Electoral system of Germany
The German federal election system regulates the election of the members of the German Bundestag. According to the principles governing the law of elections set down in Art. 38 of German Basic Law, elections are general, direct, free, equal and secret. Furthermore, German Basic Law stipulates that normally Bundestag elections are to take place every four years and that one has a 'passive voting right' when one comes of age as well as an 'active voting right' as soon as one reaches the age of 18. All further stipulations for the federal elections are regulated by a law called the Federal Electoral Act. Elections are taking place on Sundays only; postal votes are possible by formal application.
Germans are electing their Members of Parliament with two votes in mixed-member proportional elections. One vote is for a direct candidate who is in a plurality voting system competition in every election district. The second vote (considered as more important) is for electoral lists for every state of Germany lined up and ordered by the parties to gain proportional representation. The Bundestag is then filled with candidates that won their electoral districts by first vote and candidates of the electoral lists according to share in second votes. Common practice is that direct candidates are also (well) placed on the electoral lists as a backup. As some memberships are assigned for compensation and overhang, fairness and rightfulness of the German election system is under steady discussion and development.

Principles Governing the Law of Elections
According to Article 38, §1 of the German constitution, “the delegates of the German Parliament (Bundestag) […] are elected in a general, direct, free, equal and secret vote.” These five principles of suffrage are fundamental rights: Their violation can be criticised in front of the Federal Constitutional Court of Germany by means of a constitutional complaint.
An election is general, if basically every citizen can take part in it: there are no restrictions such as in terms of income, sex, health or any other arbitrary distinctions. But according to the jurisdiction of the Federal Constitutional Court, the prescription of a minimum voting age is compatible with the commonalty of the election.
The exclusion from the active right to vote is also – within narrow limitations - consistent with the Basic Constitutional Law. The exclusion of the passive right to vote is governed by somewhat less strict regulations.
The right to vote is in principle reserved for German citizens and the so-called “status Germans” who are refugees and expelled persons of German descent that settled in Germany. The introduction of a right to vote for foreigners would require an alteration of §20 of the constitution.
An election is immediate, if the voter’s will determines the result directly. The process of an election based on lists compiled by the political parties however is compatible with the principle of an immediate election.
An election is considered free if the government does not obligate the people's voting decision in terms of content. According to the Federal Constitutional Court's dispensation of justice the principle of a free ballot would not be harmed if a compulsory vote was introduced by the Federal Electoral Law. The running of voting advertising at government expense would, though, be incompatible with this principle of electoral law. However, the Federal Government (made up of different political parties) is allowed to conduct public relations if its neutrality is strictly preserved.
Elections are confidential if the voter's decision is not known to anybody else. The German Parliament's voting law even states that no elector is allowed to announce his decision in the polling station. Postal voting is problematic because the secrecy of the ballot is not guaranteed; it has therefore to be taken as an exceptional case. Since the election's more important basic principle of universal suffrage would otherwise be violated, postal votes are admissible.
In principle an election is considered equal if all electoral votes have the same weight. This is for example not the case if constituencies differ considerably in size or if the way these constituencies are politically controlled causes advantages or disadvantages for certain groups of people(Gerrymandering).
For electoral lawmaking the most difficult part among the constitutional principles is the equality of the election. On the one hand, certain inequalities are unavoidable as the constituencies can not be of exactly equal size and the turnout, too, is not homogenous. On the other hand, the “Überhangsmandate” (the surplus of seats in Parliament a party gets due to gaining more constituency seats than it is actually allowed to have according to Parliament’s proportional seating contingent) and a “negatives Stimmgewicht” (negative vote value: an unwanted outcome changing an elector's vote to the opposite of their intended political will expressed with that vote) might influence the “one man, one vote” principle. On 3 July 2008, the Federal Constitutional Court declared the paradox of the “negatives Stimmgewicht”, which is still in effect, as unconstitutional in its decision. For this reason election law has to be changed by 30 June 2011 to the effect that a negative vote value will no longer be possible.
The five percent rule and the basic mandate clause are further strong interventions because they completely reject the influence of entire political streams and their voters in the parliament.
The five percent rule and the excess mandates (in German: Überhangmandate) are in principle approved by the Federal Constitutional Court and the German jurisprudence.
Right to vote
According to Art. 20, para. 2, p. 1 all power emanates from the people, that is the people of Germany. Therefore Art. 12 para. 1 of German Federal Electoral Law determines in accordance with constitutional law, that only Germans in the sense of Art. 116, para. 1 are eligible to vote.
