Cal. Elec. Code § 9083
If the ballot contains a question as to the confirmation of a justice of the Supreme Court or a court of appeal, the Secretary of State shall include in the state voter information guide a written explanation of the electoral procedure for justices of the Supreme Court and the courts of appeal. The explanation shall state the following:
"Under the California Constitution, justices of the Supreme Court and the courts of appeal are subject to confirmation by the voters. The public votes "yes" or "no" on whether to retain each justice.
"These judicial offices are nonpartisan.
"Before a person can become an appellate justice, the Governor must submit the candidate's name to the Judicial Nominees Evaluation Commission, which is comprised of public members and lawyers. The commission conducts a thorough review of the candidate's background and qualifications, with community input, and then forwards its evaluation of the candidate to the Governor.
"The Governor then reviews the commission's evaluation and officially nominates the candidate, whose qualifications are subject to public comment before examination and review by the Commission on Judicial Appointments. That commission consists of the Chief Justice of California, the Attorney General of California, and a senior Presiding Justice of the Courts of Appeal. The Commission on Judicial Appointments must then confirm or reject the nomination. Only if confirmed does the nominee become a justice.
"Following confirmation, the justice is sworn into office and is subject to voter approval at the next gubernatorial election, and thereafter at the conclusion of each term. The term prescribed by the California Constitution for justices of the Supreme Court and courts of appeal is 12 years. Justices are confirmed by the Commission on Judicial Appointments only until the next gubernatorial election, at which time they run for retention of the remainder of the term, if any, of their predecessor, which will be either four or eight years."
