Term limits
- See also: State legislatures with term limits
The Arizona legislature is one of 16 state legislatures with term limits. Voters enacted the Arizona Term Limits Act in 1992. That initiative said that Arizona senators are subject to term limits of no more than four two-year terms, or a total of eight years.
The first year that the term limits enacted in 1992 impacted the ability of incumbents to run for office was 2000.[9]
Vacancies
If there is a vacancy in the Arizona State Legislature, the board of county supervisors must select a replacement. The secretary of state is required to contact the state party chairperson to give notice of the vacancy. The state chairperson must give notice of a meeting to fill the seat within three business days of receiving notice.[10] The political party committee is involved in the appointment process only if the legislative district has thirty or more elected precinct committeemen.[10]
If the legislative district has 30 or more elected precinct committeemen:
- The precinct committeemen must nominate three qualified electors as replacements. If the Legislature is in session, this must occur within five days. If the Legislature is out of session, the committeemen have 21 days to nominate potential replacements. Each elector must receive a majority of the committeemen's vote to earn a nomination. The chair then forwards the three nominees to the board of supervisors. The board of supervisors appoints a nominee from the three names. If the committeemen do not submit a list of names within the allotted timeframe, the board of supervisors proceeds with the vacancy as if the district had fewer than 30 elected precinct committeemen.[10]
If the legislative district has fewer than 30 elected precinct committeemen:
- The board of supervisors appoints a panel of citizen supervisors within seven business days of a vacancy occurring. The citizen panel must submit the name of three qualified electors of the same political party as the previous incumbent to the board of supervisors. If the Legislature is in session, this must occur within five days. If the Legislature is out of session, the committeemen have 21 days to nominate potential replacements. The board of supervisors must select a replacement by a majority vote.[11]
- The person selected to fill the seat serves the remainder of the unfilled term.[11]
