Proof of exemption cannot be defeated by rigid filing rules, and appeal defects may be cured before dismissal.

Rule 12-A was upheld as a valid evidentiary rule for proving that a sale was not to a consumer under section 3-AA, but it could not be applied so rigidly as to reject exemption certificates filed before assessment merely because they were not enclosed with quarterly returns. An appeal could not be treated as incompetent solely because the memorandum initially omitted or misstated the amount of admitted tax paid, since such a defect was capable of clarification and did not destroy the appeal. The writ petitions were maintainable because they raised a challenge to the validity of Rule 12-A, which the statutory authorities could not finally decide.

Issues: (i) Whether rule 12-A of the U.P. Sales Tax Rules required Form III-A as the exclusive and mandatory mode of proving that a sale was not to the consumer under section 3-AA of the U.P. Sales Tax Act, and whether certificates filed before completion of assessment could be rejected merely because they were not filed with the quarterly returns. (ii) Whether appeals could be dismissed as defective solely because the memorandum of appeal did not originally disclose the amount of admitted tax paid and sought amendment of that statement. (iii) Whether the writ petitions were maintainable despite the availability of alternative statutory remedies.

Issue (i): Whether rule 12-A of the U.P. Sales Tax Rules required Form III-A as the exclusive and mandatory mode of proving that a sale was not to the consumer under section 3-AA of the U.P. Sales Tax Act, and whether certificates filed before completion of assessment could be rejected merely because they were not filed with the quarterly returns.

Analysis: Section 3-AA created a single-point levy and raised a statutory presumption that a sale was to a consumer unless the dealer proved otherwise. Rule 12-A was framed to regulate proof of exemption and, on the reasoning adopted by the Court, it was a valid rule of evidence. It did not authorise the assessing authority to impose an unreasonable time-limit or to reject certificates filed before assessment merely because they were not filed with the quarterly returns. The assessee could rebut the statutory presumption by legally acceptable proof, and the authorities had to examine the certificates on their merits.

Conclusion: Rule 12-A was upheld as valid, but the rejection of the assessee's certificates and the denial of exemption on the ground adopted by the Sales Tax Officer were and unsustainable.

Issue (ii): Whether appeals could be dismissed as defective solely because the memorandum of appeal did not originally disclose the amount of admitted tax paid and sought amendment of that statement.

Analysis: The proviso to section 9(1) required satisfactory proof of payment of the admitted tax before the appeal was entertained, but neither the Act nor the rules required a particular statement in the memorandum in the form insisted upon by the appellate authority. The statement could be clarified, and the appeal could not be treated as incompetent merely because the original memorandum contained an erroneous or incomplete recital. Rule 67(3) also showed that defects in the memorandum were not intended to destroy the appeal itself.

Conclusion: The dismissal of the appeals as defective was invalid and could not be sustained.

Issue (iii): Whether the writ petitions were maintainable despite the availability of alternative statutory remedies.

Analysis: The objection based on alternative remedy was rejected because the challenge included the validity of rule 12-A, a question that the statutory sales tax authorities could not finally and authoritatively decide. The issues also required an early judicial determination in the public interest.

Conclusion: The writ petitions were maintainable and the preliminary objection failed.

Final Conclusion: The assessee succeeded on the challenge to the appellate orders and on the maintainability objection, while the rule itself was upheld; the matter was sent back for fresh disposal of the appeals in accordance with law.

Ratio Decidendi: A statutory rule regulating proof of exemption may prescribe a valid mode of evidence, but it cannot be applied so rigidly as to defeat the substantive right conferred by the Act or to impose an extra-statutory condition not found in the parent legislation.
