Statutory service by prescribed modes and strict limitation rules defeated a service tax demand based on WhatsApp notice service.

Statutory service of a show cause notice must comply strictly with the prescribed modes, and WhatsApp service is not a valid substitute where the law requires tender, registered post with acknowledgment due, speed post with proof of delivery, approved courier, or affixation after failed attempts. The notice was therefore procedurally defective. On limitation, the extended period under service tax law cannot be invoked without affirmative material showing fraud, collusion, wilful misstatement, suppression of facts, or intent to evade tax. A bona fide view that the activity fell within the negative list was inconsistent with such invocation. The demand and appellate confirmation were set aside.

Issues: (i) whether service of the show cause notice through WhatsApp was valid under the prescribed statutory modes; (ii) whether the demand was barred by limitation, including the extended period under the service tax law.

Issue (i): whether service of the show cause notice through WhatsApp was valid under the prescribed statutory modes

Analysis: The statutory scheme governing service permits only the modes expressly set out in the provision, namely tender, registered post with acknowledgment due, speed post with proof of delivery, approved courier, and in default thereof affixation at the place of business or residence, or on the notice board of the issuing authority. Service through WhatsApp is not one of the prescribed modes and no material showed any prior attempt to serve the notice through the statutory channels at the appellant's current address.

Conclusion: Service through WhatsApp was not valid, and the notice suffered from a fundamental procedural infirmity.

Issue (ii): whether the demand was barred by limitation, including the extended period under the service tax law

Analysis: Even assuming valid communication through WhatsApp, the larger part of the demand related to an earlier financial year and fell beyond the five-year extended period. For the residual amount, the record did not establish fraud, collusion, wilful misstatement, suppression of facts, or any intent to evade tax. A bona fide belief that the activity was covered by the negative list was inconsistent with invocation of the extended limitation period in the absence of positive evidence of suppression or deceit.

Conclusion: The demand was not sustainable in limitation, and the extended period could not be invoked.

Final Conclusion: The impugned demand and appellate confirmation were set aside, and the assessee obtained complete relief from the service tax demand.

Ratio Decidendi: Statutory modes of service must be strictly complied with, and the extended period of limitation in service tax matters cannot be invoked without affirmative material showing fraud, wilful suppression, or intent to evade tax.
