Excise valuation and refund principles: arm's length wholesale price governs, and alleged misapplication to facts does not support refund.

Excise valuation under Section 4 required the assessable value to be the wholesale cash price in an arm's length sale in the ordinary course of business. Sales to industrial consumers were not treated as the relevant wholesale market, and on the facts the distributor transactions were found not to be at arm's length because of common management links. The alleged overpayment was therefore not shown to arise from a mistake of law; at most, there was a possible misapplication of the settled principle to the facts. A refund was accordingly not available, particularly since the original assessment was not appealed.

Issues: Whether the assessable value for excise duty was the price charged by the manufacturer to its industrial buyers or to its distributors, and whether the excess duty paid pursuant to the assessing order was refundable on the ground of mistake of law.

Analysis: Section 4 of the Central Excises and Salt Act, 1944 required the duty to be based on the wholesale cash price at the stage of sale in the ordinary course of business and at arm's length. Sales to industrial consumers were not wholesale sales to the trading community, and therefore could not furnish the assessable value. On the facts found by the assessing authority, the transactions with the distributors were not at arm's length because of common management links, so the price realised by the distributors on resale was treated as the relevant wholesale price. The order of assessment was made after the governing law had already been explained by the Supreme Court, and at most there was an alleged misapplication of law to facts, not a mistake of law vitiating the assessment. The petitioners did not challenge the original assessment order by appeal and were taken to have accepted it.

Conclusion: The claim for refund failed, as the duty was not shown to have been paid under any mistake of law and the assessable value adopted by the authorities was not set aside.

Ratio Decidendi: For excise valuation under Section 4 of the Central Excises and Salt Act, 1944, the relevant price is the wholesale cash price arising from an arm's length transaction in the ordinary course of business, and a refund cannot be claimed on the basis of mistake of law where the grievance is only of misapplication of that principle to the facts and the original assessment was not appealed against.
