Binding tax circulars and strict construction of tariff entries can determine classification of latex and rubber commodities.

A tax circular clarifying that field latex and centrifuged latex are the same commodity binds revenue officers so long as it remains in force and has not been withdrawn. The Board's power to issue instructions for proper administration was treated as wide enough to issue this clarification, and the circular was not ultra vires because it did not create an exemption contrary to the Act. The relevant entry for rubber was read strictly on its plain language, with the listed latex forms treated as part of the same commodity, so the contrary view splitting centrifuged latex from rubber was rejected.

Issues: (i) Whether the circular dated May 28, 1998 stating that field latex and centrifuged latex are one and the same commodity binds the revenue authorities; (ii) whether the circular is illegal or beyond the Board's power under the Kerala General Sales Tax Act, 1963; (iii) whether the earlier contrary view treating centrifuged latex as a different commodity correctly states the law; and (iv) whether the taxing entry covering rubber must be strictly construed in favour of the assessee.

Issue (i): Whether the circular dated May 28, 1998 stating that field latex and centrifuged latex are one and the same commodity binds the revenue authorities.

Analysis: The circular was issued to clarify the treatment of rubber, latex and centrifuged latex under the relevant schedule entry. The statutory scheme gave the Board power to issue orders, instructions and directions for proper administration of the Act. A tax circular meant to secure uniform administration binds the departmental authorities, even if a contrary view had been taken in judicial proceedings, so long as the circular remains in force and has not been withdrawn.

Conclusion: The circular binds the revenue authorities.

Issue (ii): Whether the circular is illegal or beyond the Board's power under the Kerala General Sales Tax Act, 1963.

Analysis: The Board's power under Section 3(1A) of the Kerala General Sales Tax Act, 1963 was held to be wide enough to issue instructions for proper administration and to regulate the working of the statute. The circular merely clarified the statutory entry and did not purport to grant an exemption contrary to the Act. The existence of a separate power of exemption in the Government did not render the clarification invalid.

Conclusion: The circular is not illegal or ultra vires.

Issue (iii): Whether the earlier contrary view treating centrifuged latex as a different commodity correctly states the law.

Analysis: The relevant entry described rubber as including raw rubber, latex and other enumerated forms, using the expression "that is to say", which signifies an exhaustive description of the same commodity. The Court held that the entry did not support splitting the enumerated forms into separate taxable commodities merely because one form had undergone processing. On that construction, the earlier contrary view was inconsistent with the statutory language and with the binding effect of the departmental clarification.

Conclusion: The earlier contrary view does not correctly state the law.

Issue (iv): Whether the taxing entry covering rubber must be strictly construed in favour of the assessee.

Analysis: A taxing provision must be construed strictly, and liability cannot be imposed by implication. Where the entry is reasonably capable of more than one construction, the interpretation favourable to the assessee must prevail. The plain words of the entry were treated as decisive, and the statutory enumeration was read as treating the listed latex forms as part of rubber.

Conclusion: The entry must be strictly construed and the benefit of doubt goes to the assessee.

Final Conclusion: The impugned reassessment and related orders could not stand because the departmental circular remained operative and binding, the clarification was within power, and the relevant taxing entry did not justify the contrary levy position.

Ratio Decidendi: A tax authority's circular issued within its statutory power for uniform administration binds subordinate revenue officers until withdrawn, and a taxing entry must be construed strictly on its plain language, with ambiguity resolved in favour of the assessee.
