where does it say supreme court justices serve for life
Article Three of the United States Constitution The Constitution provides that judges "shall hold their Offices during good Behavior." The term "good behavior" is interpreted to mean that judges may serve for the remainder of their lives, although they may resign or retire voluntarily. A judge may also be removed by impeachment and conviction by congressional vote (hence the term good behavior); this has occurred fourteen times. Three other judges, Mark W. Delahay,[4] George W. English,[5] and Samuel B. Kent,[6] chose to resign rather than go through the impeachment process.
