JUDGMENT K. N. SAIKIA, J. :— This appeal by Special Leave is from the judgment and Order of the High Court of Judicature at Madras, dated 19th July, 1972 in Writ Petition No. 1864 of 1967, allowing the petition and quashing the demand made by the appellant under R. 10-A of the Central Excise Rules, hereinafter referred to as the Rules, payable by the respondent under the Central Excises and Salt Act, 1944, hereinafter referred to as the Act. 2. M/s. Ramakrishnan Kulwant Rai, the respondent firm, owned the Steel Rolling Mill, located at No. 4-B, 4-C, North Railway Terminus Road, Rayapuram, Madras-13. The said Mill was leased out to a partnership firm known as M/s. Steel Industries. After termination of the lease the respondent firm took back possession of the said Mill on 1-8-1962 and informed the Central Excise Authorities about this by their letter dated 16-11-1962 and resumed manufacture of Steel from scraps and was advised to take out a licence for which it applied on 30-11-1962. Though the respondent firm had ultimately sold away the Rolling Mill on 8-4-1963, the Superintendent of Central Excise, by his letter dated 13-10-1965 demanded a sum of Rs. 31,018.20p as excise duty. On information furnished by the firm about its manufacture of only 775.455 metric tonnes of Steel, the Deputy Superintendent of Central Excise reduced the demand to a sum of Rs. 6,419.38p only, and the demand was reiterated by notice dated 13-4-1967, pursuant where to the respondent firm showed cause on 15th May, 1967 but the Assistant Collector of Customs, by his order dated l4th June, 1967, confirmed the demand. 3. The respondent firm challenged the demand by moving writ petition No. 1864 of 1967 in the High Court of Judicature at Madras contending, inter alia, that it was manufacturing steel products prior to 13-6-1962, only suspending manufacture during the period of lease and resuming thereafter, and as such, was entitled to exemption from payment of duty; that the demand for payment of duty was time barred; that Rr. 10 & 10-A invoked in support of the demand were ultra vires inasmuch as there was no provision in the Act to enable the Government to frame rules for the recovery of duty short-levied. 4. The High Court by the impugned order following its earlier judgment in writ petition Nos. 10 & 10-A invoked in support of the demand were ultra vires inasmuch as there was no provision in the Act to enable the Government to frame rules for the recovery of duty short-levied. 4. The High Court by the impugned order following its earlier judgment in writ petition Nos. 265 & 266 of 1967, which relied upon its earlier decision in writ petition No. 1055 of 1968, upheld the contention of the respondent firm holding that R. 10-A did not apply to cases where there had been no prior levy of excise duty in respect of the articles manufactured during the relevant period and that the duty was sought to be recovered only by the issue of demand under R. 10-A of the Rules. The High Court having rejected leave to appeal, the appellant obtained special leave on 23-7-1974. 5. Mr. Anil Dev Singh, learned counsel for the appellant submits that it is necessary to decide the substantial question of law of general importance, namely, whether R. 10 A of the Rules, as it stood at the relevant time, was valid or not as conflicting decisions have been creating difficulties for the department in collecting short-levies or escaped excise duties. Counsel refers us to (1972) 2 Mad LJ 476. The learned counsel states that R. 10-A was in force up to 6-8-1977 where after it was amended with effect from that date and the amended rule continued till 16-11-1980 whereafter it was enacted as S. 11 A of the Act by the Amendment Act 25 of 1978 and that Section came into force with effect from 17-11-1980. 6. Mr. Ambrish Kumar, the learned counsel for the respondent submits that the learned standing counsel for the Central Government having conceded that the rationale of the decision in Haji. A. Kareern Sait v. Dy. 6. Mr. Ambrish Kumar, the learned counsel for the respondent submits that the learned standing counsel for the Central Government having conceded that the rationale of the decision in Haji. A. Kareern Sait v. Dy. Commercial Tax Officer, Mettupalayam: 18 STC 370, which held that sub-rule (7) of R. 5 of the Central Sales Tax (Madras) Rules 1957, providing for limitation and determination of escaped turnover by best judgment was in excess of the rule-making power and the sub-rule as a whole, was therefore, invalid, would apply with equal force to R. 10-A as well and that in view of the same decision he would not be able to sustain the demands under R. 10-A and yet he could sustain the demand under R. 9(2) of the Rules, it is no longer open to the appellant to challenge the validity of R. 10-A in this appeal, and that too after so many years. 