India's top court's 2025 nod to 100-metre Aravalli rule revives an old debate it once rejected

Critics warn the new definition could leave lower, ecologically important hills vulnerable to mining and development. Environmentalists and lawyers argue the shift may undermine years of judicial oversight and scientific assessment.
