Using Photos, Lab Reports and RTI Replies as Evidence in the NGT

Yes, the NGT accepts photographs, videos, laboratory reports and RTI replies as evidence, and in most citizen cases they are the backbone of the application. The tribunal is not bound by the Code of Civil Procedure, so you do not need a witness box to get your case listed. You do need material a bench can trust at a glance: dated and located photos, a sample report from a proper laboratory, and official records obtained under RTI. Weak, undated or exaggerated evidence is the commonest reason a genuine complaint goes nowhere.

This guide is about the evidence itself: what to collect, how to keep it, how to put it before the tribunal and what the other side will say about it. If you are still working out the filing process, read our guide on how to file a case in the NGT first, and for turning this material into a petition see how to draft an NGT original application.

It covers photos and videos, private and official lab reports, RTI replies, your own complaint trail, and the mistakes that make a bench doubt a true story.

The essentials

Can I use photos, lab reports and RTI replies as evidence in the NGT?

Yes. In a citizen's application before the National Green Tribunal, these three kinds of material usually do most of the work. You attach them as annexures, refer to each in the facts, and verify the application on affidavit. The bench reads them at admission to decide whether the problem deserves notice or an inspection.

Each proves something different. Photos and videos show what the problem looks like and that it keeps happening. A lab report shows that the effluent, smoke or water actually breaches a standard, which a photo cannot. RTI replies show what the board, the municipal body or the district administration already knows, what permissions the polluter holds, and what the authorities have or have not done. A good file uses all three, each covering the others' weak spots.

None of this needs to be perfect. The tribunal expects honesty, some order and enough detail to check what you say, not a forensic report.

How does the NGT treat evidence compared with a regular court?

Section 19 of the National Green Tribunal Act, 2010 frees the tribunal from the Code of Civil Procedure and lets it regulate its own procedure, guided by natural justice. So there is usually no trial with witnesses and cross-examination. Facts come in through the application, replies, rejoinder and the documents attached, all supported by affidavits.

It also means the NGT often checks facts itself. Where the material raises a real doubt, the bench may ask the State Board or the CPCB for a factual report, or form a joint committee to inspect and take samples. So your evidence is not meant to win the case on its own. Its job is to persuade the bench that the problem is real, specific and serious enough to deserve an inspection or a direction.

Being free of strict procedure does not make the tribunal careless about reliability. Undated photos, unexplained samples and documents with missing pages get little weight, and the other side will attack exactly those gaps in its reply.

What makes a photo or video of pollution believable?

Context. A close-up of foaming water could be any drain in India. The same foam photographed with the factory gate, the outlet pipe and a recognisable signboard in the frame tells the bench exactly where it is. Take one wide shot that shows the location, then one of the source, then the close-up, from the same spot each time if you can, so the photos read as a series.

Time and place. Most phones record the date, time and GPS position inside the image file, so switch location on for the camera and check once that it is actually saved. A camera app that prints the date, time and coordinates on the photo also helps, because the bench can see them without opening the file. Keep a simple diary as well: date, time, what was happening, how long it lasted, who was with you.

Repetition. One photo shows one moment. Thirty photos over two months, at different times of day, show a pattern. For stack smoke, crusher dust or a DG set running all night, a short video with sound tells more than a still; for night-time discharge, record the time on screen. Copy originals from the phone to a computer, because WhatsApp and similar apps compress images and usually strip the date and location data.

Avoid anything that looks staged: no filters, no cropping out landmarks, no photos from the internet or another site. Do not trespass to get a better shot, and check the current drone rules before flying one near any site.

Do I need a certificate for photos, videos and WhatsApp messages?

In ordinary courts, an electronic record such as a photo, video or message is proved with a certificate under section 63 of the Bharatiya Sakshya Adhiniyam, 2023, which replaced section 65B of the old Evidence Act. The NGT is not strictly bound by those rules, and at the filing stage photos are routinely accepted on the strength of the applicant's affidavit. Even so, giving a short certificate for your key electronic records costs nothing and takes away an easy objection.

The certificate is a short signed statement by the person who took the photos or controls the device. It identifies the device, says how the copies were made and confirms they are true copies of the originals. Keep the phone or memory card, with the originals, until the case is over.

Screenshots of messages, posts or online news work the same way: print the full screen with the date and sender visible, note when you took it, and keep the device. Newspaper reports show that a problem is locally known, but on their own they are weak proof of facts.

Will a private lab report on water or air samples be accepted by the NGT?

It will be read, and it can help a great deal, but how much weight it gets depends on how the sample was taken. The first question any respondent asks is: who collected this sample, from where, in what container, and how did it reach the laboratory? If you cannot answer, the report is easy to brush aside, however alarming its numbers.

