Fallen fertiliser mogul Pankaj and his wife Radhika Oswal have been involved in a legal battle with the tax office over a taxation assessment from February 2011.
Their appeal against the assessment relates to a capital gains tax event, linked to shares Oswal held in Burrup Holdings Pty Ltd in the 2007 financial year.
The defence team for Oswal's argued the 1.2 million dollars security payment was unnecessary as the couple's assets in Australia exceed their tax debt.
Nicholas ordered that the 1.2 million dollar payment be provided in a bank cheque or guarantee within 28 days as security for the Australian Taxation Office's costs.

Oswal was owning a fortune of more than 1 billion dollar through the fertiliser empire, which was built on producing the fertiliser ingredient ammonia in a factory in Western Australia's Pilbara region.
The empire collapsed in 2010 and the couple moved to Dubai.
