Overlapping candidacy system

Overlapping candidacy systemWhat is (Choufu Kurikko Hoseido)?House of Representatives general electionAdopted inelectionAn election system that allows you to run for the same time.


Public office election lawArticle 87 prohibits duplicate candidacy in two different public office elections at the same time.

However,1994 Due to the revision of the law, the election of members of the House of RepresentativesProportional representationin the case of,Small districtIt is stipulated that you can run for the same time asPublic office election lawArticle 86-2, Paragraph 4), belonging when runningPolitical partyWith the permission of, candidates can run for both "single-seat constituency elections" and "proportional representation elections."However,Public office election lawupperPolitical party requirementsIf you run for "other political organizations" that do not meet the above requirements, you cannot duplicate.

A list of proportional representations allows political parties to rank multiple duplicate candidates in the same order.In this case, the ratio of the number of votes of the losing candidate to the number of votes of the winner in the single-seat constituency (Loss rate), And the ranking of the proportional list is decided from the candidates with the highest defeat rate.

Duplicate candidates are in proportional districts even if they lose in single-seat constituenciesResurrection winningTherefore, there is a phenomenon that there are multiple members based on a single single-seat constituency to which one seat is assigned, depending on the district.In the election system, the single-seat constituency system in which votes are held at the same time and the proportional representation system are equal systems that stand side by side and are in a mutually complementary relationship.Therefore, the expression "proportional revival" that is originally the result of the single-seat constituency system is inappropriate, but as mentioned above, the result of the single-seat constituency may affect it, and the proportional representation system is effectively subordinate. It has become.In addition, the word "proportional revival", which is widely used by the mass media, has strengthened this impression.Therefore, candidates who have "revived" will be labeled as "winning even though they lost in the single-seat constituency" even after winning.

Movement of each political party

Duplicate candidacy under the parallel system of proportional representatives of the House of RepresentativesHouse of Councillors electionIn addition, each political party has a slightly different policy for duplicate candidacy, which is prohibited in the election of public officials.


LDPIn the case, duplicate candidacy is basic, but every time people run for single-seat constituencies only (73 years old only in proportional districts)Retirement ageCandidates aged 73 and over who are forced to run only in single-seat constituencies due to the system, and single-seat constituencies that appeal to cut off the retreat of the revival election such as the president class).It is natural to list duplicate candidates with a higher "list" ranking than other duplicate candidates in order to expand the support votes, and the candidates and parties who have moved the constituency from the original ground are emphasized Candidates who ran for the constituency that was positioned as the constituency (1996 OfSuzuki Muneo-Ryuji Fukaya-Shinichi Eto,2000 OfTadao Iwasaki-Hiroshi,2003 OfKunio Hatoyama-Tokuichiro Tamazawa-Koichi Hirata-Tatsuya Ito・ Iwasaki,2005 OfMasatada Tsuchiya-Satsuki Katayama-Yukari Sato-Abe Toshiko-Makiko Fujino-Tomomi Inada-Kyoko Nishikawa-Sanae Takaichi・ Tamazawa, etc.) are ranked high in the list.

There is also an aspect of taking a step back without fighting. There is, and it is necessary to think carefully. "Masayoshi YoshinoBecame two people). From the 2 House of Representatives election, all duplicate candidates have the same ranking.

In the party, the members who lost the election in the constituency more than once in a row and revived proportionally are placed in the position of "provisional branch chief", and every spring, the party member acquisition situation etc. are examined and it is decided whether to make it a formal branch chief. ing.Regarding the relevant candidates, in principle, we were considering a policy of not allowing duplicate candidacy with proportional representation in the next House of Representatives election.[5]However, there are no cases in which duplicate candidacy was not accepted for this reason.

New Frontier Party formed by the New Frontier Party, Komeito (composed of members of the House of Councilors, prefectural and local government members), and Ozawa Liberal Democratic Party (who belonged to the Komeito Party before the formation of the New Frontier Party) were reunited from October 1999. Along with his colleague Ozawa Liberal Party-Conservative (New) Party, he formed a coalition with the Liberal Democratic Party and cooperated in the election.

