Court Rules Vedanta’s Deduction of Special Additional Excise Duty from Government’s Profit Petroleum Share Violated Extension Policy and Public Trust Doctrine; Application for Contract Extension Lawfully Denied
In a landmark judgment delivered on July 22, 2026, the Delhi High Court dismissed Vedanta Limited’s petition challenging the Ministry of Petroleum and Natural Gas (MoPNG)’s decision to reject its application seeking a 10-year extension of its Production Sharing Contract (PSC) for the offshore CB/OS-2 Block in Gujarat. The Court upheld the government’s authority to deny extension on grounds of Vedanta’s unilateral deduction of Special Additional Excise Duty (SAED) from the government’s share of profit petroleum, deeming such conduct a breach of contract and constitutional obligations under the Public Trust Doctrine.
The PSC, originally signed in 1998 between the Government of India, ONGC, Vedanta’s predecessor, and Tata Petrodyne Ltd., governs exploration and production in the offshore block. Under the contract and the MoPNG’s Extension Policy notified in 2017, Vedanta applied in June 2021 for a 10-year extension beyond June 2023. However, the government rejected the extension in September 2025, primarily citing Vedanta’s act of deducting approximately INR 88 crores (USD 9.33 million) from the government’s profit petroleum share to adjust for SAED payable to the Central Excise Department.
The Court analyzed the contractual provisions, particularly Article 16.7 governing changes in Indian laws affecting economic benefits, and found that Vedanta’s unilateral adjustment without good faith consultations or judicial adjudication was impermissible. The PSC requires joint consultation and arbitration for such matters to maintain economic benefits without unilateral action. Vedanta’s delay in paying the deducted amount further compounded the breach.
Importantly, the Court affirmed that the Extension Policy constitutes a statutory framework binding on the parties and must be interpreted in light of the Public Trust Doctrine under Article 297 of the Constitution. This doctrine entrusts the government as a trustee of natural resources for the people of India, mandating fair, transparent, and accountable management of public wealth. The Court held that grounds for rejecting extension applications are not limited to technical criteria but also include conduct affecting public interest and the government’s sovereign rights.
Rejecting Vedanta’s argument that the application should be assessed based on facts prevailing at the time of submission, the Court held that subsequent events up to the date of decision are relevant, especially when they affect the government’s interests. It also dismissed claims of legitimate expectation arising from interim extensions, noting that such extensions explicitly did not confer any right or indication of favorable consideration.
The Court underscored the constitutional principle that State action in contractual matters must conform to Article 14’s guarantee against arbitrariness, and that the government’s decision to reject the extension was rational, reasoned, and in furtherance of public interest. The judgment reiterates that private parties exploiting public natural resources must act in consonance with constitutional duties and cannot subvert government shares or act as judge in their own case.
This ruling is significant as it reinforces the government’s supervisory role over natural resource contracts, ensures adherence to public trust principles, and clarifies the scope and limitations of contract extensions under the Extension Policy. It sends a clear message that contractual privileges involving national resources are subject to constitutional scrutiny and that any breach impacting government revenue or public interest will be viewed gravely.
Bottom Line:
A petition seeking an extension of a Production Sharing Contract (PSC) concerning natural resources is maintainable. However, the extension is not an automatic right and must be adjudicated in light of applicable policies, especially considering the Public Trust Doctrine.
