Slipper turns to Supreme Court December 4, 2013 - 4:07PM Former parliamentary Speaker Peter Slipper has indicated he will go to the Supreme Court to stop a criminal trial for the alleged misuse of taxpayer funds. Facing three counts of dishonestly causing a loss to the Commonwealth, Slipper on Wednesday failed to secure a stay in proceedings at the ACT Magistrate's Court where he argued that evidence necessary to his defence would breach parliamentary privilege. "I'm not satisfied this assumption is properly made," ACT Chief Magistrate Lorraine Walker replied. Parliamentary privilege may apply but, at this stage, it is purely speculation. But when the court then called for the trial to get under way, counsel for Slipper sought an adjournment, outlining plans to make an "application" to the ACT Supreme Court. The higher jurisdiction is yet to receive an application from Slipper, with the magistrate's court trial on hold pending the outcome. In 2010, Slipper used taxpayer-funded CabCharge vouchers worth more than $900 for three personal journeys to wineries near Canberra, the prosecution alleges. He has pleaded not guilty to the charges. Ms Walker said privileged information was "likely" to form part of evidence in the trial and that the court would consider further applications if such issues arose. But Slipper's application for a stay in proceedings before the trial began was "misconceived or premature," she added.
