Quick answer: In M/s. Hindalco Industries Limited v. Commissioner of Central Excise, Kolkata-II, decided on 10 September 2026, a Division Bench of the Calcutta High Court (Debangsu Basak and Aryak Dutt, JJ.) held that the extended, five-year period of limitation under the proviso to Section 11A(1) of the Central Excise Act, 1944 could not be invoked against Hindalco Industries for the demand periods Financial Year 2001-02 and Financial Year 2002-03. The demand — Rs. 6,29,920 together with interest and penalty, arising from alleged CENVAT-relevant stock shortages — rested entirely on figures drawn from the appellant’s own statutory Cost Audit Report, a document departmental officers had themselves witnessed being generated during stock verifications they personally attended. The Court held that what the proviso requires is a positive, deliberate act of suppression by the assessee, not merely the absence of departmental knowledge, and that a demand built entirely on a document the assessee was legally bound to prepare and produce cannot simultaneously be founded on that document’s suppression. The appeal was allowed, the Tribunal’s order set aside, and the Commissioner (Appeals)’s orders quashing the demand as time-barred were restored.
Key Takeaways
- The extended period under Section 11A’s proviso requires proof of a positive, deliberate act of concealment — not merely the Department’s subsequent discovery of a discrepancy. The Court held that “what is relevant for the purpose of the proviso is not the absence of knowledge on the part of the Department but a positive and deliberate act of suppression on the part of the assessee,” and that this ingredient was wholly absent on the facts before it.
- A demand founded entirely on a statutory record the assessee was bound to prepare and produce cannot simultaneously be founded on that record’s suppression. Hindalco’s Cost Audit Report was compiled under Section 233B of the Companies Act, 1956 and the Cost Audit (Report) Rules, 2001, and Rule 22 of the Central Excise Rules, 2002 entitled the Department to call for it at any time. The Court held the two propositions — statutory disclosure and concealment — could not stand together.
- Departmental presence at the very events said to have been concealed is itself evidence against suppression. Officers personally attended the appellant’s annual stock verifications on 9 February 2002 and 8 March 2003 — both within the disputed period — and witnessed the excesses and shortages later cited as the basis for the demand.
- A sixteen-month departmental delay after acquiring full knowledge, followed by a bare, unparticularised suppression allegation in the show cause notice, undercut the Revenue’s case on intent and on pleading. The Court treated the delay as evidence of the absence of the very intent the proviso presupposes, and separately held that the notices’ single, conclusory sentence on suppression failed the specificity Larsen & Toubro v. CCE requires.
- The judgment is confined to the Central Excise Act as it stood before the 2026 hearing, and its reasoning does not by its own terms extend to GST — but the statutory language it construes recurs in Section 74 of the CGST Act, 2017. Practitioners should read the decision as a Central Excise limitation ruling that illuminates, without directly deciding, an identically worded ingredient in the GST demand and recovery scheme.
1. Introduction
Central Excise Act demands frequently succeed or fail not on whether duty was in fact short-paid, but on whether the Revenue was entitled to reach back five years, rather than one, to raise the demand at all. Section 11A(1) of the Central Excise Act, 1944, as it stood at the material time, gave a Central Excise Officer one year from the “relevant date” to serve a demand notice; the proviso extended that period to five years, but only where the short-levy occurred “by reason of fraud, collusion, any wilful mis-statement or suppression of facts, or contravention of any provision of this Act or of the rules made thereunder with intent to evade payment of duty.” Where a demand rests on facts the Department already possessed, an assessee’s most natural defence is that nothing was suppressed from a Department that already knew. The Revenue’s most natural rejoinder — grounded in a well-known 2010 Gujarat High Court decision — is that the statute measures the extended period from a defined “relevant date,” not from any date of departmental “knowledge,” and that reading a knowledge exception into Section 11A rewrites it.
