Outcome: The appeal was dismissed for non-prosecution under Rule 20 of the Customs, Excise and Service Tax Appellate Tribunal (Procedure) Rules, 1982.

Issues: Whether the extended period of limitation could be invoked for the excise-duty demand where the relevant facts and records had been made available during audit.

Analysis: The demand covered April 2011 to November 2013, while the audit had issued a deficiency memo on 10.03.2014 based on the assessee's records. The show-cause notice was issued only on 13.04.2016 by invoking the extended period. Availability of the material records to audit did not establish suppression or any conduct justifying invocation of the extended limitation period.

Conclusion: The extended period of limitation was not invocable; the demand raised by its invocation was time-barred and was set aside in favour of the assessee.

Issues: (i) Whether recovery of central excise duty by invocation of the extended limitation period was sustainable; (ii) Whether Nicotine Sulphate was classifiable under CTH 24039990 or CTH 29399900; (iii) Whether the manufacturer and purchaser were related parties for valuation of the goods supplied to the purchaser.

Issue (i): Whether recovery of central excise duty by invocation of the extended limitation period was sustainable.

Analysis: The manufacturer had informed the department of manufacture and classification of Nicotine Sulphate under Chapter 29 and had consistently disclosed the disputed classification in monthly ER-1 returns. The disclosed material did not support an allegation of suppression or misstatement necessary to invoke the extended period.

Conclusion: The demand for June 2015 to June 2017 issued by invoking the extended limitation period was barred by limitation, in favour of the assessee.

Issue (ii): Whether Nicotine Sulphate was classifiable under CTH 24039990 or CTH 29399900.

Analysis: The manufacturing process showed that the product was a vegetable alkaloid. Heading 29.39 covers alkaloids and their derivatives, and the Chapter 29 restriction concerning separately chemically defined compounds did not exclude this product because alkaloids are an identified exception under the HSN general notes. The report relied on by Revenue concerned a sample drawn from a third-party premises without the manufacturer's representative, tested more than a year after drawal contrary to the prescribed sampling standard, and included a classification opinion beyond the chemical examiner's analytical role. Factory samples tested subsequently described the product as an aqueous solution of Nicotine Sulphate and an organic chemical.

Conclusion: Nicotine Sulphate was correctly classifiable under CTH 29399900 and not under CTH 24039990; the consequential duty, interest and penalty were unsustainable, in favour of the assessee.

Issue (iii): Whether the manufacturer and purchaser were related parties for valuation of the goods supplied to the purchaser.

Analysis: The allegation of related-party status rested on one individual being a partner of the manufacturer and managing director of the purchaser. No supporting evidence established that the entities satisfied the statutory requirements of related persons. The valuation demand based on 110% of cost of production consequently lacked foundation.

Conclusion: The entities were not established to be related parties; the differential duty, interest and penalty on this count were unsustainable, in favour of the assessee.

Final Conclusion: The extended-period demand and the related-party valuation demand fail, while the declared Chapter 29 classification of Nicotine Sulphate prevails.

Ratio Decidendi: A disclosed tariff classification cannot attract the extended limitation period absent suppression, and Nicotine Sulphate, as a vegetable alkaloid derivative, falls under the alkaloid heading notwithstanding the general requirement of separate chemical definition in Chapter 29.

Issues: Whether a demand confirmed after nearly ten years of the assessee's application under the retrospective amendment scheme could be set aside solely because verification was not completed within the prescribed two-month period.

Analysis: Section 70 of the Finance Act, 2010 required verification of the amount paid under the scheme within two months and permitted recovery of any shortfall with interest. The delay in verification and issuance of the impugned order was substantial. However, the demand was not challenged on merits, and the Tribunal lacked jurisdiction to quash the demand solely on the ground of prolonged delay, unlike the constitutional jurisdiction exercised by the High Court. The departmental delay justified relief from interest.

Conclusion: The confirmed demand was not set aside, but no interest is payable on that demand.

Issues: Whether the appellate authority could accept the assessee's claimed classification of the exported goods without requiring a fresh show cause notice or remanding the matter for fresh classification adjudication.