In the 2000 House of Representatives election, there were seven duplicate candidates.South Kanto block OfIsamu Ueda(Kanagawa 6 Wards)・Shigeyuki Tomita(Chiba 2 ward), The two "list" ranks are the same, 2rd place,Tokyo block OfYamaguchi Natsuo(Tokyo 17 Ward)・Otohiko Endo(Tokyo 4 Ward)・Yuriko Ohno(Tokyo 20 Ward), 3rd place with the same "Roster" ranking, 3 duplicate candidates in 2 proportional blocks, and they were in the same rank as each other (others)Shikoku blockIn second place aloneKochi 1 ward OfIshida Minoru,Northern Kanto blockIn second place aloneSaitama 6 Wards OfWakamatsu Kaneshige).However, all seven of the duplicate candidates were defeated in the single-seat constituency, and only two were Ueda and Wakamatsu who were revived as proportional representatives.

Since then, he has not run for duplicates since the 2003 lower house election, and has been running for either a single-seat constituency election or a proportional representation election.

Democratic Party

Formed in 1996Democratic PartyIn 1996, 2000, and 2003, duplicate candidates were placed in the same rank as possible in the proportional list, and in the past several cases were allowed to differ in the list rank among duplicate candidates, but in 2005 It was completely abolished from the House of Representatives election.However, it has been partially revived in the 2014 House of Representatives election.

In the past, there were some duplicate candidates at the top of the "list" (the 2000 House of Representatives election was changed from the single-seat constituency of the New Frontier Party).Saito GotoIn the New Frontier Party era, he was forced to run from the ward next to the single-seat constituency that he originally wanted as a proportional single candidate.Koriki JojimaIn the same Tokyo as Jojima, the former Democratic Party era was a proportional independent candidateYukihisa Fujita-Ishige, Run in a different constituency than the one in the old Democratic eraAkira Nagatsuma, In the 1996 House of Representatives electionPunchI changed the country from the constituency that was rejected as an incumbent to the next districtNoboru UsamiWas not given preferential treatment.

(In addition, Nagahama is in office21rd House of Councilors ordinary electionHe ran for the House of Representatives and lost his job.Osaka ran for the 2009 general election and was elected in the single-seat constituency. )

In the 2009 general electionDemocratic whirlwindIn response to this, it was expected that there would be a shortage of proportional representation candidates due to the large number of single-seat constituency candidates being elected, so we proceeded to support proportional representation candidates.As an exampleTohoku blockThen, all the single-seat constituency candidates were ranked first (except for Ichiro Ozawa mentioned above), and all the Democratic Party's single-seat constituency candidates were double-seat candidates, and seven people were placed below them.As a result, 1 people were elected in Tohoku, and 7 independent candidates were elected after deducting 7 proportional revival.

In the 2012 general election, a big headwind to the Democratic Party caused a large number of single-seat constituency candidates to be defeated, and ministers and party leaders could not make a proportional revival.In addition, the votes are broken due to the rush of political parties.Hokkaido blockAnd other than the Tohoku block, the voter turnout came in third.

However, in 2009, instead of reducing single-seat constituency candidates, it increased duplicate candidacy.Furthermore, in proportional districts other than Tokyo, the same ranking was set for the first time in the lower rank candidates.

Strong Points

Candidates who are not duplicate candidates are not guaranteed to be revived in proportional representation, so they will be elected in single-seat constituency elections.VotersThere is a merit that you have to be enthusiastic about appealing to.

In addition, since each single-seat constituency is always included as part of the proportional representation constituency, the more duplicate candidates there are, the more advantageous it is to carry in the constituency. ..

Furthermore, if the "list" ranking of duplicate candidates in the same proportional block is the same and the competition is made at the defeat rate, even if the single-seat constituency system ("single-seat constituency") cannot be won, another Just fight better than the candidateLoss rateIt is easy to maintain the hope that it can be revived with.In other wordsClose battle・ There is an advantage that it is easy to inspire the morale of the struggling candidates.

