2010 Styrian state election

Prior to amendments made in 2011, the Styrian 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.

The 2005 election brought significant changes in Styrian politics. The SPÖ won a narrow victory over the ÖVP, becoming the largest party in the Landtag for the first time since 1953; Franz Voves became the first SPÖ governor of Styria. The FPÖ also lost all its seats for the first time ever. The KPÖ returned to the Landtag after a 35-year absence, placing third with 6.3% of votes and four seats, on the back of a popular campaign and recent success in Graz. After the election, the SPÖ had five state councillors and the ÖVP four.

The 56 seats of the Landtag of Styria were elected via open list proportional representation in a two-step process. 48 of the seats were distributed between four multi-member constituencies. For parties to receive any representation in the Landtag, they must win at least one seat in a constituency directly. Seats were distributed in constituencies according to the Hare quota, with eight leveling 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 the parties already represented in the Landtag, four parties collected enough signatures to be placed on the ballot:

• Freedom Party of Austria (FPÖ)
• Alliance for the Future of Austria (BZÖ)
• Christian Party of Austria (CPÖ)
• Party for the Environment, People and Labour (PUMA)
