Statutory sales tax exemption and proof rules: missing declaration does not defeat relief, and departmental opinion cannot override law.

A sales tax exemption for resale turns on satisfaction of the statutory requirements in section 5(2)(a)(ii) of the Orissa Sales Tax Act, and rule 27(2) operates only as a rule of evidence; absence of the declaration does not by itself defeat exemption if the underlying facts are otherwise proved. A rule prescribing the mode of proof for claiming an exemption is within the rule-making power and is not ultra vires where it does not cut down the substantive right. A departmental letter expressing a mistaken legal view cannot absolve liability or create estoppel against the statute.

Issues: (i) whether a registered dealer claiming exemption on sales for resale could be denied exemption merely because the declaration under rule 27(2) was not obtained, and whether a declaration under that rule was always obligatory; (ii) whether rule 27(2) was ultra vires the rule-making power under section 29; (iii) whether a letter issued by the Assistant Sales Tax Officer could absolve the dealer from liability to pay sales tax.

Issue (i): whether a registered dealer claiming exemption on sales for resale could be denied exemption merely because the declaration under rule 27(2) was not obtained, and whether a declaration under that rule was always obligatory.

Analysis: The substantive exemption depended upon the requirements of section 5(2)(a)(ii) of the Orissa Sales Tax Act being satisfied. Rule 27(2) was treated only as a rule of evidence, framed for the benefit of the selling dealer, and not as an exhaustive condition precedent. Exemption could be established by other evidence showing that the transaction fell within the statutory provision.

Conclusion: The absence of a declaration under rule 27(2) did not by itself defeat exemption if the facts necessary to bring the sale within section 5(2)(a)(ii) were otherwise proved; a declaration was not always obligatory.

Issue (ii): whether rule 27(2) was ultra vires the rule-making power under section 29.

Analysis: A rule prescribing the mode of proof for claiming a statutory exemption was within the competence of the rule-making authority. Since the Act itself created the exemption, the rule merely regulated proof of entitlement and did not trench upon the substantive right.

Conclusion: Rule 27(2) was not ultra vires the Orissa Sales Tax Act.

Issue (iii): whether a letter issued by the Assistant Sales Tax Officer could absolve the dealer from liability to pay sales tax.

Analysis: The letter conveyed only an opinion on the legal liability under the sales tax law. There can be no estoppel against statute, and a mistaken view of law expressed by a subordinate officer cannot bind the Department. Relief based on estoppel would arise only in a case of representation of fact, not on a mistaken construction of law.

Conclusion: The letter did not absolve the dealer from liability to pay sales tax if liability otherwise existed under law.

Final Conclusion: The reference was answered by holding that exemption under the Act had to be proved on the statutory requirements, that the evidentiary rule was valid, and that the departmental letter did not prevent lawful assessment.

Ratio Decidendi: A rule framed to prescribe the mode of proof for a statutory exemption is valid if it does not curtail the substantive exemption, and a mistaken departmental opinion on the construction of tax law does not create estoppel against the statute.
