Open list describes any variant of party-list proportional representation where voters have at least some influence on the order in which a party's candidates are elected. This is as opposed to closed list, in which party lists are in a predetermined, fixed order by the time of the election and gives the general voter no influence at all on the position of the candidates placed on the party list.
An open list system allows voters to select individuals rather than, or in addition to parties. Different systems give the voter different amounts of influence to change the default ranking. The voter's candidate choices are usually called preference vote; the voters are usually allowed one or more preference votes for the open list candidates.
Open lists differ from mixed-member proportional representation, also known as "personalized proportional representation" in Germany. Some mixed systems, however, may use open lists in their list-PR component.
A "relatively closed" open list system is one where a candidate must reach a full electoral quota of votes on their own to be assured of winning a seat. The total number of seats won by the party minus the number of its candidates that achieved this quota gives the number of unfilled seats. These are then successively allocated to the party's not-yet-elected candidates who were ranked highest on the party list.
Iceland: In both parliamentary and municipal elections, voters may alter the order of the party list or strike candidates from the list completely. How many votes need to be altered in this way to have an effect on the results varies by the number of seats won by the party in the constituency or municipality in question and the candidate's place on the list. [1] In the parliamentary elections of 2007 and 2009, voters altered the party lists enough to change the ranking of candidates within party lists. However, this did not affect which candidates ultimately got elected to parliament. [2]
Norway: In parliamentary elections, 50% of the voters need to vote for a candidate in order to change the order of the party list, meaning that, in practice, it is almost impossible for voters to change the result and it is de facto a closed list system. In county elections there is a threshold of 8%. [3]
In a "more open" list system, the quota for election could be lowered from the above amount. It is then (theoretically) possible that more of a party's candidates achieve this quota than the total seats won by the party. It should therefore be made clear in advance whether list ranking or absolute votes take precedence in that case. The quota for individuals is usually specified either as a percentage of the party list quota, or as a percentage of the total votes received by the party.
Example: The quota is 1000 votes and the open list threshold is specified as 25% of the quota, i.e. 250 votes. Therefore, a party which received 5000 votes wins five seats, which are awarded to its list candidates as follows:
Candidate position on the list | Preference votes | 25% of the quota | Elected |
---|---|---|---|
#1 | 3500 | x (first) | x |
#2 | 50 | x | |
#3 | 150 | x | |
#4 | 250 | x (third) | x |
#5 | 100 | ||
#6 | 100 | ||
#7 | 450 | x (second) | x |
#8 | 50 | ||
Candidates #1, #7 and #4 have each achieved 25% of the quota (250 preference votes or more). They get the first three of the five seats the party has won. The other two seats will be taken by #2 and #3, the two highest remaining positions on the party list. This means that #5 is not elected even though being the fifth on the list and having more preference votes than #2.
In practice, with such a strict threshold, only very few candidates succeed to precede on their lists as the required number of votes is huge. Where the threshold is lower (e.g. in Czech parliamentary elections, 5% of the total party vote is the required minimum), results defying the original list order are much more common.
Parties usually allow candidates to ask for preference votes, but without campaigning negatively against other candidates on the list.
The members of the National Council are elected by open list proportional representation in nine multi-member constituencies based on the states (with varying in size from 7 to 36 seats) and 39 districts. Voters are able to cast a single party vote and one preference votes each on the federal, state and electoral district level for their preferred candidates within that party. The thresholds for a candidate to move up the list are 7% of the candidate's party result on the federal level, 10% on the state level and 14% on the electoral district level. [4] Candidates for the district level are listed on the ballot while voters need to write-in their preferred candidate on state and federal level.
In Croatia, the voter can give their vote to a single candidate on the list, but only candidates who have received at least 10% of the party's votes take precedence over the other candidates on the list. [5]
In Czech parliamentary elections, voters are given 4 preference votes. Only candidates who have received more than 5% of preferential votes at the regional level take precedence over the list. [6] For elections to the European Parliament, the procedure is identical but each voter is only allowed 2 preference votes.
