Bavarian state election system

The Bavarian state election system (German: Bayerisches Landtagswahlsystem) is used to determine the currently at least 180 seats in the Landtag of Bavaria. The Bavarian Constitution (Article 14, Paragraph 1 of the Constitution) and the Bavarian State Election Law (LWG) provide for a so-called "improved proportional representation system." Unlike in federal elections, first and second votes are equally important for the proportional distribution of seats among the parties.