Pollution boards follow a statutory procedure when they sample. Section 21 of the Water Act and section 26 of the Air Act require notice to the occupier, and the sample is divided, sealed and sent for analysis in a set manner. Your own sample cannot follow that procedure, which is why a private report has limited value in a prosecution. In an NGT application its purpose is different: it shows the tribunal there is a real basis for official sampling, and that is often enough to get a joint committee sent to the site.

To make a private sample count, use a laboratory accredited by NABL for the parameters you want, or one recognised under the Environment (Protection) Act, and ask it to send its own staff or at least to tell you how to collect and preserve the sample. Film the collection: the spot, the bottle, the label, the seal, the time. Keep a written chain of custody. Ask for parameters that match the relevant standard, such as pH, BOD, COD, suspended solids and heavy metals for effluent, rather than a generic test.

Read the report honestly. A single grab sample slightly over one parameter proves less than people hope. Compare it with the correct standard (discharge standards at an outlet, drinking water standards for a handpump, ambient standards for air) and say plainly what it shows. For help with the science, see our guide on when expert or laboratory evidence is needed.

Which sample reports carry the most weight?

A practical ranking, not a legal rule. A careful private report can outweigh a sloppy official one.

Where an official report and yours disagree, do not just call the official one false. Point to the difference in date, sampling point, operating condition or method, and ask for a fresh sample taken in your presence.

How do RTI replies help an NGT case, and what should I ask for?

RTI replies are often the strongest evidence a citizen can get, because they are the authority's own records. If the board's inspection report already records that the effluent treatment plant was bypassed, or that the unit had no valid consent to operate, nobody can easily say you invented it. And if the reply shows that the board received ten complaints and did nothing, that inaction is itself a ground before the tribunal.

Under the Right to Information Act, 2005, the public information officer must reply within 30 days. If the reply is incomplete or does not come, file a first appeal in the same office, generally within 30 days, and then a second appeal to the Information Commission, generally within 90 days. Pay the prescribed fee (₹10 under the central rules; states set their own) and keep proof of dispatch.

Ask narrow, document-based questions. Not "why has the board not acted", which invites a vague answer, but "certified copies of all inspection reports and sample analysis reports of M/s ABC Industries, village __, from 1 January 2025 to date". Ask for the consent orders and their conditions, show-cause notices and replies, closure directions, and the action taken on your complaints by date. You can also ask to inspect the file and take copies.

When Advocate B.K. Singh reads an RTI bundle before filing, he looks first for the gap between what the authority recorded and what it did next, because that gap, more than any photograph, is what makes a bench ask the authority to explain itself.

RTI requests worth making before an NGT case

How to build and present your evidence file for the NGT

This order works for most pollution and encroachment complaints. A good file takes four to eight weeks, and the time limit keeps running, so start early.

File only what helps. Put a small, telling selection in the main file and keep the rest ready in case the other side disputes it.

Do my earlier complaints count as evidence?

Very much. Written complaints to the board, the municipal body, the SDM or the police show that the problem is not new, that you went to the proper authorities first, and that they did not act. The tribunal often asks exactly that question.

Keep acknowledgments, diary numbers, dated emails, speed post receipts and screenshots of online complaints with reference numbers. If a complaint was closed as "no violation found", get that report too; it may contradict your photos from the same day.

The complaint trail also matters for time. NGT applications have time limits that run from when the cause of action first arose, and continuing pollution raises its own questions, which we explain in what is a continuing cause of action in NGT cases.

Mistakes that weaken genuine evidence

The most damaging mistake is exaggeration. An application says a factory has "poisoned the entire district" and attaches one report from one handpump. The bench notices. Say exactly what you can show: on these dates, effluent from this outlet entered this drain, and this sample exceeded these parameters.

The second is mixing up the source. In an industrial area with several units, a dirty drain does not show which unit caused it. Trace the outlet, and if you cannot tell, say so and ask that the authorities identify the source.

Smaller but common: photos with no dates, a report on the wrong parameters, RTI replies attached without the questions, annexures out of order, illegible scans, and regional-language documents with no English translation. Remember too that the other side sees everything; anything unfair, personal or irrelevant in your file will be quoted back at you.

Before you file: is your evidence ready?

What happens to my evidence once the case is filed?

The respondents' reply will usually attack your evidence: the photos are old, the sample was not taken properly, the unit was shut that day, the drain carries village sewage. Answer these points in a short rejoinder with any new material, rather than repeating your application.

If the tribunal forms a joint committee, its report often matters more than anything either side filed. Your evidence then becomes the yardstick for that report: if the committee came on a day the unit was shut, or sampled at the wrong point, your dated photos let you object. See how to object to a joint committee report.

Keep collecting while the case runs. Fresh photos and RTI replies showing the problem continues after notice often persuade a bench to pass firmer directions.
