Natural justice and customs valuation rules require cross-examination and statutory valuation methods before enhancing scrap value.

Denial of cross-examination of the investigating officer and forensic officer was treated as a breach of natural justice because the appellants needed to test the authenticity and handling of the pen drive evidence; the adjudication was therefore unsustainable. The valuation enhancement of aluminium scrap was also found legally unsupportable because the Customs Valuation Rules require rejection of declared value and re-determination through the prescribed statutory sequence, including contemporaneous import data, rather than a prime-metal-linked discount model based on assumed correlation with LME prices. The matter was remitted for fresh adjudication with cross-examination allowed and the import evidence examined on merits.

Issues: (i) Whether denial of cross-examination of the investigating officer and forensic officer vitiated the adjudication for breach of natural justice; (ii) whether the enhancement of assessable value of aluminium scrap by adopting a prime-metal-linked discount method, instead of the prescribed valuation sequence and contemporaneous import data, was sustainable.

Issue (i): Whether denial of cross-examination of the investigating officer and forensic officer vitiated the adjudication for breach of natural justice.

Analysis: The appellants questioned the authenticity and handling of the pen drive, including the alleged re-examination and retrieval of additional files. In such circumstances, the witnesses connected with the investigation and forensic examination were material to test the veracity of the evidence. The refusal to permit cross-examination deprived the appellants of an effective opportunity to challenge the incriminating material and caused prejudice.

Conclusion: The denial of cross-examination amounted to a violation of natural justice and rendered the adjudication unsustainable.

Issue (ii): Whether the enhancement of assessable value of aluminium scrap by adopting a prime-metal-linked discount method, instead of the prescribed valuation sequence and contemporaneous import data, was sustainable.

Analysis: The Customs Valuation Rules require rejection of the declared value and re-determination only by following the statutory sequence, including identical goods, similar goods, deductive methods and, if necessary, the residuary method consistent with Section 14. The adjudication did not address the appellants' contemporaneous import data, but instead adopted a valuation model based on a presumed correlation between aluminium scrap prices and LME prime metal prices. The record also did not show any formal public study by LME establishing such linkage. The valuation method therefore lacked legal support.

Conclusion: The value enhancement and consequential duty and penalties were not sustainable in law.

Final Conclusion: The matter was sent back for fresh adjudication after granting the appellants an opportunity to cross-examine the relevant witnesses and to have their contemporaneous import evidence examined on merits.

Ratio Decidendi: Where the adjudication rests on disputed forensic material and valuation is rejected without following the statutory sequence under the Customs Valuation Rules, denial of cross-examination and adoption of an unsupported pricing methodology vitiate the order.
