The Arizona Constitution is the state’s supreme governing document, adopted when Arizona entered the Union on February 14, 1912, and it sets up a government in which ordinary voters hold unusually direct power over laws, officeholders, and the constitution itself.1United States Senate. Arizona – Senate.gov It organizes the state into legislative, executive, and judicial branches, protects individual rights in terms that often reach further than the federal Bill of Rights, and reserves to the public the tools of initiative, referendum, and recall.
What the Declaration of Rights Protects
Article 2 is Arizona’s version of the Bill of Rights, and it binds state and local government rather than Washington. Several provisions use language more explicit than the federal text, which gives Arizona courts independent ground for their rulings.
Section 8 says no person shall be disturbed in their private affairs or have their home invaded without authority of law.2Arizona Legislature. Arizona State Constitution That direct wording gives state courts a textual basis for evaluating searches and surveillance separate from Fourth Amendment analysis.
Section 26 protects the right to bear arms in defense of self or state and prohibits any individual or corporation from organizing, maintaining, or employing a private armed force.3FindLaw. Arizona Constitution Art. II Sect. 26 – Bearing Arms The section does not itself authorize the legislature to regulate how weapons are carried; any such regulation comes from the legislature’s general police power.
Crime Victims’ Rights
Article 2, Section 2.1 embeds a Victims’ Bill of Rights directly in the constitution. Crime victims are entitled to be treated with fairness and dignity, to be present at any proceeding where the defendant has the right to be present, and to be heard at bail, plea, and sentencing hearings. Victims can refuse defense interviews or depositions, receive prompt restitution from the convicted person, and be notified if the accused escapes or is released. If the direct victim is killed or incapacitated, a spouse, parent, child, or other lawful representative stands in their place.4Arizona Legislature. Arizona Constitution Article 2 Section 2.1
How Laws Get Made in Arizona
Lawmaking power is split between the legislature and the voters. The Arizona State Legislature has 30 senators and 60 representatives drawn from 30 legislative districts, with each district sending one senator and two representatives.5Arizona Legislature. Arizona State Legislature Members serve two-year terms and may not hold more than four consecutive terms in the same chamber, a cap of eight consecutive years in the House or eight in the Senate.6Arizona Legislature. Arizona Constitution Article IV Part 2 Section 21 After one full term out of office, a former legislator can run again for the same seat.
Initiative and Referendum
Article 4, Part 1 reserves two tools for the public. Through the initiative, voters can propose a new statute by collecting signatures equal to 10 percent of the votes cast in the most recent gubernatorial election, or propose a constitutional amendment with signatures equal to 15 percent of that same total.7FindLaw. Arizona Constitution Art. 4 Pt. 1 Sect. 1 – Legislative Authority; Initiative and Referendum Every initiative must embrace only one subject, a requirement voters added in 2022 to stop organizers from bundling unrelated provisions into one ballot measure.
The referendum runs the other direction. When the legislature passes a law voters want to challenge, citizens have 90 days after the legislative session adjourns to collect signatures equal to 5 percent of the last gubernatorial vote total.8Arizona Secretary of State. Referendum If the signatures check out, the law is suspended and placed on the next general election ballot, where voters decide whether it stands or falls.
The Voter Protection Act
Voters adopted a provision in 1998, commonly called the Voter Protection Act, that limits the legislature’s ability to tamper with laws passed at the ballot box. The legislature cannot supersede a voter-approved initiative or referendum unless three-fourths of each chamber votes in favor and the new legislation furthers the purposes of the original measure.9Arizona Legislature. Proposition 105 Requirements That is an exceptionally high bar, and it leaves the legislature little room to undo or soften what voters have enacted.
A Plural Executive, Not a Single Boss
Arizona does not concentrate executive power in the governor. Article 5 names the governor, lieutenant governor, secretary of state, attorney general, state treasurer, and superintendent of public instruction as the core of the executive department, each elected independently statewide.10Arizona Legislature. Arizona Constitution Article 5 Section 1 The lieutenant governor is a recent addition, with the first election for the office scheduled during the 2026 cycle.
