A by-election or bye-election is a type of special election. These elections are held in between general elections. General elections are elections for all members of an elected body. By-elections are elections for just some members. A by-election could be needed if a member dies or resigns while in political office. They are also used if a person is removed from office for some reason, for example if he/she is guilty of a crime or is not qualified to be a member anymore.