Excluded from suffrage are Germans,
- who have been deprived of active suffrage by a court in connection with a conviction because of delicts within the fields of treason, compromise of the democratic constitutional state, threat to the external national security, criminal offence against constitutional bodies, as well as criminal offence at elections and ballots, as well as indictable offences against the national defence. (§§ 13 Nr. 1 BWahlG, 92a, 101, 108c, 109i, 45 Abs. 5 StGB)
- for whom had been ordered a custodian with contained field of activity through interlocutory injunction (§ 13 Nr. 2 BWahlG)
- who find themselves in an asylum according to §§ 63, 20 StGB after having committed an illegal action being criminally incapable because of an order from the criminal court
Eligibility to stand for election
Every German who has reached the age of majority, in Germany 18 years, is eligible to stand for election according to the German Basic Law (article 38, paragraph 2 BL). It has to be remarked that the age of majority can be altered by a simple federal law.
Eligibility to stand for election presupposes the right to vote. However, some German citizens do not have their permanent residence in Germany and in addition do not obtain the right to vote as a German citizen living abroad. They can still be elected if they meet all the other requirements. Yet, people can be deprived of their eligibility to stand for election in certain circumstances. This can happen in the case of an imprisonment of more than a year as is laid down in § 45, subparagraph 1 in the Strafgesetzbuch, the German criminal law.
Election Management Bodies
The most important election management body is the Federal Returning Officer, appointed by the Federal Ministry of the Interior. Responsibilities include running electoral procedures and chairing the election committee. The leader of the Federal Statistical Office usually holds this office. The Federal Returning Officer is assisted by the electoral committee and the Returning Officers of each Bundesland, the election supervisors and the electoral committee of each constituency as well as the election judges and the managing committee of each electoral ward. They are appointed by the federal government. The other members of the electoral committees are appointed by the Returning Officer.
Election management bodies (EMBs) are institutions of independent, societal self-organisation. In general they are considered to be a sort of federal agency. The Federal Ministry of the Interior, the Supreme Federal Authority, is responsible for the enactment of certain regulations necessary for federal election procedures. However, the Federal Ministry of the Interior does not have the authority to issue directives against the election management bodies.
Scrutiny of Elections
Within two months after the federal election (German: Bundestagswahl) any voter can request the scrutiny of elections. According to the established practice of the Federal Constitutional Court (German: Bundesverfassungsgericht) the Committee for the Scrutiny of Elections of the Bundestag, the parliament of Germany, has to reject a request if the distribution of mandates did not change even with the request being granted. The Committee for the Scrutiny of Elections only makes sure that the Federal Voting Act is implemented properly; it does not deal with possible unconstitutionalities.
If the Bundestag rejects the veto, an appeal to scrutiny of elections can be lodged to the Federal Constitutional Court of Germany within another two months. This appeal has to be joined by 100 eligible voters.
If the veto is successful, the affected member will lose his or her seat in parliament. This member can in turn file a lawsuit against the adjudication.
No appeal to scrutiny of elections against decisions made by the German Bundestag has thus far been successful.
Appointment of candidates
The parties' right to propose candidates
Only parties that have been represented in the Bundestag or a Landtag by at least five delegates since the last election are entitled to propose their own candidates. Other parties have to announce their candidature to the Federal Returning Officer in time, i.e. not later than 90 days before the election day of periodic elections of the Bundestag. They must have been accepted as a party by the Federal Electoral Committee beforehand.
Proposal of candidates for constituencies
The applicants from a party must be elected in a democratic and secret election by an assembly of the party members in a constituency or by a similar board appointed by the party. Every party member entitled to vote is allowed to propose candidates. A candidate does not have to be a member of the party. Since the 2009 German Bundestag elections no member of a different party may be nominated. A written record of the election must be presented to the District Returning Officer, who is responsible for checking the proposal. He points out possible deficiencies and allows remedies to be made.
A county election nomination is only accepted if the nominee belongs to a party that is represented in the Bundestag or the Landtag, or if the party represents a national minority. Otherwise the nominee must have at least 200 signatures from eligible voters in the constituency. It does not make a difference whether the suggestion is handed in by a party or not. Hence a candidate does not need to be supported by a party in a constituency if he has sufficient signatures. The county election nominee must also nominate a person of trust and a proxy who are allowed to release statements to the leader of the county election.
