Limitation and evidentiary proof defeated duty demand; grain mill products were construed in their ordinary commercial sense.

Duty demand was found substantially time-barred, as the material on record did not support the contrary limitation finding. The conclusion that the appellants had employed more than 49 workers was unsustainable because it rested on hypothetical reasoning rather than clear evidence, so Item 68 did not apply. The goods were also held to fall within the ordinary commercial meaning of "grain mill products", and a restrictive exclusion was rejected; the exemption contention therefore succeeded. The Collector's orders were set aside and the appeal succeeded.

Issues: (i) whether the demand was barred by limitation; (ii) whether, on the evidence, the appellants could be treated as having employed more than 49 workers so as to bring the goods within Item 68; and (iii) whether the goods fell outside the scope of grain mill products and were therefore liable to duty.

Issue (i): whether the demand was barred by limitation.

Analysis: The demand was substantially beyond time. The material placed did not justify the contrary view taken in the order below.

Conclusion: The demand was largely time-barred in favour of the appellants.

Issue (ii): whether, on the evidence, the appellants could be treated as having employed more than 49 workers so as to bring the goods within Item 68.

Analysis: The finding of employment of more than 49 workers rested on hypothetical reasoning and not on clear evidence. In the absence of reliable material, the worker-strength conclusion could not be sustained.

Conclusion: The appellants were not shown to have employed more than 49 workers, and Item 68 was not attracted.

Issue (iii): whether the goods fell outside the scope of grain mill products and were therefore liable to duty.

Analysis: The expression "grain mill products" was construed in its general sense. On that basis, the goods in question could not be excluded by adopting a restrictive meaning, and the exemption contention had force.

Conclusion: The goods were held to fall within grain mill products, in favour of the appellants.

Final Conclusion: The Collector's orders were set aside and the appeal succeeded.

Ratio Decidendi: Where duty liability depends on a factual threshold and the record does not furnish clear evidence to sustain the threshold, the demand cannot be upheld; exemption expressions must be construed according to their general commercial meaning unless clear evidence supports a narrower exclusion.
