Every ranking is computed transparently from the records, links to each judge, court, school, and appointing president it names, and shows its method. More unlock as the federal bench grows.
The Supreme Court confirmations that came closest to an even Senate split, ranked by the share of the recorded roll-call that voted to confirm rather than the raw margin, so a lopsided tally in a smaller historic Senate does not read as close. Voice votes with no recorded tally are excluded.
Currently serving Article III judges (active or on senior status: senior judges still hear cases), ranked by age. Ages are computed from birth year, so they are approximate to the year.
Currently serving Article III judges ranked by years since their first federal commission (active or on senior status: senior judges still hear cases).
Ranked by total Article III appointments on the complete federal record: the Supreme Court, the Courts of Appeals, the District Courts, and the specialized courts. Each president links to everyone they appointed.
