The 1992 by-election is remarkable for a number of reasons : It was caused by Bob Hawke 's retirement from parliament ; it had a record twenty-two candidates standing ; it was won by an independent ; the results were thrown out as the winner , Phil Cleary , was on unpaid leave from the state education system ( the Australian Constitution forbids people employed by the Crown from standing for election ) .
However he was on unpaid leave from the state education system and the Australian Constitution forbids people employed by the government from standing for election .
