for the election of the
16th Bundestag. The voter has two votes. The federal election system distinguishes between 'first' and 'second' votes. However, these terms refer neither to a hierarchical order of importance of the votes, nor to a logical (chronological) sequence in a valid election process. According to public polls, between 63% (2005) and 70% (2002) of voters mistakenly thought the first vote to be more important than the second. In some state election systems that have two voting systems modelled after the federal election setup, the votes are called 'vote for person' and 'vote for list'. It is important that both votes have distinct functions.
First vote The first vote allows the elector to vote for a
direct candidate of their
constituency, who applies for a direct mandate in the Bundestag (see illustration above, no. 2). A
plurality voting system is used, which means that the candidate who receives more votes than any other candidate gets the mandate. If the vote results in a tie, the lot drawn by the leader of the regional election is decisive. In this case, the votes for the other candidates are invalid. The primary function of the first vote is to personalize the election. As there are 299 constituencies at the moment, the same number of mandates in the Bundestag are distributed to the elected candidates in each district. However, the first vote does not determine the power of the parties in the Bundestag. For each direct mandate in a Bundesland the party always receives one mandate fewer from the second vote. The size and the geographical shape of the electoral constituencies are revised by an electoral committee appointed by Germany's Head of State. The final decision is made by the German Bundestag and can be found in an attachment to the federal electoral law.
Second vote For the distribution of seats in the German Bundestag, the second vote is more important than the first vote. This second vote allows the elector to vote for a party whose candidates are put together on the regional electoral list. Based on the proportion of second votes, the 598 mandates are distributed to the parties which have achieved at least 5 percent of valid second votes (i.e. reached the
electoral threshold). Following the 1987 German Bundestag elections, the distribution of seats was made according to the
Hare-Niemeyer method. Due to a change in the law passed in January 2008, the distribution of seats is now made according to the
Sainte-Laguë/Schepers method. The proportion of seats a party gets in the
Bundestag approximately equates to the percentage of votes the party gets in the election. Discrepancies result from overhang and the electoral threshold. According to §6, para. 1, clause 2 of the
Federal Election Law the electors' second votes are not accounted for if those electors give their first votes to a successful and autonomous direct candidate (a candidate who is not nominated by a party). This rule is designed to prevent a double influence on the composition of the
Bundestag. A similar problem occurred at the
federal election in 2002. The
PDS got two
direct mandates in
Berlin, but with only 4.0% of second votes they failed to pass the electoral threshold. The second votes from the electors who voted for those direct candidates counted nevertheless, since in this case both candidates belonged to a party which had handed in a regional list in that
Bundesland. In its decision of November 23, 1988 (
Federal Constitutional Law 79, 161), the
Federal Constitutional Court pointed out the relevant loophole in the
Federal Election Law to the
legislative body. Abolishing the system with first and second votes with the possibility of splitting votes – meaning the elector's option to vote for a
direct candidate and for a party independently – would solve the problem automatically.
Abstention and spoilt votes German parliamentary election law does not have explicit abstention; a ballot paper without markings on it is considered a spoilt vote (separated into first and second vote). Furthermore, votes are spoilt if the voter's intention cannot be recognised without doubt, if the ballot paper contains additions or conditions or if it is not an official document. Since the general elections in 2009, only the first vote is spoilt on ballot papers designed for a different constituency as long as they contain the correct regional list for the second vote. The law of the German federal election does not consider ballot papers which are marked in a way that endangers the confidentiality of the ballot (as, for example, votes marked with an upright cross) as spoilt. There are further reasons for invalidity concerning the postal vote: Both votes are invalidated if the envelope for the postal vote is empty, if it contains several differently marked ballot papers or if it actually should have been rejected (including also those ballot paper envelopes which differ from the rest in a way that endangers the election secrecy.) In contrast, the votes of voters who die or lose their right to vote before the ballot vote takes place explicitly remain valid. Invalid votes, equally to non posted votes, have no effect on the result of the poll. Nevertheless, their number is officially counted and published. According to § 4 of the election statistics act, the cause of invalidity is also a census criterion to be mentioned in the official election statistics. The numbers for a total of twelve categories of (partly) invalid ballot papers have been published at last (for the Federal Parliament elections in 2005). However, it only concerns combinations of the three basic categories "empty or crossed out", "multiple crosses" and "other causes", divided into first and second votes. Thus one can hardly deduce the reason for the invalidity; whether it was a matter of purpose, mistake or just ignorance of the voting right. For combinations of invalid and valid votes on a ballot paper, the belonging elected (major) parties have been deciphered as well. Invalid votes count as non votes in the financing of the parties. The parties do not receive any money for them. As the party's financing is capped and the total sum is regularly being utilised, the discrepancy of valid votes for parties who take part in financing is practically low. A small number of invalid votes is generally beneficial for parties with above average fund raising (membership fees included) seeing that more money remains in the bonus fund.
