Procedural limitation non-retrospectivity: six-month rule does not apply retroactively and one-year extension validates prior Cenvat credits.

Challenge concerns temporal application of limitation provisions to availment of Cenvat credit. The note states that the six-month proviso to Rule 4(7) enacted w.e.f. 01.09.2014 cannot be applied to invoices/bills of entry issued before that date because procedural limits do not extinguish vested or accrued substantive credit rights absent express retrospective language. The subsequent amendment extending the period to one year is characterised as remedial and held to validate credits availed within that enlarged period for subsisting claims. Consequently, demands, interest and penalties predicated on denial of such admissible credit lack statutory foundation.

Issues: (i) Whether the six-month limitation introduced under the proviso to Rule 4(7) of the Cenvat Credit Rules, 2004 w.e.f. 01.09.2014 applies to invoices/bills of entry issued prior to 01.09.2014; (ii) Whether the amendment extending the time limit to one year w.e.f. 01.03.2015 validates credit availed within one year from the date of such invoices; (iii) Whether denial of credit along with recovery of interest and imposition of penalty is sustainable.

Issue (i): Whether the six-month limitation introduced under the proviso to Rule 4(7) of the Cenvat Credit Rules, 2004 w.e.f. 01.09.2014 applies to invoices/bills of entry issued prior to 01.09.2014.

Analysis: Prior to insertion of the proviso w.e.f. 01.09.2014 no time limit existed for availment of Cenvat credit; the right to credit accrues on receipt of inputs/input services and payment of duty and is a substantive right. The proviso contains no express retrospective language and therefore cannot curtail vested or accrued rights. Consistent judicial authorities establish that procedural amendments imposing a limitation do not apply retrospectively in the absence of clear legislative intent; Section 38A of the Central Excise Act, 1944 preserves accrued rights on amendment.

Conclusion: The six-month limitation introduced w.e.f. 01.09.2014 does not apply to invoices/bills of entry issued prior to that date.

Issue (ii): Whether the amendment extending the time limit to one year w.e.f. 01.03.2015 validates credit availed within one year from the date of such invoices.

Analysis: The amendment by Notification No. 6/2015-CE (NT) dated 01.03.2015 extended the permissible period to one year. An amendment enlarging a limitation period is remedial and applies to subsisting claims so long as no substantive bar had extinguished the right prior to the amendment. The invoices in question were issued when no limitation existed and the credit was availed within one year, bringing the availment within the enlarged period; governing authorities support application of the extended period to validate such credits.

Conclusion: The amendment extending the time limit to one year applies and validates the Cenvat credit availed within one year from the date of the invoices.

Issue (iii): Whether denial of credit along with recovery of interest and imposition of penalty is sustainable.

Analysis: If the Cenvat credit is legally admissible, the statutory basis for recovery under Rule 14 and for interest and penalty under Rule 15(1) ceases to exist. The prior conclusions that the limitation cannot be applied retrospectively and that the extended one-year period validates the credit remove the foundation for demand, interest and penalty.

Conclusion: Denial of the credit and the consequent recovery of interest and imposition of penalty are unsustainable.

Final Conclusion: The appeal is allowed; the impugned order setting aside the credit, recovery, interest and penalty is set aside and the Cenvat credit is held to be admissible with consequential reliefs in accordance with law.

Ratio Decidendi: A procedural amendment introducing or shortening a time limit for availment of tax credits cannot be applied retrospectively to extinguish vested or accrued rights in the absence of express retrospective language; conversely, a subsequent remedial amendment extending the limitation period applies to subsisting claims and validates credits availed within the extended period where no substantive bar had intervened.