Analysis: The original authority had itself examined the classification, afforded the assessee an opportunity of hearing, and reclassified the goods from parts of industrial robots to parts of a grass-cutting machine. The appellate authority considered the relevant export and product material and accepted the assessee's claimed classification as parts of industrial robots. Since classification had already been adjudicated after inquiry and opportunity to the assessee, no fresh show cause notice or remand was required merely because the appellate authority disagreed with the original authority's classification.

Conclusion: The appellate authority validly accepted the assessee's claimed classification; a fresh show cause notice or remand was not necessary. The issue is decided in favour of the assessee.

Issues: Whether CENVAT credit is admissible on steel, cement, welding electrodes and gases used in fabricating structural works and support structures connected with cement and power plants for the period before 07.07.2009.

Analysis: The materials were used for fabrication of foundations, platforms, supports, conveyor structures, galleries, pipelines, chimneys and related structures required for installation and functioning of capital goods. Their eventual embedding in earth did not negate their use, directly or indirectly, in relation to manufacture. The exclusion introduced with effect from 07.07.2009 was not clarificatory or retrospective; therefore, it could not govern credit taken before that date.

Conclusion: CENVAT credit on the specified materials used for the stated structural and support works before 07.07.2009 is admissible, in favour of the assessee.

Issues: Whether an appeal against the CESTAT's determination of taxability of a service is maintainable before the High Court under Section 35G of the Central Excise Act, 1944.

Analysis: A determination of the taxability of a particular service falls within the expression "determination of any question having a relation to the rate of duty of excise". The applicable appellate forum for such determination is the Supreme Court under Section 35L of the Central Excise Act, 1944. The contrary authority did not decide the question of High Court maintainability, and no basis was established for departing from the binding Division Bench view.

Conclusion: The appeal was not maintainable before the High Court; the appropriate statutory remedy lies before the Supreme Court under Section 35L of the Central Excise Act, 1944.

Issues: Whether reimbursement recovered from a buyer for the amount reversed under Rule 6(3)(a)(i) of the Cenvat Credit Rules, 2004, though shown in the invoice's excise-duty column, constitutes an amount collected as representing excise duty under Section 11D of the Central Excise Act, 1944.

Analysis: The exempt goods carried no excise-duty liability. The statutory records and ER-1 returns established that the prescribed percentage of the value of exempt clearances had already been reversed under Rule 6(3)(a)(i). The agreement specifically provided for the buyer to reimburse that reversal, demonstrating that the payment was not intended or understood as excise duty. The invoice description could not override the transaction's real legal character. Section 11D targets retention of amounts collected by falsely representing them as excise duty; it did not apply to a reimbursement of an amount already reversed and accounted for under the Cenvat scheme.

Conclusion: The reimbursement was not collected as representing excise duty, and Section 11D of the Central Excise Act, 1944, was inapplicable.

Issues: (i) Whether the alleged shortage determined from estimated stock-taking and discrepancies between statutory records and physical stock established clandestine manufacture and removal without payment of duty; (ii) Whether the extended period of limitation, interest and penalty could be sustained.

Issue (i): Whether the alleged shortage determined from estimated stock-taking and discrepancies between statutory records and physical stock established clandestine manufacture and removal without payment of duty.

Analysis: Production of pig iron was recorded using yield-based conversion ratios because no post-production weighment system was available, while physical stock-taking was conducted by volumetric or eye estimation. Both methods were inherently approximate and could generate discrepancies. The Revenue produced no actual weighment report or independent evidence of unaccounted manufacture, removal, transport, purchasers, sale proceeds, excess raw-material consumption, or excess electricity consumption. A stock discrepancy based solely on estimation cannot establish clandestine removal.

Conclusion: The charge of clandestine manufacture and removal was not proved; the duty demand based on the alleged shortages was unsustainable, in favour of the assessee.

Issue (ii): Whether the extended period of limitation, interest and penalty could be sustained.

Analysis: The show cause notice invoked the extended period for the relevant period, but the Revenue established no mala fides, suppression, or intent to evade duty. The assessee's public-sector character and disclosure of the stock discrepancy further negated the basis for invoking the extended period. As the principal demand failed, penalty could not survive.

