The Supreme Court of India addressed whether the activities undertaken by public sector oil companies (BPCL and HPCL) in selling Compressed Natural Gas (CNG) supplied by Mahanagar Gas Limited (MGL) through their retail petrol pump outlets qualify as a “Business Auxiliary Service” under the Finance Act, 1994, thereby attracting service tax liability. Setting aside the common order of the Customs, Excise & Service Tax Appellate Tribunal (CESTAT) which had favored the oil corporations, the Supreme Court held that the contractual arrangement between MGL and the respondent-Corporations creates a “Principal-Agent” relationship rather than an outright “Principal-to-Principal” sale. Consequently, the Court ruled that the profit margins or commissions received by BPCL and HPCL constitute consideration for marketing and promotional services rendered as commission agents, making them fully liable to pay service tax.
- Nature of the Controversy: The core issue centered on whether the transactions involving the supply and sale of CNG through retail outlets owned by BPCL and HPCL were outright sales of goods on a “Principal-to-Principal” basis or service provision under a “Principal-Agent” framework.
- Evaluation of Agreements: Upon examining the contractual terms between MGL and the respondent-Corporations, the Court noted that MGL retains absolute ownership over the equipment and the gas stocks. Unsold stocks upon termination must be returned to MGL, and retail prices are strictly fixed and regulated by MGL.
- Distinction Between Sale and Agency: Relying on statutory definitions and established jurisprudence (such as Hafiz Din Mohammad and Future Gaming Solutions), the Court reiterated that the essence of a sale is the transfer of title and risk for a price. Because ownership and risk of the CNG do not pass to the oil corporations at any point prior to final consumer dispensation, no “sale” occurs between MGL and the corporations.
- Role as Commission Agents: The agreements explicitly provide for the payment of a “commission/profit margin” per kilogram of CNG sold. The Court concluded that the respondent-Corporations act as facilitators and commission agents who promote and market MGL’s products, placing their operations squarely within the definition of “Business Auxiliary Service” under Section 65(19) of the Finance Act.
- Final Order: The Supreme Court allowed the appeals filed by the Revenue, set aside the CESTAT order dated June 4, 2014, and restored the original demand orders passed by the adjudicating authority, confirming the service tax liability along with applicable interest and penalties.
