2026 INSC 723 | 20 July 2026
What the case was about
These appeals, filed by the Commissioner of Service Tax, Mumbai under Section 35L(b) of the Central Excise Act, 1944 read with Section 83 of the Finance Act, 1994, challenged a common order dated 04.06.2014 passed by the Customs, Excise & Service Tax Appellate Tribunal (CESTAT), West Zonal Bench, Mumbai (paras 1–1.1). The Tribunal had allowed appeals by M/s Bharat Petroleum Corporation Ltd. (BPCL) and M/s Hindustan Petroleum Corporation Ltd. (HPCL) and set aside Orders-in-Original dated 16.08.2012, which had confirmed a service-tax demand against the two oil companies for the periods 2005–2011. The Department’s case was that BPCL and HPCL were rendering “Business Auxiliary Service” as commission agents for Mahanagar Gas Ltd. (MGL) by selling compressed natural gas (CNG) through their retail outlets. CESTAT rejected this, holding the transactions were on a principal-to-principal basis and therefore outside the service-tax net (paras 3.7.2–3.7.3).
The key facts
MGL is engaged in manufacturing and distributing CNG, an excisable good. It entered into agreements with BPCL (dated 30.03.1998) and HPCL (dated 01.06.1999) for the supply and sale of CNG at their petrol pump outlets (para 3.1.1). On the basis that the oil companies were acting as commission agents, the Department issued show-cause notices demanding service tax for 2005–2011 (paras 3.2–3.3.2). The adjudicating authority confirmed the demand, ruling that the relationship was one of principal and agent (paras 3.4–3.6.5). CESTAT reversed these findings, concluding instead that the transactions were genuine sales on a principal-to-principal basis and that no commission was received by the oil companies from MGL (paras 3.7–3.7.3).
The questions before the Court
The Supreme Court framed three interlinked questions:
- Whether the activities of the respondent-Corporations in relation to the sale of CNG provided by MGL at and through their petrol pump outlets fall within the purview of “Business Auxiliary Service” as defined under Section 65(19) read with Section 65(105)(zzb) of the Finance Act, 1994, and consequently attract service-tax liability (para 2).
- Whether the arrangement between MGL and the respondent-Corporations constitutes a “sale” on a principal-to-principal basis or an “agency” on a principal-to-agent basis (para 5).
- Whether the commission or profit margin received by the respondent-Corporations is consideration for rendering a taxable service or merely a trade discount in a sale transaction (see the table of contents, head 22).
What the Court decided and why
The Court identified the core controversy as whether the oil companies were purchasing CNG from MGL as independent buyers for resale to ultimate consumers, or whether they were merely service providers facilitating MGL’s sales to vehicle owners (para 5). It emphasized that the true legal character of the arrangement had to be gathered from the nature of the contract and its terms and conditions, and that the terminology used by the parties was not decisive (para 5.5.1).
Before applying these principles to the facts, the judgment restated the legal distinction between sale and agency. A contract of sale requires the transfer of title to the goods for a price, divesting the seller of control and placing risk on the buyer (paras 5.3–5.3.6). By contrast, an agency relationship is marked by four decisive features: the agent’s legal power to alter the principal’s relations with third parties; the principal’s control over the agent’s conduct; a fiduciary duty; and the agent’s obligation to render accounts for remuneration (para 5.4.7). The essence of agency to sell is that the agent deals with the goods not as his own property but as the property of the principal, who continues to be the owner (para 5.5.1).
The Court then examined CESTAT’s reasoning, which had held that because BPCL and HPCL themselves bought goods from MGL, no marketing service was rendered, and that a fixed retail sale price did not convert a profit margin into commission (paras 3.7.2–3.7.3).
Reading the judgment’s table of contents together with its reasoning, the Supreme Court ultimately resolved the dispute in favour of the Department. It held that title to the CNG did not pass to the oil companies (item (j) within paras 7–7.1.9), that ownership remained with MGL throughout (paras 10–10.3), and that the respondent-Corporations were in fact recipients acting as agents (paras 11–11.3). The Court further ruled that the remuneration was commission rather than a trade discount (paras 9–9.1.2), and that the arrangement fell squarely within the definition of “Business Auxiliary Service” (paras 12–12.2). The formal conclusion and order—which, in light of these findings, allowed the appellant’s challenges, set aside the CESTAT order, and restored the service-tax demand—are contained in paragraphs 13–16.
Why it matters
The judgment brings analytical clarity to the boundary between a taxable agency service and an ordinary sale of goods. By restating the fourfold test for agency—focusing on legal authority over third-party relations, principal control, fiduciary duty, and the obligation to account—the Court provides a practical framework for assessing dealer, distributor, and outlet arrangements across the economy (para 5.4.7). The emphatic reminder that labels are not decisive, and that the true relationship must be gathered from the substance of the contract, reinforces the need for businesses to ensure their agreements reflect the actual economic and legal reality on the ground (para 5.5.1).
For companies in the petroleum, natural gas, and broader retail energy sectors, the ruling carries direct consequences for indirect-tax liability. Where an intermediary does not take title and risk as an independent buyer but operates under the supplier’s ownership, pricing control, and operational direction, the arrangement is properly classified as an agency service rather than a principal-to-principal sale. The case therefore underscores the importance of aligning contractual documentation and business conduct with the true legal nature of the transaction.
