How to Challenge an Environmental Clearance in the NGT

An environmental clearance (EC) granted by the Ministry of Environment or a State Environment Impact Assessment Authority (SEIAA) can be challenged by appeal to the National Green Tribunal under section 16 of the NGT Act. The appeal must be filed within 30 days of the date the EC is communicated, and the tribunal can allow up to 60 more days if you show sufficient cause. Any person aggrieved can appeal, including villagers, farmers, fishing families, RWAs and local groups. What wins these appeals is rarely general opposition to the project. It is a specific flaw in how the clearance was granted.

This page is for people who have just learnt that a mine, plant, highway or large building next to them has been cleared, and for project owners whose clearance is under attack. It explains the appeal route, the deadline that trips most people up, the grounds the tribunal takes seriously, and how we build an appeal. For the wider picture on the clearance process itself, see our page on environmental clearance under the EIA Notification.

If the problem is a project that never took an EC, or one that ignores the conditions in its EC, that is a different case with a longer time limit. We cover it on our page on projects running without EC or breaking EC conditions.

The essentials

Can an environmental clearance be challenged, and where do you go?

Yes. Section 16 of the National Green Tribunal Act, 2010 gives any person aggrieved a right of appeal to the NGT against an order granting environmental clearance, and the project proponent gets the same right against an order refusing it. This covers category A clearances granted by the Ministry of Environment, Forest and Climate Change (MoEFCC) on the advice of its Expert Appraisal Committee, and category B clearances granted by the SEIAA on the advice of the State Expert Appraisal Committee.

The appeal goes to the NGT bench that covers the state where the project is located: the Principal Bench in New Delhi, or the zonal benches at Bhopal, Pune, Kolkata and Chennai. Our page on which NGT bench hears your state sets out the split. You can file through the NGT's e-filing system, and hearings often take place by video conference, so distance from the bench is less of a barrier than it used to be.

Do not start in the High Court. A writ petition is technically possible, but High Courts usually send EC disputes to the NGT because the NGT Act provides a specific appeal. Losing three months in the wrong forum can cost you the appeal altogether.

Which remedy fits which situation

People often call every project dispute an EC challenge. The route and the time limit depend on what exactly went wrong.

Some cases involve more than one of these: a mine with a doubtful EC that also digs beyond its approved area can face both an appeal and an original application. The shorter deadline usually decides the sequence.

How long do you have to appeal against an environmental clearance?

Thirty days from the date the order is communicated. The NGT can allow a further period of up to 60 days if you show sufficient cause for the delay. After 90 days in total, the tribunal has no power to entertain the appeal, however strong it is.

The hard part is working out when the EC was communicated to a person who was never sent a copy. The EIA Notification requires the clearance to be put in the public domain in several ways: it is uploaded on the website of the regulator, the proponent must advertise it in local newspapers, and copies go to local bodies and offices. The NGT has generally counted time from the date the clearance was made public in the manner the notification requires. Exactly which date counts has been argued in many cases, so the safe course is to assume the earliest plausible date and file well within 30 days of it.

If you are already past 30 days, file a delay condonation application with the appeal and explain the delay honestly and in detail: when you learnt of the EC, what you did each week after that, and why it took time to get the documents. Vague reasons like "we were collecting information" rarely satisfy the bench. Our guide on NGT time limits and late cases explains how delay is argued.

Who is allowed to challenge an EC?

Section 16 and section 18 of the NGT Act allow any person aggrieved to appeal, and section 18 expressly includes representative bodies and organisations. In practice this means people whose land, water, air, livelihood or surroundings will be affected: residents of the villages around a mine, farmers downstream of a plant, fishing families near a port, an RWA next to a large construction project, or a local group that has worked on the issue.

The tribunal takes a broad view of who is aggrieved in environmental matters, but it is not unlimited. Appeals filed by a business rival under the cover of environmental concern, or by someone with no connection to the area and no track record on the issue, get closer scrutiny. Section 23 allows the NGT to award compensatory costs against a party whose case is false or vexatious, and it has used that power.

An appeal by several residents living close to the site reads better than one by a lone individual far away. Attach any panchayat or RWA resolution.

What grounds actually succeed in an EC appeal?

The NGT does not sit as a second appraisal committee deciding whether it likes the project. It asks whether the clearance was granted lawfully and on a proper consideration of the facts. The grounds that carry weight are defects in that process.

The first group is the public consultation. A public hearing held far from the affected villages, with inadequate notice, without the draft EIA and summary being available in the local language, or with minutes that leave out what people actually said, can vitiate the clearance. Our guide on objections at an EIA public hearing explains how this record is made and why it matters later.

The second group is the EIA report itself. Baseline data copied from another project, a forest or water body left off the map, wrong distances to villages or protected areas, or cumulative impacts of nearby units ignored are common. The EIA Notification says that deliberate concealment or false or misleading material information makes an application liable to rejection and a clearance granted on that basis liable to cancellation. See our guide on mistakes in an EIA report for how these are proved.

