Purchase tax recovery provisions operate only after a real taxable event; entry-point seizure cannot create liability.

Explanation 1 to section 2(1a-1) of the Bengal Finance (Sales Tax) Act, 1941 was treated as clear and workable; the absence of a prescribed disclosure form did not make the deeming definition of "casual trader" vague or ineffective. Section 4C(6) and (7) and rule 48L(4) were construed as anti-evasion and recovery provisions forming part of a complete scheme for purchase tax, but they could operate only where a taxable purchase had in fact occurred within West Bengal. Seizure and sale at the entry point could not create liability in the absence of the underlying taxable event.

Issues: (i) Whether Explanation 1 to section 2(1a-1) of the Bengal Finance (Sales Tax) Act, 1941 was vague or unworkable for want of a prescribed pro forma and machinery provision; (ii) Whether section 4C(6) and (7) of the Bengal Finance (Sales Tax) Act, 1941 and rule 48L(4) of the Bengal Sales Tax Rules, 1941 were unconstitutional and could operate to authorise seizure and sale of goods at the entry point in the absence of a taxable purchase within the State.

Issue (i): Whether Explanation 1 to section 2(1a-1) of the Bengal Finance (Sales Tax) Act, 1941 was vague or unworkable for want of a prescribed pro forma and machinery provision.

Analysis: The definition of 'casual trader' and the deeming provision in Explanation 1 were found to be clear and capable of application. The absence of a prescribed form for disclosure did not create vagueness or make the provision unworkable. A form would have been convenient, but its absence did not justify suspending the operation of the Explanation.

Conclusion: The challenge to Explanation 1 failed and the Tribunal's contrary finding was set aside.

Issue (ii): Whether section 4C(6) and (7) of the Bengal Finance (Sales Tax) Act, 1941 and rule 48L(4) of the Bengal Sales Tax Rules, 1941 were unconstitutional and could operate to authorise seizure and sale of goods at the entry point in the absence of a taxable purchase within the State.

Analysis: Section 4C was read as a complete scheme for levy and recovery of purchase tax from a casual trader, and sub-sections (6) and (7) together with rule 48L(4) were treated as anti-evasion and recovery provisions. The power of seizure and sale was held to arise only where tax was otherwise lawfully payable on a taxable purchase within West Bengal. In the absence of the taxable event, no transporter could be made liable at the entry point merely for failure to disclose particulars.

Conclusion: The provisions were upheld as valid, but they could not be applied to fasten liability without an underlying taxable purchase; the Tribunal's invalidation of these provisions was set aside.

Final Conclusion: The statutory provisions were construed in a manner that preserved their validity and confined them to recovery of tax arising from an actual taxable purchase, and the appeal succeeded.

Ratio Decidendi: Recovery and seizure provisions meant to prevent tax evasion can operate only where the statute is otherwise attracted by a real taxable event; they cannot create liability in the absence of such event.
