States Cannot Levy VAT on Inter-State Natural Gas Sales: SC

In a significant ruling affirming the principles of fiscal federalism, the Supreme Court held that the State of Uttar Pradesh lacks the jurisdiction to impose Value Added Tax (VAT) on the sale of natural gas that constitutes inter-State trade under the Central Sales Tax Act, 1956. A division bench comprising Justice J.K. Maheshwari and Justice Atul S. Chandurkar dismissed the appeals filed by the State of Uttar Pradesh, reinforcing that the movement of gas through common carrier pipelines from one State to another remains an inter-State transaction, regardless of physical co-mingling.

Supreme Court Upholds Inter-State Character of Gas Sales

The Court clarified that once a transaction satisfies the conditions of Section 3 of the Central Sales Tax Act, 1956, it falls within the exclusive domain of the Union Government. The bench observed that the 'delivery point' fixed at Gadimoga, Andhra Pradesh, governed the transfer of title and risk, making the subsequent movement to Uttar Pradesh a clear instance of inter-State trade. The Court rejected the State's argument that the fungible nature of gas or its co-mingling in pipelines converted the transaction into an intra-State sale.

Clarification on Section 3 and the 2016 Amendment

Addressing the 2016 amendment to the Central Sales Tax Act, 1956, which added Explanation 3 to Section 3, the Court held it to be clarificatory and retrospective. The Court, in its reasoning, observed: "The amendment to Section 3 of the CST Act by way of Explanation 3 does not effectively alter its scope, rather simply reflects the statutory intent to clarify inter-state transactions. Furthermore, considering its clarificatory nature, unless expressly provided to be prospective in nature, it has to be read to be effective from the date the main provision came into force."

Background: The Dispute over Gas Taxation

The matter arose from assessment orders passed by the Uttar Pradesh commercial tax authorities levying VAT at 21% on natural gas supplied by Reliance Industries Limited from the KG-D6 basin (off the coast of Andhra Pradesh) to various buyers in Uttar Pradesh. The State contended that because the gas was co-mingled in GAIL's common carrier pipelines and only 'ascertained' or re-metered at delivery points within UP, the sale took place inside the State under Section 4 of the Central Sales Tax Act, 1956 and the Uttar Pradesh Value Added Tax Act, 2008.

The respondents argued that the movement of gas from Andhra Pradesh to Uttar Pradesh was occasioned by a pre-existing Gas Sales and Purchase Agreement (GSPA), satisfying the criteria for inter-State sale under Section 3(a) of the Central Sales Tax Act, 1956. They relied on State of Andhra Pradesh v. NTPC and Hyderabad Engineering Industries v. State of A.P. ( "(2011) 4 SCC 705": 2011 CaseBase(SC) 98) to show that the place where property passes is irrelevant if the sale occasions inter-State movement.

Judicial Rationale on Federal Taxation Limits

The Court emphasized that the Constitution of India, 1950 maintains a principle of mutual exclusivity in taxing powers. It relied on the landmark Seven-Judge Bench decision in Bengal Immunity Co. Ltd. v. State of Bihar to underscore that the situs of a sale is irrelevant to its inter-State character. The bench further noted that the State of UP had already issued 'Form-C' to the buyers, acknowledging the inter-State nature of the trade, and could not now "blow hot and cold."

Regarding the State's invocation of the 'Public Trust Doctrine,' the Court noted that while the Union holds natural resources in trust, this doctrine cannot be used to override the constitutional division of taxing powers. The Court concluded that the Uttar Pradesh Value Added Tax Act, 2008 cannot apply to transactions that are constitutionally protected as inter-State trade.
