Extended Limitation Cannot Be Invoked Where Sub-Contractor Acted on Bona Fide Belief: Principal Commissioner Vs Mammen Engineering Works

Overview of the Dispute

The Chhattisgarh High Court recently delivered a significant ruling in the matter of Principal Commissioner Vs Mammen Engineering Works, addressing a fundamental question in indirect taxation — whether the extended period of limitation under the proviso to Section 73(1) of the Finance Act, 1994 can be validly invoked against an assessee who withheld service tax disclosure based on a genuine and legally defensible belief that the primary liability had already been discharged by another party.

The Court upheld the Customs, Excise & Service Tax Appellate Tribunal (CESTAT) order dated 01.08.2019, which had directed recalculation of service tax liability confined strictly to the normal limitation period under Section 73(1), expressly excluding the extended limitation period under the proviso thereof.

Background Facts

Mammen Engineering Works, the respondent in this appeal, functioned as a sub-contractor and had received aggregate payments amounting to ₹19,30,94,411 for fabrication, erection, and commissioning work executed on behalf of two principal contractors — M/s Gannon Dunkerley & Co. Ltd., New Delhi and M/s Viraj Steel & Energy Ltd., New Delhi.

The respondent's position throughout the proceedings was straightforward: the principal contractors had already discharged the service tax obligation on the entire contract value and had issued formal certificates to that effect. Accordingly, the respondent neither collected service tax from the principal contractors nor reflected any such liability in its ST-3 returns, proceeding on the reasonable assumption that further payment would result in double taxation on the same transaction.

During the course of a departmental audit, it surfaced that the ST-3 returns filed by the respondent contained no disclosure of any service tax payment or liability pertaining to the sub-contracted works. This triggered the issuance of a show cause notice dated 19.10.2012, covering financial years 2007-08 through 2010-11 and the trial balance for 2011-12 (up to December 2011), with the Department invoking the extended period of limitation by alleging suppression of facts and wilful non-disclosure.

Procedural Journey

Upon adjudication, the Commissioner, Central Excise & Customs, Raipur confirmed the service tax demand vide order dated 17.12.2013, simultaneously levying interest and penalty on the respondent. The Commissioner's findings went against the respondent notwithstanding the certificates of payment produced by the main contractors.

Aggrieved by this determination, Mammen Engineering Works approached CESTAT, which examined the matter and concluded that invocation of the extended limitation was not warranted on the facts of the case. The Tribunal accordingly remitted the proceedings back to the Commissioner with specific directions to recompute the service tax liability only for the normal period stipulated under Section 73(1) of the Finance Act, 1994, without applying the proviso extending limitation to five years.

The Department, dissatisfied with this outcome, filed an appeal before the Chhattisgarh High Court, contending that a substantial question of law had arisen warranting judicial interference.

The High Court was called upon to determine two interconnected issues:

  1. Whether the extended period of limitation under the proviso to Section 73(1) of the Finance Act, 1994 was legitimately invocable in the facts and circumstances of this case.
