Open-List System
A proportional representation system where voters can influence the order of candidates on a party list.
Updated April 23, 2026
How It Works
In an open-list system, political parties present a list of candidates to voters, but unlike closed-list systems, voters have the power to influence the order in which candidates are elected. Instead of just voting for a party, voters can cast their ballots for individual candidates within the party list. The total votes for the party determine how many seats it wins, but the individual votes determine which candidates from that party fill those seats.
This system blends proportional representation with a degree of personal candidate choice, allowing voters to support both a party and specific individuals. Candidates who receive more preference votes can leapfrog others higher on the list, enabling popular candidates to be elected even if they were initially placed lower by the party.
Why It Matters
The open-list system enhances voter influence and accountability in proportional representation systems. It encourages candidates to engage directly with voters, fostering personal connections and responsiveness. This can lead to more competitive intra-party dynamics as candidates campaign not just to promote their party but also to secure personal votes.
Moreover, it can improve the representativeness of elected bodies by ensuring that popular candidates within parties get elected, reflecting voter preferences more accurately. This system also tends to reduce the control of party elites over candidate selection, promoting internal democracy within parties.
Open-List System vs Closed-List System
The primary difference is the degree of voter control over candidate selection. In a closed-list system, parties fix the order of candidates, and voters cannot alter it; they simply vote for a party, and seats are allocated according to the predetermined list order. Voters have no say in which individuals from the party get elected.
In contrast, the open-list system allows voters to affect candidate rankings by casting preference votes. This means candidates must appeal directly to voters, not just to party leadership. While closed lists emphasize party control and cohesion, open lists prioritize voter choice and candidate accountability.
Real-World Examples
Countries like Brazil, Finland, and Sweden use open-list proportional representation systems. In Brazil, for instance, voters select individual candidates from party lists for the Chamber of Deputies, and seats are allocated proportionally based on the total votes each party receives.
This system has shaped political competition by encouraging candidates to build personal support networks and engage in grassroots campaigning, often leading to diverse representation within parties.
Common Misconceptions
One common misconception is that an open-list system eliminates the role of political parties. While voters do choose individual candidates, the party's overall vote total still determines the number of seats it gains. Parties remain central to organizing candidates and campaigns.
Another misconception is that open-list systems always lead to intra-party conflict. While competition among candidates can increase, parties often manage candidate selection and campaigning to balance competition with unity.
Finally, some believe open lists guarantee that the most popular candidates always get elected. However, strategic voting, party strategies, and electoral thresholds can still influence outcomes, meaning voter preferences are one of several factors shaping results.
Example
In Sweden's open-list system, voters select individual candidates within party lists, allowing popular candidates to be elected regardless of their initial list position.
