Mandatory effluent treatment as an input service supported Cenvat credit because pollution compliance was integral to manufacturing.

Cenvat credit was held admissible on effluent treatment services used to process industrial waste generated during manufacture, because compliance with pollution control permissions made such treatment a statutory necessity for continued production. The Tribunal treated the service as integrally connected with the manufacturing activity, not as a mere post-manufacture or peripheral process. Where a service is required for the business to function lawfully and is part of the uninterrupted manufacturing arrangement, it falls within the scope of input service. Denial of credit on this basis was therefore not sustainable.

Issues: Whether Cenvat credit was admissible on services used for effluent treatment of industrial waste generated during manufacture, when such treatment was mandatory under pollution control permissions.

Analysis: The effluent treatment service was not treated as a mere post-manufacture activity. The factory could not continue production unless the industrial waste was treated in accordance with the permissions granted under pollution control law. The treatment of effluents was therefore a statutory necessity and a vital part of the manufacturing arrangement. The Tribunal applied the settled principle that where a process is integrally connected with the manufacture of the final product and is required for the business to function lawfully, the related service falls within the scope of input service.

Conclusion: Cenvat credit on effluent treatment services was admissible and the denial of credit was not sustainable.

Ratio Decidendi: Services used for mandatory pollution-control and effluent-treatment compliance, being integrally connected with the uninterrupted manufacture of the final product, qualify as input services for Cenvat credit.
