Case Note & Summary
This batch of writ petitions was filed by various individuals and associations challenging the demolition of constructions on water bodies and river banks in Tamil Nadu, particularly in Coimbatore district. The petitioners claimed that they had obtained necessary approvals and that the demolition actions were arbitrary. The respondents, including the State of Tamil Nadu, Public Works Department, and local authorities, argued that the constructions were illegal encroachments on water bodies and river banks, causing environmental damage and flooding. The court examined the legal framework including the Public Trust Doctrine, Sustainable Development, Precautionary Principle, and relevant statutes such as the Tamil Nadu Protection of Tanks and Water Bodies Act, 2007 and the Tamil Nadu Land Encroachment Act, 1905. The court held that water bodies are public trust resources and the State has a duty to protect them. The court found that the petitioners had not produced valid title or approvals and that the constructions were illegal. The court dismissed the petitions and directed the authorities to continue demolition and restoration of water bodies. The court also issued directions for a comprehensive survey and removal of all encroachments on water bodies across the state.
