Case Note & Summary
The Supreme Court dismissed four civil appeals filed by dealers in mineral oils, including furnace oil, challenging the constitutional validity of the Madras General Sales Tax (Third Amendment) Act, 1967. The dispute arose from the taxation of furnace oil, a non-lubricating mineral oil, under the Madras General Sales Tax Act, 1959. Originally, Entry 47 of the First Schedule taxed only lubricating oils and greases at 6 per cent on first sale. With effect from April 1, 1964, Madras Act 7 of 1964 amended Entry 47 to include 'all kinds of mineral oils (not otherwise provided for in this Act), quenching oils and greases.' Until September 30, 1965, assessments proceeded on the basis that furnace oil remained subject to multipoint tax at 2 per cent, and dealers collected tax accordingly. The Board of Revenue, by a resolution dated August 28, 1965, declared that amended Entry 47 included furnace oil and transformer oil; dealers then began charging 6 per cent on first sale of furnace oil from September 14, 1965. The Madras High Court, in Burmah Shell Oil Storage and Distributing Company of India Limited v. State of Madras, (1968) 21 S.T.C. 227, held on August 2, 1967 that amended Entry 47 did not include furnace oil because the words 'all kinds of mineral oils' had a limited meaning limited to lubricants. This decision led to the enactment of the Madras General Sales Tax (Third Amendment) Act, 1967, which received the Governor's assent on December 29, 1967 and was published on January 5, 1968. The amending Act recast Entry 47 and inserted new Entry 47-A, retrospectively imposing tax on all kinds of mineral oils, including furnace oil, from April 1, 1964 at varying rates: 6 per cent until November 30, 1965; 6.5 per cent from December 1, 1965 to June 17, 1967; and 7 per cent from June 18, 1967. Section 4 validated all taxes levied or collected on such goods before the publication of the amending Act and barred refund suits. The appellants filed writ petitions under Article 226 challenging these provisions as violating Articles 14 and 19 of the Constitution, arguing that the retrospective imposition of a single point tax on furnace oil for the period prior to January 5, 1968 was unreasonable and illegal. The High Court dismissed the writ petitions, and the Supreme Court granted certificate for appeal. Before the Supreme Court, the appellants contended that Sections 2 and 4 of the amending Act imposed an unreasonable restriction on their right to carry on trade under Article 19(1)(g). The respondent State argued that the legislature had power to enact retrospective laws and that the validating Act cured the infirmity identified by the High Court. The Supreme Court held that legislative power includes both prospective and retrospective operation and the auxiliary power to validate laws found invalid. The court observed that the Government requires revenue to administer and fulfil its obligations, and that amending and validating Acts to make 'small repairs' are permissible in fiscal legislation. The retrospective imposition was found not to be an unreasonable restriction. The appeals were dismissed, and the provisions of the Madras General Sales Tax (Third Amendment) Act, 1967 were held valid.
Headnote
A) Constitutional Law - Legislative Competence - Retrospective Legislation and Validating Acts - Constitution of India, Article 19(1)(g); Madras General Sales Tax Act, 1959; Madras General Sales Tax (Third Amendment) Act, 1967 - The legislative power conferred on appropriate legislatures to enact laws in respect of topics covered by entries in the three lists can be exercised both prospectively and retrospectively, and includes the auxiliary power to validate laws found invalid. The amending Act was intended to cure an infirmity revealed by the Madras High Court judgment in Burmah Shell and to validate the past levy and collection of tax on non-lubricating mineral oils including furnace oil from April 1, 1964. Held that the impugned provisions were a valid piece of legislation and did not contravene Article 19. (Not mentioned) B) Constitutional Law - Fundamental Rights - Reasonableness of Restriction on Trade - Constitution of India, Article 19(1)(g); Madras General Sales Tax (Third Amendment) Act, 1967, Sections 2 and 4 - Retrospective imposition of single point sales tax on furnace oil and other non-lubricating mineral oils for the period prior to January 5, 1968 did not constitute an unreasonable restriction on the right to carry on trade or business. The Government needs revenue to carry on administration and fulfil its obligations to citizens; an amending and validating Act to make small repairs is permissible and frequently resorted to in fiscal enactments. Held that the retrospective operation was not unreasonable. (Not mentioned) C) Taxation - Sales Tax - Interpretation of Entry 47 - Madras General Sales Tax Act, 1959, First Schedule Entry 47 as amended by Madras Act 7 of 1964 - Furnace oil, being a non-lubricating mineral oil, was held by the Madras High Court in Burmah Shell Oil Storage and Distributing Company of India Limited v. State of Madras, (1968) 21 S.T.C. 227 not to be included in amended Entry 47, leading to the enactment of the Third Amendment Act. The amending Act split the original entry into entries 47 and 47-A, retrospectively including all kinds of mineral oils including furnace oil at specified rates. Held that this legislative clarification and validation was valid. (Not mentioned) D) Constitutional Law - Equality - Article 14 Challenge to Retrospective Tax - Constitution of India, Article 14; Madras General Sales Tax (Third Amendment) Act, 1967 - Appellants contended that retrospective imposition of tax violated Article 14, but the High Court repelled this contention; no unreasonable classification or discrimination was established. The Supreme Court while dismissing the appeals did not find merit in the Article 14 challenge. Held that the retrospective levy did not violate Article 14. (Not mentioned)
Issue of Consideration
Whether the provisions of the Madras General Sales Tax (Third Amendment) Act, 1967 (Act No. 19 of 1967) were invalid on the ground that they imposed sales tax with retrospective effect in an unreasonable manner and violated Articles 14 and 19 of the Constitution.
Final Decision
The Supreme Court dismissed the appeals and upheld the constitutional validity of the Madras General Sales Tax (Third Amendment) Act, 1967. The retrospective imposition of sales tax on all kinds of mineral oils including furnace oil from April 1, 1964, and the validation under Section 4 were held valid and not violative of Articles 14 and 19(1)(g).
Law Points
- Legislative power can be exercised both prospectively and retrospectively
- Legislature has auxiliary power to validate laws found invalid
- Validating Act to cure infirmity and impose retrospective tax is permissible
- Retrospective tax must not constitute unreasonable restriction on trade under Article 19(1)(g)
- Government needs revenue and small repairs in fiscal enactments are allowed
