Issues: (i) Whether duty under Rule 6 of the Central Excise Valuation (Determination of Price of Excisable Goods) Rules, 2000 is to be computed on the total sale value or the amortised value of tools, dies and moulds separately sold to customers and used in manufacturing final products; (ii) Whether the captive consumption exemption under Notification No. 67/95-CE applies to tools, dies and moulds separately sold to customers and thereafter used in manufacture; (iii) Whether the extended period of limitation, interest and penalty are sustainable.

Issue (i): Whether duty under Rule 6 of the Central Excise Valuation (Determination of Price of Excisable Goods) Rules, 2000 is to be computed on the total sale value or the amortised value of tools, dies and moulds separately sold to customers and used in manufacturing final products.

Analysis: Tools and dies are used repeatedly for producing final goods; their cost must consequently be spread over the goods produced through amortisation. The appellant had adopted this method where the tooling was customer-supplied, and the same method applies where the tooling was manufactured or procured by the appellant and separately invoiced to customers.

Conclusion: Only the amortised value of the tools, dies and moulds is includible in the assessable value of the final products. This issue is decided in favour of the assessee.

Issue (ii): Whether the captive consumption exemption under Notification No. 67/95-CE applies to tools, dies and moulds separately sold to customers and thereafter used in manufacture.

Analysis: The captive consumption exemption applies where goods are not sold and their value is absorbed in the value of the final products. Tools and dies sold to customers under separate invoices and thereafter used in manufacture stand on the same footing as tooling supplied by customers and do not qualify for that exemption.

Conclusion: The captive consumption exemption is unavailable. This issue is decided against the assessee.

Issue (iii): Whether the extended period of limitation, interest and penalty are sustainable.

Analysis: The appellant had included amortised tooling value in comparable cases involving customer-supplied tools and dies. Its omission to include such value for tooling separately sold to customers could not therefore be attributed to a bona fide belief.

Conclusion: The extended period of limitation is invocable; interest and penalty are consequently sustainable, subject to recalculation. This issue is decided against the assessee.

Final Conclusion: The duty liability must be recalculated by adopting the amortised tooling value in the assessable value of the final products, with corresponding recalculation of interest and penalty; the claims to captive-use exemption and limitation protection fail.

Ratio Decidendi: Where tools, dies or moulds sold to customers are subsequently used in manufacture, their amortised value must be included in the assessable value of the final products, and such tooling does not qualify for captive consumption exemption.

Issues: Whether CENVAT credit is admissible on additional customs duty (CVD) paid at the concessional rate of 2% on imported coal under Notification No. 12/2012-Customs dated 17.03.2012.

Analysis: Section 3(1) of the Customs Tariff Act, 1975 provides for CVD corresponding to excise duty, while Rule 3(1)(vii) of the Cenvat Credit Rules, 2004 permits credit of such additional duty. The concessional 2% CVD rate was prescribed in public interest under Section 25(1) of the Customs Act, 1962. That notified rate remains equivalent to the excise-duty component for purposes of Rule 3(1)(vii); the restriction concerning exemptions under the Central Excise notifications does not govern CVD paid under the Customs notification.

Conclusion: CENVAT credit of the 2% CVD paid on imported coal under Notification No. 12/2012-Customs dated 17.03.2012 is admissible, in favour of the assessee.

Issues: Whether the adjudication and appellate orders, passed after remand, could disregard the Tribunal's directions to reconsider classification, valuation and extended-period demand with reference to the technical material and approved classifications.

Analysis: The adjudicating authority expressed a view contrary to the Tribunal's remand directions while dealing with the evidentiary role of technical reports, notwithstanding the specific requirement to consider such material for redetermination of classification. The appellate order reproduced and confirmed that approach, disclosing the same infirmity and non-application of mind. The remand directions of the statutory appellate forum were required to be followed in the fresh adjudication.

Conclusion: The orders passed in disregard of the Tribunal's remand directions were invalid; the matter must be freshly adjudicated in accordance with those directions after affording hearing to the assessee.

Issues: Whether central excise duty and penalty for alleged clandestine clearances could be sustained where the seized records forming the basis of the demand were unreliable and the remaining turnover fell within the small scale industry exemption limit.