A county election nomination can be recalled either by a joint statement from the two persons of trust or by a statement from the majority of the signataries of the nominee. Through a declaration from the two persons of trust the name of the suggested person can be changed in case the originally suggested person loses his eligibility or dies. Once the nomination is authorised it can neither be recalled nor changed.
If a candidate with a direct mandate dies before election day, the election is cancelled in this constituency. Within the next six weeks, the election is held again, allowing the deceased candidate's party to appoint a substitute candidate. This by-election follows the same rules as the main election. This means that Germans who have come of age in the time between the main and the by-election are not allowed to vote.
Regional lists of parliamentary candidates for election to Federal Parliament
According to the Federal Election Law the nominations for the regional lists basically result in the same way as the constituency nominations. In addition, the order of the regional list is determined by secret election.
The regional list of a party which is neither represented in the Federal Parliament nor in a State Parliament and which does not represent a national minority, requires for its admission the signing of at least a thousandth of the state's eligible voters, however not exceeding 2,000 signatures. For the nomination of confidants and the modification of the regional list, the regulations concerning the constituency nominations are applied correspondingly.
For the calculation of the election threshold, the candidate lists on state level of one party are generally treated as connected, unless the confidants issue a differing declaration to the Federal Returning Officer.
The voter has two votes. The Federal Election System distinguishes between 'First' and 'Second' vote. However, these terms do neither refer to a hierarchical order (of importance) of the votes, nor do they refer to a logical (chronological) sequence in a valid election process. According to public polls, about 70% (2002) to 63% (2005) of the voters mistakenly thought the first vote to be more important than the second. In some State Election Systems that have two voting systems which are 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.
The first vote allows the elector to vote for a direct candidate of his constituency, who applies for a direct mandate in the Bundestag (see illustration above, no. 2). Relative majority voting is used, which means that the candidate who receives most of the votes gets the mandate. If the vote results in a tie, the lot drawn by the leader of the regional election is deciding. 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 is 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 less 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.
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 who have achieved at least 5 percent of valid second votes (see election threshold). Since 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 (see illustration above, no.4). Discrepancies result from excess mandates and the election 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 election 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 the respective 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 confidiality 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 amount 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.
Seats in the German Bundestag distributed by regional lists are only given to parties surpassing a five percent election threshold of the federally valid second votes. Alternatively, if a party wins at least three constituencies, a party still gains seats by proportional representation according to the number of second votes they received. Those second votes for parties that meet neither requirement will not be taken into account for the distribution of seats among the rest of the parties. The three-constituency rule favours those smaller parties with a regional stronghold. For example the German Party, which gained 15 seats in the 1953 elections with only 3.3% of the second votes and ten constituencies. In 1957, they gained 17 seats in the German Bundestag with 3.4% of the second votes and six constituencies.
In 1994, a party benefited from the basic mandate clause which had not been enacted since the 1957 election. 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 percent of the second votes. They only had the status of a political group, rather than a parliamentary party. In order to have the particular powers pertaining to this important political status, they would have had to exceed the election threshold.
The clause is meant to minimise the risk of party fragmentation, which partially caused the incapacitation of the parliament 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, which states that 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 overall for the 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 it is allowed to violate a constitutional principle within certain limits, if this is essential to achieve a more important constitutional objective such as the adherence to a principle of electoral law. Because of this, the Federal Constitutional Court allows the threshold clause to be maximally five percent. Thus the legislator has no possibility of increasing it.
National minority parties, such as the SSW, which last ran for parliamentary election in 1961, are now freed from the election threshold due to the fact that under Constitutional Law it is imperative that minorities are protected. 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 is taken 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 (not 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 excess mandates. Consequently the Bundestag becomes larger by the amount of additionally gained seats. The other parties do not receive compensatory mandates. Following the election in 1998 there were 13 excess mandates, 5 excess mandates in 2002 and 16 excess mandates in 2005. In theory it is possible to gain 299 excess mandates. This would occur if all 299 direct mandates are gained by parties who do not receive enough second votes to gain proportional mandates.
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.
