Transporter taxation limits: deemed-sale and advance-tax machinery struck down, while purchase-tax machinery and disclosure duty were largely upheld.

A transporter may be treated as a casual trader only to the limited extent of being required to disclose consignor or consignee particulars, and that obligation was held valid but not enforceable until the prescribed mode of disclosure is available. The deemed-sale explanation under section 11(1) and the connected advance-tax, security, detention, seizure and penalty machinery were struck down as unconstitutional in their application to transporters because they used a legal fiction to impose tax on transport activity rather than on an actual taxable sale. By contrast, the purchase-tax machinery under section 14 and rule 189 was upheld, as liability depends on proof of an actual purchase. Service of assessment or demand notices on drivers or persons in charge of goods vehicles was held invalid where the transporter was not otherwise liable.

Issues: (i) Whether the inclusion of a transporter within the definition of casual trader under section 2(6) of the West Bengal Sales Tax Act, 1994 was valid, subject to the requirement of disclosure of consignor or consignee particulars; (ii) Whether the Explanation below section 11(1), and the connected advance-tax, security, detention, seizure and penalty provisions in section 11 and rules 172, 173, 174 and the related forms, were constitutional as applied to transporters; (iii) Whether the corresponding purchase-tax machinery under section 14 and rule 189 was valid as applied to transporters; (iv) Whether notices of assessment and demand could validly be served on drivers or persons in charge of goods vehicles.

Issue (i): Whether the inclusion of a transporter within the definition of casual trader under section 2(6) of the West Bengal Sales Tax Act, 1994 was valid, subject to the requirement of disclosure of consignor or consignee particulars.

Analysis: The definition of casual trader, so far as it applied to a transporter, imposed only alternative obligations: to disclose the name and address of the consignor or consignee in West Bengal, or to furnish one of the specified transport documents. Those obligations were held to be capable of performance in the ordinary course of transport business and, therefore, within legislative competence. The legal fiction deeming the transporter to have brought, procured or purchased the goods on his own account was read narrowly as a fiction confined to the definition, and not as authorising tax on a mere movement of goods. At the same time, the requirement of disclosure of names and addresses could not be enforced until the manner of such disclosure was prescribed.

Conclusion: Section 2(6) was upheld as valid and constitutional, but the disclosure requirement was kept in suspense until the prescribed manner was made available.

Issue (ii): Whether the Explanation below section 11(1), and the connected advance-tax, security, detention, seizure and penalty provisions in section 11 and rules 172, 173, 174 and the related forms, were constitutional as applied to transporters.

Analysis: The Explanation below section 11(1) created an adverse presumption that a transporter's disposal of goods amounted to a sale, even without any antecedent failure to discharge a statutory obligation. That presumption was held to be unreasonable, arbitrary and beyond the State's competence under entry 54 read with article 366(29A), because a transporter, in the ordinary course of business, is not reasonably and proximately connected with sale and cannot be burdened to prove a negative in the manner required by the provision. The advance-tax and security mechanism in sub-sections (7) and (8), together with the detention-linked power in sub-section (5)(ii) and the consequential provisions in sub-sections (10) to (12), were treated as a circuitous method of levying tax before an actual taxable sale and were struck down as unconstitutional. Rules 172, 173 and 174, and forms 28 and 31 to the extent they implemented that advance-tax or security scheme, fell with the parent provisions. The machinery rules for ordinary assessment under section 11 were not disturbed.

Conclusion: The Explanation below section 11(1), sections 11(7), 11(8), the words linked to sub-sections (7) and (8) in section 11(5)(ii), sections 11(10), 11(11) and 11(12) in their application to transporters, rules 172, 173 and 174, and forms 28 and 31 to that extent, were struck down.

Issue (iii): Whether the corresponding purchase-tax machinery under section 14 and rule 189 was valid as applied to transporters.

Analysis: Section 14 was treated as a charging and machinery provision for purchase tax on a casual trader's actual purchases in West Bengal. The Court held that the levy could not rest merely on the deeming fiction in section 2(6), but only on proof of an actual purchase within the statutory and constitutional concept of sale or purchase. For that reason the purchase-tax machinery itself was not invalid merely because it operated in relation to a transporter. Rule 189, being the machinery provision for determining purchase tax, was upheld, and form 32 was held valid as a general form relating to section 14.

Conclusion: Section 14 and rule 189 were upheld as valid for transporters, and form 32 was sustained.

Issue (iv): Whether notices of assessment and demand could validly be served on drivers or persons in charge of goods vehicles.

Analysis: A driver or person in charge of a goods vehicle fell within the statutory definition of transporter, but the Act did not authorise service of notices on such persons where the transporter itself was not liable as a casual trader or otherwise. The Court held that, in the absence of any agency relationship under the Carriers Act, the respondents could not treat the driver as a proper recipient of notices of proceeding or demand notices intended for the transporter.

Conclusion: Service of assessment or demand notices on drivers or persons in charge of goods vehicles was held invalid where the transporter was not liable.

Final Conclusion: The challenge succeeded only in part. The definition of casual trader was sustained with a limited suspension of the disclosure obligation, but the deeming sale/purchase based tax provisions, the advance-tax and security scheme, and the associated invalid forms and related enforcement provisions were set aside so far as they applied to transporters, while the ordinary purchase-tax machinery under section 14 and the corresponding rule survived.

Ratio Decidendi: A transporter may be subjected only to obligations that are reasonably capable of performance and are closely connected with an actual taxable sale or purchase; a legislative fiction cannot be used to impose tax on a mere transport activity or to create an advance-tax or deemed-sale liability beyond the scope of entry 54 read with article 366(29A) of the Constitution of India.
