Retrospective compounding tax amendment under Kerala sales tax law treated as workable and constitutionally valid

The Kerala General Sales Tax Act's amended compounding provision is discussed as applying retrospectively from 01.07.2006, so the revised computation method governs dealers who had opted for compounded tax for 2006-07. The text explains that compounding remains optional, but once chosen, liability is worked out under the amended scheme using the prescribed comparison with the highest turnover tax reflected in returns, accounts or prior years. It also states that Section 7(a) and Section 7(b) are not separate taxation spheres: the higher figure under the statutory comparison controls the compounded liability. The provision is described as workable on its own terms and not violative of Articles 14 or 19(1)(g).

Issues: (i) Whether amended Section 7(b) of the Kerala General Sales Tax Act, 1963, applied retrospectively to dealers who had opted for compounded tax for the assessment year 2006-07 under the unamended provision; (ii) Whether Section 7(a) and Section 7(b) operated in different spheres and whether the amended provision was unconstitutional as violative of Articles 14 and 19(1)(g) of the Constitution of India.

Issue (i): Whether amended Section 7(b) of the Kerala General Sales Tax Act, 1963, applied retrospectively to dealers who had opted for compounded tax for the assessment year 2006-07 under the unamended provision.

Analysis: The amendment to Section 7 introduced a revised method for computing compounded tax and was brought into force retrospectively from 01.07.2006. The compounding facility remained optional, but once opted, the liability had to be worked out under the amended scheme for the relevant year. The provision supplied the necessary working mechanism by directing computation with reference to the highest turnover tax shown in the return, accounts, or paid for the previous three consecutive years. The absence of a separate challengeable defect in machinery was negatived.

Conclusion: The amended Section 7(b) applied to dealers who had opted for compounded tax for 2006-07, even though the option had been exercised under the unamended provision.

Issue (ii): Whether Section 7(a) and Section 7(b) operated in different spheres and whether the amended provision was unconstitutional as violative of Articles 14 and 19(1)(g) of the Constitution of India.

Analysis: Section 7(b) did not create a separate and independent field of taxation. The phrase "whichever is higher" was held to require comparison between the figures worked out under Section 7(a) and Section 7(b), so that the higher of the two would govern the compounded liability. The provision was found to be workable on its own terms, without any impermissible supplementation by the executive. No hostile discrimination or unreasonable restriction was made out merely because the compounding rate was revised mid-year with retrospective effect.

Conclusion: Section 7(a) and Section 7(b) did not operate in different spheres, and the amended provision was not violative of Articles 14 or 19(1)(g).

Final Conclusion: The retrospective amendment to the compounding provision was held valid and enforceable for the assessment year 2006-07, and the assessees were not entitled to resist its application; the appeals and writ petitions were dismissed.

Ratio Decidendi: Where a taxing provision expressly supplies the method of computation, a retrospective amendment altering compounded liability for part of the assessment year is valid and can be applied to opted assessees, and the provision must be read as a workable whole without treating related clauses as operating in separate spheres.
