Projects, violations, permissions, approvals and orders which affect communities often happen before most people realize what the legal documents mean. You may realize there is an environmental violation, an improper clearance, or an order passed harming environment-related interests long after the date of the order. You may file a case before National Green Tribunal (“NGT”) only when you become aware of such facts. The simple question is: Can delayed knowledge help extend the limitation period for filing an appeal before NGT? Do remember that the concept of limitation is not dealt with leniently under Indian environmental laws. The National Green Tribunal Act, 2010 prescribes time bars for filing appeals and applications before NGT. Any delay in filing can be objected to by the opposite party even if you contend that you became aware of the facts later. But can delayed knowledge help in certain cases? Yes, if facts and circumstances are deemed suitable by NGT. The nature of order, date of communication, date of discovery of cause of action, and facts brought before NGT are some considerations. Residents, residents’ welfare associations, environmental groups, and stakeholders often take limitation rules wrongfully. They think that if they discover the problem later, they can go to NGT anytime. Such an approach can land you in serious legal troubles. NGT will look into the legitimacy of the delay. Was the knowledge actually unavailable earlier? Did you approach NGT within a reasonable time after you became aware of the facts? Delayed knowledge is construed strictly by NGT. If you live in Delhi NCR, Noida, Gurugram, Ghaziabad, Faridabad or any other developing cities in India, chances are high that your environmental dispute is related to real estate construction, pollution issues, mining operations, industrial permissions, construction debris or approvals. In such cases, time plays a crucial factor whether NGT will hear your dispute or not. Analysing limitation, the documents you have, environmental impact of the violations, and your procedural position before NGT is critical before moving forward with your case. BK Singh Advocate / NGT Lawyers evaluates whether you can use delayed knowledge as an argument to file an appeal before NGT or limitation may bar your legal remedy. Why does delay become relevant? Delay cannot be ignored because the NGT does not adjudicate environmental appeals solely based on when a person became aware of a controversy in his personal life. The Tribunal looks at limitation provisions under statute, notice of orders, the availability of information, etc. along with the facts and circumstances of the case in general. Environmental orders are also published by way of official gazettes, notifications, public hearings, regulatory portals or government websites. The concerned party cannot take refuge in non-knowledge all the time to avoid limitation. On the other hand, environmental controversies can also be a case of concealment where damage or violation is observed only when construction work is completed, during operation, after environmental pollution or loss of flora/fauna. Delay as a factor seeks to balance two interests; the protection of environmental rights versus interests in legal certainty. The project proponent, State, green authorities also have the right to understand that controversies over their projects will not stay pending forever. Environmental appeals are common in urban areas like Delhi NCR when a person realises groundwater depletion, air pollution, illegal activities, damage to plantation areas or environmental parameters being breached. The question here is not “when did the person aggrieved decide to file a complaint?” The question is “when did the legally actionable cause of action arise?” Any reasonable cause backed by documents, emails, inspection findings, registered complaints, RTI replies or proof which shows that the damage was come to know of at a later date can potentially hold value. Every appeal is fact specific. Time limit to file appeals under the National Green Tribunal Act, 2010 against certain orders, directions, permissions and environmental clearances is calculated from the date of such orders although the Act allows limited discretion to entertain delayed applications for sufficient cause shown before it. Delayed knowledge is a relative concept; the party claiming it must show why he could not have filed earlier with due diligence. Was the order brought to the knowledge of the person intending to file the petition by proper communication? Was the information available in public domain and did the intending applicant have any relation with the dispute? Was there inexcusable delay after acquiring knowledge? These are some of the questions which may be considered by the Tribunal. Suppose a residents’ welfare group files an appeal against approval of a project only after construction activity starts in an ecologically sensitive zone nearby. The plea that they came to know of the real impact and the material facts only much later would be analysed based on facts and the nature of the legal challenge. Individuals ought to approach a lawyer at the earliest opportunity when they become aware of a potential environment violation or when they receive an order that impacts their rights. Although the individual may wait until the limitation becomes the subject matter of dispute, they would have fewer legal remedies available to them. Individuals will need legal advice especially in the following circumstances Environment cases deal with technical as well as legal issues. Just because you discover a violation late does not necessarily mean you will have the right to file a petition with the NGT. It will depend on the facts of the case, any existing documents related to the case and what kind of proceedings you want to initiate. Only a lawyer would be able to evaluate whether you require to file an appeal or an application under original jurisdiction or a review based matter or something else. Also the forum and procedural law depends on the nature of dispute. Environment disputes can be handled by several authorities. Furthermore, consulting at the early stages would help you from making avoidable errors. Such as filing a complaint only by verbally, not collecting evidence to support your claim or not understanding when the limitation could be calculated.