From the standpoint of the elector (voter), the possibility of a revival election in the proportional representation election can be considered in advance, so in the single-seat constituency election.Death voteIt can be said that it is a mechanism that can relieve the problem with a certain probability.Also,Article 67 of the Constitution of JapanSince it is stipulated in the Diet that "The Prime Minister will appoint this from among the members of the Diet by a resolution of the Diet."Party leaderIn the case of "the person selected by the people as the next prime minister cannot become the next prime minister due to the defeat in the constituency", "No matter how much the party that won the House of Representatives electionHead nominationIf the party leader runs for duplicate, the problem of "cannot be nominated by" will be resolved to some extent.However, the defeat of the single-seat constituency, a person who has shown one public opinion as "a person who is not suitable for a'national representative'", is a candidate for the prime minister, and there are doubts about his appointment.The Social Democratic Party in the 1 House of Representatives election is an example of a party leader losing a single-seat constituency and making a proportional revival.Takako DoiHowever, Doi was not voted in the nomination election because he resigned as leader immediately after the election.On the other hand, the single-seat constituency was defeated and a proportional revival was made.Mari EedaBecame the leader of the Democratic Party of Japan and got a vote in the nomination election for the leader.


It is believed that the duplicate candidates listed on the top of the "list" of the major political parties are almost guaranteed to win the revival.

For example, Liberal Democratic Party candidates have fallen below the 1996% voter turnout (which has become one of the requirements for a resurrection election since 10), which is the deposit forfeiture point, in the single-member constituency elections of the House of Representatives since 2000. Absent.The lowest voter turnout of LDP candidates in the lower house election single-seat constituency election was in the 1996 lower house election.Iwate 4rd districtThe voter turnout is 10.39%.Therefore, in the case of multiple candidates for the LDP, the condition of 10% or more of the total number of valid votes can usually be met almost certainly.

Therefore, in the case of duplicate candidates who are listed at the top of the "list" of proportional representation elections, there is a demerit that the enthusiasm for winning in the single-seat constituency system election district and the appeal to voters will be weakened. ..

In addition, if the number of duplicate candidates or single top candidates listed in the "list" of proportional representation elections increases, the loss rate in single-seat constituency elections will increase for many other (same rank) duplicate candidates. It has also been pointed out that the chances of winning a revival are relatively reduced.

For example,2000 House of Representatives electionThen, the Liberal Democratic Party is ranked high in the "list"Proportional representationSince there were many single candidates, the revival election of other duplicate candidates of the same rank wasHokkaido 9th district OfHirofumi Iwakura(Proportional Hokkaido),Kanagawa 14 Wards OfTaei Nakamoto(Proportional South Kanto),Chiba 8 ward OfYoshitaka Sakurada(Proportional South Kanto),Hyogo 1th Ward OfKeisuke Sunada(Kinki proportional) 4 people (laterAdvance winningDid12 wards of Osaka・ Kinki proportionalTomokazu KitagawaThere were only 5 people if you put in.

The Diet members are constitutionally "representatives of all the people" and not the representatives of the constituencies, but as a matter of fact, the votes obtained in the next election are of great concern.Normally, the members who have won the resurrection will aim to run from the constituency in the next election, so the constituency winners and the resurrection elected members will work for the benefit of the constituency, and the candidates for the small constituency Causes injustice with constituencies that have not won the resurrection.

Furthermore, by determining the ranking of the revival election based on the defeat rate, candidates with the highest number of votes will be defeated even if they are candidates of the same political party, and candidates with fewer votes will be elected.One vote disparityThe distortion is carried over to the proportional representation frame.


The same ranking of duplicate candidates is optional

If duplicate candidates are ranked the same, from the voter's point of view, they can partially participate in the ranking of the proportional list through elections.From the standpoint of a political party organization, there is a big disadvantage that it is extremely difficult to predict who will be revived and won in the sekihairitsu match of duplicate candidates in the same rank.As mentioned above, it is up to the political party to rank the duplicate candidates in the same order, so it is often the case that the political party avoids placing the duplicate candidates in the same rank.

Komeito, the Communist Party, and the former New Frontier Party avoid placing duplicate candidates in the same rank on the "list" as long as they are in the "list" proportional representation election (restricted list). It is based on the judgment of the party headquarters that the person who wants to be elected should be surely elected.

Therefore, in political parties that do not rank duplicate candidates in the same rank, the ranking does not change due to the defeat rate, and voters cannot partially participate in the ranking of the proportional list through elections.In the past, there are many cases in which candidates with a lower sekihairitsu rate were given preferential treatment in proportional order within the same proportional block, so they were revived and won (article "Article"Loss rate21 people from the Liberal Democratic Party, 11 people from the Communist Party, 6 people from the Democratic Party, 6 people from the Ishin no Kai, 2 people from the Social Democratic Party, 1 person from the Party of Hope, 1 person from the Liberal Party, and 1 person from the Future Party. A total of 49 people are applicable).