Conclusion: The extended-period demand was unsustainable and the penalty was liable to be set aside, in favour of the assessee.

Final Conclusion: Estimated stock variations and record discrepancies, without tangible corroborative evidence of illicit manufacture and clearance, cannot support an excise-duty liability or its penal consequences.

Ratio Decidendi: Clandestine removal cannot be inferred solely from estimated stock shortages or discrepancies in production and stock records; it requires tangible and corroborative evidence of unaccounted manufacture and clearance.

Outcome: The special leave petition was dismissed; any question of law was kept open.

Issues: Whether the extended period of limitation could be invoked to recover annual differential refund amounts taken as suo motu credit.

Analysis: The self-credit for each financial year was disclosed in monthly duty-payment statements and separately intimated to the Department through letters. The Department did not dispute entitlement to the underlying refund amounts, and all material facts concerning the availment of credit were within its knowledge. No evidence established suppression, fraud, or mala fide intent to evade duty so as to justify invocation of the extended limitation period.

Conclusion: The show cause notice invoking the extended period was barred by limitation; consequently, no demand proceedings were sustainable against the assessee.

Issues: Whether service tax paid on outward freight for dispatch of final products from the factory to customers before 01.04.2008 qualified for CENVAT credit as an input service.

Analysis: Before the amendment effective from 01.04.2008, the definition of input service covered services used directly or indirectly in relation to clearance of final products from the place of removal and expressly included outward transportation from that place. As the freight was paid by the manufacturer for dispatch from its factory premises and Revenue did not dispute that factual position, the pre-amendment definition applied. The amendment substituting "from" with "upto" the place of removal did not govern the disputed period.

Conclusion: The assessee was eligible for CENVAT credit of service tax paid on outward freight charges incurred before 01.04.2008.

Issues: (i) Whether Cenvat credit was admissible on services used for fabrication, erection of pipelines, welding, cutting and flange fixing for setting up the factory after 01.04.2011; (ii) Whether the extended limitation period and penalty were invocable on the ground of suppression.

Issue (i): Whether Cenvat credit was admissible on services used for fabrication, erection of pipelines, welding, cutting and flange fixing for setting up the factory after 01.04.2011.

Analysis: Rule 2(l) covers services used directly or indirectly in or in relation to manufacture. Although the post-01.04.2011 inclusive portion no longer expressly refers to setting up, services used for establishing the factory remain covered by the main part where they have a direct nexus with manufacture, unless specifically excluded. The disputed services were not construction of a building or civil structure within the exclusion and were necessary to establish the manufacturing facility.

Conclusion: The disputed setting-up services qualified as input services and the Cenvat credit was validly availed and utilised, in favour of the assessee.

Issue (ii): Whether the extended limitation period and penalty were invocable on the ground of suppression.

Analysis: The credit formed part of the total credit disclosed in the monthly returns, and there was no legal requirement to separately disclose the nature of each service or the credit attributable to it. Non-disclosure of information not required by law could not constitute suppression or wilful misstatement. Since the credit was admissible, no intent to evade duty could be inferred.

Conclusion: The extended period was not invocable and no penalty was leviable, in favour of the assessee.

Final Conclusion: The recovery of credit, interest and penalty could not be sustained because the services had the requisite nexus with manufacture and the conditions for alleging suppression were absent.

Ratio Decidendi: Post-01.04.2011, services necessary for setting up a factory qualify as input services under the main limb of Rule 2(l) where directly connected with manufacture and not specifically excluded; absence of a statutory duty to separately disclose service-wise credit precludes an allegation of suppression.

Issues: (i) Whether CENVAT credit on capital goods installed in a captive power plant was admissible where electricity was substantially captively consumed in manufacture of dutiable goods and only surplus electricity was supplied outside the factory; (ii) Whether full CENVAT credit on specified input services under Rule 6(5) was admissible in the same circumstances; (iii) Whether CENVAT credit on iron and steel items used for repair and maintenance of existing plant and machinery was admissible; (iv) Whether duty on clearance of waste and scrap arising from capital goods was sustainable under Rule 3(5).

