In a landmark ruling, the Supreme Court dismissed a series of appeals from the Uttar Pradesh government, stating that the state cannot impose Value Added Tax (VAT) on natural gas transported through pipelines from Andhra Pradesh. This decision, announced on Friday, reaffirms the earlier judgment issued by the Allahabad High Court in 2012, which invalidated the state’s assessment orders against major companies, including Reliance Industries Limited (RIL), Tata Chemicals, and IFFCO.
The Supreme Court maintained that these transactions represent interstate sales governed solely by the Central Sales Tax (CST) Act. Justice J K Maheshwari, who authored a 94-page judgment for the bench, expressed, “We do not find any valid reason to interfere with the well-reasoned judgment of the High Court… Accordingly, the appeal is dismissed.”
The ruling emphasized India’s federal structure, highlighting the economic disparities among states and advocating for the facilitation of free trade and commerce. The court noted, “It is in this context that the framers of the Constitution have laid down a road map to ensure that the Union government takes over fiscal policies touching upon inter-state or international trade and commerce.”
The judgment underscored that maintaining a balance of powers is essential to preserving the integrity of the federation, warning that any imbalance might undermine the Constitution’s spirit. Furthermore, it asserted that tax laws should be interpreted strictly, with the language of statutes given its natural meaning.
The case revolved around natural gas from the KG-D6 basin off Andhra Pradesh, where the transfer of title occurred at Gadimoga. The gas was then transported across multiple states before reaching buyers in Uttar Pradesh. The state’s tax authorities contended that, since natural gas is fungible and mingles with gas from various sources in pipelines, the transaction should be treated as a local sale subject to a 21 percent state VAT.
However, the Supreme Court dismissed the state’s reasoning, clarifying that a sale is categorized as “inter-state” when it involves the movement of goods across state lines prompted by a contract of sale. The court further mentioned that a 2016 amendment to the CST Act aimed to reinforce this interpretation, clarifying that gas transported via common pipelines is considered an inter-state sale, regardless of co-mingling.
The ruling ultimately protects the principles of federalism and commerce outlined in the Constitution, ensuring that interstate trade remains free from local taxation constraints.