7. Counsel for the appellant answers that the learned standing counsel thereby cannot be said to have conceded that R. 10-A was invalid. He had only said that in view of the decision in 18 STC 370, he would not be able to sustain the demands under R. 10-A; and that even if it could be taken as a concession, the appellant could not be estopped from showing that the rule is valid so that Central Excise revenue is not allowed to escape. We agree with the learned counsel for the appellant and proceed to examine the validity of R. 10-A as it stood at the relevant time. Rule 10-A of the Rules read as under : "10-A. Residuary powers for recovery of sums due to Government - Where these Rules do not make any specific provision for the collection of any duty or any deficiency in duty if the duty has for any reason been short-levied, or of any other sum of any kind payable to the Central Government under the Act or these Rules, such duty, deficiency in duty or sum shall, on a written demand made by the proper officer, be paid to such person and at such time and place as the officer may specify." 8. Rule 10-A provided the machinery for collection of tax from the assessee after the goods had left the factory premises. Rule 10-A provided the machinery for collection of tax from the assessee after the goods had left the factory premises. This rule contemplated that the duty or deficiency in duty was payable on a written demand made by the proper officer in cases where either the Rules did not make any specific provision ,for the collection of any duty or of any deficiency in duty if the duty had for any reason been short-levied. Therefore, before R. 10-A could be resorted to, it had to be found that either the Central Excise Rules did not make any specific provision for the collection of duty in respect whereof a demand was being made by the proper officer, or that there was no specific provision therein for the collection of the deficiency in duty which had been short-levied for any reason. It was a residuary provision and it applied only when there was no other specific provision in the Rules. Where there had been no assessment at all there was no reason why claim and demand of the respondent (appellant?) could not be said to be recoverable under R. 10-A. 9. The learned counsel for the appellant submits that this Rule is perfectly valid being covered by the rule-making powers under the Act while the learned counsel for the respondent, submits that it is ultra vires the Act being not covered by its rule-making powers. The question, therefore, is whether the Rule is valid. 10. Chapter II of the Act deals with levy and collection of duty. Under S. 3 of the Act duties specified in First Schedule to the Act were to be levied. Sub-section (1) of S. 3, at the relevant time, read as follows : "(1) There shall be levied and collected in such manner as may be prescribed duties of excise on all excisable goods other than salt which are produced or manufactured in India, and a duty on salt manufactured in, or imported by land into any part of India as, and at the rates, set forth in the First Schedule." 11. In Citadel Fine Pharmaceuticals v. District Revenue Officer, Chingleput: (1973) 1 Mad LJ 99, where the enactment, namely, the Medicinal and Toilet Preparations (Excise Duties) Act (XVI of 1955) was silent on the question of levies of escaped assessment, it was held that the Rules made under that Act could not extend the charging power and R. 12, in so far as it sought to extend the charging power under S. 3 of that Act, was held to be invalid and without jurisdiction. Rule 12 of those Rules read as follows : "12. Residuary powers for recovery of sums due to Government - Where these rules do not make any specific provision for the collection of any duty or of any deficiency in duty if the duty has for any reason been short-levied, or of any other sum of any kind payable to the collecting Government under the Act or these rules, such duty, deficiency in duty or sum shall on written demand made by the proper officer, be paid to such person and at such time and place, as the proper officer may specify." 12. Rule 12 was somewhat similar to R. 10A of the Rules and had been held to be ultra vires on the ground that it did not have the required statutory backing. In M/s. Agarwal Brothers v. Union of India: (1972) 2 Mad LJ 476 it was held that a licence issued under the Central Excise Rules was personal to the licensee and therefore, a transferee of factory licensed to manufacture iron and steel products from the former licensee could only be treated as a new licensee after the relevant date mentioned in the Notification No. 131 of 1962, dated 13th June, 1962, and as the petitioner applied for a licence much later, the exemption under the Notification was not available to the petitioner who could not be applying for renewal of the earlier licence held by the transferors and hence the exemption under the Notification was not available to the petitioner. Demand, therefore, could only be made under R. 10-A which, it was held, could not be invoked in view of the decisions in W.P. No. 1053/68, namely the Citadel Fine (1973 1 Mad LJ 99) (supra). 