Analysis: The panchnama and the documents allegedly seized under it were not reliable because the material records were not produced, their contents were not established, and the evidence of the panch witness and the officer preparing the panchnama was contradictory regarding the timing of its execution. The Neel Gagan Ledger and other documents relied upon for quantification were neither supplied nor established as recovered records. The proprietor's statement was not inculpatory, as it recorded that the entries were rough, their author was unknown, and copies were not furnished. On excluding clearance values based on the unreliable ledger and documents, the turnover for both 2008-09 and 2009-10 remained within the exemption threshold under the notification.

Conclusion: The alleged clandestine clearances were not proved by reliable evidence; no duty or penalty was payable, as the turnover for both years was within the small scale industry exemption limit.

Issues: (i) Whether denial of exemption under Notification No. 12/2012-CE on the ground of alleged non-fulfilment of conditions under Notification No. 12/2012-Cus is legally sustainable? (ii) Whether the consequential duty demand, interest and penalties confirmed under the impugned order are sustainable in law?

Issue (i): Whether denial of exemption under Notification No. 12/2012-CE on the ground of alleged non-fulfilment of conditions under Notification No. 12/2012-Cus is legally sustainable?

Analysis: Serial No. 336 of the central excise notification grants exemption to supplies under International Competitive Bidding subject to Condition No. 41, which imports applicable customs conditions mutatis mutandis. That expression incorporates only conditions capable of application to domestic clearances, and does not mechanically transplant import-specific procedural requirements onto an indigenous manufacturer. The eligible project, actual end use, and authenticity of the Project Authority Certificate were undisputed. As the substantive eligibility requirements were fulfilled, procedural requirements framed for import transactions could not defeat the exemption or the object of preserving parity between imported and domestically manufactured goods.

Conclusion: Denial of the exemption was legally unsustainable and the assessee was entitled to the exemption.

Issue (ii): Whether the consequential duty demand, interest and penalties confirmed under the impugned order are sustainable in law?

Analysis: The duty demand was wholly derivative of the denial of exemption. Payment under protest could not validate an unsustainable demand. Interest under Section 11AA presupposes a legally recoverable principal duty liability. Further, the clearances were made under the claimed exemption after prior intimation and production of the Project Authority Certificate; in the absence of suppression or clandestine removal, and where the dispute was interpretational, penalties under Rule 25 were not attracted.

Conclusion: The duty demand, consequential interest, and penalties were unsustainable and were required to be set aside in full, in favour of the assessee.

Final Conclusion: The eligible International Competitive Bidding supplies remained exempt, with no surviving central excise duty, interest, or penal liability.

Ratio Decidendi: A mutatis mutandis incorporation of customs-notification conditions into an excise exemption applies only conditions capable of operation for domestic supplies; import-specific procedural requirements cannot override undisputed substantive eligibility for exemption.

Issues: (i) Whether the appellant is entitled to avail CENVAT credit of CVD paid on capital goods imported by CECL, a separate legal entity? (ii) Whether the confirmation of demand of Rs. 8,13,91,044/- together with interest and penalty under the impugned order is legally sustainable in law?

Issue (i): Whether the appellant is entitled to avail CENVAT credit of CVD paid on capital goods imported by CECL, a separate legal entity?

Analysis: Under Rules 3(1) and 4(3) of the CENVAT Credit Rules, 2004, credit is available only to the legally eligible manufacturer or service provider in the statutorily prescribed manner. CECL imported the capital goods, paid the CVD, held the Bills of Entry, and owned the power plant. Majority shareholding, captive consumption of electricity, and economic integration do not extinguish CECL's separate juristic personality or transfer its statutory credit entitlement to the appellant. The Rules do not permit cross-entity availment of credit merely on functional nexus, revenue neutrality, or commercial convenience.

Conclusion: The appellant was not entitled to avail CENVAT credit of CVD paid on capital goods imported by CECL. The issue is decided against the assessee.

Issue (ii): Whether the confirmation of demand of Rs. 8,13,91,044/- together with interest and penalty under the impugned order is legally sustainable in law?

Analysis: Since the disputed credit was inadmissible, its recovery follows under Rule 14 of the CENVAT Credit Rules, 2004 read with Section 11A of the Central Excise Act, 1944. Revenue neutrality cannot validate credit availed without statutory authority. Statutory interest follows the wrongful availment, and the equal penalty under Rule 15(2) of the CENVAT Credit Rules, 2004 read with Section 11AC of the Central Excise Act, 1944 was sustained on the facts.

