House and Senate election districts are determined on the basis of population. A member of the Legislature must be a qualified voter who has been residing in Alaska for no less than three years, and a resident of the district from which elected for one year immediately preceding filing for office. A senator must be at least 25 years old and a representative 21 years of age at the time the oath of office is taken. Each house is the final judge of the qualifications and election of its members and may expel a member with the concurrence of two-thirds of the membership of the house. A legislator formally becomes a member when the oath of office is taken and when seated at the convening of the next regular legislative session after the election.
Provision is made for filling legislative vacancies by appointment or election.
