Open List Proportional Representation
An electoral system where voters can influence the order of candidates on a party's list by expressing preferences for individual candidates.

How It Works / What It Means in Practice
Open List Proportional Representation (OLPR) is a voting system designed to combine party proportionality with voter influence over individual candidates. Instead of voting solely for a party list predetermined by party officials, voters can express preferences for specific candidates within that list. This means that while seats are allocated to parties based on their overall share of the vote, the order in which candidates are awarded those seats depends on the number of personal votes each candidate receives.
In practice, voters receive ballots listing parties along with their candidates. Voters then mark not just their favored party, but also indicate their preferred candidates within that party. The total votes for a party determine how many seats it wins, while the candidates with the highest personal vote counts fill those seats. This system empowers voters to shape which individuals represent them, increasing accountability and responsiveness.
Why It Matters
OLPR enhances democratic representation by giving voters more control over who gets elected, rather than leaving candidate selection entirely to party elites. It encourages candidates to engage directly with voters to earn personal support, potentially improving the quality of representation. Also, because it retains proportionality, smaller parties can still gain fair representation, promoting pluralism.
By allowing voters to influence candidate rankings, OLPR can reduce party monopolies and foster intra-party competition. This can lead to more diverse legislative bodies and better alignment between elected officials and constituents’ preferences. It also mitigates some criticisms of closed-list systems, where voters feel disconnected from individual candidates.
Open List Proportional Representation vs Closed List Proportional Representation
While both systems allocate seats proportionally to parties, their key difference lies in voter influence over candidate selection. In closed list PR, parties set a fixed order of candidates on their list, and voters cannot change it. Seats won by a party go to candidates in the predetermined order, limiting voter choice.
In contrast, OLPR allows voters to reorder or select candidates within the party list, directly affecting which individuals are elected. This makes the system more candidate-centered and responsive to voter preferences. However, it can also introduce competition within parties, which some argue might undermine party cohesion.
Real-World Examples
Several countries use Open List Proportional Representation or variations thereof. For instance, Brazil employs an open list system where voters cast ballots for individual candidates, and seats are allocated proportionally based on party vote totals, with candidates ranked by personal votes. Finland and Sweden also use open lists, allowing voters to influence candidate order.
These systems have contributed to vibrant multiparty legislatures where voters have meaningful input on both party and candidate selection. However, the specific rules for expressing preferences and counting votes can vary across countries.
Common Misconceptions
One common misconception is that Open List PR completely eliminates party control over candidate selection. While voters can influence candidate rankings, parties still control which candidates appear on their lists and in what order initially.
Another misunderstanding is that OLPR always leads to fragmented legislatures or unstable governments. Although it encourages multiple parties and intra-party competition, many countries with OLPR maintain stable coalitions and effective governance.
Some also assume that open lists are more complicated for voters, but with clear ballot design and voter education, the system can be accessible and empowering.
Example
In Brazil's open list proportional representation system, voters cast ballots for individual candidates within party lists, directly influencing which candidates win seats in the legislature.
