Customs duty variation upheld where public-interest exemption power allowed rate adjustment under the statutory scheme.

Consumers of viscose staple fibre had sufficient locus standi to challenge customs notifications because the duty burden affected them directly in the market, and the petitions were maintainable to the extent relief could be granted within the Court's territorial reach. The notifications fixing additional duty at a rate different from the excise duty on indigenous fibre were upheld as valid: section 3(1) of the Customs Tariff Act creates the levy, while section 3(6) carries in the exemption machinery of section 25 of the Customs Act, permitting variation or exemption in public interest. The challenge under Articles 14, 19(1)(g) and 265 failed because the fiscal scheme allowed such statutory adjustment and the notifications were traceable to lawful authority.

Issues: (i) Whether the petitioners had locus standi to challenge the impugned notifications and seek the reliefs claimed. (ii) Whether the High Court had territorial jurisdiction to entertain the challenge in respect of the reliefs sought. (iii) Whether the notifications fixing the additional duty at a rate different from the excise duty on indigenous viscose staple fibre were ultra vires or violative of Articles 14, 19(1)(g) and 265, having regard to the power under section 3(6) of the Customs Tariff Act, 1975 read with section 25 of the Customs Act, 1962.

Issue (i): Whether the petitioners had locus standi to challenge the impugned notifications and seek the reliefs claimed.

Analysis: The petitioners were consumers of viscose staple fibre and were directly affected in the market by the comparative burden of duty on imported and indigenous fibre. The challenge was not that of strangers to the subject matter, and the passing-on of excise burden to purchasers gave them a sufficient legal interest in the controversy.

Conclusion: The issue was decided in favour of the petitioners; they had sufficient locus standi.

Issue (ii): Whether the High Court had territorial jurisdiction to entertain the challenge in respect of the reliefs sought.

Analysis: Although relief relating to the excise levy at the place of manufacture could not be granted in relation to an out-of-State factory, the petition also sought a direction affecting the customs side of the levy and the competitive position of the petitioners within the Court's territorial reach. To that extent, the proceeding was maintainable.

Conclusion: The issue was decided in favour of the petitioners to the extent of maintainability for the relief capable of being granted by the Court.

Issue (iii): Whether the notifications fixing the additional duty at a rate different from the excise duty on indigenous viscose staple fibre were ultra vires or violative of Articles 14, 19(1)(g) and 265, having regard to the power under section 3(6) of the Customs Tariff Act, 1975 read with section 25 of the Customs Act, 1962.

Analysis: Section 3(1) of the Customs Tariff Act, 1975 creates the levy of additional duty equal to the excise duty on a like article, but section 3(6) makes the exemption machinery under the Customs Act applicable, including the public-interest exemption under section 25(1). The levy was part of a fiscal scheme in which the Government could adjust rates to meet changing economic conditions, and the Court declined to treat section 3(1) as excluding that power. The challenge based on Articles 14 and 19(1)(g) failed because taxation policy allows wide latitude in classification and regulation, and Article 265 was not infringed once the notifications were traceable to statutory authority.

Conclusion: The issue was decided against the petitioners; the notifications were held valid and within the Government's power.

Final Conclusion: The challenge to the impugned notifications failed, and the petitions stood dismissed on the footing that the Government possessed authority to vary or exempt the additional duty in public interest under the statutory scheme.

Ratio Decidendi: The additional duty under section 3(1) of the Customs Tariff Act, 1975 is subject to the exemption power carried into that Act by section 3(6), so that the Central Government may, in public interest and through the mechanism of section 25 of the Customs Act, 1962, vary or exempt the levy instead of being rigidly bound to match the excise rate in all circumstances.
