Coastal regulation enforcement and environmental limits: SC upheld core CRZ controls, struck down arbitrary relaxations, and modified FSI treatment.

Coastal Regulation Zone norms were treated as valid environmental controls under the Environment (Protection) Act, 1986, and the Court stressed that such rules must be strictly implemented because tolerance of violations undermines ecological protection and the right to life. The 19.2.1991 notification was upheld as legally valid, while complaints of non-implementation were left to be pursued before the High Courts and through administrative compliance. The 18.8.1994 relaxations were partly struck down: the 200 metre construction proviso and the reduction of the tidal river, creek and backwater restriction to 50 metres were held arbitrary and illegal, while certain limited permissions were upheld and the FSI rule was modified.

Issues: (i) Whether the Coastal Regulation Zone notification of 19.2.1991 had been implemented and enforced in accordance with law. (ii) Whether the amendments introduced by the notification of 18.8.1994 were valid in so far as they relaxed the no-development restrictions in coastal areas.

Issue (i): Whether the Coastal Regulation Zone notification of 19.2.1991 had been implemented and enforced in accordance with law.

Analysis: The notification was issued under the Environment (Protection) Act, 1986 and the Environment (Protection) Rules, 1986 to regulate coastal development and preserve ecological balance. The record showed widespread delay and non-compliance in preparing and approving Coastal Zone Management Plans and inadequate monitoring by the concerned authorities. The Court emphasised that enactment of environmental law is ineffective unless it is implemented, and that continued tolerance of violations defeats the object of the statute and harms the environment and the right to life.

Conclusion: The notification of 19.2.1991 was held to be valid and required strict enforcement, but the grievance of non-implementation was not finally adjudicated by direct merits findings in this Court and was instead directed to be pursued before the concerned High Courts and through further administrative compliance.

Issue (ii): Whether the amendments introduced by the notification of 18.8.1994 were valid in so far as they relaxed the no-development restrictions in coastal areas.

Analysis: The Court examined each amendment against the object of coastal protection and the recommendations of the expert committee. It held that the proviso permitting construction within the 200 metre no-development zone conferred arbitrary, uncanalized and unguided power and was liable to be struck down. The reduction of the restriction near tidal rivers, creeks and backwaters from 100 metres to 50 metres was also found arbitrary and illegal. By contrast, permitting goal posts and lamp posts, allowing basements subject to groundwater safeguards, and permitting green and barbed wire fencing with protection of public access were upheld. On FSI, the Court modified the amendment and directed that only half of the land in the no-development zone would be counted for permissible FSI.

Conclusion: The 18.8.1994 notification was partly upheld and partly quashed, with one amendment modified by the Court and the others sustained or invalidated according to their environmental impact.

Final Conclusion: The decision preserved the validity of the original coastal regulatory framework, struck down or modified the environmentally unsafe relaxations, and issued directions to secure implementation through the appropriate High Courts and the competent authorities.

Ratio Decidendi: Environmental regulations aimed at protecting coastal ecology must be enforced in a manner that is non-arbitrary, guided by relevant factors, and consistent with the statutory objective of preventing ecological degradation and protecting the right to life.