The Calcutta High Court confronted exactly this tension on 10 September 2026 in M/s. Hindalco Industries Limited v. Commissioner of Central Excise, Kolkata-II, an appeal under Section 35G of the Central Excise Act against a CESTAT, Kolkata order that had revived a duty demand the Commissioner (Appeals) had earlier quashed as time-barred. The Bench of Debangsu Basak and Aryak Dutt, JJ. sided with the assessee, holding that the Gujarat High Court’s reasoning in Neminath Fabrics does not answer the question this appeal actually posed, and that on the facts before it — a demand built entirely on a Cost Audit Report the Department had itself asked for, concerning shortages its own officers had watched being counted — the ingredients of the proviso were simply absent. This article sets out the facts, the Court’s reasoning on all three questions of law it decided, and what the decision means for excise, CENVAT and, by extension, GST demand practice where an identically structured “suppression” ingredient governs the extended period under Section 74 of the CGST Act.
2. Case summary and background
Hindalco Industries Limited, a large-scale manufacturer of aluminium, availed CENVAT credit of central excise duty paid on inputs used in its manufacturing operations. The dispute concerns Financial Years 2001-02 and 2002-03. By a letter dated 5 February 2001, the appellant informed the Department in advance of its annual stock verification and invited departmental officers to attend. Stock-taking was conducted on 10 February 2001, 9 February 2002 and 8 March 2003 — the latter two falling within the disputed period — with departmental officers present, and the resulting reports recorded every excess and shortage of aluminium at each stage of manufacturing.
On 26 September 2003, the appellant’s Cost Auditor prepared the Cost Audit Report for the year ending 31 March 2003, drawing on those same stock-taking reports and, in conformity with the Cost Audit (Report) Rules, 2001, setting out excesses and shortages of raw materials, work-in-progress, finished goods, scrap and wastage for that year and the two preceding years. The Court recorded that the excesses and shortages offset one another over the relevant period, so that there was no net shortage.
Departmental officers visited the appellant’s premises for audit on 16 December 2004, were shown the Cost Audit Report among other records, and issued a spot memo recording shortages on which CENVAT credit ought, in the Department’s view, to be reversed. No notice followed for nearly sixteen months. Four identically worded Show Cause Notices were eventually issued on 3 April 2006, invoking the extended period of limitation. Their entire averment on limitation read: “The said assessee had never before disclosed the fact of their non-compliance of the statutory bindings to the Central Excise Authorities thereby attracting the extended proviso to Section 11A of the Central Excise Act, 1944.”
Four Orders-in-Original dated 29 August 2007 confirmed the demand — an aggregate of Rs. 6,29,920 together with interest and penalty — on the reasoning that the appellant’s failure to proactively report the shortages amounted to suppression. On appeal, the Commissioner (Appeals), by four Orders-in-Appeal dated 26 February 2010, upheld the demand on merits but set it aside on limitation, holding it rested entirely on the Cost Audit Report, a statutory record. The Customs, Excise and Service Tax Appellate Tribunal, Kolkata, by order dated 22 December 2010, reversed the Commissioner (Appeals) and restored the four Orders-in-Original, prompting Hindalco’s appeal to the High Court. The appeal was admitted on three substantial questions of law: whether the extended period could be invoked where the demand rested solely on a statutory Cost Audit Report and the underlying facts were within departmental knowledge throughout; whether the Tribunal erred in reversing the Commissioner (Appeals) without recording any finding that the Department lacked such knowledge; and whether mandatory penalty under Section 11AC could follow if the extended period was unavailable. The Division Bench, in a judgment delivered by Aryak Dutt, J., with Basak, J. concurring, answered all three in the appellant’s favour after a hearing concluded on 19 August 2026.
