Service tax on dredging services and Cenvat credit for dredger repair spares: pre-18.04.2006 rate upheld; demands largely set aside

Service tax rate on dredging services post-enhancement from 10% to 12% w.e.f. 18.04.2006 turned on the taxable event; applying SC law on the binding nature of circulars and HC precedent that rendition of service is the point of taxation, the Tribunal held services rendered prior to 18.04.2006 attracted 10% and not 12%, setting aside the differential demand. On Cenvat credit, spares/parts used to repair dredgers deployed for taxable output service were held to be "inputs" under the CCR, allowing credit and quashing denial. Since the items were inputs, the restriction to 50% credit in the first year was inapplicable, and the related demand failed. However, interest on wrongly availed but reversed credit remained payable under SC precedent, and was sustained to that extent; appeal partly allowed.

ISSUES PRESENTED AND CONSIDERED

1) Whether the enhanced service tax rate applied where invoices and payments were post-enhancement, but the dredging services were rendered prior to the enhancement date.

2) Whether spares/parts used for repair of dredgers (used for providing taxable output service) were to be treated as "inputs" eligible for credit under the Cenvat Credit Rules, 2004, including credit on stock lying when an exempted service became taxable.

3) Whether the demand restricting availment of only 50% credit in the first year (treating the items as capital goods) survived once the items were held to be inputs.

4) Whether interest was payable on credit wrongly taken but later reversed, even if the credit was admittedly not utilised during the period prior to reversal.

ISSUE-WISE DETAILED ANALYSIS

1) Applicability of 10% vs 12% service tax rate based on date of rendition of service

Legal framework (as discussed): The Court proceeded on the principle that, for the relevant period, the taxable event for service tax was the rendition/provision of service, not receipt of payment, and departmental circulars could not override law as declared by higher courts.

Interpretation and reasoning: The Court found evidence on record (debit notes/invoices) showing services were rendered prior to 18.04.2006, and this factual position was not disputed. It held that the Department's approach-applying the post-enhancement rate based on invoice/payment dates and relying on Board circular guidance-could not prevail where the taxable event was rendition of service. The Court applied the reasoning that circulars contrary to the law on taxable event cannot determine the applicable rate.

Conclusion: The applicable rate was held to be 10% (rate prevailing when services were rendered), and not 12% merely because invoicing/payment occurred after 18.04.2006.

2) Eligibility of credit on spares/parts used for repair of dredgers as "inputs"

Legal framework (as discussed): The Court considered entitlement to credit under the Cenvat Credit Rules, 2004, including Rule 3(3) (credit on "inputs" lying in stock when an exempted service became taxable), and addressed the input/capital goods characterisation for items used in providing output service.

Interpretation and reasoning: The Court followed its own earlier decision concerning the same assessee, holding that spares and parts used for repair of dredgers, where dredgers were used for providing taxable dredging service, have sufficient nexus with output service and can be treated as inputs. On that basis, the Court held that these goods were eligible for credit as inputs, including under Rule 3(3) where applicable.

Conclusion: Credit on such spares/parts was allowed by treating them as inputs; the contrary demand could not be sustained.

3) Demand alleging wrongful availment of 100% credit by treating the items as capital goods

Legal framework (as discussed): The Department's case assumed the items were capital goods, attracting a staged credit mechanism (50% in the first year and balance later).

Interpretation and reasoning: The Court held that, since the items were properly classifiable as inputs (Issue 2), the foundation for restricting credit on the capital-goods basis fell. The Court further recorded that, once treated as inputs, the impugned restriction did not survive, and stated there was no bar to taking 100% credit in the stated context.

Conclusion: The demand based on capital-goods restriction (50% first year) was set aside as unsustainable.

4) Interest on wrongly taken but unutilised credit which was later reversed

Legal framework (as discussed): The Court applied the settled position from the Supreme Court ruling relied upon in the judgment that interest is payable on wrongly taken credit even if subsequently reversed, for the relevant period.

Interpretation and reasoning: The Court noted that the credit was reversed later and was admittedly not utilised; however, it held that interest liability still arose for the period the credit remained unreversed, in line with the binding Supreme Court view.

Conclusion: Interest demand was upheld to the limited extent of the quantified amount of Rs. 34,996/-; all other demand confirmations in the impugned order were set aside.
