Retrospective tax validation upheld where the legislature itself defined the levy and no repugnancy with existing laws was shown.

A retrospective validating tax law was upheld because the legislature itself identified the levy, its subject matter, and the basis for assessment and collection, leaving no essential legislative function to be delegated; the challenge based on excessive delegation therefore failed. The Pondicherry Legislature, having powers co-extensive with a State Legislature under Article 239A and the Government of Union Territories Act, 1963, could enact retrospective validating legislation on petrol and diesel within its competence, so the competence challenge failed. The enactment was also not repugnant to the continuing and parliamentary laws governing Pondicherry, as those provisions did not bar a fresh levy by a competent legislature and no inconsistent parliamentary levy existed.

Issues: (i) Whether the Validation Act suffered from excessive delegation of legislative power; (ii) whether the Pondicherry Legislature had competence to enact a retrospective validating law imposing the levy; (iii) whether the Validation Act was repugnant to the continuing and parliamentary enactments governing Pondicherry.

Issue (i): Whether the Validation Act suffered from excessive delegation of legislative power.

Analysis: The levy had already been fixed under the municipal regime, and the validating enactment itself identified the tax, the subject-matter, and the legal basis for assessment and collection. No further subordinate legislation or delegated choice was required to give effect to the levy. The legislative measure was a direct validation of an existing levy and not a case where essential legislative functions were surrendered to another authority.

Conclusion: The challenge based on excessive delegation failed.

Issue (ii): Whether the Pondicherry Legislature had competence to enact a retrospective validating law imposing the levy.

Analysis: Under Article 239A of the Constitution of India and Section 18 of the Government of Union Territories Act, 1963, the Pondicherry Legislature had powers co-extensive with those of a State Legislature in respect of matters in the State and Concurrent Lists, subject to Parliament's overriding power. A legislature with such powers may enact retrospective validating legislation. The levy on petrol and diesel was within legislative competence, and the validating enactment operated as a legislative re-enactment of the tax.

Conclusion: The Pondicherry Legislature had the power to enact the retrospective validating law.

Issue (iii): Whether the Validation Act was repugnant to the continuing and parliamentary enactments governing Pondicherry.

Analysis: Section 7 of the Pondicherry (Administration) Act, 1962 continued existing levies but did not prohibit a competent legislature from imposing a fresh levy. Section 21 of the Government of Union Territories Act, 1963 did not bar the impugned enactment, since Parliament had not itself enacted any inconsistent levy on petrol and diesel. The validating law therefore did not conflict with the Parliamentary enactments relied upon.

Conclusion: The plea of repugnancy failed.

Final Conclusion: The validating levy was upheld, and the appellants' challenge to the tax failed in all respects.

Ratio Decidendi: A competent legislature with powers equivalent to a State Legislature may retrospectively validate and re-enact a tax levy already identifiable in substance, and such a law is not invalid for excessive delegation or repugnancy merely because it overrides earlier continuing provisions.
