Excise duty exemption on substantial expansion requires strict factual proof and fair inquiry; matter remanded for fresh adjudication.

Entitlement to excise duty exemption under Notification No. 33/99 turned on disputed proof of substantial expansion of installed capacity on or after the specified date. The record showed unresolved questions about the timing and genuineness of the expansion, the undated machinery supply agreement, the witness statement for which cross-examination was sought, and supporting investment material, while the State Industries report also required scrutiny. Because the original adjudication lacked adequate findings on the issues raised and did not properly address the relevant material, the exemption claim could not be finally sustained on the existing record. The matter required fresh adjudication with cross-examination and examination of all relevant evidence.

Issues: Whether the respondent was entitled to excise duty exemption under Notification No. 33/99 dated 08-07-1999 on the basis that substantial expansion by not less than twenty-five per cent had been undertaken on or after the specified date, and whether the matter required fresh examination.

Analysis: The exemption depended on proof that the installed capacity expansion had taken place on or after 24-12-1997. The record showed unresolved disputes on the timing and genuineness of the expansion, including the need to examine the undated machinery supply agreement, the statement of a material witness whose cross-examination had been sought, and collateral material relating to the claimed investment. The report relied upon from the State Industries authority also required careful scrutiny in view of the disclosed conflict of interest. In these circumstances, the original adjudication was found to be incomplete and without adequate findings on the issues raised in the show-cause notice.

Conclusion: The exemption claim could not be finally sustained on the existing record, and the matter required a fresh adjudication with opportunity of cross-examination and examination of all relevant material.

Ratio Decidendi: Where entitlement to an exemption depends on disputed factual proof of substantial expansion, and the adjudication suffers from inadequate inquiry and denial of material procedural safeguards, the order is liable to be set aside and the matter remanded for fresh decision.
