In elections for the National Council (Nationalrat), which is the lower house of Austria’s parliament, proportionality is maximized through the utilization of a three-stage process of allocating mandates; in state and local elections a similar method is used, but it is simpler: it only involves two stages. There are also some minor differences among states because each state has its own election law for state and local elections, whereas the National Council elections are governed by a specific federal election act (Nationalrats-Wahlordnung 1992). Presidential elections and European Parliament elections are also governed by federal law.
