Federal vs state judges: how they are chosen
By JudgeFinder Editors · Published · 4 min read
Federal judges are nominated by the President, confirmed by the Senate and hold office during good behavior, which typically means for life. State judges reach the bench in many ways, including election, appointment for a set number of years, appointment for life, and combinations of these. Your case lands in one system or the other depending on the kind of dispute, and the judge's background and accountability differ with it.
How federal judges are chosen
The Constitution says federal judges are nominated by the President and confirmed by the Senate. Judges of the Supreme Court, the 13 courts of appeals and the 94 district courts hold office during good behavior. Congress can remove a judge for misbehavior through impeachment. These judges do not stand for election or reappointment.
Other federal judicial officers serve under different rules:
- Bankruptcy judges are appointed by the court of appeals for their circuit for a term of fourteen years. There are 90 bankruptcy courts.
- Magistrate judges are appointed by the district court's judges. A full-time magistrate judge serves an eight-year term, and a part-time one serves four years.
When a federal profile says "judge," check which kind. A magistrate judge may decide discovery disputes and manage the case before a district judge takes over for trial, and the terms of service are not the same.
How state judges are chosen
Each state writes its own rules. The U.S. Courts summary lists the range: election, appointment for a given number of years, appointment for life, and combinations such as appointment followed by election. Terms, qualifications and the way a judge is retained or removed vary by state, sometimes by court within a state.
California shows how mixed a single state can be. The state's courts office describes it this way:
- Superior court judges, in each of the 58 counties, serve six-year terms and are elected by county voters on a nonpartisan ballot. When a seat opens during a term, the Governor appoints a replacement, and the California courts office says most superior court judges first reach the bench by appointment. An unopposed incumbent does not appear on the ballot.
- Court of Appeal and Supreme Court justices are appointed by the Governor and confirmed by the Commission on Judicial Appointments. They serve 12-year terms and face voters in retention elections, where the question is whether the justice should stay.
Side by side, a federal district judge and a California superior court judge look like this:
| Federal district judge | California superior court judge | |
|---|---|---|
| How selected | Nominated by the President, confirmed by the Senate | Elected by county voters, with vacancies filled by the Governor |
| Length of service | During good behavior, typically for life | Six-year terms |
| Removal or discipline | Impeachment by Congress for misbehavior | Discipline, including removal, through the Commission on Judicial Performance, and the voters at each election |
Another state may elect appellate judges in contested races, or appoint trial judges for life. Do not assume California's mix applies elsewhere. Our California county courts guide covers how its trial courts work in practice.
Who hears which cases
The U.S. Courts comparison draws the line this way. Federal courts hear cases about the constitutionality of a law, cases involving federal laws and treaties, cases involving ambassadors and public ministers, disputes between states, admiralty, bankruptcy and habeas corpus. State courts hear most criminal cases, probate, most contract cases, tort cases such as personal injury, and family law such as divorce and adoption.
There is one more common route into federal court. Under 28 U.S.C. section 1332, a federal district court can hear a civil case between citizens of different states when the amount in controversy exceeds $75,000, exclusive of interest and costs. That is called diversity jurisdiction, and it is a narrow rule with its own exceptions.
State courts are the final authority on state law and state constitutions. A state court's reading of federal law or the U.S. Constitution can be appealed to the U.S. Supreme Court, which chooses whether to take the case.
What the difference means for research
The research path changes with the system.
- Federal judges. The Federal Judicial Center's biographical directory covers appointment, education and prior career. Financial disclosure reports and docket history are public. See how to research a federal judge.
- Elected state judges. Expect campaign materials, voter guides and, in some states, official evaluation results published before retention elections. What judicial ratings mean explains how to read them.
- Appointed state judges. Look for the commission or governor's announcement that documents the appointment and the judge's earlier career.
In every system, the most useful documents are the judge's own rules and orders for your type of case.
What JudgeFinder covers
JudgeFinder's judge profiles cover federal judges, built from CourtListener docket metadata. The index also lists some California state courts, but no state court has linked judges yet, so there is no state judge profile to find. If you need a state judge, start with the state's judicial branch website or the county court's own judge directory. The data sources page states the current coverage and its date.