3. Legal analysis
3.1 The statutory structure and the two-stage enquiry
The Court read Section 11A(1), together with its proviso and the “relevant date” definition in sub-section 3(ii), as posing “two distinct and sequential enquiries.” The first, and jurisdictional, enquiry is whether the ingredients described in the proviso — fraud, collusion, wilful mis-statement, suppression of facts, or contravention with intent to evade duty — in fact exist; that is a question of fact on which the burden lies wholly on the Revenue. The second enquiry, which arises “if, and only if,” the first is answered affirmatively, is from what point and for what span the notice is to be reckoned, a question the statute answers exhaustively through the defined “relevant date.” The Court held that “[a]uthorities addressed to the second cannot be transplanted to resolve the first” — a formulation aimed squarely at the Revenue’s principal authority, Commissioner of C. Ex., Surat-I v. Neminath Fabrics Pvt. Ltd. (2010 (256) E.L.T. 369 (Guj.)), on which the Revenue had placed principal reliance for the proposition that departmental knowledge is irrelevant to the extended period because the statute measures limitation from the defined “relevant date,” not from any date of knowledge.
3.2 Distinguishing Neminath Fabrics: what it decided and what it did not
Rather than disagreeing with Neminath Fabrics, the Court read it closely and confined it. It noted that Neminath Fabrics itself, at its paragraph 18, holds that the proviso comes into play “only when suppression is established or stands admitted” — and that suppression was in fact admitted there: the assessee’s own Director admitted a shortage of 1,93,717.50 L. Mtrs. of grey fabric and its clandestine removal without invoices or duty payment, corroborated by the receiving merchants’ own statements, with the goods never entered in the statutory registers. The Gujarat High Court had itself drawn the same line while distinguishing Commissioner of Central Excise and Customs v. Kwality Tube Industries (2009 (240) E.L.T. 20 (Guj.)), observing that where the alleged shortage is doubtful and suppression unestablished, “the matter stands on a different footing.”
The Calcutta High Court held that Hindalco’s case stood on that different footing: “There is no admission here, no statement of any officer of the appellant conceding removal, no evidence of clandestine clearance, no buyer, transporter or purchaser traced, no unaccounted receipt or payment, and no entry omitted from any register which the appellant was bound to maintain. There is nothing beyond a figure appearing in the appellant’s own statutory record[.]” The Court was also careful to note that Hindalco was not, as the assessee in Neminath Fabrics had unsuccessfully attempted, asking the Court to substitute a shorter, six-month period of limitation running from the date of departmental knowledge. Rather, “the appellant asks us to treat the Department’s contemporaneous knowledge as a fact from which the absence of suppression is to be inferred” — a use of the same fact for an entirely different, and in the Court’s view legitimate, purpose: “[o]ne cannot suppress from another that which the other already possesses, and possesses because one has oneself invited him to come and see it.”
3.3 The content of “suppression of facts”
Turning to the ingredients of the proviso itself, the Court held that “suppression of facts” takes its colour from the company it keeps alongside “fraud,” “collusion” and “wilful mis-statement,” citing the Supreme Court’s holdings that suppression means a deliberate act of withholding information the assessee knew it was obliged to disclose (Pushpam Pharmaceuticals Co. v. CCE, Bombay, 1995 (78) E.L.T. 401 (S.C.)), that it must be wilful and coupled with intent to evade duty (Cosmic Dye Chemical v. CCE, Bombay, 1995 (75) E.L.T. 721 (S.C.)), with Anand Nishikawa Co. Ltd. v. CCE (2005 (188) E.L.T. 149 (S.C.)) and Continental Foundation Jt. Venture v. CCE, Chandigarh (2007 (216) E.L.T. 177 (S.C.)) to the same effect, and that mere failure to pay or the mere discovery of a discrepancy does not supply the missing element (Uniworth Textiles Ltd. v. CCE, Raipur, 2013 (288) E.L.T. 161 (S.C.)).
Measured against that standard, the Adjudicating Authority’s reasoning — that the appellant’s failure to proactively notify the shortages was itself suppression — was held to invert the statutory burden: “[i]t converts the Revenue’s obligation to prove a positive act of concealment into an obligation on the assessee to volunteer information it was never require [sic] to furnish. If accepted, it would render the proviso applicable to every demand, for in every demand there is by definition something the assessee did not report. The proviso would then swallow the main section[.]” The Court further noted, applying Prolite Engineering Co. v. Union of India (1995 (75) E.L.T. 257 (Guj.)), that the periodical returns under Rule 12 of the Central Excise Rules, 2002 called for no disclosure of the shortages or excesses recorded in the Cost Audit Report, so that non-disclosure of what a return does not require cannot constitute suppression.