Issue (i): Whether CENVAT credit on capital goods installed in a captive power plant was admissible where electricity was substantially captively consumed in manufacture of dutiable goods and only surplus electricity was supplied outside the factory.

Analysis: Rule 6(4) bars credit only where capital goods are used exclusively in manufacture of exempted goods or provision of exempted services. The captive power plant formed an integral part of the manufacturing unit, and electricity generated from it was substantially used in manufacturing dutiable products. Supply of surplus electricity outside the factory did not establish exclusive use of the capital goods for exempted output. The input-credit nexus principle applicable to inputs did not displace the distinct exclusive-use standard governing capital goods. The applicable Board circular also supported credit where exempt intermediate goods are captively consumed in manufacture of dutiable final products.

Conclusion: CENVAT credit on the capital goods was admissible; this issue is decided in favour of the assessee.

Issue (ii): Whether full CENVAT credit on specified input services under Rule 6(5) was admissible in the same circumstances.

Analysis: Rule 6(5) allowed full credit on specified common taxable services unless they were used exclusively in relation to exempted goods or exempted services. The services were not exclusively used for electricity supplied outside the factory, since the electricity was substantially consumed in producing dutiable final products. The Board clarification regarding the treatment of specified common services reinforced this interpretation.

Conclusion: CENVAT credit on the specified input services was admissible; this issue is decided in favour of the assessee.

Issue (iii): Whether CENVAT credit on iron and steel items used for repair and maintenance of existing plant and machinery was admissible.

Analysis: Eligibility depended on the actual use of the iron and steel items rather than their description alone. The factual finding that the items were used for repair and maintenance of existing manufacturing plant and machinery, and not for civil construction or fabrication of immovable supporting structures, was neither perverse nor unsupported by evidence. Such factual findings could not be reappreciated in an appeal confined to substantial questions of law.

Conclusion: CENVAT credit on the iron and steel items was admissible; this issue is decided in favour of the assessee.

Issue (iv): Whether duty on clearance of waste and scrap arising from capital goods was sustainable under Rule 3(5).

Analysis: The Revenue did not identify any statutory infirmity or evidentiary basis showing that the Tribunal's factual finding setting aside the demand was perverse or contrary to the CENVAT Credit Rules. A challenge seeking reassessment of factual conclusions did not raise a substantial question of law under Section 35G.

Conclusion: The demand of duty on waste and scrap was unsustainable; this issue is decided in favour of the assessee.

Final Conclusion: The Tribunal's determinations on CENVAT eligibility and the waste-and-scrap demand were sustained, and all substantial questions of law were answered against the Revenue.

Ratio Decidendi: Where capital goods or specified input services are not used exclusively for exempted output because they form part of an integrated process producing dutiable final goods, Rules 6(4) and 6(5) do not bar CENVAT credit merely because surplus electricity is supplied outside the factory.

Issues: Whether an appeal could be decided ex parte on a date for which the appellant received no notice after the previously fixed hearing date could not be held because no two-member Bench sat.

Analysis: Rule 18(1) required the Tribunal to notify the parties of the date and place of hearing. The dispensation of individual adjournment notices under Public Notice No. 3/2019 operated through uploading judicial orders that disclosed the adjourned date. No two-member Bench sat on the scheduled date, no judicial order was passed or uploaded fixing the later hearing date, and the non-sitting could not constitute an adjournment under Rule 24. The appellant was therefore entitled to fresh notice of the next hearing date; requiring it to discover that date from weekly cause lists imposed an unsupported degree of diligence.

Conclusion: The question was answered in the negative, in favour of the assessee and against the Revenue; the ex parte order was made without due opportunity of hearing.

Issues: Whether the Tribunal's full remand for fresh adjudication, owing to denial of effective cross-examination and non-consideration of material submissions, gave rise to a substantial question of law.

