Preventive detention for alleged customs undervaluation fails without statutory valuation compliance, proof, and a live link to the detention need.

Non-supply of relied upon documents did not vitiate detention where the disputed papers originated from the detenu and were already part of his own submissions, so no prejudice to an effective representation was shown. Preventive detention based on alleged undervaluation of imported goods was unsustainable because valuation under the Customs Act and the 2007 Valuation Rules had not been shown to be followed, and mere suspicion or a confession could not replace the prescribed statutory procedure and proof. Unexplained delay in passing the detention order further weakened the live link between the alleged conduct and the need for detention, and the order was quashed.

Issues: (i) Whether non-supply of the relied upon documents and illegible copies of documents that had been produced by the detenu during investigation vitiated the detention order; (ii) whether the alleged undervaluation of imported goods could sustain preventive detention without compliance with the valuation procedure under the Customs Act, 1962 and the Customs Valuation (Determination of Value of Imported Goods) Rules, 2007; (iii) whether the delay in passing the detention order rendered it unsustainable.

Issue (i): Whether non-supply of the relied upon documents and illegible copies of documents that had been produced by the detenu during investigation vitiated the detention order.

Analysis: The documents complained of formed part of the bills of entry and other papers submitted by the detenu himself during investigation. The Court held that where the disputed papers emanate from the detenu and are already part of his own submissions, non-supply of those documents or of legible copies does not, by itself, prejudice the right to make an effective representation so as to invalidate the detention.

Conclusion: The contention based on non-supply of documents was rejected and the detention order was not vitiated on that ground.

Issue (ii): Whether the alleged undervaluation of imported goods could sustain preventive detention without compliance with the valuation procedure under the Customs Act, 1962 and the Customs Valuation (Determination of Value of Imported Goods) Rules, 2007.

Analysis: The Court examined the statutory scheme governing valuation of imported goods and noted that valuation must follow the transaction value principle, with rejection of declared value only on cogent reasons and by resort to the prescribed sequential valuation mechanism. It further noted the safeguards under the Customs Act, including notice, speaking assessment, and appellate remedy. As the record did not show scrupulous compliance with the valuation rules or any satisfactory material proving under-valuation, mere suspicion could not justify invocation of preventive detention. Reliance on a confessional statement was also found insufficient to displace the statutory requirement of proof and procedure.

Conclusion: The preventive detention could not be sustained on the basis of alleged undervaluation when the statutory valuation procedure had not been shown to have been followed.

Issue (iii): Whether the delay in passing the detention order rendered it unsustainable.

Analysis: The impugned detention order was passed substantially later than the alleged incident, and the Court found no satisfactory explanation for the delay. In preventive detention matters, unexplained delay weakens the live link between the alleged conduct and the need for detention.

Conclusion: The unexplained delay furnished an additional ground to invalidate the detention order.

Final Conclusion: The detention order was held unsustainable in law and was quashed, resulting in the detenu's immediate release unless required in any other case.

Ratio Decidendi: Preventive detention for alleged customs undervaluation cannot rest on mere suspicion or an unverified confession when the statutory valuation procedure, notice requirements, and appellate safeguards under the Customs Act have not been followed; unexplained delay further undermines the detention.
