What are some unique aspects of California’s judicial branch?

The California judiciary is the largest judicial system in the United States surpassing the size of the entire federal judiciary. While it shares a three-tiered structure with most other states, it differs significantly in its selection of judges, size, and specific procedural rules.

Scale

California features the largest state court network in the nation, with some individual appellate districts representing populations larger than entire states, with over 1,800 judicial officers and 18,000 employees.

Tiers

Like most states and the federal courts, California uses a three-level system:

• Supreme Court: Composed of one Chief Justice and six associate justices (7 total). which matches the most common number across U.S. states (state high courts range from 5 to 9 justices). Roughly 20 states elect their high court justices directly, while the remaining states (including California) use an appointive or commission-based system.

• Courts of Appeal: Divided into 6 geographic districts with over 100 appellate judges.

• Superior Courts: 58 trial courts—one for each California county (unlike states that group trial courts into multi-county judicial districts).

How Judges Are Selected and Retained

Appellate Justices (Supreme Court & Courts of Appeal): Appointed by the Governor, reviewed and confirmed by the Commission on Judicial Appointments, and then must face periodic retention elections every 12 years (where voters vote “yes” or “no” to keep them on the bench). Four states grant lifetime appointments.

Trial Judges (Superior Courts): Officially chosen via nonpartisan elections by local voters, though the Governor has the power to appoint judges to fill mid-term vacancies (who then eventually run in an election).

While many states use merit selection, partisan elections, or lifetime and lengthy mandatory retirement ages, California’s blend of gubernatorial appointment with long 12-year retention cycles for appellate benches and direct county elections for trial courts is distinct.

Governance and Administration

California utilizes a powerful, centralized Judicial Council (chaired by the Chief Justice) that sets statewide rules, policy, and budget management for all local courts, providing more top-down administrative coordination than found in many decentralized state systems.

California utilizes a dedicated Commission on Judicial Performance to investigate complaints of ethical misconduct or disability by judges, a model distinct from states that rely solely on legislative impeachment or state supreme court self-policing.
