When electing multiple candidates to a board or committee Proportional Approval Voting ensures that no single voting group dominates the outcome, promoting fair representation and reflecting the diverse preferences of all voters. In scenarios where there are more seats than choices available and where each choice represents a party—this method can allow a popular party to be allocated multiple seats proportionally, mirroring the party’s share of overall support.
