Electoral system The 128 members of the National Council were elected in 47 single- and multi-member constituencies; there was one seat for every 20,000 citizens, with seats allocated to cantons in proportion to their population.Dieter Nohlen & Philip Stöver (2010) Elections in Europe: A data handbook, p1886 The elections were held using a three-round system; candidates had to receive a majority in the first or second round to be elected; if it went to a third round, only a plurality was required. Voters could cast as many votes as there were seats in their constituency. In six cantons (Appenzell Innerrhoden, Appenzell Ausserrhoden, Glarus, Nidwalden, Obwalden and Uri), National Council members were elected by the Landsgemeinde.
