Exemption classification for tele-communication cables fails where adverse material is incomplete and not fairly disclosed to the assessee.

An exemption classification under a fiscal notification cannot rest on incomplete or undisclosed material that is not fairly put to the affected party. Here, the cables were treated as tele-communication cables eligible for the concessional rate under Notification No. 50 of 1968, supported by the manufacturing approval and the overall record. The adverse classification was unsustainable because the department relied on incomplete extracts without giving a full opportunity to meet them, and denial of cross-examination weakened the evidentiary basis.

Issues: Whether the petitioners' PVC underground and overground tele-communication cables were entitled to the concessional rate of excise duty under Notification No. 50 of 1968 and whether the authorities below could deny the benefit of exemption by relying on incomplete extracts without affording a fair opportunity to meet that material.

Analysis: The exemption notification under Rule 8 of the Central Excise Rules, 1944 granted a concessional rate for underground and overground tele-communication wires and cables, while the residuary entry covered other electric wires and cables. The impugned order was founded mainly on extracts from letters of departmental authorities, but the extracts were incomplete, their source and context were not established, and the petitioners were not given the full material or an effective opportunity to test it. The denial of cross-examination further weakened the evidentiary basis of the adverse finding. On the other hand, the letter approving manufacture for underground cables and the overall record supported the petitioners' claim that the goods were tele-communication cables falling within the exempted category.

Conclusion: The petitioners were entitled to the benefit of Notification No. 50 of 1968, and the excise duty applicable to the goods was only 5% ad valorem. The adverse classification and denial of refund were unsustainable.

Final Conclusion: The classification adopted by the excise authorities was set aside and the petitioners were held entitled to refund of the excess duty paid on the disputed cables.

Ratio Decidendi: An exemption classification under a fiscal notification cannot be sustained where the adverse decision rests on undisclosed or incomplete material not fairly put to the affected party; if the goods fall within the exempted description, the concessional rate must be allowed.
