The prime minister’s audacious use of an obscure and rarely used provision in the constitution that allows the governor general to recall both houses of parliament caught his political opponents by surprise. If the doible dissolution will happen, Australians were due to go to the polls before the end of the year. A double dissolution, last used in 1987, is a mechanism designed to break deadlocks. It can occur when a bill is repeatedly blocked in the Senate. In a double dissolution election, all seats are up for grabs. Australia’s complex system of voter preference distribution previously allowed micro parties to secure Senate seats, even if they receive a very small percentage of the primary vote.