Conclusion: The demand of Rs. 8,13,91,044/-, with applicable interest and equal penalty, is legally sustainable. The issue is decided against the assessee.

Final Conclusion: CENVAT credit linked to duty paid on imported capital goods remains available only to the legally entitled importing entity and cannot be claimed by a distinct corporate entity on the basis of captive use or common economic control.

Ratio Decidendi: Statutory CENVAT credit cannot be transferred between separate corporate entities absent an express statutory mechanism, notwithstanding their shareholding relationship, economic integration, or captive business arrangement.

Issues: (i) Whether rejection of the claim for interest on sanctioned refund on grounds of delay and laches under the Limitation Act, 1963 was sustainable; (ii) Whether the duty payments and contemporaneous electronic refund claims were voluntary payments at the assessee's peril or payments under protest made with departmental knowledge; (iii) Whether the contemporaneous electronic claims or the subsequent Form R claim constituted the application under Section 11B(1) of the Central Excise Act, 1944 for reckoning the three-month period under Section 11BB; and (iv) Whether interest under Section 11BB was payable on the sanctioned refunds and, if so, for what period.

Issue (i): Whether rejection of the claim for interest on sanctioned refund on grounds of delay and laches under the Limitation Act, 1963 was sustainable.

Analysis: Section 11BB of the Central Excise Act, 1944 imposes an automatic and self-executing obligation to pay interest where refund is delayed beyond three months. A request for such interest merely invokes that statutory obligation and does not institute a fresh, time-barred cause of action. Failure to appeal the refund sanction orders or to file cross-objections could not defeat the entitlement where those orders contained no determination on interest. The departmental appeal against the principal refund also remained pending for part of the period treated as delay.

Conclusion: Rejection of interest on grounds of limitation, delay and laches was unsustainable and is set aside in favour of the assessee.

Issue (ii): Whether the duty payments and contemporaneous electronic refund claims were voluntary payments at the assessee's peril or payments under protest made with departmental knowledge.

Analysis: The interim restraint operated against the Department and did not prohibit payment of duty under protest, a course protected by the second proviso to Section 11B(1) of the Central Excise Act, 1944. The Department accepted the registration, protest payments and electronic claims over several years without objection, reservation or recourse to the High Court. It could not subsequently rely on its own inaction to characterize the payments as voluntary.

Conclusion: The payments and contemporaneous electronic claims were made under protest with departmental knowledge, not voluntarily at the assessee's peril; the contrary finding is set aside in favour of the assessee.

Issue (iii): Whether the contemporaneous electronic claims or the subsequent Form R claim constituted the application under Section 11B(1) of the Central Excise Act, 1944 for reckoning the three-month period under Section 11BB.

Analysis: The second proviso to Section 11B(1) recognizes refund claims relating to duty paid under protest while the underlying levy remains disputed. Section 11BB measures interest from receipt of the application under Section 11B(1), and the relevant-date definition in Clause (ec) of Explanation (B) to Section 11B governs only the limitation for filing a refund application, not postponement of interest. The electronically filed claims were received without deficiency memo or objection; the later physical Form R filing was only an administrative reiteration of claims already on record.

Conclusion: The contemporaneous electronic claims constituted the applications under Section 11B(1) for computing interest under Section 11BB; Form R was only a physical reiteration of those claims, in favour of the assessee.

Issue (iv): Whether interest under Section 11BB was payable on the sanctioned refunds and, if so, for what period.

Analysis: Since the refunds corresponded to the amounts paid and claimed under protest, there was no unascertained quantification preventing the running of interest. Interest must run after expiry of three months from receipt of each corresponding electronic claim until the date on which the refund was actually sanctioned. Exact dates of receipt require verification from departmental records.

Conclusion: The assessee is entitled to interest under Section 11BB from the day following expiry of three months from receipt of each electronic claim until 05.05.2015, subject to verification and quantification by the refund sanctioning authority.

Final Conclusion: The orders denying statutory interest are displaced, and the matter is returned solely for verification of the electronic-claim receipt dates and calculation and sanction of the consequential interest in accordance with natural justice.

