How to interpret this record

Jose S. Castillo: Associate Justice, California Court of Appeal, Fourth Appellate District, Division One (San Diego)

A court, a judgeship and a judge are related but distinct records. Judicial research starts with the court’s jurisdiction and the type of appointment or election involved.

Identify the court first

Federal and state courts are different systems, and trial and appellate courts have different roles. A biography should be read with the court, position and service dates it actually describes. A court directory can establish membership of a body without establishing that every member is appearing on the current ballot.

Understand the judicial ballot

A judicial ballot question may ask voters to retain or elect a named judge, depending on the jurisdiction and proceeding. In a yes-or-no question, begin with the exact official wording and the published effect of each choice. Do not assume the page describes a head-to-head race, a partisan primary or a choice that applies statewide unless the source says so.
