The Electoral System
The Parliament of the Federal Republic of Germany (FRG) consists of a lower house, the Bundestag, whose members are directly elected by universal adult suffrage, and an upper house, the Bundesrat, composed of representatives appointed by the Lander. The two bodies are not coequal chambers, with the Bundestag being the more powerful of the two.
The Bundestag is composed of 598 members elected for a four-year term of office. …
The composition of the Bundestag is determined by the Mixed Member Proportional (MMP) system – also known as personalized proportional representation – which combines elements of the single-member constituency plurality system with PR. Under this system, the country is divided into a number of single-member constituencies (Wahlkreisen) equal to half the total amount of seats in the Bundestag. There were 248 of these constituencies between 1957 and 1987, 328 between 1990 and 1998, and 299 since 2002. These constituencies are allocated among the Lander in proportion to the size of their populations, and seats are filled by the plurality or first-past-the-post method, under which the candidate obtaining the largest number of votes in each constituency is elected.
However, in addition to nominating individual candidates for the direct mandate (Direktmandate) elections at the constituency level, political parties set up lists of individuals at the Land level (Landesliste). Each German casts two votes, namely a first vote (Erststimme) for a constituency candidate, and a second vote (Zweitstimme) for a party list. Party lists are closed, so electors may not choose individual candidates in or alter the order of such lists. Of the two votes, the second vote is the most important, since it is the one that determines the composition of the Bundestag.
In order to participate in the proportional allocation of Bundestag seats, a party must receive at least five percent of all valid second votes cast; however, this requirement is waived if a party wins three or more constituency seats. …
…in 2013 Parliament passed a new electoral reform which introduces additional adjustment seats (Ausgleichsmandate) to achieve a fully proportional allocation of Bundestag mandates among qualifying parties, thus neutralizing any disparities resulting from the allocation of overhang seats.
Under the reformed system, all 598 Bundestag seats are allocated among the Lander in proportion to the size of their German population. Then, a non-binding allocation of seats among qualifying parties is carried out in each Land by the Sainte-Lague/Schepers method of PR; if a party wins more constituency seats in the first vote of a particular Land than the number of seats it would be entitled to according to the result of the second vote, it keeps the overhang seats. The nationwide seat total obtained by each qualifying party after adding up the results from all sixteen Lander is the minimum number of mandates the party is entitled to receive, and the size of the Bundestag is adjusted accordingly, so that each qualifying party secures at least its corresponding minimum seat total, but in a way such that the distribution of seats equals the nationwide allocation of mandates in the expanded Bundestag by the Sainte-Lague/Schepers method.
From this point forward, the system generally operates in the same way as before: the mandates obtained by each party are allocated at the Land level in proportion to the number of votes received by their Land lists; the direct mandates won by a party at the constituency level of a particular Land are then subtracted from the total number of seats allocated to that party’s list; and the remaining seats are filled by the candidates on the Land list in the order determined before the election. Nonetheless, if a party wins more constituency seats in the first vote of a particular Land than the number of seats it would be entitled to according to the result of the second vote, the distribution of seats among the party’s Land lists is adjusted so that each list is allocated at least its corresponding number of constituency seats, without changing the party’s nationwide seat total.