Classification and assessment of the system
The Bundestag, Germany’s parliament, is elected according to the principle of proportional representation. In some cases, this system is also referred to as mixed member proportional representation. This, however, is incorrect considering the fact that the mandates gained directly in each federal state are compared to the number of second vote mandates and any differences are compensated with candidates from the party’s list at the state level, if, according to the principle of proportional representation, a party gains more second vote mandates than direct mandates. Therefore, it is more accurate to call it additional member system. However, the so-called mixing election system can be described as parallel voting whereas a certain number of representatives is elected through one of the systems and the other independent representatives are elected through the other system without any mandates being taken over by both of the systems. [clarification needed]
Voting the Bundestag is complicated; especially the importance of the second vote is sometimes underestimated. However, the voting system combines many of the advantages of both the plurality and the proportional voting system. Time has proven that this voting system mainly allows for a proportional distribution of seats, stable governments, change of governments, the possibility of new parties joining the parliament, and in comparison to the Reichstag, the precursor parliament of the Bundestag in the Weimar Republic, it allows for a parliament capable of acting. Presently, the big parties are not considering any introduction of the majority voting system like they did at the beginning of the first great coalition in 1966.
However, major criticism has been brought up with regard to the Federal Election System. The overhang seats are problematic in the sense that they distort the proportional representation (resulting from the second votes). The Federal Constitutional Court of Germany argues that this distinctive feature is compatible with the legislator’s will of ensuring a regionally balanced composition of the Bundestag. Nevertheless, the paradoxical possibility that a party may receive more seats in the Bundestag by receiving fewer second votes in certain states or vice versa is a consequence of the overhang seats. On July 3, 2008, the Federal Constitutional Court declared the possibility of negative vote weight as unconstitutional. It has ordered the legislative to revise the Federal Electoral Act until June 30, 2011 to the effect that a negative vote value will no longer be possible.
Discussions about the implementation of a majority voting system
By the end of 1955 the CDU/CSU (political union of the parties of the Christian Democratic Union and the Christian Social Union) together with the German party (in German: Deutsche Partei (DP)) brought forward a first draft outlining a possible majority voting system. According to this draft 60 percent of the mandates were supposed to be determined by majority votes and only 40 percent according to proportional representation. Adenauer’s attempt to end the CDU/CSU’s dependence on the FDP (the Liberal Democratic Party) as well as to limit the SPD’s (the Social Democratic Party) prospects of getting elected was unsuccessful.
When the first Grand Coalition (1966–1969) took office, there were strong tendencies within both major parties, CDU and SPD, to abandon proportional representation which had existed/had been applied since the foundation of the German Federal Republic in 1949. Instead, they suggested implementing the majority vote system. These plans were even part of the coalition agreement. The smaller FDP which has no chance of winning the majority in an election district, protested because the implementation of this voting system would have threatened its further existence. Ultimately, however, the introduction of the majority vote system failed because large parts of the SPD were convinced that it would not have meant better prospects of power. Paul Lücke (CDU), Federal Minister of the Interior, resigned from office on April 2, 1968. Since then there have been no more attempts to introduce the majority vote system in Germany.
The paradoxes which occur with the largest remainder method are avoided by the recent introduction of the Sainte-Laguë method. The difficulty of negative vote weight however still continues to persist at first. But according to a verdict given by the Federal Constitutional Court of Germany on July 3, 2008, the Federal Election Law (“Bundeswahlgesetz”) will have to be changed until June 30, 2011 so as not to allow for a negative vote weight any more in the future.
Election of the first German Bundestag (14 August 1949) – The election system which was valid for the election of the Bundestag in 1949 has been changed significantly in the following decades. Because the Parliamentary Council couldn't agree on a written formulation of the voting system in the Grundgesetz, the Federal Election Law was ratified by the heads of government of the German states. The right to vote was granted from the age of 21, the right to be elected from the age of 25.
The constitutional number of representatives counted 400, plus possible overhang seats and 19 Berlin representatives. The federal territory was divided into 242 electoral districts, each one having one direct candidate being elected according to the relative majority voting, which is still valid. As a result of two CDU overhang seats, the Bundestag of 1949 consisted of 402 representatives.
Each German state formed its own electoral district. Consequently, the number of representatives of a state was determined in advance (excluding overhang seats).Accordingly, the five-percent hurdle and the Grundmandat-clause (one direct mandate was sufficient to join the Bundestag) were valid merely in the federal states.
A single-vote system was used. Using this single vote, the voter elected both a state party list and a direct candidate of the same party from his electoral district. Therefore the voter did not have the possibility to give separate, independent votes for the person or the direct candidate and the party or the list. The voter of an independent direct candidate had in comparison with the two-vote system of today not the possibility to vote a party, with the risk that his vote in a case of unsuccessfulness of the candidate was lost.
