How long a judge can serve depends entirely on which court they sit on. Federal judges appointed under Article III of the Constitution — Supreme Court justices, appeals court judges, and district court judges — serve for life, with no term limit and no mandatory retirement age. Other federal judges serve fixed terms set by statute, ranging from eight to fifteen years. State judges almost always serve fixed, renewable terms between six and fourteen years, and roughly two-thirds of states force them off the bench at a set age.
Article III Federal Judges Serve for Life
The Constitution grants Supreme Court justices, U.S. Court of Appeals judges, and U.S. District Court judges their positions “during good Behaviour,” which has always been read to mean for life.1Cornell Law School / Legal Information Institute (LII). U.S. Constitution Article III There is no term limit. No mandatory retirement age. No reconfirmation. A sitting Article III judge leaves the bench only voluntarily or through impeachment and conviction by Congress.
That second route is rare. In the entire history of the federal judiciary, only fifteen judges have been impeached by the House of Representatives, and just eight of those were convicted and removed by the Senate. A 95-year-old Supreme Court justice has exactly the same legal right to remain seated as a 50-year-old district judge.
Federal Judges Who Serve Fixed Terms
Several categories of federal judges work in courts Congress created under its legislative authority rather than under Article III. They serve renewable terms:
- Magistrate judges serve eight-year terms if full-time and four-year terms if part-time. They handle pretrial matters, misdemeanor cases, and other work delegated by district judges. They face a mandatory retirement age of 70, though the appointing court can vote to let them continue year by year past that point.2Office of the Law Revision Counsel. 28 USC 631 – Appointment and Tenure
- Bankruptcy judges serve fourteen-year terms. The court of appeals for the circuit appoints them and may reappoint the incumbent when a term expires.3Office of the Law Revision Counsel. 28 USC 152 – Appointment of Bankruptcy Judges
- U.S. Court of Federal Claims judges serve fifteen-year terms.4Office of the Law Revision Counsel. 28 USC 172 – Tenure and Salaries of Judges
- U.S. Tax Court judges serve fifteen-year terms after presidential appointment and Senate confirmation.5Office of the Law Revision Counsel. 26 USC 7443 – Membership
- Territorial court judges in the U.S. Virgin Islands, Guam, and the Northern Mariana Islands serve renewable ten-year terms after presidential appointment and Senate confirmation.6U.S. Courts. Types of Federal Judges
These judges can also be removed mid-term through statutory procedures rather than impeachment. Court of Federal Claims judges, for instance, can be removed by a majority vote of the U.S. Court of Appeals for the Federal Circuit for incompetency, misconduct, neglect of duty, or physical or mental disability, after being given a full specification of the charges and an opportunity to respond.7Office of the Law Revision Counsel. 28 USC 176 – Removal From Office
State Court Judges Serve Fixed, Renewable Terms
The vast majority of states use fixed, renewable terms rather than lifetime appointments. Forty-seven states set specific terms for their supreme court justices, with those terms ranging from 6 to 14 years and averaging about 8 years. Trial court judges often serve shorter terms than appellate justices within the same state. Only three states allow supreme court justices to serve indefinitely after their initial appointment, and even those three impose a mandatory retirement age.
Most states do not cap the number of terms a judge can serve. A judge who keeps winning elections or retention votes can remain on the bench for decades. The practical limit is politics or age, not a statutory ceiling.
When a state judge leaves before the term expires, the governor typically appoints a replacement, often with input from a judicial nominating commission. The appointed judge then serves until the next scheduled election or for the remainder of the original term, depending on state rules.
Mandatory Retirement Ages by State
Roughly two-thirds of states impose a mandatory retirement age for their judges, with cutoffs ranging from 70 to 90. Once a judge hits that age, they must step down regardless of how much time remains on their term. Some states set the cutoff at 70; others stretch it to 75 or beyond.
Senior Status: How Life Tenure Actually Ends
Most Article III judges don’t stay in the top job until they die. They take “senior status,” a kind of semi-retirement where they keep their title and salary but carry a reduced caseload, and their old seat opens up for a new appointment.
To qualify, a judge must satisfy the Rule of 80: age plus years of federal judicial service must total at least 80, with a minimum age of 65 and a minimum of 10 years on the bench.8Federal Judicial Center. The Evolution of Judicial Retirement The specific combinations run from age 65 with 15 years of service to age 70 with 10 years of service.9Office of the Law Revision Counsel. 28 USC 371 – Retirement on Salary; Retirement in Senior Status
Senior status is not a vacation. To keep drawing a full salary, a senior judge must be certified each year as having performed the equivalent of at least three months of the work an active judge would handle — courtroom participation, writing opinions, resolving motions, or substantial administrative duties for the courts.9Office of the Law Revision Counsel. 28 USC 371 – Retirement on Salary; Retirement in Senior Status A judge with a permanent disability is exempt from the certification requirement.
A judge who instead retires outright after meeting the Rule of 80 receives an annuity equal to the salary of the office at the time of retirement, payable for life.9Office of the Law Revision Counsel. 28 USC 371 – Retirement on Salary; Retirement in Senior Status
Removing a Judge Before Their Time Is Up
For an Article III federal judge, impeachment is the only path to involuntary removal. The House of Representatives votes on articles of impeachment by simple majority. If that passes, the Senate holds a trial and must vote to convict by a two-thirds majority. The process is deliberately hard, which is why it has been used so rarely.
State systems offer more options. Some states use an impeachment process similar to the federal model, but every state maintains a judicial conduct commission that investigates complaints against sitting judges. These commissions look into allegations of ethical misconduct, bias, conflicts of interest, and inability to perform duties. If a commission finds serious problems, it recommends action to the state supreme court, which can impose sanctions from a private reprimand up to suspension or removal. This route is far more common than impeachment and handles everything from minor ethical lapses to serious corruption. A judge under investigation typically receives formal notice of the charges and a chance to respond before any public action.
