Supreme Court justices in the United States hold their offices during "good Behaviour," which effectively means they have life tenure. They serve until they die, resign, retire, or are impeached and removed from office. The only method to remove a justice from office is through impeachment by the House of Representatives and conviction by the Senate. This life tenure is intended to ensure judicial independence and protect justices from political pressures. There have been proposals for term limits, such as fixed 18-year terms, but currently, justices serve for life unless removed through impeachment.
