Natural justice in customs adjudication requires disclosure of adverse material; undisclosed samples and excess penalty invalidated the order.

A quasi-judicial customs authority cannot base an adverse confiscation order on undisclosed samples and information collected after the reply without giving the affected party a fair opportunity to rebut that material; the resulting order was vitiated for breach of natural justice and set aside. The personal penalty was also held to be beyond jurisdiction to the extent it exceeded the statutory maximum under the governing confiscation provision, so the excess portion could not stand. The writ petition therefore succeeded and the impugned customs confiscation and penalty order was quashed.

Issues: (i) whether the customs order was vitiated for breach of natural justice by relying on undisclosed samples and information without giving the petitioners an opportunity to rebut them; (ii) whether the personal penalty imposed exceeded the statutory jurisdiction.

Issue (i): whether the customs order was vitiated for breach of natural justice by relying on undisclosed samples and information without giving the petitioners an opportunity to rebut them.

Analysis: The order was founded not merely on the show-cause notice and the written reply, but also on samples of past imports inspected by the customs authority after the petitioners had replied. Those samples and the inferences drawn from them were not disclosed to the petitioners before the order was made. A tribunal or authority acting quasi-judicially cannot rely on material collected behind a party's back without affording a fair chance to explain or contradict that material. The absence of a statutory procedural code did not dilute the basic obligation to follow the rules of natural justice.

Conclusion: The order was invalid for breach of natural justice and liable to be set aside, in favour of the petitioners.

Issue (ii): whether the personal penalty imposed exceeded the statutory jurisdiction.

Analysis: The personal penalty was imposed under the confiscation provision governing the customs offence, but the court accepted that the maximum personal penalty permissible under the governing provision was only Rs. 1,000. The penalty of Rs. 5,700 was therefore beyond the authority's jurisdiction to the extent of the excess.

Conclusion: The personal penalty was in excess of jurisdiction to the extent it exceeded Rs. 1,000, in favour of the petitioners.

Final Conclusion: The customs confiscation and penalty order could not stand, and the writ petition succeeded with the impugned order set aside.

Ratio Decidendi: A quasi-judicial customs authority cannot found an adverse order on undisclosed material collected behind the affected party's back without giving a fair opportunity to rebut it; such a breach of natural justice vitiates the order, and any penalty imposed beyond the statutory maximum is without jurisdiction.
