The smallest federal appellate court in America holds a unique, rotating leadership structure.

In short: Spanning New England and Puerto Rico, the First Circuit is the most compact of the thirteen federal appellate courts. Despite its modest size, it wields significant power, recently becoming a focal point for national debates on immigration policy and the legal standards governing the deportation of migrants to third countries.

Headquartered at the John Joseph Moakley Federal Courthouse in Boston, the First Circuit maintains a distinct geographic footprint. While it primarily operates in Massachusetts, the court periodically convenes in Old San Juan, Puerto Rico, for one week each March and November. This jurisdiction covers Maine, New Hampshire, Rhode Island, Massachusetts, and Puerto Rico, making it the smallest of the thirteen federal appellate courts by judge count, currently operating with six active judges and five senior judges.

The court's leadership model is notably distinct from the Supreme Court. Rather than a permanent appointment, the role of chief judge shifts among the circuit's members. To qualify for this administrative position, a judge must be under 65, have served on the court for at least one year, and never have held the title previously. The position is filled by the most senior eligible judge, who serves a seven-year term or until they reach age 70. These rules, which have been in effect since October 1, 1982, ensure a revolving door of leadership.

The court’s influence on American life is substantial, often setting precedents that ripple outward. For instance, the 1820 case West v. Randall helped establish the foundation for modern class action litigation. More recently, in September 2026, the court addressed the Department of Homeland Security's third-country removal policy. Circuit Judge Seth R. Aframe ruled that migrants must be informed of their destination and granted a meaningful chance to contest removals based on fears of torture or persecution. While the Supreme Court later paused this ruling to consider the merits, the case highlights the First Circuit's role as a critical arbiter of federal law.
