Group voting tickets and the deals done by so-called "preference whisperer" Glenn Druery have come under scrutiny following two minor parties publicly turning against him during the election campaign.
WHAT IS A GROUP VOTING TICKET?
* The Victorian Electoral Commission (VEC) defines a group voting ticket as "a statement on how each party or group gives preferences to candidates".
* During a state election, voters can either number a group above the line and preferences are then decided by the party they vote for.
* Alternatively, they can vote below the line by listing preferences for five or more individual candidates and retain control over preferences.
HOW IS IT DIFFERENT IN VICTORIA FROM OTHER JURISDICTIONS?
* Victoria is the only jurisdiction which has a group voting ticket system in its Legislative Council, also known as the upper house.
* The system was abolished in NSW, South Australia and Western Australia after being used in the Australian Senate from the 1984 federal election until the 2013 federal election.
* Tasmania has never used ticket voting.
HOW ARE CANDIDATES ELECTED?
* For a candidate to be elected to the upper house, they must achieve a quota of votes (1/6 of the total number of votes + 1).
WHY IS GROUP TICKET VOTING IN THE NEWS?
* On Monday, The Guardian revealed the Animal Justice Party abruptly changed their preferences in the Victorian Upper House after months of negotiations with Glenn Druery.
* A Twitter war has since erupted between the Victorian Animal Justice Party and Mr Druery.
* On Wednesday night, the Herald Sun published a damning video leaked by the Angry Victorians Party which appears to show Mr Druery boasting about rorting Victoria's voting system.