In case a direct candidate resigned from the Bundestag, the corresponding electoral district had to hold a reelection. This happened fourteen times the first being the Kulmbach by-election, 1950.
The proportional mandates (Proporzmandate) were allocated using the D'Hondt method which disadvantages small parties. These parties were further disadvantaged because the seats were allocated on a per state basis.
Election of the 2nd German Bundestag (September 6, 1953) – In 1953 for the first time, a law (Bundeswahlgesetz) designed by the German Bundestag was the basis for the federal elections. This law contained some mayor alterations compared to the former election law:
The dual-vote system with the respective possibility of vote splitting was introduced. In order to overcome the election threshold, the party needed to receive a minimum of 5% of all second votes. Although the election threshold was overruled for parties of national minorities, the Südschleswigsche Landesverband (SSW) was not able to re-enter into Parliament. The number of proportional seats increased from 400 to 484, while the 242 electoral districts were maintained. Consequently, the Bundestag is equally represented by seats voted directly as well as via second vote, disregarding additional second vote mandates that have resulted from overhang seats. The number of Berlin's parliament members increased from 19 to 22. In the case of a direct candidate withdrawing from the Bundestag, a new election in his voting district was no longer necessary. Instead, the candidate being next in the state's list of candidates ("Landesliste“) would substitute the candidate.
Election of the 3rd Bundestag (September 5, 1957) – Today's electoral law is basically the same as it used to be in 1957. The two-stage distribution of seats connected with states' canditates lists was introduced, which brought along the problem of negative vote weight. At the same time, the disadvantage of smaller parties was clearly reduced with the D'Hondt method. The Grundmandatsklausel, which says that a party needs at least 5% of the second votes to get any seat in the Bundestag, was modified: from now on at least three direct mandates were needed to overcome this clause. Since the Saarland joined the Federal Republic of Germany on January 1, 1950, five electoral districts were added to the 242 already existing districts and the number of the mandates distributed by proportion was raised from 484 to 494. The absentee ballot was introduced as well.
Election of the 5th Bundestag (September 19, 1965) The electoral districts were rearranged, the number was increased from 247 to 248. Accordingly, the number of mandates distributed by proportion was raised from 494 to 496.
Election of the 7th Bundestag (November 19, 1972) By changing article 38 (2) of the Basic Law in 1970 the voting age was lowered from 21 to 18 and the legal age to be eligible for election was adapted to the voting age, which was 21 at that time. Before that, one had to be 25 to stand for election.
Election of the 8th German Bundestag (October 3, 1976) When the change of sec. 2 BGB (German Civil Code) came into effect on January 1, 1975, the age of consent was lowered from 21 to 18 years. This means that since the election of 1976 citizens have the right to vote and to run for office at the age of 18.
Election of the 11th German Bundestag (January 25, 1987) Since the German federal election in 1987, the largest remainder method, which is neutral towards the size of the parties, has been applied instead of the D'Hondt method. The discrimination of/against small parties when distributing mandates (Proporzmandate) could hereby be completely abolished. Because of paradoxes that occur in the largest remainder method, the danger of negative vote weight expanded to all federal states, even to those without overhang seats. The voting right for Germans living abroad was introduced during this election.
Election of the 12th German Bundestag ( December 2, 1990) Briefly before the Bundestagswahl of 1990, the Federal Constitutional Court decided that the situation of the recently reunited Germany showed a special case. An election threshold for the entire election district was unconstitutional. For this reason, a party had to receive at least 5% of the second votes either in the old federal territory including West-Berlin or in the new federal territory in order to win seat in the German Bundestag (Lower House of German Parliament). This special regulation was only valid for the elections in 1990.
In the federal states that were formerly part of Eastern Germany, including Berlin, 80 constituencies were added. Because of this, the number of constituencies increased to 328, the number of proportional mandates to 656. Another consequence of German reunification was the abolition of a special regulation for West Berlin. This regulation prescribed that the Berlin City Parliament elected 22 representatives into the Bundestag on the day of the federal election.
Election of the 15th German Bundestag (22 September 2002) – For the election of the Bundestag in 2002, the number of constituencies was reduced from 328 to 299, as was the number of proportional mandates (from 656 to 598).
Election of the 17th German Bundestag (27 September 2009) – For the 2009 election of the Bundestag, the Hare-Niemeyer method was substituted by the Sainte-Laguë/Schepers method. For the first time, parties could no longer nominate candidates who were members of other parties. The circle of Germans living abroad who are entitled to vote was extended.
