A burgeoning case against Indian businessman Gautam Adani in the US may have gained traction, but extradition remains a challenging and uncertain possibility, according to legal experts.

US prosecutors have obtained strong evidence against Indian billionaire Gautam Adani, including documents found on his nephew’s phone, which could prove that Adani misled investors by failing to disclose bribe payments. The indictment accuses Adani of bribing Indian officials to secure electricity deals for his company, Adani Green Energy, and misleading US investors about the company’s anti-corruption practices. The case against Adani and his colleagues is strong, with experts saying that the evidence will likely make it difficult for them to dispute the allegations. However, it is unlikely that Adani will be extradited to stand trial soon, as it would require cooperation from the Indian government. The US Justice Department has not commented on whether it has made such a request. Adani’s company, Adani Group, has denied the allegations, calling them “baseless.” The US Justice Department is responsible for protecting the integrity of US capital markets, and the case is seen as an important securities enforcement case.
