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 as opposed to closed list, which allows only active members, party officials, or consultants to determine the order of its candidates and gives the general voter no influence at all on the position of the candidates placed on the party list. Additionally, an open list system can also allow a voter the alternative of voting for the party as a whole without expressing a preference between individuals. There are differences possible between varying open list systems, each giving the voter varying amounts of influence. Voter's choice is usually called preference vote.
List Systems 
Relatively closed list 
A "relatively closed" open list system is one where initially a candidate has to get a full quota on his or her own (ie very broadly, the total number of votes cast divided by the number of places to be filled) in order to be elected (usually the precise number required is the Hare quota, but use of the Droop quota is also possible). 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 would then successively be allocated to those not yet elected candidates from that party who had been ranked highest on the original list.
More open list 
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.
In Dutch elections (for example to the House of the Representatives) the voter can give his vote to any candidate in a list; the vote for this candidate is called a "preference vote" (voorkeurstem in Dutch). If a candidate has at least 25% of the quota then he/she takes priority over the party's other candidates who stand higher on the party list but received fewer preference votes.
An example: A party list got 5000 votes. If the quota is 1000 votes, then the party wins five seats.
on the list
|Preference votes||25% of the quota||Elected|
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, at the national level only one or two candidates can precede on their lists[clarification needed]. This happens more often at the local level where the quota (in absolute numbers of votes) is lower. Parties usually allow candidates to ask for preference votes, but without campaigning negatively against other candidates on the list.
In elections in Sweden, the 'most open' list is used, but a person needs to receive 5% of the party's votes (in elections to the European Parliament, municipal assemblies or county councils) or 8% of the party's votes (in elections to the Riksdag) for the personal vote to overrule the ordering on the party list. 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.
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 (the most recent election run under this system) 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 the Netherlands, a country with an open list proportional representation system, 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 he gets a seat in parliament, even if his position on the list would leave him 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.
A country could introduce a version of a more open list voting system allowing parties to choose a small number (say, 5 or 10) of candidates to be guaranteed to be selected first (perhaps to form a small 'core' of government, such as head of state, cabinet, etc.) This solves the problem of major party figures being prevented from taking office, yet still allows the vast majority of party candidates' order on the party list to be decided by the voters.
Most open list 
The 'most open' list system is the one where the absolute amount of votes every candidate receives fully determines the "order of election" (the list ranking only possibly serving as a 'tiebreaker'). When such a system is used, one could make the case that within every party an additional virtual single non-transferable vote election is taking place. This system is used in all Finnish and Brazilian multiple-seat elections. While ties may be resolved by a toss in Finland, the oldest candidate wins the tie in Brazil.
Free list 
A 'free list' is similar in principle to the most open list, but instead of having just one vote for one candidate in one list, an elector has (usually) as many votes as there are seats to be filled, and may distribute these among different candidates in different lists. Electors may also give more votes to one candidate, in a manner similar to cumulative voting. This gives the elector more control over which candidates are elected.
Arbitrary list 
In an Arbitrary List system, political parties may put their candidates on the list in a fixed place, and may leave some places on the list empty, and some candidates unplaced. Each empty place on the list that needs to be filled, will be filled by the unplaced candidate who got the most votes. It is only possible to vote for unplaced candidates. Hence, having only one candidate unplaced is identical to having all candidates placed.
For example: In one constituency (electoral district), four parties (A to D) may nominate up to five candidates each, and a total of 10 MPs will be elected. Party A gets 40 percent of the vote, so gets 4 representatives elected, so the preference votes have no effect - if less than 4 were elected, they would have had an effect. Party B gets 30 percent of the vote, getting 3 representatives elected, but their preference votes would only have had an effect if only 1 candidate was elected. Party C gets 20 percent of the vote, and the preference votes determine which of the 2 unplaced candidates get elected. In the case of party D, there is only one candidate to whom votes may be given, so the candidate could equally well have been fixed on the list.

Practical operation 
Some ways to operate an open list system when using traditional paper-based voting are as follows:
- One method (used in Belgium) is to have a large ballot paper with a box for each party and sub-boxes for the various candidates.
- Another method (used in Slovakia) is to have a separate ballot paper for each party. To maintain voter secrecy, the voter is handed ballot papers for every party. The voter chooses the candidates (or may vote for the party as a whole) on one of the ballot papers and puts that paper into an envelope, putting the envelope into the ballot box, and discarding the other ballot papers into a bin provided for that purpose.
- In Brazil, each candidate is assigned a number (in which the first 2 digits are the party number and the others the candidate's number within the party). The voting machine has a telephone-like panel where the voter presses the buttons for the number of their chosen candidate. In Finland, each candidate is assigned a 3-digit number.
- In Italy, the voter must write the name of each chosen candidate in blank boxes under the party box.
