Commercial parlance governs commodity classification; seizure needs bona fide suspicion of tax evasion and statutory necessity.

Seizure of books and documents under section 14(3) of the Bengal Finance (Sales Tax) Act, 1941 required a bona fide basis to suspect tax evasion and a necessity for seizure; absent credible material showing evasion under that Act, the drastic measure was not justified and the documents were to be released. For classification, a mosquito mat containing Allethrin was treated as an insecticide because the term was not defined in the taxing law and had to be understood in commercial parlance; the notification did not need to refer expressly to the Insecticides Act, 1968 for that trade meaning to apply. The commodity was therefore treated as a notified item under the West Bengal Sales Tax Act, 1954.

Issues: (i) Whether the seizure of books and documents was valid under section 14(3) of the Bengal Finance (Sales Tax) Act, 1941. (ii) Whether the mosquito mat manufactured by the applicant was an insecticide and therefore a notified commodity under Notification No. 1259-F.T. dated March 29, 1986, issued under section 25 of the West Bengal Sales Tax Act, 1954.

Issue (i): Whether the seizure of books and documents was valid under section 14(3) of the Bengal Finance (Sales Tax) Act, 1941.

Analysis: Seizure under section 14(3) could be justified only if there was a bona fide reason to suspect evasion or attempted evasion of tax under the Act of 1941 and if seizure was necessary for detection or prevention of such evasion. The materials showed that the applicant was registered and had been dealing with the mats under the West Bengal Sales Tax Act, 1954, and there was no credible basis to infer evasion under the Act of 1941. The officer could have proceeded by other lawful means, including action concerning registration or assessment, but the drastic step of seizure was not supported by the statutory preconditions.

Conclusion: The seizure was invalid and the seized documents were liable to be released to the applicant.

Issue (ii): Whether the mosquito mat manufactured by the applicant was an insecticide and therefore a notified commodity under Notification No. 1259-F.T. dated March 29, 1986, issued under section 25 of the West Bengal Sales Tax Act, 1954.

Analysis: The expression "insecticide" was not defined in the taxing enactments or the notification, so its meaning had to be gathered from commercial parlance and trade understanding. In that market context, the mat containing Allethrin and sold as a mosquito mat insecticide was treated as an insecticide, and the regulatory scheme under the Insecticides Act, 1968 reinforced that commercial understanding. The absence of an express reference to the Insecticides Act, 1968, in the notification did not displace the trade meaning of the commodity for sales tax purposes.

Conclusion: The mat was held to be an insecticide and a notified commodity under the West Bengal Sales Tax Act, 1954.

Final Conclusion: The application succeeded on both the legality of seizure and the tax classification of the commodity, and the applicant was entitled to the consequential reliefs granted in the order.

Ratio Decidendi: Where a taxing entry or notification does not define a commodity, its classification is determined by trade or commercial parlance, and coercive seizure under a tax statute cannot stand unless the statutory preconditions for reasoned suspicion of tax evasion are satisfied.
