Political parties are in continual pursuit of updating the election procedures with a view to keeping functional or effective the politics of their country. Sometimes the underlying reason behind such updates might be the concern of not losing the power. On the other hand, these updates can occasionally stem from a necessity and become imperative. Frequently experienced political instabilities and dead-locks can lead to a reform in electoral systems which is injustice in representation.One of the electoral systems which make concessions to justice in representation for the sake of stability in government is the majority bonus system. This electoral system can be defined, as most concisely as possible, as the system in which a party rewarded with the highest number of votes from the electorate is rewarded once more with prize seats by the electoral system. This study has tried to facilitate better recognition of this electoral system through examining its practical outcomes in the light of the analyses conducted based on the data obtained from the countries where this electoral system is in effect.