In Indonesia, any candidate who has obtained at least 30% of the quota is automatically elected. [7] [ needs update ]
In the Netherlands, the voter can give their vote to any candidate in a list (for example, in elections for the House of the Representatives); the vote for this candidate is called a "preference vote" (voorkeurstem in Dutch). Candidates with at least 25% of the quota takes priority over the party's other candidates who stand higher on the party list but received fewer preference votes. Most people vote for the top candidate, to indicate no special preference for any individual candidate, but support for the party in general. Sometimes, however, people want to express their support for a particular person. Many women, for example, vote for the first woman on the list. If a candidate gathers enough preference votes, then they get a seat in parliament, even if their position on the list would leave them without a seat. In the 2003 elections Hilbrand Nawijn, the former minister of migration and integration, was elected into parliament for the Pim Fortuyn List by preference votes even though he was the last candidate on the list.
In Slovakia, each voter may, in addition to the party, select one to four candidates from the ordered party list. Candidates who are selected by more than 3% of the party's voters are elected (in order of total number of votes) first and only then is the party ordering used. For European elections, voters select two candidates and the candidates must have more than 10% of the total votes to override the party list. In the European election in 2009 three of Slovakia's thirteen MEPs were elected solely by virtue of preference votes (having party-list positions too low to have won otherwise) and only one (Katarína Neveďalová of SMER) was elected solely by virtue of her position on the party list (having fewer preference votes than a number of other candidates who themselves, nevertheless had preferences from fewer than 10 percent of their party's voters).
In Sweden, a person needs to receive 5% of the party's votes for the personal vote to overrule the ordering on the party list. [8] Voting without expressing a preference between individuals is possible, although the parties urge their voters to support the party's prime candidate, to protect them from being beaten by someone ranked lower by the party. The share of voters using the open list option at 2022 Swedish general election was 22.49%. [9]
The most-open list, fully-open list, or simply open list system is one where the number of votes for each candidate fully determines the order of election. This system is used in all Finnish, Latvian, and Brazilian multiple-seat elections. Since 2001, lists of this "most open" type have also been used in the elections to fill the 96 proportional seats in the 242-member upper house of Japan.[ citation needed ]
A "free list", more usually called panachage or mixed list, is a variant on the most open list where voters may support candidates on different lists. Candidates are typically elected using either cumulative or block plurality voting. This gives the voters full control over which candidates are elected, not just within a particular party, but even across them. As a result, independents are not forced to support candidates of only one party, and can support candidates across multiple lists, while still ensuring the results are ultimately proportional. [11]
It is used in elections at all levels in Liechtenstein, Luxembourg, and Switzerland, in congressional elections in Ecuador, El Salvador, and Honduras, as well as in local elections in a majority of German states, in French communes with under 1,000 inhabitants, and in Czech municipal elections.[ citation needed ]
Some ways to operate an open list system when using traditional paper-based voting are as follows:
Some of these states may use other systems in addition to an open list, for example first-past-the-post in individual constituencies. Some countries use open list may only be used in one of the chambers of the legislature.

Proportional representation (PR) refers to any type of electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to political divisions among voters. The essence of such systems is that all votes cast – or almost all votes cast – contribute to the result and are effectively used to help elect someone. Under other election systems, a bare plurality or a scant majority are all that are used to elect candidates. PR systems provide balanced representation to different factions, reflecting how votes are cast.
Party-list proportional representation (list-PR) is a system of proportional representation based on preregistered political parties, with each party being allocated a certain number of seats roughly proportional to their share of the vote.
The single transferable vote (STV) or proportional-ranked choice voting (P-RCV), is a multi-winner electoral system in which each voter casts a single vote in the form of a ranked ballot. Voters have the option to rank candidates, and their vote may be transferred according to alternative preferences if their preferred candidate is eliminated or elected with surplus votes, so that their vote is used to elect someone they prefer over others in the running. STV aims to approach proportional representation based on votes cast in the district where it is used, so that each vote is worth about the same as another.
The electoral threshold, or election threshold, is the minimum share of votes that a candidate or political party requires before they become entitled to representation or additional seats in a legislature.
Single non-transferable vote or SNTV is an electoral system used to elect multiple winners. It is a semi-proportional variant of first-past-the-post voting, applied to multi-member districts where each voter casts just one vote. SNTV generally makes it unlikely that a single party will take all seats in a city, as generally happens with winner-take-all systems. SNTV can be considered a variant of dot voting where each voter has only one point to assign.
