Strict-liability tax penalty under a simplified reassessment scheme was upheld as non-arbitrary and non-discriminatory.

Section 17(5A) of the Kerala General Sales Tax Act is described as a penalty provision linked to the special reassessment procedure under section 17(4), designed to deter abuse of the simplified assessment facility. Dealers using that mechanism are treated as a distinct class, and the differential penalty is supported by the objective of protecting revenue and preventing tax evasion. The provision is characterised as a strict-liability penalty, so the absence of discretion in the prescribed penalty does not render it arbitrary. Mens rea is not treated as a necessary ingredient unless the statute expressly requires it, and the expropriatory challenge was not examined for lack of factual basis.

Issues: Whether section 17(5A) of the Kerala General Sales Tax Act, 1963, imposing penalty equal to thrice the tax difference on reassessment under section 17(4), is unconstitutional as arbitrary, discriminatory or expropriatory, and whether proof of mens rea or discretion in quantum of penalty is .

Analysis: Section 17(4) confers a simplified assessment facility on a specified class of dealers on the basis of returns accepted with limited scrutiny. Section 17(5A) is linked to that special procedure and operates as a deterrent against abuse of the dealer-friendly mechanism. Dealers who opt for the simplified method form a distinct class from those assessed under the regular procedure, and the differential treatment in penalty is supported by the object of protecting revenue and preventing tax evasion. The provision was held to create a strict-liability penalty, so the absence of discretion in imposing the prescribed penalty does not make it arbitrary. Relying on the principle that tax delinquency penalties are remedial and coercive, the Court held that mens rea is not a necessary ingredient unless the statute expressly requires it. The expropriatory challenge was not examined on merits for want of factual basis.

Conclusion: Section 17(5A) is valid and constitutional; it is neither arbitrary nor discriminatory, and penalty can be imposed without proving mens rea.

Final Conclusion: The writ appeal was dismissed and the judgment upholding the impugned provision was affirmed.

Ratio Decidendi: A penalty attached to a special self-assessment procedure may validly operate as strict liability for abuse of that concession, and mens rea need not be proved unless the statute so requires.
