The Federal and California Court Systems

Article III of the U.S. Constitution establishes the Supreme Court, which consists of one chief justice and eight associate justices. Federal justices are nominated by the president and confirmed by the Senate, serving life tenure with protected salaries. The judiciary is historically viewed as the least dangerous branch, yet it holds significant authority through appellate jurisdiction, allowing it to review decisions from lower federal and state courts.

The federal court system originated with the Judiciary Act of 1789, which established circuit and district courts. The legal system is divided into trial courts, which hear cases initially, and appellate courts. California's state system is similarly structured, featuring superior court divisions organized into six appellate districts and a California Supreme Court currently led by Chief Justice Patricia Guerrero.

Cases reach the U.S. Supreme Court primarily through a writ of certiorari, where the Court selects important cases to review. Parties may also submit amicus curiae briefs. In the California Supreme Court, four justices must agree for a party to prevail. Judicial decision-making is fundamentally shaped by the power of judicial review, established by Marbury v. Madison (1803), which grants the Court the authority to determine the constitutionality of state and congressional laws.