The third group is the appraisal. Wrongly treating a project as category B2 to skip the public hearing, splitting one project into smaller pieces to stay under a threshold, approving without the terms of reference studies being done, or committee minutes that simply repeat the proponent's claims without dealing with the objections on record, are all grounds the tribunal examines closely.

Arguments that usually do not work on their own

These points may be true and may matter to you, but they rarely win an EC appeal without a concrete legal defect behind them.

• We simply do not want the project here. Opposition without a defect in the EIA, hearing or appraisal is not a ground.
• Land compensation is too low. That is a land acquisition or contract issue, not an environmental one, and belongs in a different forum.
• The company has a bad reputation. Past violations elsewhere help only if they bear on this project's compliance or the honesty of its data.
• Fears without any data. Saying dust will cause cancer is weaker than showing the EIA ignored a school 400 metres downwind.
• Points raised for the first time with no basis. If something could have been raised at the public hearing, explain why it was not.

How to file an appeal against an EC: the practical plan

This is the sequence we follow. The first three steps usually happen in the same week because of the deadline.

Section 18(3) says the NGT will try to decide appeals within six months of filing. In practice many EC appeals take longer, especially when a committee is appointed, so plan for a year rather than six months.

Documents that make or break an EC appeal

What can the NGT do with a flawed environmental clearance?

The tribunal has a range of options. It can dismiss the appeal, uphold the EC but add conditions, suspend the EC while the defect is cured, send the matter back to the appraisal committee for fresh consideration, or set the clearance aside. Remand is a frequent outcome where the defect lies in the appraisal: the committee is told to look again at specific issues, sometimes after fresh studies or a fresh public hearing.

Outright quashing is more likely where the defect goes to the root, such as a public hearing that was never properly held or material facts that were concealed. Where the project is already built and running, the tribunal applies the polluter pays and precautionary principles under section 20 and may impose environmental compensation and remedial conditions rather than order demolition.

Filing an appeal does not stop the project by itself. Unless the NGT passes an interim order, the proponent can proceed at its own risk. Our guide on interim relief and stay in the NGT explains what the bench looks for before stopping work. If you lose, section 22 allows an appeal to the Supreme Court within 90 days on a question of law.

If your EC has been challenged or refused

A proponent whose clearance is under appeal is a necessary party and must defend its own case; the regulator's reply will defend the process but not your data. Your consultant should be ready to explain every baseline figure, map and modelling assumption the appellants attack, and you should show what you did with the objections raised at the public hearing.

If the EC was refused or granted with conditions that are technically impossible, the same section 16 appeal is available to you within 30 days. Before appealing, consider whether a fresh application with corrected studies would be faster. An appeal makes sense where the refusal rests on a legal error or on facts the committee plainly misread.

Do not treat a pending appeal as permission to rush construction. Work done after an appeal is filed is the first thing a bench looks at when it considers interim relief, and it weighs heavily if the clearance is later set aside.

What we do at each stage of an EC challenge

• First review within days. We read the EC, fix the limitation date and tell you plainly whether there is a real ground. When Advocate B.K. Singh reviews an EC file, he starts with the committee minutes, because that is where a mechanical appraisal usually shows itself.
• Building the record. We collect the EIA, hearing proceedings and minutes, draft RTI applications, and work with you on site evidence and maps.
• Drafting and filing. We draft the memo of appeal, the delay application if needed and the interim prayer, and file before the correct bench.
• Hearings and committees. We argue the appeal, respond to replies, and file objections to any committee report the tribunal calls for.
• After the order. We advise on compliance, on a Supreme Court appeal under section 22, or on an execution application if directions are ignored.
• For proponents. We defend clearances under challenge and appeal against refusals, working with your EIA consultant on the technical record.

Mistakes that sink EC appeals

The most common mistake is waiting. People spend weeks writing letters to the collector and the minister, hoping the problem goes away, and by the time they reach a lawyer the 90-day outer limit has passed. Letters do not stop time running. If you want to write to the authorities, do it alongside the appeal, not instead of it.

The second is filing a scattergun appeal: twenty grounds, most of them general, with the one strong point buried on page fourteen. Put the best defect first and prove it.

The third is ignoring the respondents' reply. The proponent will usually say the hearing was properly held and file the minutes. If those minutes do not reflect what happened, you need affidavits from people who were there, and the video if you can get it. Silence is treated as acceptance.

The fourth is choosing the wrong case type. An EC that has expired, or a project that never had one, is not an appeal at all. Getting this wrong can mean the appeal is dismissed as not maintainable while the correct six-month window quietly closes.

Where to read next

If the clearance was granted after the project had already started, read our guide on post-facto environmental clearance, because the law there has moved more than once. If the EC exists but the project is not following it, see what to do when EC conditions are not followed.
