Advocate-Reviewed Headnote Summary

The dispute in Commissioner of Service Tax, Mumbai v. M/s Bharat Petroleum Corporation Ltd. Etc. was centered on whether Public Sector Oil Marketing Companies—specifically Bharat Petroleum Corporation Limited (BPCL) and Hindustan Petroleum Corporation Limited (HPCL)—were liable to pay service tax on the margins earned from distributing Compressed Natural Gas (CNG)?


The Mahanagar Gas Limited (MGL) manufactured CNG and distributed it to consumers through retail outlets owned and operated by BPCL and HPCL.


The Service Tax Department issued demand notices asserting that the oil PSUs provided infrastructure, site facilities, and manpower to market CNG, rendering their earnings taxable as a "Business Auxiliary Service" under Section 65(19) read with Section 65(105)(zzb) of the Finance Act, 1994.

The Customs, Excise and Service Tax Appellate Tribunal (CESTAT) set aside the tax demands, ruling that the arrangement was a principal-to-principal sale of goods on which Value Added Tax (VAT) had already been paid.


The Supreme Court, while allowing the Revenue's appeals, set aside the CESTAT order, and restored the original tax demand and observed that calling a transaction a "sale" or labeling terms as "principal-to-principal" in isolated contract clauses does not alter its true legal character.

The jural relationship must be gathered by examining the agreement as a whole, focusing on where legal control and title reside.


On the decisive factor, where that MGL retained complete ownership of the CNG and the processing equipment at the pump sites at all times, the Apex Court observed that the BPCL and HPCL had no power to alter retail prices or keep unsold stock upon contract termination, and any remaining gas had to be returned to MGL. This lack of dominion meant no title ever passed to the PSUs (Public Sector Undertakings) and that MGL retained the ownership and control over the price.


The Apex Court further rejected the argument that discharging state VAT on final retail sales excluded service tax liability. Providing site facilities, compressors, and trained staff to promote and execute sales on behalf of a principal constitutes a distinct, taxable auxiliary service rendered to the principal.


"Business Auxiliary Service is any commercial assistance, support, or activity performed by a third party to help another business market, promote, or sell its goods and services."


The Apex Court held that the legal relationship between MGL and the oil PSUs (Public Sector Undertakings) was strictly that of "Principal and Agent" rather than "Seller and Buyer". -


Because title, ownership, risk, and price-fixing authority over the gas remained entirely with MGL, the profit margins retained by BPCL and HPCL constituted pre-arranged agency commission rather than trade discounts, bringing the activity squarely within the taxable scope of "Business Auxiliary Services".


BENCH: Justice Aravind Kumar and Justice N.V. Anjaria.