13. Demand, therefore, could only be made under R. 10-A which, it was held, could not be invoked in view of the decisions in W.P. No. 1053/68, namely the Citadel Fine (1973 1 Mad LJ 99) (supra). 13. A Division Bench of Kerala High Court in Kerala Polythene v. Superintendent, Central Excise, since reported in 1977 Tax LR 1680, held that R. 10-A of the rules was not ultra vires the rule-making power conferred by the Act on the Central Government. Balakrishna Eradi, J. as he then was, observed that the scope of the rule-making power conferred by S. 3(l) of the Act was wide enough to embrace all matters relating to the manner in which both the levy and the collection of duties of excise on all excisable goods other than salt were to be made. The provision contained in R. 10-A was thus fully within the scope of the said power and hence it was not correct to say that R. 10-A was ultra vires the rule-making power conferred by the Act on the Central Government. The cases of Agarwal Brothers (1973 Tax LIZ 2213) (Mad) (supra) and Citadel Fine Pharmaceuticals (1973-1 Mad LJ 99) (supra) were distinguished pointing out that there was much difference in scopes of S. 3 of the Medicinal and Toilet Preparations (Excise Duties) Act (XVI of 1955) and of S. 3 of the Act. Comparing the provisions of the two Sections it was observed that there was fundamental difference in their policy and scheme. Under S. 3 of the Medicinal and Toilet Preparations Act only the manner of collection of the duties was left to be prescribed by the rules and levy of the duty was to be made at the rates specified in the Schedule to the Act. In enacting S. 3 of the Act i.e. Central Excises and Salt Act, the Parliament had empowered the rule-making authority to prescribe by rules the manner of levy of duties and also the manner of collection of duties of excise on ell excisable goods other than salt. Manifestly the rule making power conferred by this Section is very much wider in its ambit than the power conferred on the rule-making authority under S. 3 of the Medicinal and Toilet preparations (Excise Duties) Act where under only the manner of collection of duties could be laid down by rules. We respectfully agree with this view. Manifestly the rule making power conferred by this Section is very much wider in its ambit than the power conferred on the rule-making authority under S. 3 of the Medicinal and Toilet preparations (Excise Duties) Act where under only the manner of collection of duties could be laid down by rules. We respectfully agree with this view. We also find that in Agarwal Brothers (supra) though one-of the questions raised was the validity of R. 10-A of the Rules, the Court did not consider the said question on merits in view of the submission made by the standing counsel for the State Government on the basis of R. 10-A in the light of the earlier decisions of the same High Court, striking down R. 12 of the Medicinal and Toilet Preparations (Excise Duties) Rules. That decision can not obviously be regarded as authority supporting the contention that R. 10- A was ultra vires the rule-making power. 14. We find that R. 10-A, was incorporated because of the decision of the Nagpur High Court in Messrs Chhotabhai Jethabhai Patel v. Union of India ILR (1952) Nag 156. After that decision the Central Government by a notification, dated December 8, 1951, amended the Rules by addition of the new R. 10-A. The assessee challenged the validity of the Rule but a Full Bench of the Nagpur High Court rejected the assessees contention and held that R. 10-A covered a case for increased levy on the basis of a change of law. That decision was challenged before this Court unsuccessfully. This Court in Chhotabhai Jethabhai Patel and Co. v. Union of India: 1962 Suppl. (2) SCR 1 rejected the assessees claim regarding non-applicability of R. 10- A stating that it had been specifically designed for the enforcement of a demand like the one in that case. 15. We also find that in N. B. Sanjana v. Elphinstone Spinning and Weaving Mills Company Ltd. (1971) 1 SCC 337 : ( AIR 1971 SC 2039 ), while holding that R. 10-A did not apply to the facts of that case, this Court observed that R. 10-A did not apply as the specific provision for collection of duty in a case like that was specially provided for by R. 10 and, therefore, action should have been taken under that Rule. 16. In Assistant Collector v. National Tobacco Co. 16. In Assistant Collector v. National Tobacco Co. Ltd., (1973) 1 SCR 822 this Court held that the High Court erroneously refused to consider whether the impugned notice in that case fell under R. 10-A. It was observed that Rr. 10 and 10-A seemed to be so widely worded as to cover any inadvertence, error etc.; whereas R. 10-A would appear to cover any deficiency in duty if the duty had, for any reason, been short-levied, except that it would be outside the purview of R. 10-A if its collection was expressly provided by any Rule. It was further observed that both the Rules as they stood at the relevant time dealt with collection and not with assessment and what was said in N. B. Sanjanas case ( AIR 1971 SC 2039 ) (supra) that R. 10-A was of residual in character and would be inapplicable if a case fell within a specified category of cases mentioned in R. 10, was reiterated. 