Technical evidence required for furnace classification before annual production capacity can be determined under excise law.

Annual production capacity under Section 3A of the Central Excise Act, 1944 could not be conclusively determined without technical assistance where the furnace classification as batch type or pusher type was disputed. The record showed competing material from a Chartered Engineer's certificate, technical literature, and physical inspection, and the matter required examination by a technical authority or an engineer versed in furnace installations before a final finding could be recorded. The capacity determination was therefore set aside and remanded for fresh decision after hearing the assessee.

Issues: Whether the annual production capacity under Section 3A of the Central Excise Act, 1944 could be determined without taking the assistance of a technical authority to ascertain whether the furnace was batch type or pusher type.

Analysis: The capacity determination turned on the correct classification of the furnace. The record showed that the assessee disputed the finding that the furnace was pusher type and relied on a Chartered Engineer's certificate, while the adjudicating authority relied on technical literature and physical inspection. In the circumstances, the matter required examination by a technical authority or engineer well versed with furnace installations before a conclusive finding could be recorded.

Conclusion: The capacity determination was set aside for fresh examination with the assistance of a technical authority, and the matter was remanded to the jurisdictional Commissioner for a fresh decision after giving the assessee an opportunity of hearing.
