Conditional (combination)
In a conditional method[1] whether one formula is used or not depends on the outcome of the other sub-method.
The term is used to describe a class of dependent mixed electoral systems.
Example
If a party has received 50% of the vote, it is receives all seats (party block voting), otherwise a partisan version of proportional representation is used.
Use
Pure conditional systems are not typically used, but supermixed systems such as majority jackpot or minority jackpot have a conditional element. The conditional system is distinguished from the correction model of dependent combination, where another formula always, unconditionally applies, but how it applies depends on the other subsystem.
Non-mixed systems
Many single-winner systems may also be conditional, such as the common two-round system, where the second round is only held if not candidate has received more than 50% of the vote.
