Q: What happens if neither side make an agreement with the cross benches?In these circumstances, Ms Gillard can continue on as Prime Minister. It would be up to the Opposition to defeat the government in Parliament if it wanted a change of government or to force an early election.
If the Gillard government was constantly defeated on the floor of parliament but the Opposition was not in a position to form government, then the House could be viewed as unworkable. Independent Tony Windsor has talked of needing a new election if no agreement for government can be reached. However, to get an early election, Mr Windsor and his cross bench colleagues would have to engage in deliberate tactics to make the House unworkable.
Q: Would we have an early election if the government fell after a few months?Not necessarily. If the Gillard government continued on for a few months and lost the support of the cross-benchers, or lost a seat at a by-election, the Prime Minister could request an early election. However, if an alternative government could be formed in the existing House of Representatives, the Governor-General may decline a request for an early election and appoint a new prime minister.
This happened in 1941. The Menzies Coalition government was re-elected in September 1940. It lost its majority but continued in government with the support of cross bench independents. Menzies was replaced as prime minister by Country Party leader Artie Fadden in August 1941. In October 1941 Fadden's government was defeated by the classic no-confidence motion of varying the appropriation bill by one pound. The independents backed Labor's motion and John Curtin became the new prime minister.
The most recent example of a mid-term change of government took place in Queensland in 1996 when the Goss Labor government lost its majority at a by-election in the Townsville seat of Mundingburra. Goss resigned and the Coalition was sworn into office under new premier Rob Borbidge.
Q: Would there be another Senate election?No. The Constitution does not explicitly state that another half-Senate election cannot be held, but it is implicit in the fixed term of the Senate that the Senators elected last weekend must take their seats in July next year. There cannot be another half-Senate election until after July 2013.
I would also think it is implicit in the Constitution that a double dissolution could not be engineered before July next year. Any deadlock between a government and the Senate should be with the new Senate after July next year, not before.
Anyway, the deadlocked chamber is the House, not the Senate. Any early election will be a House only election, with all the normal election procedures including 33 minimum campaign period.
The last separate House election was in December 1972 when the Whitlam government was elected. Senate and House election had been out of step through the 1960s and a Senate election was not due at the end of 1972.
Q: Could any agreement with the independents fix the term of Parliament.Yes. The current term could be fixed simply by passing legislation fixing the date of the next House election. The dates of future elections could also be fixed. However, none of these dates could be constitutionally entrenched without a referendum. Legislation fixing an election date could be passed, but it could equally be removed by the passage of repealing legislation.
