Mutuality of interest governs related-person valuation; common shareholding and commercial arrangements alone do not displace transaction value.

Mere common shareholding, common directors, sole-selling arrangements, shared promotional expenses, or contractual restrictions do not by themselves establish related-person status under Central Excise valuation rules. The governing test is mutuality of interest in each other's business, requiring reciprocal interest rather than a one-sided commercial or managerial connection. On the facts, the entities dealt on principal-to-principal terms and the revenue material was insufficient to displace the declared transaction value. The appellants were therefore not related persons, the assessable value could not be re-fixed on the impugned basis, and the demand, interest, and penalties founded on rejection of transaction value failed.

Issues: Whether the appellants were related persons for the purpose of valuation under the Central Excise law, so as to justify rejection of the transaction value and assessment under the valuation rules.

Analysis: The dispute turned on whether inter-connected undertakings are automatically related persons or whether, on the facts, there was mutuality of interest in the business of each other. The governing principle applied was that mere common shareholding, common directors, sole-selling arrangements, shared promotional expenses, or contractual restrictions do not by themselves establish the reciprocal interest required by the law. The expression that the parties must have interest, directly or indirectly, in the business of each other requires mutuality, and not a one-sided commercial or managerial connection. On the facts, the relationship between the entities remained that of commercial arrangements on principal-to-principal terms, and the revenue material was insufficient to displace the declared transaction value.

Conclusion: The appellants were not related persons for valuation purposes, and the assessable value could not be determined on the basis adopted in the impugned order.

Final Conclusion: The demand, interest, and penalties based on rejection of the transaction value were unsustainable, and the appeals succeeded.

Ratio Decidendi: Mutuality of interest under the excise valuation provisions requires reciprocal, not merely one-sided, interest in each other's business; absent such mutuality, inter-connected undertakings cannot be treated as related persons merely on the basis of shareholding, common management, or commercial arrangements.
