S. Jagannath filed a PIL for enforcement of the Coastal Zone Regulation Notification, which declared coastal stretches up to 500 meters from the high tide line and the area between the low and high tide lines as regulated zones. The notification imposed various restrictions to protect ecologically fragile coastal areas. The Supreme Court held that the central government must constitute an authority under the Environment Protection Act to confer powers to protect these coastal areas. The authority was directed to implement the precautionary principle and polluter pays principle. The court also stated that no shrimp culture ponds could be constructed within the regulated coastal zones as defined in the notification.
