There should be term limits for Supreme Court justices because life tenure, as it works today, produces 30-year careers, random vacancies that turn every confirmation into political warfare, and a Court whose composition can lag a generation behind the country it governs. The most prominent proposal, 18-year staggered terms, would give every president exactly two appointments and replace actuarial luck with a predictable cycle. Roughly two-thirds of Americans already support some version of the idea, with majorities in both parties.
Justices Now Serve Far Longer Than the Framers Expected
Article III says federal judges hold their offices “during good Behaviour,”1Cornell Law School. U.S. Constitution Annotated Article 3 Section 1 Good Behavior Clause Overview which in practice has meant life tenure removable only by impeachment. That design was built for an era with much shorter lifespans. For most of the period since the Civil War, the median justice served about 15 years. Justices who left the Court since 1970 have averaged roughly 25 years. Justice Clarence Thomas, appointed in 1991, has now served more than 34 years.2Supreme Court of the United States. Current Members
A single appointment now shapes American law across five or six presidential administrations. No other decision a president makes carries that kind of durable weight, and nothing in the original constitutional bargain anticipated it.
Vacancies Arrive at Random, and That Distorts Democracy
Seats open only when a justice dies, retires, or resigns. Some presidents get to fill three or four; others get none. The resulting unpredictability has made each confirmation a bare-knuckle fight, because both parties understand that the outcome can lock in a direction for the law long after any given election is forgotten.
Justices themselves participate in the gaming, timing retirements to hand their seat to a politically sympathetic president. The direction of the Court ends up depending less on who wins elections than on who happens to be in the White House when a justice’s health fails or their patience runs out. Term limits replace that lottery with a schedule. Under the leading proposal, a vacancy would occur every two years, in the first and third years of each presidential term, so every president appoints two justices and no more.3Senate. Whitehouse, Booker, Blumenthal, Padilla Introduce New Supreme Court Term Limits Bill That alone would end strategic retirements and the recurring crisis of the surprise vacancy.
Public Trust Is Falling and the Accountability Gap Is Widening
A July 2025 Gallup poll put Supreme Court approval at 39 percent, with a 64-point partisan gap: 75 percent of Republicans approve, 11 percent of Democrats. A separate poll found 67 percent of Americans support replacing life tenure with a fixed number of years, including 82 percent of Democrats and 57 percent of Republicans. Numbers like those suggest the public has stopped seeing the Court as a neutral arbiter.
The ethics picture compounds the problem. The Supreme Court is the only level of the federal judiciary, and the only court system in the country when state courts are included, that lacks a binding, enforceable code of conduct.4Congressman Hank Johnson. Congressman Johnson Leads Letter Urging Justices To Adopt Binding Code of Conduct The American Bar Association has said the Court’s self-adopted code meets neither the standards applied to other federal judges nor the basic requirement of an enforcement mechanism. Term limits do not fix ethics problems directly. They do shorten the window in which any single justice operates without meaningful accountability, and they give the appointment process a regular opportunity to apply evolving conduct expectations.
Every Other Established Democracy Has Already Done This
The United States is alone among established constitutional democracies in granting its highest-court justices unlimited tenure. Since 1993, U.S. justices have averaged 28.2 years of service, more than double the average in peer nations. Germany caps constitutional court terms at 12 years with no reappointment. France and Italy use nine-year limits. Canada and Australia rely on mandatory retirement ages that produce average tenures around 12 and 13 years. The United Kingdom’s Supreme Court justices average about seven and a half years under a retirement age of 75. Japan’s average under six.
None of these judiciaries is noticeably less independent for the arrangement. Germany’s Federal Constitutional Court, operating under a hard 12-year limit, is one of the most respected courts in the world. The lesson is that judicial independence comes from institutional design, not from indefinite tenure.
What 18-Year Staggered Terms Would Actually Do
Under the leading proposal, each new justice would serve 18 years of active service. After that, the justice would shift to senior status, continuing to hold the Article III office and hearing a limited caseload rather than leaving the judiciary.5Office of the Law Revision Counsel. 28 U.S. Code 371 – Retirement on Salary; Retirement in Senior Status A successor fills the active seat. One appointment every two years, two per presidential term, nine active justices at any moment.
Most proposals apply only to future appointees. The Judicial Term Limits Amendment introduced in the House in early 2026 explicitly grandfathers in sitting justices, phasing the system in gradually as current members leave the bench.6Representative Tom Barrett. Barrett Introduces Constitutional Amendment to Establish Term Limits for Federal Judges That design avoids any appearance of targeting an individual justice, at the cost of a slow transition.
Whether this can be done by statute or requires a constitutional amendment is contested, and it matters: a statute would almost certainly be challenged, and that challenge would land before the justices whose tenure was at stake.7Legal Information Institute. Good Behavior Clause Doctrine and Practice An amendment is immune to that problem but requires two-thirds of Congress and three-fourths of state legislatures. Neither route has reached a floor vote.
The Case Against Term Limits
The argument for life tenure is not just tradition. Alexander Hamilton’s concern in Federalist No. 78 was that judges with limited terms would feel political pressure, not that they would be free of it.8Legal Information Institute. Good Behavior Clause Historical Background A justice looking at the end of an 18-year term might also be looking at a future job in academia, private practice, or politics, and that calculation could shape rulings in ways life tenure was built to prevent.
Critics also warn about escalation. If one Congress restructures the Court through term limits, the next might expand seats, shrink them, or shorten terms further. Court-packing proposals have already entered mainstream debate, and opponents argue that any structural change invites more aggressive ones.
There is also the loss of institutional knowledge. Constitutional cases are hard, and experienced justices bring something newer ones cannot. A hard 18-year ceiling means the Court would never again have a justice with more than 18 years on the bench.
What Term Limits Would and Would Not Fix
Academic simulations using presidential election and justice lifespan data from 1937 to 2010 found that under 18-year staggered terms the Court’s ideological majority would have flipped about 1.3 times every 20 years. Specific legislative versions produced between 0.6 and 0.8 flips per 20 years. More predictable than the current system, but not neutral.
The same simulations found that even with 18-year terms, one party would still hold seven or more of nine seats about 22 percent of the time under the most favorable scenarios, and up to 42 percent under some proposals. Term limits remove the randomness that currently lets a single party dominate the Court for decades at a stretch. They do not guarantee an ideologically balanced bench, and no honest version of the reform promises that. What they do is tie the Court’s composition to recent elections on a predictable cycle, instead of to who happened to be president when a justice’s heart gave out.
