Concurrent factual findings and exemption burden of proof defeated writ interference with excise demand and penalty.

Concurrent factual findings by the statutory authorities on exemption claims will not be disturbed in writ jurisdiction absent patent infirmity. Where the assessee failed to produce the classification list needed to prove that the goods were unmachined castings, the exemption claim failed, the clearances were treated as dutiable, and the associated duty demand and penalty were sustained. A plea of limitation was also rejected on the basis of suppression of material facts. The burden remained on the assessee to establish the factual foundation for the exemption, and the High Court declined interference with the recorded findings.

Issues: Whether the High Court should interfere in writ jurisdiction with the concurrent factual finding that the assessee failed to prove manufacture and clearance of unmachined castings so as to claim excise exemption, and with the consequential demand and penalty.

Analysis: The authorities below had concurrently found that no classification list had been produced to substantiate the claim that the goods were unmachined castings. On that basis, the exemption claim failed, the clearances were treated as dutiable, and the plea of limitation was rejected in view of suppression of material facts. In writ jurisdiction, the High Court does not reappreciate such concurrent factual findings in the absence of infirmity.

Conclusion: The High Court declined to interfere and upheld the concurrent findings sustaining the duty demand and penalty.

Final Conclusion: The writ petition was not maintainable for upsetting the factual conclusions already recorded by the statutory authorities, and the assessee was left at liberty only to pursue any permissible application before the tribunal on the limited issue of classification list production.

Ratio Decidendi: Concurrent factual findings recorded by the statutory authorities will not be disturbed in writ jurisdiction unless they suffer from a patent infirmity, and the party seeking exemption bears the burden of proving the factual foundation for that claim.