Because each officer carries a separate mandate from voters, the attorney general can take legal positions that depart from the governor’s agenda, and the superintendent of public instruction can pursue education policies the governor does not favor. The state treasurer manages billions in public assets under constitutional constraints on public funds. The structure prevents any one executive from controlling all arms of state administration, and it can also produce friction when independently elected officers disagree.
The secretary of state runs elections and keeps official executive records. The office historically stood first in line to succeed the governor, an order that shifts with the creation of the lieutenant governor position. The governor can veto legislation, and the legislature may override a veto only with a two-thirds vote of each chamber.
Courts and How Arizona Picks Its Judges
The court system runs in a straightforward hierarchy. The Supreme Court sits at the top, hearing appeals on major legal questions and supervising the judicial branch. The Court of Appeals reviews lower-court decisions for legal error. The Superior Court is the general trial court, handling felony criminal cases and civil disputes above $10,000.11Arizona Judicial Branch. Limited Jurisdiction Courts
Merit Selection and Retention Elections
In counties with populations above 250,000, judges reach the bench through merit selection rather than partisan election. A nonpartisan commission reviews applicants and sends the governor at least three names, which cannot all come from the same political party.12Arizona Judicial Branch. Constitutional Provisions The commission itself is chaired by the chief justice of the Supreme Court and includes five attorney members from different supervisorial districts and ten nonattorney members. The governor appoints one nominee from the list.
Once appointed, a judge serves a four-year term and then faces a retention election, where voters answer yes or no on keeping that judge in office.12Arizona Judicial Branch. Constitutional Provisions No opponent appears on the ballot. In smaller counties, judges still run in contested elections.
Judicial Discipline
A Commission on Judicial Conduct investigates complaints against sitting judges and can recommend to the Supreme Court that a judge be censured, suspended without pay, or removed from office for misconduct. A judge may also be involuntarily retired for a mental or physical incapacity that seriously interferes with the job and is likely permanent. If a judge pleads guilty to or is convicted of a felony or a crime involving dishonesty, the Supreme Court can suspend the judge without salary on its own initiative.
The Corporation Commission
Arizona is one of only a handful of states with a constitutionally established corporation commission that operates independently of the governor, the legislature, and the courts.13Arizona Corporation Commission. About the Commission Created at statehood in 1912, it has five members elected statewide to four-year terms, with a limit of two consecutive terms.14Arizona Legislature. Arizona Constitution Article 15 Section 1 If a seat opens mid-term, the governor appoints a replacement who serves until a commissioner is chosen at the next general election.
The commission regulates investor-owned utilities and private water and wastewater companies. It sets rates, approves service changes, and reviews applications for major infrastructure like power plants generating more than 100 megawatts.15Arizona Corporation Commission. Utilities FAQs Municipal utilities, the Salt River Project’s rate-setting, and wireless or internet services fall outside its jurisdiction. Because its authority is constitutional, the governor cannot fire commissioners and the legislature cannot simply abolish the body.
Taxes, Debt, and Spending Limits
Article 9 puts hard numerical limits on how state and local government raise and spend money.
Residential property taxes are capped at 1 percent of the property’s full cash value in any given year. The cap does not cover taxes levied to repay voter-approved bonds, special assessment districts, or levies voters have approved to exceed a budget or tax limitation.16FindLaw. Arizona Constitution Art. IX Sect. 18 – Residential Ad Valorem Tax Limits A homeowner’s total bill can run above 1 percent when bond repayment and special district assessments stack on top of the base levy.
