Who Can Appeal, and Under What Provision
An order granting or refusing environmental clearance can be appealed to the National Green Tribunal under Section 16(h) of the NGT Act, 2010. The appeal can be filed by any person aggrieved, including on environmental-interest grounds, and is not limited to a direct commercial rival of the project proponent.
The 30-Plus-60-Day Limitation Window
The limitation period is a strict 30 days from the date the environmental clearance order is communicated, or otherwise made known to the appellant, calculated from the earliest date of effective public disclosure, such as upload on the relevant authority's website. The NGT has power to condone a further delay of up to 60 days on sufficient cause being shown, making 90 days the absolute outer limit.
Following an NGT Principal Bench practice direction, appeals filed beyond that 90-day outer limit are virtually always dismissed as time-barred, regardless of the merits of the environmental objections raised. Because the clock runs from disclosure rather than actual knowledge, a project proponent should ensure proper, timely publication of the clearance to start and close the limitation window, while an intending objector must monitor clearance portals proactively rather than waiting for formal personal notice.
What the NGT Can Do on a Successful Appeal
On a successful appeal, the NGT can modify the conditions attached to the clearance, remand the matter for fresh consideration by the authority, or quash the clearance outright, each with significant practical consequences for a project that may already be underway.
Frequently Asked Questions
From when does the 30-day limitation period run?
From the date the environmental clearance order is communicated, or the earliest date of effective public disclosure such as a website upload, not from the appellant's actual subjective knowledge of it.
Can the NGT condone delay beyond 30 days?
Yes, the NGT can condone a further delay of up to 60 days on sufficient cause being shown, making 90 days from disclosure the absolute outer limit.
What happens if an appeal is filed after 90 days?
Following NGT Principal Bench practice, such an appeal is virtually always dismissed as time-barred, regardless of how strong the underlying environmental objections may be.
