Appellate jurisdiction and retrospective tax rate changes under Bombay sales tax law, with machinery purchases excluded from form 15 breach computation.

Under the unamended appellate provision, the appellate authority could deal only with the subject-matter of the pending appeal and could not travel beyond it, though it could decide any liability issue properly arising within that scope. Because the appeal concerned liability under section 14, the retrospective substitution of section 14(2A) permitted application of the enhanced purchase tax rate. The pro rata method for form 15 contraventions applied only to raw-material purchases and not to machinery purchases, so the breach was confined to raw-material purchases and not the larger combined figure.

Issues: (i) Whether, under the unamended section 55(6) of the Bombay Sales Tax Act, 1959, the appellate authority could enhance the quantum of taxable purchases and the rate of purchase tax in an assessee's pending appeal; (ii) whether the retrospective substitution of section 14(2A) of the Bombay Sales Tax Act, 1959 empowered enhancement of the rate of purchase tax in such appeal; (iii) whether the contravention of form 15 declarations had to be worked out by including machinery purchases in the pro rata method.

Issue (i): Whether, under the unamended section 55(6) of the Bombay Sales Tax Act, 1959, the appellate authority could enhance the quantum of taxable purchases and the rate of purchase tax in an assessee's pending appeal.

Analysis: The unamended provision conferred appellate power only in relation to the subject-matter of the appeal. Its scope was narrower than the later amended provision and did not authorise the appellate authority to travel outside the points raised in the appeal or to disturb matters wholly unconnected with the dispute. At the same time, where the appeal itself put in issue the computation of liability under section 14, the appellate authority could determine that issue even if its determination resulted in an enhancement within the scope of the appeal. The appeal here was pending when the amendment came into force, so the old provision governed the extent of power.

Conclusion: The appellate authority had jurisdiction to enhance the quantum of purchases in relation to the issue raised in appeal, but the order enhancing the figure from Rs. 3,52,597 to Rs. 7,69,246 was wrong on the facts and law.

Issue (ii): Whether the retrospective substitution of section 14(2A) of the Bombay Sales Tax Act, 1959 empowered enhancement of the rate of purchase tax in such appeal.

Analysis: The appellate authority had to apply the law as it stood at the time of decision where the statute operated retrospectively. Since the substituted provision was made retrospective, the applicable purchase tax rate was not confined to the earlier rate if the subject-matter of the appeal included the tax liability under section 14. The challenge in appeal necessarily covered the amount of tax payable, which included the rate applicable to the taxable turnover.

Conclusion: The appellate authority possessed jurisdiction to apply the enhanced rate of purchase tax by reason of the retrospective operation of section 14(2A).

Issue (iii): Whether the contravention of form 15 declarations had to be worked out by including machinery purchases in the pro rata method.

Analysis: The pro rata method was applicable to raw materials where separate identification of use was not possible. Machinery purchases stood on a different footing and were not part of the same basis for working out breach of the form 15 declarations. The method adopted by the department and accepted below wrongly treated machinery purchases as though they were part of the same pool as raw materials.

Conclusion: The contravention of form 15 declarations was confined to raw-material purchases of Rs. 3,52,597 and did not extend to the larger figure including machinery purchases.

Final Conclusion: The reference was answered by sustaining appellate jurisdiction on the legal issues, while correcting the excess computation of breach under form 15 and leaving consequential relief to administrative implementation.

Ratio Decidendi: Under an unamended appellate provision confined to the subject-matter of the appeal, the appellate authority may decide any issue arising in that subject-matter, including one that increases liability, but cannot travel beyond the appeal or treat distinct categories of purchases as one for the purpose of computing contravention.
