Case Note & Summary
The Supreme Court addressed the safety concerns surrounding the Mullaperiyar Dam amidst ongoing litigation involving multiple writ petitions and a special leave petition. The court noted the enactment of the Dam Safety Act, 2021, which received presidential assent on December 13, 2021, and was notified on December 14, 2021, with an appointed date of December 30, 2021. The Act establishes a comprehensive framework for dam safety, including the formation of the National Dam Safety Authority (NDSA) responsible for the oversight of dam operations and maintenance. The court highlighted the need for a statutory structure to replace the existing Supervisory Committee, which had been functioning satisfactorily since a previous judgment. However, recognizing the time required to establish the NDSA, the court decided to strengthen the existing Supervisory Committee by including technical experts from both Tamil Nadu and Kerala. The court mandated that this reconstituted committee would assume the responsibilities of the NDSA until it became fully operational, ensuring compliance with the provisions of the 2021 Act. The court emphasized the importance of cooperation from the state parties to ensure the effective implementation of safety measures and directed the concerned ministry to provide logistical support to the committee. The court scheduled a follow-up hearing for compliance reporting and allowed for urgent applications in case of exigencies before the next date. The decision underscored the urgency of establishing the NDSA to prevent potential disasters related to dam safety.
