The National Highways Authority of India v. Pandarinathan Govindarajulu
Background
NHAI undertook widening of National Highway 45-A between Villuppuram and Nagapattinam in Tamil Nadu (179.555 km, split into four packages) without obtaining prior environmental clearance. Farmers and public interest litigants filed writ petitions before the Madras High Court, which put the project on hold and directed NHAI to conduct an environmental impact study and obtain environmental and coastal-zone clearances before proceeding. NHAI appealed to the Supreme Court, arguing that environmental clearance was not legally required for this particular project.
Decision Breakdown
The Supreme Court examined the 2006 Environment (Protection) notification (as amended in 2013), which exempts highway expansion projects from needing environmental clearance where the additional land acquired for "right of way" does not exceed 40 metres on existing alignments or 60 metres on by-passes. It held that "right of way" includes ancillary facilities like toll plazas and rest areas, and since NHAI's land acquisition for this project fell within the exempted limits, no environmental clearance was required. The Court set aside the High Court's judgment but directed NHAI to strictly conform to the land-acquisition limits in the notification, to fulfil its reafforestation obligations (planting ten trees for every tree felled), and directed the Ministry of Environment to set up an expert committee to examine whether "segmenting" highway projects into smaller packages to avoid the 100 km threshold is permissible.
Lesson Learnt
Whether a government infrastructure project needs environmental clearance can turn on precise technical definitions (like how "right of way" is measured) in the governing notification, and even where clearance isn't legally mandatory, the executing agency still remains bound by other environmental safeguards such as mandatory re-plantation.
