Leveling Seats
Leveling Seats are a mechanism used in some electoral systems to ensure a more proportional representation of political parties in legislative bodies. These seats are added to the number of seats that would normally be elected through direct constituencies or electoral districts, aiming to adjust the distribution of seats in line with the parties' overall vote share.
History and Development
The concept of leveling seats has its roots in efforts to refine Proportional Representation systems. Initially, many countries adopted straightforward proportional systems where the number of seats allocated to each party was based directly on the percentage of votes they received. However, this often led to issues with small parties or wasted votes, prompting the development of compensatory mechanisms like leveling seats.
- Germany: One of the earliest adopters of leveling seats was Germany with its Mixed-Member Proportional System (MMP). Introduced post-World War II, the German system uses leveling seats to correct disparities between first-past-the-post district results and the proportional vote share.
- New Zealand: Following Germany's example, New Zealand implemented leveling seats in its MMP system in 1996, aiming to ensure a more equitable representation of voter preferences.
Mechanism
The process of allocating leveling seats typically involves:
- Calculating the total number of seats each party should receive based on the percentage of votes they got in the election.
- Comparing this number to the actual seats won in the constituencies or districts.
- Adding additional seats, known as leveling seats, to parties that have won fewer seats than their proportional share would indicate.
This adjustment can be done in various ways:
- Through a second ballot or list system where voters also choose a party list, which is used to allocate additional seats.
- Directly from a national list of candidates provided by parties, where these candidates fill the leveling seats.
Advantages and Criticisms
Advantages:
- Reduces the Wasted Vote phenomenon, where votes for smaller parties or candidates in non-competitive districts do not contribute to representation.
- Enhances the proportionality of the election results, making the parliament's composition more reflective of the electorate's will.
Criticisms:
- Can lead to an increase in the size of the legislature, which some argue is less efficient or more costly.
- Complexity in understanding the system might reduce voter engagement or satisfaction with the electoral process.
Examples
- In Germany, if a party wins more seats via direct mandates than their proportional share would suggest, these extra seats are added to the parliament, and leveling seats are used to compensate other parties accordingly.
- New Zealand's MMP system ensures that if a party does not win enough electorate seats to match its party vote share, additional members are elected from party lists to achieve proportionality.
