Mutuality and estoppel limit service tax liability where a members' club does not provide taxable mandap keeper services.

Estoppel cannot validate an inapplicable tax levy: mistaken registration and return filing did not preclude challenge where the service tax provisions were otherwise unavailable. A members' club operating on mutuality was also held outside the statutory meaning of mandap keeper, because the provisions contemplated a commercial letting of a mandap to a separate client for consideration, not internal use by members. On that footing, the club's activities did not constitute taxable service under the impugned provisions, the notices and registration certificate were quashed, and service tax liability was rejected.

Issues: (i) Whether the petitioner was barred by estoppel from disputing applicability of the service tax provisions after obtaining registration and filing returns; (ii) Whether a members' club, operating on the principle of mutuality, fell within the meaning of mandap keeper and taxable service so as to be liable to service tax.

Issue (i): Whether the petitioner was barred by estoppel from disputing applicability of the service tax provisions after obtaining registration and filing returns.

Analysis: Estoppel cannot operate against a statute. If a statutory provision is inapplicable, a mistaken registration or filing of returns does not create liability or preclude challenge to the action taken under error.

Conclusion: The objection of estoppel was rejected against the respondent.

Issue (ii): Whether a members' club, operating on the principle of mutuality, fell within the meaning of mandap keeper and taxable service so as to be liable to service tax.

Analysis: The statutory definitions contemplated letting out of a mandap for consideration to a client for organising official, social or business functions, which imports a commercial transaction with a separate user. The club's facilities were held for the mutual use of members, with no third-party commercial letting or independent client relationship. On that footing, the doctrine of mutuality applied, and the club's activities did not answer the statutory description of taxable service.

Conclusion: The petitioner was not liable to service tax under the impugned provisions.

Final Conclusion: The writ petition succeeded, the impugned notices and registration certificate were quashed, and the club was held outside the service tax net on the footing of mutuality.

Ratio Decidendi: A mutual members' club, absent commercial letting to a separate client, does not fall within a taxing provision framed around a mandap keeper providing services for consideration.
