The majority jackpot system (MJS), also known as majority-minority apportionment is a mixed-member majoritarian voting method. It provides for semi-proportional representation by giving a certain number (usually more than a majority) of seats in a legislature to a certain party or alliance, with the aim of providing government stability. The majority jackpot is typically classified a mixed electoral system, as it combines the proportional and winner-take-all system by a principle called fusion[1]. This is different from parallel voting (superposition) and coexistence. A majority jackpot can also be considered a supermixed system, since it usually has a conditional and corrective element. This differentiated in from the similar majority bonus system.
It is currently used in Armenia, San Marino, and formerly in Italy from 2006 to 2013.[citation needed]
