Article III establishes judicial independence through two mechanisms: lifetime tenure and salary protection. Federal judges hold office "during good Behaviour," which courts interpret as lifetime tenure barring impeachment and conviction. Their compensation cannot be "diminished during their Continuance in Office," preventing Congress from cutting judges' pay to punish unpopular rulings.
The Framers believed judges needed insulation from political pressure to rule according to law rather than popular opinion or executive pressure. Alexander Hamilton argued in the Federalist Papers that judges, lacking control over military force or the purse, required lifetime tenure to resist coercion. These protections allow judges to issue decisions that anger the president, disappoint Congress, or frustrate the public without fear of losing their jobs or income. Only eight federal judges have ever been impeached, and none convicted in over two centuries—the standard "for cause" (impeachment) is extraordinarily high.
Contemporary debate centers on whether lifetime tenure has had unintended consequences. Justices now serve 25-30 years; recent Supreme Court vacancies have become major political events with confirmation battles dominating the news cycle. Term limits proposals recur: critics argue rotational terms would reduce politicization of vacant seats, while defenders maintain any change would weaken judicial independence by making judges sensitive to their post-judicial careers.
Judicial independence ensures judges can interpret law impartially. Without it, politicians could threaten judges' jobs to force favorable rulings, destroying rule of law. But longevity also shapes whose constitutional values dominate for decades.
Some think judicial independence means judges are immune from all removal. It doesn't—impeachment and conviction remain possible, though rare. Also, lifetime tenure doesn't prevent judges from retiring.
