Natural justice requires a fair opportunity before duty confirmation and penalty, even where show-cause notice is waived.

An adjudication confirming duty and imposing penalties without a meaningful prior opportunity of defence is unsustainable, even if the assessee had waived show-cause notice and debited duty. The Tribunal applied the principle that natural justice requires prior intimation of the proposed grounds and a fair chance to respond before duty confirmation and penalty proceedings can stand. Because the order rested on allegations of shortage and penal consequences were imposed without such opportunity, the adjudication was treated as vitiated and the duty demand and penalties did not survive.

Issues: Whether the impugned adjudication and penalties could stand when no show cause notice was issued and the assessee had waived notice and debited duty, and whether the proceedings were vitiated by violation of natural justice.

Analysis: The appeal turned on the requirement of a show cause notice and a fair opportunity before confirming duty and imposing penalty. The prior waiver of notice did not cure the denial of a meaningful opportunity where the order was sustained on allegations of shortage and penalties were imposed under the penal provisions. The Tribunal applied the principle that natural justice is not an empty formality and that penalty proceedings require prior intimation of the proposed grounds and a reasonable opportunity of representation. In these circumstances, the impugned order was found unsustainable.

Conclusion: The order was held to be vitiated by violation of the principles of natural justice and the penalties and duty confirmation did not survive.

Ratio Decidendi: A waiver of show cause notice does not dispense with the requirement of natural justice, and an adjudication imposing duty and penalty without a fair opportunity of defence cannot be sustained.
