"Whereas Mr Ambani's investments were worth more than USD 7 billion in 2012, they are now worth USD 89 million, and his net worth is zero once his liabilities are taken into account... Quite simply, he was a wealthy businessman, now he is not," said his barrister Robert Howe.
The banks' counsel called Ambani's claims into question and repeatedly referred to his "lavish lifestyle", involving access to 11 or so luxury cars, a private jet, a yacht and rent-free access to the exclusive Seawind penthouse in South Mumbai.
"So, Mr Ambani's assertion is that he is massively personally insolvent, is bankrupt. Has he filed for bankruptcy in India," questioned Justice David Waksman during the course of the half-day hearing.
