Related person test and windmill exemption: mutuality of interest must be proved, and wind turbine components may qualify for exemption.

Mutuality of interest is required to treat a buyer as a related person under section 4(3)(b) of the Central Excise Act, 1944; common holding, related-party disclosure, interest-bearing loans and shared staff costs, without positive evidence of reciprocal business interest, are insufficient, so the declared transaction value cannot be rejected on that ground. Exemption under Notification No. 6/2006-CE for wind operated electricity generators extends to the integrated windmill assembly and its major components, including bearings used in generation equipment, where the notification is read with the statutory entry and departmental clarification. The demand, penalties and denial of exemption do not survive.

Issues: (i) Whether the appellant and the buyer were related persons under section 4(3)(b) of the Central Excise Act, 1944 so as to warrant rejection of the declared transaction value; and (ii) whether the bearings cleared for use in wind operated electricity generators were entitled to exemption under Notification No. 6/2006-CE dated 01/03/2006.

Issue (i): Whether the appellant and the buyer were related persons under section 4(3)(b) of the Central Excise Act, 1944 so as to warrant rejection of the declared transaction value.

Analysis: The existence of common holding, related party disclosure in accounts, a loan arrangement carrying interest, and cost-sharing of staff expenses did not by itself establish that the parties had direct or indirect interest in each other's business. The decisive requirement under clause (iv) was proof of mutuality of interest, which had to be supported by positive evidence. Business transactions conducted on commercial terms, including interest-bearing finance and recoveries of shared costs, were insufficient to treat the parties as related persons.

Conclusion: The parties were not related persons and the declared transaction value could not be rejected on that ground; this issue was decided in favour of the appellant.

Issue (ii): Whether the bearings cleared for use in wind operated electricity generators were entitled to exemption under Notification No. 6/2006-CE dated 01/03/2006.

Analysis: The notification had to be read in the context of the statutory entry and the departmental circular clarifying that the wind operated electricity generator comprised the complete windmill setup, including its major components and sub-systems such as rotor, nacelle, generator and related parts. The exemption could not be confined narrowly to the generator alone. Bearings used in the windmill assembly for generation of electricity fell within the scope of the exempted entry.

Conclusion: The bearings used in wind operated electricity generators were covered by the exemption; this issue was decided in favour of the appellant.

Final Conclusion: The demand, penalties and denial of exemption did not survive, and the appeal was allowed.

Ratio Decidendi: To reject the declared value under section 4(3)(b), the revenue must prove mutuality of interest by positive evidence, and an exemption entry for wind operated electricity generators extends to the integrated windmill assembly and its components where the notification and departmental clarification so indicate.
