Service tax classification dispute defeated as extended limitation, post-negative list demand and vague show-cause notice all failed.

The extended limitation period for a service tax demand under Business Auxiliary Service was held inapplicable because the activity was already known to the Department and the classification remained uncertain, showing no basis for invoking suppression. The demand for the period after 01.07.2012 also failed because it was framed under the pre-negative list Business Auxiliary Service category, even though the negative list regime had already commenced. The show-cause notice was additionally found defective for not specifying the particular clause of Business Auxiliary Service, leaving the basis of liability unclear. Full relief was therefore granted to the assessee.

Issues: (i) whether the extended period of limitation was invokable for the demand of service tax under Business Auxiliary Service; (ii) whether the demand for the period after 01.07.2012 was sustainable when no demand was raised under the negative list regime; (iii) whether the show-cause notice was defective for not specifying the particular clause of Business Auxiliary Service.

Issue (i): whether the extended period of limitation was invokable for the demand of service tax under Business Auxiliary Service.

Analysis: The activity had been known to the Department much before issuance of the show-cause notice, and the Department itself had treated similar activity differently in respect of the appellant's sister concern. The uncertainty as to whether the activity fell under Cargo Handling Service or Business Auxiliary Service showed absence of a definite departmental view.

Conclusion: The extended period of limitation was not invokable, in favour of the assessee.

Issue (ii): whether the demand for the period after 01.07.2012 was sustainable when no demand was raised under the negative list regime.

Analysis: From 01.07.2012, the negative list regime came into force. The demand, however, was confirmed under the pre-negative list category of Business Auxiliary Service and not under the post-01.07.2012 regime applicable to the activity. The cited Tribunal view was followed to hold that a demand founded on an extinct pre-2012 basis could not sustain for the later period.

Conclusion: The demand for the period after 01.07.2012 was not sustainable, in favour of the assessee.

Issue (iii): whether the show-cause notice was defective for not specifying the particular clause of Business Auxiliary Service.

Analysis: The notice alleged liability under Business Auxiliary Service without invoking any specific clause, leaving the basis of demand unspecified.

Conclusion: The show-cause notice was defective, in favour of the assessee.

Final Conclusion: The service tax demand failed both on limitation and on merits for the post-01.07.2012 period, and the assessee obtained full relief from the impugned order.

Ratio Decidendi: Where the Department itself is uncertain about the correct tax classification and the activity was already known to it, the extended period of limitation cannot be invoked; further, a demand cannot be sustained for a period governed by a new tax regime when the notice proceeds only on the abolished pre-existing classification.
