Case Note & Summary
The dispute arose regarding the requirement of environmental clearance for the expansion of National Highway 45-A from Villuppuram to Nagapattinam. The High Court had ruled that environmental clearance was necessary, leading to the appeals by the National Highways Authority of India (NHAI). The project was divided into four packages, each less than 100 km, and the NHAI contended that environmental clearance was not required as the additional right of way did not exceed specified limits. The High Court, however, held that segmentation of the project to avoid environmental clearance was impermissible. The Supreme Court analyzed the relevant Notifications and concluded that prior environmental clearance was only necessary if the additional right of way exceeded 40 meters on existing alignments and 60 meters on realignments for projects greater than 100 km. The court emphasized that segmentation of projects to evade environmental regulations would render the Notifications ineffective. It directed the formation of an expert committee to evaluate the permissibility of project segmentation beyond 100 km and mandated compliance with reafforestation requirements. Ultimately, the Supreme Court set aside the High Court's judgment and allowed the appeals, clarifying the conditions under which environmental clearance is required.

B) Environmental Law - Segmentation of Projects - Impermissibility of segmentation to avoid environmental clearance - Environment (Protection) Act, 1986, Section 3 - The court ruled that segmentation of projects to evade environmental clearance is not permissible, emphasizing the need for compliance with environmental regulations. (Paras 19-20). C) Environmental Law - Role of Expert Committee - Examination of project segmentation - Environment (Protection) Act, 1986, Section 3 - The court directed the formation of an expert committee to assess the permissibility of project segmentation beyond 100 km, highlighting the need for expert evaluation in such matters.