Resigned as a member of the House of Representatives and ran for a by-election in the House of Representatives

In the case of a member who was revived as a proportional representative election instead of a single-seat constituency election due to the double-member constituency system, if the other member elected in the single-seat constituency loses his job for some reason, he himself resigns from the position of a member of the House of Representatives and is elected as a substitute election ( There are times when you run for the House of Representatives single-member district system election.In this case, a very strange phenomenon occurs in which a person who should have resigned from the House of Representatives is running for the election of a member of the House of Representatives immediately after resigning from the House of Representatives.

However, due to the following factors, it is possible to resign as a member of the House of Representatives and run for a by-election in the House of Representatives.

First, even if a proportional representation member resigns, the runner-up candidate of the same party will be elected in advance, so even if the proportional representation member who resigned loses in the by-election, the party organization will be concerned with the seating power of the Diet. There are no disadvantages (there are disadvantages if there is no runner-up candidate who can win by-elections, but such cases are limited to winning elections more than the party expected, and there are few examples in the past).

In addition, if a political party has a candidate other than the proportional representation revival in a by-election, and that candidate is elected, one political party has two prospective candidates in a single-seat constituency where only one is elected. It is expected that the official adjustment of the next general election will be difficult.Therefore, in order for the party executives (party executives) and the proportional representation revival themselves to eliminate the issue of official adjustment in advance, the party headquarters supports and supports the candidacy of the proportional representation revival in the by-elections. The resurrected person also declares his candidacy until he resigns from the post of member of the House of Representatives without waiting for the next election of the House of Representatives.

This example is from 2002Fukuoka 6 wardsBy-electionKazunari Koga(Democratic Party), 2004Saitama 8 WardsBy-electionAtsushi Kinoshita(Democratic Party), 2008Yamaguchi 2th districtBy-electionHideo Hiraoka(Democratic Party), 2010Hokkaido 5th districtBy-electionNobutaka Machimura(Liberal Democratic Party), 2016Kyoto 3 wardsBy-electionKenta Izumi(Democratic Party) 5 times.When Issei Koga resigned, at that timeMinsuke WatanukiThe chairman of the House of Representatives did not accept the request for resignation, considering that the request for resignation was "to run for a by-election."However, even if the chairman did not accept it, there was no problem with the candidacy itself because the members of the Diet would lose their jobs when they submitted the candidacy for the by-election.Of these five, Hideo Hiraoka, Nobutaka Machimura, and Kenta Izumi were elected, but Issei Koga and Atsushi Kinoshita were defeated.

Restriction of duplicate candidacy due to political party requirements

As mentioned above, legally duplicate candidacy is limited to candidates for political parties that meet the party requirements.For this reason, it has been pointed out that candidates for political organizations that do not meet the requirements are unfair because their chances of winning are narrower than those of major political parties.For example, we have won candidates for proportional districts.New party earthDid not meet party requirements until 2011, so candidates for the party could not run twice in the 2005 and 2009 House of Representatives elections.

Seat relocation issue

Since the priority is given to winning in the single-seat constituency for duplicate candidates, if a political party wins more than expected, most of the duplicate candidates will be elected in the single-seat constituency and the remaining candidates will be proportional representations. It may not be possible to meet the number of seats won.In addition, while all the proportional blocks are candidates for duplication, there may be no candidates for proportional registration because all the candidates for the block are below the deposit forfeiture line.

In the past, the Liberal Democratic Party in 2005, the Democratic Party in 2009, and the Constitutional Democratic Party in 2017 had problems with the former, and the Your Party in 2009 had the latter problem. The seats have moved to the party.Of course, this relocation destination is determined regardless of the policy distance from the party from which it was relocated, so the Social Democratic Party candidate may be elected on behalf of the LDP, or the LDP candidate may be elected on behalf of the Constitutional Democratic Party.As a solution to this problem, there are alternatives such as allowing the addition of candidates and making them vacant, but each has its own problems and has not yet been realized.
