The next submissions hearing in the extradition trial of Vijay Mallya over alleged fraud and money laundering remains uncertain as the case was on Monday not discussed in a London court due to differences among lawyers. <br/><br/>Chief Magistrate Emma Arbuthnot was listed to hear the case at Westminster Magistrates' Court today, with the 62-year-old embattled liquor baron exempt from attending. <br/><br/>However, the case was not discussed in the court as the lawyers are yet to agree on a mutually convenient date. <br/><br/>The next hearing date is expected within the next few weeks, to be determined internally between the legal counsels and announced at a later date.<br/><br/>The case had been left undecided over the issue of admissibility of evidence presented by the Indian authorities at a hearing earlier this month. <br/><br/>Judge Arbuthnot is set to rule on the issue once Mallya's defence team completes its argument claiming absence of a strong prima facie case and the Crown Prosecution Service, arguing on behalf of the Indian government, responds in favour of the evidence.'<br/><br/>Meanwhile, Mallya's bail on an extradition warrant has been extended until April 2.
