The structure of California state government divides power among three branches: a two-chamber legislature that writes state law, a plural executive of eight separately elected officers led by the Governor, and a three-tier court system topped by the California Supreme Court. Layered on top of that framework, the state constitution reserves three tools directly to voters — the initiative, the referendum, and the recall — so Californians can make law and remove officials without going through the legislature at all. The current framework grew out of a major 1879 constitutional revision that replaced most of the state’s original 1849 document.1California Secretary of State. Constitutions
The Constitution That Sits Above Everything
The California Constitution is the state’s supreme legal authority. It creates each branch, sets out individual rights (some broader than federal protections), and reserves specific powers to voters. Under federalism, California keeps sovereignty over any subject the U.S. Constitution does not assign exclusively to the federal government. The document has been amended hundreds of times through both legislative action and voter-approved ballot measures, which is why it now ranks among the longest state constitutions in the country.
The Legislative Branch
Article IV vests the state’s lawmaking power in the California Legislature, made up of the State Assembly and the State Senate.2California Legislative Information. California Constitution Article IV – Legislative The Assembly has 80 members, each elected to a two-year term from a district of roughly 500,000 residents.3California State Assembly. Elected Officials The Senate has 40 members serving staggered four-year terms, so each senator represents close to one million people.4California State Senate. FAQs Proposition 28, passed in 2012, caps lifetime legislative service at 12 years for anyone first elected after the measure took effect, whether that time is spent in one chamber or split between the two.
Vote Thresholds for Passing Laws
A standard bill needs a simple majority in each house: 41 votes in the Assembly, 21 in the Senate.5California Energy Commission. Overview of Legislative Process Two categories require a two-thirds supermajority in each house instead: urgency statutes, which take effect immediately rather than on the following January 1,6Justia Law. California Constitution Article IV Section 8 and state tax increases, a restriction that dates to Proposition 13 in 1978. Bills that clear both chambers go to the Governor, who can sign, veto, or let the bill become law without a signature.
Vetoes and the Line-Item Reduction Power
A vetoed bill returns to its house of origin. The legislature can override, but only with a two-thirds vote of the full membership of each house, a threshold rarely met. On appropriations bills, the Governor also holds line-item authority: the power to reduce or eliminate specific spending items while signing the rest of the bill into law. Those individual reductions can be restored only through the same two-thirds override.7Justia Law. California Constitution Article IV Section 10
The Budget Deadline
The constitution requires the legislature to pass a budget bill by June 15 each year.8California Department of Finance. California’s Budget Process Since Proposition 25 passed in 2010, the budget itself clears on a simple majority, but any tax increase written into it still needs two-thirds support. Proposition 98, approved in 1988, sets a minimum annual funding guarantee for K–12 schools and community colleges based on a formula tied to state revenue and enrollment; suspending that guarantee for a single year also takes a two-thirds vote of each house.
The Executive Branch
California does not have a single chief executive who selects a cabinet. Voters independently elect eight statewide constitutional officers, each accountable directly to the public rather than to the Governor.9California Secretary of State. Constitutional Officers – California Roster All eight serve four-year terms with a two-term limit.10Justia Law. California Constitution Article V Section 2 The design fragments executive power on purpose, and officials from different offices sometimes pursue competing priorities.
The Eight Statewide Offices
The Governor holds the state’s supreme executive power, oversees state agencies, appoints judges, issues executive orders, and commands the California National Guard. The Lieutenant Governor presides over the Senate, casts tie-breaking votes, and becomes acting governor when the Governor leaves the state or a vacancy arises.11Lieutenant Governor of California. About the Office of Lt. Governor
The other six offices each run a distinct part of state operations:
- The Attorney General is the state’s chief law officer, heading the Department of Justice and representing California in legal proceedings.
- The Secretary of State runs elections, maintains official state records, and registers businesses.
- The Controller is the chief fiscal officer, auditing state spending and disbursing state funds.
- The Treasurer manages the state’s investments, cash flow, and bond sales.
- The Insurance Commissioner regulates California’s insurance market, investigates fraud, and enforces consumer protections for policyholders.12California Department of Insurance. About the Commissioner
- The Superintendent of Public Instruction leads the state’s public education system, and is the only statewide constitutional officer elected on a nonpartisan ballot.
California also elects four Board of Equalization members by district. The Board’s role narrowed after 2017 legislation shifted most of its tax-administration duties elsewhere; it now focuses mainly on property tax assessment standards and certain excise taxes.13California State Board of Equalization.

