Pith and substance doctrine sustains electricity surcharge levy and retrospective validation where legislative competence cures the prior defect.

The Kerala electricity surcharge was upheld as a tax in pith and substance on the consumption or sale of electricity, since the true character of a levy depends on substance rather than nomenclature. The Court held that supply to industrial consumers involves simultaneous consumption and sale, bringing the impost within Entry 53 of List II and the State's legislative competence under Article 246(3). The validating provision preserving past collections was also sustained because the legislature had competence and retrospectively removed the defect identified in the earlier invalidation. Retrospective validation was held permissible where it cures the basis of the prior judgment without usurping judicial power.

Issues: (i) Whether the Kerala Electricity Surcharge enactment was, in pith and substance, a tax on the consumption or sale of electricity falling within Entry 53 of List II and therefore within the legislative competence of the State; (ii) whether the validating provision preserving past surcharge collections was unconstitutional as an encroachment on judicial power.

Issue (i): Whether the Kerala Electricity Surcharge enactment was, in pith and substance, a tax on the consumption or sale of electricity falling within Entry 53 of List II and therefore within the legislative competence of the State.

Analysis: The charging provision described the impost as a surcharge on supply of electricity, but the Court held that nomenclature is not conclusive and the true character of the law must be gathered from its substance. Applying the doctrine of pith and substance and a liberal construction of taxing entries, the Court held that supply of electricity to industrial consumers results in simultaneous consumption and sale, and that the surcharge is a compulsory exaction forming part of the public revenue. The levy therefore answered the description of a tax on consumption or sale of electricity and fell within the State's legislative field under Entry 53 of List II read with Article 246(3) of the Constitution of India.

Conclusion: The enactment was within the legislative competence of the State and was valid as a tax measure under Entry 53 of List II.

Issue (ii): Whether the validating provision preserving past surcharge collections was unconstitutional as an encroachment on judicial power.

Analysis: The Court reiterated that a legislature cannot simply overrule a judicial decision or command the Court to ignore its judgment. However, validating legislation is permissible if the legislature has competence over the subject and cures the defect identified by the earlier judgment with retrospective effect. Section 11 removed the very basis on which the earlier levy had been struck down, treated the past collections as valid under the new law, and did not purport to exercise judicial power. The provision therefore fell within the accepted limits of retrospective validation and did not violate the constitutional separation of powers.

Conclusion: The validating provision was constitutionally valid and did not amount to an impermissible encroachment on judicial power.

Final Conclusion: The challenge to the surcharge enactment failed in full, and the levy together with its retrospective validation was upheld.

Ratio Decidendi: A taxing statute is to be tested by its substance, not its label, and a validating law is constitutional if the legislature has competence and retrospectively removes the defect that formed the basis of the prior judicial invalidation.