Voting refers to the process of choosing officials or policies by casting a ballot, a document used by people to formally express their preferences. Republics and representative democracies are governments where the population chooses representatives by voting.
In the study of apportionment, the Harequota is the number of voters represented by each legislator under an idealized system of proportional representation, where every legislator represents an equal number of voters and where every vote is used to elect someone. The Hare quota is the total number of votes divided by the number of seats to be filled. The Hare quota was used in the original proposal for a single transferable vote system, and is still occasionally used, although it has since been largely supplanted by the Droop quota.
Regular elections in Albania are mandated by the Constitution and legislation enacted by Parliament. The Parliament (Kuvendi) has 140 members elected for four-year terms. The electoral system is open list proportional representation. There are 12 multi-member constituencies corresponding to the country's 12 administrative regions. Within any constituency, parties must meet a threshold of 3 percent of votes, and pre-election coalitions must meet a threshold of 5 percent of votes.
In electoral systems, a wasted vote is any vote cast that is not "used" to elect a winner, and so is not represented in the outcome. However, the term is vague and ill-defined, having been used to refer to a wide variety of unrelated concepts and metrics. The precise definition of a wasted vote can have a major impact on the conclusions of an analysis. For example, under the narrowest possible definition of a wasted vote, the single transferable vote (STV) can be considered to waste zero votes. However, if the wasted vote definition is expanded even slightly, it is possible for up to 100% of STV votes to be classified as wasted because STV fails the unanimity criterion; that is, it is possible to elect a legislature that every single voter agrees is worse than some alternative.
The National Assembly is the lower chamber of Parliament in Burundi. It consists of 100 directly elected members and between 18 and 23 co-opted members who serve five-year terms.
The Federal National Council (FNC) of the United Arab Emirates (UAE) is an advisory quasi-parliamentary body in the UAE. The FNC consists of 40 members. Twenty of the members are indirectly elected by the hand-picked 33% of Emirati citizens who have voting rights through an electoral college, while the other twenty are appointed by the rulers of each emirate. According to Reuters, "the process of selecting the people who can either elect or be elected is opaque."
General elections were held in Guyana on 19 March 2001. The result was a victory for the People's Progressive Party/Civic, which won 34 of the 65 seats. Voter turnout was 91.7%.
There are a number of complications and issues surrounding the application and use of single transferable vote proportional representation that form the basis of discussions between its advocates and detractors.
Parliamentary elections were held in Djibouti on 8 February 2008. There were 65 candidates running for the 65 seats in the National Assembly, with all of the candidates coming from the ruling coalition, the Union for the Presidential Majority (UMP). The opposition boycotted the election, and the UMP won all 65 seats.
An electoral or voting system is a set of rules used to determine the results of an election. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, non-profit organisations and informal organisations. These rules govern all aspects of the voting process: when elections occur, who is allowed to vote, who can stand as a candidate, how ballots are marked and cast, how the ballots are counted, how votes translate into the election outcome, limits on campaign spending, and other factors that can affect the result. Political electoral systems are defined by constitutions and electoral laws, are typically conducted by election commissions, and can use multiple types of elections for different offices.
Parliamentary elections were held in Armenia on 2 April 2017. They were the first elections after a constitutional referendum in 2015 that approved reforms for the country to become a parliamentary republic. The result was a victory for the ruling Republican Party of Armenia, which won 58 of the 105 seats in the National Assembly.
Parliamentary elections were held in Cyprus on 30 May 2021 to elect 56 of the 80 Members of the House of Representatives.
A gender quota is a quota used by countries and parties to increase women's representation or substantive equality based on gender in legislatures. Women are largely underrepresented in parliaments and account for a 26.9% average in parliaments globally. As of November 2021, gender quotas have been adopted in 132 countries. Around the world, quotas vary greatly in their enforcement and the stage of electoral process targeted, creating three main types of quotas: legislated candidate quotas, voluntary party quotas, and reserved seats. Regardless of their prevalence, they are a controversial measure, creating debates concerning their impacts, both negative and positive.
Parliamentary elections are to be held in Slovenia no later than 24 April 2026.
