Technically, almost all of the parliamentary electoral systems applied in CoE member states are in line with democratic standards. However, there are some democratic objections to the use of electoral systems awarding bonus seats. Bonus seats are awarded to a party in addition to seats won by the normal procedure in use for allocating seats. Italy had a lot of experience with different electoral systems using “majority prizes” assigned to the largest parties or coalitions. Until 2019, Greece used a “reinforced” PR system, granting 50 additional “bonus seats” to the leading party. In San Marino where a PR system with preferential voting in a single nationwide constituency and a 5% threshold for seat allocation are applied, a “stability reward“ still assures that the winning coalition receives at least 35 of 60 seats in the parliament (Grand and General Council). While the purpose of bonus systems is to strengthen the winning party to (make it easier to) secure an overall parliamentary majority and thereby to promote government stability, the awarding of bonus seats could be criticised for being inconsistent with the expression of popular preferences in direct elections. However, it must be admitted that many electoral systems inherently give larger parties a certain advantage.