17. In D. R. Kohli v. Atul Products Ltd. (1985) 2 SCR 832 this Court pointed out the differences between the two Rules namely R. 10 and R. 10-A as: "(i) whereas R. 10 applies to cases of short levy through inadvertence, error, collusion or misconstruction on the part of an officer, or through mis-statement as to the quantity, the description or value of the excisable goods on the part of the owner, R. 10-A was a residuary clause applied to those cases which were not covered by R. 10 and that; (ii) whereas under R. 10, the deficit amount could not be collected after the expiry of three months from the date on which the duty or charge was paid or adjusted in owners account current or from the date of making the refund, R. 10-A did not contain any such period of limitation." 18. It would thus be clear that this Court interpreted R. 10-A, distinguished it from R. 10 and applied it to the appropriate facts and circumstances of different cases. It would be reasonable to infer that in none of the cases any doubt about the validity of the R. 10-A was entertained. 19. We may now examine the contention that at the relevant time R. 10-A was not covered by the rule making power conferred on the Central Government by S. 37. Section 37 dealt with power of Central Government to make Rules. 19. We may now examine the contention that at the relevant time R. 10-A was not covered by the rule making power conferred on the Central Government by S. 37. Section 37 dealt with power of Central Government to make Rules. Sub-section (1) said: "The Central Government may make rules to carry into effect the purposes of this Act." Subsection (2) enumerated the matters the rules might provide for in particular and "without prejudice to the generality of the foregoing power." Thus, the section did not require that the enumerated rules would be exhaustive. Any rule if it could be shown to have been made "to carry into effect the purposes of the Act" would be within the rule making power. Chapter II of the Act dealt with the levy and collection of duty. Section 3 as it stood at the relevant time provided that duties specified in the First Schedule were to be levied. We have quoted Sub-section (1). 20. The First Schedule contained Item Nos, description of goods and rates of duty. Section 3 has subsequently been amended by the Finance Acts of 1982 and 1984, and the Central Excise Tariff Act of 1985. This section, it would be seen, expressly empowered the levy and collection of duties of excise on all excisable goods as provided in the Act including its First Schedule. It could not, therefore, be said that R. 10-A was not covered by the above provision. 21. It is an accepted principle that delegated authority must be exercised strictly within the limits of the authority. If rule making power is conferred and the rules made are in excess of that power the rules would be void even if the Act provided that they shall have effect as though enacted in the Act as was ruled in State of Kerala v. K. M. Charial Abdullah & Co., (1965) 1 SCR 601 . Therein the High Court having declared R. 14-A of the Madras General Sales Tax Rules, 1939 as ultra vires, on appeal, this Court by majority held that the validity of the rule, even though it was directed to have effect as if enacted in the Act, was always open to challenge on the ground that it was unauthorised. Therein the High Court having declared R. 14-A of the Madras General Sales Tax Rules, 1939 as ultra vires, on appeal, this Court by majority held that the validity of the rule, even though it was directed to have effect as if enacted in the Act, was always open to challenge on the ground that it was unauthorised. The validity of the delegated legislation is generally a question of vires, that is, whether or not the enabling power has been exceeded or otherwise wrongfully exercised. Scrutinising the provisions of R. 10-A in the light of the above principles and pronouncements of this Court, we have no doubt that R. 10-A of the Rules, as it existed at the relevant time, was valid and not ultra vires the rule making power. Demand notices lawfully issued under the rule by the competent authority could not, therefore, be challenged on the ground of the R. 10-A itself being ultra vires. Whether those could be challenged on any other ground must necessarily depend on the facts and circumstances of the case. 22. The High Court having proceeded on the basis that R. 10-A was not available to support the demand notice, we set aside the impugned order of the High Court, allow the appeal, and remand the case to the High Court for disposal in accordance with law. We leave the other questions open. Under the peculiar facts and circumstance of the case, we leave the parties to bear their own costs. Appeal allowed. For Citation : AIR 1989 SC 1829