Ratio Decidendi: Interest under Section 11BB on refund of duty paid under protest runs from expiry of three months after receipt of the valid refund application, and cannot be postponed to a subsequent judicial determination or physical reiteration of an unobjected electronic claim.

Issues: (i) Whether an appeal under Section 35G against a procedural implementation direction issued under Rule 41 was maintainable, and whether the Tribunal exceeded its jurisdiction by issuing that direction; (ii) Whether service tax paid on the drinking-water project was a payment under mistake of law, disentitling the Revenue from invoking the limitations applicable to duty refunds; (iii) Whether interest on the refund was payable from three months after the original refund applications rather than from submission of subsequent administrative documents; (iv) Whether compensatory interest at 9% was valid notwithstanding Notification No. 24/2014-C.E. (N.T.).

Issue (i): Whether an appeal under Section 35G against a procedural implementation direction issued under Rule 41 was maintainable, and whether the Tribunal exceeded its jurisdiction by issuing that direction.

Analysis: Section 35G permits an appeal only from an order passed by the Tribunal in appeal under Sections 35B and 35C. A direction under Rule 41 to implement an earlier final order is procedural and connected with securing the ends of justice; it is not an order passed in appeal. Rule 41 validly enabled consequential directions necessary to ensure that the final refund order was effective.

Conclusion: The appeal under Section 35G was not maintainable, and the Tribunal acted within its jurisdiction in issuing the Rule 41 direction, in favour of the assessee.

Issue (ii): Whether service tax paid on the drinking-water project was a payment under mistake of law, disentitling the Revenue from invoking the limitations applicable to duty refunds.

Analysis: Laying potable-water pipelines for a statutory water authority under a public-welfare project did not constitute taxable commercial or industrial construction service. The amount paid consequently lacked the character of tax or duty and was paid under a mistake of law. Such collection is inconsistent with Article 265, and the restrictive procedural limitations applicable to duty refunds under Section 11B do not govern its restitution.

Conclusion: The payment was made under a mistake of law and was refundable without application of the restrictive limitation framework for duty refunds, in favour of the assessee.

Issue (iii): Whether interest on the refund was payable from three months after the original refund applications rather than from submission of subsequent administrative documents.

Analysis: Liability for interest under Section 11BB commences automatically on expiry of three months from receipt of the original refund application, not from an appellate order or a later implementation request. The later communication and documents were follow-up material for implementing the original claims and did not constitute fresh refund applications.

Conclusion: Interest was payable from expiry of three months after the original 2012 refund applications, in favour of the assessee.

Issue (iv): Whether compensatory interest at 9% was valid notwithstanding Notification No. 24/2014-C.E. (N.T.).

Analysis: Since the refundable amount was paid under a mistake of law and did not bear the character of duty, the statutory 6% rate under the notification did not restrict the compensatory interest payable. The prolonged withholding of the amount justified the 9% rate awarded for compensation.

Conclusion: Compensatory interest at 9% was valid and was not contrary to Notification No. 24/2014-C.E. (N.T.), in favour of the assessee.

Final Conclusion: The Tribunal's implementation direction for refund interest remained legally effective, with the assessee entitled to restitution and compensatory interest calculated from the original refund claims.

Ratio Decidendi: A procedural direction under Rule 41 for implementation of a final Tribunal order is not appealable under Section 35G, and interest on a refund claim accrues from expiry of three months after the original application where the delayed refund arises from a payment made under mistake of law.

Issues: (i) Whether Cenvat credit could be denied despite the departmental verification report and records establishing receipt and use of duty-paid inputs; and (ii) Whether incomplete supplier addresses on invoices justified denial of Cenvat credit.

Issue (i): Whether Cenvat credit could be denied despite the departmental verification report and records establishing receipt and use of duty-paid inputs.

Analysis: The departmental verification report recorded party-wise receipt of goods and payment of duty under the relevant invoices. The appellant's purchase and clearance records further corroborated receipt and consumption of inputs. No contrary departmental evidence was produced. The evidentiary burden was discharged, demonstrating substantive compliance with the requirements for Cenvat credit.

Conclusion: The issue was decided in favour of the assessee; Cenvat credit could not be denied where receipt and use of duty-paid inputs stood established.

Issue (ii): Whether incomplete supplier addresses on invoices justified denial of Cenvat credit.

