The Supreme Court directs that the expert committee tasked with defining the Aravalli hills and related ranges should consult stakeholders during its work. The court says the panel must involve domain expertise and also seek input from relevant stakeholders, while maintaining a compact, functional structure. The court cautions against making the committee too large or unwieldy, emphasizing that effectiveness should not be sacrificed for broader participation. It also stresses that the committee should work collaboratively with experts familiar with the region’s environmental, geographical, and related considerations. The court’s observations are aimed at balancing two priorities: ensuring that the definition process reflects expert knowledge and incorporating stakeholder perspectives, without turning the committee into an excessively large body. The decision therefore focuses on how the committee is constituted and how it conducts consultations, rather than on the final definition itself.