Electoral threshold Seats in the German Bundestag are allocated to regional lists of parties that either pass a five percent
electoral threshold of the federally valid second votes or win at least three constituencies. The distribution of seats does not take into account second votes for parties that meet neither requirement. Parties qualifying for proportional representation in this manner are recognized as party groups, as a party must win at least five percent of the vote to qualify as a full parliamentary party, or
Fraktion. Those too small to form a fraktion can make a
Gruppe instead. The three-constituency rule favours smaller parties with a regional stronghold. For example, the
German Party (DP) only won 3.3% of the second vote in 1953, but was able to win 15 seats by electing ten members from constituency seats, mostly in the party's heartland of
Lower Saxony. In 1957, the DP won 3.4% of the second vote but elected six members from constituency seats, enabling them to send 17 members to the Bundestag. The three-constituency rule was not used again until 1994, when the
PDS won four
direct mandates in Berlin, enabling them to send 30 delegates to the Bundestag, despite the fact that they had only 4.4% of the second vote. It was used in the
2021 election, in which PDS's successor,
Die Linke, won exactly three constituencies (
Berlin-Treptow-Köpenick,
Berlin-Lichtenberg, and
Leipzig II), earning it 39 seats on 4.9% of the second vote. This clause is meant to minimise the risk of party fragmentation, which contributed to the incapacitation of the
Reichstag in the
Weimar Republic. The clause is not explicitly mentioned in the constitution, as this could cause a conflict with the fundamental principle of equal votes (each vote must have equal weight). However, the general consensus is that the clause is important for the stability of the party system, the capacity of the parliament and the government, and the overall political stability of the state. Thus, a balance must be achieved between the two existing constitutional objectives. The
Federal Constitutional Court approves of the threshold clause, arguing that violation of a constitutional principle (within certain limits) must be permitted if it is essential to achieve a more important constitutional objective. Therefore, the Federal Constitutional Court allows the threshold clause to be up to five percent. Thus, the legislature has no possibility of increasing it. National minority parties, such as the
SSW, which won a seat in the
2021 and
2025 parliamentary elections, are now freed from the electoral threshold under the constitutional imperative to protect minorities. This special regulation however does not necessarily apply to a Turkish party, as the Turkish do not yet enjoy the status of a national minority in Germany, unlike the Danish party in Schleswig-Holstein, the SSW, or the
Sorbs in Saxony.
Distribution of seats At first, the number of successful independent direct candidates and the successful direct candidates whose party did not make it into the German Bundestag are subtracted from the total number of 598 mandates. In the
parliamentary election of 2002, both direct candidates were members of the PDS party. Only in the
parliamentary election of 1949 were there successful independent direct candidates. The remaining proportional mandates (596 seats in the election of 2002 and all of the 598 seats in 2005) are distributed among the parties which have obtained at least five per cent, or three
direct mandates according to the results of all second votes, in the
Sainte-Laguë/Schepers procedure (before the federal election in 2009 it was the
Hare-Niemeyer procedure). Afterwards, the obtained proportional mandates of each party are distributed among the candidates' lists of the Bundesländer, according to the number of their second votes in the respective Bundesländer, by following the same procedure. The outcome of this procedure shows how many proportional mandates each party has gained in each Bundesland. The candidates who have achieved a seat in the Bundestag can then be identified. At first, the victorious direct candidates of a party obtain their mandates in a Bundesland. Within the Bundesländer, in which the number of achieved direct mandates of one party is smaller than the number of achieved proportional mandates, the difference is settled by list mandates i.e. candidates of the Bundesländer list in order of appearance, whereas candidates who have already gained a direct mandate in their district (no matter which Bundesland) are simply left out. If a party in a
Bundesland receives more
direct mandates than proportional mandates, all the successful candidates in constituencies gain additional seats in the Bundestag. These seats are called
overhang seats. Consequently, the Bundestag becomes larger by the number of additionally gained seats. Starting with the 2013 election, other parties receive
leveling seats. In recent years, the number of overhang seats was 13 in 1998, 5 in 2002, 16 in 2005, 24 in 2009 and 33 in 2013. In 2017, after the formula was adjusted somewhat, there were 111 overhang and levelling seats. In theory, there is no limit to the possible number of overhang seats; this is because one or more parties could win constituency seats while having arbitrarily few list votes. If a delegate of the Bundestag who was elected in a constituency in which his or her political party gained a number of excess mandates resigns, his or her seat remains free and cannot be used by the following candidate on the party's list. At the beginning of the 2002
legislative period the Bundestag consisted of 603 delegates. When
SPD delegate
Anke Hartnagel died and the head of SPD in
Thuringia,
Christoph Matschie, resigned, this regulation was enacted. As a consequence, the 15th Bundestag consisted of 601 members. Debate over the awarding of overhang and leveling seats was renewed after the
2021 German federal election produced a Bundestag with 736 members, which made it the largest freely elected parliament in the world. The
Scholz cabinet introduced a 2023 reform law to fix the size of the Bundestag at 630 members, which would be achieved by eliminating all overhang and leveling seats, as well as the
Grundmandatsklausel which awards full proportional representation to parties winning at least three constituency seats, even if the five-percent threshold is not met. Instead, a party's total number of seats would be determined strictly by its share of
Zweitstimmen (party votes), and the five-percent threshold is absolute. If a party wins overhang seats, the seat winners with the fewest votes would not enter the Bundestag. Parties representing minority groups are still exempt from the five-percent threshold. The law is subject to constitutional challenges by the CSU and The Left, both of whom benefit from the previous system, though President
Frank-Walter Steinmeier signed the law after personally determining he believed it was constitutional. == Classification and assessment of the system ==