3.4 The self-defeating character of a demand founded on a statutory record
Central to the judgment is the Court’s treatment of the Cost Audit Report’s own provenance. The Report was prepared under Section 233B of the Companies Act, 1956, read with the Cost Audit (Report) Rules, 2001, and Rule 22 of the Central Excise Rules, 2002 expressly entitled the proper officer to require its production. “A demand built entirely upon such a document,” the Court held, “cannot simultaneously be a demand built upon suppression. The two propositions cannot stand together.” The Court had already taken this view in Commissioner of Service Tax, Kolkata v. M/s. Electro Steel Casting Ltd. (2025 (5) TMI 1218 (Cal.)), and found the Karnataka High Court to the same effect in Commissioner of Central Tax v. ABB Ltd. (2022 SCC OnLine Kar 1132) and the Allahabad High Court in CCE, Noida v. Accurate Chemical Industries (2014 (310) E.L.T. 441 (All.)), which holds that the extended period cannot be invoked merely because officers examined available records later than they might have. Separately, the officers’ personal presence at the 2002 and 2003 stock verifications was affirmatively inconsistent with concealment: “[a]n assessee who summons the Revenue to watch him count his stock is not an assessee who is hiding his stock.”
3.5 Pleading, delay, and the fate of the Section 11AC penalty
Two further strands supported the outcome. First, applying Larsen & Toubro Ltd. v. CCE, Pune-II (2007 (211) E.L.T. 513 (S.C.)), which requires fraud or suppression to be specifically pleaded, the Court held the notices’ single conclusory sentence — asserting non-disclosure without identifying any suppressed fact, disclosure obligation breached, or intent to evade — left the appellant unable to meet a charge never properly laid. Second, the Department’s sixteen-month inaction after acquiring full knowledge on 16 December 2004, before issuing notice only on 3 April 2006, was treated as evidence — not, consistent with Neminath Fabrics, as generating a fresh limitation period, but as a circumstance from which the absence of the requisite intent could properly be inferred, drawing support from CCE, Mangalore v. Pals Microsystems Ltd. (2011 (270) E.L.T. 305 (S.C.)) and Mopeds India Ltd. v. Collector of Central Excise (1991 (56) E.L.T. 241 (Tri.), affirmed 1991 (53) E.L.T. A79 (S.C.)). The Revenue’s reliance on Union of India v. Rajasthan Spinning & Weaving Mills (2009 (238) E.L.T. 3 (S.C.)) for mandatory Section 11AC penalty was held misplaced: that decision makes the penalty conditional on the proviso to Section 11A being satisfied, not free-standing of it. With the proviso’s ingredients absent, the Court answered all three questions for the appellant, restored the Commissioner (Appeals)’s orders, and declined to examine the merits, which the limitation finding made unnecessary.
3.6 What survives, and the limits of the analogy to GST
The judgment construes Section 11A as it stood at the material time and is addressed entirely to CENVAT-era facts; nothing in it discusses the Central Goods and Services Tax Act, 2017 or purports to bind GST adjudication. That said, Section 74(1) of the CGST Act employs the identical triad — a demand raised “by reason of fraud or any wilful misstatement or suppression of facts to evade tax” attracts an extended period, against Section 73’s ordinary period where no such element is present. The decision is instructive on the meaning of “suppression” and the burden of proving it under this textually parallel GST provision, but no GST adjudicating authority or court is bound to follow it, and the CGST Act’s own case law on Section 74 should always be checked directly.
4. Practical significance
For excise and CENVAT assessees still defending legacy demands from the pre-GST period, the judgment supplies a clear template: where a demand rests entirely on figures drawn from a document the assessee was statutorily bound to prepare and produce — a cost audit report, a statutory return, audited financial statements — and where departmental officers had contemporaneous, first-hand knowledge of the underlying facts, the extended period is vulnerable to challenge regardless of how the show cause notice characterises the assessee’s conduct. Litigants should specifically plead and document any instance of departmental attendance at stock verifications, audits, or inspections that coincide with the period later said to have been concealed, since such attendance is now judicial authority for an inference against suppression rather than a mere factual background detail.
