George Barber (politician) · Wikipedia (en)
Barber won the seat of Warrego for the Labour Party at the 1907 Queensland state election, defeating the sitting member, Patrick Leahy. Leahy appealed the result based on the fact that Barber was insolvent and the Elections Judge reversed the result and installed Leahy as the member.
