Parliament of Australia - Procedure

Procedure

Each of the two Houses elects a presiding officer. The presiding officer of the Senate is called the President; that of the House is the Speaker. Elections for these positions are by secret ballot. Both offices are conventionally filled by members of the governing party, but the presiding officers are expected to oversee debate and enforce the rules in an impartial manner.

The Constitution authorises Parliament to set the quorum for each chamber. The quorum of the Senate is one-quarter of the total membership (nineteen); that of the House of Representatives is one-fifth of the total membership (thirty). In theory, if a quorum is not present, then a House may not continue to meet. In practice, members usually agree not to notice that a quorum is not present, so that debates on routine bills can continue without other members having to be present. Sometimes the Opposition will "call a quorum" as a tactic to annoy the Government or delay proceedings, particularly when the Opposition feels it has been unfairly treated in the House. It is the responsibility of the Government whips to ensure that when a quorum is called, enough Government members are present to make up a quorum.

Both Houses may determine motions by voice vote: the presiding officer puts the question, and, after listening to shouts of "Aye" and "No" from the members, announces the result. The announcement of the presiding officer settles the question, unless at least two members demand a "division," or a recorded vote. In that case the bells are rung throughout Parliament House summoning Senators or Members to the chamber. During a division, members who favour the motion move to the right side of the chamber, whereas those opposed move to the left. They are then counted by the "tellers" (Government and Opposition whips), and the motion is passed or defeated accordingly. In the Senate, in order not to deprive a state of a vote in what is supposed to be a states' house, the President is permitted a vote along with other Senators (however, that right is rarely exercised); in the case of a tie, the President does not have a casting vote and the motion fails. In the House of Representatives, the Speaker does not vote, except in the case of a tie (see casting vote).

In the event of conflict between the two Houses over the final form of legislation, the Constitution provides for a simultaneous dissolution of both Houses – known as a double dissolution. If the conflict continues after such an election, the governor-general may convene a joint sitting of both Houses to consider the disputed legislation. This has occurred only once, after the election following the 1974 double dissolution. However, there are other occasions when the two houses meet as one: see Joint meetings of the Australian Parliament.
