Retrospective tax reassessment remains valid, but reopening ends when the statutory books-retention period expires to preserve taxpayer fairness.
Retrospective insertion of Section 42(3) of the Kerala Value Added Tax Act validly created a distinct assessment-reopening regime for dealers above the prescribed turnover threshold. Higher turnover constituted an intelligible differentia rationally connected to taxing escaped turnover, so the classification did not violate Article 14. However, reopening power cannot extend beyond the period for which dealers must retain books under Rule 58(20) of the Kerala Value Added Tax Rules. Retrospectivity must not unfairly deprive dealers of the practical ability to defend escaped-turnover allegations. The amendment was therefore sustained, subject to this records-retention limitation; notices and orders require assessment on that basis.
Issues: (i) Whether the retrospective insertion of Section 42(3) of the Kerala Value Added Tax Act, 2003, creating a special regime for reopening assessments of dealers with turnover above the prescribed threshold, is constitutionally valid and consistent with Article 14. (ii) Whether the power to reopen assessments under Section 42(3) can be exercised after the period during which the dealer is obliged to retain books of account under Rule 58(20) of the Kerala Value Added Tax Rules has expired.
Issue (i): Whether the retrospective insertion of Section 42(3) of the Kerala Value Added Tax Act, 2003, creating a special regime for reopening assessments of dealers with turnover above the prescribed threshold, is constitutionally valid and consistent with Article 14.
Analysis: The retrospective amendment was held to be within legislative competence. The classification of dealers having turnover above the threshold under Section 42(1) for a distinct reopening procedure was treated as based on an intelligible differentia, namely higher turnover, and as having a rational nexus with the object of bringing escaped turnover to tax. The provision was therefore not regarded as hostile discrimination or as treating unequals as equals.
Conclusion: The retrospective operation of Section 42(3) was upheld and the challenge based on Article 14 failed.
Issue (ii): Whether the power to reopen assessments under Section 42(3) can be exercised after the period during which the dealer is obliged to retain books of account under Rule 58(20) of the Kerala Value Added Tax Rules has expired.
Analysis: Although Section 42(3) was given retrospective effect, the Court held that retrospectivity could not be carried to a point that causes unfair prejudice or deprives the dealer of the practical ability to defend against allegations of escaped turnover. The retention period of books under Rule 58(20) was treated as a safe guide for controlling the reach of the reopening power, so as to preserve certainty and fairness in taxation.
Conclusion: Reopening under Section 42(3) cannot be exercised once the books-retention period under Rule 58(20) has expired.
Final Conclusion: The amendment was sustained, but its operation was confined by the books-retention period, and the impugned notices and orders were left to be tested on that basis.
Ratio Decidendi: A retrospective fiscal amendment may validly create a special reopening regime, but its operation can be judicially confined to the period within which the assessee is required to retain records, where unlimited retrospectivity would undermine fairness, certainty, and the ability to defend the assessment.
