Retrospective excise duty remains valid where it taxes manufacture itself and Rule 10A supports recovery of differential duty.

Retrospective enhancement of excise duty was treated as a valid duty of excise because the levy remained one on goods manufactured or produced in India, and its retrospective operation did not alter its constitutional character. The Court further held that retrospectivity in a taxing statute, by itself, did not violate Articles 19(1)(f), 19(5), 31(1), 31(2) or 265, since taxation is a sovereign function and the inability to pass on the burden in a particular case does not make the levy unreasonable. Rule 10A of the Central Excise Rules, 1944 was construed as a residuary recovery provision wide enough to support collection of the differential duty arising from the enhanced rate.

Issues: (i) Whether the retrospective enhancement of excise duty under section 7(2) of the Indian Finance Act, 1951 was beyond Parliament's legislative competence under Entry 84 of List I; (ii) whether the retrospective levy violated the fundamental rights guaranteed by Articles 19(1)(f), 19(5), 31(1), 31(2) and 265 of the Constitution of India; and (iii) whether Rule 10A of the Central Excise Rules, 1944 authorised recovery of the differential duty.

Issue (i): Whether the retrospective enhancement of excise duty under section 7(2) of the Indian Finance Act, 1951 was beyond Parliament's legislative competence under Entry 84 of List I.

Analysis: A duty of excise was held to be a tax on goods manufactured or produced in India, attracted by manufacture itself and not by any sale or other commercial transaction. The Court rejected the contention that retrospectivity destroyed the character of the levy merely because the burden could not in every case be passed on. The meaning of Entry 84 was found to depend on the nature of the levy, not on the economic incidence of collection or on the ability of a particular taxpayer to shift the burden. The levy continued to answer the description of a duty of excise notwithstanding its retrospective operation.

Conclusion: The retrospective levy was within Parliament's legislative competence and was valid.

Issue (ii): Whether the retrospective levy violated the fundamental rights guaranteed by Articles 19(1)(f), 19(5), 31(1), 31(2) and 265 of the Constitution of India.

Analysis: A taxing law was held not to be rendered unconstitutional merely because it operated retrospectively. Article 265 required authority of law, but did not place tax laws outside the operation of constitutional limitations; however, mere retrospectivity did not by itself amount to an unreasonable restriction on the right to hold property. The Court also held that Article 31 was not attracted to the imposition or collection of tax in the manner contended. The challenge under Article 19(1)(f) failed because taxation is a sovereign function in the public interest and the inability to pass on the burden in a particular case did not transform the levy into an unreasonable restriction.

Conclusion: The levy did not infringe Articles 19(1)(f), 19(5), 31(1), 31(2) or 265.

Issue (iii): Whether Rule 10A of the Central Excise Rules, 1944 authorised recovery of the differential duty.

Analysis: Rule 10A was construed as a residuary provision wide enough to cover any deficiency in duty short-levied for any reason where the rules made no specific provision. The differential duty arising from the retrospective enhancement of excise rates was held to fall within that language, and the recovery demand was therefore supported by the rules.

Conclusion: Rule 10A validly authorised recovery of the differential duty.

Final Conclusion: The retrospective excise levy and the machinery for its recovery were upheld, and the challenge to the demand failed in its entirety.

Ratio Decidendi: A levy remains a duty of excise if it is imposed on goods manufactured or produced in India, even when made retrospectively, and neither retrospective operation nor inability in a particular case to pass on the burden invalidates it under the Constitution.