Agencies and the Rulemaking Check
The Governor appoints the heads of major state agencies, who together form the Governor’s cabinet.14Governor of California. Governor’s Cabinet These agencies do the day-to-day work of state government across areas like environmental protection, health and human services, natural resources, transportation, labor, and corrections. When an agency needs to write detailed rules to carry out a statute, it must go through a formal rulemaking process overseen by the Office of Administrative Law, which requires public notice, a comment period, and review before a regulation can take effect.15Office of Administrative Law. Rulemaking Process That process is what keeps unelected agencies from quietly issuing rules with the force of law.
The Judicial Branch
Article VI creates a three-tier court system: trial courts at the base, intermediate appellate courts in the middle, and the Supreme Court at the top.16California Legislative Information. California Constitution Article VI – Judicial How judges reach the bench differs at each level.
Superior Courts
California has 58 superior courts, one in every county. These are the trial courts where civil disputes, criminal cases, family law matters, and small claims all begin.17Judicial Branch of California. Superior Courts Superior court judges serve six-year terms and are elected on a nonpartisan, county-wide ballot. In practice, many first reach the bench through a gubernatorial appointment to fill a mid-term vacancy, then face voters at the next scheduled election.18Justia Law. California Constitution Article VI Section 16
Courts of Appeal
A party who believes the trial court made a legal error can appeal to one of California’s six appellate districts, organized by geography.19California Courts Newsroom. Courts of Appeal Appellate justices do not retry cases or hear new testimony. They review the trial record for legal error. Justices are appointed by the Governor and confirmed by the Commission on Judicial Appointments, made up of the Chief Justice, the Attorney General, and the senior presiding justice of the relevant district.20Judicial Branch of California. Commission on Judicial Appointments They then face retention elections, where voters decide yes or no on whether the justice should stay, and serve 12-year terms.21California Courts Newsroom.

The Supreme Court
The California Supreme Court has one Chief Justice and six Associate Justices, all appointed by the Governor and confirmed by the same commission that reviews appellate justices.22Supreme Court of California. Justices of the Court The court chooses most of its docket, taking up cases where the law is unsettled or where appellate districts have reached conflicting conclusions. One category is not discretionary: death penalty cases go directly from the trial court to the Supreme Court for automatic review.23California Courts Newsroom.

Direct Democracy: The Voters’ Own Powers
Article II reserves three tools to voters that bypass the legislature: the initiative, the referendum, and the recall.25California Legislative Information. California Constitution Article II
Initiatives
An initiative lets voters propose a new statute or a constitutional amendment and put it on the ballot. Qualifying a statute takes signatures from registered voters equal to 5 percent of the total votes cast for governor at the last gubernatorial election; a constitutional amendment takes 8 percent.26Justia Law. California Constitution Article II Section 8 Based on the 2022 gubernatorial election, that currently works out to 546,651 valid signatures for a statute and 874,641 for a constitutional amendment.27California Secretary of State. How to Qualify an Initiative Collecting that many valid signatures costs enough that most successful campaigns rely on professional signature-gathering firms.
Referendums
A referendum lets voters block a law the legislature has already passed. It takes signatures equal to 5 percent of the last gubernatorial vote, and proponents have only 90 days from the date the Governor signs the bill to gather them.28California Secretary of State. Referendum Once a petition qualifies, the law is suspended until voters decide its fate at the next statewide election. The tight 90-day window is why referendums qualify far less often than initiatives.
Recalls
The recall lets voters remove an elected official before the end of a term. For statewide officers like the Governor, proponents need signatures equal to 12 percent of the votes cast in the last election for that office, drawn from at least five counties. For state legislators, appellate justices, and superior court judges, the threshold rises to 20 percent. Proponents have 160 days to file the signed petitions with the Secretary of State.29Justia Law. California Constitution Article II Section 14 If enough valid signatures come in, a special recall election follows.
Local Government
California’s structure continues below the state level. The state has 58 counties that function largely as administrative arms of the state, delivering services like law enforcement, public health, property assessment, and elections. Of those, 43 are general law counties, meaning state statutes set their organizational structure, while 15 have adopted charters giving them more flexibility over their own governance. All counties are run by an elected five-member Board of Supervisors.
Cities operate with more independence than counties. A general law city follows the default rules set by the legislature; a charter city adopts its own foundational document (essentially a local constitution) with broader authority over municipal affairs like government structure, election procedures, and employee compensation. Roughly a quarter of California’s nearly 500 cities have charters, but because those tend to be larger cities, they hold well over half the state’s population. The distinction matters: when a charter city’s rules conflict with state law on a “municipal affair,” the charter generally controls.
