Vedanta Oil and Gas Limited has appealed a Delhi High Court single-bench ruling upholding the Ministry of Petroleum’s decision to deny a 10-year contract extension for the CB/OS-2 offshore block. The dispute centers on profit petroleum deductions, clearing the way for state-run ONGC to assume operational control.
NEW DELHI — Energy exploration firm Vedanta Oil and Gas Limited has filed a Letters Patent Appeal before the Division Bench of the Delhi High Court, challenging a single-bench judgment that dismissed its writ petition against the Ministry of Petroleum and Natural Gas and the Directorate General of Hydrocarbons. The court decision, delivered on July 22, 2026, upheld the Union Government's rejection of a 10-year contract extension for the offshore CB/OS-2 oil and gas block off the Gujarat coast.
This legal escalation is critical for energy sector investors and industry stakeholders as the dispute directly impacts asset ownership, operational continuity, and public revenue distribution under India's hydrocarbon production sharing contracts.
High Court Rejects Extension Plea and Mandates Asset Transfer
In a judgment issued by Justice Purushaindra Kumar Kaurav, the Delhi High Court dismissed the writ petition filed by Vedanta Limited challenging the Ministry’s September 19, 2025 rejection order. The court ruled that the government acted within its statutory authority under the 2017 Extension Policy when it denied the 10-year renewal of the Production Sharing Contract (PSC) beyond its original June 29, 2023 expiration date.
The court further affirmed the Ministry's directive instructing state-run Oil and Natural Gas Corporation (ONGC) to take over operations and assets of the CB/OS-2 contract area on an "as is where is" basis. Following the judgment, senior counsel representing Vedanta sought an interim status quo order to preserve operating rights during appeal, but the single bench declined the request.
Core Dispute Over Special Excise Duty Deductions
The legal conflict stems from the implementation of the Special Additional Excise Duty (SAED)—commonly referred to as the windfall tax—imposed on crude petroleum production in 2022. According to court findings, Vedanta Oil and Gas unilaterally deducted approximately $9.33 million (about ₹88 crore) from the Union Government's share of Profit Petroleum between FY23 and FY25 to offset its own SAED tax obligations.
The High Court observed that private exploration contractors hold public natural resources in trust for the nation under the Public Trust Doctrine. The bench held that while private companies have a right to have extension applications evaluated fairly, they hold no automatic or vested right to contract renewals if their conduct compromises public petroleum revenues.
Context and Operational Profile of the CB/OS-2 Block
Located near Suvali off the Surat coast in Gujarat's Cambay Basin, the CB/OS-2 offshore block contains the Lakshmi and Gauri gas fields. Originally awarded in 1998, the field produces approximately 3,400 barrels of crude oil per day alongside 3.4 lakh standard cubic meters of natural gas per day.
Operations at the block are conducted under a joint consortium structure where Vedanta holds a 40% participating interest as operator, ONGC holds 50%, and Invenire Petrodyne retains the remaining 10%. Prior to the rejection, the government had permitted Vedanta Oil and Gas to maintain temporary operations through a series of interim working permits while the formal extension application remained under review.

According to official regulatory filings submitted to BSE Limited and the National Stock Exchange of India under Regulation 30 of SEBI Listing Regulations, the company confirmed the court's judgment and its subsequent legal appeal.
In its statement, the company noted: "The Company has filed a Letters Patent Appeal (LPA) before the Division Bench of the Hon'ble Delhi High Court challenging the said judgment.

Additional procedural updates were confirmed via official notices from the Ministry of Petroleum and Natural Gas and the Directorate General of Hydrocarbons.
Quote Section
"The petitioner is handling public resources of the people of India. The scheme of the PSC is such as would require the private company to give the share of the Government... The Government cannot be held ransom to the whims of a private company, which as per its fancies, interpretations, wishful dreamy adjudications tramples upon the Union's share," stated Justice Purushaindra Kumar Kaurav during the judgment delivery at the Delhi High Court.
Why It Matters
For corporate investors and energy sector analysts, the division bench appeal by Vedanta Oil and Gas will establish crucial precedents regarding the enforceability of government extension policies and fiscal compliance in public-private resource extraction deals.
For domestic fuel consumers and industrial gas buyers, the immediate transition of operations to ONGC ensures that daily production of oil and natural gas from the Gujarat coast remains stable without disrupting regional energy supply chains.