Total state debt is capped at $350,000, a figure set in 1912 and never adjusted.17FindLaw. Arizona Constitution Art. IX Sect. 5 – Power of State to Contract Debts Money borrowed under that cap can be used only to cover revenue shortfalls or unanticipated expenses, with the sole exception of unlimited borrowing to repel invasion, suppress insurrection, or defend the state in wartime. In practice the state works around the cap through revenue bonds and other financing that falls outside the constitutional definition of general obligation debt.
Counties, cities, and towns operate under expenditure limits tied to their actual spending of local revenues in fiscal year 1979–1980, adjusted each year for changes in population and the cost of living.18Arizona Legislature. Arizona Constitution Article 9 Section 20 – Expenditure Limitation A local governing board cannot exceed its adjusted limit unless voters approve an override or a declared disaster triggers emergency spending authority. The Economic Estimates Commission publishes each jurisdiction’s ceiling before April 1 of every year.19Arizona Auditor General. Uniform Expenditure Reporting System (UERS)
Counties and Charter Cities
Article 12 requires every organized county to elect a sheriff, county attorney, recorder, treasurer, assessor, superintendent of schools, and at least three supervisors. Each serves a four-year term, and supervisors are nominated and elected from districts rather than at large.20Justia Law. Arizona Constitution Article 12 Section 3 – County Officers; Election; Term of Office The legislature can add supervisors beyond three but cannot eliminate any of the required offices.
Cities with more than 3,500 residents may adopt a home-rule charter, essentially a local constitution. The process begins with electing a 14-member board of freeholders, who have 90 days to draft the proposed charter; voters then ratify it, and the governor must approve it as consistent with state law and the constitution.21FindLaw. Arizona Constitution Art. XIII Sect. 2 – Charter Once adopted, a charter becomes the city’s organic law and supersedes conflicting local ordinances. Charter cities still cannot override specific constitutional restrictions, including those on public debt and taxation.
How the Constitution Gets Changed
Every change to the Arizona Constitution must be approved by voters. There is no amendment path that bypasses a public vote.
Legislative Referral
The legislature can put a proposed amendment on the ballot with a simple majority of the members elected to both chambers. The proposal is entered on each chamber’s journal with a recorded roll-call vote, and the secretary of state submits it to voters at the next general election or at a special election if the legislature calls one.22Arizona Legislature. Arizona Constitution Article 21 Section 1 The proposed amendment must be published in at least one newspaper in every county for at least 90 days before the election.
Citizen-Initiated Amendments
Voters can skip the legislature entirely by collecting signatures equal to 15 percent of the total votes cast for all candidates for governor in the last general election.22Arizona Legislature. Arizona Constitution Article 21 Section 1 That threshold sits above the 10 percent needed for a statutory initiative, reflecting the greater weight of amending the constitution itself.7FindLaw. Arizona Constitution Art. 4 Pt. 1 Sect. 1 – Legislative Authority; Initiative and Referendum Once the signatures are validated, the proposed amendment goes to voters at the next general election.
Approval Threshold
Most proposed amendments pass with a simple majority of those voting on the question. One exception matters: any amendment approving a new tax requires approval from 60 percent of voters.22Arizona Legislature. Arizona Constitution Article 21 Section 1 When multiple amendments appear on the same ballot, voters consider each separately.
Recalling Elected Officers
Under Article 8, every elected public officer in Arizona is subject to recall after serving at least six months in office. For legislators, a recall petition may be circulated just five days after the first legislative session following their election.23Arizona Secretary of State. Recall Quick Reference Guide To trigger a recall election, organizers must collect signatures from qualified electors equal to 25 percent of the total votes cast for all candidates for that office at the last general election, divided by the number of seats filled. After one recall attempt and election, no further recall petition may be filed against the same officer during that term unless the new petitioners first reimburse the public treasury for the cost of the prior recall election.
The recall power reaches every elected office in the state, from city council to the governor. Combined with the initiative, the referendum, and mandatory voter approval of every constitutional amendment, it leaves Arizona voters with some of the most direct control over government found in any state.
