Mr Burke and his co-accused, former stockbroker David John Massey, appeared in person in the WA Supreme Court today. They were formally arraigned on four charges each regarding offences alleged to have occurred between April 12 and 26, 2006. Mr Burke is accused of possessing information about listed fibre optic network provider Amcom Telecommunications that was not available to the general public when he, through Mr Massey, bought 200,000 shares in the company. Mr Massey stands accused of aiding and abetting the offence. Both men reiterated earlier pleas of not guilty and are scheduled to stand trial from March 24 until April 17 next year. The length of the trial may be shortened if the parties can deal with evidence-related issues, including phone taps, in the meantime. The pair's bail was extended until a status conference on October 3, with each providing a personal undertaking of $10,000. Outside court Mr Burke said he hadn't done anything wrong. ``And I'm confident that justice will prevail. He said the case was a continuation of a ``witch hunt" against him by the Corruption and Crime Commission.
