They were the jet-setting, glamorous couple from New Delhi planning to build Australia's biggest home when it all went terribly wrong.
Billionaire Pankaj Oswal and his socialite wife, Radhika, were in the middle of building the $70 million home, dubbed the "Taj-on-Swan" and overlooking the Swan River in the exclusive Perth suburb of Peppermint Grove, when the ANZ bank called in the receivers to take over the Oswals' company, Burrup Fertilisers, now known as Yara Pilbara Fertilisers, claiming they owed more than $100 million.
The case involving the Oswals, who are now based in Dubai, came before the Victorian Supreme Court on Wednesday for pre-trial argument after having been transferred from Western Australia. The civil trial before Justice Michael Sifris is set down to begin on   May 30. 
The Oswals had never been to Western Australia when they arrived in Perth in 2001 with their young daughter, Vasundhara. They set up one of the world's largest liquid ammonia plants five years later in the Burrup Peninsula, 1550 kilometres north of Perth, which at one time employed 500 people.
The Oswals paid $22.7 million for a 6600-square-metre "superblock" from developer Warren Anderson in 2007, and construction of the Indian-style palace home, which was to have seven domes and six bedrooms, began a year later.
The couple planned to spend a reported $47 million building the mega-mansion with a temple, a gym the size of a normal house, an observatory with a revolving roof, a massive swimming pool and parking for 17 cars, which would have made it Australia's biggest home.
Mr Pankaj leased an adjoining block from a neighbour to house his cars, including a white Bentley Continental convertible worth nearly $500,000 and a four-wheel-drive Porsche, while the mansion was being built.
But construction ground to a halt at the end of 2010 when the Oswals and their two daughters suddenly left Australia following an increasingly bitter dispute with ANZ and the receivers.
The couple left behind the unfinished mansion, a $30 million private jet, a number of luxury cars and a $2.7 million luxury cabin cruiser.
Today, more than six years on, the Peppermint Grove shire council has demanded the mansion be demolished by   September 30, claiming it has become a haven for drug users, squatters and vandals.
The council voted to have the building torn down, but Mrs Oswal lodged an appeal with the State Administrative Tribunal which was later dismissed.
The Australian Taxation Office has frozen the Oswals' assets in Australia, including the unfinished mansion, over alleged unpaid taxes involving $186 million said to be owed by Mrs Oswal, which would be one of the biggest personal tax debts in Australian history, and $6.5 million said to be owed by Mr Oswal.
The Tax Office claims the money was owed after shares in Burrup Fertiliser were transferred in 2007 from Mr Oswal to his wife.
The Oswals dispute the size of the tax debt and have denied any wrongdoing.
The case involving the Oswals, the bank and the receivers centres on how in   December 2009, ANZ's $900 million in loans to Burrup were guaranteed by the Oswals' shares. The shareholders were Mr Oswal (30 per cent), Mrs Oswal (35 per cent) and Norwegian ammonia group Yara International (35 per cent).
The bank appointed PPB as receivers to Burrup in   December 2010 amid claims Mr Oswal had been siphoning millions of dollars out of the company for his own personal use. Mr Oswal denied the claims.
The Oswals' shares were sold to Apache Corp and Yara in   January 2011 and the money used to repay the debt to ANZ.
Mr Oswal subsequently sued over the sale of the Burrup plant, while he was accused of breaching his director's duties.
Mr Oswal also complained that the receivers had charged more than $14 million in remuneration fees and $840,000 in expenses during the time Burrup Fertiliser was in receivership from   December, 17, 2010, to   February 2012.
He claimed $2.2 million of the fees and $303,295.39 in expenses were incurred in the final six weeks of the receivership.
