, apply in writing and put that application on the NGT record. Our page on environmental compliance audits describes what an independent audit checks.

Fixing the problem is not an admission of liability for everything alleged. Your reply can say both things: the allegations of continuous untreated discharge are denied for the reasons given, and, without prejudice, the unit has commissioned a tertiary treatment stage to remove any doubt.

What goes wrong

Mistakes industries make when defending NGT cases

  • Not appearing. The tribunal is entitled to proceed, and the committee will visit anyway.
  • Leaving it to the plant manager. Decisions on compliance spending, closure risk and compensation are board-level decisions and should be taken early.
  • Relying only on the consent certificate. A valid CTO does not prove that its conditions are being followed on the ground.
  • Filing a reply without documents. Bare denials, however firm, rarely survive a committee report.
  • Cleaning up only for inspection day. Logbooks, energy meters and neighbours' photographs tell the committee what normal days look like.
  • Ignoring the board while fighting the NGT case. A parallel show-cause notice from the State Board must be answered; see our page on replying to pollution control board notices.
  • Missing the deadline for objections. An unchallenged report is usually accepted as it stands.
Illustration

A foundry, a letter petition and a committee report

Here's a made-up example. A small iron foundry on the edge of an industrial area in western Uttar Pradesh receives notice from the NGT Principal Bench. Residents of a nearby village have written to the tribunal complaining of black smoke from the cupola furnace and slag dumped on common land. The tribunal registers the letter as an application, issues notice and forms a joint committee of the CPCB, UPPCB and the District Magistrate.

The owner's first instinct is to blame a rival. Instead, the foundry checks its own position. The consent is valid, but the bag filter has been bypassed for weeks because of a torn bag, and slag has been sent to a contractor who dumped it nearby. The foundry replaces the bags, gets stack monitoring done by an accredited lab, retrieves the slag through the contractor, and documents all of it.

The committee finds emissions within limits but records the slag dump and, from the logbook, the earlier bypass. The report suggests compensation calculated for 180 days. The foundry objects with dated purchase records showing the bypass lasted about five weeks and the slag was cleared before the visit. The tribunal accepts the shorter period, directs deposit of compensation with the board and orders quarterly monitoring. The unit keeps running. Had it denied everything, the report alone would have decided the case.

After the order

What happens after the NGT decides the case?

Comply on time, and file proof of compliance where the order asks for it. If the tribunal directs deposit of compensation, installation of equipment or monitoring by the board, missing the deadline invites an execution application, and section 26 makes wilful non-compliance punishable with imprisonment, heavy fines and daily fines. Our guide on execution applications in the NGT shows how applicants enforce orders, which is useful to understand from the other side.

If you believe the order is legally wrong, an appeal lies to the Supreme Court under section 22 within 90 days of communication, on a question of law, with a possible extra 90 days for sufficient cause. An appeal is not a re-hearing of the facts. Where the order contains an error apparent on the record, such as a document on file that was overlooked, a review before the NGT may be the faster option; see review applications against NGT orders. Costs and appeal timelines are set out in our guide on NGT case costs and appeals, and the stages in between in what happens in an NGT case after filing.

FAQs

Frequently Asked Questions

Can my factory ignore an NGT notice if we have a valid consent?

No. A valid consent is evidence in your favour, but the tribunal can still form a committee and pass directions if no one appears for the unit.

Is a lawyer necessary to defend an NGT case?

A party may appear in person, and a company can act through an authorised officer. Most industries engage an advocate because the reply and compensation arguments are technical.

How long do I get to file a reply in the NGT?

The order issuing notice usually fixes a time. If you need more, ask for it on the first date with a reason, and do not wait for the last day to start collecting documents.

Who inspects my factory after an NGT notice?

Usually a joint committee of the CPCB, the State Pollution Control Board and the District Magistrate's office, though other bodies can be added depending on the complaint.

Can I get my own samples tested during the inspection?

Ask the committee for a split sample at the time of sampling and have it tested by an accredited laboratory.

Can the NGT close my factory?

It can direct closure for serious, continuing violations. Closure is less likely where the unit shows it has corrected the problem.

How is environmental compensation calculated against an industry?

Boards use a CPCB formula that multiplies factors such as an industry category index, days of violation, unit size and location. You can contest the category, the period and the size used.

The complaint was filed by a competitor. Does that help my defence?

Motive alone does not defeat a case if pollution is shown. If the facts are false, ask for compensatory costs under section 23.

What if the NGT passes an order against us?

Comply on time. If there is a legal error, appeal to the Supreme Court within 90 days of communication.

Can we settle an NGT case with the residents?

A private settlement does not bind the tribunal, which decides on environmental compliance. What helps is fixing the cause of the complaint and placing proof of it on record.
