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.^[7]

Vacancies

See also: How vacancies are filled in state legislatures

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.^[8] The political party committee is involved in the appointment process only if the legislative district has thirty or more elected precinct committeemen.^[8]

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.^[8]

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.^[9]
The person selected to fill the seat serves the remainder of the unfilled term.^[9]

Redistricting

2020 redistricting cycle

See also: Redistricting in Arizona after the 2020 census

On January 24, 2022, Arizona enacted new legislative maps after the Arizona Independent Redistricting Commission transmitted its finalized plans to the secretary of state.^[10] The commission initially voted to finalize and certify the legislative map plan on Jan. 21.^[11] The commission's nonpartisan chairwoman, Erika Neuberg, joined the two Republican members—David Mehl and Douglas York—voting in favor of the map. The commission's two Democratic members—Shereen Lerner and Derrick Watchman—were opposed.^[12] This map took effect for Arizona's 2022 legislative elections.

The commission previously voted in favor of the legislative map by a 3-2 vote on December 22, 2021, which was followed by a period for counties to request administrative changes before the final vote on Jan. 21.^[13]

How does redistricting in Arizona work? The Arizona Independent Redistricting Commission is responsible for drawing both congressional and state legislative district lines. The commission is composed of five members. Of these, four are selected by the majority and minority leaders of each chamber of the state legislature from a list of 25 candidates nominated by the state commission on appellate court appointments. These 25 nominees comprise 10 Democrats, 10 Republicans, and 5 unaffiliated citizens. The four commission members appointed by legislative leaders then select the fifth member to round out the commission. The fifth member of the commission must belong to a different political party than the other commissioners. The governor, with a two-thirds vote in the Arizona State Senate, may remove a commissioner "for substantial neglect of duty, gross misconduct in office, or inability to discharge the duties of office." The Arizona State Legislature may make recommendations to the commission, but ultimate authority is vested with the commission.^[14]^[15]^[16]

The Arizona Constitution requires that both congressional and state legislative districts be "contiguous, geographically compact, and respect communities of interest–all to the extent practicable." The state constitution further mandates that district lines "should [follow] visible geographic features, city, town, and county boundaries, and undivided census tracts." In addition, the constitution requires that "competitive districts be favored where doing so would not significantly detract from the goals above."^[16]