Analysis: The Tribunal found that statements relied upon in the adjudication had not been tested in accordance with Section 9D, and that cross-examination of several requested witnesses was denied on the erroneous premise that unretracted statements did not require cross-examination. It also found that cross-examination allowed for certain witnesses was substantially not conducted. Further, the adjudicating authority had failed to address the material explanation concerning procurement of packing material by other franchisees manufacturing the same branded goods. These deficiencies constituted breach of principles of natural justice and required a full fresh adjudication.

Conclusion: The remand order was unobjectionable and raised no substantial question of law; the finding is in favour of the assessee.

Issues: Whether the Appellate Tribunal could restore an appeal dismissed for the appellant's default upon a restoration application establishing sufficient cause for non-appearance.

Analysis: Rule 20 of the Customs, Excise and Service Tax Appellate Tribunal (Procedure) Rules, 1982 permits dismissal for default where the appellant is absent, but its proviso requires the Tribunal to set aside that dismissal and restore the appeal where the appellant subsequently satisfies it that sufficient cause existed for the non-appearance. The Tribunal therefore had statutory power, coupled with an obligation upon proof of sufficient cause, to consider the restoration request; it could not reject the application solely on the premise that restoration would amount to reviewing its own order.

Conclusion: The Tribunal has jurisdiction to consider and, on sufficient cause being established, restore an appeal dismissed for default. The issue is decided in favour of the assessee.

Issues: (i) Whether the departmental appeal was barred from the High Court's jurisdiction because excisability was connected with the rate of duty; (ii) Whether revenue neutrality was established through entitlement to CENVAT credit for additional customs duty debited through DEPB scrips; (iii) Whether the extended period of limitation was invocable; (iv) Whether penalty and interest were sustainable.

Issue (i): Whether the departmental appeal was barred from the High Court's jurisdiction because excisability was connected with the rate of duty.

Analysis: The assessee had raised manufacture and excisability before the original authority but confined its Tribunal challenge to revenue neutrality. The finding that the activity amounted to manufacture and the goods were excisable was consequently left unchallenged and attained finality. The surviving controversy concerned revenue neutrality and did not attract the statutory exclusion relating to determination of rate of duty.

Conclusion: The appeal before the High Court was maintainable, in favour of the Revenue.

Issue (ii): Whether revenue neutrality was established through entitlement to CENVAT credit for additional customs duty debited through DEPB scrips.

Analysis: For the period up to 31.08.2004, CENVAT credit was unavailable where additional customs duty was discharged merely by debit of DEPB scrips rather than in cash; use of the scrip extinguished its value. For the subsequent period, although policy changes could permit such credit, revenue neutrality required a factual determination of the quantum of admissible credit. The Tribunal recorded that credit exceeded duty without identifying supporting material. The assessee, having invoked revenue neutrality, bore the burden to establish the available credit and its sufficiency to offset the duty demand.

Conclusion: Revenue neutrality was not established, in favour of the Revenue.

Issue (iii): Whether the extended period of limitation was invocable.

Analysis: The original authority had recorded findings of deliberate suppression of the manufacturing activity with intent to evade duty and rejected the asserted bona fide belief. The Tribunal treated the prior demand as time-barred without reasons sufficient to displace those factual findings.

Conclusion: Invocation of the extended period of limitation was valid, in favour of the Revenue.

Issue (iv): Whether penalty and interest were sustainable.

Analysis: The original authority's findings established contraventions of the Central Excise Rules and positive conduct intended to evade excise duty. No perversity was shown in the factual basis for the statutory penalty and interest.

Conclusion: Penalty and interest were sustainable, in favour of the Revenue.

Final Conclusion: The Tribunal's acceptance of revenue neutrality and its limitation finding could not stand; the original duty, interest and penalty consequences were restored.

Ratio Decidendi: Revenue neutrality can defeat an excise demand only upon proof, by the assessee, of admissible credit sufficient to offset the duty liability; an unsupported assertion of credit cannot sustain that plea.

Issues: Whether the Revenue appeal concerning conditional refund/credit affected by the settled validity challenge to Notifications No. 19/2008 and 34/2008, and refund relating to alleged fictitious clearances, survived for adjudication.

Outcome: The appeal was disposed of as it did not survive; Revenue may take action in accordance with the applicable Supreme Court decision and pending show-cause proceedings.