Analysis: Incomplete address particulars on invoices constituted a procedural lapse. Since duty payment, receipt of inputs, and their use in manufacture were established, the deficiency did not impair the assessee's substantive entitlement to credit under Rule 9(2) of the Cenvat Credit Rules, 2004.

Conclusion: The issue was decided in favour of the assessee; incomplete supplier addresses on otherwise accepted invoices did not justify denial of Cenvat credit.

Final Conclusion: The evidentiary record established eligibility for the disputed Cenvat credit, and the invoice defect did not defeat that entitlement.

Ratio Decidendi: Cenvat credit cannot be denied for procedural deficiencies in invoices where reliable verification and contemporaneous records establish actual receipt and use of duty-paid inputs.

Issues: Whether the manufacture of 10 kg tin containers by the independently registered job worker could be attributed to the assessee for levy of central excise duty.

Analysis: The job worker held central excise registration for manufacture and home clearance of containers and had paid excise duty. Its status as an independent manufacturer had thus been recognised for statutory purposes. In the absence of admissible evidence of financial flow-back, profit sharing, common funding, or other indicia establishing that the job worker was a dummy unit, its manufacturing activity could not be treated as that of the assessee. Where transactions with the job worker are on a principal-to-principal basis, the job worker's manufacturing cost cannot be added to the value of goods manufactured by the assessee.

Conclusion: Manufacture of the tin containers was not attributable to the assessee; the related excise-duty demands were unsustainable, in favour of the assessee.

Issues: Whether statutory interest on a refund is payable from the expiry of three months from the original refund application, or only from the subsequent appellate order or a later communication treated as a fresh refund claim.

Analysis: Section 11BB of the Central Excise Act, 1944 makes interest payable where a refundable amount is not paid within three months of receipt of the application under Section 11B. The deeming fiction concerning an appellate or court order granting refund does not postpone the commencement of interest. Section 83 of the Finance Act, 1994 applies this refund mechanism to the relevant service-tax claim. The original application was filed on 20 May 2015, and the later communication was merely a continuation or reminder of that claim, not a fresh application.

Conclusion: Statutory interest was payable to the assessee from 20 August 2015, being the expiry of three months from the original refund application, until the date of actual refund; the denial of such interest was unsustainable.

Issues: Whether recovery of CENVAT credit for March 2007 to November 2008 under a show-cause notice issued on 30.11.2010 was barred by limitation.

Analysis: The extended limitation period under Section 11A of the Central Excise Act, 1944 required fraud, collusion, wilful misstatement or suppression of facts with intent to evade duty. The department was aware of the receipt of left-over bulk cement in the factory and had issued permission for availment of credit on that quantity. No evidence established fraud, suppression of facts, or intent to evade duty. Consequently, the notice was required to be issued within the normal limitation period of one year.

Conclusion: The CENVAT credit demand was time-barred and the limitation issue was decided in favour of the assessee.

Issues: Whether the High Court had jurisdiction under Section 35G to entertain the Department's appeal concerning liability to Clean Environment Cess on closing stock.

Analysis: Section 35G excludes appeals involving determination of a question relating to the rate of excise duty or value for assessment. Section 35L(2) expressly includes within determination relating to the rate of duty a determination concerning taxability or excisability. The cess-liability question therefore falls within the appellate jurisdiction of the Supreme Court.

Conclusion: The appeal was required to be preferred before the Supreme Court under Section 35L(2) of the Central Excise Act, 1944, and was not maintainable before the High Court.

Issues: Whether distributors of excisable goods could be subjected to penalty for the manufacturer's alleged non-payment of central excise duty.

Analysis: Rule 26 of the Central Excise Rules, 2002 requires proof that the person dealt with goods and knew that the goods were liable to confiscation. The material did not establish the alleged ownership of the manufacturer by the distributors or their knowledge of any duty default. A distributor or subsequent purchaser has no legal obligation to verify proper payment of duty at the manufacturer's end; the duty liability rests upon the manufacturer.

Conclusion: The penalties imposed on the distributors under Rule 26 were unsustainable and were decided in favour of the assessees.

Issues: Whether CENVAT credit is admissible on 1%/2% additional duty of customs paid on imported steam coal under a Customs exemption notification, notwithstanding restrictions applicable to specified Central Excise exemptions.

