Prior to amendments made in 2014, the Burgenland constitution mandated that cabinet positions in the state government (state councillors, German: Landesräten) be allocated between parties proportionally in accordance with the share of votes won by each; this is known as Proporz. As such, the government was a perpetual coalition of all parties that qualified for at least one state councillor.[1]
In the 2005 election, the SPÖ won an absolute majority with 52.2% of votes.
For parties to receive any representation in the Landtag, they must either win at least one seat in a constituency directly, or clear a 4 percent state-wide electoral threshold. Seats are distributed in constituencies according to the Hare quota, with any remaining seats allocated using the D'Hondt method at the state level, to ensure overall proportionality between a party's vote share and its share of seats.[2]
In addition to voting for a political party, voters may cast preferential votes for specific candidates of that party, but are not required to do so. These additional votes do not affect the proportional allocation based on the vote for the party or list, but can change the rank order of candidates on a party's lists at the state and constituency level. Voters may cast one preferential vote at the state level, or three at the constituency level. A voter may not cross party-lines to cast a preference vote for a candidate of another party; such preference votes are invalid.[2]
