Australian parliaments can be very noisy and often members behave badly. The Speaker has powers to control their behaviour as part of the Standing Orders. The Speaker can tell a Member to leave the House for one hour. For more serious offences, the Speaker may "name" a Member. The Speaker will say "I name the Honourable Member for X." In Parliament Members are always called by the name of their electorate. The House then votes on a motion to remove the Member for 24 hours. The House also had the power to permanently expel a Member. This happened once to Hugh Mahon in 1920. In 1987 a new law was passed and Members can no longer be expelled from the Parliament.
