Exemption notification disputes and duty rate issues lie in Supreme Court jurisdiction, not High Court appellate review.

An appeal challenging the applicability of exemption notifications to excisable goods was held to raise a question directly and proximately connected with the rate of duty. Where the real controversy is whether an assessee is covered by an exemption notification, the issue falls within the expression relating to determination of rate of duty for assessment purposes. Accordingly, the proper appellate forum is the Supreme Court under Section 35L of the Central Excise Act, 1944, and not the High Court under Section 35G. The governing principle is that disputes affecting duty incidence through exemption coverage are treated as rate-of-duty questions.

Issues: Whether an appeal under Section 35G of the Central Excise Act, 1944 was maintainable when the controversy turned on exemption notifications and their effect on the rate of duty, and whether such questions lay within the exclusive appellate jurisdiction of the Supreme Court under Section 35L of the Act.

Analysis: The dispute raised by the revenue was not a pure question of classification detached from duty incidence, but one directly concerning the availability of exemption notifications and, therefore, the rate of excise duty payable. The governing principle, as applied from the settled law on questions having a direct and proximate relation to rate of duty, is that where the real controversy concerns whether an assessee is covered by an exemption notification, the matter falls within the expression relating to determination of rate of duty for assessment purposes. On that basis, the appropriate forum is the Supreme Court under Section 35L and not the High Court under Section 35G.

Conclusion: The appeals were not maintainable before the High Court and the remedy lay before the Supreme Court under Section 35L of the Central Excise Act, 1944.

Ratio Decidendi: A dispute directly and proximately concerning the applicability of an exemption notification to excisable goods is a question having relation to the rate of duty for assessment, and an appeal against such a determination lies to the Supreme Court under Section 35L rather than to the High Court under Section 35G.