The decision is also a pointed reminder on drafting and reviewing show cause notices invoking the extended period: a notice that merely asserts non-disclosure, without identifying the specific fact withheld, the specific disclosure obligation breached, and the intent to evade, is vulnerable on pleading grounds alone under Larsen & Toubro, independent of the merits. Counsel reviewing a notice or an Order-in-Original confirming an extended-period demand should test the suppression averment for this kind of particularity before addressing the substantive facts.
For GST practitioners, while this judgment does not itself decide any Section 74 question, its reasoning on what distinguishes “knowledge as a defence to the six-month clock” from “knowledge as evidence against suppression” is a useful analytical frame for parallel disputes over the extended period under Section 74 of the CGST Act — particularly where a GST demand is founded on figures from a taxpayer’s own GSTR filings, audited financials, or records produced in response to a departmental audit under Section 65 of the CGST Act. Because the judgment expressly declines to disturb the underlying merits of the demand, it also illustrates a broader litigation strategy point: a limitation defence, if it succeeds, can dispose of an appeal without requiring either side to litigate the substantive correctness of the demand at all, which may be the more efficient route in a case where the limitation facts are clear and undisputed even if the merits are contested.
5. Conclusion
Hindalco Industries confirms, on a fact pattern about as favourable to the assessee as this line of authority is likely to produce, that the extended period of limitation under Section 11A’s proviso turns on proof of a deliberate act of concealment by the assessee and not on any deficiency in the Department’s own vigilance. A demand built entirely on a statutory record the assessee was obliged to prepare and produce, concerning facts departmental officers had personally witnessed, cannot be recharacterised as one founded on suppression merely because the assessee did not additionally volunteer the information. The judgment leaves Neminath Fabrics undisturbed for cases where suppression is actually admitted or established, distinguishing rather than doubting it, and it leaves the merits of the underlying demand entirely open, having disposed of the appeal on limitation alone.
The decision’s most durable value lies less in its result on a modest sum of Rs. 6,29,920 than in the analytical structure it offers: separating the jurisdictional question of whether suppression exists from the computational question of how the extended period is measured, and insisting that departmental conduct contemporaneous with the alleged concealment be weighed as evidence on the first question even where it cannot shorten the second. Because an identically worded suppression ingredient governs the extended period for demands under Section 74 of the GST regime, this Central Excise ruling is worth reading closely by GST practitioners defending demands built on an assessee’s own filings or records — while remaining alert that no court has yet held the analogy binding, and that the CGST Act’s own developing case law must be consulted on its own terms.

FAQ
Does departmental knowledge of the underlying facts, by itself, defeat the extended period of limitation under Section 11A of the Central Excise Act? Not automatically. The Court did not hold that departmental knowledge shortens the statutory five-year period once suppression is established, since Neminath Fabrics forecloses that. It held instead that contemporaneous departmental knowledge is evidence from which the absence of suppression itself may be inferred — a different and anterior question from how the period, once triggered, is to be measured.
Can a demand invoking the extended period rest entirely on figures from the assessee’s own statutory records, such as a cost audit report? On this judgment’s reasoning, such a demand is highly vulnerable, because a document the assessee was legally bound to prepare and produce cannot simultaneously be treated as the vehicle for its own suppression. The Court held these two propositions cannot stand together.
Does this Central Excise ruling apply to GST demands invoking the extended period under Section 74 of the CGST Act? The judgment does not decide any GST question and is confined to Section 11A of the Central Excise Act, 1944. Because Section 74 of the CGST Act uses the same “fraud, wilful misstatement or suppression of facts” formulation, the reasoning is a useful analytical reference for GST practitioners, but no court has held it binding on GST adjudication, and the CGST Act’s own case law should be checked directly.