Analysis: Rule 3(1)(vii) of the CENVAT Credit Rules, 2004 expressly permits credit of additional duty leviable under Section 3 of the Customs Tariff Act, 1975. The restriction in the proviso to Rule 3(1)(i) is confined to duty of excise paid under specified Central Excise exemption notifications and does not extend to additional duty of customs. The applicable Customs notification contained no condition prohibiting credit, and conditions from Central Excise notifications cannot be implied into or superimposed upon a Customs notification. The consistent coordinate-bench view on this issue was followed in accordance with judicial discipline and certainty.

Conclusion: CENVAT credit of the 1%/2% additional duty of customs paid on imported steam coal is admissible; denial of such credit by importing Central Excise notification restrictions is unsustainable. The issue is decided in favour of the assessee.

Issues: Whether differential central excise duty at the higher rate was payable on SKO intermingled with HSD/MS during pipeline transfer.

Analysis: The settled position applicable to identical interface-SKO clearances was adopted. Intermixing SKO with HSD/MS did not amount to manufacture under Section 2(f) of the Central Excise Act, 1944, since the goods were not specified in the Third Schedule to the Central Excise Tariff Act, 1985. Further, a departmental circular unsupported by statutory provisions could not impose duty by applying the HSD/MS rate to SKO, and a finding of manufacture could not be sustained where that basis was absent from the show-cause notice.

Conclusion: The higher differential duty demand on intermingled SKO was unsustainable, in favour of the assessee.

Issues: Whether the appellant was liable to penalty for abetting clandestine removal of excisable goods under Rule 26 of the Central Excise Rules, 2002.

Analysis: The opportunity to examine and cross-examine the persons whose statements were relied upon had been afforded after remand, and the appellant could not claim a breach of natural justice after not availing it. However, the seized diary and notepad established only their recovery, not the truth of their contents. The proceedings against the alleged manufacturer had been set aside, and the Department produced no affirmative evidence of unaccounted manufacture, procurement of raw materials, transport and clearance of goods, identified buyers, or flow of unaccounted consideration. The allegation of clandestine removal consequently lacked tangible corroboration.

Conclusion: The goods allegedly purchased by the appellant were not proved to be liable to confiscation; therefore, penalty under Rule 26 of the Central Excise Rules, 2002 was not imposable.

Issues: Whether notices of personal hearing were served upon the appellant so as to afford a valid opportunity of hearing under Section 35A(3) of the Central Excise Act, 1944.

Analysis: Issuance of hearing notices, without any acknowledgement or other material proving their service, did not establish service upon the appellant. The appellant's appearance through counsel before the same appellate authority in another matter between the same parties on the same date corroborated that it had not received notice in this matter. The Tribunal decided the interest dispute on merits without addressing the appellant's challenge to the denial of hearing.

Conclusion: The hearing notices were not served and the appellant was denied an opportunity of hearing. The appellant's claim is to be reconsidered afresh by the Commissioner (Appeals).

Issues: Whether sales tax subsidy received under the Rajasthan Investment Promotion Scheme, 2010, through VAT/CST challans, is includible in the assessable value of excisable goods.

Analysis: The assessee paid the entire VAT/CST collected from customers to the State exchequer. The subsidy was subsequently sanctioned as VAT challans for discharge of future VAT/CST liability and did not reduce the sale price or amount to retention of tax collected. Such subsidy was not an additional consideration for the sale and could not form part of transaction value under Section 4(3)(d) of the Central Excise Act.

Conclusion: The sales tax subsidy is not includible in the assessable value; no excise duty or penalty is payable by the assessee.

Issues: Whether the assessee was entitled to refund of service tax paid pursuant to a demand that was subsequently set aside, in view of the doctrine of unjust enrichment.

Analysis: Refund under Section 11B of the Central Excise Act, 1944 is conditional upon the claimant establishing that the burden of duty was not passed on to another person. The auditor's certificate was relevant evidence, but its contents showed that Rs. 9,09,717 had already been recovered from members, whereas Rs. 6,41,369 remained uncollected. The duty incidence stood passed on only to the extent of the amount recovered from members.

Conclusion: The assessee is entitled to refund of Rs. 6,41,369, being the portion for which the duty burden had not been passed on, together with applicable interest under Section 11BB of the Central Excise Act, 1944.
