Mukesh Ambani

The 2007 Reliance Petroleum transactions gave rise to several SEBI proceedings. In January 2021, SEBI imposed penalties of ₹150 million on Mukesh Ambani and ₹250 million on RIL in a case involving transactions deemed manipulative. In December 2023, the SAT overturned the relevant sanctions against Ambani and several entities. In a separate aspect, the Supreme Court ruled in May 2026 that exceeding position limits was insufficient to establish the fraudulent or manipulative intent attributed to RIL and ordered reimbursement.

The Indian government and the RIL-BP consortium have been engaged for years in disputes concerning declining production from the KG-D6 block, cost recovery and contractual obligations. In late 2025, Reuters reported a government claim exceeding $30 billion; Reliance publicly disputed the existence of such a "$30 billion claim" and described that characterisation as factually incorrect.

State of the evidence

Disputed

ONGC maintained that some gas from its adjacent blocks had migrated into the KG-D6 block operated by Reliance and that RIL had obtained an undue benefit. The government claimed approximately $1.55 billion in 2016. An arbitral tribunal ruled in RIL's favour in 2018, a decision subsequently upheld by a single judge, but a Division Bench of the Delhi High Court reversed the outcome in February 2025, leading the ministry to issue a demand for approximately $2.81 billion. RIL appealed to the Supreme Court; in 2026, the parties were also exploring mediation.

The land on which Antilia was built had belonged to a trust operating an orphanage.

In July 2025, the Bombay High Court dismissed a further petition challenging the construction and transaction.

In tax litigation concerning donations received by KDA Enterprises, a family company owned 99% by Kokilaben Ambani and 1% by Mukesh Ambani, the tax authority attempted before the Bombay High Court to introduce questions suggesting that the company was merely a vehicle for transferring funds to the family. The Court declined to examine this new theory, which had not been advanced before the lower authorities and lacked a factual basis in the record.

After electoral bond data were published, Qwik Supply Chain emerged among the largest purchasers, with approximately ₹4.1 billion in bonds.
